Probe, also known as spring pin connector, is a precision connector commonly used in small electronic products such as mobile phones. In the main structure of the connector, the contact pin is composed of three parts: a needle, a spring, and a needle tube. During use, the needle will be compressed by a positive force after insertion, shortening from the free height to the working height. Pressing too little can cause impedance instability, while pressing too much can damage the needle and cause pin jamming. Therefore, this compression amount is usually one-third of the spring.
According to different installation methods, probes can also be classified into different types:
1. SMT style
Good stability, the bottom of the needle tube is designed with a flat bottom, making it easy for SMT patch welding.
2. DIP style
The tail of the needle shaft is equipped with a positioning pin, which will not deviate when welding with the PCB, resulting in excellent positioning effect.
3. Side mounted
Side mounted design can greatly reduce the thickness of products and is commonly used for battery connections in ultra-thin electronic products.
4. Bending type
The bending of the needle shaft tail can provide designers with more choices in space utilization.
5. Double headed
The dual head and dual spring design allows engineers to have more space elasticity in the bidirectional connection between boards.
