Abstract

PURPOSE:To make a power supply plug to be easily separated from a plug socket by attracting the lower part of the fixed part consist ing of a magnetic substance to make rotation to be started so as to release the separation part engaged by the fixed part. CONSTITUTION:When a switch owned by the operation part 7 turns on, a circuit of the tension part 5 is closed to flow a DC current to a coil constituting the tension part 5 so that the mention part 5 acts as an electromagnet. Consequently, the lower part of the fixed part 4 constituted by a magnetic substance is attracted so that fixed part 4 starts rotation in the direction to be separated from the separation part 3 centering about an axial centerline 4c. That is, a hook-shaped part 3c of the separation part 3 having been engaged with a hook-shaped part 4d of the fixed part 4 comes to be released from the engaged state because of this rotation. The separation part 3 released from this engagement is pushed out upward by resiliency of a spring having been in a compressed state. Thereby, a plug socket, in which the separation part 3 having been plugged in, is pushed out so as to enable a power supply plug proper 1 to be easily pulled out.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a power plug used in electrical equipment and the like.

BACKGROUND OF THE INVENTION Conventional power plugs have to be removed from the outlet by pulling the cord by the main body of the power plug, as there is a risk of the cord breaking.

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 has been made to solve such problems, and an object of the present invention is to provide a power plug that can be unplugged from an outlet even at a location far from the outlet.

Means for Solving the Problems The technical means of the present invention for solving the problems described above includes: a plug blade that is inserted into an outlet, a detachment part that is urged upward by an elastic body provided in the middle; The main body includes a fixing part for locking the detachable part, a tension part for releasing the lock of the fixation part, and an operation part for operating the tension part. be.

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

FIG. 1 is an external perspective view showing the power plug of the present invention when it is unplugged from the outlet, and FIG. 2 is an external perspective view showing the power plug of the present invention when it is inserted into the outlet.

First, the configuration will be explained.

In the figure, 1 is a power plug main body (hereinafter referred to as the main body), a plug blade 2 that is inserted into an outlet, and a plug blade 2 that is inserted into an outlet.
A detachable part 3 for removing the main body from an outlet disposed in the middle of the main body, a fixing part 4 for locking the detachable part 3, and a tension part 5 for releasing the fixing part 4. It is composed of a housing 6. The detachment part 3 has a guide part 3a.
A spring 3b, which is a knee elastic body of the guide portion 3a1', is engaged with the guide portion 3a1' to urge the detachment portion 3 upward. Note that a guide portion that locks the winding end portion of the spring 3b is not shown. Further, the lower end of the detachable part 3 is a hook-shaped part 3, which is configured to be locked by the hook-shaped part 4d of the fixing part 4 when the main body is plugged into an outlet. The fixed part 4 is made of a magnetic material, and when the magnetic force from the tension part 5 is applied, the axial center 4
It is configured to rotate in one direction around c, and when the release part 3 descends and the fixing part 4 locks it, a spring 4a and a tension force are applied to ensure this locking. It has a stopper 4b for regulating the rotational movement of the fixed part 5 when the magnetic force of the part 5 acts. The tension part 5 has a coil wound around a magnetic material (14 coils), and when the operation part 7 is operated, it acts as an electromagnet by a DC power source (not shown), and is a fixed magnet made of a magnetic material. The operating section 7 is a tensioning section that generates a rotary motion by attracting the lower part of the part to release the detachment section 3 that is locked by the fixing section 4. The operation section 7 also has an opening for applying current to the tensioning section 5. It is.

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. In this process, the spring 3b around the detachment part 3 is attached to the lower end of the detachment part 3 (where this spring is locked).
(not shown) and the guide portion 3a. 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 into three detachable parts about the axis 4c, and the hook of the detachable part 3 is rotated. The shaped portion 3c is engaged with the hook-shaped portion 4d of the fixed portion 4.

Next, unplug the main body 1 from the outlet (the case will be explained).
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 3C 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 release portion 3 is pushed upward by the repulsive force of the compressed spring. This force causes the detachment part 3 to push out the outlet into which it has been inserted, and the power plug main body 1 to come out.

In this embodiment, the operating section 7 may be separate from the device having the main body, or may be integrated with the device.

Effects of the Invention As described above, according to the present invention, it is possible to easily remove the power plug from the outlet without having to take the trouble of going all the way to the outlet when unplugging the power plug.
