Abstract
Abstract An electrical crimp connector includes a plurality of dimples disposed between an outer surface of a crimping body and an inner surface of a polymeric envelope, with an insulating gel being disposed in a space between the crimping body and the envelope formed by the dimples. Upon crimping the connector, the insulating gel is forced into an interior cavity of the connector thus insulating wires being crimped.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
53 words
An electrical crimp connector, comprising: means for piercing electrical conductors; a crimping body surrounding the piercing means; an insulating envelope disposed around the crimping body; means for forming a space between an outer surface of the crimping body and an inner surface of the insulating envelope; and a gel disposed within the space.
Claim 2
Dependent Claim
53 words
An electrical crimp connector, comprising: means for piercing electrical conductors; a crimping body surrounding the piercing means; an insulating envelope disposed around the crimping body; means for forming a space between an outer surface of the crimping body and an inner surface of the insulating envelope; and a gel disposed within the space.
Claim 3
Dependent Claim
41 words
The connector of claim 1, the crimping body, piercing means, and insulating sleeve having a substantially cylindrical shape, one axial end of the crimping body being closed and the other axial end being open, the envelope having both axial ends open.
Claim 4
Dependent Claim
36 words
The connector of claim 1, the crimping body and piercing means having holes through side walls thereof to allow the gel to flow into a central cavity of the piercing means upon crimping of the connector.
Claim 5
Dependent Claim
35 words
The connector of claim 3, the piercing means being capable of piercing through insulation of an electrical conductor, the crimping body being made of metal, and the insulating envelope being made of a polymeric material.
Claim 6
Dependent Claim
48 words
The connector of claim 1, the gel being disposed in the space between the crimping body and the envelope by injecting a gel precursor under pressure at one axial end of the envelope, excess gel precursor leaving the connector through an opposite open axial end of the envelope.
Claim 7
Dependent Claim
16 words
The connector of claim 3, the envelope being recoverable and being recovered around the crimping body.
Claim 8
Dependent Claim
17 words
The connector of claim 5, the gel precursor being cured subsequent to being injected into the envelope.
Claim 9
Dependent Claim
18 words
The connector of claim 1, the forming means comprising dimples disposed between the crimping body and the envelope.
Claim 10
Dependent Claim
15 words
The connector of claim 8, the dimples being an integral part of the crimping body.
Claim 11
Dependent Claim
14 words
The connector of claim 8, the dimples being an integral part of the envelope.
Claim 12
Dependent Claim
26 words
The connector of claim 1, the gel having a cone penetration between 100 and 350 (10 -1 mm), and an ultimate elongation of at least 200%.
Claim 13
Dependent Claim
16 words
The connector of claim 11, the cone penetration being between 200 and 300 (10 -1 mm).
Claim 14
Dependent Claim
16 words
The connector of claim 12, the cone penetration being between 240 and 270 (10 -1 mm).
Claim 15
Dependent Claim
35 words
The connector of claim 1, the gel being disposed within the space in such a manner that a central cavity of the piercing means is substantially void of the gel prior to crimping the connector.
Claim 16
Dependent Claim
48 words
The connector of claim 1, the envelope having an open axial end confronting a closed axial end of the crimped body for allowing access to the crimping body so that a test probe can be connected to the crimping body to determine electrical connection with wires being crimped.
