  However, when the guardian's eyes cannot reach, the outlet cover or the like can be easily removed or opened, which is not a safe state.

  Therefore, the present invention provides a device that emits sound in the outlet cover, and emits an alarm sound when the outlet cover is removed from the plug insertion hole of the power outlet so as to alert and inform the surroundings.

  In order to achieve the above-mentioned object, the present invention is a device for inserting a latching leg of an insulating material of an outlet cover into a plug insertion hole of a power outlet, and a sound generator using a battery as a power source in the outlet cover and a convex shape And a convex shape of the convex push switch is provided on the locking leg side, and a sound is emitted when the locking leg is removed from the plug insertion hole.

  In addition, a manual switch is provided in series with a convex push switch for turning on and off the sound generator in the outlet cover. By turning off the power supply with a manual switch, the alarm sound can be stopped even if it is removed.

  Since the present invention is configured as described above, the following effects can be obtained.

  According to the first aspect of the present invention, when a young child removes the outlet cover from the power outlet, a buzzer sounds and informs surrounding people of the abnormality, thereby avoiding danger such as electric shock.

  According to the invention described in claim 2, the buzzer sound is generated by removing the outlet cover from the power outlet. However, the buzzer sound that continues to ring is provided by providing a manual switch in series connection with the convex push switch. It can be stopped and is convenient for the treatment after removal.

Embodiments of the present invention will be described with reference to the drawings.
1 to FIG. 4 and circuit diagram 5, it is the figure in 1st Example of the outlet cover which emits the alarm sound based on this invention.
Reference numeral 1 denotes a plastic outlet cover body made of an insulating material, and 3 denotes an insulator locking leg provided on the front side of the outlet cover. Reference numeral 2 denotes a convex push switch provided on the locking leg side. This is a function that turns on and off when pressed out with the convex push switch 2.
The operation of pushing the convex shape of the convex push switch 2 forward by providing four springs at the rear part of the convex push switch 2 works.
In the circuit diagram 5, 5 is a buzzer built in the outlet cover 1, and 6 is a button battery. 8 is a wall outlet, and 9 is a plug insertion hole. Reference numeral 7 denotes a groove-shaped recess formed on the side surface of the outlet cover 1. When the recess 7 is removed from the power outlet 8, the recess 7 is held while being pinched with a fingertip.
Also, in FIG. 4, 10 is a main body of the outlet cover temporary stopper that emits an alarm sound, 11 is a temporary insertion hole, and 12 is a screw hole that is fixed to a wall surface or the like.
Therefore, the outlet cover temporary stopper is a device that stops the buzzer sound after removing the convex outlet cover 1 from the power outlet 8.

  Therefore, in order to maintain a safe state in the unused power outlet 8 in use, the insulating leg 3 of the insulating material of the outlet cover 1 is inserted into the plug insertion hole 9, and the locking leg 2 of the inserted insulating material is inserted. Since the spring of the electrode side adheres closely to the surface of the power outlet 8 and the convex shape of the convex push switch 2 is pushed inside, the electrode of the push switch 2 is separated and the switch operation is turned off. The buzzer sound can be stopped.

Moreover, when removing the outlet cover 2, it can be removed by pulling while holding the concave portion with the fingertip. Therefore, when the convex push switch 2 is pushed forward by the force of the spring 4, the electrode of the push switch 2 comes into contact and turns on, and a buzzer sounds. By attaching to 11, the buzzer sound stops again. Moreover, the outlet cover temporary stopper 11 is installed at a slightly higher position.
For this reason, when a young child is removed by mischief, a buzzer sounds immediately and informs the surrounding people.

  FIGS. 6 and 7, circuit diagrams 8 and 9, and circuit diagram 10 show a second embodiment.

6, 7, and circuit diagram 8, reference numeral 21 denotes a manually-locked push switch in which a lock-type switch 21 </ b> A is formed on a convex coaxial switch 2 </ b> A on a convex coaxial line.
In the circuit, the push switch 2A and the lock switch 21A are connected in series.
Reference numeral 22 denotes a key-shaped hole having a shape in which a notch is provided at one end of the round shape of the manual locking push switch 21.

  Therefore, when the outlet cover 1 is inserted into the plug insertion hole 9 of the power outlet 8, the lock-type switch 21A is turned in the on direction as shown in FIG. By fitting the 22 notches, the convex portion is pulled. Therefore, when the insulating material locking leg 3 is inserted into the plug insertion hole 9, the convex push switch 2A is pulled off. The buzzer stops here.

On the other hand, when the outlet cover 1 is removed from the power outlet 8, the push switch 2A is pushed out by the repulsive force of the spring 4 and is turned on to generate a buzzer sound.
Here, when the buzzer sound is stopped, the buzzer sound can be stopped by turning off the manual lock switch 2B.

  As shown in FIG. 9 and circuit diagram 10, reference numeral 31 denotes a push-type auxiliary switch. The push-type auxiliary switch 31 has a circuit configuration connected in series with the convex push-button switch 2C, and the push-type auxiliary switch 31 performs the following operation by setting it to a function that is turned off only while being pressed.

  Therefore, as described above, when removing from the state where the plug socket 9 of the power outlet 8 is mounted, it can be removed while pressing the button of the push-type auxiliary switch 31 with a finger while stopping the buzzer sound. Is. By attaching to the outlet cover temporary fastener 10 in this state, it can be performed without making a sound.
