本発明は、小型モータの整流子外局に摺接する刷子接点
の刷子板材を作る摺動接点材料の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sliding contact material for making a brush plate material of a brush contact that slides into contact with a commutator outer station of a small motor.
従来より小型モータの整流子外周に摺接する刷子接点の
刷子板材を作る摺動接点材料として洋白(Cu54−5

という欠点があった。Conventionally, nickel silver (Cu54-5
81. Nil&5-19.5. Although nickel silver has been used, it has the disadvantages that it tends to form ridges, has high contact resistance and becomes unstable due to the oxidized M, and has poor abrasion resistance.

の摺動接点材料を提供せんとするものである。The present invention has been made to overcome these drawbacks, and aims to provide a nickel silver-based sliding contact material that has low and stable contact resistance and improved wear resistance.
本発明の摺動接点材料は、洋白に、その組成比を変える

0.5〜5重量%添加して成るものである。The sliding contact material of the present invention is made by adding a total of 0.5 to 5% by weight of at least one of B, Ge, Si, and TI to nickel silver without changing its composition ratio.

The reason for adding 5 parts by weight is to suppress the oxidation of Cu and prevent the oxidized Cu from becoming unstable due to its high contact resistance. At the same time, the purpose is to improve the abrasion resistance. If the weight is less than α5, there is no effect, and if it exceeds α5, the springiness of the brush wire will deteriorate.
次に本発明による摺動接点材料と従来の摺動接点材料に

すような結果を得た。Widths of 0.0 mm were made from the sliding contact material of the embodiment of the present invention and the conventional sliding contact material having the component compositions shown in the left column of the table with edges.
5 wg, 0.15 m thick brush plate material pipe cut into length 10 cm As shown in the above figure, the brush plate material 2 of the brush contact 3 is made by holding one brush plate material 2.
A contact piece 1a consisting of -CulQ weight % was brought into sliding contact with the outer periphery of a commutator l of a small motor with a diameter of 10 wm and a length of 6 times, vertically facing each other, under the test conditions described below. A commutator rotation test was performed, and the brush plate material 2 of the brush contact 3
The wear amount and contact resistance were adjusted and the results shown in the right column of the table below were obtained.

Cuより酸化しにくいB、Si。Test conditions Voltage: 24 VS, Current: DCl 00 mA, Commutator rotation speed: 2800 rpm% Commutator rotation time: 500 hours, Brush contact O contact crab 10 was compared to the conventional brush contact brush as shown in the table above. The amount of consumption of the plate material is 40 to 50μ
On the other hand, the wear of the brush plate material of the brush contact point in the example was significantly reduced by 1. It can be seen that it has excellent wear resistance. Further, while the conventional brush plate material had a probe resistance of 1 to 2 Ω, the contact resistance of the brush plate material of the example was 0.75 to 0.85 Ω, which was found to be extremely low and stable. This simply means that the brush plate material in the example is
B and Si are more difficult to oxidize than Cu.
Ge、TIが添加されて摺動中Cuの酸化が抑制されて
、酸化Cuの生成量が減少しているからに他、ならない
。This is because the addition of Ge and TI suppresses the oxidation of Cu during sliding, reducing the amount of Cu oxide produced.

。As described above in detail, the sliding contact material of the present invention is made of German silver and B.
, 8j, Ge, and TI are added to suppress the oxidation of Cu and reduce the amount of oxidized Cu, so the brush plate material of the brush contact made with this has a low sliding contact material and stable wear resistance. It has the excellent effect of significantly improving
