Abstract

PURPOSE:To maintain gastightness and enable an electrolyte to be prevented from crawling up from within a battery by enlarging the length of a boundary between a cover and a bushing with a threaded section continuous to the internal surface of the battery. CONSTITUTION:In forming a terminal sealing section, an electrode pole 2 constituting a plate group is inserted in the bushing 3' of a cover 1, and the crown of the pole 2 is thereby inserted through the electrode pole insertion hole 9 of a terminal 6. The terminal 6 is thus placed on the bushing 3'. Then, lead 5 is fused and caused to fall on the section of the hole 9 of the terminal 6, using a gas burner. At the same time, the pole 2, bushing 3' and terminal 6 are also fused and integrated with one another via deposition. The terminal sealing section so formed allows the enlargement of the length of a boundary between the bushing 3' and a resin material forming the cover 1'. An electrolyte can be thus prevented from crawling from within a battery. In addition, good gastightness can be maintained over a long term.

Description of the Related Art Conventionally, as a terminal sealing portion of a sealed lead-acid battery, a lid integrally formed with a resin material is formed up to the bottom of a bushing inserted in the lid, and the lid 1 and the pole 2 are inserted. The adhesive 4 is applied and solidified on the outer circumference of the upper boundary surface between the bushing 3 and the bushing 3 to keep airtightness and prevent the sulfuric acid from crawling up. In addition, 5 is a lead portion formed on the top of the pole 2, and 6 is a terminal portion.

な気密を保つことができないという問題点があった。The method of coating and solidifying the adhesive 4 on the upper outer periphery of the boundary surface between the lid 1 and the bushing 3 is as follows. 3 is applied to the outer periphery of the upper part of the boundary surface with the adhesive 3 and the post adhesive 4 is dried. However, the adhesive 4 used and the solvent for cleaning the adhesive 4 are organic solvents, which may adversely affect the human body. On the other hand, if the adhesive 4 is not used on the boundary surface as described above, there is a problem that the electrolytic solution crawls from the gap between the boundary surface between the lid 1 and the bushing 3, and good airtightness cannot be maintained.

ることである。The object of the present invention is to maintain the airtightness at the interface between the lid and the bushing without using an adhesive agent, which is equivalent to the structure when an adhesive agent is used, and to crawl the electrolyte from the inside of the battery. An object of the present invention is to provide a terminal sealing portion that can prevent rising.

なる封口部を形成するものである。In order to solve the above-mentioned problems, the present invention provides a threaded portion on the inner surface of a bushing to be inserted into a lid so that when the lid and the bushing are molded, the threaded portion also has a resin portion. Using a lid having a bushing integrated with each other, a sealing portion including a bushing provided with a screw portion, a pole, and a terminal is formed.

At this time, not only the uneven portion 7 of the bushing 3 ', but also the screw portion 8 is integrally molded with the resin portion forming the lid 1'. In this case, the length of the boundary surface between the resin portion of the lid 1'and the bushing 3'is long enough to prevent the sulfuric acid from creeping up from the inside of the battery.

を防止し、良好な気密を長期間保つことができる。In forming the terminal sealing portion, the pole 2 which constitutes the electrode plate group is inserted into the bushing 3'of the lid 1 ', and the top of the pole 2 is inserted into the pole insertion hole 9 of the terminal 6. Then, the terminal 6 is placed on the bushing 3'so that it is inserted. Then, the lead wire 5 is connected to the pole pillar insertion port 9 of the terminal 6 by the gas burner.
And the poles 2, the bushings 3 ', and the terminals 6 are also melted to integrally weld them. The terminal sealing portion thus obtained can increase the length of the boundary surface between the bushing 3'and the lid resin member forming the lid 1 ', and prevents the electrolytic solution from creeping up from the inside of the battery. However, good airtightness can be maintained for a long time.

と同程度である。By adopting such a terminal sealing structure, as compared with the conventional structure in which the upper part of the boundary surface between the bushing 3 and the lid 1 is fixed with the adhesive 4, no adhesive is used, and therefore the human body is adversely affected. Moreover, since the steps of mixing, filling, and drying the main agent and the curing agent are eliminated, the number of manufacturing steps can be reduced. Further, when the structure is such that no adhesive is used for the terminal sealing portion, about 20% of the sulfuric acid creeps up, but the terminal sealing portion of the present invention can remove sulfuric acid from the inside of the battery without using the adhesive. Crawling up and airtightness are similar to those of the terminal sealing part in which the upper part of the interface between the bushing 3 and the lid 1 is fixed with the adhesive 4.
