本発明は、インレイ型の電気接点帯材の製造方法に関す
るものてある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing an inlay type electrical contact strip.
従来の電気接点帯材にはベース材と接点とを一体化した
所謂クラッド材と称するものがあるが、その中で第１図
のようなインレイ型の電気接点帯材もかなり使用されて
いる。Among conventional electrical contact strip materials, there is a so-called clad material that integrates a base material and a contact, and among these, an inlay type electrical contact strip material as shown in FIG. 1 is also widely used.
このインレイ型の電気接点帯材は、第２図に示す如くベ
ース材１に切削加工により溝２を形成し、その後溝２に
合つた寸法の接点材３を嵌め込み、シーム溶接して製造
したものである為、接点材３とベース材１の溝２の底に
おける境界面４（第１図参照）は良く溶接されているが
、溝２の両側壁における境界面５は全く溶接されていな
いものであつた、従つてかかる電気接点帯材にて作られ
た電気接点は、使用中に前記接点材３が剥れるという欠
点があつて、接点としての信頼性が甚だ低いものであつ
た。本発明の目的は、接点材がベース材との境界面より
決して剥れることのないインレイ型電気接点帯材の製造
方法を提供せんとするものて、以下にその実施例を図面
によつて説明すると、先ず第３図に示す如くベース材６
と該ベース材６よりも硬い接点材３を重ね合せて圧接し
、然る後圧延加工を行つて第４図に示す如く接点材３’
をベース材６’中に埋没させる。かように本発明の製造
方法では、接点材３にベース材６よりも硬い材料のもの
を用いるので、圧延加工により接点材３’がベース材６
’に抱へられる形となり、強固な接合が得られるもので
ある。尚、接点材３とベース材６の圧接時の重ね合せ位
置は第３図に示される寸法でもつてΠ■１以上、厚さに
ついてはΠ＝一丁、板巾比についてｗ１Ｈ’ １はｗ■
一丁、さらに圧延比については■＝Ｐ下であることが好
ましい。This inlay-type electrical contact strip material is manufactured by forming a groove 2 in a base material 1 by cutting as shown in Fig. 2, and then fitting a contact material 3 of a size that matches the groove 2 and seam welding. Therefore, the interface 4 at the bottom of the groove 2 between the contact material 3 and the base material 1 (see Figure 1) is well welded, but the interface 5 on both side walls of the groove 2 is not welded at all. Therefore, electrical contacts made from such electrical contact strip materials had the disadvantage that the contact material 3 peeled off during use, and had extremely low reliability as a contact. An object of the present invention is to provide a method for manufacturing an inlay-type electrical contact strip material in which the contact material never peels off from the interface with the base material. Then, first, as shown in FIG.
and the contact material 3, which is harder than the base material 6, are superimposed and pressed together, and then rolled to form the contact material 3' as shown in FIG.
is buried in the base material 6'. Thus, in the manufacturing method of the present invention, since the contact material 3 is made of a harder material than the base material 6, the contact material 3' is rolled into the base material 6.
', which creates a strong bond. The overlapping position of the contact material 3 and the base material 6 during pressure contact is Π■1 or more with the dimensions shown in FIG.
It is preferable that the rolling ratio is less than ■=P.
以上の説明で判るように本発明の製造方法によれば、接
点材がベース材に抱えられて両者がその境界部で強固に
接合され、決して接点材がベース材より剥れることのな
いインレイ型電気接点帯材を容易に製造できるという優
れた効果がある。As can be seen from the above explanation, according to the manufacturing method of the present invention, the contact material is held by the base material and the two are firmly joined at the boundary, and the contact material is an inlay type that never separates from the base material. This has the excellent effect that electrical contact strip material can be easily manufactured.
また本発明の製造方法は、従来のインレイ型電気接点帯
材の製造方法におけるベース材の溝切り加工が省略され
ているので、手間がかからず作業性に優れたものである
。Further, the manufacturing method of the present invention does not require grooving of the base material in the conventional method of manufacturing inlay-type electrical contact strips, so it is time-consuming and has excellent workability.
