Choose different pogo pin thimble design structure

　　Pogopin is a relatively common spare part in life. Its electrical and mechanical properties are very good. Therefore, it is widely used in various electronic industries. Pogopin has several basic structures, including inclined surface structure, inclined surface plus ball structure, double contact structure and Anti-drilling structure. Several major types are usually divided into smt type, DTP type, double head type, wire bonding type, bending type, side post type. Different structure types will change in the application performance or environment of various products, so as to better application.

　　According to different electronic products, different pogopin thimble design structures need to be selected. Among them, the slope structure has the characteristics of small resistance and stability, which can ensure that the probability of instantaneous power failure when the needle shaft is in contact with the tube wall is low. If there is a need for high current, low contact impedance, and stable performance, it is recommended to use the inclined surface and ball structure, which has excellent electrical properties. The double contact structure can be used for high concentricity requirements. This design spring can be directly sleeved on the needle shaft, thereby reducing the chance of needle shaft shaking. At present, radio frequency pogopins are developing in the direction of lightness and smallness. The reverse drilling structure is also a good choice for small-sized equipment. In the case of limited space, hollowing out the needle shaft can get more and more Stable spring force and compression stroke.
