Diodes in parallel connection, the output end of the switch power module and the anode of first diode connect, the yin of first diode
Pole is connect with power supply output pin, and the activation power input of the MCU module is connect with the cathode of the second diode, and described
The anode of two diodes is connect with power input pin.
It is connected according to diode forward, the working principle reversely ended, when the cable of conductive electrical communication interface insertion is that band is straight
When flowing power input, first diode is not switched on, and the conducting of the second diode pipe, DC supply input is to MCU module, to swash
MCU module living, MCU module turn on the switch the output end output DC power supply of power module.It is inserted into when conductive electrical communication interface
When cable is without DC supply input, first diode conducting, the second diode is not turned on, the output end of switch power module
DC power supply is exported to external equipment by conductive electrical communication interface.
The beneficial effects of the utility model are as follows：
The conductive electrical communication interface of the utility model is general-purpose interface, does not repartition voltage input interface and voltage output connects
Mouthful, due to the utility model Anti-misplug circuit, the network electric power interface of the utility model both can connect input power cable can also
To connect out-put supply cable, therefore solves previous deconcentrator there are wiring personnel by input power cable and out-put supply cable
It is reversed, the problem of causing deconcentrator can not work normally.Therefore it can be done using the deconcentrator of the utility model Anti-misplug circuit
It can be used to any one socket.The phenomenon that causing route to malfunction because of wrong plug line is also reduced in conference system installation, is reduced
Difficulty of construction.
