(Industrial Application Field) The present invention relates to an improvement in a method for manufacturing a rivet type composite contact material. (Prior art and its problems) Conventionally, in order to manufacture riveted composite contact materials,
Base material 1 formed into a rivet mold as shown in Fig. 2a
On the top surface of the plate, Ag-Pd alloy, Pd-Ru alloy,
The contact 2 made of Pt-Ir alloy etc. is connected to the second one using Ag solder.
After brazing as shown in Figure b, the head 3a of this preformed rivet type composite contact material 3 is formed using a punch 6 equipped with a recess 5 having a spherical bottom surface 4 as shown in Figure 2c. A rivet-type composite contact material 7 shown in FIG. 2d was manufactured in this manner. However, in this method of manufacturing a rivet-type composite contact material, when the contact material 2 is brazed to the upper surface of the rivet-type base material 1 with Ag solder as shown in FIG. 2b,
As shown in FIG. 3a, the contact material 2 is obliquely brazed to the rivet type base material 1, and when this is formed with a punch 6 as shown in FIG. 2c, the result is as shown in FIG. 3b. There was a problem in that a riveted composite contact material 7' was produced in which the contact material 2 was stretched diagonally. Furthermore, when the head 3a of the preformed rivet type composite contact material 3 is formed with the punch 6 as shown in FIG. 2c, the center of the upper surface is not processed into a spherical shape but becomes a flat surface as shown in FIG. 2d. There was a problem with 8 remaining. (Purpose of the Invention) The present invention was made to solve such problems, and it is possible to braze the contact material to a rivet type composite material without tilting it, and to prevent a flat surface from remaining on the top surface of the contact material. The object of the present invention is to provide a manufacturing method capable of manufacturing a rivet type composite contact material. (Structure of the Invention) The method for manufacturing a rivet type composite contact material of the present invention includes:
The top surface of the rivet-type base is depressed into a spherical shape, and the top and bottom surfaces of one contact are bulged out into a spherical shape with approximately the same dimensions as the top surface of the base, and then the contact material is brazed on the top surface of the base. Then, the head of this preformed rivet type composite contact material is formed with a punch provided with a recessed portion having a spherical bottom surface. In this way, the method for manufacturing a rivet-type composite contact material of the present invention involves making the top surface of a rivet-type base material into a spherical shape, while making both the upper and lower surfaces of the contact material into a spherical shape with substantially the same dimensions as the top surface of the base material. Because it bulges out, when the contact material is brazed to the top surface of the base material, the contact material can be brazed horizontally and stably without tilting, and the head of the preformed rivet type composite contact material can be attached to the spherical bottom surface. Since the molding is performed using a punch having a concave portion, the bonding surface between the contact material and the base material is substantially flat, and the upper surface of the contact material is spherical, so that no flat surface remains. (Example) An example of the method for manufacturing a rivet type composite contact material of the present invention will be described with reference to the drawings.As shown in Fig. 1a, the head diameter is 2 mm, the thickness is 0.4 mm, the leg diameter is 1.5 mm,
The upper surface of the rivet-type base material 1' made of Ag-Ni 10% by weight with a height of 1.7mm is depressed into a spherical shape with a radius of 4.5mm, and the contact made of Ag-Pd 50% by weight alloy with a diameter of 1.8mm and a thickness of 0.75mm. Both sides of the upper surface of the base material 1' are formed into a spherical shape with a radius of 4.5 mm to have a diameter of 2 mm, a thickness of 0.7 mm at the center, and a thickness of 0.4 mm at the outer edge. Contact material 2' is attached to the top surface using Ag solder as shown in Figure 1b.
The head portion 3'a of this preformed rivet type composite contact material 3' has a spherical bottom surface 4' with a radius of 5 mm as shown in FIG. A rivet type composite contact material 7' shown in FIG. 1d was obtained by molding with a punch 6' having a recess 5' of 0.7 mm and a depth of 0.9 mm at the center. On the other hand, as shown in FIG. 2A, the upper surface of a rivet-type base material 1 made of 10% by weight Ag-Ni with a head diameter of 2 mm, a thickness of 0.35 mm, a leg diameter of 1.5 mm, and a height of 1.7 mm was prepared using the conventional method. A flat plate of Ag with a diameter of 2 mm and a thickness of 0.6
- The contact material 2 made of 50% by weight Pd alloy is brazed with Ag solder as shown in Fig. 2b, and then the head 3a of this preformed rivet type composite contact material 3 is 5 mm radius as shown in Fig. 2c. The rivet-type composite contact material shown in FIG. 2b is obtained by forming the contact material with a punch 6 having a spherical bottom surface 4, a recess 5 having a depth of 0.7 mm on the inner peripheral surface and a depth of 0.9 mm in the center. I got a 7. However, when 100 pieces of each of the rivet type composite contact materials of these examples and conventional examples were quality tested, the results shown in the table below were obtained.

にできる画期的なものと言える。[Table] As is clear from the table above, in the conventional rivet type composite contact materials, 50 out of 100 contacts had a slope, and 20 out of 100 had a flat surface remaining on the top surface of the contact material.
On the other hand, the rivet type composite contact materials of the Examples had no inclination of the contact materials or any flat surfaces remaining on the upper surfaces of the contact materials. (Effects of the Invention) As can be seen from the above explanation, according to the method for manufacturing a rivet-type composite contact material of the present invention, a rivet-type composite contact without tilting of the contact material and without leaving a flat surface on the top surface of the contact material. It has the excellent effect of being able to easily obtain materials, and can be said to be an epoch-making method that can be used as an alternative to conventional manufacturing methods.
