Picture of Repair a Broken Ethernet Plug
IMG_4386.JPG
The locking tab of RJ45 plugs breaks very easily. Replace it by two nylon cable ties (aka zip ties), in minutes.

IMPORTANT NOTES:
- This must be regarded as a temporary "Mac Gyver" solution, for home usage.
- Definitely not for IT staff! (no crimper? asking for one in the budget won't get you fired!)
- Before the tab breaks, consider protecting the plug.

Step 1: On Broken RJ45 Locking Tabs...

There are always some Ethernet cables around with a broken tab. Did you remember to exchange the cable?

Now the RJ45 plug no longer locks properly, making the connection unreliable. You firmly push the plug into the socket, hurray you're connected again! so you forget about the plug until the next lost connection some weeks later, wasting a long time to figure out that it's this damn broken plug again. And so on.

Now it's time to act and grab your RJ45 crimp tool. Oh, you don't have one? Or you're reluctant to use it? so read on...

Step 5: Make its Head Thin

With the sharp knife, and preferably on a piece of scrap material, cut the head of the cable tie, to make it flat.

Problem solved! We are not big fans of wireless networking. A broken plug is a big inconvenience. Fixing it saved us alot of money and frustriation. Great photos. Thank you very much.

I don't know what everyone is going on about, this took me 20 minutes max and it works perfectly. :)

I couldn't cut the head bit, as it is tough as nails. I tried with pair of sheers but it only made it uneven. So I took on another tip, tape the sides of the plug and it should make it snug. Works just fine.

Ah!!!!!!!!!! What a waste of time and disappointment. I wish I could be as positive as the others, but sorry, that's just not the case. I tried this, which took probably at least an hour with the cutting the head of the tie being the longest. It cracked to the top, but I managed to change the direction of the cut to get it even and finish the job. I also super-glued it and wiped off any excess. It eventually cracked again though.

Once I finally reached the last step, I am able to put it into my Ethernet port, but sometimes must fidget with it to get it pushed in all the way so that when I tug on it I can feel resistance. The second thing that bothered me the most is that it's too difficult to get out and I usually have to pull out my Ethernet cord as I have a non wireless printer that's not in my room and this would frustrate me every time I have to take the cord out.

I guess the easiest and fastest solution, would be to buy a coupler as someone else suggested and a one foot cord and tape the damaged end of the cord into the coupler.
glenneroo roseuz7 months ago

Absolutely agree! The idea is good, but I just spent an hour trying this with various cable-ties and I have to say, the cable is better off without this "fix". I just bought a RJ45 coupler and added another cable.

Sorry for the waste of time... but you have been warned by the important note in the intro. You shall consider this fix as a curiosity.

I've found super gluing a $3 inline coupler to be easier and more flexible.

dude you totally rock! :v
Thank you thank you and thank you so much. Almost every plug I have is broken and I was about to go buy new ends and recrimp them. Now I don't have to.
Love this. This seems like you would want this at the dedicated end,
correct ? Or is this a remedy that works for repeated plug in and unplug uses?

This might be fine s a temporary fix. But seriously, just crimp on a new end. They're as cheap as cheap as pull-ties, and you won't have to fiddle with getting the cuts just right. Any home improvement store carries the crimper and ends.

An excellent fix for an all too common problem. Saved me hours of laying new cables or renewing connectors. A simple and annoyingly obvious fix once you have seen it done once.

thanks mate for showing this. i applied to to my own cat-5 cable and also used the same application modified for my old telephone wire cable.

I can't cut the friggin nylon tie with an extremely sharp razor. Now what, sand it flat?
laxap (author)  prodo1233 years ago
Because the nylon is quite hard, a sharp and sturdy blade+handle is necessary. Use a utility knife (stanley, or snap-off).

