Abstract

<P>PROBLEM TO BE SOLVED: To provide an outlet for a rotary plug with a function enabling even a frail user to pull off the rotary plug easily with a small force. <P>SOLUTION: With a principle of levers and characteristics of the rotary plug utilized, a device is added which moves one end (a top part) of the rotary plug downward and the other end (a blade part) upward with a fulcrum set at the outlet part. <P>COPYRIGHT: (C)2003,JPO

Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention 2. Description of the Related Art A conventional outlet uses a method of directly holding the plug or pulling out an electric wire when the plug is extracted from a blade receiving portion. The same applies to the case where a rotary plug that has been widely used at present is used. In this case, a considerable amount of force is required to remove the wire, and it has been a factor of failure such as disconnection. [0003] In particular, in the case of a rotary plug, the blade may bend if the force is not removed while paying attention not to rotate the plug. [0004] How to make it possible to pull out a rotary plug connected to an outlet with a small force, and how to make it possible to pull out in a short time. It is an issue. [0005] What is possible with a small force to remove a rotary plug. This combines the ability of a rotary plug to rotate and the principle of leverage. [0006] Ordinary outlets have a flat surface. It is to create a form in which a protrusion serving as a fulcrum of the lever is installed on the surface at right angles to the blade receiving part, and the rotary plug is pulled out while rotating. [0007] When installing a protrusion serving as a fulcrum of a lever,
In order not to damage the outer shell of the plug as much as possible, the sharpness is eliminated by a semi-cylindrical projection to make it easier to rotate. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS When the rotary plug 2 is removed from a state in which the rotary plug 2 is inserted into the rotary plug outlet 1 according to the present invention, the rotary plug 2 is rotated in the direction of a projection 3 serving as a fulcrum, and a fingertip ( Pressure is applied downward at (power point) 5. The pressurized rotary plug 2 has its fingertip (point of force) 5 pressed downward around the projection 3 serving as a fulcrum, and the other (insertion blade) moves upward. As a result, the rotary plug 2 comes out of the blade receiving portion 4 of the rotary plug outlet 1. Further, since this device uses the principle of leverage, the force applied to the fingertip (point of force) 5 can be reduced. According to the present invention, a non-powerful user can remove the rotary plug from the outlet with a smaller force than before. Since an unreasonable load is not applied to the plug or the electric wire, occurrence of an accident such as disconnection can be prevented.

Claims (1)

Claims: 1. A projection is provided on the outer shell of the outlet at a right angle to the blade receiver. When pulling out the rotary plug, use the rotation function, press downward on the vicinity of the cord connection part of the rotary plug so that the upper end of the protrusion becomes the fulcrum of the lever,
A device that allows easy removal of plugs.
