Integrated adjustor, namely rectifier bridge of automobile alternating-current generator

Abstract

The invention relates to an integrated adjustor, namely a rectifier bridge of an automobile alternating-current generator. The integrated adjustor comprises an adjustor frame, wherein a hybrid integrated circuit, adjustor heat radiating sheets, a carbon brush, a spring and a rectifier embedded sheet are arranged on the adjustor frame. The integrated adjustor is characterized in that a rectifier bridge comprising three excitation diodes, two heat radiating sheets, two sets of rectifier diode chips and B+ bolts is installed on the adjustor frame; each set of the rectifier diode chips is respectively welded on the two heat radiating sheets; a packaging hole is arranged on the adjustor frame; the first end of the rectifier embedded sheet is a wire-connecting end of three phase positions of an alternating-current generator stator coil respectively; the second end of the rectifier embedded sheet is respectively connected with anodes of the excitation diodes; the third end of the rectifier embedded sheet is led out through the packaging hole; two ends of the heat radiating sheets are respectively sleeved on a metal sleeve and the B+ bolts; and the rectifier diode chips are packaged in the packaging hole and electrically connected with the third end of the rectifier embedded sheet respectively. The integrated adjustor has the advantages of simple structure, small volume, low production investment, low manufacture cost, convenience for installation and capability of saving the internal space of the generator.

Description

technical field [0001] The invention relates to an automobile alternator integrated regulator-rectifier bridge. Background technique [0002] At present, the regulator and rectifier bridge used in automotive alternators are split, and are installed inside the generator as two independent components. The problems of this structure are: 1. Since the rectifier diodes in the rectifier bridge are packaged, the cost of the package shell accounts for a relatively high proportion of the total cost of the rectifier bridge, and the rectifier bridge after separate packaging is relatively large in size, so the rectifier bridge The cost of the bridge is high, and the rectifier bridge and the regulator occupy a large space in the generator; 2. Since the regulator and the rectifier bridge are installed inside the generator as two independent components, it is not only time-consuming and laborious to install, but also needs to be established during production. There are at least two indepe...
