US Patent:

RE308170, Dec 8, 1981

Filed:

Feb 22, 1979

Appl. No.:

6/014120

Inventors:

Patrick V. Loyd - West Laurel MD
Samuel M. Mills - University Park MD

Assignee:

J. L. Clark Manufacturing Co. - Rockford IL

International Classification:

B29C 2700
B32B 3100

US Classification:

156 86

Abstract:

A laminated tubular connector for splicing or terminating electric conductors, comprising an outer layer of a heat shrinkable dielectric material, e. g. , polyethylene terephthalate, and an inner layer of a relatively soft, self-adhesive, low temperature flowable thermoplastic material, preferably a polyvinyl acetate composition. When heat is applied to the connector, the outer layer shrinks and the inner layer functions as a sealant and a cushioning agent. The adhesiveness of the inner layer may be used to hold the connector in place during subsequent operations by pinching the connector so that the depressed portions of the tube adhere to each other prior to heating the connector to shrink the outer layer.

Abstract:

A laminated tubular connector for splicing or terminating electric conductors, comprising an outer layer of a heat shrinkable dielectric material, e. g. , polyethylene terephthalate, and an inner layer of relatively soft, self-adhesive, low temperature flowable thermoplastic material, preferably a polyvinyl acetate composition. When heat is applied to the connector, the outer layer shrinks and the inner layer functions as a sealant and a cushioning agent. In some applications, the adhesiveness of the inner layer may be used to hold the connector in place during subsequent operations by pinching the connector so that the depressed portions of the tube adhere to each other prior to heating the connector to shrink the outer layer.