Side cutting pliers may also be used.
prodo123 laxap3 years ago
I used a Stanley utility knife and it still won't cut...
Then I used wire cutters and it completely deformed the end
Then I used needle nose pliers and it did the same thing
Sorry but you made me laugh. Have you got a sharp blade installed in the knife? If you use a little backwards and forwards motion and gently push you will make it through the plastic clip. You could use some mineral oil to help with the friction. You have to have some patients, they are tough little pesky things.

If you have a little modelers drill you could use a small sander tip but that would defeat the whole point of this genius repair. Which can be done with little to no tools, I have managed to do this with a set of True Utility Nail Clippers. So keep going and you will succeed.

Good luck.
I got a new Ethernet cable, problem solved.
And yes, it was sharpened at that time. In fact, laying my finger over it got me a small cut. So it looks like there's something wrong with my cable ties. Or maybe it's some industrial-grade cable tie? I don't know.
Oh well . . . got here too late to tell you to try a finger nail clipper. The big ones with a wide flat Jaw for toe nails. This is what I plan to use instead.
This rocks more than a very rocky thing! Thank you!

I have a cable where the tab broke off from being plugged/unplugged every day, so this will be much better than the original tab because it's almost unbreakable!

Rybka30 lmlei3 years ago
I used it for few months... and then PC engineer said me it can break ethernet card in computer... i dunno how, but he said it can... :/
mmykle Rybka303 years ago
It can only break the port if you misjudge the how small to cut the ziptie. If it is too big the cable will get stuck in the port. However in most cases you should be able to get it out by sliding a knife in between the ziptie and the ethernet port.
Finally gave this a try on my cable that keeps coming loose. For a moment I thought it hadn't worked but then I nudged the ties forward a bit and it clicked and locked. Excellent job on this!

Great idea. If I didn't work in network repair and have a pile of connectors sitting around, I'd use it.

FYI if you have a plug you really need to be stable and not break, check out Panduit's RJ45 connectors, the tabs are built a little bit differently so they don't break as fast.

I always believed that cable ties could fix anything :)

There needs to be a GREAT SHOOT-OUT between Cable-Ties VS DUCT TAPE There should be at least 2 classes in this shoot out; one WITH a DREMAL Tool ALLOWED and the other class WITHOUT a DREMAL Tool ALLOWED :-) :-)

or

We need a similar slogan for the NEW SCHOOL 'bailing wire' guys who use high tech 'Zip-Ties' and 'Tie-Wraps'.
 Also I would like to include the 'VELCRO' guys too.

Blackwo WPee5 years ago
 haha I like it! :D I have to admit I use Duct tape to fix like EVERYTHING. hardly use cable ties...
Supplies needed. 1.Super glue (5g tube or whatever!) 2 Rubber band (About the same width as the plastic TAB LEVER CLIP THING!) Gather the snapped off lever tab (assuming you have it?) and the rubber band. Cut band to roughly same length as tab then apply super glue to the plastic tab but before glueing to the terminal plug put the rubber band beneath the tab & wedge it under the so it fits snugly under the part that's still attached to the plug so when re-joining the broken tab and letting the adhesive take hold leave for a while 'till the certainty that it won't just snap again (don't be inpatient! ) & when using it the plug now has the reassurance of the rubber band to stop it from breaking again.

Well mines been great for quite a good while now!
snapshot71.jpeg
laxap (author)  Cap_n_Scarlet4 years ago
Great hack too (provided you still have the broken tab)!
The rubber band would solve the breakage if placed there in the first place.
Mine break because of constant removal so the rubber cushions the stress.
I see the sugru stuff protect the tab in the other inscrutable but that's not cheap and looks crap IMO , but whatever rocks your boat. It's given me an idea to look for something to act as a boot so off I goes.
Thanks for the inspiration!

rocketguy5 years ago
Nice Hack! This is a great improvised solution, for where that's appropriate.

Furthermore, I'd like to see a tab design that is more like this than the current style, as I've only seen one that doesn't suck, and it's pretty much the same idea but attached at both ends, sorta like a leaf spring.

