High-efficiency flat wire generator rectifier structure and assembling method thereof

Abstract

The invention discloses a high-efficiency flat wire generator rectifier structure which comprises a conductive negative plate, an intermediate supporting insulating bracket, a conductive positive plate, a junction bridge bracket, positive output screw rods, rectifier diodes, tubular rivets, a rear generator fixed cover, a rear generator fixed cover supporting boss and a plastic protective cover. The rectifier structure is characterized in that the intermediate supporting insulating bracket that is used for replacing an insulating bush is installed between the conductive negative plate and theconductive positive plate; the conductive negative plate is installed below a rectifier and is connected and fixed with the rear generator fixed cover supporting boss; the lower edge of the plastic protective cover is flush with the upper edge of the conductive negative plate; the junction bridge bracket is installed above the conductive positive plate and is connected and fixed with motor statorline connection threads. The rectifier structure has the following advantages: with a bidirectional air-intake mode, the temperature gradients on the positive and negative plates become uniform to guarantee spot welding reliability; different output direction requirements of clients are met; the generator power and product reliability are improved; and the service life of the high-efficiency generator is prolonged.

Description

technical field [0001] The invention relates to an automobile rectifier structure, which belongs to the field of automobile generators, in particular to a high-efficiency flat wire generator rectifier structure and an assembly method. Background technique [0002] The car alternator is the main power source of the car. Its function is to supply power to all electrical equipment (except the starter) and charge the battery at the same time when the engine is running normally (above idling speed). With the development of electronic technology and the improvement of people's requirements for comfort, the number of on-board electrical appliances is increasing; at the same time, due to the continuous tightening and improvement of environmental protection requirements, automobile generators are developing in the direction of small size (weight) and high power. Therefore, all countries are constantly introducing new technologies to increase the number of generator stator slots and i...

Problems solved by technology

When the stator coil adopts a flat wire stator, the temperature of the rear fixed cover is high due to the heat conduction of the stator, and the rectifier diode on the rectifier rectifies and generates heat, and the temperature conduction and dissipation are poor, reaching the junction temperature of the rectifier diode, resulting in the failure of the rectifier
