What are the precautions for the selection of pogo pin connector?

　　What are the precautions for the selection of pogo pin connector?With the rapid development of science and technology, mobile phones are becoming thinner and thinner. Fast charging increases the demand for high current connectors, which makes the application of pogo pin connectors more frequent. At present, most of the intelligent digital products on the market use pogo pin connectors, and only a few low-end products may still use shrapnel connectors;

　　Working stroke selection of pogo pin connector:

　　When selecting the pogo pin connector, it should be determined according to the product space used, and the one within the working stroke range should be selected; if the space is too small, the spring of the pogo pin connector will be excessively compressed, which will affect the service life. If the space is too large, the contact may not be in place, and the impedance will be unstable and transient will occur.

　　Selection of electroplating materials:

　　Electroplating materials in pogo pin connector can enhance conductivity, prevent oxidation, anti-wear and so on. Different materials have different functions. Gold has good conductivity. For high current connector and high impedance products, electroplating gold is usually used.

　　What are the effects of plating thickness

　　Pogo pin connector will wear when it works because of contact friction for a long time. The thickness of electroplated film has a great impact on the service life of the product. When using to a certain limit, the electrodeposited coating is worn, and the resistance may be too high and the impedance is unstable. The electroplating layer of 100000 times of pogo pin is thicker than that of 10000 times, so the electroplating requirements must be selected according to the demand when selecting products.

　　The effect of elasticity:

　　The contact force of the pogo pin connector comes from the internal spring, and the spring force has a direct impact on the impedance of the pogo pin; if the spring force is too large, the friction coefficient will be increased and the service life of the pogo pin will be affected.
