A vehicular circuit body includes a trunk line that includes a power source line and a communication line, and that is routed in a vehicle body; and a plurality of control boxes that are disposed in a distribution manner along the trunk line. The trunk line includes a first trunk line portion extending in a front-and-rear direction of the vehicle body and a second trunk line portion extending in a leftward-and-rightward direction of the vehicle body. The plurality of control boxes include a branch control box that connects the first trunk line portion and the second trunk line portion, and distributes power from one of the first trunk line portion and the second trunk line portion to the other one.

A protective earthing contact for connecting a protective earth line with an electrically conductive carrier element in an the electrically conducting manner, wherein the protective earthing contact has a base portion, wherein two side elements project from the base portion and a respective side element has an upper region, wherein the upper regions have a latching region for clamping the protective earthing contact onto the carrier element and wherein at least one side element has a protective earth contact element for making contact to the carrier element in an electrically conducting manner. Each of the upper regions has a contact-making region, wherein the latching region and the protective earth contact element are substantially arranged at the same height in relation to the base portion.

Trace wire connectors that include a cover that can be attached to a base and used to electrically interconnect two or more tracer wires without having to remove insulation from the tracer wires. The cover has multiple portals that permit one or more tracer wires to pass into an inner cavity of the cover. The base has multiple cradles on which tracer wires passing into the cavity can rest. The cover can be oriented relative to the base for use with a through tracer wire and a dead-end tracer wire, or for use with multiple dead-end tracer wires.

A connector unit is provided with a first connector, a second connector, a plurality of wires for electrically connecting the first connector and the second connector, an electromagnetic shield member for covering the plurality of wires, an electromagnetic shield cover fixed to the first connector while covering the first connector, and an electrically conductive bracket to be fixed to a ground target part while being separated from the second connector. The electromagnetic shield cover includes a cover body and a cover fixing plate to be fixed to the cover body. One end part of the electromagnetic shield member is fixed to the electromagnetic shield cover by being sandwiched by the cover body and the cover fixing plate. The electrically conductive bracket is fixed to another end part of the electromagnetic shield member. The electrically conductive bracket includes a reinforcing rib projecting in a thickness direction of the electrically conductive bracket.
