Abstract

PROBLEM TO BE SOLVED: To solve the problems in which, since a contact material is manufactured by a sintering method and a contact is manufactured by brazing or welding the contact material to a base material, it is not possible to make a contact point long, it is required to produce contact materials one by one, it takes much time and effort to complete a contact, and it is difficult to manufacture contacts of various shapes.SOLUTION: The manufacturing method of a contact comprises processes of: producing a composite contact material by applying a base material surface of a desired shape with either a 1 to 99 mass% Ag-W coating or a 1 to 99 mass% Ag-WC coating so as to keep both sides remained; and continuously producing a plurality of pieces by cutting the composite contact material.

Description

本発明は、Ａｇ−ＷもしくはＡｇ−ＷＣの接触子の製造方法および接触子に関する。   The present invention relates to a method for producing an Ag-W or Ag-WC contactor and a contactor.

従来より、重負荷領域の接点の材質として、Ａｇ−ＷもしくはＡｇ−ＷＣが適用されている。これらは、焼結法で接点材を製造し、その接点材を、台材にろう付けまたは溶接することによって接触子を製造している（例えば、特許文献１参照、特許文献２参照、特許文献３参照）。   Conventionally, Ag-W or Ag-WC has been applied as the material for the contacts in the heavy load region. In these, a contact material is manufactured by a sintering method, and the contact material is manufactured by brazing or welding the contact material to a base (see, for example, Patent Document 1, Patent Document 2, and Patent Document). 3).

しかし、上記の従来技術によると、長尺の接点材を製造するためには、巻き取り機構をもつ大型の炉などを用いる必要があり、初期投資費用が多大であり、経済的でない。これにより、接点の長尺化が難しく、接点材を１個ずつ作製してから、接点材を１個ずつ台材に接合する必要があった。そのため、接触子の完成に多くの手間を要するという問題があり、さらに、多様な形状の接触子を容易に製造しにくいという問題がある。そこで本発明は、接点材と台材とを１個ずつ接合することなく、接触子を容易に製造することを目的とする。   However, according to the above prior art, in order to manufacture a long contact material, it is necessary to use a large furnace having a winding mechanism, and the initial investment cost is great, which is not economical. As a result, it is difficult to lengthen the contacts, and it is necessary to join the contact materials one by one to the base material after producing the contact materials one by one. Therefore, there is a problem that a lot of labor is required to complete the contact, and there is a problem that it is difficult to easily manufacture contacts having various shapes. Accordingly, an object of the present invention is to easily manufacture a contact without joining a contact material and a base material one by one.

本発明は、ＣｕまたはＣｕ合金等の導電性のある長尺台材に１〜９９質量％Ａｇ−Ｗもしくは１〜９９質量％Ａｇ−ＷＣのコーティングを連続的に施すことにより、台材に接点材料を直接形成する。このようにした長尺接点材料をプレス加工もしくは切断加工等の所定の加工により接点子に形成する。   The present invention provides a contact with a base material by continuously applying a coating of 1 to 99 mass% Ag-W or 1 to 99 mass% Ag-WC on a conductive long base material such as Cu or Cu alloy. Form the material directly. The long contact material thus formed is formed on the contact by a predetermined process such as pressing or cutting.

なお、コーティング方法は、プラズマ溶射、ガス溶射、高速フレーム溶射、コールドスプレー法等の溶射でのコーティング、空中や液中での断続的な放電、パルス等の放電によるコーティングおよびＰＶＤ（Ｐｈｙｓｉｃａｌ Ｖａｐｏｒ Ｄｅｐｏｓｉｔｉｏｎ）、ＣＶＤ（Ｃｅｍｉｃａｌ Ｖａｐｏｒ Ｄｅｐｏｓｉｔｉｏｎ）等の蒸着法によるコーティングである。   The coating methods include plasma spraying, gas spraying, high-speed flame spraying, cold spraying and other thermal spraying coatings, intermittent discharge in the air and liquid, coating by discharge such as pulses, and PVD (Physical Vapor Deposition). , Coating by a vapor deposition method such as CVD (Chemical Vapor Deposition).

以上のようにした製造方法によると、長尺の台材に接点材を連続的に直接形成することができるために、長尺の複合接点材料を作製することが可能となる。   According to the manufacturing method as described above, since the contact material can be continuously formed directly on the long base material, it is possible to produce a long composite contact material.

また、切断加工もしくはプレス加工等の所定の加工を施すことによって従来必要であった作製工程を削減して固定接触子および可動接触子を容易に作製することが可能となる。   In addition, by performing a predetermined process such as a cutting process or a press process, it is possible to easily manufacture a fixed contact and a movable contact by reducing a manufacturing process that has been conventionally required.

さらに、コーティングおよび台材の長さ、幅、厚さ等は調整可能であるために任意の形状の接触子を製造することが可能となる。   Furthermore, since the length, width, thickness, and the like of the coating and the base material can be adjusted, it is possible to manufacture a contact having an arbitrary shape.
