Bus bar mounting assembly

摘要

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). A pair of the holes (9) may be spaced apart from each other in a longitudinal direction of the bus bar (1), and a pair of the projections (21) may be correspondingly formed in the body (12) so as to be press-fit into the holes (9). The projection (21) may have a plurality of press-fit ribs (29) extending outwardly from a peripheral surface thereof, and being approximately triangular in traverse cross-section.

主权项

1. A bus bar and a body for an electric junction box assembly, comprising:
a hole disposed in the bus bar, and having a burr, the bus bar provided with a base plate; and a projection formed in the body, and suited for being press-fit into the hole, wherein the projection extends beyond the burr when being press-fit into the hole, wherein the body and projection are formed of a same insulative material and integral with each other, and the projection extends from a wall of the body, wherein the projection includes a plurality of press-fit ribs extending outwardly from a peripheral surface thereof, each of the press fit ribs individually having an approximate triangular cross-section which is in parallel with the base plate of the bus bar, the triangular cross-section having one side facing the press-fit rib and two sides not facing the press-fit rib, and wherein each of the press-fit ribs is press fit into the hole such that one corner of the triangular cross-section not facing the projection and two sides of the triangular cross-section not facing the projection are subjected to compression deformation inside the hole, thereby coming in contact with an interior surface of the hole, wherein the bus bar is mounted to the body of the electric junction box via an engagement therebetween and wherein the engagement only depends on the compression deformation.
