Storage battery pole sealing process

Abstract

The invention relates to a storage battery pole sealing process. The sealing process comprises the steps of A1 manufacturing a pole hole in a storage battery cover, and manufacturing a pole of a storage battery by a casting method; A2 manufacturing a double-wall heat-shrinkable sleeve, and installing the double-wall heat-shrinkable sleeve at the lower part of the pole; A3 arranging a wedge-shaped elastic body in the pole hole; A4 arranging a compression nut in the pole hole of the storage battery cover, and screwing down the compression nut, so that the compression nut downwards compresses the wedge-shaped elastic body in the wedge-shaped hole; and A5 filling a gap between the pole and the pole hole of the storage battery cover with a sealant. The problems of acid leakage and liquid leakage of the storage battery are solved, and the sealing reliability is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of battery production, in particular to a battery pole sealing process. Background technique

[0002] The seal between the terminal pole and the battery cover of valve-regulated sealed lead-acid batteries has always troubled the battery industry, causing acid leakage of batteries. Existing sealing method has following deficiencies: 1, " O " shape sealing ring is line contact, see figure 1 , due to the line contact, the contact distance is short, the electrolyte is easy to climb out along the "O"-shaped sealing ring and the pole, and the sealing effect is not ideal. 2. The sealant is directly sealed. Since the pole material is lead, which is different from the sealant, the contact is not firm and reliable, and the electrolyte in the battery will slowly crawl out along the contact point. 3. The heat-shrinkable sleeve is used to seal, which is a single-wall heat-shrinkable sleeve, see figure 1 , not a double...
