Abstract

A method for terminating cable having a plurality of individually insulated conductors covered by a sheath, first by slitting or removing slices of the sheath to expose lengths of said conductors, then spreading apart the conductors laterally from each other, precisely locating the spread apart conductors in a desired lateral adjacent spaced relationship, then electrically connection an electrical terminal to each of the conductors. Such terminals are either sequentially or simultaneously connected to the conductors. The terminals may be of the insulation piercing type. Alternatively, the individual conductors may be stripped and terminated with terminals which need not be of the insulation piercing type.

Claims

1. In a method for preparing a sheath covered three conductor cable, including two outer conductors individually covered with insulation and a centrally located uninsulated ground conductor, for assembly with electrical terminals contained in a housing, the improvement comprising the steps of:

piercing said sheath on opposite sides of said ground conductor,

slicing entirely through said cable intermediate the ends thereof and longitudinally on both sides of said ground conductor and between said ground conductor and each of said insulation covered conductors to divide said sheath into longitudinal slitted portions overlying said conductors,

spreading apart said insulation covered conductors laterally from said ground conductor while maintaining said slitted portions of said sheath over said insulation covered conductors,

locating said ground conductor and said spread apart insulation covered conductors together with said slitted portions of said sheath over corresponding electrical terminals in said housing, with said conductors and with said outer sheath extending uninterrupted from one open end of said housing to another open end thereof,

forcibly inserting said spread apart conductors together with said slitted portions of said sheath in between two slicing edges of corresponding spaced apart electrical terminals, thereby forcing the slicing edges to slice through the slitted portions of said sheath and the insulation covering said outer conductors, resulting in a high speed termination of said three conductor cable without interrupting either the conductors or the outer sheath.

2. In the method for terminating a sheath covered conductor cable, having two outer conductors individually covered with insulation and a centrally located uninsulated ground conductor, with said conductors being forcibly inserted between slicing edges of corresponding electrical contacts contained in a prong receiving electrical outlet housing, the improvement comprising the steps of:

slicing entirely through said cable intermediate the ends thereof in two locations longitudinally on both sides of said ground conductor and between said ground conductor and each of said outer conductors,

said sheath and filler material packed inside said sheath and in between said ground conductor and said outer conductors both being divided into longitudinal slitted portions intermediate the ends of said cable,

spreading apart portions of said insulation covered outer conductors together with corresponding slitted portions of said sheath and said filler material laterally away from said ground conductor and corresponding slitted portions of said sheath which are on opposite sides of said ground conductor,

locating said spread apart conductors and said slitted portions of said sheath and said filler material in said housing with said cable sheath, filler material and conductors extending uninterrupted from one open end of said housing to another open end thereof,

forcibly inserting said spread apart conductors and said ground conductor simultaneously in between said slicing edges of corresponding electrical contacts, forcing said terminals to slice through or push away said sheath and said filler material for penetration through the insulation covering said outer conductors and for gripped electrical engagement with said outer conductors and said ground conductor, thereby terminating said three conductor cable with an outlet receptacle housing at high speed without severing or removing any portions of said cable.

3. The method as recited in claim 2 and further including the steps of:

impinging a cover against said slitted portions of said cable and displacing said cover toward said housing to forcibly insert said conductors in between said slicing edges of said contacts, and

latchably securing said cover on said housing and retaining said cover engaged against said slitted portions of said cable to retain said conductors in between the slicing edges of said contacts.

4. The method as recited in claim 2, and further including the steps of:

providing a separate housing containing a plurality of electrical terminals at each of selected intervals along said cable sheath, and electrically and mechanically connecting said spread apart portions of said insulation covered conductors to corresponding electrical terminals contained within corresponding housings, and electrically connecting said ground conductor to corresponding electrical terminals contained in corresponding housings, whereby said housings are located at intervals along said cable sheath with the electrical terminals of said housings electrically connected to said insulation covered conductors and said centrally disposed ground conductor at said intervals along said cable sheath.
