Description

Multi-tap for outlet cover with plug {MULTI-TAP FOR WALL SOCKET COVER WITH PLUG}

The present invention relates to a power strip for an outlet cover equipped with a plug, and more particularly, to a power strip for an outlet cover equipped with a plug, which prevents the inside of the outlet from being exposed to the outside and minimizes the height of coupling with the outlet. will be.

In general, an electrical outlet has a socket, and when using an electrical appliance, a plug is inserted into the socket.

1 is an exemplary view showing a state in which a plug is coupled to a conventional outlet, and is an exemplary view of a coupled state of an outlet 10 and a plug 20 viewed from the side.

The plug 20 is provided with a gripping portion 21 that the user can grip by hand, and the user inserts the plug 20 into the outlet 10 or inserts the plug 20 connected to the outlet 10 into the outlet. It can be easily separated from (10).

In this way, in a plug-in state in which the plug 20 is connected to the outlet 10, the gripping portion 21 protrudes to the outside of the outlet 10, so the user holds the gripping portion 21. In the plug 20 coupled to the outlet 10 can be easily separated.

For example, when a chest of drawers or a cupboard is placed on the wall 1 on which the outlet 10 is placed, it is difficult to use the outlet 10. 10) Power is supplied to electronic products placed around it.

However, when the power strip 30 is coupled to the outlet 10, since the plug 20 provided on the power strip 30 must be coupled, the corresponding plug 20 protrudes out of the outlet 10. There is a problem. In this case, a wardrobe or a cupboard disposed at the outlet 10 should be spaced apart from the wall 1 by a certain distance or more. That is, since the corresponding furniture product cannot be attached close to the wall 1, there is a problem of poor space utilization and a poor arrangement of furniture. In addition, it is difficult to disconnect the plug 20 inserted into the corresponding outlet 10.

Even if an electronic product such as a refrigerator is disposed on the wall 1 where the outlet 10 is disposed, the same problem as described above occurs.

Therefore, various researches and developments are required for a structure of an outlet coupling device designed to minimize the thickness protruding from the wall when coupling the plug to the outlet.
