Burn-in pole lug clamping device

Abstract

The invention provides a burn-in pole lug clamping device, which comprises a fastening piece, a positive pole comb plate, a negative pole comb plate and a press strip which is sandwiched between the positive pole comb plate and the negative pole comb plate, wherein the positive pole comb plate and the negative pole comb plate are tightly compressed through the fastening piece; two opposite surfaces of the positive pole comb plate and the negative pole comb plate are provided with a positive pole lug placing position and a negative pole lug placing position respectively; one side of the press trip towards the positive pole comb plate is provided with positive comb teeth, and one side of the press strip towards the negative pole comb plate is provided with negative comb teeth; a positive accommodating cavity matched with the shape of a positive pole lug is enclosed by the positive comb teeth and the positive pole lug placing position; and a negative accommodating cavity matched with the shape of a negative pole lug is enclosed by the negative comb teeth and the negative pole lug placing position. In the burn-in pole lug clamping device, the accommodating cavities matched with the pole lugs are correspondingly enclosed by one side of the press strip and the positive pole comb plate as well as the other side of the press strip and the negative pole comb plate respectively, so that the pole lugs cannot slip off from the cavities, and the phenomenon of false welding is prevented; and the accommodating cavities are tightly attached to the pole lugs without gaps, and lead leakage in the welding process can be prevented.

Description

technical field [0001] The invention relates to a storage battery, in particular to a tab clamping device used for welding the tabs of the storage battery. Background technique [0002] A battery is a battery that can regenerate internal active materials by charging after discharge, store electrical energy as chemical energy, and convert chemical energy into electrical energy again when it needs to be discharged, also known as a secondary battery. It is precisely because of the characteristics of batteries that can store electrical energy that batteries can be seen in more and more fields. [0003] Among many batteries, lead-acid batteries have been widely used in important fields of the national economy in recent years due to their advantages of low price, reliable quality, large capacity range, easy maintenance, and long service life, becoming the most widely used battery. It is precisely because lead-acid batteries are getting more and more attention from all parties, so...
