Abstract: 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 (1) to a body (12) for an electric junction box, comprises a hole (9) disposed in the bus bar (1), and having a burr (31) created during the hole punching process; and a projection (21) formed in the body (12), and suited for being press-fit into the hole (9), wherein the projection (21) extends beyond the burr after being press-fit into the hole (9). In this configuration, the hole (9) may serve as a basis for position determination of each terminal portion (3, 4) of the bus bar (1), and the projection (21) may serve as a basis for position determination of each terminal-accommodating portion (25) of the body (12).

Abstract: 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.
