Abstract
Abstract A cable connector assembly to connect an electrical cable to a plug or a light socket and positively securely retain the cable in assembly with the plug or socket. The assembly is comprised of a main body portion defining the plug or socket provided with prongs extending therefrom for electrical connection with an outlet or the like, and which is constructed in the form of a cup member to receive a cable and wire retaining member which is provided with conductor means in contact with the wires of the cable which are adapted to be engaged by the inner ends of the prongs of the plug or socket. The cable-retaining member is constructed and has provisions to cooperate with a cable-clamping member adapted to be inserted over a portion of the cableretaining member and which is provided with resilient cableclamping means in the form of resilient fingers extending through slots provided in the cable-retaining member, and a pressure ring is provided having internal cam surfaces located on varying radii adapted to be pushed over the clamping and cable-retaining member to cam the resilient fingers inwardly through the slots in the cable-retaining member into engagement with the cable to lock the cable to the cable-retaining member; the assembly of the electrical connector is completed by a sealing ring and an end cap adapted to be screwed into the main body portion of the plug or light socket to thereby confine the cable retaining and clamping members in between them. All of the parts, except for the prongs on the plug or light socket and the wire-connecting means in the cable-retaining member, are made of a nonconductive material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
203 words
In an electrical cable connector assembly having a main body portion defining a cup-shaped member having a closed end and an open end, the improvement comprising in combination: a. a first member having a portion adapted to receive one end of said cable and having individual means to each receive a wire of said cable; said first member being adapted to be inserted into said main body portion through said open end thereof; b. a second member comprising a cable clamp disposed over said cable adjacent said first member having a resilient cable clamping means disposed for extension through said cable receiving portion of said first member towards said cable; c. a third member comprising a pressure ring adapted for coacting pushover engagement over said second member and said cable-receiving portion of said first member to thereby depress said resilient cable clamping means into clamping engagement with said cable; and d. a fourth member defining an end clamp disposed over said cable having means for attachment to said main body portion over said first, second and third member to thereby close said open end of said main body portion and securely confine said members within said main body portion and said end cap.
Claim 2
Dependent Claim
203 words
In an electrical cable connector assembly having a main body portion defining a cup-shaped member having a closed end and an open end, the improvement comprising in combination: a. a first member having a portion adapted to receive one end of said cable and having individual means to each receive a wire of said cable; said first member being adapted to be inserted into said main body portion through said open end thereof; b. a second member comprising a cable clamp disposed over said cable adjacent said first member having a resilient cable clamping means disposed for extension through said cable receiving portion of said first member towards said cable; c. a third member comprising a pressure ring adapted for coacting pushover engagement over said second member and said cable-receiving portion of said first member to thereby depress said resilient cable clamping means into clamping engagement with said cable; and d. a fourth member defining an end clamp disposed over said cable having means for attachment to said main body portion over said first, second and third member to thereby close said open end of said main body portion and securely confine said members within said main body portion and said end cap.
Claim 3
Dependent Claim
149 words
In the assembly as defined in claim 1, said first member being constructed of a cable receiving hub portion and an enlarged radial flange portion integral therewith having an axial bore extending through both said hub portion and said flange portion for extension of said cable therethrough; said hub portion being provided with radially spaced longitudinal slots and having a reduced diameter end section adjacent said slots; said second member comprising a cylindrical body portion for seating engagement on said reduced diameter end section of said hub portion and having resilient cable clamping means comprising resilient fingers extending axially from said body portion in radially spaced relationship corresponding to said radial spacing between said slots in said hub portion of said first member for extension of said resilient fingers into said slots, the free ends of said fingers extending normally upwardly from the radial surface of said hub portion.
Claim 4
Dependent Claim
116 words
In the assembly as defined in claim 2, each of said resilient fingers being provided with gripping means at the underside of said fingers extending into said slots; said third member comprising said pressure ring having a contoured inner surface defining spaced cam sections adapted to slidingly engage the upwardly extending free ends of said fingers when pushed over said body portion of said second member and said hub potion of said first member in associated coacting relationship therewith to thereby depress said fingers inwardly of said slots to provide maximum locking engagement of said clamping means with said cable when said pressure ring is moved into abutment against said flange portion of said first member.
Claim 5
Dependent Claim
64 words
In the assembly as defined in claim 3, said third member comprising said pressure ring having a circumferential flange adapted to be clamped in assembly between said flange portion of said first member and the inner end of said end cap when said end cap is attached to said main body portion to thereby retain said pressure ring in position over said resilient fingers.
Claim 6
Dependent Claim
43 words
In the assembly as defined in claim 2, said individual wire receiving means of said first member being disposed in said flange portion and comprising radially spaced apertures provided therein for extension of a wire from said cable into each of said apertures.
Claim 7
Dependent Claim
140 words
In the assembly as defined in claim 5, said main body portion and said first, second, third and fourth members all being made of a nonconducting material; said wire receiving apertures and said flange portion each retaining a metal conductor for electrical contact with said wires; said main body portion having a plurality of electrically conducting prongs each having a first portion extending from the closed end thereof outwardly, and a second portion extending inwardly of said main body portion; said second inwardly extending portions of said prongs being radially spaced in correspondence with the radial spacing of said apertures in said flange portion of said first member for extension into said apertures when said first member is inserted within said main body portion to thereby establish electrical contact with said wires and said metal conductors retained in said apertures.
Claim 8
Dependent Claim
54 words
In the assembly as defined in claim 1, the further provision of an insulated sealing member disposed around said cable between said third member and said end cap to be clamped therebetween when said end cap is attached to said main body portion to thereby prevent entrance of moisture into said main body portion.
Claim 9
Dependent Claim
62 words
In the assembly as defined in claim 1, the open end of said main body portion being provided with internal threads and said end cap being provided with external threads to permit said end cap to be screwed into said main body portion for confinement of said first, second and third member in between said main body portion and said end cap.
Claim 10
Dependent Claim
43 words
In the assembly as defined in claim 3, said contoured inner surface of said pressure ring comprising a plurality of equally radially spaced cam surfaces each disposed on radii of varying dimensions to thereby permit selective clamping engagement with cables of different diameters.
