An engaging body has first and second engaging walls in which a space between the respective inner wall surfaces is defined as an accommodation space of the engaged body, an engaging protrusion protruding from the inner wall surface of the second engaging wall and capable of locking the engaged protrusion on the removal direction side, and a third engaging wall disposed between the first and second engaging walls.

A positive common line and a negative common line are connected to a power source connector connected to a battery pack. First filters are provided on these two common lines, respectively. The positive common line is branched into a positive front line and a positive rear line. The negative common line is branched into a negative front line and a negative rear line. These two front lines are connected to a front power connector that is connected to a front power control unit. These two rear lines are connected to a rear power connector that is connected to a rear power control unit. It is possible to suppress electromagnetic noise on common lines.

Provided is an electrical connection cassette with which it is possible to freely expand a device and add functions in accordance with the size of free space. An electrical connection cassette is provided with: a circuit board; and first connection terminals and second connection terminals mounted on the circuit board and having terminal shapes that can be engaged with each other. In a state with a terminal connection direction oriented in a predetermined direction with respect to the circuit board, the first connection terminals are disposed on the side of one main surface of the circuit board, and in a state with a terminal connection direction oriented in a direction parallel to the predetermined direction, the second connection terminals are disposed near the other main surface of the circuit board.

A bracket assembly for a relay box for a vehicle includes a first bracket member and a second bracket member. The first bracket member is configured to be mounted to a frame of the vehicle. The first bracket member is configured to receive the relay box in an installed position. The second bracket member is connected to the first bracket member. A gap is defined between the first bracket member and the second bracket member. The gap is configured to receive an electrical wiring harness connected to the relay box to support the relay box prior to the relay box being mounted in the installed position.

A novel electrical box to house one or more ISO micro relays, is adapted to support IP67 and IP69K Ingress Protection ratings. The housing of the electrical box is molded with blade sockets that correspond to blade positions of the ISO micro relay. The housing is also molded with terminal seats and cylindrical openings which vary, depending on the blade socket, enabling terminals of different sizes, orientations, and positions relative to the respective blades, to be easily inserted into the back of the housing. The resulting position of the terminals ensures that electrical connections to the ISO micro relay are made and ingress protection of components inside the electrical box is ensured.

A power relay assembly is provided. A power relay assembly according to an exemplary embodiment of the present invention comprises: a support plate having at least one electric element mounted on one surface thereof and including a plastic material having heat dissipation and insulation properties; and at least one bus bar electrically connected to the electric element and partially embedded in the support plate. Due to these features, since heat generated from the bus bar and the electric element is dissipated to the outside through the support plate, it is possible to prevent performance deterioration due to heat and breakage of electronic components.

In one aspect of the present disclosure, an induction hub is disclosed for use in powering components in a vehicle. The induction hub includes a source coil; first and second receiver coils having first and second conductive portions, respectively; and at least one isolation member that is positioned between the first and second conductive portions. The receiver coils are separated from the source coil such that, upon being energized by a power source, the source coil creates an induced electromagnetic field (EMF) and an electrical current in the receiver coils, which are in electrical communication with at least one component in the vehicle to thereby deliver power from the receiver coils to the at least one component. The at least one isolation member includes a material that is electrically nonconductive and electromagnetically permeable so as to physically and electrically separate the receiver coils without impacting the induced EMF.

An electric connection box includes a housing having an opening formed by side walls, a lock protruding plate, a lid to be attached to the housing, a hook, a lock portion, a protective wall, lock pieces and slits. The protective wall is configured to, when the lid is attached to the housing, cover a cable connection portion provided on the second side wall. The lock pieces extend in parallel to the protective wall and extend from the protective wall toward a first direction. The pair of slits respectively includes a receiving opening to, when the lid is attached to the housing, accommodate respective one of the pair of lock pieces, the pair of slits being to receive the lock pieces when engagement at the lock portion is carried out. The receiving opening opens, when the lid is attached to the housing, toward a second direction.

An electrical junction box includes a frame and a cassette block. The frame has a side wall, the frame having a first opening and a second opening provided at two ends of the side wall. The cassette block is to be attached to the frame from the first opening along a first direction and electric wires are drawn out along a second direction when the cassette block is attached to the frame, the first direction being a direction toward the second opening from the first opening, the second direction being another direction toward the first opening from the second opening. The cassette block has a jig engagement portion configured such that a jig inserted into the cassette block from a side of the second opening engages with the jig engagement portion and the cassette block is drawn into the frame by the jig moving in the first direction.

An electrical junction box includes a box body, a housing member fixed to a fixing surface that is set on a portion of an inner surface of the box body, and an electronic component that is housed in the housing member and to which a wire W is to be connected. The housing member includes a wire lead-out surface from which the wire W connected to the electronic component is to be led out, a component housing portion that is a space for housing the electronic component and that includes an opening portion that opens in the wire lead-out surface, and an extended wall portion that is located on the fixing surface side relative to the component housing portion and extends to a side of the opening portion in an opening direction thereof relative to the wire lead-out surface.
