小形モータのブラシ装置は構成の簡素化・小形化を図る
ために、例えば厚さ０．１５ｍｍのベリリウム銅の板材
から導電性帯状ばね板１を打抜き、その帯状ばね板１の
長手両辺に相対向する内向き傾斜辺２，２を設け、その
傾斜辺２，２に角柱状ブラシ３の掛合斜面部４をあり差
し的に掛合させることが行なわれている。[Detailed description of the invention] In order to simplify and downsize the configuration of the brush device for a small motor, a conductive strip-shaped spring plate 1 is punched out of a beryllium copper plate with a thickness of 0.15 mm, for example, and the strip-shaped spring plate is Opposite inwardly inclined sides 2, 2 are provided on both longitudinal sides of the brush 1, and the engaging slope portion 4 of the prismatic brush 3 is engaged with the inclined sides 2, 2 in a dovetail manner.
上記の掛合斜面部４の角度αは傾斜辺２，２の自然形状
開き角度よりも小さく構成されているため、ブラシ３を
ばね板面に沿って第２図矢方向へ移動させると、傾斜辺
２，２は掛合斜面部４により外方へ押し広げられる。Since the angle α of the engaging slope portion 4 is configured to be smaller than the natural opening angle of the slope sides 2, 2, when the brush 3 is moved along the spring plate surface in the direction of the arrow in FIG. 2, 2 are pushed outward by the engaging slope portion 4.
このためブラシ３はその頂面が傾斜辺２，２の弾性復元
力によってばね板平面に押圧され、ばね板１に強固に組
付は保持される。Therefore, the top surface of the brush 3 is pressed against the plane of the spring plate by the elastic restoring force of the inclined sides 2, 2, and the brush 3 is firmly attached to the spring plate 1 and held.
本案はこの種のブラシ装置に関するもので、ばね板１に
対するブラシ３の組付作業を簡単にすることを目的とす
る。The present invention relates to this type of brush device and aims to simplify the work of assembling the brush 3 to the spring plate 1.
この手段として、掛合斜面部４をブラシの対向二面３１
．３１の上下対称位置に形成したものである。As a means for this, the engaging slope portion 4 is connected to the two opposing surfaces 31 of the brush.
．． 31 are formed at vertically symmetrical positions.
第１，２図はブラシ３の両面３１．３１の上下間中心線
Ｘ−Ｘに対して上下対称に台形溝５を形威し、その台形
溝５の上下斜面を掛合斜面部４とした例。Figures 1 and 2 show an example in which a trapezoidal groove 5 is formed vertically symmetrically with respect to the center line XX between the upper and lower surfaces 31 and 31 of the brush 3, and the upper and lower slopes of the trapezoidal groove 5 are used as the interlocking slope portions 4. .
第４図は面３１の上下間中心線Ｘ−Ｘ上にＶ形溝６を形
成して、その上下斜面を掛合斜面部４とした例である。FIG. 4 shows an example in which a V-shaped groove 6 is formed on the upper and lower center line XX of the surface 31, and the upper and lower slopes thereof are used as the engaging slope portions 4.
本案は上記の構成であるから、ブラシ３をばね板１に組
付けるに当り、上下の向きを考える必要がないので、組
付は作業は簡単となり組付けの失敗も生じないものであ
る。Since the present invention has the above-mentioned configuration, there is no need to consider the vertical direction when assembling the brush 3 to the spring plate 1, so that the assembling work is simple and there is no possibility of failure in assembling.
なお、図中７はばね板１の長子一端を直角に折曲げた位
置決め用ストッパ片、８，８は傾斜辺２，２の後部を長
さｌだけ突出させて形成したブラシ抜止め用段差、９，
９は傾斜辺２，２のブラシ挿入側端部に形成したブラシ
挿入ガイド片である。In the figure, 7 is a positioning stopper piece made by bending one end of the long side of the spring plate 1 at right angles, 8, 8 is a step for preventing brush removal formed by protruding the rear part of the inclined sides 2, 2 by a length l, 9,
Reference numeral 9 denotes a brush insertion guide piece formed at the end of the inclined sides 2, 2 on the brush insertion side.
