What are the main components and functions of pogo pins?

The pogopin manufacturer pogo pin is mainly composed of three parts. One is the shell, that is, the needle tube, the other is the spring, and the third is the needle shaft. The needle tube is the main structure, which plays the role of shaping and supporting. Needle tubes are usually made of copper and gold-plated on the outside to resist oxidation and corrosion, improve mechanical and electrical properties, and play a role in better power and signal transmission. And the spring mainly plays the role of a jacking force, so that the needle shaft and the connection point are better contacted. According to different products, different parts and different connection requirements, the material and strength of the spring are also formulated differently. And most of the current also needs to pass through the spring, so it is sometimes necessary to gold-plate the spring.

The needle shaft is the contact part of the connection point, which is connected with the needle tube and achieves the effect of movement through the spring. Therefore, the strength and electrical performance of the needle shaft must be effective. Under long-term use, it must also have high durability and high wear-resistant requirements. For the needle tube, it also needs to be smooth inside so that the needle shaft can move better.

Pogo pins are not only widely used in the electronic communication industry, but also play an important role in automobile, medical, aerospace and other manufacturing industries, promoting the continuous development of technology and the times.
