Abstract

PURPOSE:To remove a power plug from a wall outlet remotely by furnishing a removal part in the middle of plug edges to be inserted in the wall outlet, and by furnishing a pushout part to energize it, a fixing part to detain the energization, and a tension part to disengage the detention. CONSTITUTION:When the body 1 is to be inserted in a wall outlet, the removal part 3 runs against the wall outlet and intruded into the housing 7. A spring 6a of pushout part 6 is contracted so that finally a hook of the removal part 3 is detained with the hook 4d of a fixing part 4. When it is pulled off from the wall outlet, turning-on of a switch on a control part 8 allows flowing of current through a coil of a tension part 5 to attract the lower magnetic substance of the fixing part, which will rotate round the axis 4c to disengage the detention, and the repulsion force of the spring 6a pushes out the wall outlet to permit the body 1 to be removed from the wall outlet remotely.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a power plug disconnection device used in electrical equipment and the like.

BACKGROUND OF THE INVENTION Conventional power plugs have to be removed from the outlet by holding the power plug itself by hand, as there is a risk of the cord breaking if the cord is pulled.

Problems to be Solved by the Invention With a power plug having a conventional configuration, if the user wishes to pull out the power plug at a location far from the outlet into which the power plug is inserted, the user must go to the outlet. In addition, since electrical outlets are usually installed below the wall, it was necessary to take a low position such as crouching down.

The present invention is intended to solve such problems, and an object of the present invention is to provide a power plug disconnection device that allows the plug to be unplugged from the power outlet even at a location far from the power outlet.

Means for Solving the Problems In order to solve the above-mentioned problems, the power plug disconnection device of the present invention includes a plug blade that is inserted into an outlet, a disconnection part disposed between the blades, and a disconnection part that energizes the disconnection part. an extrusion section;
A power plug main body comprising a fixing part that locks the detachable part against bias, a tension part for releasing the lock from the fixation part, and an operating part for operating the tension part. It consists of

Operation: With the above-described configuration, the power plug inserted into the outlet can be easily disconnected by remote control by operating the operating section without breaking the cord.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1, 2, and 3.

FIG. 1 is an external perspective view showing a state in which the power plug is unplugged from the outlet, FIG. 2 is an external perspective view showing the power plug in a state in which it is also inserted into the outlet, and FIG. 3 is a front view. In the figure, 1 is a power plug body (hereinafter referred to as the main body), which includes a plug blade 2 that is inserted into an outlet, and a detachable part 3 that is disposed between the plug blade 2 and is used to remove the main body 1 from the outlet. , a fixing part 4 that locks the detachable part 3 against bias, a tension part 5 that releases the lock of the fixing part 4, and a push-out part 6 that urges the detachable part 3 upward. and a housing 7 including these. The extrusion part 6 has a cylinder 6a parallel to the inner wall of the detachment part 3, and a spring 6b which is an elastic body provided on the surface of the cylinder 6a, and urges the separation part 3 upward. The structure is as follows.

Further, the lower end of the detachable part 3 is a hook-shaped part 3a, and when the main body 1 is plugged into an outlet, it is configured to be locked by the hook-shaped part 4d of the fixing part 4. . The fixed part 4 is made of a magnetic material, and is configured to rotate in one direction about the axis 4c when the magnetic force from the tension part 5 is applied, and the detachable part 3 descends to release the fixed part. 4 has a spring 4a that biases it to ensure this locking when it is locked, and a stopper 4b that restricts the rotational movement of the fixed part 5 when the magnetic force of the tensioning part 5 acts. are doing. The tension part 5 has a structure in which a coil is wound around a magnetic material, and when the operating part 8 is operated, it acts as an electromagnet by a DC power source (not shown), and the fixed part 4 made of a magnetic material The lower part of the holder is sucked to cause a rotational movement, and the detachable part 3, which is locked by the fixed part 4, is released. Further, 8 is an operating section for passing a current through the tension section 5.

Next, the operation will be explained.

When the main body 1 is inserted into an outlet, the upper part of the detachable part 3 hits the outlet and is pushed into the housing 7 as it is. At this time, the spring 6 constituting the extrusion part 6
b is compressed by the detachment section 3 and compressed between the detachment section 3 and the lower end of the extrusion section 6 to which the spring 6b is locked. Thereafter, at the same time that the main body 1 is completely inserted into the outlet, the spring 4a pulls the lower part of the fixed part 4, and the upper part rotates toward the detachment part 3 about the axis 4c, and the hook of the detachment part 3 is rotated. The shaped part 3a is the hook-shaped part 4d of the fixing part 4.
It is something that is locked in place.

Next, the case where the main body 1 is removed from the outlet will be explained. When the switch included in the operation section 8 is turned on, the tension section 5
The circuit is closed, a direct current flows through the coil constituting the tension section 5, and the tension section 5 acts as an electromagnet. As a result, the lower part of the fixed part 4 made of magnetic material is attracted,
The fixed part 4 rotates about the axis 4c in a direction away from the detachable part 3. In other words, the state in which the hook-shaped portion 3a of the detachable portion 3 is locked by the hook-shaped portion 4d of the fixed portion 4 is released by this rotational movement. The released part 3 releases the compressed spring 6b.
is pushed upward by the repulsive force. At this time, since the spring 6b extends along the surface of the cylindrical body 6a, the detachment part 3 is pushed straight upward without being tilted.

Therefore, the detachable part 3 can push the surface of the outlet perpendicularly to the wall surface with its upper end without losing the repulsive force of the compressed spring 6a. Therefore, the main body 1 can be disconnected from the outlet by remote control without the cord being disconnected.

In this embodiment, the operating section 8 is separate from the device having the main body 1, but it may of course be configured to be integrated with the device.

Effects of the Invention As described above, according to the present invention, the power plug can be easily removed from the outlet without having to take the trouble of going all the way to the outlet when unplugging the power plug.
