In general, when not using an electronic device when using an outlet or a power strip in a home or an office, the power plug must be completely disconnected from the outlet or power strip, and this may occur even when the power switch of the electronic device is turned off. This is because a small power of approximately 5W per hour is applied to the corresponding electric appliance through the plug of the electronic device through the plug of the electronic device, which causes a large power loss.

As such, in order to prevent unnecessary loss of standby power, conventionally, an on / off switch for shutting off the main power is separately provided at an outlet or a power strip to which the power plug of the electronic device is connected. By turning off the outlet or multi-tap, the standby power can be cut off. In another method, electronic devices such as a current measuring device, an electronic control device, and a motion detection sensor device are mounted on a power strip or the like so that the on / off switch directly attached to the power strip is not operated manually, but rather the electronic device is automatically turned on.

The cutoff switch 41 is installed to penetrate the cutoff switch guide hole 83 formed inside the fixing bracket 80, and supports the elastic member 90 on the upper jaw of the cutoff switch guide hole 83. The upper surface of the engaging jaw 42 of the blocking switch 41 receives the receiving, and the lower jaw is installed so that the upper surface of the other engaging jaw 42 of the blocking switch 41.

The blocking locking piece 46 is provided with a blocking locking jaw 47 so as to be fitted into the locking groove 43 on one side thereof, forming a cylindrical body on the other side thereof, and having a predetermined interval in the longitudinal direction on the outer circumferential surface thereof. A locking jaw 48 is formed, and the elastic member 90 may be installed as an outer circumferential surface between the pair of locking jaws 48. The blocking engagement piece 46 is installed to penetrate the blocking engagement piece guide hole 82 formed hollow inside the fixing bracket 80, and an elastic member 90 is disposed at one side jaw of the blocking engagement piece guide hole 82. It is installed so that one locking jaw 48 of the blocking locking piece 46 is supported by the support, and the other locking jaw (48) of the blocking locking piece 46 is caught on the other side jaw, the other locking jaw 48 may be formed at the other end of the blocking engaging piece 46 in the shape of a disc.

When the user turns on the electronic device, since a certain amount of current flows through the wire provided with the current sensor unit 50, the induction current generation unit 62 does not generate an induction current, so the cutoff switch 41 is blocked. It is in the On position with the hooked in (47) and power is continuously supplied to the electronics.

In addition, when the user turns off the power of the electronic device, as shown in FIGS. 5B to 5D, the amount of current flowing through the wire in which the current sensor unit 50 is installed is momentarily reduced. It is transmitted to the control unit 60 through the current sensor unit 50 and the induced current is generated in the induction current generating unit 62 according to the change in the amount of current, and the generated induction current is amplified by the current amplifying unit 63 and the electromagnet unit ( 64, the electromagnet portion 64 is an elastic force provided in the blocking piece guide hole 82 to block the blocking piece 46 adjacent to the electromagnet portion 64 by the magnetic force generated by the amplification of the induced current current The blocking latching jaw 47 is pulled out of the catching groove 43 of the blocking switch 41 by pulling with an attractive force greater than the elastic force of the member 90. Accordingly, the cutoff switch 41 moves upward by the restoring force of the elastic member 90 provided in the cutoff switch guide hole 82, and the contacts 22 and 45 of the rod plate 21 and the driving plate 44 are moved upward. ) Is short-circuited, thereby cutting off the power supply from the power supply unit 20 to the power connection unit 30, thereby preventing the consumption of standby power.

In order to reconnect, the user pushes the upper portion of the cutoff switch 41 protruding from the cutoff hole 72 of the outlet cover part 70 to the locking groove 43 formed at the bottom of the cutoff switch 41. The blocking latching jaw 47 is caught and fixed, and the contact 45 of the driving plate 44 and the contact 22 of the road plate 21 are connected to supply power to the power supply unit 20. It is supplied to the electronic device through) to maintain the On (On) state.

As shown in FIG. 1, in the case of a two-hole outlet in which the connection sockets 32 of the power connection unit 30 are formed in pairs at the upper and lower sides, when any one of the electronic devices connected to the upper and lower sockets is turned off. Since the power of electronic devices connected to other sockets is also turned off, in this case, the power of the computer body is turned off at the same time by connecting the power of the computer body to one place and connecting the accessories to other places to turn off the power of the computer body. You can also get the effect. Therefore, with the position where the electronic sensor unit 50 is installed, up and down by the selective connection of the connection socket 32 of the power connection unit 30 connected to the drive plate 44 of the power cut-off unit 40. The standby power of the electronic device connected to the connection socket 32 may be selectively cut off.

With the above configuration, when the power of the electronic device is turned off, the current flowing from the main power source to the electronic device is automatically cut off without the need to unplug the power plug of the electronic device, thereby preventing the consumption of standby power. Will be.
