What connectors

Post by daryll » Fri Feb 19, 2021 10:43 am

A number of PCB`s have connectors to conect Pots , jacks etc , could some one tell me what these are , for example .....

Depends on how you choose to connect to it. You could just solder to the pcb, omit the part but then you would have to desolder to remove it.

So your illustration looks sort of like a screw terminal but I've never done it that way.

Advantage is no connector needed. Disadvantage is I get the feeling a wire might wiggle free too easily.
Maybe I'll try this way next time. I'll mention other ways I've actually used...

Pretty sure that's 2.54mm spacing between holes, so ALTERNATELY you would need a header with that many pins with 2.54mm spacing (pretty common) and then a connector to build a cable for.

I used these the first time I built PCBs like that. The advantage is there is a locking tab to hold it better. Disadvantage is you have to crimp and build a connector to plug into it. Watch where the tab is and you don't build your cable backwards, I shorted a yusynth pcb once because I mounted the power header in reverse and had the cable made the right way (so the header guided my cable in reversed)

you look at a link saying "people often buy along with" to find the connector

Another ALTERNATE way is this.

Advantage is you can buy those hobby arduino pin cables instead of building a cable with a connector. cut them in two, solder the wire to the pot or jack. Disadvantage is they pop out and are separate. Have seen multi pin versions but I never find the right ones and just use separate single cables cut in 2.

or go the opposite gender
you can get male or female cables so this would work with female cables and a male header on the pcb

advantage is these snap apart cleanly to be whatever length where as the female pcb headers need to be the right pin count though you can break them winding up with a messy result and sacrifice a pin.

I'd suggest buying these pre-assembled cables to solder to the pots, and the matching connectors from the same place. As you can see they are a few pence each and if you're plug and forget they won't wear out.
