Problems solved by technology

Due to factors such as the large current used on the ship and the ship’s easy vibration, the welding of the lead sleeve and the terminal is undoubtedly a major hidden danger. Once the welding process is improper or there are pores, cracks or impurities such as oxides in the welding point, when the large current is discharged It is easy to burn the external terminals, causing safety accidents

Embodiment 1

[0018] Example 1, please refer to image 3 with Figure 4 , a kind of lead-acid accumulator that the present embodiment provides, comprises: battery body and external connection terminal, and battery body comprises pole and battery cover 40, and battery cover 40 is provided with via hole, and external connection terminal comprises integrally formed lead sleeve 70 and terminal 60, the pole passes through the hole and connects with the lead sleeve 70; the battery body includes a positive pole part 11 and a negative pole part 12; The holes include positive vias 51 and negative vias 52 . The lead sleeve and terminal of the external terminal provided in this embodiment are integrally formed. Compared with the split design in the prior art, the forming process is saved, the welding process is reduced, and at the same time, air holes and cracks due to improper welding process or welding points are avoided. Or the potential safety hazard caused by impurities such as oxides.

Embodiment 2

[0023] Example 2, please refer to Figure 5 to Figure 6 , a method for manufacturing a lead-acid battery provided in this embodiment, including methods such as external terminal casting, external terminal and battery cover joining, such as Figure 5 shown.

[0024] Wherein, the casting method of the external terminal is: pouring lead alloy melt into the mold of the external terminal, and forming the external terminal including the lead sleeve and the terminal after cooling.

[0025] The joining method of the external terminal and the battery cover is as follows: the lead sleeve on the external terminal is pre-placed in the battery cover mold, and then injected into the plastic melt, cooled and molded, and the external terminal and the battery cover are combined into one.

[0026] In this embodiment, it is preferable that the lead sleeve of the external terminal passes through the via hole on the battery cover. Therefore, in theory, as long as the size of the via hole on the b...

Abstract

The invention discloses a lead-acid battery, which includes a battery body and an external terminal. The battery body includes poles and a battery cover; the battery cover is provided with through holes; the cell body comprises an anode part and a cathode part; the poles comprise a positive pole in the anode part and a negative pole in the cathode part; the through holes include an anode hole and a cathode hole; the external terminal includes integrally molded lead sleeve and terminal; and the poles pass through the through holes and are connected with the lead sleeve. The external terminal and the lead sleeve provided by the invention are integrally molded, so as to save a molding process and reduce a welding procedure compared with the prior art of split design, thereby avoiding safety hidden dangers caused by improper welding process or pores, cracks or oxide inclusions in welding point.

Description

technical field [0001] The invention belongs to the field of lead-acid batteries, in particular to a lead-acid battery suitable for ships and a manufacturing method thereof. Background technique [0002] Lead-acid batteries have been widely used because of their low price, reliable quality, large capacity range, easy maintenance, and long service life. With the development of the modern logistics industry, the shipping industry has also been greatly developed, and the demand for lead-acid batteries used on ships is also increasing. Due to the particularity and harshness of the environment and conditions used on ships, lead-acid batteries are required to have the characteristics of large starting current, anti-vibration, and safe and reliable battery performance. [0003] At present, the basic structure of lead-acid batteries used on ships includes the battery body and the external terminals connected to the battery body. The external terminals are used for electrical connec...
