Provided is an electrical connection box including a housing casing for housing a relay, and a heat transfer sheet for transferring heat from the relay to the housing casing, the electrical connection box including: a bus bar provided between a top surface and an inside surface that correspond to each other in the housing casing so as to oppose the top surface and the inside surface; a first holding portion protruding from the inside surface and holding the bus bar via the heat transfer sheet; and a second holding portion protruding from the top surface and holding the bus bar.

Electrical connection box

Provided is an electrical junction box that can be reduced in size by accommodating a high-voltage bus bar and a low-voltage bus bar in a space-efficient manner. The electrical junction box is an electrical junction box for a vehicle including a housing that accommodates a high-voltage bus bar for high voltages and a low-voltage bus bar for low voltages, in which the low-voltage bus bar is attached to a top plate of the housing, the high-voltage bus bar is attached to a bottom plate facing the top plate, and the high-voltage bus bar and the low-voltage bus bar are disposed overlapping each other with a clearance distance therebetween in an up-down direction.

Electrical junction box

An electrical connection box for installation in a vehicle includes a bus bar to electrically and thermally interconnect a plurality of electrical components electrically connected to a power storage device or in-vehicle load installed in the vehicle, a casing to house the plurality of electrical components and the bus bar, and an insulating heat dissipation member thermally connected to the bus bar and the casing, with at least two of the plurality of electrical components being disposed adjacent to each other, and the bus bar dissipating heat from the two electrical components via the heat dissipation member.

Provided is a circuit structure having a novel structure that allows heat from a heat-generating component to be dissipated more efficiently. A circuit structure includes: a heat-generating component that generates heat when energized; energization bus bars that are connected to connection portions of the heat-generating component; cooling members that are formed separately from the energization bus bars, and are connected to the connection portions of the heat-generating component along with energization bus bars, and the heat-transfer portions that are provided in the cooling members, and are in heat-conductive contact with a heat-dissipating body.

Circuit structure

Provided is an electronic module including a housing case for housing a relay, a heat transfer sheet placed on an inner surface of a bottom plate of the housing case, a terminal provided on one surface of the relay opposing a bottom plate, and a crank portion in which a first flat plate portion electrically connected to the terminal and a second flat plate portion that is in contact with the heat transfer sheet are coupled in a crank shape.

Electronic module

Provided is an electronic module including a housing case for housing a relay, a heat transfer sheet placed on one wall portion of the housing case, a bus bar that is connected to the relay and is partially in contact with the heat transfer sheet, and a pressing portion that presses the bus bar against the heat transfer sheet.

Provided is an electrical junction box capable of housing an electric component while absorbing the tolerance of the electric component. The electrical junction box is an electrical junction box that is to be mounted in a vehicle, including: a casing that forms an outer shell; and a fixation member that fixes, to the casing, an electric component that is to be electrically connected to a vehicle-mounted load or an electricity storage device mounted in the vehicle, wherein a slit for absorbing a tolerance associated with external dimensions of the electric component is provided in the fixation member.

An electrical junction box includes a circuit board and a case. The case holds the circuit board therein. The case includes case components bonded to each other such that the case components are liquid-tight to each other. One of the case components includes a connector portion that is liquid-tight to another portion of the one of the case components. The connector portion includes a hood portion to which a mating connector is to be connected. The hood portion includes a ventilation hole that communicates with internal space of the case.
