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.

Electric junction box

An electric junction boxincludes: a box main body; and a tubular guide portionprojecting from the box main bodyand guiding a plurality of electric wiresto an outside of the box main body. While the electric wiresare passed through the guide portion, a fixing memberis continuously wound from the guide portionto the electric wires. The guide portionis provided with an expanded portiongradually expanded toward an outside of the guide portionas the guide portionis extended from the box main bodyto an end portion away from the box main body

The waterproof structure of an electrical junction box herein prevents water from entering into the electrical junction box. The electrical junction box includes a main body having a groove formed on an outer wall thereof and a tubular wire cover composed of front and rear split covers. Electric wires are passed downward through the wire cover and fixed to a lower portion of the wire cover using a tape. The wire cover is slidably engaged with the groove of the junction box main body. The waterproof structure includes a step portion as a water stop formed on a rear wall of the wire cover. The rear wall is arranged in contact with or adjacent to a back wall of the groove so that the step portion prevents water from entering into the electrical junction box from bottom along the back wall of the groove through the electric wire.

An electrical wire jacketing configuration used in an electrical junction box herein has a body portion in which a recess is formed. The electrical wire jacketing configuration includes a gutter-shaped portion configured to pass an electrical wire therethrough, a slidable engaging portion formed in both end portions of the gutter-shaped portion in the across-the-width-direction, and is slidingly engabeable with a guide portion of the recess, and a projection extending from the gutter-shaped portion toward the recess so as to prevent possible erroneous or wrong attachment of the electrical wire jacketing configuration to the recess. The recess may have a secondary guide portion configured to proceed the projection into the recess such that the projection can engage with the recess. The electrical wire jacketing configuration to which the electrical wire is fixed slidably moves toward the recess in a longitudinal direction of the electrical wire, and thereby mates with the recess.

Electrical wire jacketing configuration

The electric wire fixture device is provided with a bottom wall on which the electric wire is placed, and a side wall upstanding from the bottom wall. The side wall is provided with an aperture passed through by a fixing member for fixing the electric wire. The fixing member fixes the electric wire so that the fixing member passes through the aperture after being wound around the electric wire and that the electric wire is then brought close to the side wall. The side wall is provided with a pair of ribs projecting toward the electric wire from the side wall. The pair of the ribs is disposed spaced along a longitudinal direction of the electric wire, and the pair of ribs is disposed to position the aperture therebetween.
