Factors affecting the service life of pogo pins

　　The pogo pin connector is an electromechanical component that connects the conductor (wire) with the appropriate mating component to realize the connection and disconnection of the circuit. In this hot summer, we should pay more attention to the safety of the details of life. The first thing we need to know is the life of the signal pin connector: the mechanical life of the pogopin spring thimble connector refers to the life of plugging and unplugging. Shaped metal plug-and-pull charging pin connectors are usually ruled around 5,000 times.

　　When reaching the specified mechanical life, the touch 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 vague concept. The mechanical life should have a certain relationship with the time. Obviously, the situation is different when it is used up 500 times in 10 years and 500 times in 1 year. It's just that there is no more economical and scientific way to measure it. First, the number of touch pairs can be selected according to the mechanical life of the circuit pogo pin connector, and the volume of the pogo pin connector and the total separation force should be considered. The larger the number of touch pairs, the larger the volume and the larger the total separation force. In some situations where high reliability is required and the volume is allowed, two pairs of touch pairs can be connected in parallel to improve the reliability of the connection. In the plug and socket of the pogo pin connector, the pins (male touch pieces) and jacks (female touch pieces) can generally be installed interchangeably. In actual use, it can be selected according to the live condition of both ends of the plug and socket. If the socket needs to be charged frequently, you can choose a socket with a jack. Because the socket with a jack, the live touch parts are buried in the insulator, and the human body is not easy to touch the live touch parts, which is relatively safe.
