BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of connecting an insulation-coated wire to an armature terminal for connecting an insulation-coated wire to a terminal supported by an armature.

[0002]

2. Description of the Related Art In an armature of a magnet generator, as shown in FIGS. 3 and 4, an insulating resin is provided on each salient pole 1a radially provided on the outer periphery of an armature core 1 made of laminated steel plates. An armature coil 3 is wound via an insulating bobbin 2 made of The armature coil 3 is usually formed by winding an insulating coated wire made of an enamel-coated copper wire coated with enamel as an insulating coating. The terminal wire 3a of the insulation-coated wire forming the armature coil 3 is the insulation bobbin 2
Is connected to one end of a rod-shaped terminal 4 penetrating through the armature core 1 and insulated and supported by the insulating bobbin 2 with solder 5. The other end of the terminal 4 is led out to the opposite side of the armature core 1 as shown in FIG. 4, and the core end 6a of the lead wire 6 is wound around the other end of the terminal 4 and connected by soldering 5. There is.

Conventionally, the terminal wire 3a made of an enamel-coated copper wire is connected to the terminal 4 by burning the enamel coating, which is the insulating coating of the terminal wire 3a, with an alcohol lamp flame and rubbing the portion with sandpaper or the like. This is done by removing the coating film, winding the exposed copper wire portion around the terminal 4, and then soldering 5 onto it.

[0004]

However, in such a conventional method of connecting an insulating coated wire to an armature terminal, the enamel coating, which is the insulating coating of the terminal wire 3a, is burnt with a flame of an alcohol lamp and then the Since there is an operation of removing the coating by rubbing the portion with sandpaper or the like, there has been a problem that all must be done manually. Also,
In the conventional method, there are variations in the removed portion of the insulation coating,
There was a problem that the quality of the connection part was not stable.

It is an object of the present invention to provide a method for connecting an insulation coating wire to an armature terminal which enables connection work without special removal work of the insulation coating.

SUMMARY OF THE INVENTION The present invention is an improved method of connecting an insulated wire to an armature terminal for connecting an insulated wire to a terminal supported by an armature.

Further, the present invention improves a method of connecting an insulation covered wire to an armature terminal for connecting a terminal wire of an insulation covered wire forming an armature coil to a terminal supported by an armature. It is a thing.

In the method of connecting an insulation-coated wire to an armature terminal according to the present invention, the insulation-coated wire is locked to the terminal while the insulation coating is still attached. After the locking portion of the insulating coated wire is burned with the flame of the burner , the melted brazing material is attached to the locking portion.

In the present invention, to lock an insulation-coated wire on a terminal means to wind the insulation-coated wire around the terminal, to pass the insulation-coated wire through the hole of the terminal, and to bend the tip of the insulation-coated wire passing through the hole and pull it out. It refers to a state in which, for example, when temporarily stopped, the positional relationship between them is prevented from shifting.

[0010] In the present invention, the operation of burning portions that engage the insulation coated wire to the terminal, the line in the flame of the burner (torch)
U

As the brazing material, it is preferable to use a brazing material having a higher melting point (for example, a melting point of 700 ° C. or more) than solder such as gold, silver, phosphorous copper, brass and platinum.

According to the method of the present invention, the connecting work can be performed without specially removing the insulating coating of the insulating coated wire. Therefore, the connection work can be automated.

In particular, when the locking portion where the insulation-coated wire is locked at the terminal is burned by the flame of the burner, the locking portion is burned at a high temperature and the insulating coating becomes ash, and the ash blows out the flame of the burner. Since the core wire is exposed by being blown off by pressure, a special work of removing the insulating coating is unnecessary. In this state, the brazing material having a high melting point melted by the flame of the burner is attached and brazed, so that the connection work can be automated.

1 and 2 show an example of an embodiment of a method of connecting an insulating coated wire to an armature terminal according to the present invention, and FIG. 1 shows an implementation state of the method of this example. 2 is a longitudinal sectional view showing an armature of a magneto generator in which a connecting portion is formed by the method of this example. The parts corresponding to those in FIGS. 3 and 4 described above are denoted by the same reference numerals.

In this example, as shown in FIG.
The terminal wire 3a, which is an insulation-coated wire made of an enamel-coated copper wire and which constitutes the armature coil 3, is wound and locked with the insulation coating attached. This terminal line 3a
After burning the locking part of the burner (torch) 8 with a flame 9, a brazing material 10 having a high melting point (for example, a melting point of 700 ° C. or more) such as gold, silver, phosphorous copper, brass, platinum, etc. Are melted and adhered to form the brazed connection portion 11.

According to such a method, the connecting work can be performed without specially removing the insulating coating of the insulating coated wire. That is, the terminal wire 3 of the insulation coated wire is connected to the terminal 4.
When the locking part that locks a is baked, the locking part is burned at a high temperature and the insulating coating becomes ash, and the ash is blown off by the blowing pressure of the flame 9 of the burner 8 to expose the core wire. Therefore, the work of removing the special insulating coating is unnecessary. In this state, the high melting point brazing material 10 melted by the flame 9 of the burner 8
Will be attached and brazed. Therefore, the connection work can be automated.

In this connection method, as shown in FIG. 2, the core wire end portion 6a of the lead wire 6 can be connected to the other end of the terminal 4 in the same manner. In this case, the lead wire 6 is locked to the terminal 4 by passing the insulating coated wire portion of the lead wire 6 through the hole of the terminal 4 and bending the tip of the insulating coated wire portion passing through the hole to prevent the lead wire 6 from coming off. . Even if the insulation coating of the insulation coating wire portion is a synthetic resin, it is burned at a high temperature by the flame 9 of the burner 8 to turn the insulation coating into ash, and the ash is blown off by the blowing pressure of the flame 9 of the burner 8, Since the wire is exposed, no special work of removing the insulation coating is required. In this state, burner 8
The high melting point brazing material 10 melted by the flame 9 is attached and brazed.

In the above example, the terminal 4 is the insulating bobbin 2
And the armature core 1 are penetrated, the terminal 4 may be fixed to the insulating bobbin 2.

[0019]

According to the method for connecting an insulating coated wire to an armature terminal according to the present invention, the insulating coated wire is locked to the terminal while the insulating coating is still attached, and the locking position of the insulating coated wire the after baking in the burner flame, so by attaching brazing material melted in locking position to form a brazed connection portion, the insulating coating by baking flame burners and ash
And the ash was blown off by the blowout pressure of the burner flame.
Core wire is exposed and brazing material is adhered to that location.
As a result, a connecting portion can be formed , and the connecting work can be performed without specially removing the insulating coating of the insulating coated wire. For this reason, the connection work can be automated, and the manufacturing cost can be reduced and the quality can be stabilized.
