Connection structure of bus bar and terminal
By forming a bus bar-swaging part at a terminal, forming a bus bar-crimping part at a bus bar, and providing a crimping posture-retaining part that retains the crimping posture of the bus bar-crimping part when crimping the bus bar-swaging part to the bus bar-crimping part, the present invention provides a connection structure capable of preventing defective crimping caused by the change in the posture of the bus bar-crimping part to thereby enhance the reliability on connection.
1. A connection structure of a bus bar and a terminal of an electric wire end for electrically connecting the bus bar that connects a plurality of apparatuses to each other, with the terminal of the electric wire end, wherein:
the bus bar is formed of a bus bar main body that connects with the plurality of apparatuses with each other, and a bus bar-crimping part which is formed integrally with the bus bar main body, and to which the terminal is connected in a crimped manner;
the terminal is formed of an electric wire connection part to which the electric wire end is electrically connected, and a bus bar-swaging part connected to the bus bar-crimping part;
a crimping posture-retaining part for retaining a crimping posture of the bus bar-crimping part when crimping the bus bar-swaging part to the bus bar-crimping part is provided at the bus bar-crimping part; and
a connection end extending from the bus bar main body and substantially perpendicularly connected to the bus-bar crimping part.
2. The connection structure of a bus bar and a terminal according to claim 1 , wherein:
the bus bar-swaging part is formed of an arc-shaped bottom wall and a pair of side walls that are provided extending from both side parts of the bottom wall in the same direction and that are bent in a mutually approaching direction when swaging the bus bar-swaging part to encompass the bus bar-crimping part; and
the crimping posture-retaining part is a posture-retaining face that is provided at the bus bar-crimping part and that is supported by at least one of the pair of side walls when swaging the bus bar-swaging part to the bus bar-crimping part.
3. The connection structure of a bus bar and a terminal according to claim 2 , wherein:
the posture-retaining face is a flat face or a curved face that makes surface-contact with at least one of the pair of side walls.
4. The connection structure of a bus bar and a terminal according to claim 2 , wherein:
the bus bar-crimping part is formed in a U-letter shape by a base part provided extending from the bus bar main body, a one-side contact piece that is provided extending from the base part to make contact with one side wall of the pair of side walls, an other-side contact piece that makes contact with the other side wall, and a coupling-contact piece that couples the one-side contact piece and the other-side contact piece; and
the posture-retaining face is formed on at least the coupling-contact piece.
5. The connection structure of a bus bar and a terminal according to claim 2 , wherein:
the bus bar-crimping part is formed in a plate shape, and at the side-face part of the bus bar-crimping part in a plate shape, the posture-retaining face that makes surface-contact with the pair of side walls when swaging the bus bar-swaging part to the bus bar-crimping part is formed.
