本発明は、小型モータの整流子外Ｗ４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 the commutator outside W4 of a small motor.
従来よシ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としてＢｅＬ ６〜２．０

生成によ）＃触抵抗が高く不安定になシ、壇た耐消耗性
が劣下するという欠点があった。BeL 6 to 2.0 is used as a sliding contact material to make the brush plate material of the brush contact that slides into contact with the commutator outer station of a conventional small motor.
Be-Cu, which is made up of heavy weight and the remainder is Cu, has been used, but in Be-Co, Cu oxidizes, and due to the formation of oxidized Cu), the contact resistance is high and it becomes unstable, and the resistance is very low. It had the disadvantage of being less consumable.
本発明は、かかる欠点を解消すべくなされたもので接触
抵抗を低く安定させ且つ耐消耗性を向上させたＢｅ−Ｃ
ｕ系の摺動Ｗ！虜材料を提供せんとするものである。The present invention was made in order to eliminate such drawbacks, and is a Be-C with low and stable contact resistance and improved wear resistance.
U-type sliding W! The purpose is to provide materials that will captivate people.
本発明の摺動接点材料は、Ｂｅ１．６〜２，０ 重量
嘔。The sliding contact material of the present invention has a Be of 1.6 to 2,0.
残部Ｃｕよシ成るＢｅ−Ｃｕに、その組成比を変える仁

０．５〜５重量％添加して成るものである。It is made by adding a total of 0.5 to 5% by weight of at least one of B, Si, Ge, and TIO to Be-Cu, the balance of which is Cu, without changing the composition ratio.

る。In such original #jO sliding assault material, Be-Cu
Adding at least one type of K%B, 8i, Ge, TI (7) to a total of 0.5 to 5% rA is because by adding these elements, which are less likely to oxidize than Cu, Cu This is to suppress the oxidation of Cu, prevent high contact resistance and instability caused by Cu oxide, and improve wear resistance.
If it is less than 0.5 weight %, there is no effect of Fi, and if it exceeds 5% by weight, the spring properties of the Jii11 child plate material will deteriorate.

5w, 0.15m thick brush board material with length 10wK
As shown in the cut diagram above, a brush contact 30 formed by holding one brush plate material 2 has a thickness of 0.2 m on the outside of the brush plate material 2t-1.
Three contact pieces 1a made of oAg-Cu 10 wt. A rotation test was conducted on the commutator, and the wear amount and contact resistance of the brush contacts 30 and the brush plate material 2 were measured. Got the results.

Contact Crab of Time Brush Contact 1 of As is clear from the above table, the amount of consumption of the brush plate material of the brush contact of the conventional example was 25 to 40μ, while the amount of consumption of the brush plate material of the brush contact of the example was 18μ It can be seen that the wear resistance is significantly reduced at ~20μ, indicating excellent abrasion resistance. MakuContrary to the conventional brush plate material, which has a contact resistance of 1 to 20, 6 points,
It can be seen that the contact resistance of the brush plate materials of Examples is extremely low and stable, ranging from 0.7 to 0.80. This is simply because the brush plate material of the example is made of B or Si, which is less susceptible to oxidation 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.

ある。The sliding contact material of the present invention detailed above is Be-C1
By adding B, Si, Ge, and TI to 1, the oxidation of Cw can be suppressed and the amount of Cu oxide produced can be reduced. It has the excellent effect of being stable at a low level and significantly improving wear resistance.
