Pogo pin is a commonly used part in daily life. Due to its excellent electrical and mechanical properties, it is widely used in various electronic industries. The main types are generally divided into SMT type, DTP type, double head type, wire bonding type, bending type and side column type, and different structure types are changed according to the application performance or environment of various products for better application.
According to different electronic products, different pogopin thimble design structures should be selected. The inclined plane structure has the characteristics of low resistance and good stability, which can ensure that the possibility of instantaneous power failure when the needle shaft contacts the tube wall is low. When high current, low contact resistance and stable performance are required, it is recommended to use an inclined plane with excellent electrical characteristics and ball structure. The double contact structure can be used for high concentricity requirements. This design spring can be directly sleeved on the tail needle of the needle shaft, so as to reduce the possibility of shaking of the needle shaft. At present, pogo pin is developing towards lightweight and miniaturization. The reverse drilling structure is also a good choice for small equipment. Under the condition of limited space, release the needle shaft to obtain more and more stable spring force and compression stroke.
