An electric wire connected to the electronic component is routed between the electronic component and the lid portion. The housing includes a fixing member fixing the electric wire. The fixing member has a face intersecting with an attachment direction of the lid portion and fixes the electric wire to the face.

A resin structure includes a first resin body, having an annular first side wall portion, a second resin body having a second side wall portion, and a third resin body having an annular third side wall portion. The second resin body is assembled to the first resin body, such that an upper edge of the second side wall portion and at least a portion of an annular lower edge of the first side wall portion in a circumferential direction are aligned. The third resin body is assembled to the second resin body, such that an annular upper edge of the third side wall portion and at least a lower edge of the second side wall portion are aligned.

An electric junction box includes a fitting component to which an electronic component and an electric wire electrically connected to the electronic component are assembled, and a housing in which the fitting component is fitted and held. The fitting component includes a first peripheral wall forming an outer side face of the fitting component, a first bottom wall covering a lower opening of the first peripheral wall, a first drain hole provided in the first bottom wall, and a cylindrical drain portion protruding downward from an edge portion of the first drain hole in the first bottom wall.

An electric connection box includes a housing, a first lid portion, a groove and a water stop wall. The housing includes an opening. The first lid portion includes a first body wall that closes the opening of the housing, and a first peripheral wall extending from a periphery of the first body wall toward the housing. The groove is provided between the first peripheral wall and a wall portion arranged to be spaced apart from the first peripheral wall. The water stop wall is provided on the first lid portion and configured to cover an opening of two ends of the groove in a longitudinal direction.

An electric connection box includes a fitting component having a peripheral wall, a housing having a fitting holding portion, a first water stop portion provided along a first opening end edge of the peripheral wall, a second water stop portion provided along a second opening end edge of the peripheral wall, and a guide lock. The guide lock guides the fitting component with respect to the fitting holding portion along an extending direction of the first opening end edge, and guides the fitting component by a fitting stroke distance along a fitting direction along the first opening end edge and the second opening end edge such that the fitting component is fitted and held. The fitting stroke distance is shorter than a length of the first water stop portion and the second water stop portion.

A resin structure includes a first resin body having an annular first side wall portion, a second resin body having a second side wall portion, and a third resin body having a bottom wall portion and an annular third side wall portion connected to the bottom wall portion. The second resin body is assembled to the first resin body, such that an upper edge of the second side wall portion and at least a portion of an annular lower edge of the first side wall portion in a circumferential direction are aligned. The third resin body is assembled to the second resin body, such that an annular upper edge of the third side wall portion and at least a lower edge of the second side wall portion are aligned.

A booster cable holding structure includes a clamping connection portion configured to be clamped by a clip portion of a booster cable. The clamping connection portion includes a relief terminal portion protruding in a tabular manner from a base structure made of insulating resin, and a terminal supporting resin portion extending in a tabular manner from the base structure over a surface of the relief terminal portion. The terminal supporting resin portion has a groove into which at least one tooth of the clip portion enters when the clip portion clamps the clamping connection portion, and a movement restricting wall configured to block a movement of the clip portion. The movement restricting wall is provided on a side toward which the clip portion having the tooth entered the groove is moved along the groove by an external force that pulls a cable of the booster cable.

Booster cable holding structure

An electrical junction box includes a rescue terminal, protruding from a top surface of a box body, and a terminal supporting plate, attached to the rescue terminal. The rescue terminal has a space in its proximity to allow a clip of a booster cable to be connected to the rescue terminal with the clip in a horizontal lying posture.

A plurality of relays attached to the box body have top surfaces that constitute the supporting portion. To connect the clip to the rescue terminal, the clip in a horizontal lying posture is brought close to the rescue terminal so as to clamp the rescue terminal and the terminal supporting plate on their sides, with the clip placed on the top surfaces of the relays constituting the supporting portion.

Electrical junction box

There is provided an electrical junction box which can improve rigidity of a case body. An electrical junction box includes a block, a case body and an inner cover which regulates a wiring path of an electric wire attached to the block. The case body is formed into a deep box-like shape having a peripheral wall, a bottom wall and an opening portion, wherein a portion of the case body adjacent to the bottom wall has a tapered shape. Cutout portions are formed at two opposing faces of the peripheral wall. A width of the cutout portion is smaller when the case body is in a natural condition in which the block is not housed in the case body than when the block is housed in the case body. The width of the cutout portion is broadened as the block is inserted into the case body.

The electrical connection box includes a block and a frame which accommodates the block. The block is configured to include a terminal support section which supports a relief terminal section of a bus bar in a state in which the relief terminal section of a bus bar is protruded, and a first cover support section which is provided in the vicinity of the terminal support section.
