ABSTRACT:
A basic connector body (13) which electrically connects and mechanically secures a ground wire (1) to a grounding member (14), e.g. pipe or electrical conduit, which body is made of a one piece brass alloy casting. The generally cylindrical, basic connector body has a smaller diameter, wire section and a larger diameter, pipe section, the size of the latter allowing the body to be slipped over the pipe end. In contrast, the smaller, wire section prevents the pipe from passing through the connector body due to the presence of a ridge (7). When the connector body is slipped over the end of the grounding pipe until the end of the pipe bears against the ridge, a first set screw (8) is screwed down until it drives itself down against the outer, exterior surface of the pipe, electrically connecting and mechanically securing the connector body to the pipe. Preferably after the connector body is secured to the pipe, the wire is inserted into the interior of the connector body until its end is at least past a wire set screw, threaded opening (4). Once the wire is properly positioned within the interior of the body, a second set screw (5) is screwed down until it contacts and drives itself down against the wire, securing it against the opposed, interior of the wire section, causing it to also be electrically connected and mechanically secured to the body, thereby indirectly electrically connecting and mechanically securing the wire to the pipe, using the two, interiorly protected, set screw connections.
