Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
69 words
A method of manufacture of a contact assembly having a plurality of contact springs comprising: providing a support having a like plurality of spaced apart conductive lands; providing a helical spring having a like plurality of turns; disposing each of said turns adjacent a respective one of said lands; mechanically and electrically fixing a portion of each of said turns to the respective adjacent land; and cutting each turn.
Claim 2
Independent Claim
69 words
A method of manufacture of a contact assembly having a plurality of contact springs comprising: providing a support having a like plurality of spaced apart conductive lands; providing a helical spring having a like plurality of turns; disposing each of said turns adjacent a respective one of said lands; mechanically and electrically fixing a portion of each of said turns to the respective adjacent land; and cutting each turn.
Claim 3
Dependent Claim
16 words
A method according to claim 1 wherein: said lands are uniformly spaced apart in a row.
Claim 4
Dependent Claim
13 words
A method according to claim 2 wherein: said turns are uniformly spaced apart.
Claim 5
Dependent Claim
25 words
A method according to claim 1 wherein: a longitudinal cut is made through one side of said helical spring to sever each turn in sequence.
Claim 6
Dependent Claim
26 words
A method according to claim 4 wherein: said longitudinal cut is made adjacent the portion of each of said turn which is fixed to said land.
Claim 7
Dependent Claim
40 words
A method according to claim 1 wherein: a guide having a like plurality of slots is disposed over said plurality of turns, each turn entering into and extending beyond a respective slot, and said guide is fixed to said support.
Claim 8
Dependent Claim
80 words
A contact assembly having a plurality of contact springs made according to the process of: providing a support having a like plurality of spaced apart conductive lands; providing a helical spring having a like plurality of turns; disposing each of said turns adjacent a respective one of said lands; mechanically and electrically fixing a portion of each of said turns to the respective adjacent land; and cutting each turn to form a respective one of said plurality of contact springs.
Claim 9
Dependent Claim
80 words
A contact assembly having a plurality of contact springs made according to the process of: providing a support having a like plurality of spaced apart conductive lands; providing a helical spring having a like plurality of turns; disposing each of said turns adjacent a respective one of said lands; mechanically and electrically fixing a portion of each of said turns to the respective adjacent land; and cutting each turn to form a respective one of said plurality of contact springs.
Claim 10
Dependent Claim
40 words
A contact assembly according to claim 7 further including: a guide having a like plurality of slots disposed over said plurality of turns, each turn disposed in and extending beyond its respective slot, said guide being fixed to said support.
Claim 11
Dependent Claim
58 words
A contact assembly comprising: a support having a plurality of spaced apart conductive lands; and a like plurality of turns of a helical spring, each turn cut and spaced from its adjacent turn and disposed adjacent to and mechanically and electrically fixed to a respective one of said plurality of lands, each turn forming a substantially C-shaped spring.
Claim 12
Dependent Claim
58 words
A contact assembly comprising: a support having a plurality of spaced apart conductive lands; and a like plurality of turns of a helical spring, each turn cut and spaced from its adjacent turn and disposed adjacent to and mechanically and electrically fixed to a respective one of said plurality of lands, each turn forming a substantially C-shaped spring.
Claim 13
Dependent Claim
40 words
A contact assembly according to claim 9 further including: a guide having a like plurality of slots disposed over said plurality of turns, each turn disposed in and extending beyond its respective slot, said guide being fixed to said support.
