spring thimble

Pogo pin, also known as pogopin, is a precision connector used in electronic products such as mobile phones. It is widely used in semiconductor equipment to connect electronic products. With the continuous improvement of living standards in recent years, some Modern electronic devices are emerging in an endless stream, and the demand for spring thimbles is increasing day by day. Taking human body wearable devices as an example, not only the connectors are required to be small in size, high current, but also required to have good waterproof performance. These are traditional shrapnel connections. What the device can't do, but the pogo pin connector can be easily controlled.

According to different application scenarios, the spring thimble has different appearances, but its structure is basically the same. At present, the spring thimble on the market generally consists of three parts, namely the needle shaft, the needle tube and the spring. Usually the needle shaft, the needle tube and the spring pass through the precision instrument Riveted into one body, the needle shaft, needle tube and spring are coaxial, and at least a part of the spring and the needle shaft are located in the needle tube, the bottom end of the needle tube is closed, and the top has a through hole for the needle shaft head to pass through, and the spring is usually precision The spring is used to limit the needle shaft through the riveting pressure between the needle shaft and the needle tube, so that the spring cannot push the needle shaft out of the needle tube. One end of the spring abuts on the bottom end of the needle shaft, and the other end abuts on the bottom of the needle tube. Limit the position to ensure the working stroke of the spring thimble. The entire surface of the spring thimble is generally gold-plated, and the unit price of the product is generally about 5 to 1 yuan, and the unit price is high and expensive. Dismantling, once the internal parts (such as springs) are damaged, the spring thimble can only be scrapped.
