【考案の詳細な説明】
本考案は断路器若しくは接地装置等の開閉器の
ブレードの改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the blade of a switch such as a disconnector or a grounding device.

性からも上記の如くブレードも銅材またはアルミ
ニウム材で形成されている。 Generally, a switch rotates a blade having a movable contact at its tip, and performs opening/closing operations by moving the movable contact toward and away from a fixed contact. Since the movable contact is usually made of copper or aluminum, the blade to which the movable contact is connected is also made of copper or aluminum. In other words, since the movable contact and the blade serve as current-carrying paths, their connections must be maintained in a good state of connection.Also, in order to prevent electrolytic corrosion, the blade is also made of copper or aluminum as mentioned above. It is formed of.

で実用に至つていない。 On the other hand, since the above-mentioned blade needs to have sufficient mechanical strength to withstand the impact force during opening/closing operations, if it is made of copper or aluminum only without using reinforcing materials, the blade will have a larger current carrying capacity than the required one. As a result, it had the disadvantage of being expensive. For this reason, while the blade is made of copper or aluminum material with a size that satisfies the current carrying capacity, it is also possible to secure the blade with a reinforcing member made of hot-dip galvanized iron material to satisfy the mechanical strength. However, in this case, reinforcing members are required, which not only complicates the structure, but also
This has the disadvantage that assembly work is also complicated. It is also conceivable to use the reinforcing member with hot-dip galvanizing on the surface of the above-mentioned iron material as it is as a blade, but in this case, heat generation and Problems such as electrolytic corrosion occur and it is difficult to obtain a good connection, so it has not been put to practical use.
そこで本考案は上記従来技術の欠点に鑑み、ブ

供することを目的とする。 Therefore, in view of the above-mentioned shortcomings of the prior art, the present invention has been developed by forming the blade of iron material and applying molten aluminum plating to the surface of the blade, thereby maintaining the connection part with the movable contact in a good condition. The purpose is to provide a switch blade that has a simple structure and is inexpensive.

処理を行つて接続されている。 An embodiment of the present invention will be described in detail below with reference to the drawings. In the figure, reference numeral 1 denotes an angle-shaped blade, which is made of iron and whose surface is plated with molten aluminum. A movable contact 2 made of copper is fastened to the tip of the blade 1 with bolts 4 and nuts 5 through an aluminum-copper mating plate 3. That is, the copper portion of the aluminum-copper laminated plate 3 is connected to the movable contact 2.
The aluminum portion of the aluminum-copper laminate plate 3 is in contact with the blade 1. In this case, the connection surfaces between the copper part of the aluminum-copper laminated plate 3 and the movable contact 2 are connected directly or by silver plating on both surfaces, and the aluminum-copper laminated plate The connection surface between the aluminum portion 3 and the blade 1 is connected by aluminum-aluminum compounding.

技術として確立されているので、実用上の問題が
生ずることはない。 In the above configuration, since the blade 1 itself is made of iron material, it not only has excellent mechanical strength but also is very inexpensive. In addition, since the surface of the iron material is plated with molten aluminum, it not only has excellent corrosion resistance, but also is connected to the movable contact 2 made of copper material via the aluminum-copper laminated plate 3. Since the metals of the same type are connected to each other, a good connection can be obtained without fear of electrolytic corrosion. In addition, the molten aluminum plating on the surface of the iron material when forming the blade 1 and the aluminum plating when connecting the aluminum part of the aluminum-copper laminated plate 3 and the blade 1 are applied.
All aluminum compounding treatments are well established as conventional techniques, and therefore do not pose any practical problems.

接続部を得ることができる。 In the above embodiment, the movable contact 2 is made of copper material, but if it is made of aluminum, the movable contact 2 and the blade 1 may be connected by performing an aluminum-aluminum compound treatment. For example, a good connection can be obtained as in the above embodiment.
また上記実施例ではブレード１はアングル形状

ある。 Further, in the above embodiments, the blade 1 is described as having an angular shape, but it goes without saying that a shape such as a flat plate or the like may be used without any problem as long as the mechanical strength is satisfied.

ことができる。 As described above in detail with the embodiments, according to the present invention, since the blade itself is made of iron material, it not only has superior mechanical strength compared to the blade made of copper material or aluminum material in the prior art. The price is also very low. In addition, since the surface of the iron material is plated with molten aluminum, it has excellent corrosion resistance, and the connection part with the movable contact made of copper or aluminum material can be maintained in good condition. Obtainable.
