9 Pin Spring Loaded Pogo Pin Connector

9 Pin Spring-loaded Pogo pin connector

What are the precautions for the selection of pogo pin connectors? With the rapid development of technology, mobile phones are becoming thinner and lighter. Fast charging has increased the demand for high-current connectors, and the application of pogo pin connectors (spring thimble connectors) has become more frequent. At present, the smart digital products on the market basically use pogo pin connectors, and only a few low-end products may still use shrapnel-type connectors;

Pogo pin connector work stroke selection:

The choice of pogo pin connector should be determined according to the product space used, and the one within the working stroke range should be selected; too little space will over-compress the spring of the pogo pin connector, affecting the service life, and too much space may cause contact failure When it is in place, the impedance is unstable and instantaneously disconnected. The 9 Pin Shaped customization  Spring-loaded Pogo pin connector Makes the most of space.

Plating material selection:

Electroplating materials in pogo pin connectors can enhance conductivity, prevent oxidation, wear resistance, etc. Different materials have different functions. Gold has good electrical conductivity. It is usually used for high-current connectors and products with high impedance requirements. Choose electroplated gold.

What are the effects of plating film thickness:

Right angel 90-degree bending Pogo pin connector will wear out due to contact friction for a long time during work. The thickness of the electroplating film has a great influence on the service life of the product. When used to a certain limit, the electroplated layer is worn out, and the resistance may be too large, and the impedance may be unstable. The electroplating layer of 100,000 times pogo pin is thicker than that of 10,000 times. Therefore, the electroplating requirements must be selected according to the needs when selecting the product.

The influence of elasticity:

The contact force of the pogo pin connector comes from the internal spring. The elastic force of the spring has a direct effect on the impedance of the pogo pin; too much elastic force will increase the friction coefficient and affect the service life of the pogo pin.
