【発明の詳細な説明】 〔技術分野〕 この発明は密封型接点装置の製法に関する。[Detailed description of the invention] 〔Technical field〕 The present invention relates to a method for manufacturing a sealed contact device.
電磁開閉器、あるいは、パワーリレーなどに用いる接点
装置として、水素を含む混合ガスが封入されている容器
内に、可動・固定両接点を備えた密封型の接点装置が開
発された。封入された水素は、その熱伝導率が大きく、
アークを冷却する作用が強いので、接点開離時に発生す

、接点の消耗が少なくなり、接点寿命を延ばすことがで
きる。窒素は水素を含むことにより起こる絶縁性の低下
を補う。また、密封型の接点装置は、接点の酸化が進み
難いという利点もある。A sealed contact device has been developed that is used in electromagnetic switches or power relays, and has both movable and fixed contacts in a container filled with a mixed gas containing hydrogen. Enclosed hydrogen has high thermal conductivity,
Since it has a strong arc cooling effect, the arc generated when the contacts open can be extinguished in a short time. Therefore, wear of the contacts is reduced, and the life of the contacts can be extended. Nitrogen compensates for the decrease in insulation caused by the inclusion of hydrogen. Further, the sealed contact device has the advantage that oxidation of the contact does not progress easily.
この接点装置には、一側に可動接点を有し他側が容器外
に出ている接点端子が可動接点を固定接点と離接させる
方向に移動可能に設けられている。接点端子の移動に伴
い接点離接動作がなされるようになっているのである。In this contact device, a contact terminal having a movable contact on one side and the other side protruding from the container is provided so as to be movable in the direction of bringing the movable contact into contact with and away from the fixed contact. The contact is connected and separated as the contact terminal moves.
この接点端子と容器ノ間は、金属ベローズにより気密に
塞がれている。ベローズと接点端子は、レーザー溶接や
ろう接などの溶接により接合されている。The space between this contact terminal and the container is hermetically sealed with a metal bellows. The bellows and the contact terminal are joined by welding such as laser welding or brazing.
しかしながら、この接点装置は、ベローズと接点端子の

クが短時間で消滅しなくなり、接点消耗が激しくなって
しまう。However, this contact device has a problem in that the vicinity of the joint between the bellows and the contact terminal is easily damaged. This causes a crank to occur in the bellows. The phenomenon of cranking occurs not only during the manufacturing process but also during use. When cracks occur, the sealed state is impaired and the sealed mixed gas leaks. As a result, the arc cannot be extinguished in a short time, resulting in severe contact wear.
この発明は、前記の事情に鑑み、製造工程のみならず、
製造後も、ベローズと接点端子の接合個所まわりの破損
を抑えることができる密封型接点装置の製法を提供する
ことを目的とする。In view of the above circumstances, this invention not only covers the manufacturing process, but also
It is an object of the present invention to provide a method for manufacturing a sealed contact device that can suppress damage around the joint between a bellows and a contact terminal even after manufacturing.
〔発明の開示〕

があるとクラックが生じ易いということを見出した。[Disclosure of the Invention] In order to achieve the above object, the present invention has been developed to investigate the cause of crack occurrence, and as a result, since the bellows is extremely thin, only the bellows melts and melts during welding. It has been found that evaporation tends to cause cracks, etc., and that cracks are likely to occur if there is a gap between the metal bellows (bellow frame) and the contact terminal.

。Based on this knowledge, we continued to study ways to prevent cranking, and as a result, we decided to attach a collar-shaped metal member to the contact terminal by sandwiching the joint part of the metal bellows between them. Therefore, they discovered that if welding was performed from above this metal member, the occurrence of cranking could be significantly reduced, leading to the completion of this invention.

It is movably provided, and the contact is connected/disconnected by moving the contact terminal.

ように組みつける。The bellows 23 of this embodiment is made of Ni (nickel) -
A metal bellows made of a material having a three-layer structure of Cu (copper)-Ni, and having a thickness of 30 μm and having a layer structure formed by electrodeposition, for example, is used. The thickness of the Ni layer is 12 to 14 μm. If the bellows 23 is made only of copper, the strength may not be sufficient, so a Ni layer is provided. A
u (gold) may be used, but it is not practical from a cost standpoint. First, before welding, the contact terminal 21, metal bellows 23, and collar (collar-shaped metal member) shown in FIG. ) 24 are assembled as shown in FIG. 3(b).

