The coil conductor 2 exposed at the end of the coil lead 1 is inserted between a large number of wires 4 exposed at the end of the lead wire 3 and the coil. A brazing material such as hard solder or solder is poured into the part where the conductor 2 rubs, and the coil conductor 2 and the strands 4 of the lead wire 3 are electrically connected to form the conductor connection part 5. . Next, this conductor connection part 5
Then, the strands 4 of the lead wire 3 and the coil conductor 2 on both sides are filled with an insulating compound and sealed to form a filled part 6, which connects the coil lead 1 and the lead wire. In addition to making the difference in diameter between the conductor connection portion 5 and the conductor connection portion 5 gentle, the stepped portion formed around the conductor connection portion 5 is eliminated. After that, a buripreg mica tape is wound around the outer periphery of the filling part 6 formed by filling the insulating compound, or an insulating layer 7 is formed by winding the mica tape while applying epoxy resin to a general mica tape. was formed, thereby insulating the lead wire connection portion 8'. Note that 9 in the figure indicates an exterior portion formed by winding a protective tape around the outer periphery of the insulating layer 7 in order to protect it.
上記したように、従来のコイルと口出線との接続は、回

処理の後に行っていたので、以下に述べるような不具合
があった。As mentioned above, the conventional connection between the coil and the lead wire was performed after the entire coil incorporated in the iron core of the rotating electric machine was vacuum-pressurized and impregnated, which caused the following problems. .
（１）コイルリードを含んだコイル全体に絶縁樹脂を含

部にマイカテ−プを巻回して、加熱硬化を行っているの
で、作業性が悪い。(1) Since the entire coil including the coil lead is impregnated with insulating resin, the insulation properties of the coil are significantly improved. The insulating layer 7 is formed by winding a buri-preg mica tape around the output wire connection part, or by winding the mica tape while applying epoxy resin to a general mica tape, and then performing heat curing or the like. Therefore, in this insulation treatment method, voids are generated inside the insulating layer 7, which causes the insulation to deteriorate. Workability is poor because mica tape is wound around and heat cured.

縁性を低下させる。(2) Since the coil and the lead wire are connected after vacuum pressure impregnation treatment is applied to the entire coil, the coil lead 1 connected to the lead wire is impregnated with insulating resin and becomes flexible. is becoming scarce. For this reason, if the coil lid l is bent in order to connect it to the lead wire, cracks may form in the insulating layer at this portion, reducing the insulation properties of the coil.

くなる。(3) In order to eliminate the above-mentioned problems, simply connect the lead wire to the coil and then vacuum apply insulating resin to the entire coil incorporated in the iron core, including the lead wire connection part. When pressure impregnated, the insulating resin that has permeated into the insulating layer of the coil lead 1 due to the suction effect of the vacuum passes through the continuous gap formed in this part and reaches the lead wire 3.
It penetrates between the strands 4 and hardens. This causes the lead wire 3 to have poor flexibility, making it impossible to smoothly store the lead wire 3 in the casing or to easily pull it out from the terminal box.

る。The present invention mainly solves the above-mentioned problems of the conventional method for connecting a coil and a lead wire, in which the coil and the lead wire are connected after the entire coil incorporated in the iron core of a rotating electric machine is vacuum-pressurized and impregnated. In view of this, we have improved the insulation properties of the lead wire connection part and its surrounding areas, and applied insulation treatment to prevent the flexibility of each part from decreasing, and to improve the workability of connecting the lead wire. This was done with the goal of improving the quality of life.

両者の絶縁を一体にすることである。The means adopted by the present invention to solve the above problems is to connect the coil lead and the lead wire, wrap an insulating tape around the outer periphery of the lead wire connection part to form an insulating layer, and then rotate the coil lead and the lead wire. By impregnating the entire coil built into the iron core of electrical equipment and the lead wire connection part with insulating resin under vacuum pressure,
The purpose is to integrate the insulation of both.

不要となって、口出線の接続のための作業性が高まる。For this reason, the insulating layer formed by wrapping insulating tape around the outer periphery of the lead wire connection part and the coil built into the iron core are impregnated with insulating resin, so that the lead wire connection part and the coil are impregnated together. The insulation of the lead wire connection area is integrated, and the insulation of the lead wire connection area is improved.In addition, it is possible to wrap the lead wire connection area with Bripregmi force tape or apply epoxy resin, which was indispensable in the conventional method. Wrapping of mica tape is no longer necessary, improving work efficiency for connecting lead wires.

できる。After the coil lead and the lead wire are connected, the lead wire connection part is impregnated with an insulating resin integrally with the coil incorporated in the iron core. Alternatively, the brazing material is poured into the conductor connection part where the lead wire and the coil conductor are connected so that there are no continuous gaps along the axial direction over the entire cross section of that part, and the insulating resin is In addition to providing an infiltration prevention section, the outer periphery of the conductor connection part is filled with a filler material by lapping a predetermined length into the sheathing part of the lead wire, so that the raw material of the lead wire is protected during impregnation with insulating resin. Resin will not infiltrate into the line area. Therefore, it is possible to prevent the flexibility of the lead wire from being impaired due to the resin infiltrating and hardening between the strands of the lead wire.

Pour a brazing material such as hard solder or solder from the coil conductor 2 side into the part where the bare wire 4 of the lead wire 3 and the coil conductor 2 are ramped, and then connect the bare wire 4 of the lead wire 3 and the coil conductor 2. The conductor connection portion 5 [the length of which is indicated by (L)] is formed by electrically connecting the
Ll in the diagram! A brazing material is poured into a portion of only the wire 4 and the coil conductor 2 of the outlet vA3 indicated by 2. In particular, in the part of the lead wire 3 where only the strands 4 are present, brazing material is poured so that no continuous gap is created along the axial direction over the entire cross section of that part, and the insulating resin infiltration prevention section (I !

浸入防止区間を設けてもよい。Another method for forming the insulating resin infiltration prevention section is to make the length (L) of the conductor connection part 5 that electrically connects the strand 4 of the lead wire 3 and the coil conductor 2 to a sufficiently long length. An insulating resin infiltration prevention section may be provided by pouring brazing material over the entire cross section of the conductor connection portion 5 so that no continuous gap is formed along the axial direction.

浸入するのを防止するための処置である。The purpose of forming the filling portion 6 on the outer periphery of the conductor connection portion 5, the coil conductor 2 on both sides thereof, and the strands 4 of the lead wire 3 is exactly the same as the conventional method, but in the present invention, the conductor Between the end of the connecting part 5 on the side of the lead wire 3 and the covering part of the lead wire 3, there is a lamp of a predetermined length (the lamp length is y.3). The feature is that the filling part 6 is shaped by filling with an insulating compound (as shown). This is because when the coil conductor 2 and the strands 4 of the lead wire 3 are connected by brazing, the sheathing of the lead wire 3 may be burned out due to the brazing heat. The burnt out part of the covering part or the insufficiently covered part of the end of the lead wire 3 is covered with a filler, and the entire insulating resin is vacuum-pressurized impregnated after the coil lead 1 and the lead wire 3 are connected. This is a measure to prevent resin from infiltrating into the strand 4 of the lead wire 3 from the portion of the strand 4 of the lead wire 3 into which the brazing material has not been poured due to the suction effect of the vacuum.
