Description

Technical Field

[0001] This utility model relates to the field of automotive generator technology, specifically to an automotive generator rectifier bridge bracket. Background Technology

[0002] The rectifier bridge of an automotive alternator is a key component of the alternator system. Its main function is to convert the alternating current (AC) generated by the alternator into direct current (DC) to meet the power supply requirements of the vehicle's electrical system. The rectifier bridge typically consists of six diodes, forming a three-phase full-wave rectifier circuit. Through the unidirectional conductivity of the diodes, the polarity change of the alternating current is converted into stable direct current. The design and optimization of the rectifier bridge have a significant impact on vehicle performance and fuel economy. For example, optimizing the rectifier bridge can improve instantaneous discharge capability, enhance torque output, shorten start-up time, improve ignition efficiency, and reduce engine vibration. Furthermore, the structural design of the rectifier bridge is constantly being improved, such as by using heat sinks and ventilation holes to improve heat dissipation and extend its service life.

[0003] An automotive alternator rectifier bridge, as disclosed in publication number CN207968343U, comprises two stacked mounting plates with a snap-fit ​​space between them, diodes mounted on the two mounting plates, copper sheets, conductive contacts at the diodes, and lead wire assemblies extending to the outside of the two mounting plates via wires. It also includes a circular tube on the mounting plates and a fixing through-hole. The key feature is that the diodes are avalanche diodes, which are chip-based, circular in shape, and directly soldered onto the copper sheets. The diameter of the circular chip is larger than that of existing avalanche diodes. A heat sink is provided on the circular chip, which is fixed to the heat sink using thermally conductive double-sided adhesive. An anti-vibration pad is provided on the outer side of the mounting plates. This invention provides an automotive alternator rectifier bridge that can keep the mounting plates firmly positioned even during significant vehicle vibrations, increases output power, and reduces costs and improves efficiency during production.

[0004] The aforementioned devices are connected by bolts between the brackets during use, which is inconvenient for replacement and results in poor stability. Therefore, we propose an automotive alternator rectifier bridge bracket to solve the problems mentioned above. Utility Model Content
