本発明は直流電動機のブラシホルダの耐振強度の改良に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improving the vibration resistance of a brush holder for a DC motor.
従来のブラシホルダの構造はブラシの収納部側壁にブラ
シから引出したブラシリード線をガイドする案内溝を設
けており、ブラシの摩耗代を多く確保しようとして案内
溝の長さが長くなり収納部側壁の残った端部か細くなっ
ていた。ブラシは常にブラシスプリングにより押圧され
ており、ブラ（１）
シが摩耗してくると案内溝にガイドされたブラシリード
線が収納部側壁の端部にとどくようになる。The structure of conventional brush holders is that a guide groove is provided on the side wall of the brush storage area to guide the brush lead wire pulled out from the brush.In order to ensure more wear allowance for the brush, the length of the guide groove becomes longer and the side wall of the storage area becomes longer. The remaining end was tapered. The brush is constantly pressed by a brush spring, and as the brush (1) wears out, the brush lead wire guided by the guide groove comes to reach the end of the side wall of the storage section.
ところがブラシを押圧しているブラシスプリングの荷重
が高いこととエンジンから伝わる振動が著しく大きいの
で細くなった収納部側壁の端部を折損するという不具合
が生じていた。However, because the load of the brush spring that presses the brushes is high and the vibration transmitted from the engine is extremely large, there has been a problem in that the narrow end of the side wall of the housing part breaks.
本発明はブラシホルダの振動による折損を防止するため
にブラシホルダを補強し、あわせてブラシリード線の振
動断線をも防止して耐久性を向上させることを目的とし
ている。An object of the present invention is to reinforce the brush holder in order to prevent the brush holder from breaking due to vibration, and also to prevent the brush lead wire from being broken due to vibration, thereby improving durability.
すなわちブラシホルダにブラシの収納部側壁を延長しＵ
字形状にこの収納部側壁の外側へ曲げた補強部と、ブラ
シ収納部側壁から前記補強部の間にブラシから引出した
ブラシリード線を複数箇所でガイドする案内溝とを設け
たものである。In other words, extend the side wall of the brush storage part to the brush holder.
A reinforcing portion bent outward in the side wall of the storage portion in a shape of a letter B, and a guide groove for guiding the brush lead wire drawn out from the brush at a plurality of locations are provided between the side wall of the brush storage portion and the reinforcing portion.
以下本発明を図に示す実施例について説明する。The present invention will be described below with reference to embodiments shown in the drawings.
第１図は本発明のブラシホルダの斜視図である。FIG. 1 is a perspective view of the brush holder of the present invention.

ｆに固定されブラシ２を押圧する。ホルダプレート５は
図示せぬスタータ内部に固定されリベット６でブラシホ
ルダ１を固定する。The brush holder 1 is made of a single conductive plate, and has a reinforcing part 1b which is an extension of the side wall 1a of the storage part in which the brush 2 is stored and is bent to the outside of the side wall of the storage part in a U-shape. It is provided between the storage section side wall 1a and this reinforcing section 1b. In addition, the brush holder 1 has a reinforcing portion 1
A spring hanger 1f is provided on the opposite side of bending b to fix the brush spring 4. Since the storage section side wall 1a and the reinforcing section 1b are provided with the guide groove IC, they have narrowed end portions 1d and le remaining. FIG. 2 is an assembly diagram of the brush holder 1. A brush lead wire 3 is embedded in the brush 2, and this brush lead wire 3 is connected to the 2 by the guide groove IC.
The end is guided at the point and soldered to the holder plate 5. The brush spring 4 has a spiral shape and is connected to the spring hanger 1.
It is fixed at f and presses the brush 2. The holder plate 5 is fixed inside a starter (not shown), and the brush holder 1 is fixed with rivets 6.
コンミテータ７は回転子に設けられ、ブラシ２と摺動す
る。The commutator 7 is provided on the rotor and slides on the brush 2.
次に上記構成においてその作用を説明する。スタータを
長時間使用しているとブラシ２とコンミテータ７が摺動

い。それで端部１ｄを細くして案内溝ＩＣの長さを長く
すればブラシ２の摩耗代を多くとることができる。又、
ブラシリード線３は補強部１ｂがあるためエンジンの振
動が加わって起こる振幅を規制できるので疲労による断
線が防止できる。Next, the operation of the above configuration will be explained. When the starter is used for a long time, the brush 2 and the commutator 7 slide, which causes the brush 2 to wear out and the brush lead wire 3 guided by the guide groove IC to be pushed by the brush (3) and spring 4 into the storage area. Side wall 1a and reinforcement part 1b
reaches the ends 1d and 1e. In this state, brush holder 1
Even if an external force or large vibration is applied to the housing, the external force or vibration will be absorbed by the end 1d of the storage section side wall 1a and the end 1e of the reinforcing section 1b.
Since the brush holder 1 is dispersed and held at different locations, the brush holder 1 will not break. Therefore, by making the end portion 1d thinner and increasing the length of the guide groove IC, the amount of wear of the brush 2 can be increased. or,
Since the brush lead wire 3 has the reinforcing portion 1b, the amplitude caused by the vibration of the engine can be controlled, and breakage due to fatigue can be prevented.
なお本発明の他の実施例として第３図に示すようなもの
がある。収納部側壁１ａから延長した補強部１ｂと案内
溝ＩＣを設けた位置を第１図の実施例と反対にしてもよ
い。つまり本発明のブラシホルダ１はブラシ２の挿入方
向の規制を受けることはない。There is another embodiment of the present invention as shown in FIG. The reinforcing portion 1b extending from the side wall 1a of the housing portion and the guide groove IC may be provided in opposite positions to those in the embodiment shown in FIG. In other words, the brush holder 1 of the present invention is not subject to restrictions on the insertion direction of the brush 2.
以上述べたように本発明によればブラシホルダに設けた
補強部で外力や振動を分散してブラシホルダの折損を防
止でき、ブラシリード線のガイド（４）
