A battery pole sealing process

Abstract

The invention relates to a battery pole sealing process, comprising the following steps: A1, making a pole hole on a battery cover, and simultaneously making a battery pole by casting; A2, making a double-wall heat-shrinkable sleeve, The wall heat shrinkable sleeve is installed at the lower part of the pole; A3, put wedge-shaped elastic body in the pole hole; A4, put the compression nut in the pole hole of the battery cover, tighten the compression nut, so that the compression nut is downward Press the wedge-shaped elastic body into the wedge-shaped hole; A5. Fill the gap between the pole and the pole hole of the battery cover with sealant. The invention solves the problem of accumulator acid leakage and greatly improves sealing reliability.

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...

[0002] The seal between the terminal pole and the battery cover of the valve-regulated sealed lead-acid battery has always troubled the battery industry, causing the battery to climb acid and leak

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, and lead and sealant are different materials, 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-wall heat-shrinkable sleeve, the effect is not ideal

[0003] There are deficiencies in the above methods, and it is impossible to fundamentally solve the leakage problem.
