Example Embodiment

[0016] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] like image 3 As shown, a tubular colloidal lead-acid battery terminal sealing structure mainly includes a battery terminal 1, an O-shaped sealing rubber ring 7, a pressure sleeve 4, a flat rubber gasket 5, a semicircular snap ring 2, an ABS engineering plastic ring 3 and a battery cover 6.

[0018] The terminal 1 is composed of a lead column and a copper core inlaid inside. There is an annular boss 8 in the middle of the lead column of the terminal 1, and an annular groove 9 is formed near the outer circumference of the lead column near the copper core. It prolongs the terminal leakage time.

[0019] O-type sealing rubber ring 7, pressure sleeve 4, semicircular snap ring 2, are sleeved on the outer circumference of the lead column, the pressure sleeve 4 presses the O-type sealing rubber ring 7 tightly, and fits tightly with the lead column,...

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...
