Abstract
Abstract A multi-pin plug and socket electrical connector in which adjacent pins are sealed from each other at the interface by an elastomeric sheet. The sheet extends over the entire interface with each pin extending through a hole in the sheet. Each hole is surrounded by a O-ring integral with the sheet. The sheet may extend within each O-ring to make contact with the pin. The pins are sealed at their opposite, i.e. wire ends by individual elastomeric seals in the pin bores.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A two-part electrical connector, comprising: first and second parts each having insulating bores; first and second sets of longitudinal conductive elements housed in respective ones of said insulating bores, conductive elements of one set mating with respective conductive elements of the other set to form electrical connections when said parts are brought together, an interface being defined between said parts in use; an insulating elastomeric sheet disposed at the interface between said parts, each connecting pair of elements extending through a respective hole in said sheet; and an O-ring surrounding each hole, each said O-ring being integral with said sheet and of greater thickness than said sheet such that said O-ring stands proud of said sheet on both sides of said sheet, so that, in use, adjacent connecting pairs of elements are sealed from each other across the interface.
Claim 2
Dependent Claim
139 words
A two-part electrical connector, comprising: first and second parts each having insulating bores; first and second sets of longitudinal conductive elements housed in respective ones of said insulating bores, conductive elements of one set mating with respective conductive elements of the other set to form electrical connections when said parts are brought together, an interface being defined between said parts in use; an insulating elastomeric sheet disposed at the interface between said parts, each connecting pair of elements extending through a respective hole in said sheet; and an O-ring surrounding each hole, each said O-ring being integral with said sheet and of greater thickness than said sheet such that said O-ring stands proud of said sheet on both sides of said sheet, so that, in use, adjacent connecting pairs of elements are sealed from each other across the interface.
Claim 3
Dependent Claim
31 words
A two part electrical connector according to claim 1 wherein said sheet extends within each said O-ring such that said sheet is in contact with each said connecting pair of elements.
Claim 4
Dependent Claim
36 words
A two-part electrical connector according to claim 1 wherein said sheet extends beyond said interface around and in close contact with the sides of one said part such that said sheet is supported by said part.
Claim 5
Dependent Claim
54 words
A two-part electrical connector according to claim 1 comprising a respective elastomeric insulating seal disposed towards the rear end of each bore distant from said interface and surrounding each conductive element said seal being in sealing contact with said bore and having at least one annular ridge in sealing contact with said conductive element.
Claim 6
Dependent Claim
54 words
A two-part electrical connector according to claim 1 comprising a respective elastomeric insulating seal disposed toward the rear end of each bore distant from said interface and surrounding each conductive element, said seal being in sealing contact with said conductive element and having at least one annular ridge in sealing contact with said bore.
Claim 7
Dependent Claim
24 words
A two-part electrical connector according to claim 5 wherein said seal is so shaped as to clip into a recess in said conductive element.
Claim 8
Dependent Claim
24 words
A two-part electrical connector according to claim 5 wherein said seal is so shaped as to engage a retaining shoulder on said conductive element.
