Structural analysis of Pogo Pin connector

　　As a connection device commonly used in high-demand electronic products such as mobile phones and wearable devices, the Pogo Pin connector plays an important role in connection and intercommunication; today, I will simply analyze the structure of the pogo pin connector;

　　The pogo pin consists of three parts: needle, needle tube, and spring.

　　1. Needle: There are three options for pogo pin needles.

　　Beveled needle

　　1. Inclined plane

　　In order to ensure 100% contact between the needle and the needle tube when working, we cut the end of the needle in contact with the spring into a bevel. This design concept can ensure a low and stable contact impedance, and can absolutely ensure the stable conduction of the product.

　　Anti-drilling needle

　　2. Reverse drilling

　　This design is the best choice for small size connectors. Can meet the elasticity requirements of customers. The length of the matching spring of this design 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.

　　Flat-bottomed needle

　　3. Flat bottom

　　In this design, the needle and the needle tube structure will not be able to contact under certain conditions, which will cause the current to not go through the needle tube, and the tube wall will follow the spring, which will cause the resistance to be too large, and the voltage will drop significantly, leading to electronic products Instantaneous power failure.

　　2. Needle

　　The design of the needle tube will be designed in accordance with the customer's structural space and product functional requirements as well as the guarantee of life. Can provide common and opposite design options.

　　Three, spring

　　Processing technology: Precise computer machining can ensure the dimensional accuracy, the accuracy can reach 0.02mm, and the product life can reach more than 100,000 times.

　　spring

　　Material: stainless steel SUS304, piano steel wire.

　　Finally, with the addition of insulating plastic parts, according to different spacing requirements, it can be combined into various pogo pin connectors.
