Abstract
The utility model relates to DC motor technology field, particularly relate to a kind of brush direct current motor brush holder, comprise end cap, be fixed on the conductive copper plate of end cap, carbon brush and motor down-lead, carbon brush and motor down-lead are connected by conductive copper plate and form integrative-structure by injection moulding.Brush direct current motor brush holder of the present utility model, now adopt part combination, pass through injection molding technology, by conductive copper plate, carbon brush, lead-in wire are connected and be injected into an entirety, lead-in wire is in injection moulding process, and fairlead also reaches complete impermeable effect, and the globality of assembly is stronger, production and assembly simple and convenient, and greatly raise the efficiency, accurate dimensional fits adds rational injection moulding, makes motor reach the effect of waterproof.
Description
Technical field
The utility model relates to DC motor technology field, particularly relates to a kind of brush direct current motor brush holder.
Background technology
The effect of motor brush rocker to be added in by pressure on the carbon brush that contacts with commutator or collector ring surface sliding by spring, makes its stably conduction current between fixed body and rotary body.Concerning motor, brush holder and carbon brush are all very important parts.No matter how well, when brush holder is improper, carbon brush not only can not give full play to its good characteristic to the characteristic of carbon brush, and bring very large impact can to the performance of motor itself and life-span.
The structure of brush holder keeps the brush box part of carbon brush on assigned position, pushes down carbon brush in case the pressures partially of blocking brush vibration with suitable pressure, the frame part connecting brush box and pressures partially and the standing part composition be fixed to by brush holder on motor.Brush mount component is generally made up of carbon brush, brush-box, wire, brush holder, assemble method more complicated, comprise winding displacement, go between through coil (go between and cross between coil and have gap, cannot meet for waterproof requirement higher strip part), welding carbon brush, riveting brush holder etc.Complex structure, assembling inconvenience, globality is poor.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the technical problem that in prior art, DC motor brush rack globality is poor, waterproof effect is weak, and the utility model provides a kind of brush direct current motor brush holder.
The utility model solves the technical scheme that its technical problem adopts: a kind of brush direct current motor brush holder, comprise end cap, be fixed on the conductive copper plate of end cap, carbon brush and motor down-lead, described carbon brush and motor down-lead are connected by conductive copper plate and form integrative-structure by injection moulding.
Further, particularly, described conductive copper plate is two, conductive copper plate is divided into arc section and straightway, described arc section is positioned at cover internal, and circular arc opening is towards the center of end cap, and described straightway stretches out end cap outside and forms integrative-structure with motor down-lead by injection moulding.
Further, particularly, the junction of described straightway and motor down-lead is also set with protection objective cover, and protection objective cover is positioned at end cap outside.
In order to weight reduction, reduce environmental pollution, improve corrosion-resistant rustless property, as preferably, described end cap is nylon end cap.
The beneficial effects of the utility model are, brush direct current motor brush holder of the present utility model, now adopt part combination, by injection molding technology, by conductive copper plate, carbon brush, lead-in wire connected and be injected into an entirety, going between in injection moulding process, fairlead also reaches complete impermeable effect, the globality of assembly is comparatively strong, production and assembly simple and convenient, and greatly raises the efficiency, accurate dimensional fits adds rational injection moulding, makes motor reach the effect of waterproof.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, end cap, 2, conductive copper plate, 21, arc section, 22, straightway, 3, motor down-lead, 4, protection objective cover.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, it is embodiment of the present utility model, a kind of brush direct current motor brush holder, comprise end cap 1, be fixed on the conductive copper plate 2 on end cap 1, carbon brush and motor down-lead 3, carbon brush and motor down-lead 3 are connected by conductive copper plate 2 and form integrative-structure by injection moulding, conductive copper plate 2 is two, conductive copper plate 2 is divided into arc section 21 and straightway 22, it is inner that arc section 21 is positioned at end cap 1, circular arc opening is towards the center of end cap 1, straightway 22 stretches out end cap 1 outside and forms integrative-structure with motor down-lead 3 by injection moulding, straightway 22 is also set with protection objective with the junction of motor down-lead 3 and overlaps 4, it is outside that protection objective cover 4 is positioned at end 1, end cap 1 is nylon end cap.
Brush direct current motor brush holder of the present utility model, now adopt part combination, pass through injection molding technology, by conductive copper plate, carbon brush, lead-in wire are connected and be injected into an entirety, lead-in wire is in injection moulding process, and fairlead also reaches complete impermeable effect, and the globality of assembly is stronger, production and assembly simple and convenient, and greatly raise the efficiency, accurate dimensional fits adds rational injection moulding, makes motor reach the effect of waterproof.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
