Abstract

Abstract An improved electrical cable connector combining the benefits of a positive securement of an electric cable wire with a connector element that is detachably engageable in snug-fitting electrical transmitting connection with a takeoff spring-type connector element. The cable connector includes the application of an operable securement and coupling to place such connector elements in the electrical engagement and to so retain the same against accidental displacement until the operable securement is released to thereby permit the connector elements to be detached.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 357 words
An electrical cable connector comprising a body, first and second detachably engageable electrical connector elements, the first of said elements being a coiled spring pressure contact member mounted on said body, the second of said elements being movable relative to said first element for detachable electrical engagement therewith, screw means on said second element threadedly engaging and securing a cable to said second element, operable securing means cooperating with said body to secure said first and second elements in engagement with each other, couplinG means between said securing means and said second element to move the latter into non-detachable electrical engagement with said first element upon one operation of said securing means and to enable attachment of said first and second electrical elements upon another operation of said securing means, said body defining an essentially closed end sleevelike housing with said first connector element being mounted in said body at said essentially closed end and having an opening defined therein, an electrical take-off member on the exterior of said body extending through said defined opening and electrically connected with said coiled spring, said operable securing means and said body each having cooperable thread means for relative threading and unthreading movement, said second element being a male plug of a cross-sectional size greater than the interior opening of the coiled spring to cause the same to expand in engagement thereabout to assure snug electrical engagement between the surface of said plug and the coils of said spring, a narrowed portion on said plug into which the coils of said spring relax, said plug having an axial opening in which the electrical wire of a cable may be received, said screw means being a set screw for engagement with the cable wire to retain said plug and cable joined together, said coupling means being a sleeve movable along the cable, cooperable engaging means on said male plug and coupling means to force said male plug into electrical engagement with said coiled spring upon the one operation of said securing means, and means on said male plug to axially compress the coils of said coiled spring about said male plug.
