Many transceivers have RJ45 connectors on the microphones and many of them broke at transport or even in the storage box when searching for stuff.
I do have a well equipped laboratory with all kind of stuff, including the proper tools to repair a broken RJ45 but... I do have a problem with colours! Yeah, I barely can distinguish between red and green, at least the red and the green used in wiring. And in resistor code. Traffic light pose no problem, I can see that green and that red so, no worry with me on the streets at the same time with you, HI.
So, I thought myself it's better to prevent than to cure (this came with the age, probably) so I searched for a quick, cheap and reliable solution to protect that little shit tab.
An ideea popped out from the void and here I am, making protective caps from some piece of heatshrink tube.
Find a suitable HS tube, put the connector inside it; the HS tube has to overpass the tab with around 3mm not more!
Then gently apply heat observing the molding. When it wrap the connector stop heating and cut the useless part outside the connector.
After that, gently move the HS tube to extract the connector.
And this is all...
I suggest to use a dummy RJ45 or some kind of ethernet cable as a jig.
Do not heat the HS tube with the real RJ45 inside, you may mess it up and cry a lot.
