Abstract

The invention discloses a brush yoke assembly of a voltage regulator. A chip of the voltage regulator is connected with a multi-layer circuit through a peripheral circuit. The brush yoke assembly is characterized in that a brush yoke of the voltage regulator is integrated by injection molding.

Description

technical field [0001] The invention relates to the technical field of automobile generators, in particular to a voltage regulator brush holder assembly. Background technique [0002] At present, the brush holder assembly of the automotive generator voltage regulator mostly uses semiconductor devices integrated on a substrate, or is supplemented with a thick film circuit to manufacture a single-chip integrated circuit voltage or thick film integrated circuit regulator (chip). The pins connect the chip with the brush holder by welding. Such as figure 1 as shown, figure 1 It is a schematic diagram of the overall structure of the voltage regulator brush holder assembly commonly used in the prior art. The voltage regulator includes a chip 130 and a pin 131 . The chip 140 is an integrated circuit packaged in a cooling case. The chip is placed on the brush holder in parallel, and the pins 131 of the chip 140 protrude vertically from the cooling case of the voltage regulator. T...
