Description

Technical Field

[0001] This utility model relates to the field of battery holders, and in particular to an integrally molded battery holder. Background Technology

[0002] A battery holder is a device in electronic devices used to secure batteries and provide a stable electrical connection. It is typically a key component of electronic devices. A battery holder is an electronic connector installed in electronic devices to connect the battery to the circuit board, acting as a bridge between the two. Its core functions include securing the battery, conducting current, and protecting the battery.

[0003] Battery holders can be categorized according to different battery types, including button battery holders, cylindrical battery holders, and irregularly shaped battery holders. Battery holders are widely used in electronic devices across various fields, such as consumer electronics, medical devices, automotive electronics, and smart home devices.

[0004] Current battery holders typically consist of an insulating body and multiple terminals. The insulating body has several mounting slots. During assembly, the terminals must be manually installed into these slots. While this design is simple, the assembly process is cumbersome and time-consuming. The small size of the terminals makes manual handling and assembly inconvenient, leading to low production efficiency, high labor costs, and increased production time. Furthermore, gaps exist between the terminals and the mounting slots after assembly, allowing moisture and dust to penetrate, resulting in poor sealing. Additionally, the connection between the terminals and the insulating body is not robust enough. Repeated battery insertion and removal or impacts can easily cause the terminals to loosen, damaging the battery holder, leading to poor contact, affecting product operation, and resulting in lower product quality, shorter lifespan, and failure to meet current requirements. Therefore, it is necessary to research a new technical solution to improve current battery holders. Utility Model Content

[0005] In view of the above, this utility model addresses the shortcomings of existing technologies by providing an integrated molded battery holder. This effectively solves the problems of existing battery holders, such as numerous assembly steps, cumbersome operation, inconvenience in manual handling and assembly due to the small size of the terminals, low production efficiency, high labor costs, gaps between the terminals and the mounting slots after assembly allowing moisture and dust to seep in, poor sealing performance, and an unstable connection structure between the terminals and the insulation body, which can easily cause the terminals to loosen and damage the battery holder when the battery is repeatedly inserted or removed or subjected to external impacts.

[0013] As a preferred embodiment, the welded portion has an extension portion bent and extended at one end away from the longitudinal connection portion. This extension portion is embedded in the insulating body, which effectively enhances the stability of the connection structure between the terminal and the insulating body and improves the quality of the product.

[0014] As a preferred embodiment, the insulating body is provided with a partition, which is disposed in the insertion cavity and located between two adjacent terminals.
