Easy way to add "charging pads" to PCB/Case Assembly

Squad mind

Hi everyone! I'm working on a small battery powered PCB which will fit inside a small plastic "hockey puck" container. A number of these "pucks" will be sold together with a "charging doc" which will store and charge the pucks when not in use.

I'm trying to work out the best way to charge the battery. I'm thinking of having metal "pads" on the rr.com puck that pass through the puck's plastic shell and then make contact with the PCB on the inside, and having a similar system on the charging dock. I'm thinking of having SMD "contact sprints" mounted to the underside of the PCB and have these mate against metal pins that protrude through the puck, but it's the later of which I'm struggling to find. For a visual, think about "restaurant pagers" and how they charge.

    I would probably use something like a "pogo" pin on one side (top) that connects to a pad on the bottom of the next board.  Serious mechanical investigation needed but as you are aware it can be done.

    Look at this https://en.wikipedia.org/wiki/Pogo_pin
