ABSTRACT:
A connector is described, which can be inserted into a hole in a base to securely mount therein while enabling removal and secure reinstallation. The base (14, FIG. 3) has a hole with an undercut groove (30). A connector mount portion (24) has a recess (42) that holds a snap ring (26). The snap ring has a gap that allows the snap ring to contract during insertion, and to then expand to lock into the groove in the base. An elastomeric spring ring (50) lies between the bottom of the recess in the mount portion and the radially inner surface of the snap ring, to prevent the snap ring from falling off prior to installation of the connector. The spring ring is readily compressed (at 50 in FIG. 8) when the snap ring is compressed during installation. A pair of contacts of the connector include vertical and horizontal portions (100, 102, FIG. 3) connected by a middle portion (110) that is bent at a right angle. The contacts are originally straight and inserted vertically into the connector, and then the top is pushed sidewardly to bend the middle portion against a corner portion (112) of the frame. Thereafter, a cap part (120) of the frame upper portion can be pivoted closed on a living hinge.
