Problems solved by technology

[0003] However, there are the following disadvantages in the prior art: 1. False welding and false welding are likely to be caused when the battery terminals and tabs are fused and welded, which seriously affects product quality and causes product scrapping; 2. At the same time, the harmful components of epoxy resin sealant pollute the environment , The longer curing time of epoxy resin

Abstract

The invention discloses a storage battery which comprises a safety valve, terminals, a battery cover, a battery jar, a pole plate group and an electrolyte, wherein the terminals are formed by embedding copper inserts into lead bodies; threads are formed on the copper inserts; error prevention locating surfaces of the copper inserts are matched with an error prevention locating surface of the storage battery cover; semicircular grooves are formed in the terminals and matched with semicircular bosses of a sealing ring; the lead bodies of the terminals are connected with pole plate tabs by comb tooth structures; chamfers are designed on the two sides of comb teeth; a device limiting the copper inserts to exceed the height of the surface of the storage battery cover; pole inversing of the storage battery during assembly is avoided; and the height of the storage battery is unified well. Fusion connection quality between the terminals and the tabs is reliable; tack welding and pseudo welding are not caused; the product quality is improved; a production process of the storage battery is simplified; a production cycle is shortened; and an environment is improved.

Description

technical field [0001] The invention relates to a storage battery. Background technique [0002] At present, there are two ways to seal the battery cover and the battery tank: heat sealing and glue sealing. The sealing of the terminal and the battery cover adopts rubber sealing technology: first pass the battery terminal through the terminal hole on the battery cover, then put the screw compression ring and the sealing ring on the battery terminal, and then tighten the screw compression ring to compress the pole The sealing ring makes the sealing ring seal the terminal tightly, and then fills the space formed by the terminal, the sealing ring, the pressing ring and the terminal hole with epoxy resin sealant, thereby forming a sealing device for the battery terminal. [0003] However, there are the following disadvantages in the prior art: 1. False welding and false welding are likely to be caused when the battery terminals and tabs are fused and welded, which seriously affe...
