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 pogo pin connector refers to the
plug-in life, and the circular metal plug-and-pull charging pin connection The
device is usually specified as about 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 life is a vague concept. The
mechanical life should have a certain relationship with 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 contact pairs can be selected according to the
mechanical life of the circuit pogopin connector, and the volume of the pogopin
pogo pin connector and the total separation force should be considered. The
larger the number of contact pairs, the larger the volume and the larger the
total separation force. In some cases where the reliability is high and the
volume is allowed, the method of connecting two pairs of contact pairs in
parallel can be used to improve the reliability of the connection.
In the plug and socket of the pogopin connector, the pins (male contacts)
and jacks (female contacts) can generally be assembled 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 live contact of the socket with a jack
is buried in the insulator, and it is not easy for the human body to touch the
live contact, which is relatively safe.
The main consideration is the electrical continuity of the contact pair of
the pogopin connector during vibration, shock and collision under the specified
frequency and acceleration conditions. The contact pair will open
instantaneously under this dynamic stress condition. The specified transient
time is generally 1μs, 10μs, 100μs, 1ms and 10ms. The thing to pay attention to
is how to judge the momentary failure of the contact pair. It is now generally
believed that when the voltage drop across the closed contact pair (contacts)
exceeds 50% of the power supply electromotive force, it can be determined that
the closed contact pair (contacts) fails. That is to say, there are two
conditions for judging whether an instantaneous interruption occurs: duration
and voltage drop, both of which are indispensable.
