Abstract

A connection structure of a bus bar and a cable has: a bus bar that serves as an external terminal; a cable that has a core wire exposed from an insulation sheath at a terminal, the core wire being joined with the bus bar; a protective member that covers at least a joining portion of the bus bar and the core wire of the cable; and a cut portion that is formed in the core wire at the joining portion with the bus bar.

First claim

What is claimed is:

1. A connection structure of a bus bar and a cable comprising:
a bus bar that serves as an external terminal;
a cable that includes a core wire exposed from an insulation sheath at a terminal, the core wire being joined with the bus bar;
a protective member that covers at least a joining portion of the bus bar and the core wire of the cable; and
a cut portion that is formed in the core wire at the joining portion with the bus bar, wherein
the cut portion has a joining surface formed by cutting a joining direction side of the joining portion with the bus bar and a vertical surface formed to be perpendicular to the joining surface,
the connection structure of the bus bar and the cable further comprises a gap formed between the vertical surface and a rear surface of the bus bar facing to the vertical surface, and
the protective member covers the bus bar and the cable from at least a front surface of the bus bar in an axial direction to the joining portion.

2. The connection structure of the bus bar and the cable according to claim 1 , wherein
the cut portion is obtained by cutting the joining portion with the bus bar at the joining direction side of the core wire.

3. The connection structure of the bus bar and the cable according to claim 1 , wherein
the joining surface of the cut portion that is joined with the bus bar is formed to be a flat surface.

4. The connection structure of the bus bar and the cable according to claim 1 , wherein
the bus bar and the core wire of the cable are joined by means of ultrasonic welding; and
the protective member has an insulating property and a cylindrical shape.

5. The connection structure of the bus bar and the cable according to claim 1 , wherein the protective member has a cylindrical shape.

6. The connection structure of the bus bar and the cable according to claim 1 , wherein the protective member is formed in a hard cylindrical form.

7. The connection structure of the bus bar and the cable according to claim 1 , wherein the protective member is configured to function as a connector housing.
