Abstract
Abstract The device for enclosing at least part of an elongation object, preferably a connection between electrical conductors, comprising a hollow dimensionally recoverable article having an aperture that communicates between the interior and the exterior of the article, and a quantity of material which seals an aperture. The material is self sealing so that it will allow penetration of a test probe through the material and will continue to seal the article after removal of the probe. Advantageously the article contains an arrangement for connecting electrical conductors, for example a solder insert or crimping connector.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
150 words
A device for forming and enclosing an electrical connection between a plurality of electrical conductors, which comprises: (a) a hollow, dimensionally-recoverable article having a first and a second dimensionally-recoverable end portion and a central portion, the first end portion being open to allow insertion of electrical conductors therein and the second end portion having an aperture that communicates between the interior and the exterior of the article; (b) an arrangement for electrically connecting electrical conductors, which is located in the central portion of the article; and (c) a quantity of self-supporting material which is located in the second end portion and held therein by the article, wherein, at least after the article has been recovered, the material seals the aperture but can be penetrated by a probe, the material being self-sealing at least when held by the article so that it will seal the aperture after removal of a probe.
Claim 2
Independent Claim
150 words
A device for forming and enclosing an electrical connection between a plurality of electrical conductors, which comprises: (a) a hollow, dimensionally-recoverable article having a first and a second dimensionally-recoverable end portion and a central portion, the first end portion being open to allow insertion of electrical conductors therein and the second end portion having an aperture that communicates between the interior and the exterior of the article; (b) an arrangement for electrically connecting electrical conductors, which is located in the central portion of the article; and (c) a quantity of self-supporting material which is located in the second end portion and held therein by the article, wherein, at least after the article has been recovered, the material seals the aperture but can be penetrated by a probe, the material being self-sealing at least when held by the article so that it will seal the aperture after removal of a probe.
Claim 3
Dependent Claim
13 words
A device according to claim 1, in which the material is inherently self-sealing.
Claim 4
Dependent Claim
23 words
A device according to claim 1, which comprises a first heat-recoverable portion, and a second non recoverable portion that contains said self-sealing material.
Claim 5
Dependent Claim
18 words
A device according to claim 1, in which the article is in the form of a tubular sleeve.
Claim 6
Dependent Claim
41 words
A device according to claim 1, in which the article is in the form of a tubular sleeve, one end of which is closed by the said material, and the other end of which is open and has a heat-activatable adhesive.
Claim 7
Dependent Claim
9 words
A device according to claim 1, which is heat-recoverable.
Claim 8
Dependent Claim
33 words
A device according to claim 1, in which the self-sealing material is positioned such that, on partial recovery of the article, the forces of recovery cause the material to be held in place.
Claim 9
Dependent Claim
16 words
A device according to claim 1, in which the self sealing material is an elastomeric material.
Claim 10
Independent Claim
144 words
A device for forming and enclosing an electrical connection between a plurality of electrical conductors, which comprises: (a) a hollow, dimensionally-recoverable article having a first and a second dimensionally-recoverable end portion and a central portion, the first end portion being open to allow insertion of electrical conductors therein and the second end portion being closed; (b) an arrangement for electrically connecting electrical conductors, which is located in the central portion of the article; and (c) a quantity of material which is located in the second end portion and held therein by the article, and which can be penetrated by a probe inserted into the second end portion of the article from the exterior thereof, the material being self-sealing at least when held by the article so that, after removal of a probe, it will seal any aperture formed in the article by a probe.
Claim 11
Independent Claim
144 words
A device for forming and enclosing an electrical connection between a plurality of electrical conductors, which comprises: (a) a hollow, dimensionally-recoverable article having a first and a second dimensionally-recoverable end portion and a central portion, the first end portion being open to allow insertion of electrical conductors therein and the second end portion being closed; (b) an arrangement for electrically connecting electrical conductors, which is located in the central portion of the article; and (c) a quantity of material which is located in the second end portion and held therein by the article, and which can be penetrated by a probe inserted into the second end portion of the article from the exterior thereof, the material being self-sealing at least when held by the article so that, after removal of a probe, it will seal any aperture formed in the article by a probe.
Claim 12
Dependent Claim
