Description
【考案の詳細な説明】 この考案は、プラグ用栓刃の改良に関する。[Detailed explanation of the idea] This invention relates to an improvement of a plug blade.
従来のプラグ用栓刃を第１図、第２図に基づいて説明す
ると、栓刃１は、コンセント等の受刃に挿脱自在に取付
けられるため、十分な厚みを有して一定厚で形成され、
栓刃１の末端部には、コードの芯線を固着支持する支持
部２が設けられ、支持部２の両側には倒立片３が形成さ
れている。To explain the conventional plug blade based on FIGS. 1 and 2, the plug blade 1 is formed with a constant thickness with sufficient thickness because it can be detachably attached to the receiving blade of an outlet etc. is,
A support part 2 for firmly supporting the core wire of the cord is provided at the end of the plug blade 1, and inverted pieces 3 are formed on both sides of the support part 2.
上記支持部２は、コードの芯線を圧着又は半田付により
固着するため、栓刃より薄く形成され、また、上記倒立
片３は平板をプレス等で倒立させる作業を容易にするた
め、栓刃１と支持部２との接続部４には切欠き５が形成
され、切欠き部の倒立片３の高さは、第２図に示すよう
に、栓刃１の厚みより小さく形成されている。The supporting part 2 is formed thinner than the plug blade in order to fix the core wire of the cord by crimping or soldering, and the inverted piece 3 is formed to be thinner than the plug blade 1 in order to facilitate the work of inverting a flat plate with a press or the like. A notch 5 is formed in the connecting portion 4 between the support portion 2 and the support portion 2, and the height of the inverted piece 3 in the notch portion is smaller than the thickness of the plug blade 1, as shown in FIG.
上記のような栓刃を備えたプラグを使用する際に、プラ
グをコンセントに強固に固定しようとして、プラグの栓
刃を接近或いは離反するように力を付与する場合がある
。When using a plug equipped with the above-mentioned plug blades, a force may be applied to the plug blades to move them toward or away from each other in order to securely fix the plug to the outlet.
このように、栓刃の力を作用させると、栓刃と支持部と
の接続部が薄く形成されているため、接続部が折れ曲が
り、折れ部にアークが発生し、火災等の事故が発生する
恐れがある。In this way, when the force of the plug blade is applied, the connecting part between the plug blade and the support part is formed thin, so the connection part bends, and an arc is generated at the bent part, causing an accident such as a fire. There is a fear.
この考案は、以上の事情に鑑みてなされたもので、折損
が生じないようにして、プラグの事故を防止するように
したプラグ用栓刃を提供することを目的とする。This invention was made in view of the above circumstances, and aims to provide a plug blade that prevents breakage and prevents plug accidents.
以下、この考案を第３図第４図に示す実施例に基づいて
説明する。This invention will be explained below based on the embodiments shown in FIGS. 3 and 4.
第３図、第４図に示すように、所定の厚みで形成された
栓刃１の末端部には、コードの芯線を固着する支持部２
ａが設けられ、支持部２ａの両側には倒立片３ａが形成
されている。As shown in FIGS. 3 and 4, at the end of the plug blade 1 formed with a predetermined thickness, there is a support portion 2 to which the core wire of the cord is fixed.
a is provided, and inverted pieces 3a are formed on both sides of the support portion 2a.
この倒立片３ａは、第３図の一点鎖線で示すように、栓
刃１と一体に打抜かれた後、プレス等で起立させ形成さ
れる。The inverted piece 3a is punched out integrally with the stopper blade 1 and then erected using a press or the like, as shown by the dashed line in FIG.
上記倒立片３ａは高さの最低点が栓刃１の厚みよりも大
きくなるよう、栓刃１と支持部２ａとの接続部４ａは、
わずかに切欠かれているが、その切欠き５ａは完全にな
くしてもよい。The connection portion 4a between the plug blade 1 and the support portion 2a is such that the lowest point of the height of the inverted piece 3a is larger than the thickness of the plug blade 1.
Although the notch 5a is slightly cut out, the notch 5a may be completely eliminated.
なお、上記支持部２ａは、栓刃１よりも十分薄く形成さ
れており、上記栓刃１は、末端部が接続され、複数個が
一緒に形成され、使用する際に、−個宛分離される。The support portion 2a is formed to be sufficiently thinner than the blade 1, and the blades 1 are connected at their ends and are formed together in a plurality of pieces, and when used, they are separated into -pieces. Ru.
−二の考案は、以上のとお
り、栓刃の末端両側に設けた倒立片を倒立片の高さの最
低点が栓刃の厚みよりも大きくなるように形成している
ため、プラグに装着した栓刃を接近或いは離反するよう
に力を付与しても、その力に倒立片が十分に耐えるから
、栓刃が折れ曲がることがなく、栓刃による火災等の事
故を防止できる。- As mentioned above, the second idea is that the inverted pieces provided on both sides of the end of the plug blade are formed so that the lowest point of the height of the inverted piece is larger than the thickness of the plug blade. Even if a force is applied to move the blades toward or away from each other, the inverted pieces can sufficiently withstand the force, so the blades will not bend, and accidents such as fires caused by the blades can be prevented.
