ABSTRACT:
Circuit board terminals suitable for coupling high voltage, high current wires, such as 240 volts, 50 amps, to a circuit board is shown in which for each wire a block 24 of electrically conductive material is formed with a pair of ribs 48, 50 which interfit with a corresponding pair of slots 54, 56 in the circuit board 12. A bore 40 formed through the block from one sidewall to an opposed sidewall is adapted to receive the high voltage, high current wire which is clamped against the block by a set screw 44 received in a threaded bore 42 which communicates with the bore extending between the sidewalls. Another threaded member 60 is received through a bore 58 in the circuit board disposed between the two slots and into a threaded bore 62 in the bottom of the block disposed on one side of the circuit board with the head 62 of the threaded member engaging the high voltage, high current trace 22 or 14 on the opposite side of the circuit board. A layer of solder 68 is then placed over the head and onto the trace.
