Abstract
Abstract Method and apparatus is provided in which a heat shrinkable member is recovered over an annular disk or the like. The disk includes an aperture therethrough which, along with the unrecovered portion of the heat shrinkable member, provides a pathway for a cable or the like. The unrecovered portion of the heat shrinkable member is recovered onto the cable as a strain relief device.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
129 words
A strain relief kit comprising: a plug member having a rear wall with a first aperture formed therein; a heat shrinkable sleeve having a first and second portion, said first portion being in a recovered state and said second portion being in an expanded state and forming a pathway capable of receiving an electrical cable, said second portion of said heat shrinkable sleeve capable of being positioned in said first aperture of said plug, and a disk having a diameter larger than said first aperture and having annular faces defining one centrally located second aperture, said first portion of said sleeve being recovered onto said faces, said second aperture being in alignment with said pathway thereby forming a further part of the pathway capable of receiving an electrical cable.
Claim 2
Dependent Claim
129 words
A strain relief kit comprising: a plug member having a rear wall with a first aperture formed therein; a heat shrinkable sleeve having a first and second portion, said first portion being in a recovered state and said second portion being in an expanded state and forming a pathway capable of receiving an electrical cable, said second portion of said heat shrinkable sleeve capable of being positioned in said first aperture of said plug, and a disk having a diameter larger than said first aperture and having annular faces defining one centrally located second aperture, said first portion of said sleeve being recovered onto said faces, said second aperture being in alignment with said pathway thereby forming a further part of the pathway capable of receiving an electrical cable.
Claim 3
Dependent Claim
11 words
The kit of claim 1 wherein said disk is a metal.
Claim 4
Dependent Claim
18 words
