I have a couple boards that I recently took the the AT Keyboard din5 connectors off to try and fix battery damage no keyboard errors. But sadly stress and battery corrosion broke the front gnd pins off.
I know those Pins are just GND pins and used to provide a bit of mechanical stress relief. but are they needed to be connected to provide GND to the keyboard or is the GND from pin 4 enough.
All the DIN5 connectors I see on ebay and Amazon do not appear to have the tin face but do have the pins.

thank you

AT (and PS2) keyboards have shielded cables that do use the metal ring to ground the shielding. There are some on ebay that have partial metal to do same electrically as the originals with grounding tab like this picture...
added: also on Digikey as SDS-50J part CP-2350-ND..
You should check to see if the old faces is tied to pin 4, if so you can use them, if not then probable should replace with one that is.

can you see if the outer shielding is connected to gnd pin ?
if so I think those might work ok

but... I think you should get new connectors
plugging in and out a DIN keyboard is really mechanically straining

Agree. Bothboards had so much battery damage under the DIN5 i wanted to make sure I could even fix them before wasting time ordering replacements. Good news is I was able to repair 2 out of 3 boards and am now waiting for New DIN5's. I ended up just soldering a bodge wire from the MB pin 4 to the shield. Not pretty but works to test.
