A case is formed with a long accommodation portion for accommodating an FL holder and a J/C adapter. The accommodation portion is provided with first locking portions configured to lock the FL holder. The FL holder is provided with second locking portions configured to be locked to the first locking portions, and a third locking portion configured to lock the J/C adapter. The third locking portion is provided at one end portion of the FL holder in a longitudinal direction. The J/C adapter is provided with a fourth locking portion configured to be locked to the third locking portion. The FL holder and the J/C adapter are arranged side by side in the accommodation portion along the longitudinal direction.

Electric junction box and accommodating method of holding portion

A resin structure includes first and second resin bodies including first and second wall portions and first and second engagement portions, respectively. One of the first engagement portions engages with one of the second engagement portions and form a first engaging part. Another one of the first engagement portions engages with another one of the second engagement portions and form a second engaging part. The first engaging part is positioned on a further front side than the second engaging part in an attaching direction of the second resin body to the first resin body. When the second resin body is rotated toward the first resin body with the first engaging part as a center of rotation and with the one of the first engagement portions being engaged with the one of the second engagement portions, the first wall portion is prevented from interfering with the second wall portion.

Resin structure

In an electric junction box, both first locking portions and second locking portions are provided in one accommodation portion. The first locking portions are capable of locking an FL holder when the FL holder is inserted from an upper opening toward a lower opening. The second locking portions are capable of locking an FL holder when the FL holder is inserted from the lower opening toward the upper opening. Accordingly, the FL holders can be inserted into the same accommodation portion from the upper opening and the lower opening.

Electric junction box and assembling method thereof

A resin structure has an insertion portion through which an electric wire runs. The resin structure includes a first resin body and a second resin body to be attached to the first resin body in an attaching direction so as to cover the opening portion. The first resin body includes a first wall portion forming a part of a wall portion perpendicular to the attaching direction, and a first insertion portion provided in the first wall portion and forming a part of the insertion portion. The second resin body includes a second wall portion forming another part of the wall portion, and a second insertion portion provided in the second wall portion and forming another portion of the insertion portion. When the first resin body and the second resin body are attached to each other, the insertion portion is disposed in the wall portion of the resin structure.

Resin structure and wire harness

There is provided an electrical junction box including: a bolt holding portion that includes a stud bolt and a bolt holding portion body configured to hold the stud bolt; a first holding portion that includes a first busbar provided with a first connection terminal and a first holding portion body configured to hold the first busbar and a first electronic component; and a second holding portion that includes a second busbar provided with a second connection terminal and a second holding portion body configured to hold the second busbar and a second electronic component. The bolt holding portion, the first holding portion, and the second holding portion are assembled with a nut in a connection state in that the stud bolt is passed through the first connection terminal and the second connection terminal, and in that the first busbar and the second busbar are overlapped with each other.

Electrical junction box

An electronic component unit applicable to a wire harness includes: a plurality of blocks each including at least one main body portion to each of which an electronic component is attached, the blocks each including block-side joints for joining any two of the blocks to each other, the blocks being joined together via the block-side joints with the main body portions arranged side by side in a first direction with gaps between adjacent ones of the main body portions; and a supporting wall body including a plurality of wall-body side joints for supporting and fixing in a second direction intersecting the first direction, in a cantilever fashion, the blocks joined together via the block-side joints.

Electronic component unit and wire harness

An electrical connection box includes first insertion lock mechanisms and second insertion lock mechanisms. The first insertion lock mechanisms include respective first insertion locking pieces and respective first insertion receivers, and serve as rotation fulcrums of relative rotation of a lower cover and a frame in a state in which the respective first insertion locking pieces are inserted into the respective first insertion receivers and the respective first insertion locking pieces are not locked in the respective first insertion receivers. The second insertion lock mechanisms include second insertion locking pieces and second insertion receivers, guide the second insertion locking pieces with the second insertion receivers in a state in which the first insertion lock mechanisms serve as the rotation fulcrums, and determine the relative positions of the frame and the lower cover.

Electrical connection box and wire harness

An electrical connection box and a wire harness is provided with a casing including: a frame and an upper cover that are assembled to each other and that define a housing space portion; and insertion ports that are formed by opening a boundary edge of the frame or the upper cover to cause a conductive wiring material to be inserted through each of the insertion ports. The frame includes a pair of holding pieces that are provided on both sides of the insertion ports, the pair of holding pieces having flexibility in a clipping direction, and clipping and holding the wiring material. The upper cover includes a supporting projection rib that supports the pair of holding pieces at the side opposite from the wiring material, while the frame and the upper cover are assembled to each other.

An electrical connection box applied to a wire harness includes a housing body and a covering member. The covering member includes a lid portion capable of closing an opening of the housing body, a holding portion formed to protrude from the lid portion, and fits to the opening and holds an exterior material between the holding portion and the housing body, a supporting portion serving as a rotation fulcrum of the lid portion with respect to the housing portion, an extension portion connects the lid portion and the supporting portion such that the holding portion is at a position apart from the supporting portion, and a plurality of engagement portions engaged with the housing body on both sides of the holding portion in a direction in which the extension portion connects the lid portion and the supporting portion.
