The remote control for the boiler fall into the flor and one of the cables got disconnected from a connector. I don't know how am I supposed to put it back in, because the red seems to be really well placed, but I can't put the black.

This is the picture of the connector, and I would like to know what type of connector is it and also how to properly put the black cable in.

It's an insulation displacement type connector. It works because when the black wire is pushed into the "jaws" of the metal knife edges, it cuts through the insulation and makes an interference contact with the conductor inside the wire.

Normally a tool is used but you may be able to get a blunt instrument and push the black wire back into place. I'd probably solder it afterwards to ensure the connection is good BUT make sure the plastic case can withstand the heat without distorting.

  • \$\begingroup\$ @Nobita No, the knife edges (or jaws) cut through the insulation and make contact with the conductor. \$\endgroup\$ – Andy aka Apr 26 '18 at 11:42
  • \$\begingroup\$ Ok, so I need to push the black cable really strong so the edges cut the insulation. Oh man, I don't know what I'm doing :D \$\endgroup\$ – Nobita Apr 26 '18 at 11:43

    \$\begingroup\$ Try it - you've got nothing to lose. I regularly use a screw driver that has a blunt blade whose width is slightly less than the gap between the pairs of blades. \$\endgroup\$ – Andy aka Apr 26 '18 at 11:46
  • \$\begingroup\$ I am not able to push de black cable into the connector. What's the alternative? :D \$\endgroup\$ – Nobita Apr 26 '18 at 18:40

It looks like the red wire is pushed in from the side where the metal blades cut through the insulation to make contact and grip the cable.

Do the same with the black, trim off the exposed copper, make sure the hole is empty of debris and use something but thing to push the wire into place.

Don't forget to do a continuity test afterwards.
