Background Art [0002] Earth Connection Equipment for Plug Socket [0003]

The present invention relates to a ground wire connection structure of a recessed electric socket,

In connecting the ground wire to the metal band to which the receptacle ground terminal is connected,

It is possible to connect the ground wire to the metal band more easily and quickly,

And more particularly, to a ground wire connection structure of a recessed type electrical outlet so as to further improve workability due to connection of a ground wire.

Generally, a built-in type electrical outlet which is embedded in a wall surface of a building is provided with a metal band for fixing the outlet body to the outlet box, and the ground terminal is connected to the metal band, .

A known technique for connecting such a ground wire will be described.

In the case of the "grounding wire connection structure of an electrical outlet" of Korean Registered Utility Model No. 20-0311397,

A metal band fixedly coupled to the outer surface of the receptacle body in a state of being electrically connected to the ground terminal is provided with a fastening bolt for fastening the ground wire between the pair of opposing vertical bent pieces formed by cutting both widthwise left and right ends of the metal band in parallel. So that the ground wire can be connected in such a manner that the drawn ground wire is fixed by a pressing piece so as to be connected.

However, in the conventional art of the related art, in order to connect the ground wire, first, the fastening bolt for fixing the ground wire is unfastened by a screwdriver,

A ground wire is inserted between the vertical bent part of the metal band and the pressing piece,

It is troublesome to fasten the fastening bolts for fixing the ground wire again,

The work process and time required for connection of the ground line are increased,

When the fastening bolts for fixing the ground wire are fastened, when not tightly fastened,

There was a problem that ground fault occurred,

Since the metal band has to be projected to the rear side of the receptacle body in order to secure the connection portion for connecting the ground wire to the metal band,

There is a problem that the thickness of the receptacle body becomes thicker by the thickness of the connecting portion.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of conventional ground line connection systems,

The ground wire connecting piece formed by punching the metal band at the portion where the leaf spring inserting request is located inward is inserted into the upper and lower ends of the leaf spring inserting request,

A shaft hole is formed in the upper part of the intermediate partition wall and a drive shaft of a leaf spring pressing piece protruding inward from the shaft hole is inserted.

When the leaf spring pushing piece is pressed when the grounding line is connected or disconnected, the pushing rod projecting inward while the pushing piece performs the seesaw motion about the drive shaft presses the leaf spring to connect or disconnect the grounding line inserted between the leaf spring and the grounding wire connecting piece By doing so,

It is possible to more easily and quickly connect the ground wire to the metal band so that the workability due to the connection of the ground wire can be greatly improved,

The connecting force between the metal band and the ground wire is strengthened so that the connection state of the ground wire is stably maintained,

A ground connection portion for connecting a ground wire to the metal band is formed inside the socket body inside the metal band so that the thickness of the socket body can be prevented from becoming thick.

The ground wire connection structure of the recessed type electrical outlet of the present invention,

When a leaf spring pushing piece is pressed when a grounding line is connected or disconnected, a pushing rod projecting inward while the pushing piece performs a seesaw motion about the drive shaft presses the leaf spring to connect or disconnect a grounding line inserted between the leaf spring and the grounding line connecting piece By making it possible to cancel,

It is possible to more easily and quickly connect the ground wire to the metal band so that the workability due to the connection of the ground wire can be greatly improved,

The connecting force between the metal band and the ground wire is strengthened so that the connection state of the ground wire is stably maintained,

The earthing connection portion for connecting the ground wire to the metal band is formed inside the socket body inside the metal band so that the thickness of the socket body can be prevented from becoming thick.