Two bits of advice though: as others have noted, crushing the cable is both easy to do and a bad thing. I was thinking 5min epoxy on the jack head, but that would be harder to do right. Just be careful I guess.

Secondly, the days of building your own cables is really past, *don't* do it! As much as I love DIY, hand crimping doesn't hold a candle to the $20K machine that does factory made cables, crimp depth and so forth are regulated at the factory, not at the hand crimper. They're generally cheaper store bought than the time you'd spend messing around with it, and goal #1 is reliability.

A bad hand crimp (and they're virtually impossible to do well) can really take a long time to figure out while troubleshooting. The fault can be both intermittent and not bidirectionally broken. The worst part is that it's never clear if it's been done right, even if you have the right heads/cable type. I speak from vast networking experience, 60K+ node network and 16 years on the job. Just not worth it, resist the urge!
Have to disagree, as an IT Technician who installs cat5e cable professionally (for only 2 years, but I've done plenty of retail network installs/moves/remodels, 1000's of terminations, etc), crimping modplugs (rj45s, aka icecubes) is not brain surgery. If you know the basics, a $10 crimper will last you 2 years. The only 3 things you need: Crimper with adjustable stripper, Bag of icecubes, RJ45 4pair Continuity tester. $18.95 on ebay from hongkong, these packages last quite awhile if you take care of them. After you crimp your 2 ends, run the continuity tester while moving around the cable near the modplug. If you get a short(s), cut and reterminate that end. I sell custom length patch cables all the time too and have never had a complaint or return. Do not be afraid to DIY regardless of what people within the industry say!!!
Glad you've had success with it, but on a broader scale and long term, I've seen problems. You can have success with it, but the issue I have is reliability, and in my experience it's something that folks are "getting away with". Sure it will work, even most of the time, but not as well as a precision made cable. This is probably more of an issue for me running a larger enterprise than most businesses. Your odds of having a bad cable in a smaller install is of course less, and if you're doing it all day you're probably better than the occasional use guy. Also you've got a tester, so you've got a fighting chance there. With stranded core and the right type of ends to match, you'll probably do fairly well. I used to do cable installs, much like yourself, and also worked for companies that had their own cable fab plants (where I encountered the aforementioned expensive auto-uber-crimpers), now I'm responsible for a huge and very diverse network. I see everything possible, and a few things that really shouldn't be. (Flat Satin on RJ-45's -CAT-Zero! what moron put this in!?!). In any case, the time spent on custom cables is really only justified cost/benefit wise if there's some specific real need other than "didn't have that length". I'm a huge DIY guy, but I know how to pick my battles. I don't build my own refinery for car oil either. My bar for reliability is very high because I don't have time to fix things at this scale. We run a 60,000+ node network with about 10 guys, so it's gotta be solid. My trouble duty rotations have put me in a position to see what technologies work, and which don't with a large statistical base. But hey, y'all are adults and make up your own minds. I use the best car oil I can find, as the extra $40 saves me $1000's down the road, and I use good network gear as downtime is more expensive in the long run than any equipment cost that's reasonably possible. Last thing, You're just as much "in the industry" as I am. Not like I sell the damn things, I just have to fix it when it's broke.
You have a great point, I can see why you wouldn't want to make every single patch cable within a 60k+ node environment, and for someone responsible for reliability of networks that large, you really wouldn't want to dabble around with crimping/testing patchcables all day. That's agreed. And TBH, I would never mess around with making short patch cables unless I need one in a pinch. With so many people moving to wireless routers, you can pick them up pretty cheap now. Mostly I get calls for 75-100' cables, where people are saving a substantial amount of money buying it from the guy with the bulk cat5e cable boxes for $10 instead of paying $25+ for one (about the cost of 500') instead. I don't mind helping people out locally, selling my leftover patch cables for cheap that I collect from jobs, etc. I only make $2-10 per cable but it costs me nothing to offer them on craigsli st. It's just the DIY mentality I'm trying to promote with that reply. When you have a small network of 2-3 computers, its much more cost efficient to find someone to make you cables and plug them in yourself than to hire a network professional to do the work for you. Your company probably saves a lot of money by buying their patch cables in bulk, but consumers end up paying a lot more in a retail store for something that works no better or worse than one that I make in 2.7 minutes. You are correct and logical in every point you make, we just come from opposite ends of the spectrum. I'm from the school of: stay 2-3 generations behind the 'newest thing' for reliability, cost, and knowledge pertaining to the technology. If something breaks, it costs me much less to replace. New technology only lasts so long anyway. All consumer electronics are engineered to break these days anyway.. I digress =]
amplex amplex5 years ago
On another note: you can buy 100' patch cables for $5 off ebay if you don't mind waiting a few days for them to be shipped =] Pretty cheap compared to say radioshack which wants something like $30-60 for a 100'er. Retail stores sometimes have 100x markup on items like this, which is where they make all their money (used to work @ CompUSA 10 yrs ago, where these items were the only thing that they made money on in the whole store, besides service plans). Premade cables should be very cheap, don't be fooled. And machine crimped/multiple LAN tested cables are way more reliable in general than some random persons custom crimped cable. But the ease/power of being able to make/test them yourself is what I was shooting for in my reply, more in the spirit of this site.
Your ready-made cable is fine, if all you're going to do is run it across the floor.  Mine all go under the house.  I'd have had to drill a 5/16" or larger hole in the floor  instead of the 1/4" or smaller hole to pull a bare cable.  Even the hooded connectors get snagged when you're doing jobs like that.

