  • Patent number: 5498164
    Abstract: An electrical connector for a steering wheel which utilizes a non-wear electrical interconnection characterized by terminals of a base terminal bus and terminals of a rotor terminal bus being physically separated yet mutually electrically connected via contact with an electrically conductive liquid situated in one or more annular chambers located between outer faces of a rotor plate and a base plate. The rotor terminal bus is connected with the rotor plate and the base terminal bus is connected with the base plate. The base and rotor plates are connected together in a manner that permits relative rotation therebetween. The electrically conductive liquid is provided in each of the annular chambers by being preferably injected through a hollow capillary of at least one of the rotor and base terminals of each annular chamber, and then sealed, such as by solder. Preferred electrically conductive liquids include mercury or silicone.

  • Patent number: 5367750
    Abstract: A clip which secures wiring to a base structure, composed of a head for holding the wiring and a stanchion for connecting the head with a base structure. The head is provided with an upper portion and hingably connected lower portion. The lower portion is provided with a wiring seat, a flexible retention arm and a first toothed surface member. The upper portion is provided with a flexible biasing arm, an abutment arm and a second toothed surface member. A retainer arm is connected with the lower portion of the head for preventing unintentional disengagement of the first and second toothed members. In operation, the upper portion is pivoted on the hinge toward the lower portion, during this movement, the first and second toothed surface members will mutually engage in a ratchet-like manner, while the retention arm is pressed against the wiring by abutting action of the biasing arm. Depending on the wiring diameter the abutment arm may abuttably engage the wiring.
