I am looking for a robust 3 wire connector for delivering power from one circuit board to another. Both circuit board designs are malleable so there are no footprint design constraints yet.

There are three wires: GND, VEE, and VCC. I would like to have each wire carry a maximum of maybe 4A.

I usually use barrel type connectors for delivering power. However this is for delivering 3-wire power. Does anyone have any recommendations?

  • \$\begingroup\$ I don't have a good suggestion. The digikey link isn't much help and you've not said much, besides. So I decided to waste time in a different direction... For fun and until the footprint requirement arrives, perhaps consider this for tying one board to another. Meets requirements with some safety margin. The two inner "pins" for Vcc and Vee. The shields are GND. ;) \$\endgroup\$ – jonk Nov 22 at 5:13

    \$\begingroup\$ in the connecting cable internal to the case or external? \$\endgroup\$ – Jasen Nov 22 at 5:23
  • \$\begingroup\$ @jonk Thank you for the suggestion, seems a couple mils big no? \$\endgroup\$ – Jirhska Nov 23 at 16:15
  • \$\begingroup\$ @jasen The connecting cable really just as to go from one board to another, so internal I think? \$\endgroup\$ – Jirhska Nov 23 at 16:16
  • \$\begingroup\$ @Jasen rather than use two connectors I was thinking of using one connector for this. \$\endgroup\$ – Jirhska Nov 23 at 16:16

Without knowing too much about your application, let me dare to suggest you having a look on the Wire-to-Board MPC3 Connector family from we-online.com. It's good for 5A and comes in various combinations. Based on a crimping connection, you can easily connect or disconnect the plug into its receptacle on the PCB. It comes with an active locking system, which means you have to push a little lever to unmate your connection. Pitch is only 3 mm and you can go up to 250V.

If you are looking for a Board-to-Board solution, maybe LECO is a nice one for you.
