Description

【考案の詳細な説明】 本考案は、電気器具の電源コードの保護装置付
き差し込みプラグに関するものである。
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plug with a protection device for a power cord of an electrical appliance.

従来の電気器具、例えば掃除機のようにコード
を引き出して使用するものは、コードリールから
コードを一杯に引き出した状態から更に引つ張つ
てしまうことがあり、そのためにプラグの差し込
み刃が破損したり曲がつたりするほか、コードリ
ールへの収納の際、プラグがストツパーとなるた
め衝撃を受ける。そしてこれらの衝撃が繰り返さ
れることによりコードが短期間で断線してしま
う。
With conventional electrical appliances, such as vacuum cleaners, where the cord is pulled out, the cord may be pulled even further from the cord reel, which can damage the plug blade. In addition to bending and twisting, the plug acts as a stopper when storing it on the cord reel, causing shock. If these impacts are repeated, the cord will break in a short period of time.

本考案は、簡単な手段によつて上記の欠点を除
去したものを提供するもので、その構造を図面に
基づいて説明する。
The present invention provides a simple means to eliminate the above-mentioned drawbacks, and its structure will be explained based on the drawings.

プラグの差し込み刃2の接続される接点ABを
設けたプラグ本体1を、絶縁性を有する樹脂で一
体成形し、この接点ABに対応するように、コー
ド7が接続される接点A′B′を取り付けた可動板
3を設ける。
The plug body 1, which has a contact AB to which the insertion blade 2 of the plug is connected, is integrally molded from an insulating resin, and a contact A'B' to which the cord 7 is connected is made in correspondence with this contact AB. The attached movable plate 3 is provided.

可動板3は、コード方向にレール6に添つてス
ライドし、差し込み刃方向にスプリング4により
絶えず押さえ付けられており、接点AとA,Bと
Bは、閉路されているものである。
The movable plate 3 slides along the rail 6 in the cord direction and is constantly pressed by the spring 4 in the direction of the insertion blade, and the contacts A and A and B and B are closed.

スプリング4は、プラグ本体1とストツパー5
によつて保持されており、ストツパー5は、コー
ド7上の適当な位置に設けられている。
Spring 4 connects plug body 1 and stopper 5
The stopper 5 is provided at an appropriate position on the cord 7.

レール6は、コードのねじりなどで生じる接点
のズレやハズレを防止するもので、プラグ本体1
の上下に絶縁性を有する樹脂で同時に一体成形し
たものである。
The rail 6 prevents the contacts from shifting or coming loose due to twisting of the cord.
The upper and lower parts are simultaneously integrally molded with insulating resin.

電源コードをある一定以上の力で器具側方向に
引つ張ると、接点が開路して器具は作動を停止
し、力を除去してやると接点が閉路して、器具は
再び作動する。
When the power cord is pulled toward the side of the appliance with more than a certain amount of force, the contacts open and the appliance stops working; when the force is removed, the contacts close and the appliance starts working again.

故に本考案の電源コードの保護装置付き差し込
みプラグは、器具利用者にコードの長さの限界を
知らせると共に、プラグ差し込み刃の破損や曲が
りを防止するほか、コードリールへの収納の際に
受けるプラグへの衝撃を本保護装置内のスプリン
グにより吸収し、コード断線の防止にも役立つう
え、電源コードの寿命を延ばす等の特徴を有する
ものである。
Therefore, the power cord protection plug of the present invention not only informs the equipment user of the cord length limit, but also prevents the plug insertion blade from being damaged or bent. The shock to the power supply is absorbed by the spring inside the protection device, which helps prevent cord breakage and extends the life of the power cord.
