[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a battery terminal connected to a battery mounted on a vehicle, and a method of manufacturing the battery terminal.

[0002]

2. Description of the Related Art A battery terminal connected to an on-vehicle battery is firmly fixed so as to be easily attached to and detached from a battery post. Function is required.

FIGS. 12 to 21 show a conventional battery terminal.

The battery terminal 1 shown in FIGS.
Is an electric wire connection portion 5 that is crimped to a terminal portion of the electric wire 3,
A first fastening portion 7, a loop-shaped battery connection portion 11 mounted on the outer periphery of the battery post 9, a second fastening portion 13, and a rib 15 are provided.

The battery terminal 1 is connected to a battery connection 1
1 is attached to the battery post 9, the first fastening portion 7 and the second fastening portion 13 are bolted to the washer 18 and the washer 18.
And the nut 19, the battery connection portion 11 is firmly fixed to the battery post 9 to prevent falling off.

The outer periphery of the battery post 9 generally has a shape shown in FIG.
As shown in FIG. Therefore, there is a tendency that the bolt 17 and the nut 19 are strongly tightened to prevent the battery terminal 1 from falling off, and the battery terminal 1 may be deformed or damaged by excessive tightening.

Therefore, as shown in FIG.
3 is provided with a rib 15, and when the bolt 17 and the nut 19 are tightened, as shown by an arrow 21 in FIG.
5 is configured to contact the first tightening portion 7 and serve as a stopper to prevent excessive tightening. FIGS. 15 and 16 show a deformed state of the rib 15 when the bolt 17 and the nut 19 are excessively tightened.

The battery terminal 23 shown in FIG. 17 is obtained by adding a separate spring 25 to the battery terminal 1 described above.

After attaching the battery connecting portion 11 to the battery post 9, the battery terminal 23 sandwiches a spring 25 between the first fastening portion 7 and the second fastening portion 13 and fastens with the bolt 17 and the nut 19. As a result, the battery connecting portion 11 is firmly fixed to the battery post 9 to prevent the battery connecting portion 11 from dropping off.
And the nut 19 are prevented from being excessively tightened and the battery terminal 23 is prevented from being damaged.

The battery terminal 27 shown in FIGS.
An electric wire connection portion 29 crimped to a terminal portion of the electric wire;
A fastening portion 31, a loop-shaped battery connection portion 33 attached to the outer periphery of the battery post, and a second fastening portion 35.
And a spring portion 37, which are arranged substantially in one direction. FIG. 18 shows a state where the battery terminal 27 is punched out of a flat plate (deployed state).

As shown in FIG. 18, crimping portions 39, 39 are formed at both ends in the width direction of the electric wire connection portion 29. or,
The spring portion 37 is formed in the width direction of the first tightening portion 31 and is bent at a location indicated by a broken line 41 after punching. When the battery terminal 27 is attached to the battery post and the first fastening portion 31 and the second fastening portion 35 are fastened with bolts and nuts, the spring portion 37 is attached to the second fastening portion 35 as shown in FIGS. The contact and the repulsive force prevent the battery terminal 27 from being damaged due to excessive tightening.

[0012]

However, in the battery terminal 1 shown in FIGS.
When the ribs 15 are tightly tightened, the ribs 15 are deformed as shown by arrows 43 in FIG. 15, and when further tightened, the ribs 15 are crushed as shown by arrows 45 in FIG. 16 and do not serve as stoppers. The function of preventing the battery terminal 1 from being damaged by tightening is insufficient.

In the battery terminal 23 shown in FIG. 17, the number of components is increased by using the separate spring 25,
The assembly work process, parts costs and man-hours increase, and the cost rises.

Further, the battery terminal 2 shown in FIGS.
In FIG. 7, since the width W1 of the spring portion 37 is wider than the width W2 of the caulking portions 39, 39 as shown in FIG. 18, waste is likely to occur at the time of punching, the yield of the flat plate is poor, and the cost increases accordingly.

The present invention has been made in consideration of the above circumstances, and has as its object to provide a battery terminal that can prevent deformation and breakage due to excessive tightening of a screw and has a good yield of material removal, and a method of manufacturing the battery terminal.
