Commonly used battery connectors have two forms: spring thimble and shrapnel type connectors. However, mobile phones mostly use spring thimble connectors as battery connectors. This is because the spring thimble connector has more advantages compared with the shrapnel type connector.
Compared with the spring-type connector of the same size, the spring thimble connector has a more effective working compression, which can ensure the stability of the contact and obtain stable electrical performance.
When using the same compression spring thimble and shrapnel type for comparison, the spring thimble connector occupies less PCB board space. The body can be thin and miniaturized.
The mechanical life of the pogo pin is generally up to 20,000 times, while the shrapnel type is generally only 5,000 times. Therefore, the durability of the pogo pin battery connector is stronger than that of the shrapnel type.
