1.Pogo Pin needle design
The needle design requires the surface to be smooth into a small round hemisphere.
2. The slope design of Pogo Pin
In order to ensure that the needle is in 100% contact with the needle tube during operation, the end of the needle that contacts the spring is generally cut into a bevel. This design concept can ensure a low and stable contact impedance and can absolutely ensure the stable conduction of the product. This design of reverse drilling is the best choice for small size connectors, which can meet the elasticity requirements of customers.
3.Pogo Pin's flat bottom design
This kind of design will be unable to contact due to the structural difference between the needle and the needle tube, so that the current cannot go to the needle tube, and the wall of the needle tube goes straight along the spring, resulting in excessive resistance and a large arc drop in voltage.
Considerations for Pogo Pin Connectors
The electrical continuity of the contact pair when the Pogo Pin connector vibrates, impacts, and impacts under the specified frequency and acceleration conditions. The contact pair will instantaneously open circuit under this dynamic stress condition. The specified instantaneous time is generally 1μs, 10μs, 100μs, 1ms and 10ms. What should be paid attention to is how to judge the instantaneous failure of the contact pair. Now it is generally believed that when the voltage drop across the closed contact pair (contact) exceeds 50% of the electromotive force of the power supply, it can be determined that the closed contact pair (contact) is faulty. That is to say, there are two conditions for judging whether a momentary interruption occurs: duration and voltage drop, both of which are indispensable.
