ABSTRACT:
A push-in type pressure lock terminal for electrical receptacles wherein the bared end of various diameter sized conductors may be inserted into a recess in the receptacle for connection with the internal conductive element thereof, and which is then held therein by a restraint element against withdrawal until the restraint is released. The restraint element comprises a double-action cantilever spring integrally formed from the internal conductive bus element of the receptacle. The double-action spring deflects over a relatively wide range within a limited space within the receptacle to thereby accommodate a range of various diameter sized conductors without causing an objectionable permanent set to occur in the spring. The cantilever spring produces a double-action deflection in the direction of insertion when a wire conductor is inserted and bears against such free end. The wire conductor is inserted until the free end of the spring deflects enough to allow a portion of the wire conductor to extend past the deflected free end. The free end of the spring then bears against a first side of the wire conductor at an obtuse angle facing the direction of insertion and at an acute angle facing the direction of withdrawal until the biasing force of the cantilever spring against the wire conductor is released. The cover portion of the receptacle includes a depending wire guide portion which includes an arcuate bearing wall against which the second opposite side of the wire conductor bears when the cantilever spring is biased against the first side of the wire. The depending wire guide portion of the cover also includes a recess having a continuous bounding wall in which the end of the wire seats to prevent skewing and for positive alignment with the cantilever spring.
