Abstract

PROBLEM TO BE SOLVED: To prevent adhesive deficiency which may occur unless a projection is positioned at the center of a recess by disposing a plurality of vertical ribs for restricting an interval between the surface of the projection and the inner face of the recess in either one of the inner face of the recess formed on a battery jar cover and the surface of the projection. SOLUTION: A recess 12 is formed on the upper opening of a battery jar 1, and further, a projection 13 to be fitted into the recess 12 is formed on the lower opening of a battery jar cover 2. Vertical ribs 15, 16 are arranged at an adequate interval at the surface of the projection 13. The ribs 15, 16 keep the interval between the surface of the projection 13 and the inner face of the recess 12 constant. Consequently, an adhesive layer 20 having a predetermined thickness can be interposed between the surface of the projection 13 and the inner face of the recess 12, the adhering portion between which has uniform adhesive strength over the entire circumstance.

2. Description of the Related Art The battery case and lid of a lead storage battery are usually made of synthetic resin. Then, as a method of sealing the opening of the battery case with a lid, a structure such as polypropylene that is heat-welded, and a structure in which the battery case and the lid are fitted with an uneven portion,
There is a method of bonding with an adhesive. In the latter bonding method, the bonding portion has a structure as shown in FIG. 6, for example. That is, the recess 23 is provided on the end surface of the opening of the battery case 21, and the protrusion 24 that fits into the recess 23 is provided on the opening of the battery cover 22. Then, the concave portion 23 of the battery case 21 is filled with the adhesive 25, the battery case lid 22 is covered, and the convex portion 24 is fitted into the concave portion 23. At this time, the convex portion 24 is not necessarily located at the center of the concave portion 23. For example, when the convex portion 24 is biased to one side in the concave portion 23 as shown in FIG. 6, the adhesive is extruded to the outside of the concave portion 23 on the biased side as shown by 25a. Therefore, a sufficient amount of adhesive is not secured, and the adhesive strength becomes weak in this portion.

If there is such a weak adhesive strength,
When the battery is transported or installed, the lid comes off, or even if the lid does not come off, the gas generated during overcharge is leaked to the outside, resulting in various problems such as a decrease in the amount of electrolytic solution. In particular, in sealed lead-acid batteries used for power distribution equipment, substation power supplies, or building emergency lighting power supplies, the size of the battery case is large, so the fitting part between the concave part and the convex part may be bent at the center. Since there are many deviations, poor adhesion is likely to occur. Further, in the structure in which the convex portion is fitted to the bottom of the concave portion, no adhesive agent is interposed between the tip of the convex portion and the bottom of the concave portion, which is disadvantageous in terms of adhesive strength.

SUMMARY OF THE INVENTION In view of the above, the present invention fits a concave portion provided on the end face of one opening of the battery case and a convex portion provided on the end face of the other opening, and An object of the present invention is to eliminate adhesion failure due to the protrusion not being located at the center of the recess in a lead storage battery that is bonded by an adhesive. It is another object of the present invention to provide a lead storage battery having a high adhesive strength by allowing an adhesive to intervene between the tip of the convex portion and the bottom of the concave portion.

By these ribs 15 and 16, the distance between the surface of the convex portion 13 and the inner surface of the concave portion 12 can be made constant. Therefore, a layer of the adhesive 20 having a constant thickness is interposed between the surface of the convex portion 13 and the inner surface of the concave portion 12, and the adhesive portion between the two has uniform adhesive strength over the entire circumference. The ribs 15 and 16 do not need to be provided at corresponding positions on the outer surface and the inner surface of the convex portion, respectively, but it is advantageous to provide them in correspondence so that the convex portion 13 is located at the center of the concave portion 12. .

Ribs 14 are provided on the bottom surface of the recess 12 of the battery case 1 at appropriate intervals. The rib 14 has a width of about 2 m
m, height about 1 mm, provided at intervals of about 150 mm. Due to the ribs 14, the convex portion 13 does not reach the bottom of the concave portion 12, so that an adhesive layer having a constant thickness can be interposed between the tip of the convex portion 13 and the bottom surface of the concave portion 12. Further, due to the action of the ribs 14, a constant gap is formed between one edge portion of the concave portion 12 of the battery case 1, the inner edge portion in the example of FIG. 2 and the corresponding step portion of the battery case lid 1. . Then, by fitting the convex portion 13 into the concave portion 12 filled with the adhesive 20,
The adhesive pushed out by the convex portion 13 enters the above-mentioned gap and serves to increase the adhesive strength. The ribs 14 are preferably provided at positions deviated from the ribs 15 and 16 in the vertical direction. If these ribs are in the same position,
This is because the portions where the adhesive does not intervene overlap each other to locally form a portion with weak adhesive strength.
