The present invention is intended to provide a novel assembly for properly or accurately mounting the terminal portion of the bus bar on the terminal-accommodating portion of a body for an electric junction box without doing any harm to an electrical conduit(s) which is disposed within the electric junction box. An assembly for mounting a bus bar () to a body () for an electric junction box, comprises a hole () disposed in the bus bar (), and having a burr () created during the hole punching process; and a projection () formed in the body (), and suited for being press-fit into the hole (), wherein the projection () extends beyond the burr after being press-fit into the hole (). In this configuration, the hole () may serve as a basis for position determination of each terminal portion () of the bus bar (), and the projection () may serve as a basis for position determination of each terminal-accommodating portion () of the body (). A pair of the holes () may be spaced apart from each other in a longitudinal direction of the bus bar (), and a pair of the projections () may be correspondingly formed in the body () so as to be press-fit into the holes (). The projection () may have a plurality of press-fit ribs () extending outwardly from a peripheral surface thereof, and being approximately triangular in traverse cross-section.

Bus bar mounting assembly

An electric connection box including a box main body, an integration mounted at the box main body, a pair of connection devices, and a plurality of ribs. The pair of connection devices are structured with one of connection devices provided at the integration and the other of connection devices provided at the box main body. The plurality of ribs are arranged at the box main body, and abuts on the integration and is deformed when the integration is mounted at the box main body so as to prevent rattling of the integration. Second ribs among the plurality of ribs, which are arranged close to the other of connection devices, are formed stiffer than first ribs arranged away from the other of connection devices farther than the first ribs.

Electric connection box

A block body made of insulating synthetic resin having a terminal supporting plate in one piece therewith. A plurality of elongated ribs project on one surface of the terminal supporting plate and a rescue terminal is arranged on the other surface of the terminal supporting plate. A bus bar is mounted in the block body. A clamping portion of a booster cable can grasp both the rescue terminal and the rib at one time. The plurality of ribs are parallel to each other. The dimension of the rib is defined such that the rib is placed under compressive deformation when the rib is clamped by the clamping portion. The block body has a hole through which the rescue terminal is passed such that the rescue terminal extends along and in contact with the other surface of the terminal supporting plate.

Rescue terminal structure

An electrical junction box including a box main body and a wiring block. The box main body includes a cassette block. The wiring block includes a first bus bar, a second bus bar, and a fuse. Each bus bar includes an electric parts connecting part and the power source connecting part. The electric parts connecting part is connected to electric parts attached to the cassette block. The power source connecting part includes a fuse connecting piece and a connecting piece. A terminal fitting connected to a power source is connected to the connecting piece. The fuse connects the fuse connecting pieces of the bus bars.

Electrical junction box

For preventing incomplete lock of a terminal at lock leaves of a connection box main body, and locking the terminal smoothly and securely at the lock leaves, a terminal lock device includes a connection box main body made of insulation resin, having a surrounding wall for receiving a terminal, and a pair of flexible lock leaves in the surrounding wall. A tab of the terminal with an electric wire is structured for inserting a head of a bolt. The tab is locked at the lock leaves. The terminal is connected to a mating circuit by screwing. A cover includes projecting plates, which are respectively inserted into bending spaces for bending the lock leaves when the cover is attached at the connection box main body. A pair of wall ribs is provided adjacent to the lock leaves, and a pair of tab ribs is provided at both ends of the tab.

Terminal lock device for screw lock terminal

An electric junction box, which can be easily assembled even if the electric junction box includes an electric power distributing unit, is provided. The electric junction box includes: a box body; a busbar attached to the box body, electric power from a power supply being supplied to the busbar; an electric power distributing unit attached to the box body, the electric power being supplied to the electric power distributing unit through the busbar; and a connector section connecting the busbar to an electric power inputting section of the electric power distributing unit, the box body being provided with the connector section.
