What is pogo pin?

　　Pogo pin is a kind of precision connector used in mobile phones and other electronic products. It is widely used in semiconductor equipment for connection.

　　There are different appearances according to different applications, but overall there is a precision spring structure inside the pogo pin. The surface of the product is generally gold-plated, and the unit price of the product is generally about 5 to 1 yuan.

　　The thimble realizes energization or conduction, and most of it is in contact with the copper wall through the oblique lower side, and the spring bears a small amount, so the inner wall of the copper sleeve is required to be smooth. For example, if the POGOPIN factory has a non-beveled surface, but a flat bottom, most of the current will be conducted through the spring, and the requirements for the spring will be very high. Of course, it is necessary to ensure that the power failure occurs when the current suddenly increases.

　　Pogo pin is a spring-type probe formed by the three basic components of needle shaft, spring and needle tube after being riveted and preloaded by precision instruments. There is a precision spring structure inside. The surface coating of pogo pin is generally gold-plated, which can better improve its anti-corrosion function, mechanical performance, electrical performance and so on.

　　The needle tip has sharp needles, grasping needles, round needles, knife-shaped needles, etc. Pogo pins are generally used for precision connections in electronic products such as mobile phones, communications, automobiles, medical, aerospace, etc., which can improve the corrosion resistance, stability, and durability of these connectors. Since the pogo pin is a very fine probe, it can be used in a precision connector to reduce the weight of the connector and the volume of the appearance, which can make the connector more refined and beautiful.
