The battery contact probe belongs to a functional probe and is not used for testing. It mainly serves as a connection and has the characteristics of good conductivity, low resistance, and high stability.
Charging pin, also known as "pogopin". It consists of three parts: spring, needle tube, and needle tip. The charging pin belongs to the functional pin and is not used for testing. It mainly plays a role in connecting and conducting, and has the characteristics of good conductivity, low resistance, and high stability.
Charging needles are mainly used for conducting charging tests on components such as smart homes, smart wearables, and automotive electronics.
