Description

Terminal composition for rectifier of automobile alternator

The present invention relates to a terminal configuration for a rectifier of an automotive alternator, and more particularly, to improve the manufacturing process by configuring a terminal using a copper wire.

Automotive alternator is one of the engine electronics that is connected to the engine and the belt to charge the battery power consumed and to supply the current required to operate the other electronics.

The automotive alternator is composed of a stator assembly that is press-fitted between the front and rear housings and a rotor assembly supported by the rotor shaft in its interior.

The rectifier located outside the slip ring of the dual rotor assembly converts the alternating current generated from the rotor and the stator assembly into direct current to rectify the generated current and apply it to a storage battery (battery) to be charged.

Such a rectifier is composed of a terminal molded on the diode and the rectifier and connected to the lead wire of the diode so that when the battery is charged in the rectified state, the current of the shaft stop is prevented from flowing backward in the direction of the rectifier.

Conventionally, a terminal connected to a lead wire of a diode that rectifies the generated electric current and prevents reverse flow is blanked by pressing a copper plate and manufactured through various bending processes.

The conventional technology as described above is a complicated process for manufacturing a terminal and a lot of loss of raw materials, as well as a significant manufacturing cost, which increases the cost of the alternator itself, thereby weakening the external competitiveness. have.

Therefore, the present invention has been made in order to solve the above problems, while simplifying the manufacturing process, while contributing to cost reduction, and in particular, it is an object of the present invention to provide a terminal for easy coupling with the lead wire of the diode.

To this end, the present invention is characterized in that the terminal to achieve the above object by forming a molded copper wire.

A typical alternator 10 includes a stator assembly 15 composed of a stator core 13 and a stator coil 14 between the front and rear housings 11 and 12, as shown in FIGS. Inwardly, a rotor shaft 17 supported by a bearing 16 press-fitted into the front and rear housings 11 and 12 is provided.

The spool bobbin 20, which is wound around the rotor coil 18 and connected to the rear slip ring 19, is press-fitted in the middle of the rotor shaft 17, and a plurality of rotor pulls 21 and 22 in the axial direction outside thereof. The rotor assembly 25 is provided in such a way that the rotor cores 23 and 24 having the coupling are coupled to accommodate the spool bobbin 20.

Outside the slip ring 19 of the rotor assembly 25, a voltage regulator 26 for maintaining the voltage generated in the rotor and the stator assembly in a constant state, and a rectifier 27 for rectifying the regulated AC to DC. ), The rectifier 27 is press-fit and fixed to the diodes 28 and 29 and the triodes 30 and 31 to rectify the generated current and prevent backflow, and the diodes 28 and 29 and the triode The lead wires 32 and 33 of the 30 and 31 are connected to the terminal 34 molded on the rectifier 27.

Conventionally, such a terminal 34 is formed in a complicated shape by blanking the copper plate as shown in FIGS. 5 and 6 through several bending processes.

For this reason, the conventional technique increases the man-hour for manufacturing the terminal 34, and in particular, stress concentration is concentrated at the bending part in the process of bending a thin thin copper wire several times. The phenomenon occurs.

In addition, since the terminal is formed of a copper plate and the end portion of the terminal, which has undergone the bending process, has a complicated shape, coupling with the lead wire of the diode is reduced, thereby having the above-described problems.

The terminal 34 of the present invention in view of the above-described conventional problems is molded in the rectifier 27 as shown in FIGS. 3 and 4 to lead wires of the diodes 28 and 29 and the triodes 30 and 31. It is possible to solve the above problem by forming the terminal 34 connected to the 32, 33 by bending the copper wire.

The present invention as described above by forming the terminal 34 in the copper wire can secure the space of the area where the lead wires (32, 33) of the diodes (28, 29) and the trio diodes (30, 31) are connected to the maximum connectivity It becomes good and can improve the performance and quality of the generator 10 by preventing breakage of the terminal due to stress concentration that may occur in the molding process.

As well as. By reducing the manufacturing process or cost of the terminal 34 can reduce the overall cost of the alternator 10 can secure external competitiveness.

The present invention as described above can reduce the manufacturing cost of the terminal while reducing the cost wrinkling, as well as to improve the quality of the generator itself.
