A structure for screw-tightening and connecting a terminal to an electrical junction box is provided. The terminal mounting structure in the electrical junction box ensures mounting operation with an insertion direction of the terminal obliquely oriented, and prevents heating of the terminal due to power supply. The terminal is secured and connected to a busbar of the junction box by a bolt, with a head and a shaft of the bolt inserted into a vertical opening and a horizontal notched hole of the terminal, respectively. A pair of opposed guiding walls are provided on a junction box body at both sides of the bolt. The guiding wall includes an entrance's side sloping surface obliquely extending from top to bottom, and a straight horizontal surface continuing to the sloping surface. The terminal includes a pair of outward projecting pieces at an upper portion to be slid on the sloping surface and the horizontal surface. A heat release portion extends integrally at an upper portion of a vertical plate portion of the terminal having the vertical opening. Linear indentations are provided on front and back surfaces of the heat release portion to be exposed outside.

A junction block includes attaching brackets projected from the upper wall and lower wall of a block body. The block body is attached to a body panel through the attaching brackets. The attaching bracket to be pulled is provided with a recessand/or a holefor inducing rupture. When a wire harness derived from the block body is pulled in a vehicle width direction during recovery of the junction block, the block body is ruptured-separated from the attaching bracket at the recessand/or hole. In such a configuration, the block body can be rupture-separated only during recovery of a junction box body without being ruptured-separated owing to vibration/shock during vehicle running to improve recovery workability and recycling property.

Attachment structure for electric junction box

An electrical junction box has a fitting member for securing the junction box to a vehicle body. The fitting member has a breakdown accelerating portion for enhancing breakdown of the fitting member when the junction box is pulled to remove it from the vehicle body. The breakdown accelerating portion is positioned in a base side of the fitting piece. By a transverse force caused by pulling an associated wiring harness, the breakdown accelerating portion initiates breakdown of a bracket to separate the junction box from the bracket. Another fitting device has a fitting member formed on a junction box for securing the junction box to a vehicle body. The fitting member has a slot for enhancing breakdown of the fitting member when the junction box is pulled to remove the junction box from the vehicle body, and the fitting member has a compensating piece removably inserted into the slot for adjusting the breakdown of the fitting member.

A metal terminal adapted to be fixedly held between a terminal connecting portion and a fastening member provided at the terminal connecting portion, the metal terminal comprising an electrical contact portion which can be slid to be inserted between the fastening member and the terminal connecting portion so as to be connected to the terminal connecting portion; a wire connecting portion which extends from the electrical contact portion, a wire being adapted to be connected to the wire connecting portion; and an upstanding piece portion which is provided so as to extend in an upstanding manner from the electrical contact portion, and is disposed rearwardly of a connection part of the electrical contact portion in a direction of sliding of the electrical contact portion. The connection portion of the electrical contact portion is adapted to be held between the fastening member and the terminal connecting portion.

A conductive bus bar includes a first plate-shaped portion extending in a first direction and a second plate-shaped portion continued from the first portion and extending in a second direction perpendicular to the first direction. The second plate-shaped portion has a first main face which faces the first plate-shaped portion, a second main face opposite to the first main face, and side faces connecting the first main face and the second main face. A press-contact portion is formed in the second plate-shaped portion, to which an electric wire is press-fitted. An insulative mount includes a mount face, on which the first plate-shaped portion is disposed, and a wall member extending in the second direction to support the second main face of the second plate-shaped portion. A pair of rib members are extended from the wall member to support the side faces of the second plate-shaped portion.
