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. Several main types are generally divided into smt type, DTP type, double-headed type, wire bonding type, curved type, side pillar type, and different structure types are changed according to the application performance or environment of various products to better apply.
According to different electronic products, different pogopin thimble design structures should be selected. Among them, the inclined surface 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 surface with excellent electrical characteristics and a 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, thereby reducing the possibility of needle shaft shaking. At present, the pogo pin is developing in the direction of light weight and miniaturization. The back-drilling structure is also a good choice for small equipment. In the case of limited space, release the pin shaft to obtain more and more stable spring force and compression stroke. .
