Anti-sparking power type communication electrical connector

Abstract

The invention proposes a communication electric plug connection part of an ignition power prevention type, and the electric plug connection part comprises a power terminal and a power ground terminal, and a power line and a power ground line, which are respectively connected with the power terminal and the power ground terminal. The electric plug connection part comprises a signal terminal and a signal ground terminal, and a signal line and a signal ground line, which are respectively connected with the signal terminal and the signal ground terminal. An energy storage capacitor is electrically connected between the power line and the power ground line, and an inhibition ignition resistor is electrically connected between the signal ground line and the power ground line. During the paired plug connection of the plug connection part, the electric connection between the signal ground terminals is ahead of the electric connection between the power terminals, and the electric connection between the power terminals is ahead of the electric connection between the power ground terminals and the electrical connection between the signal terminals. Therefore, after the electric connection between the signal terminals and the electrical connection between the power terminals, the inhibition ignition resistor and the energy storage capacitor form a loop, so as to inhibit the energy storage capacitor from instantly releasing a big current. The electric plug connection part can avoid the ignition phenomenon, thereby protecting the electric plug connection part and the communication circuit from being damaged.

Description

technical field [0001] The invention relates to the technical field of electrical plug connectors, in particular to an anti-sparking power type communication electrical connector. Background technique [0002] Plugs and sockets are generally used in pairs, and there are usually plugs and sockets for power connections, and plugs and sockets for communication connections. The current anti-sparking power socket or plug only relies on the structure to realize the function of avoiding sparking linearity. Usually, a limit switch is arranged in the plug core. When the plug is inserted into the upper section of the socket, the opening is in the off state, and the load There will be no ignition when there is no current. Only when the plug is inserted in place, the ejector rod in the socket can press the switch handle of the limit switch to turn on the switch and power on, so as to avoid ignition when the plug is inserted; the opposite is true when the plug is pulled out. The ejector...

Problems solved by technology

However, the long-term operation of the mechanical structure will make the structure loose and unstable, and increase the internal accommodation space of the plug and socket. Moreover, it does not have a communication function and cannot realize data communication.

[0003] Ordinary communication plugs or sockets can only realize small signal communication functions, and are difficult to be compatible with high-current connection terminals, especially difficult to be compatible with power supply connection terminals for high-power loads. And the plug and socket used as a communication connection are put together, and the usual practice is to plug in and out with a hard connection

All high-power loads must have large-capacity energy storage freewheeling capacitors and corresponding ignition capacitors. Hard connection plugging cannot avoid the discharge of energy storage capacitors in the circuit and sparks during the plugging process, and there is no guarantee. The correct power-on sequence is very easy to damage the communication interface, or destroy the integrity of the communication signal

[0004] In addition, the sudden change of high-power load current that occurs during power-on or power-off or other situations will have an impact on the signal communication of the communication terminals, causing crosstalk between each other, the signal cannot be output normally or completely, and the electrical performance is also affected. unstable

Therefore, at present, the plugs and sockets used as power connections and the plugs and sockets used as communication connections are usually arranged separately, which brings inconvenience to plugging and the problems of many and messy plugging parts.
