Embodiment Construction

[0007] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0008] The battery terminal shown in FIG. 1 mainly includes an aluminum pile core 1 and a holding seat 2 covering the aluminum pile core. The holding seat 2 is formed by die-casting, and the die-casting process adopts traditional technology. It mainly includes the following three processes:

[0009] First: Insert the aluminum pile core 1 as a core into the die-casting mold;

[0010] Second: pour molten lead-tin alloy die-casting melt into the die cavity of the die-casting mold, and die-cast the holder 2 covering the aluminum pile core;

[0011] Third: After natural cooling, open the mold to obtain battery terminals with high dimensional accuracy, high density and high surface finish.

[0012] The storage battery terminal provided by the present invention greatly reduces the cost compared with the storage battery terminal structure using copp...

Abstract

The present invention relates to a storage battery terminal which mainly comprises a tubular pile core and a lead or capsule metal holding seat for covering the pile core, wherein, the pile core is made of aluminum. The invention changes the prior copper pile core to the aluminum pile core; apart from keeping electricity conductibility, intensity and so on of the storage battery terminal, the most prominent property of the invention is to reduce raw material cost greatly.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery terminal structure. Background technique [0002] The traditional battery terminal structure mainly includes a tubular pile core and a lead or lead-tin alloy holding seat covering the pile core, but currently the pile core is processed by a solid copper rod. And as the price of copper continues to soar sharply, the manufacturing cost of battery terminals also increases one after another. Therefore, in the current situation of shortage of resources and vigorous promotion of energy saving and material reduction, it has become an urgent task to propose a battery terminal that can save materials and reduce costs while maintaining its original performance. However, new technologies or new inventions that can save costs on battery terminal structures and materials are still relatively rare. Contents of the invention [0003] The technical problem to be solved by the pre...
