Pogo pin readme.spring loaded pogo pins

　　Pogo pin is a precision connector used in electronic products such as mobile phones, and is widely used in semiconductor equipment for connection.

　　There are different appearances depending on the application, but as a whole 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 is energized or turned on, most of which are in contact with the copper wall through the oblique downward direction, and the spring bears a small amount, so the inner wall of the copper sleeve is required to be smooth. If the POGOPIN factory makes a non-beveled surface, but the bottom is flat, most of the current must 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 outage occurs when the current suddenly increases. (This is a little bit of my experience in the actual use process)

　　Pogo pin is a spring-type probe formed by riveting and pre-pressing the three basic components of needle shaft, spring and needle tube through precision instruments. There is 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 has a sharp needle, a grasping needle, a round needle, a knife needle, and the like. Pogo pins are generally used in precision connections in mobile phones, communications, automobiles, medical, aerospace and other electronic products, 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 precision connectors to reduce the weight of the connector and the volume of its appearance, which can make the connector more fine and beautiful.
