ABSTRACT:
An arrangement for mechanically and electrically coupling a heavy gauge wire, which may be a multiconductor wire, to a conductor lamination of a circuit board. The circuit board is provided with two substantially parallel slots extending inwardly from the edge of the circuit board and on either side of the conductor lamination. A clamping cage which is formed from a strip of sheet metal to have a substantially box-like configuration has two lateral portions which engage the substantially parallel slots. Two contact plates are arranged on respective sides of the circuit board and within the clamping cage. The contact plates are each provided with laterally extending tabs which bridge the slots. The clamping cage is provided with a contact portion for securing the heavy gauge wire to the contact plate on the conductor lamination side of the circuit board. The other end of the clamping cage is provided with an engagement portion which, in one embodiment, engages with a screw which is forced against the other contact plate to secure the clamping cage and the wire firmly to the circuit board. In a further embodiment, the conductor lamination extends beyond the slots, and electrical contact is made therewith via the laterally extending tabs of the contact plates. In embodiments where both sides of the circuit board are provided with conductor laminations, through holes may be provided in the region intermediate of the slots, which holes are metalized. Also, the edges of the slots may be metalized to provide electrical communication between the conductor laminations. The laterally extending tabs distribute forces which would otherwise bend the region intermediate of the slots to the remainder of the circuit board.
