Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alternator. In particular, the present invention relates to an alternating current generator having a stator and a rectifier, in which the structure of the connection of the neutral wire among the coil terminals of the stator is improved.

Conventionally, neutral wire bonding of stator coils of an alternating current generator has been carried out in a structure in which the neutral wire is twisted and the twisted portions are bonded by soldering or the like. However, such conventional technology requires a molding process to concentrate each neutral wire in one place when joining, and has the disadvantage of poor workability.

In view of the above circumstances, an object of the present invention is to provide an alternator with a structure that simplifies the work of joining the stator coil neutral wire.

In order to achieve the above object, in the present invention, each wire ring terminal of the stator is extended while maintaining its positional order, and one of the terminals that will become a neutral wire is connected through a conductive joining auxiliary material. The configuration is such that they are joined.

As a bonding auxiliary material with conductivity, for example, copper plate,
Alternatively, a metal with good conductivity such as an aluminum plate can be used. If such a bonding auxiliary material is used, bonding of the neutral wires can be achieved by separately bonding each neutral wire to the bonding auxiliary material. As a result, the same characteristics as those obtained by joining wires together can be obtained, and workability can be significantly improved compared to the conventional method.

An embodiment of the present invention will be described below with reference to FIG.

The main components of this alternator are a rectifier 1 and a stator 5.
and a bonding auxiliary material 4 for the neutral line. In this configuration, each wire ring terminal of the stator 5 is extended while maintaining its position order, and the terminal that becomes the neutral wire 9 is joined via the conductive joining auxiliary material 4. I have to.

More specifically, the specific configuration of this embodiment is as described below.

The rectifier 1 is provided with a rectifier connection terminal 2 to which a rectifier wire 3 from the stator 5 is connected. The neutral line bonding auxiliary material 4 is provided with a neutral line connection terminal 8 for connecting the neutral line 9. The lines from each coil end of the stator 5, that is, the neutral line 9 and the rectifying line 3, are extended while maintaining their position order. The connection of the rectifier wire 3 to the terminal 2 and the connection of the neutral wire 9 to the terminal 8 are performed by appropriate means such as soldering. The stator 5 is composed of a stator core 7 and a wire ring 6 wound around the stator core 7.

In FIG. 1, for ease of understanding, the rectifier 1, neutral wire bonding auxiliary material 4, and stator 5 are drawn separately.
In order to show the separated state, the intermediate part between the neutral wire 9 and the rectifying wire 3 is shown by a broken line. In the actual structure, the rectifier 1 and the neutral wire bonding auxiliary material 4 are integrated into one body by tightening screws, etc., while providing electrical insulation. That is, the joining auxiliary material 4 is integrally attached to the rectifier 1 by being fixed to the rectifier 1 by insulating bolts or other appropriate means while maintaining insulation properties and a constant distance from the rectifier 1.

In FIG. 2, the AC generator of FIG. 1 is converted into an electric circuit, and a capacitor 10 is added. The coil 12, rectifier 11, and coil connection point 13 in FIG. 2 correspond to the coil 6, rectifier 1, and rectifier connection terminal 2 in FIG. 1, respectively. Further, the neutral point 14'n in FIG. 2 corresponds to the portion constituted by the neutral line joining auxiliary material 4 and the neutral line connecting terminal 8 in FIG.

According to this embodiment, the line alignment process for each terminal upon neutral line joining can be accomplished by simply forming the terminals into a simple straight line. Therefore, the work of crossing the rectifier wire and the neutral wire as in the conventional method becomes essential, and the workability of the neutral wire joining process is greatly improved. In fact, according to this embodiment, the workability can be improved by about 40% compared to the conventional method.

FIG. 3 shows another embodiment of the invention. In the example of FIG. 1, the neutral wire bonding auxiliary material 4 is fixed by appropriate fixing means.
In the example shown in FIG. 3, the neutral line auxiliary material 15 is integrated with the rectifier 1 as shown in the figure.
It is a separate object. In this example, the neutral wire bonding aid 15 is located between the rectifier 1 and the stator 5, and the rectifier wire 3 is inserted into the hole formed in the neutral wire bonding aid 15 through the insulating ring 16.
It is configured so that it can be passed through with a . Such joining auxiliary material 1
5, a neutral wire 9 is appropriately connected to the neutral wire 9.

In addition to the effect of improving workability, this embodiment also has the effect of improving the vibration resistance of the wiring because the support interval between each wiring is shortened.

As described above, in the alternating current generator of the present invention, each wire ring terminal of the stator is extended while maintaining its positional order, and the terminal that becomes the neutral wire is joined via a conductive joining auxiliary material. Because of this structure, the line alignment work for joining the neutral wire is extremely easy, and it is also possible to simply extend it in a straight line, which has the effect of significantly improving work efficiency.

It should be noted that, as a matter of course, the present invention is not limited to the illustrated embodiments.
