Description

Plug and socket power plug {a combination concent and plug}

The present invention relates to a power supply plug for both outlets, and more particularly, having an outlet on the back of the power plug for supplying power to home appliances can be used by combining a plurality of outlet plugs in a single outlet It is to enable the function of the multi-tap.

In general, a plug provided to supply electric power to a home appliance includes a main body having a gripping portion for easy attachment and detachment from an outlet, and two grounds having a + pole and a-pole connected to the front surface with a part embedded in the main body. It consists of terminals.

And, the outlet is installed in a plurality of places of the predetermined position on the interior wall of the building, but the outlet is installed in one place is usually formed of two holes.

Therefore, the outlet installed on the wall has a limit in plugging in, and in general, the outlet formed on the wall is used by connecting a multi-tap having multiple outlets as necessary.

The multi-tap has a main body which is formed by a plurality of outlets that can be plugged in at the same time in a certain form, and the power supply to maintain the ready state so that power is supplied when the plug of the home appliance is plugged into the outlet of the main body portion It is composed of a plug to be supplied, and an electric wire which connects the plug and the main body to be used while freely moving the main body.

In this way, wall outlets can not be installed too many outlets in one place due to the installation area or aesthetics, so two outlets are usually installed in one place. When using a large number of electrical appliances in one place, plug in to supply power There are limitations to using power strips with multiple outlets.

And the plug is just for powering the home appliance.

Therefore, in order to use a plurality of electronic products in one place must be provided with a separate multi-tap, the plug is used by plugging in a number of wires are tangled with each other on the floor has a disadvantage that is not good.

In view of the above problems, the present invention allows a plurality of plugs to be grounded at a single outlet without a separate power strip, and is arranged so that the wires connecting the plugs and home appliances are not entangled.

It is an object of the present invention to provide a power outlet for both outlets that can be plugged into a plurality of plugs without a separate power strip in the wall outlet.

The present invention for effectively achieving the above object is a main body portion formed with a gripping portion to facilitate attachment and detachment from the outlet, and two ground terminals protruding to the front side divided into a + pole and a-pole in a state where a part is embedded A configured plug; The rear surface of the plug is provided with an outlet portion in which a connector of a conical tube shape connected to the ground terminal is embedded in the main body so that the ground terminal of the other plug can be inserted.

And, optionally, a fuse is embedded in the main body to protect the home appliances by cutting off the power when an overload occurs.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

1 and 2 show the shape of the power plug for the outlet of the present invention, Figure 3 is a partial cutaway side cross-sectional view showing the configuration of the present invention, the configuration is a grip portion 11 to be easily removable from the outlet (1) In the plug 10 consisting of a main body portion 10 is formed, and two ground terminals 21 protruded to the front side, divided into a + pole and a-pole in a state where a part is embedded in the main body 10 ; On the back side of the plug 20, an outlet part in which a ring-shaped connector 31 connected to the ground terminal 21 is embedded in the main body 10 so that the ground terminal 21 of the other plug 10 can be inserted ( 30) is provided.

And, optionally, the fuse 40 is embedded in the main body 10 to cut off the power when the overload occurs to protect the home appliances.

The main body portion 10 is provided with a gripping portion 11 to be easily attached and detached to the outlet (1), the groove portion 12 is formed on the upper and lower portions, the groove portion 12 is not shown in the figure However, in general, the ground piece 13 which is grounded to the earth terminal installed in the outlet (1) is embedded.

And, both sides of the main body portion 10 is provided with protruding pieces 14, and when connected to the outlet (1), serves as a guide to be more stably connected.

The ground terminal 21 is installed to protrude in the front of the main body portion 10 in a rod shape, and part of the ground terminal 21 is embedded in the main body 10 is connected to the + pole and-pole.

In the conventional plug 20 consisting of the main body 10 and the ground terminal 21 as described above, the present invention is characterized in that the outlet portion 30 is installed on the rear surface of the plug 10.

The outlet part 30 has two through holes 32 corresponding to the ground terminal 21 formed on the rear surface of the main body part 10, and is connected to the ground terminal 21 in a straight line with the through hole 32. The annular connector 31 is embedded in the main body 10.

Optionally, the fuse 40 may be embedded therein.

The fuse 40 is inserted into the front of the main body portion 10 so as to be replaced, one side is connected to the ground terminal 21, the other side is connected to the electric wire, and after installation, the stopper for separation and prevention and fixing ( 41) is fitted.

5 is a state diagram showing an embodiment of the present invention, when the power plug 100 of the present invention is pressed into the wall outlet (1) installed on the wall is supplied power to the home appliance, the ground terminal and the rear end Connected to the outlet portion 30 is provided with a connector 31 of the annular shape is connected to the main body portion 10 can plug in the other power outlet plug 100.

That is, the plug to which the present invention is applied can be used by connecting a plurality of outlets to one outlet 1.

In addition, the power plug 100 for both outlets may be used by embedding the fuse 40 in order to protect home appliances when an overload occurs.

That is, as shown in FIG. 3, if an overcurrent flows by installing a fuse 40 between the ground terminal 21 and a wire connecting the home appliance, the fuse may be cut off to cut off the power supply to the home appliance due to the overcurrent. Prevent damage.

In addition, the fuse 40 is preferably installed in a retractable type so that it can be easily replaced, it is closed with a stopper 41 to fix it.

In addition, since the grounding terminal 21 of the power plug 100 for an outlet and the connection port 31 of the outlet portion 30 are integrally connected, the power supply only cuts power to the corresponding home appliance even when the fuse 40 is blown. The other outlet and power plug 100 is connected to continue to supply power.

As described above, according to the present invention, the power plug for both outlets is provided with a ground terminal 21 on the front side like a general plug, and has an outlet portion 30 to which another plug 10 can be inserted on the back side thereof. Without this, a plurality of plugs 10 can be connected to one outlet 1 installed on the wall.

Therefore, it is possible to obtain economic benefits without the need for a separate multi-tap such as a connection device, and the plugs are arranged in a line, and the wiring is easy to align by plugging.
