[0037] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. As mentioned throughout the specification and claims, "including" is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0038] In addition, the terms "first", "second", etc. are only used for descriptive purposes to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship, and cannot be understood as indicating or implying relative importance. The term "and / or" in this application is only a description of the association relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "or" relationship.

[0039] In the utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0040] The inventors found that existing batteries usually use hardware terminal outputs, and the hardware terminal outputs must be connected to the battery using a connector. In this structure, since there is not enough space buffer design between the connector and the terminal, it will cause power failure, resulting in unusability. In addition, existing battery products do not fully consider the battery's anti-drop, waterproof, dustproof and other issues, resulting in poor structural stability and safety of the battery, which can easily cause the battery's quality to deteriorate or even cause damage to the battery, resulting in a shorter battery life.
