What exactly affects the service life of the spring thimble?

　　The pogo pin is a spring-type probe formed by riveting the three basic parts of the needle (Plunger), the needle tube (Tube) and the spring (Spring) by precision instruments, also known as pogo pin, pogo pin, spring probe. Pin, Spring Loaded, PogoPin connector.

　　Selection of spring thimble working stroke:

　　When choosing a pogo pin, it must be determined according to the space of the product used, and the one within the working stroke range; if the space is too small, the spring of the pogo pin will be over-compressed, which will affect the service life, and if the space is too large, it may cause insufficient contact. , the impedance is unstable, and the transient phenomenon occurs.

　　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. Like gold, it has good conductivity. For high-current connectors, products with high impedance requirements are generally Will choose electroplating gold.

　　What effect does the thickness of the plating film have on the spring thimble:

　　The spring thimble will have a certain amount of friction due to its contact during operation, and it will wear for a long time. The thickness of the electroplating film will have a great influence on the service life of the product. When the use reaches 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-time pogo pin is definitely thicker than that of the 10,000-time thimble, so please be sure to choose the thickness of the electroplating film according to your needs when selecting products.
