Connecting wires on two sides (connectors)

[toiletmirror]

Hi, a little backstory.

I'm a university student doing a project that requires me to have a server inside a sealed chamber (vacuum).

The thing is the server's power-on button is connected to this little board here: https://imgur.com/z5oeJnS (beside my thumb) and this is the back: https://imgur.com/AfT74nC

It has 13 wires connected to each spot. Anyway, what I'm planning to do is to weld a KJL 15-pin d sub flange: https://imgur.com/OpJO1Vp (front) and https://imgur.com/HWw06rr (back) onto the wall of my chamber.

Then I would cut the 13 wires somewhere in the middle the length, soldering each wire to 13 of the 15 pins in a 1-to-1 positioning, with the little board/button on the external such that I can power on my server from the outside.

So before I jump into this, I'd like to ask for opinion, whether this is a good idea or not. I'm just hoping the 15 pins just work as a conductor from one side to another, and I'm not missing out on anything that may cause any short or open circuit. I'm just a mechanical engineer, and a student at that, so my experience with electronics is rather lackluster.

Thank you.

Electrically this will work as expected.

A standardf D-SUB connector, however, is not vacuum tight. You need to look into sealed conenctor specifically made for passing electrical conenctions through the wall of a vacuum chamber. E.g. like these.

An electronic circuit in a vacuum will overheat unless special measures are taken to transfer the heat to the chamber.

Hi. Thanks for the reply. Yes the connector will suitable.

So I could just connect any wire to any pin position, as long as I match the same piece (pin-position wise) on the external side?

Either way, here's a drawing for illustration of the setup: https://imgur.com/LtbLbCC

The chamber will be used for thermal management, so overheating is not a concern for me.
