ABSTRACT:
A clock spring interconnector provides electrical connection between a rotating and nonrotating electrical circuit. In the interconnector, an outer housing defines a fist aperture extending therethrough. A rotor member occupies the first aperture in rotational relation to it. First conductor wire means are carried by the outer housing, while second conductor wire means are carried by the rotor member. Coiled conductor means are loosely coiled in a plurality of coils about the rotor member within the outer housing, with the coiled conductor means being connected at respective ends to the first and second conductor wires. The rotor member defines a second aperture extending through it in generally coaxial relation with the first aperture. In accordance with this invention, at least a part of the second aperture is of noncircular cross-section, with the outer housing defining a portion projecting into the noncircular part of the second aperture, to limit the rotation of the rotor member to provide rotational orientation of it until the projecting portion is removed.
