With the advancement of technology, mobile phones have become thinner and lighter. Fast charging has increased the demand for high-current connectors, etc., making the application of Pogo Pin connectors more frequent. Currently, Pogo Pin connectors are basically used in smart digital products on the market, and only some low-end products may still use shrapnel connectors. Below, we will discuss together what should be paid attention to when choosing Pogo Pin connectors and applying them to products.
1. The choice of Pogo Pin connector working stroke
Pogo Pin connector is selected according to the space and working stroke range of the product used. If the space is too small, the spring of the Pogo Pin connector will be excessively compressed, thereby affecting its service life; if the space is too large, it may cause poor contact, unstable impedance and instantaneous image interruption.
2. Selection of plating materials
The electroplating material is connected to the Pogo Pin, which has the functions of increasing conductivity, anti-oxidation, and anti-wear. Different materials also have different functions. For example, gold has good electrical conductivity. For high-current connectors, products with high impedance requirements generally choose electroplated gold.
3. What is the effect of the thickness of the coating?
Pogo Pin connector will produce certain friction and long-term wear due to contact during operation. The thickness of the coating has a great impact on the service life of the product. When used to a certain limit, the coating will wear out, which may cause excessive resistance and unstable impedance. The coating of 100,000 times POGO is definitely thicker than 10,000 times POGO, so please choose the coating requirements according to your needs when choosing products.
4. The impact of elasticity
The contact force of the spring thimble connector comes from the internal spring. The elastic force will directly affect the resistance and stability of the spring. Excessive elastic force will increase the friction coefficient and affect the service life of the spring.
