Abstract
Abstract The invention provides an improved method for forming a cover layer over a joint of electrical wires. Portions of insulation layers of wires to be joined are stripped and the bared conductors of the wires assembled in a desired configuration to form a joint. The joint is placed in a transparent mold and the mold is filled with a photosetting resin. Radiation of an appropriate wavelength is then passed through the mold to harden the resin.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
59 words
A method for forming a cover layer over a joint of electrical wires, comprising the steps of: assembling a plurality of electrical wires to form a joint; placing said joint in a transparent mold; filling said mold with a photosetting resin; applying radiation through said mold to harden said resin; and removing said mold after said resin is hardened.
Claim 2
Independent Claim
59 words
A method for forming a cover layer over a joint of electrical wires, comprising the steps of: assembling a plurality of electrical wires to form a joint; placing said joint in a transparent mold; filling said mold with a photosetting resin; applying radiation through said mold to harden said resin; and removing said mold after said resin is hardened.
Claim 3
Dependent Claim
39 words
The method for forming a cover layer of claim 1, wherin said mold has top and bottom parts, and said step of filling said mold comprises injecting liquid resin material through a resin injecting port in said top part.
Claim 4
Dependent Claim
28 words
The method for forming a cover layer of claim 1, wherein said photsetting resin is of a type which adheres to insulation layers of said wires when hardened.
Claim 5
Dependent Claim
59 words
The method for forming a cover layer of claim 1, further comprising an initial step of stripping portions of insulation layers from said wires, and wherein, in said step of placing said joint in said mold, remaining portions of said insulation layers are positioned at edge portions of said mold so that said resin adhere to said remaining portions.
Claim 6
Independent Claim
59 words
A method for forming a cover layer over a joint of electrical wires, comprising the steps of: assembling a plurality of electrical wires to form a joint; wrapping said joint with an insulating electrical tape; placing said joint in a transparent mold; filling said mold with a photosetting resin; and applying radiation through said mold to harden said resin.
Claim 7
Independent Claim
59 words
A method for forming a cover layer over a joint of electrical wires, comprising the steps of: assembling a plurality of electrical wires to form a joint; wrapping said joint with an insulating electrical tape; placing said joint in a transparent mold; filling said mold with a photosetting resin; and applying radiation through said mold to harden said resin.
Claim 8
Dependent Claim
30 words
The method for forming a cover layer of claim 5, wherein said mold is formed from a thin transparent sheet and is left as a part of said cover layer.
