Description

Multi-plug receptacle for saving electricity}

The present invention relates to a power-saving multi-tap outlet, and more specifically, a power-saving and standby power cut-off part is provided at the power input end of the power strip, and the power-saving and standby power cut-off part can be easily attached or detached to the appearance of electrical and electronic products. The power saving switch is configured to be configured to allow the user to operate the power saving switch or to use the electrical / electronic products coupled to the main outlet, so that the power supply / blocking of the remaining electrical / electronic products coupled to the peripheral device is made. The present invention relates to a power-saving multi-tap outlet configured to prevent loss of power.

In general, multi-tap outlets that can use a plurality of home appliances and office equipment at the same time in a general home or office are used.

This conventional multi-tap outlet provides the convenience of plugging multiple electrical and electronic products into a single outlet, while the standby power is lost because the power cords of multiple electrical and electronic products are always plugged in even when not in use. There was a problem.

Standby power can save about 10% of the electricity consumption if the power cord is disconnected from the outlet when not actually using electrical and electronic products. Only rarely used to plug in the power cord.

Therefore, in order to reduce the inconvenience of plugging and unplugging electrical and electronic products into a multi-tap outlet, a power cut-off switch 7 capable of controlling power supply to an outlet equipped with a plurality of multi-taps protrudes from the upper surface of the multi-tap outlet. Products that can be used to prevent the loss of standby power by cutting off the power supplied to the electrical and electronic products by the operation of the actual use (shown in Figure 1), but also has a very low utilization rate of the conventional disadvantages as it is It was the same.

That is, even if the power strip switch 5 for preventing standby power loss is provided in the conventional multi-tap outlet main body 5 shown in FIG. 1, the multi-tap outlet main body 5 to which the power cord of the electrical and electronic product is connected is provided.

To turn on the computer main body, the power saving switch 30 is turned on and then turned on after the power is applied to the multi-tap outlet main body 5, and the power-on switch 30 is turned on. After a certain time has elapsed, when the power to the computer body is not turned on, the power saving mode and the standby power cut-off unit 40 automatically switch to the power saving mode, and the standby power is cut off. If you turn on the computer body after turning off / turning on), peripheral devices are also supplied with power.

That is, the power-saving outlet according to the second embodiment of the present invention provides an improved function than the first embodiment, and is used when an electric / electronic product composed of a set or several peripheral devices is plugged into one multi-tap outlet. By designating one outlet of the outlet as the main outlet (10), the power supply of the electrical and electronic products plugged into the peripheral device outlet (11) can be applied / blocked depending on whether the main outlet (10) is used. The standby power of peripheral devices is also cut off depending on whether it is possible to prevent enormous power waste due to standby power loss during power dead time and unmanned time, and to prevent various electric safety accidents such as fire by blocking leakage current.

The power-saving multi-outlet according to the present invention described above can be applied to conventional products and does not have much cost burden even in new production, thus inducing a lot of spread in real life and providing an opportunity to participate in preventing voluntary power loss of consumers. It is possible to easily cut off the main power supply of the multi-tap outlet main body 5 supplied to a plurality of electrical and electronic products, so that the utilization rate can be improved to reduce the problem that the expensive product is damaged or the performance is degraded during various electrical accidents. do.

In addition, when the power-saving switch 30 mounted on the outside of the electrical and electronic equipment or the exterior of the cabinet is manufactured in the shape of a number of characters, the power-saving switch 30 can be induced to further improve the use of the user. ) If you configure more than one, you can maximize the convenience of users because different people can be used in different places.

As described above, the power-saving multi-tap outlet according to the present invention is not only a conventional multi-tap outlet, but also newly developed, the application is simple and does not require excessive cost, and is easily accessible to the front or cabinet of the electric and electronic products. Since more than one power saving switch pulled out from the multi-tap outlet is attached, the power consumption of each product plugged into the multi-tap outlet can be prevented without the need to unplug the power cord. It provides an excellent effect to reduce the enormous economic loss.In particular, according to the use of the computer main body plugged into the main outlet, the power of the computer main body and its peripheral devices is automatically cut off, effectively preventing standby power consumption. Of course, by cutting off the leakage power during the dead time There is a beneficial effect in reducing the risk.