Bare cable/hand-crimped connectors is the only way to go in these situations.

(Tip: always drill the hole between the baseboard and quarter-round or other shoe molding.  It's usually painted, so if you have to pull out the cable; a little calk/some paint, and you can't tell there was a hole.  IOW, drill at an angle into the top of the shoe molding.)
Actually, what the (bicsi certified etc etc) pros do in this situation is install premise cabling and hardware(jacks).  So instead of putting a male plug on it, use solid core CAT5e and terminate per 568A onto a jack, mounting the jack into a biscuit or wall plate as fits your situation.  This is preferable as the mounted hardware tends to stay still and keeps your pain-in-the-butt-run cable from having issues.  Then a patch cord goes from the jack to your machine.  When the patch is crushed, chewed or otherwise destroyed by furniture pets or toddlers, it's easily replaced and your intra-wall cabling is untouched. 

All that said, this is definitely going for what my mom calls "the nth degree" of reliability. Great and even necessary for an enterprise network, less important for a 3 node home network.  So it's a judgment call.  I'd spend the extra $15 on jacks and stuff if you make a living off it and need it to always work.  But I'm kinda anal about these things, which is why my mom has phrases like "the nth degree" in her vocabulary. 
How is using a hand installed socket any better than using a hand crimped end? I do both, and so long as you're careful and know what you're doing, they'll both turn out just fine.
.  Re-read the comment.
.  Rocketguy's method allows one to easily replace the last few feet of cable (the part that gets the most abuse) instead of messing with the premise wiring. Not necessarily better (each connection introduces some noise/attenuation), just more convenient.
Like others have said, there's no reason a cable hand-crimped is any worse than a factory made cable, just pull out a multimeter and test it before you install. I know that I trust the connectors on a cable I made more than factory-made cables, but I don't trust others to do such a good job. (if it's low-quality wire, and they go bad; that's a separate issue). Of course for a 60,000+ node network, it's impractical to hand-crimp all of them.

