The difference between Pogo Pin type and shrapnel connector
Commonly used battery connectors are in two forms: Pogo Pin type and shrapnel type. The battery connector widely used in mobile phones is the thimble type, which has the following advantages compared with the shrapnel type battery connector.
When the Pogo pin-type connector is compared with the shrapnel type connector of the same size, the compression amount is large and the contact is stable. The Pogo pin-type battery connector has a more effective working compression amount than the spring-type connector, ensuring the stability of the contact.
Compared with the thimble type and the shrapnel type using the same amount of compression, the thimble type connector occupies less PCB board space. When the working position is 4mm and the compression is 1mm, the Pogo pin-type connector takes up less space on the PCB board. It is possible to reduce the thickness and miniaturization of the body.
When compressed, the contact point position of the thimble connector remains unchanged, which can maintain a stable connection point and obtain stable electrical performance. The thimble type is 20,000 times, and the shrapnel type is 5,000 times. The durability of the Pogo pin-type battery connector is stronger than that of the shrapnel type. The shape of the plastic gel and the combination of the Pogo pin can be freely set, so the freedom of design is more prominent.
Through the above comparative analysis, the Pogo pin-type connector has many advantages over the shrapnel type: 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 shrapnel 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.
