[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal crimping apparatus for connecting a terminal and a conductor used for a wire harness used in an electric circuit.

[0002]

2. Description of the Related Art Conventionally, in a terminal crimping step for connecting a conductor and a terminal, a terminal crimping machine a as shown in FIG.
And a band-shaped terminal carrier c formed by connecting a large number of terminals b in a chain as shown in FIG.
Is fed between the crimping crimper f of the terminal crimping machine a and the anvil g by the feed claw e driven by the terminal supply lever d, and the crimping piece h formed at the conductor connection portion of the terminal b is crimped. The crimping of each terminal b and a conductor (not shown) is continuously performed.

The terminal carrier c is provided with a feed hole i, and the feed claw e of the terminal supply lever d is hung on the feed hole i and is intermittently sent out in the direction of the crimping crimper f so that a predetermined position is obtained. The terminal b connected to the terminal carrier c.

[0004] However, in such a terminal crimping machine a, since the terminal c is positioned by the feed claw hung on the feed hole i of the terminal carrier c, the terminal is not sufficiently held and the crimping position becomes insufficient. It is inaccurate, and has a problem that a crimping failure easily occurs. In addition, although it is good to crimp a large number of terminals b connected in a chain at regular intervals, it is not suitable for crimping different types of terminals.

On the other hand, as shown in an explanatory view of the mechanism in FIG. 10, caulking plates A, B, C,
A turntable type terminal crimping machine in which D, E, and F are arranged has been proposed. This turntable type terminal crimping machine is provided with terminal supply units A ', B', C ', D', E ', F' for supplying six types of terminal carriers at a position slightly away from the turntable j. In addition, a caulking portion k is provided at a predetermined position on the turntable j, and a conductor supply portion m for supplying the conductor n by a conveyor belt is provided at the caulking portion k.

When crimping, for example, to the terminal of the terminal supply section A 'by this terminal crimping machine, the turntable j is rotated so that the crimping machine A coincides with the moving line L, and the crimping is performed. The board A is detached from the turntable j and is moved along the movement line L to a position S in front of the terminal carrier A '. Then, when one terminal is supplied from the terminal supply unit A 'to the caulking board A, the caulking board A is again moved on the moving line L again while holding the terminal, and is returned to the original position on the rotary table 21. return. Next, the turntable j is rotated to position the caulking board A at the caulking section k, and the conductor n supplied from the conductor supply section m and the caulking board A
Is crimped to the terminal held in the terminal.

When crimping of the terminal carrier C 'is completed after crimping of the terminal of the terminal carrier A', the caulking board C is moved to the front of the terminal carrier C 'along the moving line L, and the terminal carrier C' is crimped. By the same operation as in the case of A ', the terminal of the terminal carrier C' and the conductor n supplied from the conductor supply section m are crimped.

[0008] Therefore, in the process of moving the predetermined caulking board until the terminal is crimped, the turntable j is rotated to make the caulking board coincide with the moving line L, and then the caulking board is moved from the turntable j. After the terminal is received and the terminal is received along the moving line L and returned to the original position of the turntable j again, the turntable j is rotated again to rotate the kneading position k. , It takes a long time until the crimping of the desired terminal is completed, and there is a problem that the productivity is reduced.

[0009]
