Comb type polar post for accumulator through-hole welding

Abstract

Disclose is a comb-shaped terminal post used in a through-wall welding of storage battery, belonging to the field of lead-acid storage battery manufacturing technology, which essentially comprises a terminal post conductive electrode (1), a short step (2) which is disposed on one end of the terminal post conductive electrode (1) and small comb-shaped teeth (3) which are arranged on the short step (2), and the like, wherein the number of teeth of the small comb-shaped teeth (3) is 3 to 6; and the using process is that as long as the comb-shaped terminal post is placed on the welding mold (5), the small comb-shaped teeth (3) which are disposed at the bottom thereof are melted together with the plate lugs (4) of the polar plate so as to form a cylinder manifold. The overall structure is rational in design, so that the comb-shaped terminal post can be firmly combined together with the cylinder manifold by making use of the small comb teeth part of the terminal post without affecting the designed size of the battery, so as to improve the performance of the storage battery; and false soldering and inveracious soldering of the terminal post can be effectively prevented, so as to improve the high current discharge capacity of the storage battery and extend the service life of the battery.

Description

technical field [0001] The invention relates to a comb-shaped pole post for battery through-wall welding, belonging to the technical field of lead-acid battery manufacture. Background technique [0002] At present, for the large-capacity batteries of lead-acid batteries used for starting automobiles, the middle pole used for penetrating the wall is generally a small 7-shaped structure composed of conductive electrodes and short steps. It is easy to produce false welding when welding the electrode group, and the firmness is not enough. At the same time, when the battery is discharged with a large current during use, there are many cases of breakage between the bus bar and the pole, which will easily lead to the scrapping of the battery. Seriously affected the quality and service life of the battery. Contents of the invention [0003] The object of the present invention is to provide a comb-shaped post for battery through-wall welding with reasonable design, which can effec...
