Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a detachable battery connector for mobile phone batteries. Background Technology

[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is an electrical system that provides a separable interface for connecting two electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic devices; it is the bridge between the two. Examples include power plugs / sockets, IC sockets, telephone line plugs, etc.

[0003] Electronic connectors are widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easily plugged in and out, or it can be a permanent connection between electrical equipment or wires. Electronic connectors are generally divided into two categories: female connectors and male connectors. Female connectors and male connectors are used in sets, and by mating the female connector and male connector, the circuit is made conductive to achieve data transmission.

[0004] With the continuous development of society and economy and the continuous improvement of people's living standards, mobile phones, as a portable communication tool, have been welcomed and loved by people, and have played an indispensable role in people's work and life, providing convenience for people's work and life. According to people's different needs, mobile phones have been further innovated.

[0005] Currently, mobile phone batteries are generally designed as an integral part of the phone, meaning they are not removable. If the battery malfunctions or ages, users cannot replace it themselves and must take it to a professional repair shop. Repairs are time-consuming and costly, causing inconvenience. Furthermore, the disassembly and reassembly process during repair can easily damage other components, posing a significant repair risk. Some phones have removable batteries, but the plug and socket are designed for side assembly. When assembling the plug and socket, the plug is inserted into the socket from the side, requiring the circuit board to reserve space on the side of the plug or socket. This wastes internal space, hindering miniaturization and failing to meet current requirements. Therefore, it is necessary to research a new technical solution to improve these issues. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology by providing a detachable battery connector for mobile phone batteries. This effectively solves the problems in the existing technology where mobile phones and batteries are generally non-detachable, making it difficult for users to replace batteries themselves if they malfunction or age, causing inconvenience and posing significant repair risks. In some mobile phones, the batteries are detachable, and the plug and socket are designed with a side-mounted assembly structure. Therefore, the circuit board on the mobile phone needs to reserve a certain amount of space on the side of the socket or plug, resulting in wasted internal space and hindering the miniaturization design of the mobile phone.
