[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electron generator of a magnet generator, and relates to an improvement in a structure for fixing terminals of a plurality of coil wire rods which respectively constitute a plurality of phases of an emitter coil. The present invention relates to a device effectively used for generating electricity from a magnet generator installed in a two-wheeled vehicle or a general-purpose engine.

2. Description of the Related Art As a magnet generator mounted on a two-wheeled vehicle or a general-purpose engine, a plurality of electron-generating coils for generating electromotive force are radially arranged, and a plurality of permanent magnets forming field poles. The rotor is arranged in an annular shape, and the rotor is rotated outside the emitter to cause each permanent magnet to relatively cut the magnetic field of each emitter coil. Some are configured to get power.

[0003] As an electron generator used in this rotor abduction type magnet generator, there is one provided with a three-phase electron generating coil.
There is one disclosed in Japanese Patent No. When this is applied to a three-phase delta connection, the result is as follows.

In this case, the coil wire of the electronic coil of each phase is sequentially wound on the plurality of radially arranged salient pole portions by skipping over the electronic coils of the other phase, and the winding start terminal is The winding ends of the coil wire material of the phase generating coil will be respectively connected. First, the winding start end of the first phase coil wire is inserted into the varnish glass tube together with the winding end end of the third phase coil wire. The winding start end of the second phase coil wire is inserted into the silicon varnish glass tube together with the winding end end of the first phase coil wire. The winding start end of the third phase coil wire is inserted into the silicon varnish glass tube together with the winding end end of the second phase coil wire.
At this time, the winding start end of the first-phase coil wire rod and the winding end end of the third-phase coil wire rod inserted into the varnish glass tube are the salient pole portion and the third winding start portion of the first-phase coil wire rod. The remaining four terminals, which were pulled out from between the winding end salient poles of the phase coil wire and were inserted into the two silicon varnish glass tubes, were the salient poles of the winding ends of the second phase coil wire. It is drawn out from between the winding pole end and the salient pole portion of the third phase coil wire. Then, the coil wire rod inserted in the silicon varnish glass tube is entangled with the coil wire rod inserted in the varnish glass tube to be temporarily fixed. After that, the coil is impregnated with varnish, and the varnish is heated and hardened to fix the coil.At this time, the varnish penetrates into the varnish glass tube and hardens, and the bundling portion is in the temporary fixing state described above. It becomes a fixed state from. The ends of the coil wire rods drawn out in this way are connected and connected to three external lead wires, and the connection terminals are covered with an insulating tube previously inserted into the external lead wires. become.

[0005]

However, in the electron emission of the above-mentioned magnet generator, when the winding start end of the coil wire of each phase is pulled out together with the winding end end of the coil wire of another phase, each coil end is pulled out. Since it is necessary to draw the wire between the predetermined salient pole portions, the number of assembling steps increases. Further, since the drawn-out portion of each coil end is bound, it is necessary to mount a varnish glass tube or a silicon varnish glass tube in order to improve the reliability of insulation between the phases of the bound portion. The score increases. Moreover, it is necessary to securely fix the binding portion, and it is sufficient to use a varnish glass tube for all three, but in consideration of workability in connection with an external lead wire in a subsequent process, two varnishes may be treated with varnish. The use of a silicon varnish glass tube that does not solidify complicates parts management and assembly work.

It is an object of the present invention to provide an electronic generator for a magnet generator capable of securely fixing a coil wire without using a protective tube such as a varnish glass tube or a silicon varnish glass tube.

When the winding end terminals are wound around the winding start terminals of the three coil wire rods as described above, next,
Since this assembly is passed through a heating furnace and the respective coil wire rods 11, 21 and 31 as self-bonding wires are self-bonding,
Each coil is integrally solidified. Thereafter, the ends 14, 24, and 34 of the wound-up bundling portion are connected to three external lead wires (not shown), and each terminal is connected as shown in FIG. 3 (b). As shown in the figure, the three-phase delta connection is established. Then, each connection portion is covered with an insulating tube that has been passed through an external lead wire in advance, and wiring is performed in a predetermined layout. At this time, the binding portions that are oriented in the axial direction can be laid down, but the fused electric wire does not hinder the bending unlike the conventional varnish-cured varnish glass tube.

As described above, according to this embodiment, the winding start end of each coil wire is pressed and fixed to each salient pole portion by the winding to each salient pole portion, and the winding end end of each coil wire is also secured. Since it is fixed by entwining each of the fixed winding start ends with each other, it is not necessary to consider the insulation between each phase of the binding part, and the winding start end and winding end end of each coil wire can be fixed. There is no need to use a protective tube such as a glass varnish tube. Therefore, the number of parts can be reduced, and the work of inserting the winding start end and the winding end end of the coil wire into the protective tube such as the glass varnish tube can be omitted. be able to.

Further, since it suffices to wind each winding end end around the winding start end of each coil wire rod fixed to each salient pole portion, the winding work of the winding start end and winding end end of each coil wire rod Can be halved. Moreover, since the winding start end and the winding end end of each coil wire are securely fixed to the core, it is possible to reliably prevent the coil wire from jumping out or breaking due to vibration of electrons generated by the magnet generator. You can

Furthermore, the work of connecting the external lead wire to the ends of the binding parts around which the winding start end and the winding end end of the coil wire are wound can be carried out in a relatively free state of each binding part. Therefore, the connection work can be easily performed.

By using the self-bonding wire for the coil wire, the coil can be solidified as a whole, so that the entire generator of the magnet generator can be robustly constructed and the winding of each coil wire can be performed. At the beginning, it is possible to strengthen the fixed state of the terminal with each salient pole portion, and further, it is possible to omit the solidification step of the entire electron emission of the magneto-generator by applying the varnish.

[0032]

As described above, according to the present invention,
Since the coil wire can be securely fixed without using a protective tube such as a varnish glass tube or a silicon varnish glass tube, it is possible to reduce the number of parts and assembling work, and to increase the productivity of the magnet generator's electronic generation. Can be improved.
