There is provided an electric junction box () which can reduce the usage of the heat-resistant resin for a connector fitting portion. The electrical junction box () includes a case () including a box-like body () and a box-like body () to be assembled together, a substrate () received in the case (), a connector fitting portion () arranged to engage with a connector and having a terminal () soldered to the substrate () with lead-free solder, a holding portion () holding the terminal (), and a tubular outer wall () surrounding the terminal (). The holding portion () and the outer wall () are formed as separate parts. The outer wall () is divided into two segments formed integrally with the box-like bodies (), respectively. The holding portion () is made of heat-resistant resin while the outer wall () is made of non-heat-resistant resin.

There is provided a waterproof structure for the electrical junction box includes a stepwise portion in which a punched hole has to be provided for molding a locking projection on a peripheral wall of a main-body case. The waterproof structure prevents intrusion of a droplet from an outside into the main-body case via the punched hole and thereby improves waterproof performance. An extended portionis provided on a left wall portionof the main-body casefor moving the position of the punched hole which should be provided in the stepwise portiontoward the side of the locking projection. A hole-sealing portionis provided at a edge portionof the left wall portionof the cover, the hole-sealing portionis configured to cover the entire opening of the punched holemoved toward the side of the locking projectionin a state where the cover is attached to the main-body case

An electrical connection box includes: a body; a mounting member which is attached to the body; a shaft portion which is provided on the mounting member; and a shaft receiving portion which is provided on the body and receives the shaft portion rotatably. A first rib is formed on one of the shaft portion and the shaft receiving portion. When the mounting member is attached to the body, the first rib abuts against the other of the shaft portion and the shaft receiving portion.

Electrical connection box

The present invention provides an electric connection box capable of carrying out insertion accurately when a plurality of connection terminals provided at a terminal holding member to a plurality of inserting grooves of a terminal inserting member, as a result, capable of preventing deformation of the connection terminal. The electric connection box of the invention includes a terminal holding member having a front surface, a first side surface, and a second side surface and including a plurality of terminals mounted on the front surface so as to be projected from the front surface, an source terminal mounted on the first side surface so as to be projected from the first side surface in a direction in which the terminals align, a guide projected streak mounted on the second side surface along a direction in which the terminals are projected so as to be projected from the second side surface, and a terminal inserting member including a plurality of inserting grooves in which the terminals are inserted, a terminal guide groove in which the source terminal is inserted, and a streak guide groove in which the guide projected streak is inserted.

Electric connection box

The present invention provides an electric connection box capable of reducing cost and capable of constituting small-sized formation by devising a structure of engaging a cover. The electric connection box including an electronic device and connected to a wire harness so as to electrically connect the electronic device and the wire harness includes a synthetic resin member including a mold stripping hole used for molding the synthetic resin member, and a cover including a engaging portion engaged with the hole.

An electrical connection box includes a body, a mounting member attached to the body, a lock arm which is provided at one of the body and the mounting member, and a lock receiving portion which is provided at the other of the body and the mounting member. The lock arm includes an arm portion and a first engaging portion. The lock receiving portion includes a receiving portion which has an inserting portion and a second engaging portion. The receiving portion includes a projection which projects from the surface of the receiving portion farther than the second engaging portion from the inserting portion so as to abut on the arm portion to locate the lock arm in a predetermined position. When the first engaging portion engages with the second engaging portion, a clearance is formed between the receiving portion and the arm portion.

An electrical connection box includes a body which includes a mounting surface and a mounting member, including a shaft portion, attached to the body. The body includes a bearing portion which receives the shaft portion rotatably. The bearing portion has a receiving portion which receives the shaft portion, a limiting portion provided at a position separate from the mounting surface for a predetermined distance, and an insertion port, having a length of the predetermined distance defined by the mounting surface and the limiting portion, through which the shaft portion is inserted into the receiving portion. The limiting portion limits a movement of the shaft portion in a direction parallel to the mounting surface based on an inclining condition of the mounting member.
