Description of thimble connector.Charging need

　　At present, there are two types of battery connectors commonly used in mobile phones: thimble-type and spring-type connectors. The battery connectors widely used in TCL mobile phones are of the thimble type, which has the following advantages compared with the shrapnel type battery connectors.

　　When the thimble type connector is compared with the spring type connector of the same size, the compression amount is large and the contact is stable

　　Remarks: The working situation in the above picture: the width size is 2.5mm, and the station position is 4.0mm;

　　Remarks: The thimble-type battery connector has a more effective working compression amount than the spring-type battery connector, which ensures the stability of the contact.

　　Compared with the thimble type and the spring type that use the same amount of compression, the thimble type connector occupies less PCB board space.

　　Remarks: When the working position is 4mm and the compression amount is 1mm, the thimble connector takes up less space on the PCB board. The thinning and miniaturization of the body can be realized.

　　Stability of touch position

　　When compressed, the contact point position of the thimble connector remains unchanged, which can maintain a stable connection point and obtain stable electrical performance.

　　Durability of multiple compressions

　　The thimble type is 20,000 times, and the shrapnel type is 5,000 times. The durability of the thimble type battery connector is stronger than that of the shrapnel type. The shape of the plastic gel and the combination of the thimble can be freely set, so the freedom of design is more prominent.

　　Through the above comparative analysis, the thimble-type connector has many advantages over the spring-type connector: it can make full use of the space of the PCB board; the thimble-type connector can ensure a high initial contact pressure, which is stable when compared with the previous spring-type connector. Contact pressure; thimble-type connectors have higher working life than spring-type connectors; high degree of design freedom. In the design of new models in the future, it is recommended that the battery connectors are all thimble-type battery connectors.
