Pogo pin is a kind of precision connector used in mobile phones and other electronic products, which is widely used in semiconductor devices. It has different appearance according to different applications, but on the whole, pogo pin has a precision spring structure inside. The surface of the product is generally gold-plated, and the spring should also be gold-plated when the process is required. Most of the thimble contacts with the copper wall by slanting downward, and the spring bears a small amount, so the inner wall of the copper sleeve is required to be smooth. If pogopin factory makes a flat bottom instead of oblique section, most of the current will pass through the spring, so the requirement for the spring will be very high.

Pogo pin is a kind of spring probe, which is made up of needle shaft, spring and needle tube and pre pressed by precision instrument. There is a precision spring structure in pogo pin. The surface coating of pogo pin is generally gold-plated, which can better improve its anti-corrosion function, mechanical properties, electrical properties and so on. The needle tip has pointed needle, grasping needle, round needle, knife needle and so on. Pogo pin is generally used in precision connection of mobile phone, communication, automobile, medical, aerospace and other electronic products, which can improve the corrosion resistance, stability and durability of these connectors. Because pogo pin is a very fine probe, it can reduce the weight and appearance volume of the connector and make the connector more fine and beautiful.
