Abstract: By providing a cover member which is pivotally mounted to the base member and is constructed for being automatically securely affixed to the base member by frictional and locking engagement therewith, an efficient, easily manufactured and easily assembled conduit/cable connector is realized. In addition, the cover member comprises a pair of gripping fingers constructed for engaging and holding a flexible metal conduit and/or armored or metal clad cable. As a result of this construction, the operator is able to quickly and easily insert a flexible metal conduit and/or armored or metal clad cable into the gripping fingers of the cover member, and then arcuately pivot the cover member and the engaged metal conduit and/or armored or metal clad cable into the precisely desired mounted position with the base member.

Abstract: An electric connector assembly disclosing various embodiments, each of which includes a connector body having a frustro-conically shaped outlet end portion that converges toward the outlet opening and having a complementary frustro conically shaped retainer ring circumscribing the outlet end portion wherein the retainer ring is integrally formed with a locking tang and ground tangs arranged to be snap fitted to a knock-out hole of an electric box. The latest embodiment includes a frustro-conical retainer ring having an auxiliary tang arranged to permit the connector assembly to be obliquely inserted and locked to a knock-out hole of an electric box using a minimum of applied force for effecting a snap fit connection to both lock and electrically ground the connector assembly to the electric box and a method of installing the associated connector body to an electric box.

Abstract: Various embodiments of electric connector assemblies, each of which includes a connector body having a frustro-conically shaped outlet end portion that converges toward the outlet opening with a complementary frustro-conically shaped external ring circumscribing the outlet end portion wherein the frustro-conical retainer ring is integrally formed with a locking tang and electrical grounding tangs arranged to be snap fitted to a knock-out hole of an electric box, in combination with an internal unidirectional snap-fit wire conductor retainer disposed in the inlet end portion of the connector body to facilitate the connection of a wire conductor to the connector body and whereby unintentional separation of the wire conductor therefrom is prohibited.

Abstract: An electrical connector that includes a connector body having an inlet end and an outlet end that slopes downwardly toward the outlet opening that is circumscribed by a complementary frustro conical outer snap-fit retaining ring mounted on the outlet end of the connector body. The outer frustro conical retaining ring is integrally formed from a blank of spring steel having integral locking and grounding tangs blanked or formed out of the plane of the blank. The connector assembly also includes an internal sleeve having inwardly formed spring fingers to secure an electrical conductor to the inlet end by a snap fit. In an alternate embodiment, a simple clamp arrangement is substituted for the internal snap fit sleeve for securing a wire conductor to the inlet end of the connector assembly.

Abstract: By providing a continuous, elongated strip of material, which comprises an arcuately curved section in combination with at least one flange section extending outwardly from the curved section, an efficient, easily manufactured, and readily installed protector shield is realized. By employing the shield construction of the present invention, any desired tube, pipe, conduit or cable, such as a non-metallic electrical power carrying cable, is capable of being completely surrounded by a protective shield which is affixed directly to any support wall, such as a concrete or cinder block wall, with both ease and convenience. In addition, numerous other tubes, cables, and conduits, such as water carrying tubes, low-voltage cables, signal carrying cables, and other utility tubes, pipes, and conduits are capable of being similarly protected.

Abstract: A connector assembly for securing an electrical conductor to an electric box which includes a metallic connector body having an inlet end portion and an outlet end portion with a frustro-conical snap fit retainer ring circumscribing the outlet end portion of the connector body. The frustro-conical, snap fit, retainer ring is formed from an elongated blank of spring steel material having integrally blanked out of the plane thereof a series of holding tangs bent outwardly from the plane of the ring with one or more grounding tangs disposed in co-planar relationship relative to the surface of the frustro-conical ring, whereby the outlet end of the connector assembly can be readily inserted through a knock-out hole of an electric box for securely locking the connector assembly to an electric box and insuring a positive electrical grounding effect.

Abstract: An electric connector assembly having a connector body defining an inlet end portion and an outlet end portion interconnected by a through bore wherein the outlet end portion is provided with a tapering frustro conical surface that is circumscribed by an external retainer ring of a frustro conical shape complementing the frustro conical outer surface of the outlet end portion. The conical external retainer ring also includes locking and grounding tangs arranged to effect a snap fit connection of the connector assembly to a knock-out hole of an electric box or panel. The electric connector assembly further contemplates the use of internal wire conductor retainer associated with the inlet end portion so as to effect the attachment of an electric wire conductor thereto with a snap fit in a manner that prohibits any unintentional separation of the electric wire conductor therefrom.

Abstract: By providing an integrated base member and cover member, with the cover member being easily arcuately pivotable along one edge and easily fastened to the base member along the opposed edge, an easily manufactured and easily assembled conduit/cable connector is realized. Furthermore, by employing the conduit/cable connector of the present invention, any desired flexible metal conduit and/or armored or metal clad cable is quickly and easily secured to the connector for mounting thereof to an outlet box or junction box at right angles, with complete assurance that the entire mounting operation can be achieved by a single operator quickly and easily.

Abstract: An electric box assembly that includes a box extender having a tubular body with opposed sides arranged to be received within an electric box, and which box extender is formed with a pair of laterally outwardly extending face flanges arranged to be flush mounted against a wall surface in the assembled position. The box extender is devoid of any top or bottom flanges and is adapted to be secured in place within an electric box by the electric device, outlet receptacle, switch or the like. In an embodiment of the invention, the sides of the tubular body are tapered inwardly toward the central axis of the tubular body so as to permit the box extender to be nested one within the other to facilitate shipping and handling.
