　　Pogopin pogo pin connector life

　　PogoPin pogo pin connectors are electromechanical components that connect conductors (wires) with appropriate counterpart components to realize circuit connection and disconnection.

　　In this hot summer, we should pay more attention to the safety of life details. First of all, we need to understand the life of the signal pin connector: the mechanical life of the PogoPin spring pin connector refers to the plug life, and the round metal plug-in charging pin is connected. The device is usually specified as about 5000 times. When the specified mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the signal pin connector should not exceed the specified value. Strictly speaking, the current mechanical life is a fuzzy concept. Mechanical life should have a certain relationship with time. After 500 times in 10 years and 500 times in 1 year, the situation is obviously different. It's just that there is no more economical and more scientific method to measure it.

　　First, the number of contact pairs can be selected according to the mechanical life of the pogopin pogopin connector of the circuit, and the volume of the pogopin pogopin connector and the size of the total separation force should be considered at the same time. The number of contact pairs is large, of course, the volume is large, and the total separation force is relatively large. In some cases where the reliability is high and the volume is allowed, two pairs of contact pairs can be used in parallel to improve the reliability of the connection.

　　In the plugs and sockets of pogopin spring pin connectors, the pins (male contacts) and jacks (female contacts) can generally be assembled interchangeably. In actual use, it can be selected according to the live conditions at both ends of the plug and socket. If the socket needs to be charged frequently, you can choose a socket with a socket, because the socket with a socket has its live contacts buried in the insulator, and the human body is not easy to touch the live contacts, which is relatively safe.

　　The main consideration is the electrical continuity of the contact pair of the pogopin pogopin connector under specified frequency and acceleration conditions when it vibrates, impacts, and collides. 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.
