Description

Rotating type power outlet with easy state identification {Rotating type outlet capable of distinguishing ON / OFF state easily}

The present invention relates to an electrical outlet for reducing standby power, and relates to an electrical outlet that is easy to supply and cut off power and easily identify whether electricity is supplied without using a separate switching component.

Even when the power of the electric equipment connected to various outlets is turned off, the loss of standby power occurs because the connection to the electric equipment is maintained.

Statistically, to prevent standby power loss of 11% on average, the plug plugged into an electrical outlet must be unplugged, but it is troublesome for the user.

In order to solve this problem, in the case of an exposed type outlet such as a multi-tap, a method of using a power on / off switch and a display lamp for displaying the same is used for each plug insertion hole.

However, the on / off switch and the display lamp cause another waste of power and increase the number of parts and manufacturing labor. In addition, in the case of a small two-hole plug-in outlet standardized and built in various buildings, it is difficult to install a separate on / off switch due to space limitations, and there is no power on / off function. It can also be.

On the other hand, in the conventional outlet, the plug insertion port position is fixed vertically, horizontally or adjacent to 45 degrees in the main direction, so that plug insertion may be difficult.

In order to solve the above problems, various methods have been proposed, but the structure is complicated, the operation is cumbersome, and has not been well received due to the increase in manufacturing cost.

In particular, the Republic of Korea Patent Registration No. 10-0709505 (Publication No. 10-2007-0038678) and its preceding and subsequent information, but different from the present embodiment, although a number of outlets of the method focused on the rotation of the plug has been proposed, the operability and power It is difficult to identify whether electricity is being supplied, which causes a problem of poor practicality. That is, it is difficult to identify whether or not the current is not provided, and there is no clear function of marking of current.

SUMMARY OF THE INVENTION An object of the present invention is to provide an outlet having a power on / off function that efficiently reduces standby power from an outlet to an electrical product without removing a plug, while maintaining a conventional standard and minimizing parts and manufacturing labor. .

Another object of the present invention is to provide an electrical outlet that allows the user to clearly know the state of energization.

It is yet another object of the present invention to provide an electrical outlet which minimizes interference between adjacently inserted plugs.

In order to solve the above problem,

Remove the plug insertion module of the outlet but have a mark indicating whether the outlet is energized on the outside of the plug insertion hole, and the plug inserted into the outlet body to act as a handle of the rotary switch, so that the mark is displayed when rotating It was.

That is, the outlet lower body accommodating the power inlet and the plug contact terminal; on

A plug insertion unit having a pair of plug insertion holes and having an on / off mark of a power source at a predetermined position on the outside;

A plug outlet having an opening or a transparent window at an outer side thereof, and a rear surface thereof having an outlet cover having a rotation guide of the plug insertion unit at an outer side of the plug insertion hole.

When the plug is inserted into the outlet and rotated, the end of the plug rotates inside the outlet, causing contact or short-circuit with the plug contact terminal, and at the same time, a power on / off mark indicating whether electricity is supplied is displayed.

According to the invention,

Power can be controlled on / off by rotating the plug without any switching parts, preventing the loss of standby power,

Remote control of electrical products is possible, and various electrical safety accidents can be prevented.

In addition, it is easy to identify whether power is supplied or not.
