本考案は二重絶縁構造の携帯用電気鉋にかける放電防止
装置に関するものである。[Detailed Description of the Invention] The present invention relates to a discharge prevention device for a portable electric planer having a double insulation structure.
従来の外枠が合成樹脂からなる二重絶縁構造の携帯用電
気かんなでは、合成樹脂製ベルトと金属プーリーとの回
転摩擦により静電気が発生し、発生した静電気がかんな
胴部に蓄積されていて、帯電された静電気が電位の異な
る接近したりャベース、フロントベースに放電する為、
ラジオノイズレベルが異常に高くなる欠点があった。In conventional portable electric planers with a double-insulated outer frame made of synthetic resin, static electricity is generated due to rotational friction between the synthetic resin belt and the metal pulley, and the generated static electricity is accumulated in the body of the planer. Because the charged static electricity is discharged to the nearby base or front base with different potential,
The drawback was that the radio noise level was abnormally high.
本考案の目的は、上記した従来技術の欠点をなくシ、静
電気の蓄積によう生じる放電を防止し、もってラジオノ
イズの発生を防止するものである。The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to prevent discharge caused by accumulation of static electricity, and thereby to prevent the generation of radio noise.
本考案は、金属プーリーと合成樹脂製ベルトとが、回転

ヤベース、フロントベースの３者を電気的に導通するよ
う工夫したものである。This invention consists of three parts: the planer body, rear base, and front base, each of which is insulated, in order to eliminate the discharge phenomenon caused by static electricity generated by friction between the metal pulley and the synthetic resin belt during rotation. It was devised so that it would be electrically conductive.
以下本考案の実施例を図面にもとすいて説明する。Embodiments of the present invention will be described below with reference to the drawings.
符号１４は二重絶縁構造の電気鉋全体を示す。Reference numeral 14 indicates the entire electric plane having a double insulation structure.
エンドブラケット９、ハウジング１０は合成樹脂製であ
る。The end bracket 9 and housing 10 are made of synthetic resin.
エンドブラケット９には導線８が射出成形時、一体間に
固定する等の方法で固定されている。A conductive wire 8 is fixed to the end bracket 9 by a method such as being fixed between two pieces during injection molding.
本エンドブラケット９を電気かんな本例４に組込むと導
線８は常に、かんな胴部１を支持しているボールベアリ
ング２のａ点、フロントベース３とは０点で、リヤベー
ス４とはｂ点で接触する。When this end bracket 9 is assembled into the electric plane 4, the conductor 8 is always connected to the ball bearing 2 supporting the planer body 1 at point a, the front base 3 at point 0, and the rear base 4 at point b. Contact.
以上により、これら３者は電気的に接続され同電位にな
る。As a result of the above, these three are electrically connected and have the same potential.
従って、かんな胴部１とリヤベース４もしくはフロント
ベース３間には放電現象の発生はない。Therefore, no discharge phenomenon occurs between the planer body 1 and the rear base 4 or front base 3.
本考案の実施例において、かんな胴部１、フロントベー
ス３、リヤベース４の３者を電気的に接続した導体８に
は線材を使用した７５瓢板状のもの、その他いかなる形
状でもよい。In the embodiment of the present invention, the conductor 8 that electrically connects the planer body 1, front base 3, and rear base 4 may be made of wire and may be shaped like a 75-gourd plate, or may have any other shape.
導体８の固定は射出成形時に固定するほか、ネジによる
固定・接着剤による固定等いずれでもよい。The conductor 8 may be fixed during injection molding, or may be fixed using screws, adhesive, or the like.
又、かんな胴部１、フロントベース３、リヤベース４へ
の接触場所は、使用上支障なければどこでもよい。Further, the planer body 1, front base 3, and rear base 4 may be contacted at any location as long as it does not interfere with use.
更に、導体８の取付場所は、エンドブラケット９と対向
している側のハウジング１０であってもよい。Further, the conductor 8 may be attached to the housing 10 on the side facing the end bracket 9.
本考案によれば、プーリーと合成樹脂製ベルトとの回転
摩擦で発生する静電気によシ起る放電をなくすることが
でき、ラジオノイズレベルヲ低下することができる。According to the present invention, discharge caused by static electricity generated by rotational friction between the pulley and the synthetic resin belt can be eliminated, and the radio noise level can be reduced.
