PogoPin pogo pin connector is an electromechanical component that connects a conductor (wire) with an appropriate counterpart component to realize circuit connection and disconnection.
The first thing we need to understand is 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 connector is generally about 5000 times. When the specified mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the signal pin connector cannot exceed the specified value. Strictly speaking, the current mechanical life is just a rather vague concept. Mechanical life has a certain relationship with time. It is obvious that the situation is different after 500 times in 10 years and 500 times in 1 year. It's just that there is no more economical and more scientific method to measure it.
The number of contact pairs can be selected according to the mechanical life requirements 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. With a large number of contact pairs, its volume is naturally larger, and the total separation force is also larger. Under some conditions with high reliability requirements and permitting volume, the method of connecting two pairs of contact pairs in parallel can be selected to improve the reliability of the connection.
In the plug and socket of pogopin pogopin connector, the pins (male contacts) and jacks (female contacts) are usually interchangeable. In actual use, it can be selected according to the live conditions at both ends of the plug and socket. For example, if the socket is always live, you can choose a socket with a socket. Since the socket with a socket has its live contacts hidden in the insulator, it is difficult for the human body to touch the live contacts, so it is safer.
The electrical continuity of the contact pair when the pogopin spring pin connector is vibrated, impacted, and impacted under the specified frequency and acceleration is mainly considered. The contact pair will be instantaneously disconnected under this dynamic stress condition. The specified instantaneous time is usually 1μs, 10μs, 100μs, 1ms and 10ms. It is worth noting how to judge the instantaneous failure of the contact pair. It is now 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.
