Description

Technical Field

[0001] The utility model relates to the technical field of button batteries, in particular to a button battery which is easy to position and assemble. Background Art

[0002] Button batteries are widely used in all aspects of life, especially in computer motherboards, watches, calculators, Bluetooth headsets, toy walkie-talkies and other related products and fields.

[0003] With the increasing development of electronic products, button batteries have been widely used in various micro-electronic products due to their lightness and compactness. They are mainly used as backup power sources for various electronic products, such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, CPC cards and electronic displays, and people's requirements for button batteries are also increasing.

[0004] Button batteries must not only be easy to carry, but also require ultra-high capacity and service life, so the development of new button batteries can meet market demand.

[0005] For example, the prior art Chinese patent publication number "CN218632236U" provides a button battery that is easy to assemble, including an upper cover, an outer shell and a battery cell. The battery cell is located in the inner cavity of the outer shell, and the battery cell is used to store electrical energy. The upper cover is located at the opening of the outer shell; the upper cover includes a cover body, and the cover body includes an outer ring piece, a limiting portion and an inner ring piece. The limiting portion connects the inner edge of the outer ring piece with the outer edge of the inner ring piece, and the limiting portion is annular. The limiting portion protrudes toward the inner cavity of the outer shell relative to the outer ring piece, the limiting portion is connected to the inner wall of the outer shell, and the outer ring piece is connected to the open end face of the outer shell.

[0006] When assembling the upper cover and outer shell, the limiting portion limits the upper cover in the radial direction of the outer shell, while the outer ring limits the upper cover in the axial direction of the outer shell. This prevents the upper cover from misalignment, reducing the difficulty of assembly. Because the outer ring is precisely connected to the open end face of the outer shell, welding is less likely to produce empty welds, and welding slag is less likely to enter the inner cavity of the outer shell, improving battery quality, production yield, and production efficiency.

[0007] Existing button batteries that are easy to position and assemble have both ends of the button battery welded and fixed after the battery cell is installed inside the shell. This makes the button battery inconvenient to disassemble, assemble, replace and maintain, affects the stability of the button battery installed inside the shell, and fails to position it stably. At the same time, the shell of the button battery is relatively simple, easily damaged by bumps and lacks protection. Utility Model Content
