Pin structure type of POGOPIN pogo pin connector

　　1. Beveled needle: In order to ensure that the POGO PIN connector needle is in 100% contact with the POGO PIN connector needle tube during operation, the end of the needle that is in contact with the spring will be cut into a bevel. This design concept can ensure low and stable contact resistance, and can absolutely guarantee the stable conduction of the product.

　　2. Anti-drilling needle: This design is the choice of POGO PIN connector with small size, which can meet customer's elastic requirements. The length of the matching spring of this design can exceed the length of the needle tube. In the case of limited space, the design of reverse drilling can obtain stable elastic force and stroke.

　　3. Flat-bottomed needle: This design may not be in contact with the POGO PIN needle and the POGO PIN needle tube structure under certain conditions, which will cause the current to not go through the needle tube, and the tube wall will go along the spring, which will lead to excessive resistance. If the voltage is too large, the voltage will drop significantly, resulting in unstable current of electronic products.
