A resin structure includes a body divided into regions and a lid to cover one of the regions. The body includes a first partition wall extending in a partition direction to partition a pair of regions. The lid covers one of the pair of regions and includes a second partition wall extending along the first partition wall. The first partition wall has a protrusion at an end of the first partition wall, the protrusion protruding toward the second partition wall, and having a first inclined surface inclined in a manner gradually approaching a distal end side in the partition direction toward a distal end of the protrusion away from the first partition wall. The second partition wall has a second inclined surface inclined along the first inclined surface. The lid is to be attached to the body being guided by the second inclined surface facing the first inclined surface.

An electronic circuit breaker for a vehicle, comprising: an input configured to be connected to a DC power supply; an output configured to be connected to a load; said input connected to said output via a semiconductor switch with a linear region of operation, and a saturated region of operation, said semiconductor switch comprises a switch control input; a switch driver configured to control the semiconductor switch and comprising a switch control output; wherein said switch control output is connected to the switch control input via a pre-charge circuit comprising a turn-“ON” branch which is configured to cause the semiconductor switch to operate in the linear region of operation during turn-“ON”; and a turn-“OFF” branch which is configured to cause the switch to turn-“OFF”.

An electrical junction box is configured such that an electric or electronic component is mounted thereon. The electrical junction box includes a case having an accommodation recess, a housing configured such that the electric or electronic component is held therein and configured to be attached in the accommodation recess, and a cable configured to be drawn into the accommodation recess. The housing includes a path restricting wall configured to restrict a wiring direction of the cable.

An electrical junction box includes a case body having a plurality of connector portions, a power supply side circuit board accommodated in the case body and a spare connector mounting portion provided in an upper portion of the case body and configured such that a spare connector is attached to and detached from the spare connector mounting portion. The spare connector includes a fuse configured to electrically connect the power supply side circuit board to a device side terminal connected to an end of an electric wire configured to be electrically connected to an electronic device.

An electrical junction box includes a frame body, a rescue terminal portion formed in a rectangular parallelepiped shape in a plan view and including a longitudinal side face, two lateral side faces connected to the longitudinal side face, and an upper face, a resin cover configured to cover the longitudinal side face, the two lateral side faces and the upper face. The resin cover includes a rotary shaft extending along the longitudinal side face and provided on a side where the longitudinal side face is provided and on a base end portion of the rescue terminal portion opposite to the upper face, the resin cover being configured to rotate with respect to the frame body about the rotary shaft.

An electrical junction box includes a case body having a plurality of connector portions, a power supply side circuit board accommodated in the case body and a general-purpose connector mounting unit provided in the case body and configured such that a plurality of types of connectors are selectively attached to and detached from the general-purpose connector mounting unit. The general-purpose connector mourning unit is configured such that a power supply side terminal of the plurality of types of connectors is electrically connected to a terminal connection portion of the power supply side circuit board.

A junction box includes a housing having a plurality of side wall portions, and a liquid detector including a first terminal portion and a second terminal portion. The junction box is disposed in a housing case housing a power storage module. The first terminal portion and the second terminal portion are directed toward a lower side of one of the side wall portions and drawn out from the inside of the housing to the outside of the housing.

A connection structure of an electrical junction box includes: a first housing which is fixed to a vehicle and in which a through hole is formed; and a terminal block that is inserted into the through hole, has a conductor, and is supported by the first housing, wherein the conductor includes a first terminal portion placed on one side of the through hole in a penetrating direction in which the through hole penetrates the first housing, and a second terminal portion that protrudes from the first housing toward the other side in the penetrating direction and that is connected to an electric wire.

Provided is an electrical junction box (100) including a housing (30) that houses a substrate (21) to which a fixed fuse (10) is soldered. The housing (30) includes a checking opening (33) for checking whether or not the fixed fuse (10) has been blown out.
