ABSTRACT:
An auxiliary terminal block for an electrical switching device includes a molded block and at least one terminal for terminating the internal wiring and external wiring of the switching device. The molded block has a first wiring channel for the external wiring, a second wiring channel for the internal wiring, and a partial partition between the two wiring channels. The partition has a slot for engaging and locking the terminal after the internal wiring has been terminated. The partition may include two walls having a generally constant width therebetween. Shoulders or tabs may be disposed on each of the walls for engaging and locking the terminal to the block. Alternatively, the partition may include two walls which are at least partially resilient and which form a generally V-shaped opening between the two wiring channels. A shoulder may be disposed on each of the walls for engaging and locking the terminal to the block whenever the terminal is fully inserted within the partition. The terminal may have an L-shape, a first arm which terminates the external wiring, and a second arm having a crimp terminal or solder terminal for terminating the internal wiring. The first arm may have on opposite sides thereof two notches mating with the two walls. The two notches of the first arm form a neck which is generally freely insertable within the V-shaped opening and which is generally resisted by further insertion within the V-shaped opening until the neck is fully inserted and confined within an opening adjacent the shoulders.
