Thus, a user only places the plugs -of important electrical products in the connection sockets C1 and C2 belonging to a group with the highest priority and places the plugs of electrical products that are not used frequently or that are less important in the connection sockets C6 and C5 that have the lowest priority. Constructing the main body (2) of the multiple type power strip, when the overload is generated, the electrical energy is continuously supplied to an electrical product in which the overload is avoided and the electrical energy has to be supplied first. Meanwhile, the remote control (4) illustrated in Fig. 1, illustrated in Fig. 4, includes a plug-in controller button unit (40) having as many control buttons of outlet as the number of connection sockets (eg, 6) provided in the main body (2) in which the same color indicators as the color indicators such as red R, orange O, yellow Y, blue BL , green G, and black BK, painted on the respective connection sockets C1 to C6 of the main body 4 of the multiple type strip are painted on the outer circumferences of the six buttons. The buttons, for example, are transparent or semitransparent covers, and light emitting lamps LD1 to LD6 corresponding to the buttons are installed in a housing of the remote control (4) under the buttons.

The keyboard (36) includes the plug-in control button unit (40), the mode switch (42), the light button (44), and the adjustment button (46) which are described with reference to figure 4, and supplying key data corresponding to the controller unit of the remote control (30) when the user presses a key. The light emitting lamp (38) includes three light-emitting lamps of color LD 1 to LD3 installed on the bottom sides of the outlet control buttons in an amount equal to the number of the connection sockets, and turn on or off under the control of the controller unit of the remote control (30). The main body (2) of the multiple type power strip in Figure 1 includes a main body electrical circuit as illustrated in Figure 2. With reference to Figure 2, the main body electrical circuit includes a 1 0 controller, a DC power source (1 2), a transmitter unit and a radio frequency (RF) receiver unit (14), a memory (1 6), a CT current transformer, a current detector (1 8) , an operating light unit (20) having a plurality of operating lights LP 1 through LP6, and a switching unit (24).

The switching unit (24) includes a plurality of relay switches RL1 through RL6 corresponding to and connected to the many connection receptacles C1 through C6, and relay handling units RD1 through RD6. The relay handler units RD1 through RD6 switch the switches RL 1 to RL6 under the controller (10) to selectively form commercial alternating current (AC) power supply paths to the connection sockets C1 to C6. The CT wraps the power cable (22) in the main body (2) of the multiple-type power strip, converts a generated magnetic field when the electric current flows through the power cable (22) in the electric current, and produces the converted current to the current detector (1 8), and then the current detector (1 8) supplies voltage corresponding to the current converted to the controller (10). Thus, the controller (10) can verify the state of charge of the electric power supplied to various electrical products whose plugs are inserted into the connected outlets C1 to C6 of the main body (2) of the multiple-type terminal strip based on the voltage supplied from the CT and the current detector (1 8). The RF transmitter and a receiver unit (1 4) is a block to transmit and receive a radio frequency (RF) signal to and from the external remote control (4) in the commercial frequency broadband, the power source of CC (1 2) converts commercial AC power into DC current and supplies DC power converted to the controller (10) and other circuits. The many operating modes LP 1 to LP 6 of the operating light unit (20) are installed on the upper sides of the connection sockets C1 to C6 of the main body (2) as illustrated in FIG. 1 and are switched on selectively by the controller (1 0). In the memory (1 6) in figure 2, an operation program is mapped, the data referring to the priority of power supply and data such as an overload threshold are stored, and various data are stored and read under the control of the controller (1 0). The controller (10) switches the relay switches RL 1 to RL6 of the switching unit (24) based on a remote controller signal from the remote control (4) supplied through the RF transmitter and a receiver unit (1). 4), and switches the relay switches RL1 to RL6 of the switching unit (24) based on the predetermined priority of supplying power when the voltage corresponding to the state of charge supplied from the current detector (18) exceeds a threshold Default overload The controller (10) controls some of the operating lights LP1 through LP6, corresponding to the switches that are going to supply power at the moment, so that they are turned on, and transmits the status of the current current switch to the remote control (4) in response to the request for the status of the power switch coming from the remote control (4). A reference number P in figure 2 is assigned to a Plug. Figure 5 is a flow diagram illustrating the control executed by the controller (10) of the main body (2) of the multiple type strip in Figure 2. In the following, the modality of the present invention will be described in detail with reference to the accompanying drawings as follows. The user checks the color indicators of the main body (2), inserts the plug of the important electrical product that has a higher priority into the connection socket C1 or C2, and inserts the plug of the electrical product that is not used frequently or is less I mportant in the C6 or C5 connection socket, which have the lowest priority. All the connection sockets C1 to C6 of the main body (2) are controlled for the supply of commercial energy to the electrical products whose plugs