Basic Introduction to POGO PIN (Spring Pin) Connector

　　Depending on the application, there are different appearances, but overall, the pogo pin has a precision spring structure inside. The surface of this product is usually gold-plated, and if there are requirements for the process, the spring should also be gold-plated.

　　The top pin is used to achieve power or conductivity, and most of it contacts the copper wall diagonally downwards. The spring bears a small amount, so it is required that the inner wall of the copper sleeve be smooth. If POGOPIN factory makes the bottom flat instead of a sloping surface, most of the current will have to be conducted through the spring, which will have high requirements for the spring.

　　Pogo pin is a spring type probe formed by riveting and preloading three basic components: needle shaft, spring, and needle tube with precision instruments. It has a precise spring structure inside. The surface coating of pogo pins is generally gold-plated, which can better improve their anti-corrosion function, mechanical properties, electrical properties, etc. Needle tips include pointed needles, grasping needles, round headed needles, knife shaped needles, etc. Pogo pins are generally used for precision connections in electronic products such as mobile phones, communications, automotive, medical, aerospace, etc., which can improve the corrosion resistance, stability, and durability of these connectors. Due to the fact that pogo pins are delicate probes, their application in precision connectors can reduce the weight and size of the connector, making it more delicate and aesthetically pleasing.
