Introduction: Sugru Ethernet RJ45 Plug Protector

Picture of Sugru Ethernet RJ45 Plug Protector

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

Picture of 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.

Nice advice. Unfortunately the releases still tend to break after some month if you plug and unplug the cable once or twice a day. It would be great if there is a solution for this.
