Terminal sealing system of tubular colloid lead-acid storage battery

Abstract

A terminal sealing system of a tubular colloid lead-acid storage battery mainly comprises a lead column terminal and a battery cover. A terminal slot hole is arranged on the battery cover, the lower end of the terminal slot hole is a terminal port, the lead column terminal penetrates through the terminal port, the top portion of the lead column terminal and a connection line copper terminal are integrally embedded, an annular boss is arranged on the lead column terminal below the terminal port, an O-shaped ring, a pressure sleeve, an annular groove on the lead column terminal and a clamping ring clamped in the annular groove are sequentially arranged from the annular boss upwards, the terminal port is matched with the pressure sleeve, a rubber flat washer is arranged between the pressure sleeve and the terminal port, and a gap in the terminal slot hole is filled with polarity sealing glue. The terminal sealing system has the advantages of prolonging an acid climbing route of electrolyte which is permeated to the upper portion of a battery terminal column along a lead column and being good in sealing effects and high in firmness.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a terminal sealing structure and method of a tubular colloid lead-acid battery (OpzV). Background technique [0002] The terminal sealing problem of lead-acid battery has always been a very important problem. If the terminal sealing is not good, the lead-acid battery will cause acid leakage in the long-term floating state. Although the electrolyte exposed from the battery terminal is very small, it will not Affect the battery capacity, but for the user, the leakage of the terminal will inevitably affect the appearance of the battery, and corrode the battery rack, battery cabinet, battery connecting wire, copper bar and various power supply equipment of the user. At present, OPzV tubular colloidal lead-acid batteries are widely used in communication, electric power and new energy systems, etc., with good cycle performance, long float charge life, and high reliability of system o...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a terminal sealing structure and method for a tubular colloidal lead-acid battery, which can prolong the acid climbing path and increase the thickness of the sealing layer, effectively solving the problem of lead-acid battery lead in OPzV tubular colloidal lead-acid batteries above 2000Ah. Sleeve welding is not easy to achieve sealing, and the problem of acid leakage is prone to occur, especially the leakage problem caused by the terminal loosening caused by the growth of the plate in the later period of use
