バーである。 FIG. 1 is a schematic diagram showing a structure for connecting a lead wire of an aluminum-wound transformer and a conductor passing through a bushing according to the prior art. As shown in the figure, a copper wire 5 which is connected to an aluminum winding 1 and which connects an aluminum lead wire 2 and a conductor 4 passing through a bushing 3 has copper crimp terminals 6 at both ends thereof. 7 is provided. Among these, the copper crimp terminal 6 is bolted to the conductor 4, and the copper crimp terminal 7 is the surface of the aluminum plate 8 whose outermost layer is tin-plated after zinc and copper have been replaced (the surface shown by diagonal lines in the figure). is connected by bolts. Further, the unplated surface of the aluminum plate 8 is welded to the lead wire 2 by aluminum welding. In the figure, 9 is an aluminum welding point, 10 is an insulating oil, and 11 is a tank cover.

であつた。 However, in this conventional technique, not only expensive copper wire 5 is used, but also an aluminum plate 8 plated to prevent electrolytic corrosion between dissimilar metals has to be used, which increases the cost. He was inviting me. Furthermore, since the aluminum plate 8 is used, the connection structure for connecting the copper wire 5 and the lead wire 2 is complicated.

この結果、総合的に見てメリツトの少ないもので
ある。 Therefore, in order to avoid using the expensive copper wire 5 and to simplify the connection structure, an aluminum wire is used instead of the copper wire 5. That is, since the aluminum wire can be directly welded to the lead wire 2 by aluminum welding, the aluminum plate 8 is unnecessary, and the connection structure can be simplified. However, when an aluminum wire is used in air, a non-conductive oxide film is formed on the surface of the aluminum wire. Therefore, as the crimp terminal used to connect the aluminum wire to the conductor 4 passing through the bushing 3, an expensive copper-aluminum crimp terminal containing an antioxidant must be used. Therefore, if an aluminum wire is used instead of the copper wire 5, the connection structure can be simplified, but a copper-aluminum crimp terminal, which is about 10 times more expensive than a conventional copper crimp terminal, must be used. Even if an aluminum wire, which is cheaper than the copper wire 5, is used, the overall cost will be high.
As a result, it has little merit overall.

経済的メリツトが大である。 In this embodiment, Alumitsu (trade name) manufactured by Nippon Aluminum Co., Ltd. is used as the copper-aluminum solder 15. This aluminum reliably connects aluminum and dissimilar metals (such as copper, brass, zinc, iron, and stainless steel), which are generally considered difficult to connect. Aluminum contains 25-35% zinc, 10-15% cadmium, 30-45% tin,
It is composed of 2-7% silver and 2-7% indium, and requires a special flux when used. The strength of the soldered part with aluminum is about 3 times that of lead-tin solder.
It's double. Listing the various properties of Alumitsu here, the specific gravity is 8.2, the solidification and melting point is 280-310℃, the specific electrical resistance is 0.0693Ω/mm 2 /m, the monopolar potential (based on a saturated calomel electrode) is -0.996mV, and the electrical conductivity ( Universal standard annealed copper as 100%) 25, brazing temperature 300-350
°C, brazing material tensile strength 14.76Kg/mm 2 , brazing material elongation
6.90%, brazing metal hardness 42.90Hv. In this embodiment, since the copper-aluminum solder 15 is soldered at the boundary between the aluminum wire 12 and the copper crimp terminal 14, the aluminum wire 12 in this area is not exposed to air and a non-conductive oxide film is formed. No occurrence occurred, and the aluminum wire 12 and copper crimp terminal 1
The connection strength with 4 is improved. That is, in general,
If an aluminum wire is crimped using a copper crimp terminal, an oxide film on the aluminum or a creep phenomenon of the aluminum due to the difference in materials occurs, making it impossible to maintain the function of the connection point.In contrast, in this example, the aluminum wire 12 and copper crimp terminal Since copper-aluminum solder (aluminum solder) 15 that can connect dissimilar metals called terminals 14 is used, the connection can be made reliably without producing an oxide film or creep phenomenon. In this way, reliable electrical and mechanical contact can be made using the copper crimp terminals 14, which are available in large quantities on the market, and the inexpensive aluminum wires 12.
The economic benefits are great.
