Description

Voltage regulator of automotive alternator {Regulator of alternator for vehicle}

The present invention relates to a voltage regulator of an automotive alternator, and more particularly, to eliminate the hassle of changing to a connector type and a stud type according to the specification of a vehicle so that one voltage regulator can cope with specification changes.

The automotive alternator is one of the engine electronics, which is connected to the engine and the belt to charge the consumed battery power and to supply the current required for operation with other electronics.

The automotive alternator is largely composed of a stator assembly press-fitted between a driver and a slip ring end frame and a rotor assembly supported by a rotor shaft inside thereof.

Outside the slip ring of the rotor assembly is a configuration that is provided with a voltage regulator and the like to rectify the generated alternating current into a direct current to the battery to charge and maintain the generated voltage in a constant state.

Such a conventional voltage regulator is as shown in Figures 2 to 5;

The voltage regulator 1 has a housing 2 incorporating various elements necessary for voltage regulation in order to maintain a uniform amount of difference electricity generated by high and low rotations of the engine and a connection necessary for electric current transfer. ) Or stud (4).

The connector 3 and the stud 4 are separated into a voltage regulator 1 having only the connector 3 or a voltage regulator 1 having only the stud 4 according to the specification of the vehicle, and the connector 3 as described above. Only the appearance of the housing 2 changes depending on the nya stud 4.

That is, the voltage regulator 1 having the connector 3 has a shape in which the brush holder 5 is integrally formed, and the pressure regulator 1 having the stud 4 is provided in a shape in which the brush holder 5 is removed. .

The conventional voltage regulator as described above should be equipped with a voltage regulator in accordance with the specification changes in the state always equipped with two kinds of voltage regulators according to the specification of the vehicle, the unnecessary production cost is burdened and the production cost due to the increase of the logistics cost accordingly There are several problems, such as the increase of, and the case of mounting incorrectly with a different type of voltage regulator during the installation process.

Accordingly, the present invention is to solve the problems described above, by having a connector and a stud together in the voltage regulator to cope with a single voltage regulator even if the specification of the vehicle to reduce the production and logistics costs and incorrect mounting It aims to contribute to the improvement of productivity and assemblability by excluding concerns.

Hereinafter, with reference to the accompanying drawings will be described the configuration, operation and effects of the present invention for achieving the above object.

1 is a cross-sectional configuration diagram of an automotive alternator for explaining the present invention, FIG. 6 is a front view of a connector and a stud voltage regulator to which the technique of the present invention is applied, and FIG. 7 is a connector and stud combined to which the technique of the present invention is applied. A side view of the voltage regulator will be described together.

Automotive alternator 50 is shown in Figure 1;

A stator assembly 15 composed of a stator core 13 and a stator coil 14 is press-fitted between the driver end and the slip ring end frames 11 and 12.

Inside the stator assembly 15, a rotor shaft 17 supported by a bearing 16 press-fitted to the driver end frame and the slip ring end frames 11 and 12 is provided in the transverse direction.

The spool bobbin 20 wound around the rotor coil 18 is press-fitted in the middle of the rotor shaft 17, and the rotor cores 21 and 22 having a plurality of rotor poles are coupled to the outside of the spool bobbin 20. To accommodate the spool bobbin 20.

The slip ring 25 connected to the brush 23 is press-fitted to the end (rear end) of the rotor shaft 17 and the lead wire 26 of the slip ring 25 is connected to the rotor coil 18. Thus, the rotor assembly 27 is provided.

Outside the slip ring 25 of the rotor assembly 27, a voltage regulator 30 that maintains a voltage generated in the stator assembly 15 and the rotor assembly 27 in a constant form, and an alternating current in which the voltage is adjusted. It is a configuration provided with a rectifier 29 for rectifying.

In the present invention, the voltage regulator 30 is improved so that it can be applied to one voltage regulator 30 regardless of the specification of the vehicle.

Looking at the configuration of the present invention for achieving the above object through 6 to 7 as follows.

The voltage regulator 30 includes a housing 31 incorporating various elements necessary for voltage regulation and a connection 32 for electric current transfer, in order to maintain uniform amounts of difference electricity generated by high and low rotations of the engine. ) Or stud 33.

In the voltage regulator 30, the voltage regulator 30 having the connector 32 has a shape in which the brush holder 35 is integrally formed on one side of the housing 31, and the pressure regulator 30 having the stud 33 is formed. The brush holder 35 is provided in the housing 31 in a deleted shape.

In the present invention, the brush holder 35 is integrally formed on one side of the housing 31 so that the stud 33 is integrally provided to the voltage regulator 30 having the connector 32; It is characteristic.

Obviously, the position of the connector 32 and the stud 33 provided in the voltage regulator 30 is provided at the same position as that of the connector type and the stud type voltage regulator 30.

The present invention as described above;

Since the connector 31 and the stud 33 are provided together in the housing 31 of the voltage regulator 30, even if the specification of the vehicle is changed, only one voltage regulator 30 is used, thereby enabling active response.

In particular, the provision of only one type of voltage regulator 30 reduces the logistics cost for unnecessary production, storage, and movement, and the possibility of incorrect mounting because the voltage regulator 30 is not a heterogeneous item but a single item. Sex is excluded.

As described above, the present invention has a connector and a stud together in the voltage regulator, so that even if the specification of the vehicle is changed, it is possible to cope with one voltage regulator, thereby reducing the production and logistics costs and eliminating the fear of incorrect mounting, thereby improving productivity and assembly performance. It can contribute to the improvement.
