Telephone handset connector

Claim 2

An electrical connector comprising a receptacle body having electrical contacts therein and having a recess adapted to receive a plug, said body having a pair of flexible extensions therefrom constituting normally parallel walls with opposed shoulders spaced apart at a distance less than will permit ingress of a human finger between them, cam surfaces extending from each of said walls toward the opposite wall, a plug member having electrical contacts and adapted to fit in said recess, and a bifurcated head on said plug member, adapted to pass between said flexible extensions by outward flexing thereof responsive to coaction between said head and said cam surfaces as said plug is inserted into said receptacle, said head having cavities therein receiving said cam surfaces when said plug is fully received by said receptacle, allowing said flexible extensions to return to the normal condition.

Claim 3

An electrical connector as defined in claim 1, having a further set of can surfaces on each of said walls, inclined in directions perpendicular to the first mentioned cam surfaces, and coacting with said cavities in said head to flex said extensions outwardly when the bifurcated portions of said head are moved toward each other with the plug fully received in said receptacle, thus permitting withdrawal of the plug by tweezers or thin-nose pliers.

Claim 4

An electrical connector comprising a receptacle having a generally tubular sleeve portion for insertion through an aperture in a mounting wall, and having an enlarged head on the outer end of said sleeve to limit inward movement thereof with respect to said mounting wall, said sleeve having resilient wall portions capable of flexing inwardly, and latching devices on the exterior surfaces of said resilient wall portions for passage through said aperture by inward flexing of said wall portions, in combination with a plug received in the receptacle and fitting within said sleeve whereby upon insertion of said plug in said sleeve on said mounting wall, said plug extends beyond said mounting wall and latching devices and fits within said sleeve so closely as to prevent inward flexing of said wall portions to an extent which would release said latching devices from engagement with said mounting wall Adjacent said aperture.

Claim 5

An electrical connector comprising a receptacle having a generally tubular sleeve portion for insertion through an aperture in a mounting wall, and having an enlarged head on the outer end of said sleeve to limit inward movement thereof with respect to said mounting wall, said sleeve having resilient wall portions capable of flexing inwardly, and latching devices on the exterior surfaces of said resilient wall portions for passage through said aperture by inward flexing of said wall portions, in combination with a plug received in the receptacle and fitting within said sleeve whereby upon insertion of said plug in said sleeve on said mounting wall, said plug extends beyond said mounting wall and latching devices and fits within said sleeve so closely as to prevent inward flexing of said wall portions to an extent which would release said latching devices from engagement with said mounting wall Adjacent said aperture.

Claim 6

A connector as defined in claim 3 wherein said enlarged head has outwardly extending parallel wall portions defining a space therebetween conveniently accessible only to narrow tools such as the jaws of thin-nose pliers, and said plug has an outermost head portion normally disposed between said wall portions when said plug is fully received by said receptacle.

Claim 7

An electrical connector comprising a receptacle having a generally tubular sleeve portion adapted to be inserted through an aperture in a mounting wall, and having an enlarged head on the outer end of said sleeve to limit inward movement thereof with respect to said mounting wall, said head having outwardly extending parallel wall portions defining a space therebetween conveniently accessible only to narrow tools such as the jaws of thin-nose pliers, said sleeve having resilient wall portions capable of flexing inwardly, and latching devices on the exterior surfaces of said resilient wall portions adapted to pass through said aperture by inward flexing of said wall portions in combination with a plug adapted to be received in the receptacle and to fit within said sleeve so closely as to prevent inward flexing of said wall portions to an extent which would release said latching devices from engagement with said mounting wall adjacent said aperture, said plug having an outermost head portion normally disposed between said wall portions when said plug is fully received by said receptacle, said outermost head portion of the plug being bifurcated, and said parallel wall portions and said outermost head portion having coacting latch means which latch means is releasable by moving the bifurcated parts of said plug toward each other.

Claim 8

An electrical connector comprising a receptacle having a generally tubular sleeve portion adapted to be inserted through an aperture in a mounting wall, and having an enlarged head on the outer end of said sleeve to limit inward movement thereof with respect to said mounting wall, said head having outwardly extending parallel wall portions defining a space therebetween conveniently accessible only to narrow tools such as the jaws of thin-nose pliers, said sleeve having resilient wall portions capable of flexing inwardly, and latching devices on the exterior surfaces of said resilient wall portions adapted to pass through said aperture by inward flexing of said wall portions in combination with a plug adapted to be received in the receptacle and to fit within said sleeve so closely as to prevent inward flexing of said wall portions to an extent which would release said latching devices from engagement with said mounting wall adjacent said aperture, said plug having an outermost head portion normally disposed between said wall portions when said plug is fully received by said receptacle, said outermost head portion of the plug being bifurcated, and said parallel wall portions and said outermost head portion having coacting latch means which latch means is releasable by moving the bifurcated parts of said plug toward each other.
