How to unplug individual wire of PCB connectors

Post by dvojtise »

I'm new with RevPi and I wonder how to cleanly connect/unconnect the individual wires on the 4-pole PCB female connectors (Item No.: 200030) used on my DIO
For some experiment, I may need to change the wiring and I didn't find a way to unplug individual wires except by pulling "hard" on the wires.

The small orange plastic part doesn't seem to move :-/
Is there a trick (probably well known by industrial/pcb people ? )

Okay, use a screwdriver and then push in the orange tabs. The cable can then be easily removed again.
No ferrules are required for spring-cage terminals. However, if you do use them, it is best to use a self-clinching crimping tool.

Hi dvojtise, Here are instructions on how to open the housing - you may need to translate them into your language

Hi Dirk
I'm not speaking about the housing of the DIO module, but about the cables going into the PCB connectors (see attachment picture)

Is there a trick to remove cables from these connectors ?

If you're using ferrules (depending on the crimp pattern) it can be sometimes helpful to twist a little while pulling.

Ok thanks, that's it :-)
(I was miss leaded by the small hole next to the orange part, and trying to move it to that direction instead of pushing inward)
