[Problems to be solved by the device]

 In these conventional power plugs and outlets, the plug body is pulled out by moving the arm horizontally in the opposite direction with respect to the plug terminal insertion port of the outlet. However, despite the fact that the arm itself has enough power to pull out the plug, it was only the tenths of the finger of the arm that finally transmitted that power. Therefore, although various measures have been taken, there is nothing definitive that it requires a certain amount of fingertip power, except for those with electrical mechanisms. It was very difficult for a child and an old man who had no power when it was firmly plugged. The present invention is designed to easily remove the power plug and the outlet in order to solve these drawbacks.

[0004]

[Means for Solving the Problems]

 According to the first aspect, there is the plug terminal 6 and the sliding body 4 which holds the base end side of the plug terminal 6. There is a main body 1 having a cylindrical space in which a spiral concave-convex groove 3 is provided so that the sliding body 4 can be inserted and spirally rotatable in the front-back direction. Then, the sliding member 4 is pressed from the rear portion to position the spring 10 in the front direction of the cylindrical space. The present invention is a simple disconnection power plug having the above configuration. The cylindrical space in which the spiral concave and convex groove 3 is provided may be formed in the front cover 2 as in each of the examples introduced later. Further, the sliding portion 4 may be formed by integrally molding the plug terminal 6 and the cord 11 with a resin insert as in an embodiment introduced later. The number and shape of the plug terminals 6 may be three or rod-shaped other than the embodiment, and needless to say, there are various ones.

According to a second aspect of the present invention, the plug terminal 6 of the simple disconnection power source plug according to the first aspect is used as a plug terminal receiving shell 13. And, it is a simple disconnection power outlet which has the other structure as the same structure as that of claim 1. In addition, also in an Example, it is based on the thing of Claim 1.

[0006]

[Action]

 The simple disconnection power plug of claim 1 according to the present invention is disconnected from the outlet as follows. A finger is put on the knob 12 formed on the plug body, or the plug body is held so that the finger does not slip and is rotated in one direction. (At this time, the outlet is fixed so as not to rotate in the same direction as the plug.) Then, since the plug terminal 6 is inserted into the outlet, the sliding body 4 does not rotate simultaneously with the main body 1. Then, the force of the rotational motion of the main body 1 is transmitted to the spiral convex portion 5 correspondingly formed on the sliding body 4 through the spiral concave and convex groove 3 provided therein. From this relationship, the force of the rotational movement changes in the vertical direction in which the sliding body 4 is detached from the outlet, and the plug terminal 6 is detached from the outlet and pulled up inside the main body 1. Thereafter, the spring 10 causes the sliding body 4 to return to its original position in the front direction of the cylindrical space of the main body 1.

The simple disconnection power outlet of claim 2 according to the present invention is disconnected from the plug as follows. Put a finger on the knob 12 formed on the outlet body, or hold the outlet body so that the finger does not slip, and rotate the outlet body in one direction. (At this time, the plug is fixed so as not to rotate in the same direction as the outlet.) The following operation is the same as that of claim 1 except that the plug terminal 6 of claim 1 is replaced by the plug terminal receiving fitting 13. the same.
