Abstract

The invention provides a button cell structure. The button cell structure comprises a metal shell, a roll core accommodated in the metal shell, a supporting metal structure arranged on the upper surface of the roll core and a metal cover body arranged on the metal shell, wherein the metal shell is of a hollow cylindrical structure with an opening in one end, an inner cavity of the metal shell is an accommodating cavity used for accommodating the roll core and electrolyte, the supporting metal structure comprises a supporting metal shell electrically connected with the roll core and an FPC piece arranged on the supporting metal shell, and an installation groove used for installing the FPC piece is formed in the supporting metal shell in a concave mode. According to the button cell structure provided by the invention, the space can be fully utilized to improve the capacity of the cell, the FPC can balance a magnetic field generated when the cell works, the occurrence of bottom noise is reduced, even the bottom noise is not generated, and when the current exceeds a safety range, a circuit for FPC protection is disconnected, so that the cell can be protected, and safety risks such as cell leakage, fire or explosion are prevented.

Description

Technical field[0001]The present invention relates to a button battery structure.Background technique[0002]With the popularization of Bluetooth headphones, users have improved experience in experience, while the existing TWS earphone capacity is low, it is prone to safety risks such as leakage, drums, and the battery will generate a magnetic field when working, and the headphone interference produces a bottom noise. Impact the customer experience.Inventive content[0003]Based on this, it is necessary to provide a button battery structure for the above problems.[0004]A linkable battery structure, a metal housing, a core of a core in a metal housing, a support metal structure disposed on the upper surface of the core and a metal cover provided on the metal housing, the metal housing In the hollow cylindrical structure of one end, the inner cavity of the metal housing is a housing chamber for receiving the core and an electrolyte, the support metal structure comprising and a support met...
