There are two commonly used battery connectors: thimble and fragment connectors. Many battery connectors used in mobile phones are pins,
1. Working compression ratio
When the thimble connector is compared with the shrapnel-type connector of the same size, the compression is large and the contact is stable. The thimble battery connector works more effectively than the shrapnel-type connector.
2. Small space
Compared with the thimble type and shrapnel type with the same compression, the thimble type connector occupies less space on the PCB board. When the working position is 4mm and the compression is 1mm, the thimble connector occupies less space on the PCB board. Can be thin and miniaturized.
During the compression process, the contact position of the thimble connector does not change, and a stable connection point can be maintained to achieve stable electrical performance. The thimble battery connector is 2000 times, and the shrapnel type 5000 times. The thimble battery connector is safer than the shrapnel type.
From the above comparison and analysis of the needles, the thimble connector has many advantages over the shrapnel connector. The thimble connector can ensure the final contact pressure. The thimble connector has the life of the interface and the greater design freedom of updating than the shrapnel connector. In the future design of the top, many products have begun to adopt pin-type battery connectors.
