本発明は銀、錫等の接点材料１を銅、アルミニ
ウム板等の基板２にレーザー溶接する方法に係
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for laser welding a contact material 1 such as silver or tin to a substrate 2 such as a copper or aluminum plate.
レーザー光４の照射よるレーザー溶接法による
と、第１図の如くレーザー光４を直接に接点材料
１に照射すると接点となる表面を損傷するので好
ましくない。そこで第３図の如く一般に基板２の
裏面側からレーザー光４を照射する方法をとつて
いる。しかしながら接点を基板２の表裏面の同じ
位置に溶接せんとするとレーザー光４を表面より
照射せざるをえず、この際、第２図の如く、側面
より照射すると充分な溶接強度がえられない欠点
があつた。 According to the laser welding method using the irradiation of the laser beam 4, it is not preferable to directly irradiate the contact material 1 with the laser beam 4 as shown in FIG. 1 because it will damage the surface that will become the contact. Therefore, as shown in FIG. 3, a method is generally used in which laser light 4 is irradiated from the back side of the substrate 2. However, if the contacts are to be welded to the same position on the front and back surfaces of the board 2, the laser beam 4 must be irradiated from the surface, and in this case, as shown in Figure 2, if the laser beam 4 is irradiated from the side, sufficient welding strength cannot be obtained. There were flaws.
本発明は上記欠点を除去せんとするものであ

け、他方、接点材料１に前記凸部５に嵌合する凹
部７を設け、該接点材料１を基板２に、凸部５を
凹部７に嵌合せしめて仮止めし、かつ両者の嵌合
部に側面よりレーザー光４を照射することを特徴
とする接点のレーザーの溶接法である。 The present invention aims to eliminate the above-mentioned drawbacks, and its gist is to provide the substrate 2 with a convex portion 5, and to provide the contact material 1 with a concave portion 7 that fits into the convex portion 5. This is a contact laser welding method characterized by fitting the material 1 to the substrate 2 and the convex part 5 to the concave part 7 for temporary fixing, and irradiating the fitted part of both with a laser beam 4 from the side.
以下本発明を第４図乃至第７図に示す各実施例
により説明する。 The present invention will be explained below with reference to embodiments shown in FIGS. 4 to 7.
即ち、本発明にあつては、まず基板２に、相互
に隣接する凸部５及び凹部６を設ける。 That is, in the present invention, first, a convex portion 5 and a concave portion 6 that are adjacent to each other are provided on the substrate 2.
一方接点材料１に前記凸部５及び凹部６に嵌合
する凹部７及び凸部８を設ける。 On the other hand, the contact material 1 is provided with a recess 7 and a projection 8 that fit into the projection 5 and recess 6.
上記接点材料１を、基板２に凸部５及び凹部６
を凹部７及び凸部８に嵌合せしめて仮止めする。 The contact material 1 is applied to the substrate 2 in the convex portions 5 and concave portions 6.
are fitted into the concave portion 7 and the convex portion 8 and temporarily secured.
つづいて嵌合部の側面よりレーザー光４を照射
する。 Next, laser light 4 is irradiated from the side surface of the fitting part.
以上の如く第４図に示す実施例においては接点
材料１に凸部５及び凹部６を設け、基板２に凹部
７及び凸部８を設けて両者が相互に嵌合するよう
にしている。 As described above, in the embodiment shown in FIG. 4, the contact material 1 is provided with a convex portion 5 and a concave portion 6, and the substrate 2 is provided with a concave portion 7 and a convex portion 8 so that they fit into each other.
第５図に示す実施例においては接点材料１に凹
部７を、基板２に凸部５のみを設けて両者を嵌合
せしめている。嵌合部の側面よりレーザー光４を
照射して溶接するのは上記例と同様である。 In the embodiment shown in FIG. 5, the contact material 1 is provided with a recess 7, and the substrate 2 is provided with only a protrusion 5, and the two are fitted together. As in the above example, welding is performed by irradiating the laser beam 4 from the side surface of the fitting part.
第６図に示す実施例におては、接点材料１及び
基板２の両者は基本的に第４図に示す実施例と同
じ構造をとるが、接点材料１を表面のみを銀１１

料とし材料特性に基づく溶接の容易性を促進せし
めている。 In the embodiment shown in FIG. 6, both the contact material 1 and the substrate 2 basically have the same structure as in the embodiment shown in FIG.
The back surface is made of copper 12, which is the same material as the substrate 2, and promotes ease of welding based on the material properties.
而して本発明によれば、嵌合部において接点材
料１と基板２とが重なり合つているので該部分に
レーザー光４を照射せしめることにより充分な強
度をもつレーザー溶接ができるのである。 According to the present invention, since the contact material 1 and the substrate 2 overlap at the fitting portion, laser welding with sufficient strength can be performed by irradiating this portion with the laser beam 4.
