Abstract
Abstract A wire connector comprising an outer socket and an inner socket, both of which being tubular shaped and formed of insulating material and adapted to be inserted one into the other. The inner socket has a split extending longitudinally along its full length. A double ended needle is prelaid in the center of the inner socket by being retained in a partition wall therein. The wire ends to be connected are inserted into opening of the inner socket, so that the needle ends penetrate into the cores of the wire ends. The outer socket serves to tighten the inner socket to obtain a positive gripping of the wire ends. A U-shaped spike is provided through the side wall of the inner socket, with two points thereof penetrating the coating of the wires to enhance the connecting effect.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
261 words
A connector for connecting electrically conductive wires together comprising: an inner socket of tubular construction, said inner socket comprising: a longitudinal opening, a partition wall disposed within said opening dividing said opening into two sections adapted to receive the ends of electrically conductive wires to be connected; enlarged portions at opposite ends of the inner socket establishing therebetween a portion of reduced cross-section; a split extending completely through the outer periphery of said inner socket and said enlarged portions; a shallow groove formed in the outer periphery of said portion of reduced cross-section, said groove extending parallel to the axis of said opening and having holes at the ends thereof communicating with said two sections of said opening; an outer socket of tubular construction configured to fit around said portion of reduced cross section; an electrically conductive needle fixedly secured within said partition wall so as to extend axially within said inner sleeve, said needle having points at both ends projecting beyond the partition wall and into the opening sections so as to penetrate the ends of the electrically conductive wires being connected; and a spike insertable in said portion of reduced cross section, said spike including a bight portion sized for reception in said groove, and pointed arm portions positioned to extend through said holes and penetrate the ends of the electrically conductive wires being connected; said outer socket being insertable around said portion of reduced cross section to cover said spike and tighten said portion of reduced cross section against the ends of the electrically conductive wires being connected.
Claim 2
Dependent Claim
261 words
A connector for connecting electrically conductive wires together comprising: an inner socket of tubular construction, said inner socket comprising: a longitudinal opening, a partition wall disposed within said opening dividing said opening into two sections adapted to receive the ends of electrically conductive wires to be connected; enlarged portions at opposite ends of the inner socket establishing therebetween a portion of reduced cross-section; a split extending completely through the outer periphery of said inner socket and said enlarged portions; a shallow groove formed in the outer periphery of said portion of reduced cross-section, said groove extending parallel to the axis of said opening and having holes at the ends thereof communicating with said two sections of said opening; an outer socket of tubular construction configured to fit around said portion of reduced cross section; an electrically conductive needle fixedly secured within said partition wall so as to extend axially within said inner sleeve, said needle having points at both ends projecting beyond the partition wall and into the opening sections so as to penetrate the ends of the electrically conductive wires being connected; and a spike insertable in said portion of reduced cross section, said spike including a bight portion sized for reception in said groove, and pointed arm portions positioned to extend through said holes and penetrate the ends of the electrically conductive wires being connected; said outer socket being insertable around said portion of reduced cross section to cover said spike and tighten said portion of reduced cross section against the ends of the electrically conductive wires being connected.
Claim 3
Dependent Claim
36 words
A connector according to claim 1 wherein said split extends radially to the center of said partition, said needle being sized to be inserted through said split and retained at the center of said partition wall.
Claim 4
Dependent Claim
20 words
A connector according to claim 1 wherein the length of said needle generally equals the length of said inner socket.
Claim 5
Dependent Claim
29 words
A connector according to claim 1 wherein the inner diameter of the outer socket is smaller than the outer diameter of the enlarged end portions of the inner socket.
