The present invention relates to an improved method of manufacturing a rivet type composite electrical contact. Traditionally, to make a rivet-type composite electrical contact,
A base strip 1 having a rectangular cross section as shown in FIG. Next, this is cut to a required length to form a prismatic cubic composite contact piece 4 as shown in FIG. 1c,
After that, this composite contact piece 4 is processed into a header to form the first
As shown in FIG. d, a rivet-type composite electrical contact 5 having an arcuate contact surface was formed. However, in this method of manufacturing a riveted type composite electrical contact, since the prismatic cubic composite contact piece 4 is subjected to header processing, there is a natural limit to the leg diameter of the resulting riveted type composite electrical contact 5, and the head diameter is generally limited. It is about 1/2 of that. In addition, the outer circumferential shape of the riveted type composite electric contact 5 becomes an ellipse, the tension of the contact material 2' on the top surface of the head becomes uneven, and burrs appear on the periphery of the head, resulting in poor quality riveted type composite electric contacts. This is where the contact point 5 occurs. Furthermore, the mold for header processing is easily damaged, and it is necessary to remove the burrs, which increases the number of man-hours. The present invention was developed in view of the above circumstances, and it expands the range of leg diameters that can be formed into a rivet-type composite electric contact, makes the outer peripheral shape circular, and makes the tension of the contact material on the top surface of the head substantially uniform. A rivet-type composite electrical contact that can be made without any burrs on the periphery of the head, with good quality, and that also eliminates damage to the mold during header processing. The purpose is to provide a manufacturing method. The manufacturing method of the rivet-type composite electrical contact of the present invention is as shown in FIG. A contact strip material 8 is pasted onto the outer surface of the contact strip material 8 using a rolling roll as shown in FIG. A cubic-shaped composite contact piece 10 is formed, and then this composite contact piece 10 is subjected to header processing to form a rivet-type composite electric contact 11 having an arcuate contact surface as shown in FIG. 2d. In the method for manufacturing a rivet type composite electrical contact of the present invention, a T-shaped cubic composite contact piece 10 is made,
Since this is processed into a rivet-type composite electric contact 11 with an arcuate contact surface, the amount of plastic processing is extremely small, so if the amount of plastic processing is increased within the allowable amount of the material, it can be formed. The range of the leg diameter of the rivet type composite electrical contact 11 can be expanded, and there will be no problem even if it is processed to about 1/3 of the head diameter. In addition, the outer circumferential shape of the riveted type composite electrical contact 11 is circular, the tension of the contact material 8' on the top surface of the head is uniform, and there are no burrs on the periphery of the head, resulting in a high quality riveted type composite electrical contact. Electrical contact 1
1. Furthermore, as mentioned above, since the amount of plastic working is small, the die for header processing is not damaged and its durability is improved. Further, as mentioned above, since burrs do not occur, there is no need to remove burrs, thus reducing the number of man-hours. Next, in order to clarify the effects of the method for manufacturing a rivet type composite electrical contact according to the present invention, specific examples and conventional examples thereof will be described. Example As shown in Fig. 2a, a T-shaped piece with a vertical side 7 of 2 mm in height and 0.5 in width was made by extrusion and drawing.
A Cu strip base material 6 with a horizontal side 7' width of 2 mm and a thickness of 1 mm is made, and then the vertical side 7 of this strip base material 6 is placed on the outer surface of the strip base material 6 as shown in Fig. 2b. The composite contact strip material 9 is laminated with a 0.5 mm thick Ag contact strip material 8 using a rolling roll, and then this is cut into a length of 1 mm to form a T-shaped cube as shown in Fig. 2c. This composite contact piece 10 was then processed into a header to form a head diameter of 3 mm, a head height of 1 mm, a thickness of the contact material of the head of 0.5 mm, and a leg as shown in FIG. 2d. An arc-shaped rivet-type composite electrical contact 11 with a diameter of 1.4 mm, a height of the leg part of 1.5 mm, and a contact surface radius of 7 mm was molded. Conventional example As shown in Figure 1a, vertical
Make base strip 1 with a rectangular cross section of 3.3 mm and 1 mm width.
Next, the contact strip material 2 with a thickness of 0.5 mm is laminated on the upper surface of the base strip material 1 as shown in Fig. 1b to form a composite contact strip material 3, which is then cut into a length of 1 mm to form a composite contact strip material 3.
The composite contact piece 4 is made into a rectangular cubic composite contact piece 4 as shown in Fig. An arc-shaped rivet-type composite electrical contact 5 was molded with a contact material 2' having a thickness of 0.3 mm, a leg diameter of 1.4 mm, a leg height of 1.5 mm, and a contact surface radius of 7 mm. When 100 rivet-type composite electrical contacts of these embodiments and conventional examples were inspected for quality, the results shown in the table below were obtained.

効果がある。[Table] As is clear from the above table, the rivet-type composite electrical contact of the example has an elliptical head shape,
In addition, there were no defective products with burrs on the outer edge of the head or uneven thickness of the contact material on the top of the head.
In other words, in the manufacturing method of the rivet-type electrical contact of the example, no defective products are produced even if the outer diameter of the leg is plastically worked to 1/3 of the outer diameter of the head, and a rivet-type composite electrical contact of good quality can be obtained. It turns out that it can be done. In the above embodiment, a rivet-type composite electrical contact for single-headed contacts is made, but a rivet-type composite electrical contact for double-headed contacts may also be made. In this case, when making the strip base material 6 with a T-shaped cross section, the contact strip material is attached to the outer end surface of the horizontal side 7'. As detailed above, the method for manufacturing a rivet-type composite electrical contact of the present invention involves making a T-shaped cubic composite contact piece, and processing this into a header to produce a rivet-type composite electrical contact with an arcuate contact surface. Since the amount of plastic working is extremely small, and therefore the amount of plastic working can be increased, the range of leg diameters that can be formed can be expanded. In addition, the outer circumferential shape can be made circular, the thickness of the contact material on the upper surface of the head can be made uniform, and the occurrence of burrs on the periphery of the head can be suppressed, thereby obtaining a riveted type composite electrical contact with good quality. be able to. Furthermore, since the amount of plastic working is extremely small, the mold for header processing will not be damaged, contributing to improved durability. Further, as mentioned above, since no burrs are generated, there is no need to remove burrs, which has an excellent effect of reducing the number of man-hours.
