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 is a spring-type probe formed by riveting pressure needles (Plunger), the needle tube (Tube) and the spring (Spring) three basic components through precision instruments, also known as spring needle, spring thimble, spring probe, Spring Loaded, PogoPin connector. The bottom of the Pogo Pin's pin (Plunger) is usually a bevel structure. The function of the bevel structure is to ensure that the Pogo Pin keeps the needle (Plunger) in contact with the inner wall of the needle tube during operation, and the current mainly passes through the gold-plated needle (Plunger) and the needle tube. (Tube) to ensure Pogo Pin stability and low impedance. Pogo Pin is generally used in precision connection in mobile phones, communications, automotive, medical, aerospace and other electronic products; since the Pogo Pin is a very fine probe, the volume can be made very small, so the application can be reduced in precision connectors. The connector's weight, space-saving, and beautifying the appearance of the product (such as: ultra-thin mobile phones, smart watches and other products).
Pogo Pin Industry Trends
★ Jumper can be realized between board and board, no longer tied by the line.
★ Small size fine type
★ High current
★ High durability
Pogo Pin can better transmit the high frequency signal of the antenna
Compared to antenna springs, Pogo Pin has a smaller distributed capacitance and distributed inductance at the same working height due to the shorter current path, especially at high frequencies, which is more conducive to impedance matching.
Based on the same working height, Pogo Pin is much higher than the shrapnel in the self-resonant frequency band, and the loss is smaller, which is favorable for efficient transmission of high-frequency signals.
Pogo Pin can provide more flexible signal transmission in the metal frame design, so that the antenna radiation is further away from the motherboard and its components, which is more conducive to the performance of the antenna. At the same time, Pogo Pin's contact and assembly solutions are also more flexible in the metal battery cover. , Metal frame, ultra-thin model design has better use of space.
Pogo Pin can realize high current connection scheme
Pogo Pin makes it easier to achieve a waterproof structure
Pogo Pin's precise and stable connection facilitates RF signal transmission
When the Pogo Pin is used for the antenna connector, a more stable connection point can obtain more stable RF performance without frequency offset.
