Patent ID: 8491345

Claim:
A method of improving electrical transmission through an electrical contact assembly comprising an insertion object having a longitudinal axis, a housing having a bore receiving the insertion object therein, and plurality of coils of a canted coil spring in electrical communication with the housing and the insertion object, the method comprising: reducing electrical resistance between the housing and the insertion object by providing an electrical path length between a first contact point, defined by a contact between the insertion object and a coil that contacts the insertion object, and a second contact point, defined by a contact point between the housing and the coil that contacts the insertion object, reducing the electrical path length by about 10% to 50% compared to a direct path length of two contact points located along a line that is orthogonal to the longitudinal axis of the insertion object by: providing a groove in the bore of the housing or on the insertion object, said groove having two generally parallel side walls and a bottom wall located between the two generally parallel side walls; and providing an axial canted coil spring for the canted coil spring in the groove; and biasing the axial canted coil spring against the two generally parallel side walls of the groove but spaced from the bottom wall to define two contacts for each contacting coil with the groove, the two contacts for each contacting coil with the groove increase a number of contacts for each contacting coil with the groove from a single contact with the bottom wall to two contacts with the two generally parallel side walls.