However, I would like to note that flat satin is okay for cables shorter than the minimum length of cat5.
1) Hand crimped can work, but it is not as consistent as a quality cable made via machine. I've worked with those machines personally, so I understand some of the differences that actually do exist, in terms of repeatability. I have done both, and while it's appropriate to hand crimp to expedite the occasional connection on your own home network, it shouldn't be a regular professional practice for network installation at the enterprise level. Also most hand crimpers are crap, which may be most of the problem. 2) Flat satin is "CAT-0", no twist at all. It's an antenna for any EMF in the area, and should never be used for network cable. Again, it can be made to function, you could use two car jumper cables and pass traffic, but what you'll end up with is more network errors and a slower network. I've seen this firsthand, and done packet analysis to back it up.
Let me tell you a little something about those "factory cables" you are recommending. I have worked on the commercial building installation side of things where nearly ALL the crimps are hand done, and I have also worked on the "factory" equipment.

To begin with they are about 6 to 8 times more expensive then DIY ones. They only come in predetermined lengths that are generally rarely suitable for the application unless the application has been specifically engineered for them. Next the failure rate for the "factory made" ones is one out of one hundred... about the same as a home crimp... why? because the dies wear, insulation doesn't cut right, wires snap, etc... the reason why the factory ones *Seem* so good is that they are tested before packaging. Even there the tests are quick continuity tests. Only about one in a hundred are sent to QA to be thoroughly tested.

On the home use side, I actually have to have a stash of several different lengths in order to find one that will match and don't get me started on longer runs. If you get the proper tools and a tester there is no reason why a DIY crimp can't be every bit as good as a "factory" crimp. Especially if you make several short practice cables to get the feel for doing it.

Maybe you have the nice deep corporate budget and regimented installation where factory crimped cables turn out to be easier but the average Instructables user does not have that luxury.

Finally, this is an expedient that is especially useful for field work and for low stress applications where the wiring only gets disturbed occasionally. I have had the clips snap off the ends of a perfectly good cable several times when trying to reroute the cable and this "fix" is an excellent idea.

Getting factory made whenever possible is a great idea because you have the option of returning it to the place of purchase if it fails out of the box. However, DIY can be done every bit as well if not better if taken the time to do carefully and properly.
cegu rocketguy5 years ago
There is no quality or reliablity diffrence betwen your cable or factory cable, if any, yours is better. All the phones all over the world work on cables with man-put connecters on them, factory cables are minority. Tester? A battery and one LED is your tester. It's just a copper wire, nothing more. No need to compare it with oil quality.

abadfart5 years ago
very nice but i prefer the crimper but in a pinch i bet you could do with a cople of screw drivers  
Perhaps, but I'd think you would just screw up the connector. You don't just crimp down on the main cable; you must also drive the metal pins into the individual wires. While it could be done, I bet you'd mangle the plastic around them if you weren't super careful/lucky.
ya if you had a really small one and a bigger one it might work
lukeshu lukeshu4 years ago
I stand corrected: http://www.instructables.com/id/How-to-crimp-a-Network-Cable-with-a-Victorinox-Swi/
Very nice idea! I've just tried this with the Ethernet cable that came with my Xbox 360 and it doesn't work too well because it's one of those Ethernet cables with a large connector 'housing' like this:

http://img14.imageshack.us/img14/7649/41ofkhmf2alss500.jpg

Is there a way to fix these types of Ethernet cables? Thanks.
Cut the end off, and put a new connector on? The connectors are cheap, but you need a crimper which isn't.

Else, just shave off the plastic?
hhhttt4 years ago
isn't it called internet
lukeshu hhhttt4 years ago

Strictly speaking, both bmlbytes and crazytrain320 are wrong.

From the bottom up:

The connector being repaired is an 8P connector, specifically an 8P8C. This is often incorrectly called an RJ-45, which is actually a 8P2C connector that was once used in telephone wiring, but didn't catch on.

