When the current value is sensed below a certain range lower than the current value when the electric equipment is used and the value is maintained for a constant reference time, the standby Judging by the power state.

As such, when the electric device is determined to be in the standby power state, that is, when it is determined that the electric device is not actually used, the relay 130 is blocked by the above-described method, thereby supplying power to the electric device 20. It is controlled so that it is stopped and unnecessary power consumption is not generated.

Since the sensor 140 and the controller 150 are constituted by an electric electronic device or a module, a driving power for operation is required. The driving power is supplied by the driving power supply unit 160 of the present invention. The driving power supply unit 160 may be implemented as an SMPS. When the AC power supply of the main line 120 is supplied through the input line 161, the driving power supply unit 160 converts the supplied AC power into DC power to control the controller 150. ) To supply the driving power.

It may be configured to interlock with the first contact switch 171 connecting the line 122 and the input line 161.

When the support unit and the plurality of contact switches are provided as described above, power may be input to the driving power supply unit 160 only when all of the contact switches are electrically connected and turned on. It can be configured so that power is not inputted to. Through such a configuration, it is possible to further increase the operational reliability of the physical movement of the plug and thereby the operation of the electronic device.

In addition, after the support unit 180 having an inclined shape is provided on the side wall surface of the outlet groove 200, and the upper portion of the support unit 180 is hinged to the outlet groove 200, the torsion spring 86 is provided. By providing elastic resilience, the structure can be further simplified, and the internal space of the outlet can utilize the empty space on the side of the outlet as it is, allowing a more compact structure to be realized. Since the device according to the present invention can be utilized, it is possible to have versatility even when installing or replacing an outlet.

7 is a block diagram showing a configuration of an outlet device 100 for implementing a more preferred embodiment of the present invention.

The sensing unit 163 is configured to sense the current flowing in the input line 161, as described above to the support unit 180, the contact switch 170 to interlock according to the physical movement of the plug body (11) By using the configuration, it is possible to check whether the plug 10 is fitted and seated in the outlet groove 200 or whether the plug is separated from the outlet groove 200 through the current sensing of the sensing unit 163.

Meanwhile, the mode switch 190 of the present invention allows the outlet device 100 of the present invention to operate in a standby power cutoff mode and a boundary mode by inputting an external non-contact signal or a switch switching operation of a user. A change signal for the operating mode is input.

After the outlet device 100 of the present invention is converted to the boundary mode through the mode switch 190, the support unit 180 moves in the reverse direction by releasing the engagement of the plug body, and the contact switch is moved by the reverse movement. When it is off and no current is sensed in the sensing unit 163, the controller 150 controls the alarm unit 195 to be driven.

When the plug is disconnected in the boundary mode, the sensing unit 163, the controller 150, the alarm unit 195, and the like are operated so as to operate in the boundary mode by the mode switch. It is configured to be stored, and configured to drive the alarm unit 195, etc. for a predetermined time by the stored power.

The alarm unit 195 is not limited to the medium means as long as it is a means for transmitting information on plug detachment such as lighting of the visual medium (LED), driving of the acoustic medium (speaker).

In such a configuration, when the user accidentally detaches the plug, the user can implement a warning function such as reinducing the connection, and when the electric device is stolen by a third party, the plug connected to the electric device is detached from the outlet. Therefore, it becomes possible to perform a function as an alarm means for preventing theft.

In addition, the photosensitive sensor 193 is connected to the mode switch 190 to allow the mode switch 190 to automatically switch to the boundary mode at night time when no light is detected, and to turn on the daytime or indoor light where the light is detected again. It can be configured to automatically switch to standby power off mode in the environment, enabling a more user-oriented outlet device.

In addition, the alarm unit 195 is driven in the alert mode by connecting the communication module 197, which may be provided at a location physically separated from the outlet device, to the alarm unit 195 using power line communication built in the home. When the signal is input to the communication module 197 through power line communication, the communication module 197 stores information about location information and theft situation in a pre-stored external terminal (for example, a user's mobile phone or a competent government server, etc.). It can be configured to send alarm information.

The operation process of the above-described outlet device 100 according to the present invention is summarized as follows with reference to FIG. 8.

When the support means moves in one direction, the contact switch 170 is turned on, and AC power supplied from the main line 120 is supplied to the driving power supply unit 160 through the input line 161 (S130).

As described above, when AC power is supplied to the driving power supply unit 160, the driving power supply unit 160 converts the supplied AC power into DC power for driving the electronic device (S140) and supplies it to the control unit 150 of the present invention.

When driving power is supplied to the controller 150, the operation of the controller 150 is started (S160). When the sensor 140 measures a current value flowing in a periodic or real-time load line and outputs it to the controller 150 of the present invention, the controller 150 of the present invention determines whether the measured current value is in the standby power state to standby power. In the state, the relay 130 connecting the load line 110 and the main line 120 is controlled to be turned off.

On the other hand, if the plug is removed from the outlet groove 200 after being inserted (S185), the support unit 180 of the present invention is moved in the reverse direction (S187) is the connection of the contact switch 170 is released and thereby the contact switch 170 is in an off state.

The power supply to the driving power supply unit 160 is stopped by turning off the contact switch 170, so that the operation of the driving power supply unit 160 and the control unit 150 driven by the driving power supplied by the driving power supply unit 160 are also stopped. (S195, S197).
