ABSTRACT:
An electrical, multi-wire interconnection between the hinged, movable door (3) of a vehicle and its main body (7) across the hinge gap in the form of a planar cable array (10) having a flat, laterally extended cross-section (FIG. 3), provided with a modular trim panel (3A). It includes at its distal, "A" pillar end an end connector (5A), which mates with an electrical connector (5B) in the "A" pillar. The cable fits in an embossed channel, to which it is like configured, in the door frame. When the door is closed, it is sealingly sandwiched between the metal door frame member (3B) and the rubber door seal on the vehicle body. The door may include a remote multiplexing (remux) unit (30), allowing the use of, for example, as few as about eight wires (11), even though the door is fully powered. The planar cable array can be pre-manufactured as, for example, flat ribbon cable, or made on site using a hardenable plastic (FIG. 5A) or tape-type (FIG. 5B) material during a pre-assembly, modular door panel operation off from the regular main assembly line of the final, automotive manufacturing operation. In its extent between the door and the vehicle body, the plane of the cable is vertically aligned and folds back unto itself when the door is closed (FIG. 2A) and has no significant, excess slack when the door is fully open (FIG. 2B). The wires can be included in the same plane or in up to about three, parallel layers.