The cable itself is UTP (Unshielded Twisted Pair). Depending on quality, it is either category 5, 5e, or 6 UTP, or just `cat5' (or 5e, or 6) for short. Ethernet refers to standards for the layer 1 (physical) and layer 2 (data-link) layers of the OSI model. Modern versions of Ethernet are part of the IEEE 802.3 standard.
Most modern versions of Ethernet specify that layer 1 be the combination of an 8P8C connector with cat5 UTP or better cable.
Ethernet at layer 2 defines LAN-level transmission and addressing (MAC address).
An ``Ethernet cable'' therefore refers to a cable that is cat5+ UTP with an 8P8C connector at each end.

The TCP/IP protocol stack refers to a protocol stack (more than just TCP and IP) that starts at layer 3 of the OSI model, and extends into the upper layers. TCP/IP is designed to run over Ethernet (although, this isn't strictly necessary).

The Internet is a worldwide TCP/IP internetwork.

I hope this was informative.
bmlbytes hhhttt4 years ago
Ethernet is the proper word in this case. Ethernet is used to describe the physical connections between internet enabled devices that use the RJ-45 plug. RJ-45 is the plastic plug at the end of the cable (the part that had the clip break. To be more technical about it, this cable would be referred to as Catagory 5, Catagory 5e, or Catagory 6 cable, depending on the quality.
Ethernet is a kind of cable to connect you to the intranets

Buy a crimper. Replace the RJ45. It works.
i did this. it didn't click though. but it works as a way to wedge the plug in there. can you use zip ties that are rounded?

One of the clips on a cable of mine broke and I had read your instructable before but I remembered the basics so I was able to experiment and get it to work.
emattrose4 years ago
One time when I was at a robotics competition, there was an accident and an ethernet cable got ripped out of a laptop. Unfortunately the clip on the cable didn't break, something inside the port did, so no cables would stay in place. We had to rig up a velcro harness to hold the cable. I hope that next time something goes wrong the clip breaks instead, so we can use this brilliant solution.

GREAT Hack. I destroyed one of my good cables to give this a spin. It works like a charm!  Thanks!
laxap (author)  bunnydeath4 years ago
It is quite unusual to hear a feedback like I broke my stuff just to test your trick... ;-)

I'm glad (and relieved) that it worked for you. Thanks.

 That... Is unusual... Still, with a bucket of cables this is appericated.

 Hey it works pretty well. Used it on 2 different cables. A little disappointing turnout but hey, it's better than nothing =)

that is insanely awesome, I mean, seriously, seems like a simple fix but nobody did it before, and the fact that you came up with makes you a macgiver :P, congratulations and thanks for the awesome instructable.

This is amazing! It actually made me consider breaking all the locking tabs in the house and replacing them.

Seriously? You should try with just one, first...

When I buy a cable tie pack, what is meant with the dimensions 35x100mm?
Is 35mm the head width or the cable width?
I not sure which to buy.
Thanks
laxap (author)  koraygumbur4 years ago
I had a whole bunch of cable ties of various sizes, and was lucky to find the proper size. That said I understand that having to go purchase the right ones can be tricky.

35mm would make really *huge* heads. Mine have 4.3mm wide heads, and are 100mm long. My pack's label reads 100mm 50pc, so maybe your 35x100mm means 35 pieces of 100mm long... 100mm sounds good.

The best would be to be able to measure the head with a caliper.

Good luck!

thx
dont suppose you have any other idea how to fix this? maybemake it out of icecream lid or something?
i dont have any zip ties atm, besides the ones inside my computer
You could cut off the plug and crimp on a new one
What kind of netbook is that?
laxap (author)  Yerboogieman5 years ago
It's an Acer Aspire One, with flash disk and Linux.

We happen to have a few (ton) of these around the shop, I should try this.