ー24があるので、ベローズ23が蒸発飛散しない。し
かも、接点端子21とベローズ23の間は隙間がないの
で、この点でも、クラック発生は抑えられる。This assembly is performed, for example, as follows. The inner diameter of the cylindrical collar 24 is larger than the outer diameter of the joint portion 21a of the contact terminal. One end 2 which is the joining point of the bellows 23
The collar 24 is fitted into the joint portion 21a with the portion 3b in between, and then the collar 24 is caulked. In other words,
Connect the collar 24 to the contact terminal 21 so that the joint 23b of the metal bellows 23 is sandwiched between the contact terminal 21 and the collar 24.
It is applied to the surface. In this state, there is naturally no gap in the part of the metal bellows 23 held down by the collar 24,
It is in close contact with the contact terminal 21. When welding is performed by irradiating the laser LS from above the collar 24, the bellows 23 will not evaporate and scatter at that location because the collar 24 is above the collar 24. Moreover, since there is no gap between the contact terminal 21 and the bellows 23, the occurrence of cracks can also be suppressed in this respect.
カラー24は、NiあるいはNi合金で形成されている
ことが望ましい。The collar 24 is preferably made of Ni or a Ni alloy.

相線であり、A−Cが固相線である。For example, when the material of the collar 24 is Fe (iron)-based,
This Fe and Cu (copper) of the contact terminal 21 are melted. As shown in FIG. 4, this molten alloy of Cu and Fe has a wide solidification temperature range. Therefore, the strain in the first solidified part is added to the unsolidified part, causing cracks in the weld nugget and causing joint failure. In addition, Figure 4 shows
It is an equilibrium state diagram of Cu and Fe, and in the figure, A-B is a liquidus line and A-C is a solidus line.
カラー24の材料が、NiあるいはNi合金である場合
、このNiと接点端子21のCu (銅)が溶融する。When the material of the collar 24 is Ni or a Ni alloy, this Ni and the Cu (copper) of the contact terminal 21 are melted.
CuとNiの溶融合金は、第5図にみるように、凝固温

It is an equilibrium state diagram of Cu and Ni, and in the figure A'-B-
C' is the liquidus line, and A'-D-C' is the solidus line.
カラー24は、接点端子21に被着させる前に焼鈍して

5〜35%であったのが、35〜55%に増加し、溶接
時の歪みがより吸収されやすくなるからである。焼鈍は
、例えば、真空中、60分間、800℃の温度下で加熱
処理によって行う。It is desirable that the collar 24 be annealed before being attached to the contact terminal 21. When annealed, the elongation of collar 24 is 1
This is because it increases from 5 to 35% to 35 to 55%, making it easier to absorb distortion during welding. The annealing is performed, for example, by heat treatment at a temperature of 800° C. for 60 minutes in a vacuum.
この発明は上記実施例に限らない。接点端子へのカラー
の被着方法は、カシメ止め以外の方法であってもよい。This invention is not limited to the above embodiments. The method of attaching the collar to the contact terminal may be other than caulking.
溶接もレーザー溶接以外の溶接方法が用いられてもよい
。接点装置が、図示の構造に限らないことは言うまでも
ない。Welding methods other than laser welding may also be used. It goes without saying that the contact device is not limited to the structure shown.

長くなる。As described above, the method for manufacturing a contact device according to the present invention can suppress damage around the joint between the bellows and the contact terminal not only during the manufacturing process but also after manufacturing. Therefore, the manufacturing yield is improved, the sealed state is maintained for a long period of time, the wear of the contacts is reduced, and the life of the contacts is extended.

,・,+・6, Specification to be amended 7, Contents of the amendment ■ The entire text of the scope of claims column of the specification is corrected as follows. (l) A fixed contact and a movable contact are housed in a container, and a contact terminal having the movable contact on one side and the other side protruding outside the container is a direction in which the movable contact comes into contact with and separates from the fixed contact. The contact terminal is movably provided, and the contact is connected and separated by movement of the contact terminal, and a metal bellows that airtightly closes the gap between the container and the contact terminal is joined to the contact terminal by welding. In addition, in obtaining a sealed contact device in which a mixed gas containing hydrogen is sealed in the container, a collar-shaped metal member is attached to the contact terminal with the metal bellows sandwiched therebetween. There,
