Introduction: Sugru Ethernet RJ45 Plug Protector

About: So many things to learn and make, so little time! I like things that are cool, useful, efficient, well crafted.

As you know, the locking tab of RJ45 network plugs breaks very easily. Protect it from breaking, with some Sugru. Prevention is even better than repairing a broken plug.

Then, when you pull the cable through a cables salad, the tab will not get hung to eventually break.

One 5g pack of Sugru will make approx 8 plugs.

Step 1: What You Need

In addition to the plug to be improved:
  • Sugru pack (5g, approx 8 plugs)
  • One toothpick (or a nail, a swiss army knife, ... or anything similar)
(In the next steps I will use a vise. It is really not mandatory.)

Step 2: Form and Place a Sugru Ball

Form a ball of the size of a big pea. Knead it for at least 30 seconds. Roll it.

Place it on the plug as shown.

Step 3: Stick It and Form It

Form it as shown to increase the contact surface with the plug.

Cover the tab by 1 millimeter. (Covering the tab more than necessary will make the plug difficult to release.)

Step 4: Press the Tab

Press slowly but firmly.

Step 5: Release the Tab

Unstick the tab, using the toothpick.

Press and release repeatedly, until the tab moves freely into its hole.

Step 6: Done

Let cure for 24 hours.
