CONSTITUTION:A curved flexible part 1 is provided between terminal main parts A, which are formed by laminating metal thin band pieces A1. The metal band pieces are closely stuck to each other in one body and connection parts 2 in which connection holes 5 matching electrode posts of a battery are formed on both side of the terminal main parts A.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery connecting terminal used when batteries are connected in series in an electric vehicle.

[0002]

2. Description of the Related Art In FIG. 10, a and a are two batteries fixed on an automobile, and electrode posts b and a
A plate-shaped battery connecting terminal c is fixed between b by engaging its connecting hole with the electrode posts b, b and tightening with nuts d, d.

However, in this structure, the plate-shaped battery connecting terminal c cannot cope with the positional deviation when the battery is mounted, so that the mounting workability is poor and the vibration cannot be absorbed, so that the electrode post cannot be protected. Therefore, FIG.
As described above, a metal flat knit e is used as the main body of the terminal, and metal plates f for screwing are crimped at both ends to form connection holes g (Japanese Utility Model Publication No. 51-15654). .

In this structure, since the flat knit e can expand and contract, it overcomes the above-mentioned drawbacks of the plate-shaped battery connecting terminal c, but the metal plates f for screwing at both ends and the flat knit e are used. However, there are drawbacks such as difficulty in bonding, poor moldability due to press working, and low degree of freedom with respect to current capacity.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and provides a battery connecting terminal having elasticity and excellent moldability.

[0006]

In order to achieve the above object, in the present invention, a bent expansion / contraction allowing portion is provided in the middle of a terminal main body portion in which thin metal strips are laminated, and both end portions of the terminal main body portion are provided. In the above, a configuration is adopted in which the thin metal strips are brought into close contact with each other to be integrated with each other, and a connection portion having a connection hole for the electrode post of the battery is provided.

[0007]

Function: Vibration is absorbed in the bent expansion / contraction allowing portion.

[0008]

1 and 2 show a battery connecting terminal according to the present invention, in which the terminal main body A is formed by laminating about 10 to 15 thin strips _{1 of a} metal of good conductivity made of hard copper or the like having a thickness of 0.1 mm or less. And a mountain-shaped expansion-contraction allowing portion 1 that is bent so as to have a spring function in the middle portion. The connection portions 2 are provided at both ends of the terminal main body portion A. In the connecting portion 2, the reinforcing metal plates 2a, 2 are provided on the front and back of the thin metal strip A ₁ group.
By stacking a and pressing the screw 4 into the perforation 3, the metal thin strips A ₁ and the reinforcing metal plates 2a, 2a are kept in close contact with each other (see FIG. 3). Connection part 2 at both ends
Is formed with a connection hole 5 for the electrode post of the battery.

In the structure shown in FIG. 4, the metal pipe 6 is caulked to be integrated to form the two-end connecting portion 2 '. In the structure shown in FIG. 5, the terminal main body portion A and the reinforcing metal plates 2a, 2a are brazed. Alternatively, they are integrally formed by welding to form the both-end connecting portion 2 ″. In the structure shown in FIGS. 6 and 7, the silicon shrink tube 7 is attached to the terminal main body portion A, and then the both-end connecting portion 2 ′ is formed. There is.

FIG. 8 shows an insulating cap B, on both inner surfaces of which locking cylinders 11 and 11 are provided which are fitted into a tightening nut 10 screwed into an electrode post 9 of a battery.

[0011]

As described above, according to the present invention, a bent expansion and contraction allowance portion is provided in the middle of a terminal main body portion in which thin metal strips are laminated, and the thin metal strips are adhered at both ends of the terminal main body portion. Since it is integrated with the battery and the connection part with the connection hole for the electrode post of the battery is provided, the mounting work can be smoothly performed according to the position shift of the battery, and the vibration of the automobile is absorbed. The electrode post can be protected, and a product corresponding to the current capacity can be easily obtained by changing the number of laminated thin metal strips, which is excellent in formability and productivity.
