［０００３］[Industrial Field of Application] The present invention relates to a composite contact strip material that is a material for contact members such as relays, switches, and connectors. [0002] [0002] Conventionally, as shown in FIG. 2, a tape-shaped contact material is attached to the upper surface of one end of a strip-shaped spring material (hereinafter simply referred to as spring material) 1 as one of composite contact strip materials which are materials for the above-mentioned applications. (hereinafter simply referred to as contact material) 2 is resistance welded using a projection 3 provided on its lower surface, or the contact material 2 is welded to the upper surface of one end of the spring material 1 using a material (
For example, there are some welded (spot welded, seam welded, percussion welded, etc.) with a CuNi alloy, etc.) interposed therebetween. [0003]

［０００５］[Problems to be Solved by the Invention] By the way, in the composite contact strip material 5.5' mentioned above, since the projection 3 and the material 4 with good bonding properties are placed on the spring material, the total contact height is It was just that much more expensive. In addition, since only the projection 3 portion of the composite contact strip material 5, which is made by resistance welding the contact material 2 to the spring material 1 at the projection 3, will melt at the projection 3, the spring material 1 may break or crack when the contact material is manufactured using this. There were times when I did something like that. [0004] Therefore, the present invention provides a composite contact strip material in which the contact material is attached to a spring material without using projection or materials with good bonding properties, thereby reducing the total height of the contact and increasing the bonding strength of the bonded portion. That is. [0005]

［０００７］[Function] As described above, in the composite contact strip material of the present invention, the end surfaces of the contact material and the end surfaces of the spring material are joined by electron beam welding, so that the height from the bottom surface of the spring material to the top surface of the contact material is , the height of only the contact material is smaller than the total contact height of the conventional composite contact strip material by the thickness of the material with good projection and bonding properties and the thickness of the spring material.
The total contact height is significantly reduced, and a compact contact member can be manufactured. Furthermore, since the end faces of the contact material and the end faces of the spring material are joined by electron beam welding as described above, the joint strength is high. Therefore, when using contact members manufactured using this method, the joints will not break or crack.
The spring characteristics of the spring material are not impaired. [0007]

［００１０］[Example] An example of the composite contact strip material of the present invention will be explained with reference to the drawings.As shown in Fig. 1, the width is 3 mm and the thickness is 0.65 mm.
The contact material 2a made of 13% by weight of AgCd0 mm has a width of 3
One side end surface of the contact material 2 bonded to the base material 2b made of 13% Cu-Ni with a thickness of 0.15 mm and a width of 15 mm and a thickness of 0.15 mm. One side end surface of the spring material 1 is butted against each other and joined by electron beam welding 6. [0008] On the other hand, an example of a conventional composite contact strip material will be explained with reference to a diagram.As shown in FIG. 2, a contact material 2a made of AgCd013 wt. A contact material 2 bonded to a base material 2b made of 15 mm of Cu-Ni 13% is connected to a projection 3 of a wire of 0.1 mm radius provided in the middle of its lower surface.
One end of a spring material 1 made of phosphor bronze and having a width of 20 mm and a thickness of 0.15 mm is resistance welded to the upper surface. [0009] Comparing the dimensions of the composite contact strip material of the embodiment and the conventional example configured as described above, it is found that the composite contact strip material 5 of the conventional example has a total contact height of 95 mm + α (contact material 2 and spring The composite contact strip material 7 of the example has a total contact height of 0.8 mm and a width of 18 mm, making it more compact. It can be seen that In addition, when the bonding strength between the contact material 2 and the spring material 1 was measured for the composite contact strip material 7 of the example, it was found to be 18 kg/m.
It was high at m2~22 kg 7 mm2 and stable with little variation. When the contact member manufactured using this method was used in a relay, the joint did not break or crack, and the spring characteristics of the spring material were not impaired. [0010]

ある。[Effects of the Invention] As described above, the composite contact strip material of the present invention has a significantly lower total contact height than the conventional composite contact strip material in which the contact material is attached to a spring material, so that it is possible to manufacture a small contact member. Therefore, it is possible to downsize relays, switches, connectors, etc. In addition, in the composite contact strip material of the present invention, the end face of the contact material and the end face of the spring material are joined by electron beam welding, and the joint strength is high. Therefore, the contact member manufactured using this material will not break at the joint part during use. It does not crack and the spring characteristics of the spring material are not impaired.
