Hereinafter, the use and operation of the one-touch outlet according to the present invention will be described in detail.

First, in the case of using the one-touch type outlet 100 according to the present invention, when the plug 200 of the electric device is inserted into the insertion holes 122 and 122 'formed in the pressing plate 120, the pressing plate 120, the pressing plate One side of the connection portion 174 protruding from the surface of the 120 and the ground terminal 204 of the plug 200 maintains an electrically connected state.

In such a state, the pressing plate 120 moves forward in the state of pressing the body of the plug 200 with one touch, and the protrusion piece 150 moves along the rail groove 136c of the cylinder part 136 and the plug 200. Terminal rods 202 and 202 'of the socket portion 110 are fitted in close contact with the terminal pieces 118a and 118a' of the terminal piece arrays 118 and 118 of the socket portion 110, and the inside of the wing portions 172 and 172 'of the ground connector 170. The electrical connection is made by being grounded to the outer surface of the protrusions 140c and 140c 'of the ground terminal block 140 and 140' on the side surface. Then, as the protrusion piece 150 moves the rail groove 136c, the bent portion 160a of the spring wire 160 having one end fixed to the cylinder portion 136 of the intermediate plate 130 is a protrusion piece ( It moves along the guide path 152 of 150 and is fitted into the V-shaped groove 154a of the guide protrusion 154.

At this time, when the physical force applied to the plug or pressing plate 120 is removed, the force acts to retract the pressing plate 120 from the cylinder portion 136 of the intermediate plate 130 by the elastic force of the coil spring 162, Since the bent portion 160a of the spring wire 160 is held in the V-shaped groove 154a of the guide protrusion 154 and cannot be separated, the terminal rods 202 and 202 'of the plug 200 and the terminal piece 118a, 118a ') will maintain the energized state.

In addition, in the state in which the body of the plug 200 is once more pressurized with one touch, the pressing plate 120 is advanced and the bent portion 160a of the spring wire 160 is along the guide path 152 of the protrusion 150. It moves and leaves the V-shaped groove 154a of the guide protrusion 154 and contacts the inclined surface 155a of the control protrusion 155.

When the molybdenum force applied to the body of the plug 200 is removed in such a state, the elastic force of the pressing plate 120 retreats from the cylinder portion 136 of the intermediate plate 130 by the elastic force of the coil spring 162. By this action, the bent portion 160a of the spring wire 160 is completely separated from the V-shaped groove 154a and guided by the control stone piece 155 to move along the guide path 152 to the intermediate plate 130. Since the pressing plate 120 is separated by a reverse distance. At this time, the terminal rods 202 and 202 'of the plug 200 are disconnected and disconnected from the terminal pieces 118a of the terminal piece array 118, and the wings 172 and 172' of the ground connector 170 fixed to the pressing plate 120 are disconnected. ) Slides the outer surfaces of the protrusions 140c and 140c 'of the ground terminal blocks 140 and 140' fixed to the socket 110.

On the other hand, when the plug 200 is to be rotated in a predetermined direction to fix the position, the wall 124 of the pressing plate 120 can be grasped and turned by hand regardless of the electrical on / off state. That is, when the pressing plate 120 is rotated in a predetermined direction, the rail protrusion 156 of the protrusion piece 150 is supported by the rail groove 136c of the cylinder portion 136 of the intermediate plate 130, so that the intermediate plate 130 is Are rotated together.

Accordingly, the peaks and valleys of the teeth 134a of the intermediate plate 130 are rotated while the teeth 134a and 134a 'are relatively moved along the valleys of the teeth of the socket 110 and the teeth 119a. At this time, the reason why the teeth 134a and 119a can be engaged with each other is due to the elastic force of the coil spring 114 fitted into the seating hole 118 of the socket part 110. Since the teeth 134a and 119a are pulled toward each other, they are naturally toothed in the process of moving with each other.

In particular, when the plug 200 is inserted to maintain the electrical connection state, the terminal rods 202 and 202 'of the plug 200 fitted to the terminal piece 118a are moved to the adjacent terminal pieces to maintain the electrical connection state. The wing portions 172 and 172 'of the ground connector 170, which are in contact with the outer surfaces of the ground terminal blocks 140 and 140', move the adjacent wing portions and make contact with the outer surfaces of the ground terminal blocks 140 and 140 '. Will be maintained.

At this time, the rotation angle of the pressing plate 130 in consideration of the number of terminal pieces 118a and the shape of the wing portion 172 of the ground connector 170, the outer wall portion of the socket portion 110 to maintain 45 ° at a time Four peaks and valleys of the teeth 119a formed at 119 are formed, respectively, and four peaks and valleys of the teeth 134a formed at the wall 134 of the intermediate plate 130 are also formed. Of course, this is only one example, it is also preferable to configure the number of teeth more closely.

In such a state, when the pressing plate 120 is pressed again with one touch, the bent portion 160a of the spring wire 160 formed in the V-shaped groove 154a of the guide protrusion 154 is formed in the V-shaped groove 154a. The terminal rod 202 of the plug 200 is separated from the cylinder plate 136 of the intermediate plate 130 by reversing the pressing plate 120 by the elasticity of the coil spring 162. 118a is separated and the power supply is cut off.

Therefore, when not using an electric device, it is possible to turn on and off the power supply by simple operation without removing the plug 200 from the outlet 100.

As described above, the embodiment of the present invention has been described similarly, but the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to the embodiment of the present invention.
