I'm working on a connector design to use a piece of FR4 copper clad as the power connector on an HP power supply (it has a card edge exposed). This should give a large contact surface area vs the bolts I see people drilling through these. Plus, it's removable. The slots are for soldering power wires to the copper clad in place. The wires will come out the top. If this works, I'll add a fuse block on the side that takes automotive blade-type fuses. #diy_electronics #electronics
