The present invention relates to a power supply cable for power supply / blocking of electronic products, and in particular, by turning off the main switch of the electronic product, it is possible to cut off the power applied to the electronic product, save energy consumption, and be easy to use. Not only is it convenient, but it also relates to a power cable for power supply / interception of a simple electronic structure.

BACKGROUND ART Electronic products widely used in the past have always been consumed with energy even when the main power switch is turned off because power is applied to the electronic products through a power cable.

However, even when the main power switch of the electronic product is turned off, the power is applied to the electronic product through the power cable, and there is a problem that energy is always consumed. In order to prevent the power from being applied through the cable, the main switch of the electronic product is usually turned off, and then the plug of the power cord should be unplugged from the outlet to prevent the energy consumption of the electronic product of the power supply. There are various problems such as the use of the product is very inconvenient.

Accordingly, the present invention has been made to solve the various problems described above, and an object of the present invention is to provide a power supply / blocking power cable for an electronic product that can cut off the power applied to the electronic product by turning off the power switch of the electronic product. It is.

Another object of the present invention is to provide a power cable for supplying / blocking electronic products that can save energy consumption.                         

Still another object of the present invention is to provide a power cable for power supply / interception of an electronic product which is easy and convenient to use.

Still another object of the present invention is to provide a power cable for supplying / blocking an electronic product having a simple structure.

In order to achieve the above object, the present invention provides a control unit for controlling the operation of an electronic product by receiving a full-wave rectifying means for receiving full-wave rectified AC power when switching on the main power switch and a full-wave rectified DC power in the full-wave rectifying means In the power supply / cut-off power cable of the electronic product provided, one side is connected to the AC power supply line (L1, L2) which is electrically connected to the positive and negative terminals of the main power switch, respectively, so that the power outlet A power supply plug having a pair of conductors attached to the other side of the AC power supply lines L1 and L2, and built in the power supply plug and excited when DC power is applied to the AC power supply lines L1 and L2. A movable contact (a) having both ends connected in series with one of the lines is in contact with the fixed contact (b) to apply AC power to the electronic product through the power supply conductor. At the same time, when the DC power is cut off, the movable contact (a) is separated from the fixed contact (b) to block the application of AC power through the power supply conductor, and the main power switch is interlocked with the relay And a relay switch for intermitting operation and non-operation, and a battery for supplying DC power to the relay so as to excite the relay when the relay switch is switched on.

Hereinafter, a power supply / blocking power cable for an electronic product according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram schematically showing a state in which power is cut off in a power supply / blocking power cable of an electronic product according to an embodiment of the present invention, and FIG. 2 schematically illustrates a state in which power is supplied in FIG. 1. The circuit diagram shown.

As shown in FIGS. 1 and 2, a power supply / blocking power cable of an electronic product according to an embodiment of the present invention includes full-wave rectifying means for receiving full-wave rectification by receiving AC power at the time of switching on the main power switch 12 ( 14) and a power cable for supplying / blocking the electronic product 10 having a control unit 16 for controlling the operation of the electronic product 10 by receiving the DC power rectified by the full-wave rectifying means 14; In the AC power supply line (L1, L2) and one side of the main power switch 12, the AC power supply line (L1, L2) which is electrically connected to each of the electrically connected (not shown) and the power outlet (or jack) so as to be plugged A power supply plug 20 having a pair of conductors 20a and 20b attached to the other side of the supply lines L1 and L2, and embedded in the power supply plug 20 and excited when the DC power is applied. Both ends of the AC power supply line (L1, L2) The movable contact (a) connected in series is in contact with the fixed contact (b) to apply AC power to the electronic product (10) through the power supply conductors (20a, 20b), and at the same time cut off DC power. And a relay 30 that separates the movable contact a from the stationary contact b to block the application of AC power through the power supply conductors 20a and 20b, and interlocks with the main power switch 12. And supplying DC power to the relay 30 to excite the operation and non-operation of the relay 30 and the relay 30 to excite the relay 30 when the relay switch 40 is switched on. The battery 50 is provided.

Next, the operation and effects of the power supply / blocking power cable of the electronic product according to the embodiment of the present invention configured as described above will be described.

First, the conductors 20a and 20b of the power supply plug 20 are plugged into a power outlet (or jack) not shown, and then the main power switch 12 is switched on. At the same time, the relay switch 40 ) Is switched on so that power is applied from the battery 50 to the relay coil 30a of the relay 30 through the relay switch 40 so that the relay coil 30a is excited. The movable contact a is in electrical contact with the stationary contact b.

Accordingly, the full-wave rectifying means of the electronic product 10 through the conductor (20a, 20b) of the power supply plug 20 and the AC power supply line (L1, L2) of the power supply plug 10 ( 14) and AC power is applied to the control unit 16, and the full-wave rectifying means 14 receives the AC power and supplies the DC power for controlling the electronic product 10 to the control unit 16.

When the main power switch 12 is switched off while the AC power is being supplied to the electronic product 10 as described above, the relay switch 40 is switched off at the same time so that the relay coil of the relay 30 ( Since no power is applied to 30a), the movable contact a is separated from the fixed contact b so that no AC power is applied to the full-wave rectifying means 14 and the control unit 16 of the electronic product 10 at all. Do not.

Therefore, the present invention can cut off the power applied to the electronic product 10 by turning off the main power switch 12, thereby saving energy consumption, and when the electronic product 10 is not used. Even if only the main power switch 12 of the electronic product 10 is turned off, the power supplied to the electronic product 10 is cut off, so that the computer is easy and convenient to use, and the structure is very simple.

In the above description, the specific embodiments have been shown and described, but the present invention is not limited thereto, for example, by those skilled in the art without departing from the concept of the present invention. Of course, the design can be changed in various ways.

As described above, according to the power supply / blocking power cable of the electronic product of the present invention, the power applied to the electronic product can be cut off by turning off the power switch of the electronic product, thereby saving energy consumption. Not only is it easy to use and convenient, but also has a very good effect such as simple structure.
