Abstract
Abstract A method of manufacturing connector of the composite sleeve type having an inner sleeve carrying a plurality of tangs for piercing insulation and engaging the metal wires of a plurality of electrical conductors inserted into the inner bore in the sleeve to interconnect the conductors responsive to a crimping of the connector, wherein the connector includes a liner of thin, filmlike material disposed within the bore in the inner sleeve opposite the distal ends of the tangs and the liner is retained in assembly with the connector by a reversely bent extension thereof which is sandwiched between the outer surface of the outermost metallic sleeve of the connector and the inner surface of the outer insulative jacket of the composite sleeve forming the connector.

Claim 1
Independent Claim
305 words
A method of manufacturing an electrical connector of the composite sleeve type having an outer jacket of insulating material, a pair of telescopically disposed metallic sleeves positioned within said jacket, and a liner having a portion thereof disposed within the inner of said metallic sleeves and an extension of said portion disposed between the outer of said metallic sleeves and the jacket comprising: (1) providing a die having a vertically extending elongated post, said post having a width less than the width of the central bore in said inner metallic sleeve; (2) providing an open ended tube of electrical insulating material of predetermined length and placing said tube on said die such that said elongated post is disposed within said tube substantially coaxially therewith; (3) placing a strip of electrically nonconductive, thin, filmlike material over the upper end of said tube such that the longer axis of said strip lies substantially transverse the longitudinal axis of the tube; (4) inserting said telescopically disposed metallic sleeves, open end leading, into said tube, whereby said strip is carried down into said tube and engaged by the upper end of said post and a portion of said strip is carried by said post into said central bore in said inner metallic sleeve substantially to the full depth of said bore to form said liner and other portions of said strip are reversely bent around the leading end wall of said outer sleeve and directed toward the remote end of said sleeve between the outer wall thereof and the inner wall of said tube to form said extension of said liner; (5) shrinking said tUbe on said outer sleeve to form said jacket and sandwich said last above mentioned portions of said strip between said jacket and said outer metallic sleeve; and (6) removing said connector from said die.
Claim 2
Independent Claim
305 words
A method of manufacturing an electrical connector of the composite sleeve type having an outer jacket of insulating material, a pair of telescopically disposed metallic sleeves positioned within said jacket, and a liner having a portion thereof disposed within the inner of said metallic sleeves and an extension of said portion disposed between the outer of said metallic sleeves and the jacket comprising: (1) providing a die having a vertically extending elongated post, said post having a width less than the width of the central bore in said inner metallic sleeve; (2) providing an open ended tube of electrical insulating material of predetermined length and placing said tube on said die such that said elongated post is disposed within said tube substantially coaxially therewith; (3) placing a strip of electrically nonconductive, thin, filmlike material over the upper end of said tube such that the longer axis of said strip lies substantially transverse the longitudinal axis of the tube; (4) inserting said telescopically disposed metallic sleeves, open end leading, into said tube, whereby said strip is carried down into said tube and engaged by the upper end of said post and a portion of said strip is carried by said post into said central bore in said inner metallic sleeve substantially to the full depth of said bore to form said liner and other portions of said strip are reversely bent around the leading end wall of said outer sleeve and directed toward the remote end of said sleeve between the outer wall thereof and the inner wall of said tube to form said extension of said liner; (5) shrinking said tUbe on said outer sleeve to form said jacket and sandwich said last above mentioned portions of said strip between said jacket and said outer metallic sleeve; and (6) removing said connector from said die.
Claim 3
Dependent Claim
50 words
A method according to claim 1 wherein said strip of thin, filmlike material is drawn from a continuous roll of said material and severed to provide the requisite length of said material to form said liner and said extension of said liner during insertion of said sleeves into said tube.
Claim 4
Dependent Claim
64 words
A method according to claim 2 wherein said strip of thin, filmlike material is carried a substantial distance down into said tube and over said post while remaining connected to said continuous roll of said material and is severed from said roll to provide said requisite strip length during the final descent portion of said sleeves'' travel toward the lower portion of said die.
