Abstract

Abstract A peelaway flat cable for providing electrical connection to a missile. First and second flat cables, each having a plurality of spaced conductors, are electrically connected together and are bonded to one another. A breakaway joint is provided in the cable to provide ready separation after the cable has performed its desired function.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 308 words
A peelaway flat cable assembly for providing a separable electrical connection to a movable store comprising, a first thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said thin and wide flat cable, a second thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said second thin and wide flat cable and equal in number to the number of spaced conductors in said first flat cable, one wide end portion of said first thin and wide flat cable being overlapped and bonded to one wide end portion of said second thin and wide flat cable and positioned such that said spaced conductors in said first flat cable are aligned above said spaced conductors in said second flat cable, a first thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides below said plurality of conductors and a second thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides above said plurality of conductors whereby all of said conductors are positioned between said first and second metallic shields, a plurality of holes in said insulating material in the overlapped areas of said first and second flat cables, one hole communicating with each conductor to provide passageways between aligned conductors in said first flat cable and conductors in said second flat cable and solidified solder in each said passageway and in electrical contact with each aligned pair of conductors, and a plurality of perforations through said wide side of said first metallic shield for providing a breakaway joint for severing said flat cable assembly when a force is applied thereto.
Claim 2
Dependent Claim 308 words
A peelaway flat cable assembly for providing a separable electrical connection to a movable store comprising, a first thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said thin and wide flat cable, a second thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said second thin and wide flat cable and equal in number to the number of spaced conductors in said first flat cable, one wide end portion of said first thin and wide flat cable being overlapped and bonded to one wide end portion of said second thin and wide flat cable and positioned such that said spaced conductors in said first flat cable are aligned above said spaced conductors in said second flat cable, a first thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides below said plurality of conductors and a second thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides above said plurality of conductors whereby all of said conductors are positioned between said first and second metallic shields, a plurality of holes in said insulating material in the overlapped areas of said first and second flat cables, one hole communicating with each conductor to provide passageways between aligned conductors in said first flat cable and conductors in said second flat cable and solidified solder in each said passageway and in electrical contact with each aligned pair of conductors, and a plurality of perforations through said wide side of said first metallic shield for providing a breakaway joint for severing said flat cable assembly when a force is applied thereto.
Claim 3
Dependent Claim 36 words
A peelaway flat cable assembly for providing a separable electrical connection to a movable store as set forth in claim 1 wherein said first and second thin and wide flat cables are bonded with waterproof cement.
Claim 4
Dependent Claim 268 words
A peelaway flat cable assembly for providing a separable electrical connection to a movable store comprising, a first thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said thin and wide flat cable, a second thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said second thin and wide flat cable and equal in number to the number of spaced conductors in said first flat cable, one wide end portion of said first thin and wide flat cable being overlapped and bonded to one wide end portion of said second thin and wide flat cable and positioned such that said spaced conductors in said first flat cable are aligned above said spaced conductors in said second flat cable, a first thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides below said plurality of conductors and a second thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides above said plurality of conductors whereby all of said conductors are positioned between said first and second metallic shields, means in the overlapped areas of said first and second flat cables for electrically connecting each aligned pair of conductors, and a plurality of perforations through said wide side of said first metallic shield for providing a breakaway joint for severing said flat cable assembly when a force is applied thereto.
Claim 5
Dependent Claim 268 words
A peelaway flat cable assembly for providing a separable electrical connection to a movable store comprising, a first thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said thin and wide flat cable, a second thin and wide flat cable of insulating material having a plurality of parallel conductors spaced apart therein along the wide dimension of said second thin and wide flat cable and equal in number to the number of spaced conductors in said first flat cable, one wide end portion of said first thin and wide flat cable being overlapped and bonded to one wide end portion of said second thin and wide flat cable and positioned such that said spaced conductors in said first flat cable are aligned above said spaced conductors in said second flat cable, a first thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides below said plurality of conductors and a second thin and wide metallic shield having a wide side bonded to both said first and second flat cables on the wide sides above said plurality of conductors whereby all of said conductors are positioned between said first and second metallic shields, means in the overlapped areas of said first and second flat cables for electrically connecting each aligned pair of conductors, and a plurality of perforations through said wide side of said first metallic shield for providing a breakaway joint for severing said flat cable assembly when a force is applied thereto.
Claim 6
Dependent Claim 36 words
