Waterproof shell of waterproof power supply, waterproof power supply and manufacturing method of waterproof power supply

Abstract

The invention discloses a waterproof shell of a waterproof power supply, the waterproof power supply and a manufacturing method of the waterproof power supply. The waterproof shell comprises a shell,a cover, a sealing plate, two connection terminals and two output terminals, wherein the cover is matched onto an opening end of the shell, the sealing plate is arranged in the opening end of the shell, the two connection terminals are arranged on an inner surface of the cover and are isolated with each other, the two output terminals are arranged on an outer surface of the cover and are isolatedwith each other, the two output terminals are respectively connected with the two connection terminals, two output holes are formed in the sealing plate, a protruding first isolation wall and a firstprotruding wall are arranged on an inner surface of the cover, a protruding second isolation wall and a second protruding wall are arranged on the sealing plate, the second isolation wall is matched with the first isolation wall, the second protruding wall is matched with the first protruding wall, and the two connection terminals are insulated and isolated. By arranging the sealing plate in the waterproof shell, secondary sealing of a battery pack is achieved; and by arranging the isolation walls and the protruding walls on the sealing plate and the cover, isolation between a positive terminal and a negative terminal of the waterproof power supply is achieved.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a waterproof casing of a waterproof power supply, a waterproof power supply and a manufacturing method thereof. Background technique [0002] With the development of science and technology, the deepening of underwater exploration, the development of underwater equipment is becoming more and more common. Waterproof power supplies can be used in many industries such as diving entertainment, underwater salvage, aquaculture, and national defense. However, the production process and waterproof technology of the current underwater power supply are relatively backward, and the waterproof effect of the product is not good. Combining the current waterproof power supply production process and the actual application effect analysis of the product, it can be concluded that the current waterproof power supply has the following problems: [0003] 1. Corrosion of the positive output ter...

AI Technical Summary

Problems solved by technology

[0004] There is an assembly gap between the positive and negative output ports of the power supply and the waterproof case. Even if the positive and negative output ports and the waterproof case are integrally formed by injection molding, there is still a small gap between the output port and the waterproof case. When the power supply is in When working in a deep water area, the existence of water pressure causes water to seep into the battery from the contact gap to connect the positive and negative electrodes, resulting in electrochemical corrosion and dissolution at the output of the positive electrode.

[0005] 2. It is not easy to install and disassemble

[0006] When the waterproof power supply is assembled with the host, it also needs to be sealed and matched, which makes the assembly process complicated and inconvenient to install and disassemble

[0007] 3. The strength of the sealing joint is poor

[0008] The packaging method of the waterproof casing of most existing waterproof power supplies is: seal once at the assembly interface between the cover and the main body of the casing. Gaps or damage, loss of waterproof function

[0009] 4. Overflow glue leads to poor appearance

[0010] The glue sealing process is simple, the requirements for the mold are not high, and the sealing effect is good, but the amount of glue is difficult to control, too little glue can not achieve a complete sealing effect, too much glue will cause the glue to overflow, resulting in poor appearance
