Example Embodiment

[0049] Such as Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 with Picture 9 Shown: The present invention includes a conductive negative plate 5, an intermediate support insulating support 7, a conductive positive plate 2, a bus bridge support 3, a positive output screw 1, a rectifier diode 4, a tubular rivet 16, a generator rear fixed cover 9, and a generator rear The fixed cover supports the boss 12 and the plastic protective cover 10. The rectifier diode 4 converts alternating current into direct current. The conductive negative plate 5 and the conductive positive plate 2 play the role of fixing the rectifier diode, conducting and dissipating heat. The bus bridge bracket 3 is connected to the stator line to converge, and the positive output screw 1 outputs current to the outside, and the generator back cover The supporting boss 12 supports and fixes the rectifier, and the plastic protective cover 10 protects the rectifier and adjusts the air duct of the generator....

Abstract

The invention discloses a high-efficiency flat wire generator rectifier structure, which comprises a conductive negative plate, an intermediate support insulating support, a conductive positive plate, a bus bridge support, a positive output screw, a rectifier diode, a tubular rivet, a rear fixing cover of a generator, and a generator The rear fixed cover supports the boss and the plastic protective cover. It is characterized in that: the intermediate support insulating bracket replaces the insulating bushing and is installed between the conductive negative plate and the conductive positive plate. The conductive negative plate is installed under the rectifier and fixed with the rear of the generator. The cover support boss is connected and fixed, the lower edge of the plastic protective cover is flush with the upper edge of the conductive negative plate, the bus bridge bracket is installed above the conductive positive plate, and is horizontally connected and fixed with the connecting thread of the generator stator line. Its advantages are: the use of two-way air intake makes the temperature gradient on the plate uniform, ensures the reliability of spot welding, and can meet the requirements of different output directions of customers. It not only improves the generator power and product reliability, but also increases the efficiency of the generator. overall lifespan.

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...
