1 is a cross-sectional view of a collector accessory according to the prior art,

2 is a cross-sectional view illustrating a method according to an embodiment of the present invention.

The present invention relates to a method for manufacturing an accessory of an alternator collector or an alternating current starter, and more particularly, to a method for manufacturing an accessory for an automotive alternator collector or an alternating current starter.

Conventional collectors are fitted on the shaft of an alternator and are manufactured by insulating a connection rod made of a conductive material.

1 shows a conventional collector in the manufacturing stage.                         

The illustrated collector comprises two conductive rods 1a and 1b and a frame 2, and also includes a conductive cylindrical linkage 3.

The rods 1a and 1b are generally made of copper and are formed in a flat form with a frame. These rods lie parallel to the common axis of the annulus 2a and the annulus 3, the position of which is at the annulus 2a at one end of the framed part 3. There is up to the part.

The first rod 1a of the two conductive rods is shorter than the second rod 1b, and the connecting ring 3 is divided into a first portion 3a and a second portion 3b. The first rod 1a is in contact with the linkage 3 at the first portion 3a, which is close in distance from the annular portion 2a, while the second rod 1b is remote in distance from the annular portion 2a. In contact with the linkage 3 at the second part 3b.

After assembling the collector accessory as described above, the connecting ring 3 is formed with a groove in the center portion along the circumference to form two electrically separated parts.

Collectors of this type can be found in the French patent applications FR-2.710.197, FR-2.710.199 and FR-2.710.200. However, there are many problems with this type of collector.

In practice, when fabricating this type of collector, it is important to correctly position the first rod 1a and the second rod 1b when forming the outer insulating layer. This is to prevent the first rod 1a and the second rod 1b, which should be correctly insulated, from being insulated from inside or outside the collector. Otherwise, there is a risk of being grounded with the shaft of the alternator, and there is also a risk that a short will occur between the first portion 3a and the second portion 3b of the alternator linkage 3.

The portion indicated by the arrow in FIG. 1 is a portion in which a short or ground phenomenon may occur well.

The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to provide a method of manufacturing the accessories of the alternator collector or AC power generation starter, in particular, the method of manufacturing the accessories of the collector or AC power generation starter of the automotive alternator It is.

The collector accessory according to the invention is manufactured as follows.

The outer frame of insulating material is formed on two conductors placed in parallel and connected by a connecting ring. There are two annular parts in this linkage, the first annular part being in contact with one conductor and the second annular part being in contact with the other conductor.

In addition, according to the method of the present invention, a protector made of an insulating material is formed on at least one part of one or two conductors.

Several variants of the invention can be considered:

The above-mentioned shield may be made by forming a pre-frame made of insulating material, which should be done before the forming of the contour on the two conductors.

The shield of insulating material may also consist of a part enclosing the conductor, in which case it must also be done in advance of the forming of the contours on the two conductors.

The protective material of the insulating material may also consist of an epoxy resin film surrounding the conductor, in which case it should also be done in a step earlier than forming the outline of the two conductors.

The conductor may also be a metal wire conductor, in which case the protective layer of insulating material may consist of a sheath surrounding the metal wire.

The invention also relates to a collector of an alternator or an accessory of an alternating current starter, in particular an accessory of a collector or an alternating current starter for an automotive alternator. This accessory contains two conductors placed in parallel, an outer frame of insulating material, and a connecting ring that is divided into two annular parts. The first annular portion of the connecting ring is in contact with one conductor and the second annular portion is in contact with the other conductor. A protective body made of an insulating material is provided between the at least one conductor and the outer frame.

Hereinafter, with reference to the accompanying drawings, the features and advantages of the present invention will be described. The matters described below are non-limiting as examples.

2 is a cross-sectional view showing an embodiment according to the present invention.

As shown in FIG. 2, the method is preceded by a dielectric insulating material prior to forming the outline 2 in the first and second bars 1a and 1b, which may cause short and ground problems. -Form a frame.

The method can be made as follows.

The conductive rods 1a and 1b are cut from the roller for copper processing using a press. The press used at this time has a capacity capable of processing 3000 pieces per hour, and the presses are cut in the shape of the rods 1a and 1b.

Then, a pre-frame is formed in the portion to be insulated from the rod.

The part to be insulated is, for example, a few millimeters in length, so that a coating layer can be applied to about 50% of the rod length.

The material used for forming the pre-frame may be a thermoplastic material, for example polyamide or polypropylene.

Of course, the portion where the first rod 1a and the second rod 1b are in contact with the first portion 3a and the second portion 3b of the connecting ring 3, or the rods are connected to an electric line or an electric cable. The part to be connected is not preformed with the insulating material.

After this pre-formation, the cutting of the rod is completed, bent with a tool and held in the correct shape.

After the pre-frame is formed and equipped in a suitable form, the frame is formed using the form 2 forming material on the rods. At this time, the shape forming material used is a thermosetting material.

The connecting ring 3 is connected to the accessory thus made.                     

The method described above includes several advantages.

First, it is possible to simplify the method necessary to maintain the position of the rod when forming the frame as a material constituting the portion of the outline frame (2) intersecting the rotor shaft of the alternator.

Second, in view of the construction concept of this method, it is possible to reduce the failure rate.

This may be especially important if the collector accessory manufacturer does not know the possibility of a short phenomenon between the first part 3a and the second part 3b of the linkage. In fact, in general, the collector accessory is provided with a circular grooveless linkage 3. The separation of the first portion 3a and the second portion 3b is possible only after assembly.

The pre-frame 4 also gives the rod a series of strengths, which simplifies the connecting rod. If the connecting rods are not simplified, the shape of the rods, the ribs of the rods and the material of the rods should be used, which can have a natural strength that does not move when forming the outline.

The pre-frame has the advantage of protecting all sides of the rod.

In addition, according to the method proposed in the present invention, it is possible to solve the problem of the quality of the corresponding accessory, and it will be understood that the method can be performed while using an industrial tool used in the related art.

In addition to the methods described above, the present invention may be implemented in various other ways.                     

In particular, the insulating material 4 is such that, instead of using a pre-frame made of insulating material, it is possible to replace the insulating material by using a flexible locking device that can cover the form of the component, for example, a conductor. .

Installation work of such parts may be done manually or in an automated manner.

This part may be in the form of an annulus or in the form of a sheath.

As another variant, the insulating material 4 may be replaced with an epoxy resin film. In this case, the part to be insulated of the rod is surrounded by this film.

As another variant, the rod may be replaced by another type of connector, in particular a metal wire, ie a copper wire with a sheath on the part to be insulated.

These variants also have several advantages previously described.

However, the rod-formed rod type is most preferred.

As already mentioned, the first part 3a and the second part 3b of the connecting ring must form an aggregate track for the brush connected to the voltage regulator in which the alternator is contained, and the ends of the rods 1a and 1b. They must be connected to the end of the excitation bobbin that the rotor of the alternator is contained through a wired connection in the annular portion (2a).

This alternator is a bidirectional rotary electric machine, in which an electric motor can be used. Specifically, it can be used as a starter used to start a heat engine (motor) of an automobile, and such a device is called an alternating current starter.

 According to the present invention configured as described above when the outer frame of the alternator rotor shaft forming work, it becomes easy to maintain the position of the rod, can reduce the potential of defective, the protector on the rod The effect of giving a series of strengths can be obtained.

Therefore, through the method proposed by the present invention can improve the quality of the accessories, there is also an advantage that can be used in the conventional industrial tools.
