Description
【０００１】[0001]
本考案は一対のブラシホルダと嵌合する一対のストッププレートを有する携帯 用電動工具に関するもので、組立性を向上させるようにしたものである。 The present invention relates to a portable power tool having a pair of stop plates that fit with a pair of brush holders, and is intended to improve the assemblability.

従来の携帯用電動工具を丸のこ機を例にあげて図３〜図５を参照して説明する 。図３は丸のこ機１の正面図で、５はモータにより駆動される丸のこ刃、６は切 断時基準面となるベース、７は丸のこ刃５を覆うソーカバーである。図４は丸の こ機１の背面図で、２はモータを内蔵する金属製ハウジング、３はハウジング２ の後部開口部を覆うテールカバー、８はテールカバー３上に設けられたモータ冷 却風を吸込むための風窓、４はテールカバー３をハウジング２に固定するネジで ある。図５はハウジング２の部分断面図で、１８はモータを構成する図示しない アーマチュアのテールカバー３側の軸受を保持するハウジング２の軸受室、１０ はスットププレート、１１はブラシホルダ、１２はモータを構成するステータ、 １３はブラシターミナルである。ブラシホルダ１１は絶縁性のチューブ１４と導 電性のチューブ１５で構成されている。前記ステータ１２とブラシホルダ１１は 、ブラシターミナル１３で電気的に接続される。前記ストッププレート１０は、 ハウジング２とブラシターミナル１３間の沿面距離Ｌを大きくするためのもので ある。該ストッププレート１０により、加工時発生した切粉が風窓８より吸込ま れチューブ１４、チューブ１５に付着しても、チューブ１５とハウジング２が導 通しにくくなる。すなわち、丸のこ機１の使用者に対し電気的安全性を向上させ ている。 A conventional portable electric tool will be described with reference to FIGS. 3 to 5, taking a circular saw as an example. FIG. 3 is a front view of the circular saw machine 1, 5 is a circular saw blade driven by a motor, 6 is a base serving as a reference plane during cutting, and 7 is a saw cover for covering the circular saw blade 5. FIG. 4 is a rear view of the circular saw 1, 2 is a metal housing containing a motor, 3 is a tail cover that covers the rear opening of the housing 2, and 8 is a motor cooling air provided on the tail cover 3. A wind window 4 for sucking air into the housing 2 is a screw for fixing the tail cover 3 to the housing 2. FIG. 5 is a partial cross-sectional view of the housing 2, where 18 is a bearing chamber of the housing 2 that holds a bearing on the tail cover 3 side of an armature (not shown) that constitutes the motor, 10 is a stop plate, 11 is a brush holder, and 12 is a motor. The constituent stator 13 is a brush terminal. The brush holder 11 is composed of an insulating tube 14 and a conductive tube 15. The stator 12 and the brush holder 11 are electrically connected by a brush terminal 13. The stop plate 10 is for increasing the creepage distance L between the housing 2 and the brush terminal 13. The stop plate 10 makes it difficult for the tube 15 and the housing 2 to pass through even if chips generated during processing are sucked through the wind window 8 and adhere to the tubes 14 and 15. That is, the electrical safety for the user of the circular saw 1 is improved.

上記した従来技術の欠点は、ストッププレート１０を組込む時に、ブラシホル ダ１１に矢印Ｂ方向から組込みできない、すなわち、組立性が悪いという欠点が あった。 本考案の目的は、上記した欠点を改善し、組立性を向上させることである。 The above-mentioned drawback of the prior art is that when the stop plate 10 is assembled, it cannot be incorporated into the brush holder 11 in the direction of the arrow B, that is, the assemblability is poor. An object of the present invention is to improve the above-mentioned drawbacks and improve the assemblability.
【０００４】[0004]
上記した本考案の目的は、ハウジングの軸受室外周部に嵌合するよう、一対の ストッププレートを一体にした絶縁プレートにすることにより達成される。 The above-mentioned object of the present invention is achieved by forming an insulating plate having a pair of stop plates so as to be fitted to the outer peripheral portion of the bearing chamber of the housing.
【０００５】[0005]
上記のように構成した絶縁プレートを用いる場合、絶縁プレートをハウジング 軸受外周部に一方向より嵌合させて取付ければ良い。この際、従来のようにスト ッププレートを保持する必要がなく、組立性が向上する。 When the insulating plate configured as described above is used, the insulating plate may be fitted and attached to the outer peripheral portion of the housing bearing in one direction. At this time, it is not necessary to hold the stop plate as in the conventional case, and the assembling property is improved.
【０００６】[0006]
本考案実施例を図１、図２に示す。図１は上記した左右一対のストッププレー ト１０を一体に成形した絶縁プレート１９である。該絶縁プレート１９にはブラ シホルダ１１のチューブ１５と嵌合する穴２０を左右に設け、更にハウジング軸 受室外周部１８に嵌合する穴２１を設けてある。このような絶縁プレート１９を 組立るには、図２に示す如く、絶縁プレート１９をハウジング軸受外周部１８を ガイドするよう矢印Ａ方向に突当るまで組込み、その後ブラシホルダ１１を矢印 Ｂ方向からハウジング２に組込めば良い。このように組立ることにより、絶縁プ レート１９が簡単にチューブ１５に取付く。 An embodiment of the present invention is shown in FIGS. FIG. 1 shows an insulating plate 19 in which the pair of left and right stop plates 10 described above are integrally formed. The insulating plate 19 is provided with holes 20 on the left and right for fitting with the tubes 15 of the brush holder 11, and further with holes 21 for fitting on the outer peripheral portion 18 of the housing shaft receiving chamber. In order to assemble such an insulating plate 19, as shown in FIG. 2, the insulating plate 19 is assembled until it abuts in the direction of arrow A so as to guide the housing bearing outer peripheral portion 18, and then the brush holder 11 is inserted from the direction of arrow B in the housing. It should be incorporated in 2. By assembling in this way, the insulating plate 19 is easily attached to the tube 15.
【０００７】 この際、絶縁プレート１９はネジ止め等の固定がいらない。なぜならば、矢印 Ｄ方向の動きはハウジング軸受室外周部１８により規制され、矢印Ｅ方向の動き はブラシホルダ１１のチューブ１５により規制されるためである。At this time, the insulating plate 19 does not require fixing such as screwing. This is because the movement in the arrow D direction is regulated by the housing bearing chamber outer peripheral portion 18 and the movement in the arrow E direction is regulated by the tube 15 of the brush holder 11.
【０００８】[0008]
本考案によれば、ブラシホルダの導電部とハウジング間の鉛面距離を大きくす る一対のストッププレートを一体成形した絶縁プレートとしたので、ブラシホル ダ周囲の組立が簡単になり組立性が向上する。 According to the present invention, the pair of stop plates that increase the vertical distance between the conductive portion of the brush holder and the housing are integrally formed as an insulating plate, so that the assembly around the brush holder is simplified and the assemblability is improved. .
