Four lifespans currently affecting the life of pogo pin

　　The pogo pin is a spring-type probe formed by the three basic components of a needle (Plunger), a needle tube (Tube) and a spring (Spring) after riveting by a precision instrument. It is also called a pogo pin, a pogo pin, and a spring probe. Pin, Spring? Loaded, PogoPin connector.

　　Spring thimble working stroke selection:

　　When choosing a spring thimble, it must be based on the space of the product used, and choose the one within the working stroke range; too small space will over-compress the spring of the spring thimble and affect the service life. If the space is too large, it may cause insufficient contact. , The impedance is unstable and the transient phenomenon appears.

　　Selection of electroplating materials:

　　Electroplating materials have the functions of increasing conductivity, preventing oxidation, and anti-wear in the spring thimble. Different materials have different functions. For example, gold has good conductivity. For high-current connectors, products with high impedance requirements are general Will choose electroplating gold.

　　What are the effects of plating film thickness on spring thimble:

　　The spring thimble will have a certain amount of friction when it is working, and it will be worn after a long time. The thickness of the electroplating film will have a great impact on the service life of the product. When used to a certain limit, the electroplating layer will be worn away. There may be phenomena such as excessive resistance and unstable impedance. The electroplating layer of the 100,000-times spring thimble must be thicker than that of the 10,000-times spring thimble, so please be sure to choose the plating film thickness requirements according to your needs when selecting the product.
