Description

Voltage regulator for automotive alternator.

The present invention relates to a voltage regulator for an automotive alternator, and more particularly, by separately configuring a voltage regulator (regulator) for maintaining a constant voltage generated by the alternator into a housing part and a connector part, as well as actively responding to specification changes. To achieve cost and productivity gains.

In general, the automotive alternator is connected to the engine and the belt to charge the battery power consumed as one of the electrical equipment, and serves to supply the current required for the operation of the other electrical equipment.

In the automotive alternator 1, a stator assembly 14 including a stator core 12 and a stator coil 13 is press-fitted between casings 10 and 11, as shown in FIG. 1, and a casing ( The rotor shaft 16, which is supported by the bearing 15 press-fitted in 10, 11 and has a pulley p for power transmission, is provided.

In the middle of the rotor shaft 16, the spool bobbin 19, which is wound around the rotor coil 17 and connected to the rear slip ring 18, is press-fitted, and a plurality of rotor poles 20, 21 in the axial direction outside thereof. Rotor assembly 24 is provided in a configuration to accommodate the rotor core (22, 23) having a spool bobbin (19).

Outside the slip ring 18 of the rotor assembly 24, a voltage regulator 25 for maintaining the voltage generated by the rotor and the stator assembly 14 in a constant state and a stop value 26 for converting AC into direct current are fixed. do.

As described above, the alternator 1 which generates a current required for the automobile is fastened to the output shaft of the engine and the belt so that the rotor shaft 16 rotates in proportion to the rotational speed of the engine.

This represents a difference in the amount of electricity generated at low and high rotations, and the voltage regulator 26 performs an operation of keeping it uniform.

As described above, the voltage regulator 25 for maintaining a constant voltage is integrally formed with a thin housing 27 formed by interpolating various elements necessary for voltage adjustment and a connector 28 necessary for transferring current. .

The voltage regulator 25 is mounted on one side of the cylindrical casing (10, 11) in conjunction with the rectifier 26 to form a bent portion (w) corresponding thereto to double the space utilization.

The voltage regulator 25 as described above changes its specification according to the capacity of the alternator 1 and the specifications of the casing (10, 11), the standard of the housing 27 is changed by the interpolation of various elements, etc. Although the width of is extremely insignificant, the connector 28 carrying current carries many changes.

When the connector 28 of the voltage regulator 25 changes according to the request of the user or the user as described above, it is integrally formed with the housing 27 so that partial deformation is impossible, and thus the design and manufacture of the entire voltage regulator is necessary. .

This caused a huge expenditure of development time and cost, as well as a problem of having to manufacture a separate mold mold in the manufacturing stage.

Therefore, in the present invention, to solve the various problems described above, the housing and the connector necessary for the electric current transfer, which are created for the voltage regulator, are separated and configured to allow partial changes when changing the shape of the connector according to the specification change. Save time and money, and increase productivity.

It will be described together as.

One of the automotive electronics includes an alternator which is connected by an engine and a belt and supplies an electric current necessary for charging a consumed battery and operating other electronics.

In the alternator, a stator assembly composed of a stator core wound on a stator coil is pressed into a cylindrical casing, and is supported by a bearing inwardly thereof, and a rotor shaft having a pulley for power transmission is mounted at the front end thereof.

The rotor shaft is provided with a rotor assembly in which a spool bobbin wound by a rotor coil and connected to a rear slip ring is press-fitted, and a rotor core having a plurality of rotor poles is coupled to the outside thereof to accommodate the spool bobbin.

Outside the slip ring of the rotor assembly, a voltage regulator for maintaining a current generated by the generator in a constant state and a stop for switching AC to DC are fixed.

The voltage regulator 3 provided on one side of the alternator interpolates various elements necessary for voltage adjustment as shown in FIGS. 3 and 4, and is coupled to the housing 30 of the rectangular shape and one side of the housing 30. The connector 31 is comprised.

The housing 30 has a connector lead frame (35) fixing hole (32) at a fastening portion with the connector (31), and bolt holes (33) are formed at both ends of the housing to fix the case.

The corresponding connector 31 has a terminal 34 necessary for transferring electric current on one side thereof, and a lead frame 35 that is inserted into the fixing hole 32 of the housing 30 to perform an energizing role. do.

In addition, both ends of the connector 31 are fastened to the voltage regulator housing 30, and a bolt hole 33 'for fixing to the case is formed.

The voltage regulator 3 separated as described above has a lead hole 35 formed at one side of the connector 31 as shown in FIG. 5 when assembled in a production line. 32).

As described above, the lead frame 35 inserted into each of the fixing holes 32 forms a temporary assembly state with the fixing holes 35 through bending, and thus, the separation of the connector 31 and the fastening portion of the connector 31 are based on energization. All metals have a fixed structure by soldering to prevent the natural oxidative phenomenon that occurs during long-term exposure to air and during operation.

And the solder covered on the fastening part is separated from the fastening part (c) due to the constant vibration and other external factors caused by the driving of the car. To prevent this, the soldering part is coated once again by applying resin such as epoxy. Protect.

As described above, the voltage regulator 3 in which the housing 30 and the connector 31 are coupled is secured to the case by using bolt holes 33 and 33 'formed at both ends of the housing 30 and the connector 31. To complete the assembly.

In the AC generator to which the voltage regulator 3 formed as described above is applied, when the engine is started, the rotor shaft, which is powered by the engine, rotates, and at the same time, the battery power is supplied to the rotor coil through a brush connected to the slip ring. Transfers form magnetic lines in the rotor core outside the rotor coil.

At this time, when the rotor shaft rotates, three-phase alternating current is induced on the stator coil and applied to the diode of the rectifier. Supply current to other electronics.

In addition, when the voltage exceeds the prescribed value in the power generation process, the voltage regulator is operated to maintain a constant voltage state at all times, the operation of the diode to prevent the current flow back from the battery to the generator due to the engine stopped.

As described above, the voltage regulator for the alternator may be configured to separate the housing and the connector so as to quickly cope with a life time that is gradually shortened in response to changes in various specifications.

The voltage regulator for an automotive alternator according to the present invention configured as described above is a useful invention that reduces the development cost and time of a new product by rapidly responding to specification changes, improves economic efficiency, and increases productivity and contributes to cost reduction.