This is exactly what used to make instructables great.  But now many of them just aren't that useful.  Thanks for being relevant.:) 
twocvbloke5 years ago
I stick a bit of double-sided tape on the tip of the plug and shove it in, works great but it's only a temporary measure, blu-tak is a more permanent solution though... :P
knexfan91825 years ago
I would try it if i had a broken ethernet connector tap.
Nice. I have one that doesn't stay plugged in on the back of my computer but it still has the clip. I'm not sure why it doesn't stay.
Try clipping a bit off a pen spring and jamming it under the tab, it did wonders for mine
i could try that thanks.
laxap (author)  the_burrito_master5 years ago
Maybe the clip's junction to the plug body has become weak. I'd stick some foam between them to give back the spring effect.
Nice trick
Just sorted out 1 broken catch.
Using a piece of cut up zip tie that was on the floor after unpacking something recently & a new zippy that came with some hardware ( as I don't carry a stock of zip ties!) this killed 2 with 1 stone, all that went to waste was the piece of  cut zippy pulled out of the 1 from the floor.

Although if one owns a zip tie tool (optional), one will most probably have the RJ45 jack press too. But still a great instructable.

AWESOME I have a friend who has a broken cable. Cant wait to try this out. :)
nice instructable...nice emergency repair...while i'm on the go otherwise i would just crimp a new connector...i see you have the acer aspire one!!!the netbook i'm using now!!! anyway nice instructable!
laxap (author)  milo0is0hot05 years ago
Thanks. I'm just loving this Aspire One (Linux w/ 4GB flash). Must find the time to install an Ubuntu distro on it...
yeah i have the 8gb ssd one (i think you have that as well) with linpus light linux...i upgraded to a 60gb hard drive with 1.5gb of ram...i now run xp and ubuntu!!! ubuntu installs with ease...althought i have installed it inside xp...so it can be easily be deleted...also i just got a new 9 cell battery for £36 from ebay and my battery lasts over 8 hours!!! much better than the 1.5hrs that i got from the standard battery...they also do a 12 cell battery which would probably last over 10 hours!!! all good!!! i'm still loving my aspire one after a year!!!although the screen is a little small...

All good for the cable end. My problem is the female end. Some fool broke the jack on my computer. Don't have the guts yet to open it up and see how "replaceable" that end is. RetiredLawman
ajparag5 years ago
great idea! i have a broker Ethernet cable too... m surely going to try it. thanks keep posting great ideas
Seems like more work than just recrimping the RJ-45. You can throw a boot on there too so it won't break off next time.

Ulyssys5 years ago
This is a great fix. Replacing a RJ45 plug can be challenging for someone, like me, who doesn't do it often. Replacing with a new patch cord is not an option if you are working with a long run. My experience with replacing a RJ45: I bought a $10 crimper that lasted for 3 connectors. Bought a better $27 crimper that works great. Buy EZ-RJ45 connectors, by Platinum Tools (15 for $10). The wires run through the connector, so you can check your pattern before you crimp. I cut the wires off square, and close, with a good wire cutter, pull it back just enough to protect the ends, and then us the crimper. Platinum makes a crimper that crimps and trims at the same time, but will set you back $50 to $80, depending on the model. I should have bought it the first time.
hypercube335 years ago
Really the tools to replace the entire thing are cheap. $10 grabs you a bag of plugs, a stripper and crimp tool. Grab some no-snag cables and the clicky isnt going to break off.
One thing to consider is the type of wire you are handling. Twisted pair obviously, but is it solid or stranded? The crimp-on RJ45 connectors are better suited for stranded wire by design. The solid wire is used for port to port connections installed within the walls using patch cords (the more flexible stranded cat 5). The solid wire should be "punched-down" on a patch panel and a "punch-down" style connector - a punch-down tool with a 110 blade is about 60-85 bucks. The adventurous type however, may consider using the back side of a razorknife with an appropriate sized blade.
amplex SpdBmp245 years ago
Do not attempt to punchdown to 110 or 66 blocks with anything other than the cheapest punchdown tool ($10 off ebay)!!! Bad things will happen if you are using an older PBX phone or older equipment which carried a heavier voltage. It won't kill you, but I can't say how many times I was shocked on my first nightmare attempt @ punching down without a punchdown tool (when I was starting out on my own). Plus the fact that I brought an old Premier phone system to its knees and lost a whole stores phone routing (phone ringing thru to intercom and every location), but this was the fault of the CMOS battery in the old premier system being dead, and not saving the routing information after I blew a slowblow fuse from some 66 block buffoonery. Save yourself the hassel and buy a freakin punchdown tool before you attempt it with something else!!! Also, I have punched down stranded core to 66 blocks for my whole career (2 yrs) and never had a problem/complaint. All I use is stranded core UTP.
laxap (author)  hypercube335 years ago
You're very right, the crimp tool & co is the professional solution. And the zip ties, coolness, guerilla DIY -- much what instructables.com is about, right?
Oh indeed. In a pinch with only zip ties and a few other tools, I'd totally do this. I just cant see people who have like 50 cables would go and do this esp as a professional, it seems too tacky to me =)

