2. Description of the Related Art In recent years, lead-acid batteries have been widely manufactured from small to large as a power source for small electronic devices, a power source for automobiles, a computer backup power source, and an emergency power source for large facilities. And the actual Kaihei 2-1
As described in Japanese Patent No. 13260, the pole pillar was penetrated through the battery inner lid. The conventional lead-acid battery will be described below.

In FIG. 2, 1 is a terminal plate, 2 is a fitting portion 13a with the upper end of the battery case, and a recess 16a for accommodating the joint between the pole 6 and one end of the terminal 1 and the pole 6 are provided. A battery inner lid having a through hole 12a penetrating therethrough, 3 a battery case, 4 an electrode plate group welding shelf, 5 an adhesive for sealing the periphery of the welded portion of the pole 6 and the terminal plate 1 and the recess 16a, Reference numeral 7 is an adhesive that bonds the upper end of the battery case 3 to the fitting portion 13a of the battery inner lid, and 8 is a group of electrode plates. The operation of the lead storage battery configured as described above will be described below. First, the electrode plate group 8 is welded to the electrode pillars 6 on the electrode plate group welding shelf 4, and after being inserted into the battery case 3, the battery inner lid in which the adhesive 7 is poured into the upper end portion of the battery case 3. Is fitted to the fitting portion 13a. At that time, the tip of the pole 6 penetrates the through hole 12 a formed in the battery inner lid 2. The adhesive 7 is cured in a high temperature drying furnace, and one end of the terminal pillar 1 is combined with one end of the pole 6 exposed on the upper surface of the battery inner lid 2 by gas or TIG welding (tungsten inert gas welding). , One end of the pole 6 is melted and joined to one end of the terminal board 1. In order to fix the terminal plate 1 and to seal the recess 16a of the battery inner lid 2, the adhesive 5 is poured into the recess 16a of the battery inner lid 2 and cured in a high temperature drying oven.

[0004]

However, in the above structure, the fitting portion 13 between the upper end of the battery case 3 and the battery inner lid is used.
In order to cure the adhesive 7 for adhering a, the periphery of the welded portion of the pole 6 and one end of the terminal plate 1 and the adhesive 5 for sealing the recess 16a of the battery inner lid, the battery must be put in a high temperature drying oven twice. In addition, since the one end of the pole 6 and the one end of the terminal plate 1 are welded, a large-scale facility is required, which complicates the manufacturing process.

The present invention solves the above-mentioned conventional problems, and provides a lead-acid battery having a small size and excellent characteristics, in which the curing process of an adhesive is simplified without using a pole. With the goal.

[0006]

In order to achieve the above object, a lead acid battery of the present invention comprises a recess for accommodating a joint between an electrode plate welding shelf made of lead or a lead alloy and one end of a terminal plate, and a battery battery. A battery inner lid having a fitting portion with the upper end of the tank, a through hole penetrating the other end of the metal terminal plate, and one end of the terminal plate by welding or soldering the electrode plate group welding shelf The terminal plate joined to, the recess containing the joint between the electrode plate group welding shelf and one end of the terminal plate, and the adhesive is poured into the fitting portion with the upper end of the battery case. It is glued.

[0007]

With this configuration, one end of the terminal plate is directly connected to the electrode plate group welding shelf, the pole column is not required, and the battery inner lid that accommodates the joint between the electrode plate group welding shelf and one end of the terminal plate is eliminated. Since the adhesive that seals the recess and the adhesive that bonds the fitting part between the upper end of the battery case and the battery inner lid can be poured at the same time, the adhesive curing step can be performed only once. Become.

EXAMPLE A lead-acid battery according to an example of the present invention will be described below.
A description will be given with reference to the drawings.

In FIG. 1, 1 is a metal terminal plate, 2 is a fitting portion 3a with the upper end of the battery case 3, and a pole plate group welding shelf 4 is shown.
A battery inner lid having a recessed portion 9a accommodating a joining portion between the terminal plate 1 and one end of the terminal plate 1 and a through hole 2a through which the other end of the terminal plate 1 penetrates;
7 is an adhesive that bonds the fitting portion 3a of the battery inner lid 2 to the upper end of the battery case 3, 8 is an electrode plate group, and 9 is a joint portion between the electrode plate group welding shelf 4 and one end of the terminal plate 1. Recess 9 of the battery inner lid 2 containing
It is an adhesive for sealing a. The operation of the lead storage battery configured as described above will be described below. First, solder one end of the terminal plate 1 and the electrode plate group welding shelf 4 or use TIG.
Join by welding (tungsten inert gas welding),
It fits into the recess 9a of the battery inner lid 2. At this time, the terminal board 1
The other end of the battery penetrates the through hole 2a of the battery inner lid 2 to
The fitting operation is temporarily stopped at the position on the upper surface of the battery, the adhesive 7 is poured into the fitting portion 3a of the battery case 2, and the adhesive 9 is further poured into the concave portion 9a of the battery inner lid 2 to bring the battery to a predetermined position. The inner lid 2 is pushed in and the above adhesives 7 and 9 are cured in a high temperature drying furnace.

[0010]

As is apparent from the above description of the embodiments, according to the lead-acid battery of the present invention, one end of the terminal plate is directly joined to the electrode plate group welding shelf, and the recess of the battery inner lid around the joint is formed. By pouring the adhesive into the
Also, the adhesive poured into the recess of the battery inner lid can be poured at the same time as the adhesive that bonds the upper end of the battery battery case and the fitting portion of the battery inner lid, so the adhesive curing step is performed once. It is possible to realize a small lead acid battery with excellent characteristics by simplifying the adhesive curing process.
