What role does the pogo pin connector play?
Nowadays, we can see all kinds of technology products of the times everywhere in our daily lives, which makes everyone's life, work and study more and more convenient and faster. But you may not know the existence of pogo pins. What is the composition of a pogo pin connector? What role does it play?
Pogo pin, or pogo pin, is widely used in various precision electronic instruments. Its main function is to connect and transmit electrical energy and signals.
The pogo pin is mainly composed of three parts: the housing (that is, the needle tube), the spring, and the needle shaft. The main structure is a needle tube, which plays the role of shaping and supporting. The needle tube is generally made of copper material, and the outer wall is gold-plated, mainly for anti-oxidation and anti-corrosion, but also to improve the mechanical and electrical performance, and achieve better power and signal transmission. The main function of the spring is the top force, allowing the needle shaft and the connection point to make better contact. According to different products, different parts, and different connection requirements, the material and strength of the spring are also made differently. And most of the current also needs to pass through the spring, so sometimes the spring needs to be gold-plated. The function of the needle shaft is to connect the contact parts of the connection point with the needle tube and achieve the effect of movement through the spring. Therefore, the strength and electrical performance of the needle shaft must be achieved. Under long-term use, it is required to achieve high durability and high Wear-resistant performance. For the needle tube, it also needs to keep its inside smooth to allow the needle shaft to move better.
