Description
Technical field
This utility model relates to auto-parts field, particularly to the communtator cover of a kind of standard electromotor.
Background technology
Alternating current is become DC current by the commutator in motor, produces unidirectional moment, and drive motor rotates, and is the base component of direct current generator.And communtator cover, namely brush holder, the device as fixing carbon brush position is arranged on motor internal, allows carbon brush contact energising with commutator of motor rotor, is the requisite components and parts of all direct current generators.
Existing standard motor is all ensure that motor can reach the EMC grade of main engine plants by one piece of filter circuit plate of welding, but the present main engine plants such as modern times etc. are very strict to the authentication requesting of soldering tin material and welding product.
Utility model content
Goal of the invention: in order to meet client's material requirements to product, reduces welding process, increases the reliability of product, promotes client's satisfaction to noise simultaneously, and this utility model provides the communtator cover of a kind of standard electromotor.
Technical scheme: the communtator cover of a kind of standard electromotor, including plastic casing, metal connecting sheet, circuit board and carbon brush, the middle part of described plastic casing is region, a circular location, the symmetric position positioning region in circle is provided with two carbon brush, housing near the circular overseas circumference of positioning area is provided with the draw-in groove for inserting circuit board, housing between draw-in groove and region, circular location is welded with two metal connecting sheets, said two metal connecting sheet all includes power supply positive/negative connecting portion and circuit board fixed part, one of them metal connecting sheet also includes carbon brush shunt welding connecting portion, another one metal connecting sheet also includes critesistor weld part；Described circuit board fixed part is domes, and the peristome of domes inserts in housing, and circuit board inserts between arch area and housing, can realize fixing by the elastic force of metal connecting sheet.
One of them metal connecting sheet welds a hook in the lower end penetrating housing, it is achieved that grounding function, can also embrace circuit board simultaneously, reaches to strengthen fixing effect.
Described plastic casing is provided with two plastic columns in the side relative with metal connecting sheet, it is cased with a spring respectively, one end of described spring and the exposed side contacts outside housing of carbon brush, gathering sill is had bottom carbon brush, the housing corresponding with carbon brush is provided with projection, gathering sill and projection are bonded to each other, make carbon brush can only move toward diverter direction, completely can not double swerve, improve carbon brush due to the problem that spring force is unequal and diverter is not exclusively fitted, the noise produced when reducing electric machine rotation simultaneously.
Described circuit board is welded with electric capacity, is used for realizing filter action, it is ensured that the EMC grade of whole motor meets the requirements of the customers.
Region, described circular location is being provided with multiple connection pawl vertically with the port of circuit board identical faces, is provided with reinforcement connecting, fixes by connecting pawl and reinforcement and stator, can prevent the deviation of motor commutator lid and stator relative position between pawl.
It is provided with elastic washer between described plastic casing and motor stator, is used for preventing water inlet in motor, it is ensured that the classification of waterproof of motor.
Beneficial effect: this utility model adopts as above technical scheme, has the advantage that
1, have employed the fixing small size filter circuit plate of the mode of reed pressure, decrease welding process, simplify installation process.
2, use spring to replace reed, and carbon brush is fixed in housing, it is to avoid shake the noise of generation up and down due to reed, whole spring structure is not easy to swing up and down, reduce motor and produce the probability of particular noise.
