Abstract

The utility model discloses a printed circuit board type wiper motor brush holder assembly which comprise a first carbon brush assembly, a second carbon brush assembly, a third carbon brush assembly, a first capacitor, a second capacitor, a first inductor, a second inductor, a thermal protection switch and a printed circuit board. The printed circuit board is shaped like a circular ring and is equipped with a plurality of fixed holes. The first carbon brush assembly, the second carbon brush assembly, the third carbon brush assembly, the first capacitor, the second capacitor, the first inductor, the second inductor and the thermal protection switch are fixed on the printed circuit board and are electrically connected via wiring of the printed circuit board. The first carbon brush assembly and the second carbon brush assembly are distributed on the same line, and the included angle between the second carbon brush assembly and the third carbon brush assembly is 65 degrees. The beneficial effects are that the printed circuit board type wiper motor brush holder assembly is convenient to mount, and is compact in structure, reliable in connection and high in production efficiency.

Description

Printed circuit board rain shaving electrical machine brush mount component

Technical field

The utility model relates to a kind of rain shaving electrical machine brush mount component.

Background technology

In the prior art, big or small rain shaving electrical machine brush mount component about a Φ 50mm only has three brush boxs, three carbon brush at brush holder (bakelite plate) usually.If upper except three brush boxs, three carbon brush are arranged at brush holder (remaining bakelite plate), increase again two (or three) electric capacity, two (or three) inductance, a heat portective switch; The former is rain shaving electrical machine brush mount component structure the earliest; the latter is present rain shaving electrical machine brush mount component structure; the purpose that adds electric capacity, inductance is in order to reduce the electronic harassment of motor, and the purpose that adds heat portective switch is in order to protect motor not ablated, to improve the reliability of motor.The problem of its existence: 1, the brush mount component circuit is intricate, and it is more that the low tension wire that links to each other with three carbon brush takies the motor internal space; 2, because part is more, riveting carbon brush, low tension wire, riveting electric capacity, the operation of riveting inductance spatially interacts, and qualification rate is low; 3, production efficiency is low.

The utility model content

The utility model has proposed a kind of printed circuit board rain shaving electrical machine brush mount component in order to overcome above deficiency, utilizes fixedly components and parts of circuit board.

The technical solution of the utility model is:

A kind of printed circuit board rain shaving electrical machine brush mount component; comprise the first carbon brush component; the second carbon brush component; the 3rd carbon brush component; the first electric capacity; the second electric capacity; the first inductance; the second inductance; heat portective switch also comprises printed circuit board (PCB); this printed circuit board (PCB) is annular; which is provided with some fixing holes; the first carbon brush component; the second carbon brush component; the 3rd carbon brush component; the first electric capacity; the second electric capacity; the first inductance; the second inductance; heat portective switch is fixed on the printed circuit board (PCB); and the wiring of passing through printed circuit board (PCB) is electrically connected; the first carbon brush component; the second carbon brush component is 180 degree and arranges, and the angle of the second carbon brush component and the 3rd carbon brush component is 65 degree.

The utlity model has easy for installation, compact conformation, connection is reliable, production efficiency is high beneficial effect.
