Abstract

Provided is a round terminal fixation structure which can easily install a round terminal at a fixation position and prevent assembling failure. The round terminal fixation structure fixes the round terminal connected to an end of an electric wire to a bus bar in an overlapping fashion by a bolt. The round terminal includes a bolt insertion portion having a first through-hole for passing the bolt and a core wire crimp portion crimping a core wire of the electric wire. The bus bar includes a flat plate portion having a second through-hole for passing the bolt and a standing piece extending perpendicularly from the flat plate portion and configured to abut on the core wire crimp portion when bolting the round terminal to prevent rotation of the round terminal. A distal end of the standing piece is slanted towards the flat plate portion with distance from the second through-hole.

First claim

The invention claimed is:

1. A round terminal fixation structure comprising:
a round terminal connected to an end of an electric wire; and
a bus bar, the round terminal being configured to be fixed to the bus bar in an overlapping fashion by a bolt,
wherein the round terminal includes a bolt insertion portion provided with a first through-hole through which the bolt is passed, and a core wire crimp portion crimping a core wire of the electric wire,
wherein the bus bar includes a flat plate portion provided with a second through-hole through which the bolt is passed, and a single standing piece extending perpendicularly from the flat plate portion and configured to abut on the core wire crimp portion of the round terminal when bolting the round terminal to prevent a rotation of the round terminal,
wherein the single standing piece is formed into a quadrangular shape defined by four sides, said four sides including a first side and a second side opposite to the first side, the first side being adjacent to and parallel to the flat plate portion, and
wherein among the four sides defining said quadrangular shape of said single standing piece, the second side is entirely slanted towards the flat plate portion with distance from the second through-hole.
