Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an anticorrosion washer for a battery terminal that prevents corrosion of the terminal of an automobile battery.

(Prior Art) First, an overview of this type of conventional anti-corrosion washer will be described with reference to FIGS. 6 to 8.

A pair of terminals 2 on the positive side and negative side are installed on the top surface of the battery case 1 installed in the car.
The male terminal post 3 constituting each terminal is planted on the top plate of the battery case 1, and the female terminal clamp 4 is fixed to the tip of the power cable 5. There is.

Therefore, the terminal clamp 4 has a through hole for the tightening bolt 5 in the fork portion 4a on one side, and when installing the terminal clamp 4 on the terminal post 3, the slotted hole of the terminal clamp 4 has a circular cross section. After pushing in the post 3, tighten the tightening bolt 5 inserted into the through hole with the nut 6.
The slot is thereby crimped and fixed to the outer peripheral surface of the terminal post 3.

By the way, while the car is running, the liquid level of the electrolyte W in the battery container 1 rises due to the vibration of the car body.
The area around the bottom of terminal post 3 is always filled with electrolyte W.
Therefore, the terminal 2 is easily corroded by the electrolytic solution that rises between the edges of the battery case 1 and leaks onto the top surface of the battery case 1.

As a means for preventing this, an anti-corrosion washer 7 is provided, that is, the anti-corrosion washer 7 is fitted onto the terminal post 3 and interposed between the battery case 1 and the terminal clamp 4.

This conventional anti-corrosion washer 7 has a porous hollow disk impregnated with anti-corrosion oil, and this oil acts to prevent the electrolyte from rising.

(Problems to be solved by the invention) By the way, according to the conventional anti-corrosion washer 7 described above, when attaching or removing the anti-corrosion washer 7 for attaching or replacing the anti-corrosion washer, it is necessary to loosen the fixing nut 6 of the terminal clamp 4. After that, remove the terminal clamp 4 from the terminal post 3, and then attach the anti-corrosion washer 7 to the terminal post 3.
The anti-corrosion washer 7 had to be inserted and removed from above, and therefore, the operation of attaching and detaching the anti-corrosion washer 7 was troublesome.

Therefore, an object of the present invention is to provide a corrosion-proof washer for a battery that can be fitted onto the terminal post 3 without removing the terminal clamp 4 from the terminal post 3.

(Means for solving the problem) In order to achieve the purpose, in this invention,
As shown in the embodiments shown in FIGS. 1 to 5, the terminal clamp 4 is detachably provided at the tip of the terminal post 3 of the battery and is externally fitted to the base of the terminal post 3 between the battery case 1. Anti-corrosion washer 8 for the terminal of the battery to be installed,
11, it is in the shape of a disc made of cloth material impregnated with anti-corrosion oil, and has hollow parts 9b and 12b formed in the center thereof into which the terminal post 3 is inserted, and one place on the circumference thereof. There is a hollow part 9 on the radius of
Plate bodies 9, 12 in which splits 9a, 12a communicating with b, 12b are formed, and opposing ends are provided on both sides of the splits 9a, 12a on the plate surfaces of the plates 9, 12. It is characterized in that it has a split ring 10 that is provided along the plate and gives elastic restorability to the plates 9 and 12 in the direction of closing the splits 9a and 12a.

(Embodiments) Hereinafter, the structure of the present invention will be specifically described based on two embodiments shown in FIGS. 1 to 5.

Embodiment 1 (See FIGS. 1 and 2) The anticorrosion washer 8 of this embodiment is formed into a disk shape using a porous cloth material such as woven fabric, knitted fabric, or nonwoven fabric, and has a terminal in its center. The main body is a plate 9 in which a hollow portion 9b into which a post is inserted is formed, and the plate 9
A crack 9a communicating with the hollow portion 9b is cut on the radius of one location on the circumference of the plate body 9, and in the plate wall on the circumferential line near the inner circumference of the plate body 9, there are cut holes on both sides of the split 9a. A split ring 10 made of elastic wire split and formed is embedded.

However, the inside of the plate end 9 of the lever is impregnated with a conductive oil for corrosion prevention.

The second embodiment (see FIGS. 3 to 5) The anticorrosion washer 11 of the embodiment includes a folded plate body 12 formed into a hollow disk having a chrysanthemum-shaped cutout using a porous cloth material similar to that described above. is the main body, and the folded overlapping surfaces are adhered with adhesive or the like.

However, in one place on the circumference of the lever plate 12,
A split 12a communicating with a hollow portion 12b formed in the center of the plate 12 is cut, and a folded bag portion near the inner periphery of the plate 12 has split molding formed on both sides of the split 12a. A similar split ring 10 is embedded.

Furthermore, the inside of this plate 12 is impregnated with conductive oil for corrosion prevention.

Note that the chrysanthemum-shaped notch in the shape of this plate 12 is
This is a notch created during manufacturing and is not a functionally necessary shape.

In addition, in the configurations of the above embodiments, the split ring 10 may be made of a wire material such as rubber or elastic resin instead of the elastic wire.

The anti-corrosion washers 8, 11 of each of the embodiments configured as described above are attached to the battery in the same way as the conventional anti-corrosion wire 7, and provide anti-corrosion effects to the terminal 2.
In this case, there is no need to remove the terminal clamp 4 from the terminal post 3 when attaching and detaching the anti-corrosion washers 8 and 11. In other words, it is not necessary to remove the terminal clamp 4 from the terminal post 3 after loosening the nut 6 of the terminal clamp 4 slightly. 1, and then insert the hollow parts 9b, 12b into the terminal post 3 from the side with the slots 9a, 12a of the washers 8, 11 open. As a result, the washers 8 and 11 return to their free disk shapes, so they can be used in the same manner as the conventional anti-corrosion washers 7.

(Function) (Effect of the invention) As described above, according to the anti-corrosion washer for batteries according to the present invention, the hollow disc-shaped plate forming the main body of the washer communicates with the hollow part provided at the center of the washer. In addition to cutting the split, a split ring was provided on the plate to give it elastic restoring force, making it possible to open the split and wrap or remove the terminal post from the side. This has the effect of facilitating attachment/detachment operations.
