Abstract
Abstract The plastic insulated cross-connection wires on the backside of an electrical panel are coaxed by momentarily applying a mass of molten, low melting temperature metal to the backside of the panel with the major portion then removed. The adhering portion solidifies and the shielded cross-connections are potted in a plastic mass to maintain the wires in position and to protect the same against mechanical impact.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
32 words
The method as claimed in claim 1 wherein the temperature gap between the temperature of the applied molten metal and the melting temperature of the synthetic resinous wire insulation is approximately 20*.
Claim 2
Dependent Claim
40 words
The method as claimed in claim 1 wherein said low temperature melting point metal comprises alloys of bismuth with one metal of the group consisting of tin, lead, cadmium or indium, and said wires are coated by polytetraflorethylene insulation material.
Claim 3
Dependent Claim
44 words
The method as claimed in claim 1 further including the step of potting the metal coated wires with a mass of plastic material to embed the metal coated wires in a solid plastic mass to increase panel rigidity while physically protecting the interconnecting wires.
Claim 4
Dependent Claim
61 words
The method as claimed in claim 1 wherein the step of momentarily applying a mass of molten metal to the side of the panel carrying said insulated wires comprises momentary dipping of said wired back panel into a bath of molten metal and immediately removing the same whereby a thin layer of molten material adheres to the insulation covering said wires.
Claim 5
Dependent Claim
85 words
The method as claimed in claim 1 for a back panel including a frame member extending about the periphery of said panel backside and acting in conjunction therewith to form a well area, said method further including the steps of; positioning said panel with the well side up, filling said well area with liquid plastic material and cooling said assembly to embed the coated insulated wire portions in a solid plastic mass to produce a high strength, light weight panel having metal shielded wire interconnections.
Claim 6
Dependent Claim
57 words
The method as claimed in claim 1 wherein said low melting temperature molten metal mass comprises one material of the group consisting of; alloys of bismuth with tin, lead, cadmium or indium, and antimony, and said wire is coated with one insulation material of the group consisting of polytetraflorethylene, butyl rubber, enamel, polyethylene, nylon and silicon rubber.
Claim 7
Dependent Claim
16 words
The method of claim 1 wherein said wire is mounted in sealing conformation through said panel.
