Abstract
Abstract An electrical conductor feed through and seal is provided which allows for the passing of electrical conductors, imbedded in flextape, from outside an enclosure to within an enclosure without the use of headers. Flextapes are used which are configured, in part, to match the profile of the mating surfaces of the enclosure. The tapes are bonded together at this point by a suitable adhesive. An elastomeric material of suitable durometer is inserted between the bonded flextapes and each mating surface, so that when the mating surfaces are drawn together, the required seal is formed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
A device for providing an electrical conductor feed through and seal between the mating surfaces of an enclosure which comprises: a plurality of flexible electrical cables, each having a portion thereof extending without said enclosure, another portion extending within said enclosure and a third portion substantially aligned with the third portion of the other said flexible cables; said aligned third portions configured such that they are continuously interposed between the mating surfaces of said enclosure, bonding adhesive interposed between said third portions for bonding each layer to the ones juxtaposed thereto; and an elastomeric material disposed between and contiguous with each of the outermost third portions and the mating surfaces of said enclosure.
Claim 2
Independent Claim
113 words
A device for providing an electrical conductor feed through and seal between the mating surfaces of an enclosure which comprises: a plurality of flexible electrical cables, each having a portion thereof extending without said enclosure, another portion extending within said enclosure and a third portion substantially aligned with the third portion of the other said flexible cables; said aligned third portions configured such that they are continuously interposed between the mating surfaces of said enclosure, bonding adhesive interposed between said third portions for bonding each layer to the ones juxtaposed thereto; and an elastomeric material disposed between and contiguous with each of the outermost third portions and the mating surfaces of said enclosure.
Claim 3
Dependent Claim
37 words
The device of claim 1 where each of said mating surfaces has a protrusion extending from the outer perimeter thereof to thereby restrain the outward extrusion of said elastomeric material when said mating surfaces are drawn together.
Claim 4
Dependent Claim
24 words
The device of claim 2 where the elastomeric material has a durometer greater than 20 and less than 75 on the Shore A scale.
Claim 5
Dependent Claim
12 words
The device of claim 3 where the elastomeric material is Butyl rubber.
Claim 6
Dependent Claim
23 words
The device of claim 1 which includes a layer of polyimide bonded to the outboard side of each of the outermost third portions.
Claim 7
Dependent Claim
21 words
The device of claim 5 where the elastomeric material is bonded to the outboard side of each of said polyimide layers.
