The output power interface 2 and the signal interface 3 are not contacted with each other and are arranged outside the plug frame body 1; the length of the signal interface 3 is shorter than the length of the output power interface 2 so that when the plug frame system is unplugged from the external system busbar, the signal interface 3 is disconnected from the external system busbar prior to the output power interface 2.
The output power interface 2 and the signal interface 3 may be integrated on one plug frame output interface 6 (as shown in fig. 2), or the output power interface 2 and the signal interface 3 may be installed on a plug frame system as independent interfaces.
The output power interface 2 is connected with the output end of the plug frame internal power supply 4 and is used for supplying power to an external system busbar.
The signal interface 3 is connected with the plug frame internal power supply 4, wherein the signal interface 3 is used for receiving a level signal generated when the plug frame system is plugged into and pulled out of the external system busbar, and the level signal is used for controlling the plug frame internal power supply 4 to be turned on and/or turned off, so as to control whether the plug frame system transmits power outwards. The level signal generated when the plug frame system is plugged with the external system busbar is generated by a signal bus.
The length of the signal interface 3 is shorter than that of the output power interface 2, the signal interface 3 is connected to the internal power supply 4 of the plug frame through the signal bus 5 in the plug frame body 1, the signal bus 5 can generate level change to obtain corresponding level signals when the plug frame system is plugged in and pulled out, the signal bus 5 transmits the level signals to the signal interface 3, and the signal interface 3 can control the internal power supply 4 of the plug frame to be turned on and off according to the level signals after receiving the level signals.

Further, when the plug frame power supply system is not plugged into the external system busbar, the signal interface 3 is in a floating state, and all the plug frame internal power supplies 4 are in a shutdown state. After the plug frame system is inserted into the system busbar, the signal interface 3 is short-circuited with the plug frame internal power supply 4 through the external system busbar, and the plug frame internal power supply 4 starts to be started normally, so that the influence on the external system busbar voltage when the output power interface 2 is contacted with the external system busbar can be avoided.
