Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sealed lead-acid battery.

Configuration of conventional example and its problems A conventional sealed lead-acid battery will be explained below. FIG. 1 is an exploded perspective view of the container and lid of a sealed lead-acid battery, FIG. 2 is a perspective view of the back of the lid of a conventional sealed lead-acid battery, and FIG. 3 is a plan view of the back of the lid.

In FIGS. 1 to 3, 1 is a battery case of a sealed lead-acid battery, 2 is a plurality of cell chambers formed in the battery case 1,
Reference numeral 2' denotes a battery compartment compartment that divides the cell chamber 2, 3 a group of electrode plates housed in each cell chamber 2, 4 a pole pole of the electrode group 3, 5 a connection body between the electrode plate groups, and 6 a connector between the electrode plate groups. The frame of the battery case 1,
7 has a plurality of protrusions P, Q, and T surrounded by a lid partition wall on the back surface corresponding to the cell chamber 2, and the protrusions P and Q at the ends and the protrusion T in the middle are connected to each other. A connecting body accommodating part 9 into which the connecting body 5 between the electrode plate groups is inserted is formed between them, a plurality of protruding bodies P, Q, and T are formed as a lid formed to be inserted into the cell chamber 2, and 10 is one end. is connected to the pole post 4 of the electrode plate group 3, the other end projects upward through the through hole 11 provided at the end of the lid 7, and the bent part is inserted into the recess of the battery case 1. It is a Faston tab terminal.

However, in the above-mentioned conventional configuration, adhesive is injected from the connection body housing part 9 provided on the back surface of the lid 7 in order to fix the battery case 1 and the lid 7. There were problems in that the adhesive did not go around sufficiently, causing uneven adhesive flow and insufficient parts, and was very time-consuming.

Purpose of the invention The present invention solves the above-mentioned conventional problems.The present invention is a sealed lead-acid battery case in which the battery case and the lid are reliably bonded by efficiently pouring adhesive into the groove 8 provided on the back of the lid. The purpose is to provide storage batteries.

Structure of the invention The present invention relates to a sealed lead-acid battery consisting of a battery case containing a group of electrode plates in each cell chamber and a lid glued to the battery case. A groove into which the frame part and partition wall of the battery case are fitted is connected between the shaped parts, and a connection body housing part into which the connection body between the electrode plate groups is inserted near both left and right ends of the back surface, and the groove is provided in the center of the back surface. This is a sealed lead-acid battery with a lid that has an adhesive pouring groove that communicates with the battery. By providing the adhesive pouring groove at the center of the back surface of the lid, the adhesive can be poured easily and efficiently.

DESCRIPTION OF EMBODIMENTS FIG. 4 is a perspective view of the back of a lid of a sealed lead-acid battery according to an embodiment of the present invention, and FIG. 5 is a plan view of the back of the lid. Note that the same reference numerals are used for parts having the same configuration as in the conventional example, and explanations thereof will be omitted.

In FIGS. 4 and 5, R and S are intermediate protrusions obtained by dividing the protrusion T in FIGS. 2 and 3 into two,
They are separated by a central portion 12. central part 12
The grooves 8 and 9 communicate with each other and function as an adhesive pouring groove provided at the center of the back surface of the lid 5.

In the above configuration, the adhesive, e.g.
A two-component epoxy resin of 300 centipoise is applied to the connecting body housing portion 9 provided near both left and right ends of the back surface of the lid 7.
By injecting the adhesive from the central part 12 provided at the center of the back surface of the lid 7, the adhesive will flow into each groove 8 provided on the back surface of the lid 7 and the connection body accommodating portion 9, thereby preventing unevenness or insufficient parts. You can move around quickly without any problems.

Effects of the invention The present invention has a groove into which the compartment wall of the battery case fits into the back side of the lid, and a connection body housing part into which the connection body between the electrode plate groups enters near both left and right ends of the back side, and a connection body housing part into which the connection body between the electrode plate groups is inserted in the center of the back side. By providing a central part that serves as an adhesive pouring groove that communicates with the groove, and injecting the adhesive from the connecting body housing part and the central part, the adhesive quickly flows around each groove, eliminating uneven pouring and insufficient areas. This has the excellent effect of streamlining the battery assembly work without causing any problems, and it is possible to realize a sealed lead-acid battery in which the battery case and the lid are reliably bonded.
