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

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
116 words
A device for forming a solder connection between a plurality of elongate bodies, which comprises: a hollow, dimensionally heat-recoverable sleeve 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, the first and second adhesive inserts each comprising a blend of polymers, the two blends comprising substantially the same polymers but in different proportions, said second adhesive insert having a higher viscosity that said first insert at the recovery temperature of the sleeve, 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
116 words
A device for forming a solder connection between a plurality of elongate bodies, which comprises: a hollow, dimensionally heat-recoverable sleeve 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, the first and second adhesive inserts each comprising a blend of polymers, the two blends comprising substantially the same polymers but in different proportions, said second adhesive insert having a higher viscosity that said first insert at the recovery temperature of the sleeve, 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
37 words
A device according to claim 1, 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
Dependent Claim
20 words
A device according to claim 1, in which the first and second inserts comprise parts of an integral adhesive member.
Claim 6
Dependent Claim
34 words
A device according to claim 1, 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 7
Dependent Claim
27 words
A device according to claim 1, in which the second insert has a viscosity greater than that of the first insert throughout the temperature range 90°-200° C.
Claim 8
Dependent Claim
24 words
A device according to claim 1, in which the sleeve is substantially cylindrical having a length of 0.5-5 cm and a diameter 0.2-3 cm.
Claim 9
Independent Claim
117 words
A device for forming a solder connection between a plurality of elongate bodies, which comprises: a hollow, dimensionally heat-recoverable sleeve 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, the first and second adhesive inserts comprising substantially the same polymer or polymers, the second insert having been crosslinked to a greater extent than the first insert so that it has higher viscosity than said first insert at the recovery temperature of the sleeve, and being positioned with respect to the first insert to restrict flow of the first insert under the recovery force of the sleeve.
Claim 10
Independent Claim
117 words
A device for forming a solder connection between a plurality of elongate bodies, which comprises: a hollow, dimensionally heat-recoverable sleeve 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, the first and second adhesive inserts comprising substantially the same polymer or polymers, the second insert having been crosslinked to a greater extent than the first insert so that it has higher viscosity than said first insert at the recovery temperature of the sleeve, and being positioned with respect to the first insert to restrict flow of the first insert under the recovery force of the sleeve.
Claim 11
Dependent Claim
18 words
A device according to claim 8, in which the first and second inserts each comprise a hot-melt adhesive.
Claim 12
Dependent Claim
37 words
A device according to claim 8, 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 13
Dependent Claim
20 words
A device according to claim 8, in which the first and second inserts comprise parts of an integral adhesive member.
Claim 14
Dependent Claim
31 words
A device according to claim 8, 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 15
Dependent Claim
27 words
A device according to claim 8, in which the second insert has a viscosity greater than that of the first insert throughout the temperature range 90°-200° C.
Claim 16
Dependent Claim
24 words
A device according to claim 8, in which the sleeve is substantially cylindrical having a length of 0.5-5 cm and a diameter 0.2-3 cm.
