BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage battery cover which is arranged on the upper part of a storage battery and prevents the terminals and connecting members from being exposed when a plurality of storage batteries are connected and used as an assembled battery.

[0002]

2. Description of the Related Art Conventionally, stationary storage batteries have been often used for standby power sources in factories and buildings, for communications, or for controlling power plants. The stationary storage battery is usually used as an assembled battery by connecting a plurality of batteries, avoiding the exposure of connecting members such as copper connecting rods and terminals used for connecting between batteries and between battery rows, and contacting metal tools. A cover was used to cover the top to prevent short circuits and electric shock. For example,
In the cover for the cathode absorption type stationary lead-acid battery, as shown in FIG.
As shown in Fig. 4, a cylindrical portion 2 for fitting a safety valve that protrudes downward in the central portion of the upper surface wall, and a voltage measurement provided at a position on the upper surface wall just above the positive and negative electrode terminals of the storage battery A small hole 3 for inserting a tester pin, and a notch 5 for penetrating a connecting rod, which is provided on the long side surface of a side wall projecting downward from the entire circumference of the upper surface wall so as to face the positive and negative terminals, respectively. Was equipped with.

[0003]

However, in the case of the conventional storage battery cover, when the stationary storage battery is installed as an assembled battery, the cover may not be used as it is depending on the arrangement and the storage method. For this reason, assuming the installation status of the storage battery, additional processing is performed in advance at the manufacturing site of the storage battery cover or by requesting an external processor to perform additional processing. It was necessary to add a notch for the connecting rod and a hole for the upward lead wire. Normally, the storage batteries are arranged so that their long side surfaces face each other, but when they are arranged so that their short side surfaces face each other like a storage battery at the end of a row, FIG.
As shown in (a), it was necessary to provide a notch 5a for the connecting rod so as to face the intermediate portion of the short side wall of the cover. In addition, when it is arranged in the terminal unit, as shown in FIG.
As shown in (b), the upper wall of the cover is
The hole 4 for the upward lead wire had to be provided at a position almost directly above the negative electrode terminal. For this reason, there is a problem that the cost increases due to the additional work, and several types of covers that have undergone additional work are required at appropriate locations depending on the arrangement and arrangement of the storage batteries, which makes the parts management complicated. .

The present invention solves the above-mentioned conventional problems and provides a storage battery cover having a structure in which notches and holes can be easily processed in a short time according to the arrangement and storage method of the storage batteries. To aim.

[0005]

In order to achieve the above object, the present invention provides a storage battery cover arranged above a storage battery as follows. The top wall of the cover is a size that includes a small hole for inserting the tester pin at the time of voltage measurement, which is almost directly above the positive and negative terminals of the storage battery. A circular removable portion is provided. This is a hole for connecting the lead wire upward when it is arranged in the terminal portion. Further, a rectangular deletable portion, which is connected by the thin portion and is deleted as necessary, is provided so as to face the middle portion of the short side wall. This is a notch for the connecting rod when the short side surfaces such as the battery row ends are arranged so as to face each other.

The structure of the thin portion is composed of a plurality of thin connecting pieces or a thin portion formed by cutting, and the essential point is that the structure can be easily removed as necessary. There is no particular limitation as long as it is within the scope of the above. The shape of the removable portion is elliptical on the top wall and square on the side wall, but is not particularly limited as long as the lead wire and the connecting rod can pass therethrough.

[0007]

According to the present invention, the storage battery cover arranged above the storage battery is provided with the removable portion which is connected by the thin portion and can be deleted as necessary, so that a necessary portion can be pressed with a finger according to the arrangement of the storage batteries. Then, the hole or the notch can be provided easily and in a short time. It should be noted that if a simple cutting tool such as a cutter or a nipper is used, it can be deleted more easily and in a shorter time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings.

As one embodiment of the present invention, FIG. 1 shows a storage battery cover in the case of using a cathode absorption type seal type stationary lead storage battery. The storage battery cover 1 is a bottomless rectangular box-shaped body having the same size as a storage battery lid, and a circular cylindrical portion 2 provided at a central portion of an upper wall so as to project downward. A small hole 3 provided on the top wall at a position almost directly above the positive and negative terminals of the storage battery, and a long side surface of the side wall protruding downward along the entire circumference of the top wall, respectively, in parallel with the positive and negative terminals. And a rectangular notch 5 provided in the same manner, and a deletable portion shown below is provided therein.
