In this hot summer, we should pay more attention to the safety of life. The first thing we need to know is the life of the signal needle connector: the mechanical life of the POGOPIN POGO PIGO PIN connector refers to the plug -in life. The circular metal plug -in charging needle connector is usually about 5,000 times.
When reaching the prescribed mechanical life, the contact resistance, insulation resistance and resistance of the signal needle connector should not exceed the specified value. Strictly speaking, the current mechanical life span is a vague concept. Mechanical life should have a certain relationship with time. Obviously, 500 times have been used in 10 years, and 500 times in 1 year, the situation is different. It's just that there are no more economical and scientific methods to measure it.
The number of contact pairs can be selected according to the needs of the mechanical life of the Pogopin Pogo Pin connection of the circuit. At the same time, the size and total separation force of the Pogopin Pogo Pin connector are taken into account. The more contact pairs, the larger the size, the greater the total separation force. In some cases of high reliability and allowable volume, two pairs of contact pavilion can be used to improve the reliability of connection.
In the plug and socket of the POGOPIN Pin and socket, the pins (public contact) and the jack (mother contact) can generally be replaced and assembled. In actual use, you can choose according to the charging situation at both ends of the plug socket. If the socket needs to be charged frequently, you can choose the socket with a jack, because the charged contact of the socket with a jack is buried in the insulator. It is not easy for the human body to contact the charged contact, which is relatively safe.
The main consideration is the contact, impact, and collision of the Pogopin Pogo Pin connector to electrical continuity during the vibration, impact and collision under specified frequency and acceleration conditions. Under such dynamic stress conditions, the contact pair will open instantly. The prescribed transient time is generally 1μs, 10 μs, 100 μs, 1ms, and 10ms. It should be noted that how to judge the moment when the contact is paired. It is generally believed that when the voltage of the two ends of the (contact) at the closed contact is reduced by 50%of the power supply momentum, it can be determined that the closed contact pair (contact) fails. In other words, there are two conditions to determine whether an instantaneous interruption occurs: duration and voltage drop, and the two are indispensable.
