Pogo pin is a kind of spring type probe which is formed by riveting the three basic parts of the needle, tube and spring through the precise instrument. It is also called spring needle, spring thimble, spring loaded and pogopin connector. The bottom of pogo pin's plunger is usually a slope structure. The function of the slope structure is to ensure that the pogo pin can keep the needle in contact with the inner wall of the tube when it is working, and let the current mainly pass through the gold-plated needle and tube to ensure the stability and low impedance of the pogo pin. Pogo pin is generally used in the precise connection of mobile phone, communication, automobile, medical treatment, aerospace and other electronic products; because pogo pin is a very fine probe, its volume can be very small, so it can reduce the weight of connector, save space and beautify the appearance of products (such as ultra-thin mobile phones, smart watches and other products). The classification of pogo pin connector is as follows: 1. Vertical type 2. Right angle 3. Double ended pin connection. 4. Floating pin connection is the most commonly used pogo pin type. The product has good stability and the bottom plane is welded with PCB pad. Suitable for surface sticking and hand welding. Advantages of pogo pin: pogo pin can better transmit high-frequency signal of antenna. Compared with antenna shrapnel, pogo pin has smaller distributed capacitance and inductance due to shorter current path at the same working height, especially in high frequency band, which is more conducive to impedance matching. Based on the same working height, the pogo pin is much higher than the shrapnel in the self resonant frequency band, and the loss is smaller, which is conducive to the efficient transmission of high-frequency signals. Pogo pin can be more flexible in signal transmission in metal frame design, so that the antenna radiation is more far away from the motherboard and its components, which is more conducive to the performance of the antenna. At the same time, the contact and assembly scheme of pogo pin are also more flexible. In the design of metal battery cover, metal frame and ultra-thin model, the space can be better
