Abstract: A novel electrical connector structure having integrally molded plastic construction with a first premold core and a second integrally molded external shell separated by metallic foil or stamping. Plastic spring-clips of integral plastic formation are also provided with dual notches thereon one for direct engagement with a matching connector and the other a mounting panel or bracket. Concurrent connection of the connector to a matching connector and to a panel or bracket is made possible in which the matching connector is independently attachable or detachable from the connector with respect to said panel or bracket. The spring-clips are of such a compressible configuration such that when compressed the spring-clip deforms or deflects from its original configuration, and upon release of external pressure, it tends to revert back to its original disposition.
