Abstract
The utility model relates to a brush carrier of mini watt DC motor to solve the problem of the structure of the brush carrier, which comprises a ring-shaped chassis, more than one tubular brush handle, an electric brush moving in the tubular brush handle, an equilibrant spring corresponding to the electric brush and positioned in the tubular brush handle and electric brush wire connected on one end of the electric brush, wherein the tubular brush handle ranges radically on the ring-shaped chassis and the extended end of the tubular brush handle is provided with a dipped finish. The utility model improves the structure of the tubular brush handle and the dipped finish employed by the tubular brush handle is convenient for the extension of the electric brush wire. The bottom of the tubular brush handle is connected with the ring-shaped chassis with riveted joint, which prevents displacement and increases fastness of the overall structure. The electric brush is provided with a groove on the side, which prevents phenomenon of the electric brush being jammed caused by movement of the equilibrant spring.
Description
Technical field
The utility model relates to DC motor, especially for the brush holder of small-power DC motor.
Background technology
The brush holder of common DC motor is positioned on the same axis with the motor commutator, and it comprises annular chassis, is tubulose brush carrier, brush, the weighing apparatus power spring of radial arrangement on annular chassis around commutator.The small-power DC motor brush holder of used for automobile air conditioning for example.This brush holder exists following problem usually: the one, because the brush in the tubulose brush carrier all is movably, brush one end is connected with brush wire, brush wire moves with brush and stretches, the wearing and tearing of work center brush, and brush wire is contacted with tubulose brush carrier lateral edge has increased resistance; The 2nd, brush and the easy displacement in spring contact site of weighing apparatus power cause the brush stuck phenomenon.Therefore the relevant person manages further to improve on structure.
Summary of the invention
At the defective that prior art exists, for solving the structure problem of brush holder, the utility model provides a kind of brush holder of DC motor, and it can improve brush holder overall structure precision, is convenient to brush wire and stretches, and prevents that stuck phenomenon from appearring in brush.
The utility model is to realize by following technical scheme, the brush that it comprises annular chassis, more than one tubulose brush carrier, move in the tubulose brush carrier, match with brush and be positioned at the weighing apparatus power spring of tubulose brush carrier, an end of brush is connected with brush wire, wherein the tubulose brush carrier is radial arrangement on annular chassis, brush moves in the tubulose brush carrier of weighing apparatus power spring action lower edge, and its structural feature is that the end that tubulose brush carrier brush wire extends is provided with an angle.
The described brush end that is positioned at brush wire one end is provided with a notch.
The utility model is owing to improved structural design, and the tubulose brush carrier adopts the angle shape and is provided with the electric wire block, not only is convenient to the brush wire extension but also can limits the brush wire position.The bottom surface of tubulose brush carrier adopts riveting to be connected with annular chassis, has prevented displacement, has improved integrally-built precision.Conducting strip is injection-moulded in the annular chassis the inside, makes it to become one, and has prevented because of the copper sheet distortion, has come off and cause electrical fault.Brush end is provided with notch, has avoided weighing apparatus power spring to move the brush stuck phenomenon that causes.The utility model is simple in structure, and is easy to process, reduced cost.
Description of drawings
Below with reference to drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is a tubulose brush handle assembly schematic diagram.
Among the figure, 1 is annular chassis; 2 is the tubulose brush carrier; 3 is brush; 4 is weighing apparatus power spring; 5 is brush wire; 6 is block; 7 is tubulose brush carrier angle; 8 is the brush notch; 9 is conducting strip; 10 is riveting.
Embodiment
As depicted in figs. 1 and 2, the utility model is embodiment with the small-power DC motor brush holder of used for automobile air conditioning.The brush holder of this DC motor and motor commutator are positioned on the same axis, and it comprises annular chassis 1, be radial arrangement matches at the tubulose brush carrier 2 on the annular chassis 1, the brush 3 that moves in tubulose brush carrier 2, with brush 3 and be positioned on the end of weighing apparatus power spring 4, brush 3 of tubulose brush carrier 2 and on the plane (or lower plane) brush wire 5 is housed.Annular chassis 1 is formed by plastic injection-moulded, and conducting strip 9 is injection-moulded in this annular chassis 1, not only aesthetic appearance but also be convenient to processing, and be injection molded into one and improved reliability, the material of conducting strip is a copper sheet.In the notch of annular chassis 1 and a side that is positioned at tubulose brush carrier 2 be embedded with a brush wire block 6, its material is plastics, block 6 is used for the stretching, extension of control brush line 5.This example has four tubulose brush carriers 2 to be radial arrangement on annular chassis 1, and its material is a copper sheet.Tubulose brush carrier 2 bottom surfaces and annular chassis 1 fix by riveting 10, make the brush holder overall structure firm.
As shown in Figure 3, the brush wire 5 of tubulose brush carrier 2 extends an end and is processed with an angle 7, and this angle 7 is convenient to be contained in brush wire 5 stretching, extensions of brush 3 one ends.Be positioned on brush 3 end faces of brush wire 5 one ends and be processed with notch 8, the doubling position of weighing apparatus power spring 4 length is embedded in the notch 8 of brush, touches brush 3 stuck phenomena that limit weighing apparatus power spring 4 outer moving and cause to be halved together.
Claims (4)
