Description

【０００１】
【産業上の利用分野】
本件の発明は漏電保護プラグと称し，コンセントと負荷機器プラグの中間に設置される差込接続型の漏電遮断器に関する。
【０００２】
【従来の方法】
従来，前述の漏電保護プラグには図５のようなものが知られている。すなわち，電源側には２本のプラグ刃と負荷側には２個の刃受金具を備え，その間を接点装置を介して導体で接続し，導体は変流器を貫通し，変流器の出力は増幅されてコイルを駆動し，コイルは接点装置を引き外すように作用するもので，該装置から負荷側で発生した漏電を検知して負荷への電源供給を遮断するもので，漏電保護装置のない電路に接続されたコンセントから電源を供給される電動工具や機器の漏電や感電による事故防止をする上で有用であった。
【０００３】
しかしながら近年は，安全性を高めるためコンセントや負荷機器には，ターミナルや電線やプラグ刃や刃受けなどによるアース極を設けたものが増加しているが，そのようなコンセントや負荷機器に対しては前述の従来の漏電保護プラグでは，アース極の接続手段がないために対応できなかった。すなわち，コンセントがアース極の刃受金具付きの場合では，漏電保護プラグにアース極のプラグ刃がないので負荷側のアース線をコンセントのアース極に接続することができず，また負荷機器側がアース極のプラグ刃付き３Ｐプラグの場合，負荷側のアース極のプラグ刃が邪魔になって，漏電保護プラグの刃受金具に負荷機器のプラグを差し込むことができなかった。
【０００４】
この場合，漏電保護プラグのプラグ刃と刃受金具をアース極付の３Ｐにする方法が考えられるが，その場合使用するコンセントが３Ｐのものに限られるという不具合が生じる。現状では，コンセントも負荷機器のプラグも２Ｐや３Ｐ，またアースターミナルやアース線付きのものなど様々な種類のものがあり，どのようなコンセントやプラグでも種類を選ばずに使用できる漏電保護プラグは従来なかった。
【０００５】
なお，プラグのアダプターとして，プラグを３Ｐから２Ｐへ，またアース線付きの２Ｐプラグを３Ｐプラグに変換するようなものは従来からあったが，漏電遮断機能付きのものはなく，また漏電遮断器の特性として，機器アースがとってあるほうが，保護機能が確実化するという特徴がある。
【０００６】
【課題】
そこで本件の発明は，プラグやコンセントがどのような種類でも使用できる漏電保護プラグを提供することを課題としている。
【０００７】
【課題を解決するための手段】

【０００９】
請求項２は，電源側には２本のプラグ刃と負荷側には２個の刃受金具を備え，その間を接点装置を介して導体で接続し，導体は変流器を貫通し，変流器の出力は増幅されてコイルを駆動し，コイルは前記接点装置を引き外すように作用するとともに，電源側には根元を軸支されて折りたたみ可能としたアース極プラグ刃と，アース線と，負荷側にはアース極の刃受金具と，該アース極の刃受金具と電気的に接続されたアース端子とを備え，前記アース極プラグ刃はアース極の刃受金具と電気的に接続されて，前記アース線はアース極の刃受金具と電気的に接続されたアース端子に対しねじにより着脱可能としたことを特徴とするアース極付き漏電保護プラグを提供したものである。
【００１０】
さらに，請求項３は，電源側には２本のプラグ刃と負荷側には２個の刃受金具を備え，その間を接点装置を介して導体で接続し，導体は変流器を貫通し，変流器の出力は増幅されてコイルを駆動し，コイルは前記接点装置を引き外すように作用するとともに，電源側にはスライドロック式で突出収納自在としたアース極プラグ刃と，アース線と，負荷側にはアース極の刃受金具と，該アース極の刃受金具と電気的に接続されたアース端子とを備え，前記アース極プラグ刃はアース極の刃受金具と電気的に接続されて，前記アース線はアース極の刃受金具と電気的に接続されたアース端子に対しねじにより着脱可能としたことを特徴とするアース極付き漏電保護プラグを提供したものである。

[Industrial application fields]
The present invention relates to an earth leakage circuit breaker of a plug-in type that is called an earth leakage protection plug and is installed between an outlet and a load device plug.
[0002]
Conventional method
Conventionally, the above-described leakage protection plug is known as shown in FIG. That is, two plug blades are provided on the power supply side and two blade brackets are provided on the load side, and a conductor is connected between them via a contact device. The conductor penetrates the current transformer, The output is amplified to drive the coil, and the coil acts to trip the contact device. It detects leakage on the load side from this device and shuts off the power supply to the load. It was useful in preventing accidents due to electric leakage or electric shocks of power tools and equipment that were supplied with power from an outlet connected to an electric circuit without equipment.

In recent years, however, there has been an increase in the number of outlets and load devices provided with a ground electrode such as terminals, electric wires, plug blades, and blade holders in order to improve safety. The above-mentioned conventional leakage protection plug cannot be handled because there is no means for connecting the ground electrode. In other words, when the outlet is equipped with a grounding edge blade bracket, the earth leakage plug cannot be connected to the grounding electrode of the outlet because the earth leakage protection plug does not have a grounding blade, and the load equipment side must be grounded. In the case of a 3P plug with a pole plug blade, the load blade could not be inserted into the blade bracket of the earth leakage protection plug because the plug blade of the earth electrode on the load side was in the way.
[0004]
In this case, a method is possible in which the plug blade and blade bracket of the earth leakage protection plug are made to be 3P with a grounding electrode, but in this case, there is a problem that the outlet used is limited to 3P. At present, there are various types of outlets and plugs for load devices such as 2P and 3P, and those with earth terminals and earth wires, and any earth leakage protection plug that can be used regardless of the type is available. Never before.
[0005]
In addition, there has been a conventional plug adapter that converts a plug from 3P to 2P, and a 2P plug with a ground wire to a 3P plug. The characteristic is that the protective function is ensured when the equipment ground is taken.
