Abstract
Abstract Disclosed are heat recoverable connectors for use as a protective covering about a plurality of joined articles such as wire splices or tubing junctures. The connectors are open-ended and feature at least one internal wall extending for at least a portion of the distance along the length of the connector to provide a plurality of open-ended channels within the connector for respectively containing one or more of the plurality of joined articles so as to insure their separation during the process of shrinking the connector by heat.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
217 words
An elongate open-ended connector made from a heat recoverable material having an elastic memory and able to be shrunken by heat from an expanded state to a contracted state to provide an individual protective covering about a plurality of joined articles, said connector in the expanded state comprising, an outer surrounding wall extending along the length of the connector between one end thereof and an opposite end thereof and at least one internal wall extending for at least a portion of the distance along the length of the connector within said outer wall and integrally related therewith that partitions the connector within the outer wall into a plurality of open-ended channels extending between said ends of the connector, said channels having a cross-sectional shape adapted to receive and permit the positioning of the joined articles therewithin, said internal wall having a length thereof sufficient to encapsulate the area of juncture between the respective articles positioned within each of the channels, and said internal wall and said outer wall adapted to contract snugly about the joined articles and thicken without melting to control drift of the joined article towards each other and provide an individual and combined protective covering thereabout of reduced bulk that assures adequate spacing between the joined articles when the connector is contracted by heat.

Claim 3
Dependent Claim
57 words
The connector of claim 1 including an open-ended cavity disposed at each of said ends within said outer wall that communicate with said channels and are adapted to respectively receive the end of an object from which the plurality of articles extend and to which the connector contracts snugly about when the connector is contracted by heat.
Claim 4
Dependent Claim
55 words
The connector of claims 1 or 2 including a layer of adhesive disposed on the inner surface of the outer wall and on the surfaces of the inner walls enclosing the channels, said adhesive adapted to enhance the sealed engagement between the connector and the articles without degradation when the connector is contracted by heat.
Claim 5
Dependent Claim
57 words
The connector of claims 1 or 2 including a layer of fusible material disposed on the inner surface of the outer wall and on the surfaces of the inner walls enclosing the channels, said fusible material adapted to enhance the sealed engagement between the connector and the articles without degradation when the connector is contracted by heat.
Claim 6
Dependent Claim
45 words
The connector of claim 2 including a layer of adhesive disposed on the inner surface of the outer wall enclosing said cavities, said adhesive adapted to enhance the sealed engagement between the connector and said objects without degradation when the connector is contracted by heat.
Claim 7
Dependent Claim
45 words
The connector of claim 2 including a fusible material disposed on the inner surface of the outer wall enclosing said cavities, said fusible material adapted to enhance the sealed engagement between the connector and said objects without degradation when the connector is contracted by heat.
