pogo pinis a type of needle (Plunger), needle tube (Tube) and spring (Spring) after the three basic components are riveted by precision instruments The formed spring probe is also called pogo pin, pogo pin, spring probe, Spring Loaded, PogoPin connector.
1. 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 little space will over-compress the spring of the spring thimble and affect If the service life is too large, the contact may not be in place, the impedance will be unstable, and the phenomenon will be instantaneous.
2. Selection of plating materials:
The electroplating material in the spring thimble has the functions of increasing conductivity, preventing oxidation, anti-wear, etc. Different materials have different functions, such as gold, which has good conductivity. For high-current connectors, products with high impedance requirements generally choose electroplated gold.
3. What are the effects of electroplating film thickness on spring thimble:
The spring thimble will have a certain amount of friction when it is working because it must be in contact. It will wear out 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 electroplated layer is worn away, and 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.
4. The influence of elasticity:
The contact force of the spring thimble comes from the internal spring. The elastic force of the spring can directly affect the impedance and stability of the spring thimble; if the elastic force is too large, it will increase the friction The coefficient has an impact on the service life of the spring thimble.
