Abstract
Abstract The invention comprises an apparatus especially adapted for connecting hermetic compressor motor leads disposed in a cluster to a hermetic shell-mounted terminal of the type having three closely spaced pins with flat tabs thereon. The cluster assembly includes a block with cavities therein in an orientation in which the contact sockets are relatively flat and disposed at equilateral angles to each other so as to align with the tabs on the pins and so that the contact wires extend in a pinwheel arrangement at the edge of the block. An additional socket is provided in the block for reception of a thermal sensitive device that provides overload protection for the compressor motor, with the thermal sensitive device wired in series with one of the wires of the pinwheel arrangement.
