By screwing and tightening the nut 5 through the, the diameter of the crimping portion 23 is reduced and the crimping portion 23 is mounted on the battery post 2. However, in the above-mentioned battery terminal 21, as shown in FIG. 4, an electric wire crimping portion 29, which is a crimp connection portion of the electric wire 8, has a length corresponding to the length of the fastening piece 27. Only the distance from the battery post 2, the distance L 2 from the core wire crimping portion of the electric wire 8 to the center of the battery post 2 increases, and the effect of the specific resistance and the like of the material of the battery terminal 21 increases, thereby lowering the conductive performance. There was a problem. [0005] When the battery terminal 21 is mounted on the battery post 2, excessive tightening is likely to occur in order to generally avoid inconvenience such as poor electrical contact due to insufficient tightening. Moreover, the battery terminal 21 and the battery post 2 are usually formed of a soft metal having a low elasticity range such as lead or brass from the viewpoint of required electrical connection characteristics and chemical resistance, and have low load resistance. Therefore, in the conventional battery terminal 21 as shown in FIG. 3, there is a possibility that plastic deformation such as cracks may occur in the tightening pieces 26 and 27 during the tightening operation by the bolt 4 and the nut 5, and When plastic deformation occurs in the fastening piece 27, which is a conductive path interposed between the electric wire crimping portion 29 forming the crimp connection portion and the battery post 2,
As a result, there is a possibility that the conductive performance is further deteriorated. Therefore, an object of the present invention is to solve the above problems,
An object of the present invention is to provide a good battery terminal capable of suppressing a decrease in conductive performance due to the influence of the specific resistance of the material of the battery terminal and the plastic deformation of the fastening piece. SUMMARY OF THE INVENTION The object of the present invention is to provide a crimping portion formed into a substantially C-shape for fitting to a battery post, and extending at both ends of the crimping portion so as to face each other. A pair of tightening pieces for crimping the crimping portion to the battery post by tightening with a bolt and a nut; and an upper end and a lower end edge of the crimping portion for crimping a wire to be connected to the battery post to the crimping portion. And a battery terminal integrally formed by press-forming a metal plate. Hereinafter, an embodiment of a battery terminal according to the present invention will be described in detail with reference to the accompanying drawings.
1 and 2 are an exploded perspective view and a plan view showing a configuration of a battery terminal 1 according to one embodiment of the present invention. The battery terminal 1 is integrally formed by press-molding a metal plate. The battery terminal 1 is opposed to a substantially C-shaped crimping portion 3 which is fitted to the outer periphery of a frusto-conical battery post 2. A pair of tightening pieces 6 and 7 extending from both ends of the crimping section 3, and a bolt 4 and a nut 5 for crimping the crimping section 3 to the battery post 2 by tightening the tightening pieces 6 and 7. A wire crimping portion 9 extending directly from upper and lower edges of the crimping portion 3 and crimping and connecting the wire 8.
And a configuration having: Therefore, the wire 8 is tightened by the wire crimping portion 9.
The battery terminal 1 whose core wire is crimped in advance is
The screw portion 11 of the bolt 4 is inserted into a bolt insertion hole 10 formed through each of the pair of tightening pieces 6 and 7, and the screw 5 protruding from the nut-side tightening piece 7 is inserted through the washer 12 through the washer 12. Are screwed together and tightened, so that the crimping portion 3
Is reduced and attached to the battery post 2.
Then, the electrical connection between the battery post 2 and the electric wire 8 is completed. That is, in the battery terminal 1 of the present embodiment, the core wire of the electric wire 8 crimped and connected to the crimping portion 3 by the wire crimping portion 9 is separated from the battery post 2 only by the thickness of the crimping portion 3. not, from the center of the battery post 2 can be suppressed distance L 1 to the core wire crimping portion of the electric wire 8 to a minimum, the decrease in conductivity performance due to the influence of the specific resistance of the material battery terminal 1 can be prevented . Also, by arranging the wire crimping portion 9 on the outer periphery of the crimping portion 3,
The battery terminal 1 can be reduced in size and weight. When the battery terminal 1 is mounted on the battery post 2, the fastening pieces 6, 7 do not intervene in the conductive path from the battery post 2 to the wire crimping portion 9 serving as the core wire crimping portion of the wire 8. Bolt 4 and nut 5
Even if plastic deformation such as cracks occurs in the tightening pieces 6 and 7 due to the tightening, the plastic deformation does not affect the conductive performance between the battery post 2 and the core crimping portion of the electric wire 8 and is excellent. The conductive performance can be maintained. Therefore, it is possible to prevent the terminal portion from generating heat due to a decrease in the conductive performance. It should be noted that the battery terminal of the present invention is not limited to the configuration of each of the above-described embodiments, but may take various forms based on the spirit of the present invention.

According to the battery terminal of the present invention, the electric wire crimping section for crimping connecting wires to be connected to the crimping portion to the battery post on the crimping portion by press molding
Since the directly extending from the lower edge, spaced a battery terminal when attached to the battery post, the core wire of the wire from only the battery posts by thickness amount of the crimping portion to be crimped connected to the crimping portion by electric wire crimping section without the distance L 1 from the center of the battery post to the core wire crimping portion of the electric wire can be minimized. Therefore, it is possible to prevent a decrease in the conductive performance due to the influence of the specific resistance of the material of the battery terminal. In addition, by arranging the wire crimping portion on the outer peripheral portion of the crimping portion, the size and weight of the battery terminal can be reduced. Further, when the battery terminal is mounted on the battery post, no fastening piece is provided in the middle of the conductive path from the battery post to the wire crimping portion serving as the wire core crimping portion. Even if plastic deformation such as cracks occurs in the fastening piece, the plastic deformation does not affect the conductive performance between the battery post and the core crimping part of the electric wire, and it is possible to maintain excellent conductive performance. it can. Therefore, it is possible to prevent the terminal portion from generating heat due to a decrease in the conductive performance. Therefore, it is possible to provide a good battery terminal capable of suppressing a decrease in conductive performance due to the influence of the specific resistance of the material of the battery terminal and the plastic deformation of the fastening piece.
