What is a charging needle?

　　What is a charging needle?Charging needles are also called charging probes. They are the touch media for electrical tests and are high-end precision electronic hardware components. The charging pin is divided into a pogo pin and a general pin when used as a circuit board test. When using the pogo pin, it is necessary to make a test mold according to the wiring of the tested circuit board, and usually, a mold can only test one type of circuit board; when the general-purpose pin is used, it only needs to have enough points. Test the circuit board, so most charging pin manufacturers now produce different types of charging pins.

　　Intrinsic factors such as the probe core area, material conductivity, and insulating layer conductivity of the charging probe determine the current carrying capacity of the probe. The thicker the probe core, the higher the purity of copper in the conductive material, and the better the thermal conductivity of the insulating material.

　　The pogo pin has a layer of gold on its surface, which improves its corrosion resistance, mechanical properties, and electrical properties. Because of its small size, high precision and light weight, pogo pins are widely used in aviation, aerospace, military communications and military electronics; secondly, they also involve the fields of automobiles and car navigation that are inseparable from us; in addition, medical equipment , wireless equipment, data communication equipment, etc. also have its presence.

　　In recent years, electronic products have become lighter and portable, and charging pin manufacturers are not far behind. The stable touch resistance of the charging pin ensures the stability of electronic equipment. The charging pin needs to be plugged and used repeatedly during operation. The life span can reach about 50,000 times. And it also has the performance of waterproof, moisture-proof and shock-proof, so the occurrence and development of the charging needle is also another milestone in my country's electronic products.
