Abstract: The present disclosure provides couplers used to connect one length of rigid electrical conduit to another length of rigid electrical conduit. The couplers include a body having a first coupling portion, a second coupling portion, a stop portion positioned between the first coupling portion and the second coupling portion, and a longitudinal bore extending from the first coupling portion through the stop portion to the second coupling portion. The longitudinal bore within the first coupling portion is a threaded bore capable of receiving a threaded end of a first threaded electrical conduit. The longitudinal bore within the second coupling portion has a diameter capable of receiving a threaded end of a second threaded conduit or an unthreaded end of an unthreaded conduit. The longitudinal bore within the stop portion has a diameter that provides a wire passage between the first threaded conduit and the second threaded conduit or the unthreaded conduit.

Abstract: By providing a single housing, component or element incorporating a plurality of passageways or receiving zones formed therein in cooperating association with a mounting ring or clamp constructed for being quickly and easily secured to a clamp, conductor or conduit mounted to an electrical box, junction box, meter box, or similar enclosure, an efficient, easily manufactured and easily assembled bonding bar or grounding bridge is achieved. Preferably, the plurality of passageways/receiving zones are constructed with each passageway or receiving zone cooperatively associated with a locking screw or set screw configured to enable grounding conductors to be inserted through the passageway/receiving zone and securely mounted therein. In this way, grounding conductors from telephones, cable televisions, satellite receivers, radios, television antennas, and the like may be inserted into the passageways/receiving zones and securely mounted in the desired position.

Abstract: A connector assembly having a slot aperture retainer ring for securing a connector body to an electrical box, with a slot adapted to receive a common tool, such as a screwdriver, to facilitate removal of the retainer ring from inside the electrical box. In one embodiment, the slot of the retainer ring is aligned generally perpendicular to a center axis of the retainer ring.

In an embodiment, a connector assembly has a connector body having opposed end openings provided with an outer surface that slopes downwardly toward the outlet opening. The inlet opening having placed therein cable retainer inserts. A sloping or frustro-conical, snap fit, snap in, or push in outer retaining ring with locking tangs is provided for snap locking the outlet end portion of the connector body to an electrical box or panel. Improved conductivity or continuity is obtained and a good electrical ground is formed between the electrical box and connector assembly.

Abstract: A connector assembly having an external retainer ring for both securing a connector body to an outlet box and also securing a conduit or cable from movement relative to the connector assembly. A multi-function retainer ring having a plurality of finger-like extensions or tabs with at least a portion of the extensions being inwardly bent. The inwardly bent tabs engage and retain a captured wire or conduit upon assembly. Other tabs function to engage an inner wall of a knock-out hole of an outlet box upon insertion of the connector assembly into the outlet box. A method of connecting a wire to a junction box using the connector assembly is also disclosed.

Abstract: By enabling two separate and independent solid or rigid tubing or conduits to be quickly and easily secured to a single connector for being mounted directly to a single elongated rigid or solid electrical tubing/conduit, an efficient, easily manufactured and easily assembled multiple conduit connector is realized. A multiple conduit connector is constructed for receiving two separate and independent rigid tubings or conduits and enables the two conduits/tubes to be securely affixed to one end of the connector while a single rigid metal tubing or conduit is secured to the opposed end.

Abstract: A connector assembly including a connector body with a locking cam defined on an external surface. In a method of use the locking cam cooperates with a perimeter of a knock-out hole into which the connector is to be inserted. During insertion of the connector body the locking cam engages the knock-out hole and deforms a retainer ring so as to permit further insertion. Once the connector body is fully seated, the locking cam cooperates with a locking tang on the retainer ring to hold the connector assembly together.

Abstract: An electrical connector assembly having a snap fit adaptor with bent grounding tangs providing improved electrical contact and enhanced grounding. An electrical connector assembly is adapted to snap fit within a knockout hole of an electrical box or panel for making electrical connections. A snap fit adaptor placed on the outlet end of a connector body has a plurality of locking tangs and grounding tangs. The locking tangs hold the connector assembly onto the electrical box, and a distal trailing edge of the grounding tangs extends into the knockout hole in the electrical box and are curved or shaped to provide a large surface area contact improving electrical continuity and providing enhanced electrical grounding. A safer more reliable electrical grounding connecting is made easily and without tools.

Abstract: This disclosure is directed to electrical connectors, and more specifically to various types of electrical connectors, including an connector assembly having an integrally formed connector body having opposed end openings provided with an outer surface that slopes downwardly toward the outlet opening. The inlet opening having lips that are crimped retaining cable retainer inserts. A sloping or frustro-conical, snap fit, outer, retaining ring with locking tangs is provided for snap locking the outlet end portion of the connector body to an associated electric box or panel. The frustro-conical retaining ring has grounding tangs engaging the inner periphery of a knock out hole of an electric box or panel for effecting a positive electrical ground therebetween.

Abstract: By providing a grounding conductor assembly affixed to a conduit bushing in a manner which enables the grounding conductor assembly to extend inwardly from the bushing, effectively being positioned coaxially with the inside diameter of the rigid metal conduit, conduit bushing is realized which enables all grounding wires to be quickly and easily mounted to the grounding conductor assembly. The conduit bushing of the present invention includes a generally circular shaped cover or cap member mounted to the terminating end of the conduit and incorporating an enlarged aperture which overlies the elongated passageway formed in the conduit. In this way, the electrical power carrying wires are able to extend outwardly from the rigid metal conduit into the desired outlet box, junction box with the grounding wire being quickly affixed to the receiving zone of the grounding connector assembly.

Abstract: By providing an electrical connector which comprises a single component capable of being inserted into the knockout hole of a housing of any electrical junction box, outlet box, meter box, or similar enclosure from the interior of the housing and securely affixed thereto, an efficient, easily manufactured and installed electrical connector is achieved which can be securely mounted to the housing of any electrical junction box, outlet box, meter box, or similar enclosure from inside the housing. The electrical connector/clamp comprises a generally hollow cylindrical shape incorporating an axial, longitudinal extending slot formed therein which terminates along the length of the electrical clamp/connector and forms the cylindrical housing into two portions movable relative to each other.
