Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
226 words
A rotation lock and wipe connector comprising: a biasing member, said biasing member being elongated and having a longitudinal opening along the length thereof, the biasing member being generally C-shaped having a center portion and arm portions terminating in said opening, said opening being sufficiently wide to allow the insertion of a circuit board at a first angle with little effort, rotation of such a circuit board with respect to said opening to a second angle changing the effective width of said opening with respect to a circuit board; and flexible circuitry having first and second sets of parallel-spaced electrical conductors, at least a portion of said flexible circuitry mounted about said biasing member, said conductors being oriented generally perpendicular to said opening, said electrical conductors terminating in first and second sets of electrical contacts, said first set of contacts positioned on one side of said opening and said second set of contacts positioned on the other side of said opening, rotation of a circuit board within said opening interconnecting such a circuit board with said electrical contacts and bending at least one of said arm portions of said biasing member, movement of said arm members causing a wiping action between said electrical contacts and the circuit board inserted within said opening while simultaneously creating a normal force on said electrical contacts thus ensuring electrical integrity.
Claim 2
Dependent Claim
226 words
A rotation lock and wipe connector comprising: a biasing member, said biasing member being elongated and having a longitudinal opening along the length thereof, the biasing member being generally C-shaped having a center portion and arm portions terminating in said opening, said opening being sufficiently wide to allow the insertion of a circuit board at a first angle with little effort, rotation of such a circuit board with respect to said opening to a second angle changing the effective width of said opening with respect to a circuit board; and flexible circuitry having first and second sets of parallel-spaced electrical conductors, at least a portion of said flexible circuitry mounted about said biasing member, said conductors being oriented generally perpendicular to said opening, said electrical conductors terminating in first and second sets of electrical contacts, said first set of contacts positioned on one side of said opening and said second set of contacts positioned on the other side of said opening, rotation of a circuit board within said opening interconnecting such a circuit board with said electrical contacts and bending at least one of said arm portions of said biasing member, movement of said arm members causing a wiping action between said electrical contacts and the circuit board inserted within said opening while simultaneously creating a normal force on said electrical contacts thus ensuring electrical integrity.
