はさみ、加圧すると同時に通電し溶接していた。(Prior art and issues) For the purpose of stabilizing multi-point contact in sliding contacts used in trimmers, potentiometers, encoders, etc., a multi-wire bundle sliding brush, so-called multi-wire, is made by bundling a large number of ultra-fine wires and welding them to a spring material. Conventionally, in order to manufacture a brush, a multi-wire bundle 3 and a material 4 were sandwiched between upper and lower electrodes I and 2 as shown in FIG. 2, and the welding was carried out by applying pressure and electricity at the same time.
また溶接強度の安定化の為に、第２図に示す如く合材に
凸部５（プロジェクション）を設けて溶接していた。Furthermore, in order to stabilize the welding strength, welding was performed by providing a projection 5 on the composite material as shown in FIG.
しかしいずれの方法においても多線束と接触する電極の
摩耗が著しく寿命が短く、また安定した溶接強度が得ら
れないという問題があった。However, in either method, there are problems in that the electrodes that come into contact with the multi-wire bundle are extremely worn, resulting in a short service life, and stable welding strength cannot be obtained.
この原因を追求したところ、加圧時多線束と点接触応力
集中による変形と、そこへ通電されることによる発熱と
あいまって電極が摩耗することによることが判明し、こ
の知見にもとづき本発明がなされたものである。When the cause of this was investigated, it was found that the electrode was worn out due to deformation due to multi-wire bundle and point contact stress concentration when pressurized, and heat generation due to electricity being applied to the electrode.Based on this knowledge, the present invention was developed. It has been done.

るものである。(Function) According to the electrode for manufacturing a multi-wire bundle sliding brush of the present invention configured as described above, since the multi-wire bundle and the electrode are in surface contact, the pressing force is dispersed and it is difficult to deform, and when energized, The amount of heat generated by the current is also reduced, and therefore the wear of the electrodes is suppressed.
なお、電極面の凹状溝の深さは、線径の１／１０〜２１
５が好ましく １７１０未満だと凹状溝の効果がなく、
また２１５を超えると凹状溝の加工が難しくなるもので
ある。The depth of the concave groove on the electrode surface is 1/10 to 21 of the wire diameter.
5 is preferable, and if it is less than 1710, the concave groove has no effect,
Moreover, if it exceeds 215, it becomes difficult to process a concave groove.

．． A table '+A4 with a projection 5 having an arcuate cross section of 2 mm is placed at a depth of 0.02 mm and a curve radius of 0;04 m.
An electrode provided with a concave groove 6 having the same arcuate cross section as the line shape of m is used as the upper electrode 7 and brought into contact with the east side of the multi-wire, a flat electrode is used as the lower electrode 2, and the multi-wire bundle 3 and the base material 4 are sandwiched,
], a multi-wire bundle sliding brush was obtained by applying a pressure of 5 kg and simultaneously applying electricity and welding.
一方、従来例として、平坦な」二部電極１とした以外は
、実施例と同様にして多線束摺動ブラシを得た。On the other hand, as a conventional example, a multi-wire bundle sliding brush was obtained in the same manner as in the example except that a flat two-part electrode 1 was used.

での交換であった。However, the results shown in the table below were obtained regarding the number of welds (electrode replacement frequency) and welding strength until the electrode on the side that comes into contact with the multi-wire bundle (the two-part electrode) was replaced (electrode replacement frequency). The electrode on the side that comes into contact with the base material (lower electrode) was replaced every 1000 pieces.
ここで、溶接強度は線各々１本の溶接強度で合計１００

れた。As is clear from this result, in the conventional example, the upper electrode had to be replaced every 100 pieces, but in the example, the lifespan is five times longer, up to 500 pieces, and it is stable. A multi-wire bundle sliding brush with welding strength was obtained.
これはひとえに多線束と接触する側である上部電極に線
形状と同一の断面円弧状の凹部溝を設けたことにより、
電極摩耗が抑えられた結果に他ならない。This is due to the fact that the upper electrode, which is the side that comes into contact with the multi-wire bundle, has a concave groove with an arcuate cross section that is the same as the wire shape.
This is the result of suppressed electrode wear.
