Modularized vehicle rectifier bridge

Abstract

The invention discloses a modularized vehicle rectifier bridge. A utility model (single-arm bridge vehicle rectifier diode) (2) (the application number is 200920041858.7) of the company is used as a mechanical core and clamped between a positive plate (3) and a negative plate (1); the positive plate (3) and the negative plate (1) are welded at both ends of the single-arm bridge vehicle rectifier diode (2) by one-step vacuum welding; and both ends of the positive plate (3) and the negative plate (1) are connected by hollow rivets (6); one hollow rivet (6) is the positive electrode output port of the rectifier bridge; the other hollow rivet (6) is the negative electrode output port of the rectifier bridge; and the hollow rivets (6) is welded and molded with the positive plate (3) and the negative plate (1) in one step. The modularized vehicle rectifier bridge has no lead connection, improves the quality and prolongs the service life of the vehicle rectifier bridge, has simplified process, high production efficiency and low manufacture cost, does not need fastening pieces for connection and prevents the fastening pieces from loosening or dropping off due to vibration to cause generator failure.

Description

technical field [0001] The invention relates to an automobile electrical appliance, in particular to a modular automobile rectifier bridge used on an automobile generator. Background technique [0002] The automobile rectifier bridge is an important part of the automobile generator. The automobile generator generates alternating current, while the electrical appliances on the automobile use direct current. The rectifier bridge realizes the conversion between AC and DC. When the automobile rectifier bridge is working, it will generate a lot of heat, and its own heat dissipation ability is very poor. The automobile rectifier bridge is installed on the rear end cover of the automobile generator, and after the generator is running, the fan blades are driven to cool the rectifier bridge. At the same time, the rear end cover attached to the generator utilizes the outer shell of the generator to dissipate heat. The current automobile rectifier bridges all have a structure in whic...

Problems solved by technology

Regardless of whether the plates are separated up and down or left and right, they are all connected by lead wires, and the lead wires are in point contact with the chip and the electrode plate. When the current is working at a high level, it is easy to fuse, which is the cause of the failure of the automobile rectifier bridge. main reason
