DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a battery terminal.

[0002]

2. Description of the Related Art For example, as shown in FIGS. 3 and 4, a terminal of a vehicle-mounted battery is provided with a power supply screw shaft b projecting from a battery main body a, and a conductive terminal main body is connected to the screw shaft b. c, and the plug e provided on the power cord d is sandwiched and gripped on the outer periphery of the terminal body c to conduct electricity.

[0003]

However, in the battery terminal having the above structure, the terminal body c is rotated integrally with the plug e by unnecessarily moving the plug e via the power cord d. There is a problem that the screwing state with the screw shaft b is loosened and conductivity is easily damaged.

There is another problem that the plug e contacts the metal frame for fixing the battery body a in the vehicle, and the current is easily short-circuited.

In particular, since the inner diameter of the plug e differs depending on the domestic car, the outer car, or the type of car, when the outer diameter terminal body c is changed with respect to the power supply screw shaft b, the outer diameter of the terminal body c is changed. If the screw shaft b is not properly screwed, the above-mentioned problem is more likely to occur.

[0006]

SUMMARY OF THE INVENTION A battery terminal according to the present invention is intended to solve the above-mentioned problem, and a conductive cylindrical terminal body having a screw hole formed in the center at the center thereof is projected from the battery body. Screwing the set screw into the screw hole of the terminal body, and screwing the set screw into the screw hole of the terminal body so that the tip of the set screw is crimped to the tip of the feed screw shaft in the screw hole. It is characterized by.

Further, according to the present invention, when the terminal body is screwed into the power supply screw shaft, an insulating pedestal is interposed between the terminal body and the battery body, and the mounting height of the terminal body is adjusted by the pedestal. It is characterized in that it is obtained.

[0008]

The terminal body can be securely fixed to the power supply screw shaft by tightening the set screw. Moreover, since the plug can be fixed to a desired height by interposing the pedestal, the plug can be set so as not to contact the frame or the like according to the situation, and the possibility of current short-circuit can be avoided.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. In the figure, reference numeral 1 denotes a power supply screw shaft protruding from the battery body 2. Reference numeral 3 denotes an annular pedestal formed of an insulating material such as polyethylene. The pedestal 3 has a notch 4 formed around its outer periphery to prevent rotation.

Reference numeral 5 denotes a cylindrical terminal body made of copper, and a screw hole 6 is formed at the center of the terminal body 5 in a penetrating manner. The outer periphery of the terminal body 5 has a slightly tapered shape and, more precisely, a truncated cone shape. Reference numeral 7 denotes a set screw which can be screwed into the screw hole 6. One end of the set screw 7 has a hexagonal hole 8 for wrench engagement.
Are formed.

In this battery terminal, after the base 3 is passed through the power supply screw shaft 1, the terminal body 5 is screwed into the power supply screw shaft 1, and the base 3 is interposed between the battery body 2 and the terminal body 5. Let it. Then, the set screw 7 is screwed into the screw hole 6 from the other side, and the set screw 7 is tightened with a hexagon wrench so that the tip of the set screw 7 is screwed into the screw hole 6 as shown in FIG. It is crimped to the tip of the shaft 1.

When the set screw 7 is screwed in this way, and the set screw 7 and the power supply screw shaft 1 are hit against each other in the screw hole 6, the reaction between the screw hole 6 and the power supply screw shaft 1 causes the screwed state. The terminal body 5 can be secured to the power supply screw shaft 1 without being loosened.

Reference numeral 10 denotes a plug of the power cord 9. The plug 10 has the power supply screw shaft 1 with the base 3 interposed therebetween.
Can be attached to the outer periphery of the terminal body 5 at a distance from the surface of the terminal body 5. Therefore, by interposing the pedestal 3 having an appropriate thickness as needed, the plug 10 can be set while avoiding the mounting frame and the like, and the risk of current short-circuit can be eliminated.

Further, if the terminal body 5 having an arbitrary outer diameter can be screwed in and the set screw 7 is screwed, the terminal body 5 can be screwed even when an external force is applied to the terminal body 5 via the power cord 9 and the plug 10. The main body 5 is less likely to be loosened than the power supply screw shaft 1, and sufficient electrical conductivity between the power supply screw shaft 1 and the terminal main body 5 can be ensured.

[0015]

As described above, according to the battery terminal of the present invention, the terminal main body is prevented from being loosened, and the power supply screw shaft and the terminal main body can be reliably made electrically conductive. Further, since the terminal body can be mounted at a desired height by interposing the pedestal, the position of the plug of the power cord can be avoided from the mounting state where there is a possibility of current short-circuit if necessary. Therefore, there is a beneficial effect that power can be always supplied without trouble.
