Description

Technical Field

[0001] This utility model relates to battery packs. Background Technology

[0002] A battery pack includes a housing and a battery inside. The housing comprises a casing and a cover assembled together. The battery is positioned on a battery holder within the housing. One end of the battery has a terminal mounting bracket on which conductive terminals are mounted. The conductive terminals are electrically connected to the battery. The conductive terminals are plugged into a power-requiring device, enabling the battery to supply power to the device. Utility Model Content

[0003] The technical problem solved by this utility model is: how to seal the conductive terminals of a battery pack.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sealing structure for the conductive terminals of a battery pack, including a terminal peripheral structure disposed inside the housing and a terminal peripheral component fitted in the terminal peripheral structure, the terminal peripheral component surrounding the conductive terminals, and the housing having an insertion interface communicating with the terminal peripheral structure, characterized in that: sealant is injected into the terminal peripheral component, and a sealing element is provided between the terminal peripheral component and the terminal peripheral structure.

[0005] The sealant seals the inner bottom of the terminal outer casing, with the top of the conductive terminal near the connector. The sealant also seals the gap between the terminal outer casing and the terminal outer structure. In this way, the sealant and sealant can block moisture or liquid from the outside of the connector, preventing it from entering the battery pack.

[0006] Alternatively, the terminal peripheral structure is disposed on the cover of the housing, and the terminal peripheral structure is integrally formed within the cover. The insertion interface is disposed on the cover, and the cover is mounted on the housing.

[0007] The conductive terminal is mounted on the terminal mounting bracket, and the terminal peripheral component presses against the terminal mounting bracket. The sealant seals the inner bottom of the terminal peripheral component, as well as the gap between the terminal peripheral component and the terminal mounting bracket, and the gap between the conductive terminal and the terminal mounting bracket.

[0008] The terminal peripheral component has a positioning head, which mates with the terminal mounting bracket. The positioning head passes through the terminal mounting bracket and mates with a hole on the battery holder.

[0009] The outer wall of the terminal peripheral component is provided with a sealing ring groove, and the sealing component is a sealing ring that fits in the sealing ring groove.

[0010] The sealant of this invention seals the inner bottom of the outer part of the terminal and the sealing ring seals the outer gap of the outer part of the terminal. In this way, when the plug interface must exist, it can effectively prevent external moisture and dust from entering the battery pack through the plug interface. Attached Figure Description
