A new type of gel power battery terminal post sealing structure

Abstract

The present invention relates to a new sealing structure for colloid power battery terminals, which consists of copper terminals, O-shaped sealing rings, pool cover terminal connectors and tapered lead poles. The copper terminals are right-angled terminals. A welding hole is provided at one end of the copper terminal, a fixing hole is provided beside the welding hole, a pool cover end post hole is provided on the pool cover end post connector, and above the pool cover end post hole An annular groove is provided, a terminal fixing column is arranged beside the annular groove, and a terminal limit card is arranged beside the terminal fixing column. The invention has good sealing performance, no leakage of acid solution, avoids thermal runaway caused by electrolyte leakage, reduces corrosion risk, reduces internal resistance, improves current carrying capacity and ensures high-current safety performance.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a battery terminal post sealing structure. Background technique [0002] The current sealing structure of the terminal post of the gel battery is easily affected by a series of unstable factors such as the size deviation of the pole and the rubber ring, the surface roughness, and the deviation of the assembly operation, so that the fit cannot be completely sealed, and the poor sealing of the terminal post will cause acid leakage. , acid climbing phenomenon, and cause corrosion to the connection point and related components, affecting the normal use of the battery. After acid leakage, it must be cleaned up and pollute the environment. The current carrying capacity and high current safety cannot be guaranteed. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art, provide a kind of good sealing perf...
