JPH08106950A - Electrically operated pulling-out plug - Google Patents

Abstract

PURPOSE: To simply pull out a plug from a receptacle by pushing a passive part of a sandwiching piece by an L-shaped arm slidably inscribed in a central hole of a coil, and opening and closing the sandwiching piece. CONSTITUTION: An electric current of an electric wire 7c passes through a push switch button from an electric wire 7a in an appliance, and is connected to a diode and a resistance, and flows to a coil. At this time, when the push button provided in the electric appliance is pushed, voltage of the electric wire 7a flows in the diode and the resistance, and is connected to a coil 4 after a flow and pressure are reduced, and electromagnetic force is generated in a coil core 14. When an iron core bar 5 is attracted, in an L-shaped arm 9, a pushing plate 9a on the pulling end moves a passive part 16, and opens a sandwiching port of a sandwiching piece 10, and slips out of a groove of a pulling-out bar 2. Then, the pulling-out bar 2 jumps out by repulsion of a spring 3, and runs against a receptacle, and a plug is pulled out by its reaction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric withdrawal plug in which the electric cord can be operated after the electric instrument is used so that the plug can be automatically pulled out from an outlet.

[0002]

2. Description of the Related Art Conventionally, when a plug inserted into an outlet after hitting an electric appliance is pulled out, the plug is moved to a place where the outlet is located and pulled out by hand.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to remove the plug from the outlet by operating the device in front of the outlet and pulling it out, so that the trouble of moving to the outlet and removing it by hand can be saved. , An electric extraction plug.

[0004]

According to the present invention, a pull-out rod 2 which is inserted through a spring 3 in the center of a main body 1 and is slidably attached to a state in which it is extended between two electrode pieces 6, is provided.
Next, the groove 2b is formed by making the tip 2a of the spring into a plunging angle, and the stop plate 2c of the spring 3 is provided almost in the middle. The holding piece 10 is operated by the spring 11 on the column 12 so as to sandwich the groove 2b. The iron core rod 5 with the brim 8 attached in a slanted state was slidably installed in the central core hole 14 of the coil 4 by passing it through the hole 13 of the L-shaped arm 9 in a state of being pulled by the brim 8. , The push plate 9a attached to the end of the L-shaped arm 9 is provided with a holding piece 10 via a support shaft 15.
An electric extraction plug which is mounted in a state in which the passive portion 16 of the above is pushed to enable opening and closing of the holding piece 10.

[0005]

The present invention has the above-described structure. When using the present invention, when the plug is inserted into the outlet, the extraction rod 2 pushes against it, and the spring 3 is compressed and contracted. Push the mouth open to clamp the extraction rod 2 in the groove 2b, and when installing, insert the plug completely into the outlet until the gripping piece 10 slides into the groove 2b of the extraction rod 2 of the plug, and connect the electrical appliance. When using the push button provided on the device when pulling out the plug after use, the current of 7a connected to the device flows to the diode and the resistance, is reduced to direct current, passes through the coil 4, and connects. Flowing through the electric wire 7b, a magnetic force is generated in the coil at that time, the iron core rod 5 is pulled, the L-shaped arm 9 is moved, and the pushing plate 9a attached to the end portion via the support shaft 15 holds the holding piece 1.
The passive portion 16 of 0 is pushed to open and close the holding piece 10, and at that time, the groove 2b of the extraction rod 2 held by the holding piece 10
The pull-out rod 2 comes off and hits the outlet by the repulsive force of the spring 3, and the plug pulls out by the reaction.

EXAMPLES The examples shown in the drawings will be described in more detail below. The electric extraction plug of this embodiment uses three electric wires for connecting the electric appliance and the plug, and the two wires 7a and 7b connect the plug and the electric appliance to each other. The 7c wire was connected to the 7a wire in the electric device through the coil wire, the diode, the resistor, and the push button from the 7b wire.

The electric current of the electric wire 7c passes through the push switch button from the electric wire of 7a in the device and is connected to the diode and the resistor and flows to the coil. The diode is 5V at 200V-2A.
A 12M-0.2MM wire is passed through a 0 ohm resistor into a coil wound in a cylinder having a diameter of 5MM and a length of 25MM, and its end is connected to an electric wire of 7b.

When using this, by pushing the push button provided in the electric appliance, the voltage of AC100V of the line 7a flows through the diode and the resistance, and is reduced and decompressed to the coil 4 and the electromagnetic force is applied to the coil core 14. When the iron core rod 5 is sucked, the arm 9 is pulled and the end 9a moves 16 to hold the holding piece 10.
Opening the nipping opening of the pull-out rod, the pull-out rod 2 is disengaged from the groove 2b of the pull-out rod 2, and the pull-out rod 2 pops out due to the repulsion of the spring 3.

INDUSTRIAL APPLICABILITY The present invention is suitable for electric appliances and the like that are often used with plugs replaced, and particularly in vacuum cleaners, irons, electric heaters, mobile small electric machine tools, etc. However, I would like to omit this electric extraction plug, which eliminates the drawbacks.
