An electric junction box includes a housing configured to accommodate an electronic component and a lid configured to be attached to the housing to cover an opening of the housing. The housing includes a housing body configured to accommodate the electronic component, and a partition wall dividing an inner space of the housing body. The partition wall is provided with a jig pin hole extending along a direction in which the lid is attached to the housing, the jig pin hole being configured such that a pin provided on a workbench is to be inserted into the jig pin hole making the housing fixed to the workbench on which another component is to be attached to the housing.

A resin structure includes a first resin body, and a second resin body. The second resin body is fit to an outer surface of the first resin body while being slid to one side in a sliding direction along the outer surface of the first resin body. The first resin body and the second resin body form a water stop structural unit extending in the sliding direction in a state where the second resin body is fit to the first resin body. The water stop structural unit includes a first water stop structure in a first region located at the one side in the sliding direction, and a second water stop structure in a second region located at the other side in the sliding direction with respect to the first region.

Resin structure

A resin structure includes a first resin body, and a second resin body. The second resin body is fit to an outer surface of the first resin body while being slid to one side in a sliding direction along the outer surface of the first resin body. The second resin body includes a pair of end edge portions. The pair of end edge portions extend in inclined directions that are inclined with respect to the sliding direction, such that a gap between the pair of end edge portions in a width direction gradually decreases toward one side of the sliding direction, the width direction being orthogonal to the sliding direction and extending along the outer surface. The first resin body includes a pair of facing surfaces spaced apart in the width direction and facing each other.

An electric connection box includes a housing, a first lid portion, a groove, and a protrusion. 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 groove includes an opening in a side of the first body wall in an extending direction of the first peripheral wall. The protrusion is provided on the first lid portion and protruding toward the wall portion. The protrusion covers the opening of the groove.

Electric connection box

An electric junction box includes a housing configured to accommodate an electronic component, and a lid portion attached to the housing so as to cover an opening of the housing. 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.
