ABSTRACT:
A shouldered connector pin socket (14) is shown having an open channel (14a) formed in the face surface of a wall member of a circuit breaker housing. An electrically conductive spring member (16, 16′) is received over the channel and is formed with a first set of spring fingers (16d) that are adapted to engage a connector pin along a first axial length (14c) of the channel making electrical engagement with the pin and urging the pin against the channel surface as the pin is slidingly inserted into the channel. The spring fingers urge the flange of the connector pin into a recess formed by a stepped shoulder defining the entrance to a second axial length (14d) with the stepped shoulder and the spring fingers cooperating to retain the connector pin in the channel. A second set of spring contact fingers (16e) can also be used to engage the connector pin along a third axial length (14e) and thereby provide a redundant contact system.
