Commonly used battery connectors are in two forms: pogo pins and shrapnel connectors. The battery connectors that are widely used in mobile phones are pogo pins. Compared with the spring-type battery connectors, what advantages do they have? Why are pogo pins better than shrapnel?
Compared with the shrapnel type connector of the same size, the pogo pin connector has a large amount of compression and stable contact. The pogo pin battery connector has a more effective working compression amount than the shrapnel type, ensuring the stability of the connection.
Comparing the pogo pin and shrapnel type with the same amount of compression, the pogo pin connector occupies less PCB board space. With a working position of 4mm and a compression of 1mm, the pogo pin connector takes up less space on the PCB board. The thinning and miniaturization of the body can be realized.
When compressed, the position of the contact point of the pogo pin connector remains unchanged, which can maintain a stable connection point and obtain stable electrical performance. The pogo pin is 20,000 times, and the shrapnel type is 5,000 times. The durability of the pogo pin charging 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.
