The principle of operation of the present invention will now be described as follows: the power supply plug of each device of the communication system is spliced with each jack component 303 on the PDU power strip 3, power is supplied to each device of the communication system through the main power supply 1 and the standby uninterruptible power supply 2, the power is reasonably distributed to each communication device through the PDU power strip 3, and when the main power supply 1 is disconnected due to power failure, the standby uninterruptible power supply 2 can automatically disconnect the connection with the main power supply 1 and power is supplied by using a storage battery of the standby uninterruptible power supply 2;
when a plug of the communication equipment is inserted into the corresponding jack assembly 303, the plug firstly presses the pressing plate 153, the pressing plate 153 drives the insulating inserting rod 152 to move so as to drive the second conductive block 156 to move, after the plug is inserted into place, the pressing plate 153 is clamped into the groove 154, at the moment, the first conductive block 155 and the second conductive block 156 are contacted, so that a connecting loop among the first normally closed electromagnetic valve 14, the first conductive block 155, the second conductive block 156 and the controller 4 can be connected, at the moment, the first normally closed electromagnetic valve 14 is electrified and opened, the small air pump 6 starts to be electrified and works, air conveyed by the small air pump 6 enters the corresponding air cavity 9 through the air supply pipe 8 at the opening position of the air conveying pipe 7 and the first normally closed electromagnetic valve 14, then is conveyed to the magnetism isolating hollow insulating block 11 through the air outlet pipe 10 at the position, and finally is discharged through the air outlet hole 13;
under the action of the air flow, the heat generated by the jack assembly 303 during power supply can be quickly taken away and can be contacted with the thermistor 12 at the jack assembly 303 when being discharged through the air outlet pipe 10, the resistance value of the thermistor 12 is reduced along with the temperature rise, the heat generated in unit time of the jack assembly 303 during normal power supply has little difference, the air flow flowing through the air cavity 9 can meet the heat dissipation requirement of the jack assembly 303, if the phenomena such as abnormal power supply current occur, the temperature at the jack assembly 303 can be quickly raised, at the moment, the air flow flowing through the air cavity 9 can drive the raised heat to be contacted with the thermistor 12, thereby greatly reducing the resistance value of the thermistor 12, at the moment, the current flowing into the corresponding first electromagnetic switch 161 is quickly increased, thereby enabling the moving contact of the first electromagnetic switch 161 to be sucked, at this time, the connection loop between the first normally closed electromagnetic valve 14 and the controller 4 can be disconnected, and the connection loop between the second normally closed electromagnetic valve 164 and the controller 4 can be connected, at this time, air entering the inside of the magnetism isolating hollow insulating block 11 can enter the inside of the cavity 162 through the round hole 163, if the jack component 303 continuously generates abnormal temperature and keeps for 5 seconds, at this time, because the second normally closed electromagnetic valve 164 is continuously opened, air entering the inside of the cavity 162 can be rapidly increased, at this time, air cannot be timely discharged through the micro ventilation hole 165, so that air pressure inside the cavity 162 can be rapidly increased, thereby pushing the insulating piston 19 to move until the first copper block 21 on the insulating piston 19 contacts with the second copper block 22, at this time, the moving contact of the second electromagnetic switch 166 is magnetically closed, and after the controller 4 receives the electric signal of the second electromagnetic switch 166, the connection circuit between the jack assembly 303 and the communication device is rapidly disconnected, and after the connection circuit is disconnected, a person needs to manually press the reset switch on the controller 4 to recover the normal power supply of the jack assembly 303, if the jack assembly 303 is only abnormally heated due to accidental overload of current, the first electromagnetic switch 161 is disconnected again due to rapid recovery of the temperature of the thermistor 12 after being closed, at this time, the air entering the cavity 162 through the round hole 163 is limited, and the redundant air is discharged through the micro ventilation hole 165, so that the second electromagnetic switch 166 is not disconnected, and the condition that the communication device is powered off due to false triggering is prevented;
when the plug of the communication device is inserted into the jack assembly 303, the first conductive block 155 and the second conductive block 156 on the sides are contacted, at this time, the corresponding LED lamp beads 25 are electrified synchronously, the light intensity emitted by the corresponding LED lamp beads 25 is in direct proportion to the power supply intensity of the corresponding jack assembly 303, after the LED lamp beads 25 are lightened, the photoresistor 26 can reduce the resistance value of the photoresistor due to the increase of the light intensity, at this time, the frequency converter 27 can automatically adjust the conveying power of the small air pump 6 according to the current passing through the connecting loop of the photoresistor 26, so that the heat dissipation air quantity conveyed by the small air pump 6 can meet the heat dissipation requirement of the jack assembly 303 without continuously keeping the small air pump 6 in full load operation, and further reducing the energy consumption;
when the plug that needs to be connected with the jack assembly 303 is pulled out, a person presses the push switch 28, at this time, the moving contact of the push switch 28 is closed, so that a connection loop between the first normally closed electromagnetic valve 14 and the controller 4 can be disconnected, at this time, the first normally closed electromagnetic valve 14 is restored to a normally closed state, and when air entering the air cavity 9 cannot be discharged through the air outlet 13, the air pressure inside the air cavity 9 can be rapidly increased, under the action of the air pressure, the conical plugging block 173 can be pushed out outwards, and along with the increase of the air pressure, the displacement of the conical plugging block 173 is larger, at this time, the distance that the conical plugging block 173 is pushed out outwards through the push rod 174 is larger, so that the person can be assisted to pull out the plug of the communication device, and the convenience of use is improved.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