are inserted in the connection sockets C1 to C6, but can be controlled individually for the supply of the commercial energy when the switches are controlled remotely by the remote control (4) or overload is detected. The controller (1 0) of the main body (2) normally controls the corresponding relay switches RL 1 through RL6 of the switching unit (24) to be switched on, and simultaneously controls all the operating lights 20 of the light unit of operation (20) to be lit in green. By doing this, commercial energy is supplied to the electrical products whose plugs are inserted in the connection receptacles C1 to C6, and the operating lights 20 placed respectively in the connection receptacles C1 to C6 turn green. However, the light emitting lamps LD 1 to LD 6, which are installed on the lower sides of the respective buttons of the outlet control button unit (40) corresponding respectively to the connection sockets C1 to C6 of the remote control (4), turn off initially, and turn on or off according to the response to the request to verify the states of the switches coming from the primary body (2) after the user presses the light button (44) to make the request In other words, when the user presses the luminous button (44) to request the status of the switches, the controller unit of the remote control (30) transmits the status of the switches through the RF transmitter and a receiver unit (32) on the wireless line and the controller (10), which has received the signal to request the status of the switches through the RF transmitter and a receiver unit (1 4) of the main body of the multiple-type terminal board, read the states of the switches stored in the memory (1 6) and transmit a response signal for the request to verify the states of the switches to the remote control (4) by the wireless line (operations 1 04 and 1 06 in figure 5). By doing this, the controller unit of the remote control (30) controls the light emitting lamps LD 1 to LD6 of the light emitting lamp unit (38) to be switched on or off based on the response signal to the request to verify the state of the switches. The green illumination of the light emitting lamp unit (38) of the remote control (30) goes off when a predetermined time (for example, approximately 30 seconds) elapses, so that the battery consumption of the battery can be reduced. remote control (4) The user observes the on and off states of the respective buttons of the outlet control button unit to obtain the current states of the connection receptacles C1 to C6 of the main body of the multiple type power strip and for individually control the desired connection outlets for the supply of electrical power. Particularly, since the color indicators are identical to the color indicators in the upper circumferences of the respective connection sockets C1 to C6 of the main body (2), the user can easily find the desired connection sockets for the power supply electricity. When the user presses one of the buttons between the buttons of the outlet control button unit (40) to be individually controlled, the remote control controller unit (30) of the remote control (4) transmits a remote controller switch that corresponds to press the button through the RF transmitter and a receiving unit (32) and the controller (1 0) of the main body (2) receives it to control the corresponding relay switch of the switching unit (24) and to turn on or off the corresponding operating light of the operation light unit (20) (operations 1 00 and 1 02 in figure 2). Moreover, a result of controlling the relay switches is transmitted to the remote control (4) by the wireless line in such a way that the remote control controller unit (30) again turns on or off a light emitting lamp corresponding to the power outlet of the remote control. connection, which is individually controlled for the supply of electric power, green. When doing this, the button pressed by the user is indicated directly by the lighting in green or the shutdown. Due to the control mentioned above, the user can individually control the connecting sockets of the main body (2) of the multiple type power strip remotely and can monitor the current states of the power outlets for individually supplying electrical power if it is necessary. Meanwhile, the controller (1 0) of the main body (2) periodically detects the state of charge of energy applied to the main body (2) of the multiple type strip through the current detector (1 8) and verifies whether the current load is greater than a predetermined overload threshold when stored in memory or not (operations 1 08 and 1 1 0 in figure 5). The threshold of Default overload can be set from 80% to 1 30% of an estimated load. In determining the operation (1 1 0) in Fig. 5, if the current load is greater than the predetermined overload threshold, the controller (10) shuts off the relay switches of the switching unit (24) in the order reverse the priority based on the priority and check the current load (operations 1 1 2 and 1 1 4 in figure 5). Additionally, the result of turning off the relay switches is transmitted to the remote control (4) by the wireless line (operation 1 1 2 in figure 5) in such a way that the remote control controller unit (30) controls the emitting lamps of light (for example, the light emitting lamps LD6 and LD5) corresponding to the connection sockets turned off so that they turn off after a predetermined time has elapsed. Since electrical product plugs that are not important or are not used frequently are inserted in advance in some of the connection receptacles C 1 to C6 of the main body (2) of the multiple-type power strip that has lower priority, for example, the connection sockets C6 and C5, there is no fear of generating a critical problem even when power is not supplied. Due to the control in the present invention as described above, when the overload is generated in the main body of the multiple type power strip, overloading and overloading can be prevented.

