Lug inserts the hole in ear of the line lid left and right sides respectively, and more than half cylinder of terminal clamp inserts in more than half circular hole of line lid.
Compared with prior art, the invention have the advantages that
(1) material saving, save part, lightweight:
Traditional metal end and brush basin are integrated, therefore eliminate brush cone material；
Owing to this integrated (afterwards) end cap have employed the preferable plastic material of rigidity, its central authorities have the cylindrical hole can be with
The axle (static) of motor is fixed together, and axle is connected with bearing inner race, and drives armature to operate by bearing outer ring,
Thus eliminate drive end bearing bracket；
Three Kong Zhu of this electric device periphery are fixed on one by screw (the most high and low tooth) and mounting bracket
Rise, three gussets of conventional motors and three nuts, three screws can be saved；
The material of the spill guide rail supporting brush is the own material of integrated end cap, thus eliminates the brush of traditional structure
Hold material (copper)；
Negative pole is directly grounded, and saves an electric capacity than traditional π shape filter circuit, and filter effect is suitable；
Brush and inductance, electric capacity, ground strip, the direct butt-joint of lead-out wire of power supply connect together, and eliminate connection sheet.
(2) manufacturing procedure is few, dimensional accuracy is higher, save space and axial distance:
Install brush basin, brush carrier, connection sheet, inductance folder, drive end bearing bracket, thus have manufacturing procedure few, accumulation
Tolerance is little, dimensional accuracy is easier to the advantage that ensures, also saves space and axial distance simultaneously, makes to be assembled into
Motor is less than general motor volume, more flat.
(3) reliability is high, the life-span is long:
The electric device of the present invention, eliminates brush basin, drive end bearing bracket, brush carrier etc., beneficially brush and motor internal
Heat radiation；Show naked on brush, between bottom surface and the end cap of brush, leave enough gaps, brush can be avoided at brush
The possibility blocked by carbon dust in holding；Brush front end contacts with diverter, and its rear end is by coming from the bullet of stage clip
Power, two groove at side surfaces of brush are embedded in the plane of spill guide rail and can relatively slide, and brush is axially contact with guide rail
Well, it can be ensured that the reliable and stable work of brush；Brush is had ready conditions suitably increases length to improve life-span and increasing further
High-power；Thus product reliability is high, service life is long.
(4) the stage clip diameter of traditional structure is the biggest, and for preventing stage clip from deviating from brush carrier, plastics brush carrier needs to increase in this way
Add thrust plate, not only add operation, and have impact on the use length of brush；Copper brush carrier in this way, brush to be increased
Hold and close the door after installing stage clip operations such as (material) bending, when this process operations the most at that time, it is possible to make brush carrier deform,
Thus also need to increase detection operation.
And the stage clip of the present invention, it is made up of big footpath standing part and path working portion two parts, participates in working portion
Stage clip be positioned at the arcuate groove under guide rail, standing part is positioned in the open slot of guide rail, prevent stage clip depart from arc
Groove, owing to stage clip contact is reliable, thus it stably forces in brush.The most with low cost, simple for structure, and work
Sequence is few, and reliability is high.
(5) left and right of gland is equipped with hole ear, uses softer plastics, is conducive to strutting lug, thus convenient
Cover on the boss of integrated end cap, be provided with a more than half circular hole in the middle of it, be for the ease of the large semicircle with end cap
Post is accurately positioned.
