Abstract
Connector device for connecting the lamp circuit of a trailer vehicle with the lamp circuit of a tractor vehicle comprising a circular base member having a hub, circular walls, and different diameter non-conducting plastic rings rotatably disposed one within the other on the base member. Each ring has a recessed metal strip along its underside, a convex dimple, and a positioning hole in its upper surface. Contact riders radially disposed on the base member establish electrical contact with the metal strips of each ring and are connected with conductors which are attachable to the lamp circuit of one of the vehicles. Contactor plates radially disposed on the base member have concave dimples adapted for receiving the convex dimples of the rings. A second set of electrical conductors are connected to the contactor plates and run to the lamp circuit of the other vehicle. A face plate is rotatably disposed over the rings and has a plurality of positioning holes, such that a program pin can be inserted through the face plate for rotation of each of the rings to a desired contacting position.
