An apparatus for providing power to a vehicle's electric power system comprises a converter (602) for converting electric input electricity having an input voltage into output electricity having an output voltage. A sense line (612) is provided for electrically connecting a control unit (611) to the vehicle's electric power system. A power line (613) is for connecting an output of the converter (602) in parallel to the vehicle's electric power system. The control unit (611) is configured to detect a running state of an alternator (201) of the vehicle based on a measurement of a signal on the sense line (612) and control the converter (602) to set the output voltage in dependence on the detected running state.

Flat surfaces out of two flat surfaces of each of flat electrical connection bodies of a relay bus bar and a bus bar of an electronic component are mating surfaces brought into contact with each other by a fixing structure. At least one of the flat electrical connection bodies of the relay bus bar and the bus bar applies a reaction force accompanying the elastic deformation to the other flat electrical connection body, to which the one flat electrical connection body is to be connected, in a state in which the flat electrical connection body of the bus bar at an accommodation completion position in a housing has not been connected to the relay bus bar. The housing includes a receiving portion receiving a force applied to the flat electrical connection body of the bus bar from the flat electrical connection body of the relay bus bar.

On an outer circumferential edge of a closing plate, an elastic fitting portion protruding to an outer side of an inner circumferential edge of a service hole and fitting with the inner circumferential edge projects with a thickness larger than the plate thickness of the closing plate and extends in the circumferential direction of the outer circumferential edge. The elastic fitting portion is provided with an inner circumferential edge accommodating recessed groove that opens in the center of a protruding end surface of the elastic fitting portion and extends in the circumferential direction to accommodate the inner circumferential edge of the service hole, and the inner circumferential edge of the service hole is clamped between a pair of elastic clamping pieces that face each other with the inner circumferential edge accommodating recessed groove interposed between the pair of elastic clamping pieces.

A terminal block includes a lower bus bar and an upper bus bar that overlap each other at overlap portions and an insulating middle cover disposed between the overlap portion of the lower bus bar and the overlap portion of the upper bus bar. The lower bus bar and the upper bus bar are provided with their respective ones of first to fourth terminals exposed from the middle cover, at positions different from the overlap portions and the first to fourth terminals are disposed at positions radially spaced apart from the overlap portions.

In an electric work vehicle, a power feeding assembly which connects a battery device to a power controller unit so as to feed power includes a fixed connector which is fixed to the battery device and electrically connected to the battery device, a cable harness connected to a power controller unit, and a free connector which is connected to an end of the cable harness and connectable to a fixed connector, and a connecting operation tool is configured to be movable the free connector between the connecting position in which the free connector is connected to the fixed connector and the detaching position.

A motor controller is disclosed. The motor controller according to one embodiment of the present invention comprises a first electronic control unit which comprises a first substrate and a first connector having a first identification member and coupled to the first substrate and controls a motor, a second electronic control unit which comprises a second substrate and a second connector having a second identification member different from the first identification member and coupled to the second substrate and controls the motor, and a first heat radiation member of which one surface is coupled to the first electronic control unit and the other surface is coupled to the second electronic control unit, and which comprises a first interference member formed at a position at which the first interference member is not interfered with by the first identification member but is interfered with by the second identification member such that the one surface is not coupled to the second electronic control unit and has a plate shape.

A self-aligning mechanical mount and electrical connection system for an electronic module comprises a mechanical mount assembly configured to be integrated into or attached to a base frame and defining a mount connection position assurance (CPA) feature for self-aligning and securing of the electronic module therein, and an electrical connection assembly configured to be integrated into or attached to the mechanical mount assembly and comprising a modular electrical connector (i) being electrically connected to an electrical backbone wire cable and (ii) defining a connector CPA feature for self-aligning the modular electrical connector with a corresponding electrical connector integrated into or attached to the electronic module when the electronic module is secured in the mechanical mount assembly.

A flat flexible cable (FFC) assembly, which includes a multi-FFC cable having a plurality of FFC films arranged in a layered form and an insulation tube for surrounding the plurality of FFC films, and a pair of high current terminals mounted to respective ends of the multi-FFC cable.

A wire harness for routing in a vehicle in which an exhaust pipe through which exhaust gas flows is attached under a floor, the wire harness including: a first wire to be routed alongside the exhaust pipe; and a second wire to be routed on an opposite side of the first wire to the exhaust pipe, wherein the first wire has: a conductor and an insulation coating covering an outer periphery of the conductor; and a metal tube housing the conductor and the insulation coating.

A wire harness including an electric wire; a cover that covers an outer circumferential surface of the electric wire; and a clamp for fixing the electric wire to a vehicle body, wherein: a surface of the cover that is provided on a side opposite to the electric wire includes an uneven surface with a plurality of irregularities, and the clamp includes: an elastic member that is made of an elastic body and is brought into contact with the uneven surface; and a fixing member that presses the elastic member against the uneven surface and is fixed to the vehicle body.
