Abstract

<P>PROBLEM TO BE SOLVED: To provide an outlet tap which can prevent the sticking of dust and fiber particles or the like on a bayonet plug electrode and near an electrode hole of an outlet tap, and can minimize an outflow of sparks when the sparks are generated between the outlet tap and a connection plug. <P>SOLUTION: The out let tap 1 includes a structure in which a bayonet plug insertion portion of the outlet tap has a dug and concave structure and a metal electrode cannot be seen from an upper side when the bayonet plug is inserted, and especially dust and fiber particles coming down from an upper side are not deposited on the electrode and a risk of sparks or the like between the electrode can be avoided to allow care-free usage even if the bayonet plug 3 is connected for a long period. A lower corner of the dug concave portion is removed to have a minimal angle of inclination and the deposit of dust on the portion 5 can be avoided even if the outlet tap is not connected with the bayonet plug. Moreover, since the outlet tap has a dug type and a gap between the connection plug electrode and an external atmosphere is made smaller, an outflow of sparks can be minimized even if the sparks should be generated. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は，コンセントタップ使用時の差込プラグの金属電極の露出におけるスパーク発火事故防止の安全性に関する。  The present invention relates to the safety of preventing spark ignition accidents when exposing the metal electrode of the plug when using the outlet tap.

従来，家庭．その他で使用されているコンセントタップにおいてはコンセントタップカバーのモールドの表面がフラット構造のものであり．特にこれを壁面に取付けて使用する場合はコンセントタップと差込プラグの隙間から粉塵．綿埃等が差し込みプラグの電極上へ直接堆積しスパーク発火火災の原因となっているが．この事の対策としての製品は見当たらない。  Traditionally home. Outlet taps used elsewhere have a flat structure on the surface of the outlet tap cover mold. In particular, when this is mounted on a wall, dust is generated from the gap between the outlet tap and the plug. Cotton dust etc. accumulates directly on the plug electrode, causing sparks and fires. There is no product to deal with this.

現状，家庭の冷蔵庫．洗濯機．テレビ等大型電化製品の差込プラグは当該電気機器の裏側壁面のコンセントタップ等に何年間も接続されたままで忘れ去られ．粉塵まみれとなっている事が多く．何時スパーク火災が起きても不思議では無い状態にある。  Currently, home refrigerator. Washing machine. The plugs of large electric appliances such as TVs are forgotten for years, connected to the outlet tap on the back side wall of the electrical equipment. Often dusty. No matter when a spark fire breaks out, it's no wonder.

なお，本願発明に関する公知技術として次の特許文献１〜２を挙げることができる。  In addition, the following patent documents 1-2 can be mentioned as a well-known technique regarding this invention.

上述の如く，従来のコンセントタップは安全性を度外視し．外見上の美観．使い易さのみを重視したものであり．何時も目の行き届く手元で使用するならいざ知らず．目の行き届かない大型家具．家電製品の裏の壁面．物陰等で長期間コンセントタップに差込プラグを接続しっぱなしとする場合の安全性の確保は難しい。  As mentioned above, the conventional outlet tap is not safe. Appearance of beauty. It emphasizes only ease of use. Don't know if you always use it with your eyes close. Large furniture out of reach. The wall on the back of home appliances. It is difficult to ensure safety when the plug is left connected to the outlet tap for a long time in the shade.

このため，現状では一部の不安を感じる人々が時々．コンセントタップから差込プラグを引き抜いて粉塵．綿埃等を清掃して再度接続することで不便を感じながらも我慢しているのが実態である。  For this reason, people who feel some anxiety are sometimes present. Pull out the plug from the outlet tap to remove dust. The reality is that they endure while feeling inconvenience by cleaning and reconnecting cotton dust.

本発明は，このような点に鑑みて成されたものであり，その目的は．コンセントタップ（特に壁面取付けの物）に長期間に渡って差込プラグを接続しっぱなしにしても．差込プラグの金属電極に粉塵．綿埃が付着せず．又．差込プラグ未装着の場合でもコンセントタップ掘り込み凹部の下部の角を除去して傾斜を最小限にしている為．その部分への粉塵堆積は発生せず．万一差し込みプラグ電極間でスパークが発生してもコンセントタップと差込プラグの間にスパーク火花を閉じ込めて外部への流出を最小限とする事により．スパーク火災に対する安全性の向上をはかる事が出来る様にする事にある。  The present invention has been made in view of these points, and its purpose is as follows. Even if the plug is left connected to the outlet tap (especially wall-mounted) for a long time. Dust on the metal electrode of the plug. Cotton dust does not adhere. or. Even when the plug is not installed, the inclination is minimized by removing the corner at the bottom of the outlet tap digging recess. There was no dust accumulation on the area. In the unlikely event that a spark occurs between plug plug electrodes, by confining a spark spark between the outlet tap and the plug plug, the outflow to the outside is minimized. The goal is to improve safety against spark fires.

上述の目的を達成する本発明の構造は．コンセントタップのカバーの差込プラグ用の電極穴の部分の回りを差込プラグの形状に合わせた掘り込み式凹面構造としたことを特徴とする。  The structure of the present invention that achieves the above object is as follows. It is characterized by a digging concave surface structure in which the area around the electrode hole for the plug of the plug of the outlet tap is matched to the shape of the plug.

コンセントタップに差込プラグ取付け時は特に壁面にコンセントタップを取付けて使用する場合においては上空から下を目視してもコンセントタップと差込プラグの間の隙間は見渡せず．差込プラグの金属電極も見えない構造となっている。  When the plug is attached to the outlet tap, especially when the outlet tap is attached to the wall surface, the gap between the outlet tap and the insertion plug cannot be seen even from the sky. The metal electrode of the plug is also invisible.

以上説明したように本発明によれば，コンセントタップに差込プラグを取付けた場合．特にコンセントタップの壁面取付けの場合でも長期間の保守点検無しの状態にても従来品に比較して安心して使用出来る為．今までと比較して安全性に大幅な向上が期待出来る。  As explained above, according to the present invention, when the plug is attached to the outlet tap. In particular, even when the wall surface of the outlet tap is installed, it can be used with confidence compared to the conventional product even when there is no long-term maintenance inspection. A significant improvement in safety can be expected compared to the past.

以下，本発明の実施の形態を図面に基づき詳細に説明する。  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The connecting plug 3 insertion part of the outlet tap surface mold cover 2 has a digging concave 4 structure. The corners of the concave lower part 5 at the time of use in the wall mounting are removed to make the minimum inclination.
