Internal structure of pogo pin

　　There is a precision spring structure inside the pogo pin. The surface of the product is generally gold-plated, and the spring should also be gold-plated when required by the process.

　　The thimble is energized or conductive. Most of the thimbles contact the copper wall diagonally downward, and the spring bears a small amount. Therefore, the inner wall of the copper sleeve is required to be smooth.

　　Electrical characteristics will actively find the path with the lowest resistance value to conduct current. For example, the POGOPIN factory is made into a non oblique section, but the bottom is flat. Most of the current will be conducted through the spring, and the requirements for the spring will be high.

　　Pogo pin is a kind of spring probe formed by three basic parts, namely needle shaft, spring and needle tube, after riveting and preloading with precision instrument, with a precise spring structure inside. The surface coating of pogo pin is generally gold plated, which can better improve its anti-corrosion function, mechanical properties, electrical properties, etc. The needle tip is provided with a sharp needle, a grasping needle, a round head needle, a knife shaped needle, etc. Pogo pin is generally used for precise connection of mobile phones, portable electronic devices, communications, automobiles, medical, aerospace and other electronic products, which can improve the anti-corrosion, stability and durability of these connectors. As pogo pin is a very fine probe, its application in precision connector can reduce the weight and appearance volume of the connector and make the connector more delicate and beautiful.

　　Different structures have different amounts of current, and different structures can also be used in different functional designs. The number of contact points will also affect the amount of current.
