Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to a terminal corrosion-resistant washer that prevents corrosion of the terminal of an automobile battery.

[Conventional technology]

A pair of terminals 2 on an anode side and a cathode side as shown in FIGS. 7 and 8 are provided on the top surface of a battery case 1 of a battery mounted on an automobile. This terminal 2 is composed of a terminal post 3 and a terminal clamp 4. The terminal post 3 is installed on the upper plate 1a of the battery case 1, and the terminal clamp 4 is attached to the terminal post 3 with a tightening bolt 7. It is detachably attached, and a power cable 5 is connected to it.

By the way, when a car equipped with a battery as described above is running, the battery causes the liquid surface of the electrolyte W in the battery container 1 to wave due to the vibration of the vehicle body, and the lower surface of the upper plate 1a of the battery container 1 is always Therefore, the electrolyte W leaks from the lower part of the terminal post 3 to the upper surface of the upper plate 1a through the gap between the upper plate 1a and the terminal post 3. There is a problem in that the terminal 2 is corroded by the electrolyte W.

Conventionally, as a means for preventing corrosion of the terminal 2, a corrosion-resistant washer 6 as shown in FIG. 6 was provided on the terminal 2.

This anti-corrosion washer 6 is made of porous felt or the like in the shape of a hollow disc and impregnated with anti-corrosion oil.The anti-corrosion washer 6 is fitted onto the terminal post 3 and connected to the top plate 1a of the battery case 1 and the terminal clamp. It is designed to be used between 4 and 4.

[The problem that the idea aims to solve]

However, the above-mentioned conventional corrosion-resistant washer 6
So, when installing or replacing this corrosion-resistant washers 6,
After loosening the tightening bolt 7 of the terminal clamp 4 and removing the terminal clamp 4 from the terminal post 3, attach the corrosion-resistant washer 6 to the terminal post 3.
Therefore, the work of attaching and detaching the corrosion-resistant washer 6 was complicated.

Therefore, in order to solve the above-mentioned problems, the present invention aims to connect the terminal clamp 4 to the terminal post 3.
To provide a terminal corrosion-resistant washer for a battery that can be easily fitted and attached to a terminal post 3 without being removed from the terminal post 3.

[Means to solve the problem]

Next, means for achieving the above object will be explained with reference to FIGS. 1 to 3, which correspond to embodiments.

The corrosion-resistant washer 10 for a terminal such as a battery of this invention is a corrosion-resistant washer 10 for a terminal that is externally attached to a terminal post 3 of a battery, etc., and is made of a disk-shaped cloth material impregnated with anti-corrosion oil and has a hole 13 in the center. a corrosion-resistant member 11 having a notch 14 extending from the hole 13 toward the outer periphery; The holding member 12 has an opening 19 at a position corresponding to the opening 14;

[Effect]

The holding member 12 has its opening 19 connected to the corrosion-resistant member 1.
1, and hold the outer peripheral edge of the corrosion-resistant member 11. A corrosion-resistant washer 10 constituted by the holding member 12 and the corrosion-resistant member 11
is connected to the terminal post 3 by the opening 19.
The holding member 1 is attached and detached from the side, and in the attached state, the holding member 1
Due to the elastic restoring property of 2, the terminal post 3 is fitted onto the terminal post 3 without being deformed.

This prevents the terminal 2 from being corroded by the electrolyte W in the battery case 1.

〔Example〕

Figure 1 is a perspective view showing an embodiment of the corrosion-resistant washer for terminals such as batteries according to the present invention, Figure 2 is an exploded perspective view of the corrosion-resistant washer for terminals in Figure 1, and Figure 3 is for terminals according to the same embodiment. FIG. 3 is a perspective view showing a state in which a corrosion-resistant washer is attached to a terminal.

This corrosion-resistant washer 10 for a terminal is comprised of a corrosion-resistant member 11 and a holding member 12 that holds the same.

First, the corrosion-resistant member 11 is formed of a porous and permeable disk-shaped cloth material such as felt, and has a hole 13 in the center, and a part of the periphery of the hole. A notch 14 is formed along the periphery, that is, at one location on the radius. Also,
A plurality of notches 15 are provided radially from the central hole 13 toward the outer circumference. Further, this corrosion-resistant member 11 is provided with a plurality of positioning holes 16 so as to be held in a fixed position by a holding member 12, which will be described later.

Next, the holding member 12 is made of elastic synthetic resin such as plastic and is formed into a substantially C-shape in which a portion is opened and an opening 19 is formed.
This holding member 12 is composed of a lid part 17 and a container part 18, and a hinge part 20 is provided at the outer end opposite to the opening 19 side, so that each lid part 17 and the container part 18 are connected to each other. Molded in one piece. In other words, the lid part 17 and the vessel part 18 are connected by the hinge part 20, and by using the hinge part 20 as a fulcrum to close the lid part 17 and the container part 18, the above-mentioned corrosion-resistant member 1
It is designed to hold 1.

The lid portion 17 is formed into a plate shape, while the container portion 18
A side wall 21 is formed on the outer periphery of the member, and is designed to cover and hold the outer periphery of the above-mentioned corrosion-resistant member 11 when in use (closed state). Further, the lid portion 17 is provided with a plurality of engagement protrusions 22, and the container portion 1
8 is provided with fitting holes 23 at positions corresponding to these engaging protrusions 22, into which the holes 16 provided in the above-mentioned corrosion-resistant member 11 are fitted, and at the same time. The holding member 12 is coupled to maintain the closed state.

Therefore, in the corrosion-resistant washer 10 for a terminal configured in this way, the corrosion-resistant member 11 impregnated with a conductive corrosion-resistant oil is aligned with the notch 14 of the corrosion-resistant member 11 and the opening 19 of the holding member 12, and the holding member 12
hold it. As shown in FIGS. 3 and 4, when attaching the terminal 2 to the terminal 2, the terminal clamp 4 is not removed from the terminal post 3, but is slightly lifted from the upper plate 1a of the battery case 1, and the corrosion-proof If the opening of the washer 10 is inserted from the side of the terminal post 3, the corrosion-resistant washer 10
is installed. At this time, the opening is smaller than the outer diameter of the terminal post 3, but since it is a resilient member, it can be installed without support, and after installation, the restoring force of the holding member 12 It does not become deformed when attached, and can also be prevented from falling off from the terminal 2. Furthermore, as shown in FIG. 5, even if the outer diameter of the terminal post 3 is large or deformed, the notch 15 is provided in the corrosion-resistant member 11, so that the corrosion-resistant member 11 deforms and can be easily attached. It is possible. In addition, corrosion-resistant member 1
Since the holding member 1 and the holding member 12 are made of different materials, the wearer can be attached without touching the corrosion-resistant member 11 impregnated with anti-corrosion oil and without getting his hands dirty. Furthermore, the corrosion-resistant washer for terminals of the present invention has the effect that installation can be completed in a few seconds, whereas conventionally it took several minutes.

[Effect of idea]

As explained above, the corrosion-resistant washer for terminals such as batteries according to the present invention has an opening so that it can be attached or replaced from the side to the terminal post without removing the terminal clamp, and can be attached and detached. This has the effect of making work easier.

Further, by providing the elastic holding member, this corrosion-resistant washer for a terminal has the effect of not easily falling off.
