Abstract
Abstract A device for electrically connecting together two wires and sealing the joint comprises a dimensionally-recoverable sleeve (2) having a central solder insert (3) and end adhesive inserts (4,5). The adhesive inserts comprise a higher viscosity adhesive (5) that acts as a dam restricting flow of the lower viscosity adhesive (4).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
92 words
A device for forming a solder connection between a plurality of elongate bodies, which comprises: a hollow, dimensionally heat-recoverable article having an aperture therein, the article containing a solder insert for forming a solder connection between the bodies, and first and second heat-activatable adhesive inserts for environmentally sealing said aperture, said second adhesive insert having a higher viscosity than said first insert at the recovery temperature of the article, and being positioned with respect to the first insert to restrict flow of the first insert under the recovery force of the sleeve.
Claim 2
Independent Claim
92 words
A device for forming a solder connection between a plurality of elongate bodies, which comprises: a hollow, dimensionally heat-recoverable article having an aperture therein, the article containing a solder insert for forming a solder connection between the bodies, and first and second heat-activatable adhesive inserts for environmentally sealing said aperture, said second adhesive insert having a higher viscosity than said first insert at the recovery temperature of the article, and being positioned with respect to the first insert to restrict flow of the first insert under the recovery force of the sleeve.
Claim 3
Dependent Claim
18 words
A device according to claim 1, in which the first and second inserts each comprise a hot-melt adhesive.
Claim 4
Dependent Claim
40 words
A device according to claim 1 or claim 2, in which two said second adhesive inserts are provided positioned with respect to the first insert to restrict flow of the insert respectively towards said aperture and away from said aperture.
Claim 5
Independent Claim
25 words
A device according to any one of claims 1 to 3, in which the first and second inserts comprise parts of an integral adhesive member.
Claim 6
Independent Claim
36 words
A device according to any one of claims 1 to 4, in which the first and second inserts each comprise a blend of polymers, the two blends comprising substantially the same polymers but in different proportions.
Claim 7
Independent Claim
39 words
A device according to any one of claims 1 to 5, in which the first and second inserts comprise substantially the same polymer or polymers, the second insert having been cross-linked to a greater extent than the first insert.
Claim 8
Independent Claim
30 words
A device according to any of claims 1 to 6, in which the second insert has a viscosity greater than that of the first insert throughout the temperature range 90-200°C.
Claim 9
Independent Claim
30 words
A device according to any of claims 1 to 7, in which the article comprises a substantially cylindrical sleeve having a length of 0.5-5 cm and a diameter 0.2-3 cm.