Electric power can be continuously supplied to the electrical product that has to be fed with electric power with a high degree of priority. If, despite the fact that the switches of the switching unit (24) are switched off and the switches belonging to the highest priority group are switched on based on the priority, the overload generation state continues, the controller (1 0 ) of the main body (2) of the multi-type power strip does not turn off the corresponding switches that have the highest priority group directly, but instead activates a delay timer for a few tenths of seconds or a few tenths of a minute and transmits a flat switch-off notification signal of the switch to the controller unit of the remote control (30) by the wireless line (operation 1 1 6 in figure 5). In doing so, the remote control controlling unit (30) controls the light emitting lamps LD2 and LD 1 corresponding to the connection sockets belonging to the group of highest priority so that they turn off and flash yellow. As the light emitting lamps of the respective buttons corresponding to the connection sockets in the highest priority group flash yellow, the user can manage the movement of the sockets of the corresponding electrical products towards other connection sockets. When the delay timer is stopped (operation 1 1 8 in figure 5), the main body controller (2) of the power strip Multiple type controls the switches that have the lowest priority among the switches belonging to the group of highest priority so that they turn off and transmits the result of turning off the relay switches to the remote control (4) on the wireless line (operation 1 20 in figure 5). In doing so, the remote control controlling unit (30) controls the light emitting lamps (for example, the LD2 and LDI light emitting lamps) flashing yellow and corresponding to the switched off sockets so that they turn off after that flash in red for a previously determined time. Meanwhile, the remote control (4) can be used as a remote control for a television in addition to the function of individually controlling the connecting sockets of the main body (2) of the multiple-type power strip for the supply of electrical energy. In other words, since the mode switch (42) is provided on the keyboard (36) of the remote control 36, the user switches the mode switch (42) from "REGLETA" to "TV" in such a way that the unit controller of the remote control (30) switches to television mode. In the television mode, the user presses the adjustment button (46) up, down, right and left so that the channels and the volume of the television can be adjusted. In a more detailed description, when the user presses the adjustment button (46) upwards, downwards, to the right and to the left in television mode, the keyboard (36) applies key data corresponding to the pressure of the adjustment knob (46) to the remote control controller unit (30) and the remote control controller unit (30) transmits an infrared signal corresponding to television through the infrared transmitter (34).

