Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A connector adapted for use with multiple conductor cables comprising facing outer bearing surfaces located on two clamp blocks disposed in register with each other, inner bearing surfaces located on a center block in facing relationship to said outer bearing surfaces to form two conductor-accommodating recesses, contact members for extending electrical paths from one recess to the other, and means for urging said clamp blocks towards said center block to compress conductors located in said recesses against said contact members, CHARACTERIZED IN THAT each contact member is a unitary wire extending internally through said center block, has deflectable sections located in each recess for engaging conductors pressed between said inner and outer bearing surfaces, and has an intermediate section bearing against a solid interior portion of said center block whereby electrical contact is readily made between conductors located in opposite recesses.
Claim 2
Dependent Claim
141 words
A connector adapted for use with multiple conductor cables comprising facing outer bearing surfaces located on two clamp blocks disposed in register with each other, inner bearing surfaces located on a center block in facing relationship to said outer bearing surfaces to form two conductor-accommodating recesses, contact members for extending electrical paths from one recess to the other, and means for urging said clamp blocks towards said center block to compress conductors located in said recesses against said contact members, CHARACTERIZED IN THAT each contact member is a unitary wire extending internally through said center block, has deflectable sections located in each recess for engaging conductors pressed between said inner and outer bearing surfaces, and has an intermediate section bearing against a solid interior portion of said center block whereby electrical contact is readily made between conductors located in opposite recesses.
Claim 3
Dependent Claim
17 words
A connector in accordance with claim 1 wherein each of said contact members has an S-shaped configuration.
Claim 4
Dependent Claim
41 words
A connector in accordance with claim 2 wherein said deflectable sections are located at the opposite ends of each connector member and extend into said recesses to exert a pretensioned force against conductors clamped between said inner and outer bearing surfaces.
Claim 5
Dependent Claim
55 words
A connector in accordance with claim 2 wherein one of said clamp blocks also includes a number of fixed contacts disposed in a row and said contact members are aligned in register with said fixed contact members so as to engage said fixed contact members when said inner and outer bearing surfaces are urged together.
Claim 6
Dependent Claim
92 words
A connector for flat cables comprising two clamp blocks disposed on opposite sides of a center block, said clamp blocks and said center block having bearing surfaces located in facing relationship to each other to form a pair of cable-accommodating recesses and said center block including a group of contact members in which each contact member has an X-shaped configuration, is made from a single unitary piece of wire, has an end section projecting into each of said recesses and includes a center section passing through the interior of said center block.
Claim 7
Dependent Claim
92 words
A connector for flat cables comprising two clamp blocks disposed on opposite sides of a center block, said clamp blocks and said center block having bearing surfaces located in facing relationship to each other to form a pair of cable-accommodating recesses and said center block including a group of contact members in which each contact member has an X-shaped configuration, is made from a single unitary piece of wire, has an end section projecting into each of said recesses and includes a center section passing through the interior of said center block.
Claim 8
Dependent Claim
19 words
A connector in accordance with claim 5 wherein eacH contact member is made from a piece of preplated wire.
Claim 9
Dependent Claim
50 words
A connector in accordance with claim 5 wherein the midpoint of each contact member is located in the center of said center block and the ends of said contact member extend above the surface of said center block to form a pair of serially aligned contact surfaces in each recess.
Claim 10
Dependent Claim
22 words
A connector in accordance with claim 7 wherein at least two of said ends have hook-shaped deflectable sections projecting into said recesses.
