The pogo pin spring thimble is a common connector in our lives. You may not have noticed it. It is precise and small, but it plays a very important function, such as: mobile phones, smart watches, drones, Bluetooth headsets, e-cigarettes and many more. These all need to use the spring thimble, which mainly plays the function of connecting, charging and transmitting signals in the device. Below, the editor wants to share with you today: the design and structure principle of pogo pin spring thimble needle and the structural characteristics of six common spring thimble.
The design and structure principle of pogo pin spring thimble needle:
1) Needle bevel structure: pogo pin spring thimble is a design concept that can ensure low and stable contact impedance, and can ensure the stable conduction of the product.
2) Needle punching structure: Pogo pin spring thimble has a matching spring length that can exceed the length of the needle tube. In the case of limited space, the design of reverse drilling can obtain stable elastic force and stroke.
3) Flat-bottomed needle structure: This design is because the pogo pin spring thimble needle and the spring thimble needle tube structure will not be able to contact under certain conditions, which will cause the current to be unable to go through the needle tube, and the tube wall will follow the spring, which will cause If the resistance is too large, the voltage will drop drastically, which will cause the current instability of electronic products.
