Description of the Related Art Sliding brush pieces used in trimmers, potentiometers, etc. are so-called multi-wire type brush pieces, as shown in FIG. 5, in order to increase the reliability and stability of electrical contact. It is composed by. In this brush piece manufacturing method, a so-called bus bar in which a large number of sliding wires pre-aligned and bundled are arranged at regular intervals is welded, then cut, and the tip contact portion is bent into a semicircular shape to be formed. .

なり易いという問題がある。According to such a conventional technique, since the strands are thin wires having a diameter of about 0.08 mm, the strands are aligned and focused, and the straightness of the strands and the bending of the tip contact portion cause the strands to bend. There is a problem that some of them tend to be broken or the tips are scattered and uneven.

It is characterized by being made into a brush piece.

FIG. 1 is an explanatory view of a thin wire wound in a circle, and FIG. 2 is a perspective view of a brush piece. A thin wire made of 30WT% Ag-40WT% Pd-30WT% Cu with a diameter of 0.08 mm was wound multiple times in a coil shape with a diameter of 3 mm (6 times in this example) to form a continuous body 1. After welding the surrounding portions 2 facing each other, a symmetrical portion deviated from the welding portion was cut as a cutting portion 3 to obtain two brush pieces 4.

例と同様形状に曲げ加工を行った。It should be noted that the cutting point may be any point within a range of 90 ° with the welding point, and the welding point does not have to be the exact symmetrical position facing each other. Quality inspection was performed on 500 brush pieces thus obtained, and the results are shown in Table 1. At the same time, as a comparative example, six thin wires of 0.08 mm in diameter made of 30 WT% Ag-40 WT% Pd-30 WT% Cu similar to those in the above-described example were aligned and focused by a conventional technique, and a thickness of 0.2 mm,
The base of a bus bar made of 80 WT% Cu-20 WT% Ni having a width of 0.5 mm and a length of 1 mm was welded and then cut, and the tip contact portion was bent into a shape similar to that of the above-mentioned embodiment.

On the other hand, the brush piece of the conventional example has a non-uniform tip and a fine wire is dropped off, and is of a quality having an unstable element.

In this case as well, the peripheral symmetrical portion is welded. Then, by setting the symmetrical portion deviated from the welding portion 2 as the cutting portion 3, two brush pieces 4 were obtained, and the same inspection result as above was obtained.
