Banana jacks / binding posts on PCB
(1/1)
joeyjoejoe:
I want to get some binding posts on a PCB but I have no clue what to do.
At first I thought I'd go with a Cal Test 2232 ( http://www.caltestelectronics.com/documents/Cal_Test_Cat_No_23.pdf ) but I'm not sure if that will work.
The cheap fabs have ~6mm maximum hole size. But, is this for plated through holes? Can I just drill/mill any 'ol size hole pattern I want, and put some copper around that hole on the surface that makes contact with the nut, which holds the binding post?
This is for extremely low current, but it would be nice to know in general what is the practice.
Jwillis:
If your mounting directly to the board the hole size only needs to be a wide as the threaded pin and just nut it directly to the copper.Or you can do something like this. https://learn.sparkfun.com/tutorials/benchtop-power-board-kit-hookup-guide/all or if you need it to be 90 degrees https://www.chk-electronics.com/PCB-Mounting-Terminals/ or these https://www.walmart.ca/en/ip/Replacing-Binding-Post-PCB-Mount-Banana-Socket-4mm-2-PCS-for-Audio/PRD3NJFROMQSL5F
You don't need to get them from these guys but it gives you an idea of what can be done.
