Nowadays, everyone uses numerous electronic devices, mobile phones, computers, etc. Various products representing the technology of the times flood people's lives, making our life, work and study more convenient and faster. But you may not know the existence of pogo pins. What is the composition of the pogo pin? What role does it play? Next, the pogo pin manufacturer-Senbo Technology will explain it for everyone.
Pogopin, also known as pogopin, is widely used in various precision electronic instruments. It mainly plays the role of connection and is used to transmit electrical energy and signals.
The pogo pin is mainly composed of three parts. One is the housing, which is the needle tube, the second 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. The needle tube is usually made of copper material, and the outer wall is gold-plated to play the role of anti-oxidation and anti-corrosion, and improve the mechanical and electrical performance, and play a better role in the transmission of electrical energy and signals. The spring mainly acts as a top force to make better contact between the needle shaft and the connection point. 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 sometimes the spring needs to be gold-plated.
The needle shaft is the contact part for the connection point. It is connected with the needle tube and is moved by 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.