However, the light emitting lamps LD1 to LD6, which are installed on the bottom sides of the respective buttons of the outlet control button unit (240) corresponding respectively to the main bodies of intermediate receptacles (202k) of the control remote (204), are initially turned off, and turn on or off according to the response for the request to verify the states of the switches coming from the main bodies of intermediate receptacles (202k) after the user presses the light button (244) to make the request. In other words, when the user presses the light button (244) to request the status of the switches, the remote control controller unit (230) reads the allocation index codes stored in the memory to generate the request signals of the user. verification of the states of the switches that are going to be transmitted to the respective main bodies of intermediate receptacles (202k) (operations 300 and 302 in FIG. 10), and thereafter transmits the request signals for verification of the states of the switches to the respective main bodies of intermediate receptacles (202k) through the transmitter RF and a receiving unit (232) on the wireless line (operation 304 in FIG. 10). In doing so, the controllers (21 0) of the respective primary intermediate tap-off bodies (202k) receive the request signals to verify the states of the switches through the RF transmitter and the receiving units 21 4 (operation 400 in Figure 1 1). Each of the controllers (21 0) determines whether the received request signal is the assignment index code assigned to itself, and if this is correct, the controller (21 0) reads the state of the switch stored in the memory (21 0). 21 8) and transmits a response signal to the request to verify the state of the switch to the remote control (204) by the wireless line (operations 402 and 404 in figure 11). When the response signals for requests to verify the states of the switches are received from the main bodies of intermediate receptacles (202k) (operation 306 in FIG. 10), the remote control controller unit (230) of the remote control (204) controls the light emitting lamps LD 1 through LD6 of the light emitting lamp unit unit (238) to be switched on or off based on the received response signals (operation 308 in FIG. 10). At this time, given that the green light state of the light emitting lamp unit (238) of the remote control (230) is controlled to turn off after a predetermined time has elapsed (eg, approximately 30 seconds) by the controlling unit of the remote control (230), the battery of the remote control (204) can be reduced. The user observes the on or off states of the respective buttons of the outlet control button unit (240) to obtain the current states of the respective main receptacle main bodies (202k) and to individually control the main body of the intermediate receptacle ( 202k) desired for the electric power supply. Particularly, since the color indicators are identical to the color indicators in the upper circumferences of the respective main bodies of intermediate receptacles (202k), the user can easily find the desired intermediate receptacle body (202k) for the power supply. When the user presses one of the buttons of the outlet control button unit (240) corresponding to the desired intermediate receptacle main body (202k) to be individually controlled, the remote control controller unit (230) of the remote control (204) reads the corresponding memory allocation index code (239) and generates a remote switch controlling signal corresponding to the code of Assigned assignment index for transmitting the remote controller signal of the switch through the RF transmitter and a receiver unit (232) on the wireless line (operations 31 0 and 31 2 in FIG. 10). The controller (21 0) of the corresponding intermediate receptacle main body (202k) receives the remote control signal of the switch to control the relay switches RL of the switching unit (21 6) that are to be switched and to turn the light on or off of operation (220k) (operations 406 and 408 in figure 11). Moreover, the controller (210) transmits the result of controlling the relay switches RL as an RF response to the remote control (204) by the wireless line (operation in figure 11). The control unit of the remote control (230) of the remote control (204) that has received the RF response controls a light emitting lamp corresponding to the intermediate receptacle main body (202k) that is newly controlled for the power supply of the power source. remotely, between the light emitting lamps LP 1 to LP6 of the light emitting lamp unit (238) so that they are lit in green (operations 31 4 and 31 6 in figure 1 0). When doing this, the green illumination or the shutdown of the button pressed by the user is indicated directly. Due to the aforementioned operations, the user can individually control the main bodies of intermediate receptacles (202k) for the electric power supply remotely and can monitor the main bodies of intermediate receptacles (202k) according to the current states of power supply to the main bodies of intermediate receptacles (202k). Meanwhile, the remote control (204) can be used as a remote control for a television in addition to the function of remotely and individually control the electrical energy to be supplied to the main bodies of intermediate receptacles (202k). In other words, since the mode switch (242) is provided on the keyboard (236) of the remote control (204), the user switches the mode switch (242) from "REGLETA" to "TV" in such a way that the controller unit of the remote control (230) switches to television mode. In television mode, the user presses the adjustment button (246) up, down, right and left so that the channels and the volume of the television can be adjusted. In a more detailed description, when the user presses the adjustment button (246) up, down, right and left in television mode, the keyboard (236) applies key data corresponding to the button pressure. of adjustment (246) to the remote control controller unit (230) and the remote control controller unit (230) detects the key data and transmits an infrared signal corresponding to the key data to the television via the light transmitter infrared (234) (operations 31 8 and 320 in Figure 1 0). While short-range communication by RF between the main bodies (2) and (202k) of the remote control strip and control (4) and (204) is described by RF communication, it will be evident to those trained in the technique that can be used Bluetooth, Wi Fi, and the like as short-range RF communication. Industrial Applicability The present invention can be applied to plugs of various electrical products.
