Abstract: A waterproof wire-sockets electrical junction cover suitable for use in wet environments includes a chamber to house the wire-sockets electrical junction. Sealable passages on one end of the chamber allow electrical wires to pass into the chamber. On the other chamber-end, a sealable port allows the wire-sockets itself to enter the chamber. The electrical wires are mechanically and electrically joined using the wire-sockets. The resulting junction is then drawn through the aforementioned sealable port into the chamber. The port is closed, thereby completely watertight sealing the wire-sockets electrical junction.

Abstract: A twist-on or wire-nut electrical connector having a rigid, electrically insulative upper body, a flexible, elastic, electrically insulative lower skirt, and a coil spring within the body for gripping wires which may be inserted therein. The provision of a flexible, elastic skirt allows the insertion of a larger number of wires (or larger sized wires) into the connector; the skirt further deforms to fit more easily within a crowded junction box or other high-density wiring environment.

In the preferred embodiment, the upper body is formed of polypropylene, the lower skirt is formed of a styrenebutylene compound or an olefinic thermoplastic vulcanizate, and the connector is constructed by multicomponent injection molding.