They should have really designed the plugs this way in the first place (reverse clip) as it cant really be ripped off, just bent off, so pulling on the cable wouldnt hurt it, and it wouldnt snag or tear off moving the cable through a switch mess. =)
someone should market cable ends like that because I hate the no snag cover things and am always breaking the clips off.
$60+ plus another $15+ for the crimper and parts vs 300+ Zap Straps in the cupboard.....(and the chance to show off what they can be used for)...I'll go with this Great Instructable!
SPORTcoupe5 years ago
Slick, very slick. Definitely innovative. Great job.
I have always thought that the clips on ethernet connectors should come from the cable toward the port instead of from the port toward the cable. That would prevent them from snagging when they are pulled threw a tangled mess. Instead, the makers have created a dozen or so different protective boots. LAME!
And the protective boots are a pain in the butt to unplug at times (in small spaces). I feel your pain, I've had a few of the clips break off rerouting cables through cashwraps etc. The best thing you can do is be gentle pulling them. Having the clip come from the cable end would alleviate this problem, wonder why no cable manufacturer has ever implemented this. (To sell more cables? =)

I'm getting my networking stuff set up in a new room in my house and realized many of my cables are missing one or both fastener clips, so I couldn't use them without fear of them falling out. I was honestly planning on buying a bulk lot of ethernet cords on eBay this weekend, but then I came across this. Thanks tons!
hugmann5 years ago
Excellent solution for the broken tab. I'm in charge of several laptops during the tax season. The tabs on the cables are fine but the little tabs on the laptop that hold onto the tab on the cable have broken. Our solution, duct tape. I'm looking for a solution that doesn't mean replacing the jack.

infargo5 years ago
Don't squeeze the cable too hard... esp plenum rated wires. wires inside can be compromised over time (teflon is soft) SpdBmp24 has a point, but you can get RJ45s for either stranded or solid wire. There is a "universal" connector, but it doesn't work very well with either wire type.
Barts5 years ago
Nice, now I finally know why I kept all these broken cables around ;-)
jridley5 years ago
This is a pretty cool idea. Of course, $10 at Deal Extreme buys the crimp tool that will also do phone connectors,and they have the connectors for $2 for 20. Then you can not only repair broken cables but make custom length cables, which I find very useful for keeping things neat - no need to use a 5 foot cable to get between 2 ports on neighboring switches/routers, etc.
deeeveeeg5 years ago
Nice idea and well done Instructable. I've replaced a lot of cable ends too, but with a cat3/5 crimping tool. Many a time I could have used this idea to keep a network happy until a"real" cable were available..

mistere3275 years ago
I was told years ago that when these types of plugs (RJ-11, RJ-45) were designed (by some folks at Western Electric) they worked to a specification that required the connector should withstand 50 insert-remove cycles. This repair might well last longer than the original!

The thing I really like about this is that the repaired cable is actually more robust than the old one: there's no way the replacement locking tab can get torn off when pulling the cable through a rat's nest of cables. Top marks!
