Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for connecting ultrafine wires.

[0002]

2. Description of the Related Art The present invention relates to the connection of ultrafine wires of .phi.50 .mu.m. Until now, such ultrafine wires were rare and connection was not necessary. On the other hand, φ100μ
Various methods have already been used for thick wires of about m or more,
The (1) fusion welding method, (2) pressure welding method, (3) brazing method and the like have been put to practical use.

(1) includes arc welding, electron beam and laser beam, and (2) includes resistance welding, ultrasonic welding, cold pressure welding and the like.

FIG. 3 shows a case where the conventional welding method is applied to an ultrafine wire having a diameter of about 50 μm. As shown in the figure, the fine wires 4 fixed to the magnet sheets 3 and 3a on the alignment bases 2 and 2a provided on the pair of movable fine movement stages 1 and 1a, respectively, are The fine movement stage 1a on one side was moved to the side of the fine movement stage 1 on one side, the ultrafine wires 4 were butted against each other, silver brazing 5 was applied, and heating was performed by the heating device 6 for connection. In addition, in FIG.
Is a flat plate, and 8 and 8a are magnets.

[0005]

The above welding method is applied with φ50μ.
When applied to an ultra-fine wire of about m, the ultra-fine wire has extremely low rigidity, and as shown in FIG. 3, the connection point is significantly bent or curled, and it is difficult to apply the pressure required for crimping. Also, the core alignment required for fusion welding and brazing cannot be performed.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a method of connecting ultrafine wires which enables connection of ultrafine wires.

[0007]

The above-mentioned object is to provide grooved cylinders adjacent to the alignment bases on a pair of fine movement stages that are movably opposed to each other, and set them at the same height as these alignment bases. After winding the ultrafine wire around the groove of the grooved cylinder and fixing the ultrafine wire with the magnet sheet, move the other side fine movement stage away from the one side fine movement stage to pull and break the fine line between the grooved cylinders. After straightening, the fine movement stage on the other side is moved to the fine movement stage on the one side after this straightening, and the straightened ultrafine wires are butt-aligned, and then silver brazing is applied to apply the fine wire. Achieved by connecting comrades.

[0008]

With the provision of the above means, the ultrafine wire to be connected can be straightened.

[0009]

EXAMPLES Next, the present invention will be specifically described by way of examples.

[Embodiment 1] FIGS. 1 and 2 show an embodiment of the present invention. Since the same parts as those in the past are designated by the same reference numerals, the description thereof will be omitted. In this embodiment, the grooved cylinders 9 and 9 are adjacent to the positioning bases 2 and 2a on the pair of fine movement stages 1 and 1a that are movably opposed to each other.
a is provided, and the ultrafine wire 4 is wound around the grooves of the grooved cylinders 9 and 9a having the same height as those of the alignment bases 2 and 2a, and the ultrafine wire 4 is fixed by the magnet sheets 3 and 3a, and then the fine movement of the other side is performed. The stage 1a is moved away from the fine movement stage 1 on one side to pull and break the fine wire 4 between the grooved cylinders 9 and 9a to straighten it, and after this straightening, the fine movement stage 1a on the other side is Move to the fine movement stage 1 side,
After the straightened ultrafine wires 4 were butt-aligned with each other, silver brazing 5 was applied to connect the ultrafine wires 4 together. By doing so, the ultrafine wire 4 to be connected is straightened, the centering becomes possible, and the ultrafine wire connecting method that enables the connection of the ultrafine wire 4 is obtained. be able to.

That is, the fine wires 4 connected to the grooved cylinders 9 and 9a adjacent to the positioning bases 2 and 2a on the fine movement stages 1 and 1a are wound around each other or separately. The grooves of the grooved cylinders 9 and 9a are at the same height as the alignment bases 2 and 2a. Next, the ultrafine wire 4 is fixed by the magnet sheets 3 and 3a, and the fine movement stage 1a on the other side is moved away from the fine movement stage 1 on the one side. By performing this operation, the ultrafine wire 4 is pulled and ruptured and straightened.
The straightened ultrafine wires 4 are butted and aligned with each other, and then silver braze 5 is applied to connect them.

By using the method of connecting the ultrafine wires having a diameter of about 50 μm or less, the following effects can be obtained.

(1) By pulling and breaking the ultrafine wire, the ultrafine wire is straightened and alignment becomes possible.

(2) An extra fine wire can be connected by applying silver brazing to the centering portion and heating it.

[0015]

As described above, according to the present invention, the grooved cylinders are provided adjacent to the positioning bases on the pair of fine movement stages which are movably opposed to each other, and are set at the same height as these positioning bases. After winding the ultrafine wire around the groove of the grooved cylinder and fixing the ultrafine wire with the magnet sheet, move the other side fine movement stage away from the one side fine movement stage to pull and break the fine line between the grooved cylinders. After straightening, the fine movement stage on the other side is moved to the fine movement stage on the one side after this straightening, and the straightened ultrafine wires are butt-aligned, and then silver brazing is applied to apply the fine wire. Since the comrades are connected, the ultrafine wire to be connected is straightened and the centering is possible, and the ultrafine wire connection method that enables the connection of the ultrafine wire can be obtained. ..
