What factors are related to the lifespan of pogo pin connectors?.Solder-cup Pogo Pin

　　In this hot summer, we should pay more attention to the safety of life details. The first thing we need to know is the lifespan of the signal pin connector: the mechanical lifespan of the PogoPin pogo pin connector refers to the insertion and removal lifespan, while the circular metal plug-in charging pin connector is usually specified for approximately 5000 times.

　　When reaching the specified mechanical life, the contact resistance, insulation resistance, and withstand voltage of the signal pin connector should not exceed the specified values. Strictly speaking, the current mechanical lifespan is a vague concept. The mechanical lifespan should have a certain relationship with time. Obviously, if used 500 times in 10 years and 500 times in 1 year, the situation will be different. There is simply no more economical or scientific way to measure it.

　　The number of contact pairs can be selected based on the mechanical lifespan of the circuit pogopin pogopin connector, taking into account the size and total separation force of the pogopin pogopin connector. The more contact pairs, the larger the volume, and the greater the total separation force. In some cases where reliability is high and volume allows, two pairs of contact pairs can be used in parallel to improve the reliability of the connection

　　In the plug and socket of a pogopin pogo pin connector, the pin (male contact) and socket (female contact) can generally be interchanged and assembled. In practical use, the selection can be based on the electrification of both ends of the plug and socket. If the socket needs to be charged frequently, a socket with a socket can be chosen because the live contacts of the socket with a socket are buried in the insulator, making it relatively safe for the human body to come into contact with the live contacts.

　　The main consideration is the electrical continuity of the contact pairs of pogopin pogopin connectors during vibration, impact, and collision processes under specified frequency and acceleration conditions. Under this dynamic stress condition, the contact pair will instantly open. The specified transient time is generally 1 μ s. 10 μ s. 100 μ s. 1ms and 10ms. It should be noted how to determine the instantaneous failure of contact pairs. It is now widely believed that when the voltage drop between the two ends of a closed contact exceeds 50% of the power supply electromotive force, it can be determined that a fault has occurred in the closed contact pair. That is to say, there are two conditions for determining whether an instantaneous interruption has occurred: duration and voltage drop, both of which are indispensable.
