Description
Technical field
The present invention relates to motor component fields, and in particular to a kind of multipurpose motor brush holder.
Background technology
Motor is a critical function component of automobile, and motor includes end cap, brush holder and the rotary body installed that cooperate,
The effect of brush holder is that pressure is added on the carbon brush slidably contacted the surfaces with commutator or collector ring by spring, makes it in end cap
Electric current is steadily conducted between rotary body.For motor, brush holder and carbon brush are all very important component.No matter carbon brush
How well is characteristic, and when brush holder is improper, carbon brush cannot not only give full play to its good characteristic, but also can give the property of motor itself
Prodigious influence can be brought with the service life.Brush holder is to maintain brush box part of the carbon brush on specified position, and carbon is pushed down with appropriate pressure
Brush vibrates to prevent blocking brush.
Previous brush holder uses on the circuit that multiple carbon brush are connected in a manner of scolding tin inside brush holder, to form one
A circuit, and avoid carbon brush and vibrated during motor operation, but such mode there is a problem of it is following：
1, production technology is complicated, low production efficiency and there are motor breaking hidden danger；
2, motor electric current during commutation is unstable, is also easy to produce commutation spark, influences EMC (the battery compatibilities of motor
Property) effect；
3, the carrying electric current of motor is low, and performance is unstable.
Invention content
For the deficiency in the presence of the prior art, the purpose of the present invention is to provide a kind of multipurpose motor brush holders, with solution
Certainly in the prior art, the problem of current of commutation of motor is unstable, carrying electric current is low, performance is unstable and low production efficiency.
To achieve the above object, present invention employs the following technical solutions：A kind of multipurpose motor brush holder, including brush holder sheet
Body, the brush holder ontology include annular base, and annular base outer ledge is integrally formed with signal connector, and on annular base
Circumferentially there is multigroup spaced carbon brush mounting box for installing carbon brush, is provided with and wears in the bottom wall of the annular base
Enter the special-shaped connection component in signal connector, special-shaped connection component is by the carbon brush installed in each carbon brush mounting box by going here and there simultaneously
It is coupled the mode closed to be electrically connected；
The abnormity connection component includes the first special-shaped connection sheet being set up in parallel and the second special-shaped connection sheet, a part of group
Carbon brush mounting box connects to form the first circuit with the first special-shaped connection sheet, and another part group carbon brush mounting box and the second abnormity are even
Contact pin connects to form second servo loop, and the first circuit is arranged in parallel with second servo loop；Described first special-shaped connection sheet and the second abnormity
Connection sheet includes the major arc linkage section that is arranged in the bottom wall of annular base and the plug terminal being arranged in signal connector,
Major arc linkage section is connected by straight line linkage section with the plug terminal being correspondingly arranged, the major arc linkage section of the first special-shaped connection sheet
On the inside of the major arc linkage section of the second special-shaped connection sheet and interval is oppositely arranged, the major arc linkage section of the first special-shaped connection sheet and
It is convex that multiple " Qian " shapes to the direction projection of carbon brush mounting box are arranged at intervals on the major arc linkage section of second special-shaped connection sheet
It rises, which part carbon brush mounting box is arranged in a one-to-one correspondence respectively in the adjacent first special-shaped connection sheet and the second special-shaped connection sheet
Two fall " Qian " shape protrusion between.
Compared with the prior art, the present invention has the advantages that：
1, connection in series-parallel combinational circuit is formd by the first special-shaped connection sheet, the second special-shaped connection sheet and multigroup carbon brush, it will
After this brush holder ontology is mounted on motor, even if one of carbon brush breaks down, other carbon brush can also make
Motor continues normally to work；
2, it is welded by intermediate frequency between the special-shaped connection sheet of first in this brush holder, the second special-shaped connection sheet and each carbon brush
Mode be attached, avoid the production efficiency that brush holder is substantially increased using air pollution caused by scolding tin mode, reduce
Process complexity；
3, the connection type in the circuit in this brush holder, increases the overload current ability of motor, reduces commutation spark
Generation, and improve the consistency and EMC performances of motor performance；
4, " Qian " the shape protrusion of falling being arranged in the first special-shaped connection sheet and the second special-shaped connection sheet makes the first special-shaped connection sheet
The setting stablized with the second special-shaped connection sheet avoids the first special-shaped connection sheet and second in the process of running in annular base
