Abstract
Abstract A process for environmentally sealing and strain relieving at least one electrical lead wire connected to an interior terminal of a connector of the type which possesses a tubular orifice through which the lead wire extends comprising the steps of disposing a laminated disc comprising a lower layer of foaming adhesive, an upper layer of fusible adhesive, and an aperture corresponding to each electrical lead wire within the tubular orifice with the lead wires extending through the corresponding apertures; and heating the disc whereby the foaming adhesive is caused to foam and the fusible adhesive is caused to melt and flow.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
A process for environmentally sealing at least one electrical lead wire connected to an interior terminal of a connector of the type which possesses a tubular member through which said lead wire extends comprising the steps of: (a) disposing a laminated disc comprising a lower layer of foamable adhesive, an upper layer of fusible adhesive, and an aperture corresponding to each said at least one electrical lead wire within said tubular member, with said lead wire extending through said corresponding aperture; and (b) heating said disc whereby said foaming adhesive is caused to foam and said fusible adhesive is caused to melt and flow, and to seal between said lead wire and an interior surface of said member.
Claim 2
Dependent Claim
118 words
A process for environmentally sealing at least one electrical lead wire connected to an interior terminal of a connector of the type which possesses a tubular member through which said lead wire extends comprising the steps of: (a) disposing a laminated disc comprising a lower layer of foamable adhesive, an upper layer of fusible adhesive, and an aperture corresponding to each said at least one electrical lead wire within said tubular member, with said lead wire extending through said corresponding aperture; and (b) heating said disc whereby said foaming adhesive is caused to foam and said fusible adhesive is caused to melt and flow, and to seal between said lead wire and an interior surface of said member.
Claim 3
Dependent Claim
24 words
A process in accordance with claim 1 wherein the foaming temperature of said foamable adhesive is below the melting point of said fusible adhesive.
Claim 4
Dependent Claim
34 words
A process in accordance with claim 1 wherein said foamable adhesive layer is capable of being heated by a high frequency field and foaming of the foamable adhesive layer is effected by dielectric heating.
