Abstract
The utility model discloses a direct current motor carbon brush frame, including carbon brush frame body, carbon brush frame body be the cylindrical casing of upper end open -ended, and bottom that the carbon brush put up the body is equipped with the shaft hole, the outside in shaft hole is equipped with the interior girth sheets of circular shape, and interior girth sheets and carbon brush frame body inboard bottom fixed connection, this internally is equipped with carbon brush frame two and uses shaft holes for central relative placement's carbon brush mount pad, and the carbon brush mount pad one end of being close to the shaft hole is equipped with the carbon brush and portals, the utility model provides a direct current motor carbon brush frame, its magnetic field and interior girth sheets that produces through the inductance, can be effectual this is internal at the carbon brush frame with the carbon dust restriction, prevent the carbon dust and reveal and lead to the fact electronics original paper and motor shell to switch on the circumstances that forms withstand voltage puncture to the effectual safety of having guaranteed equipment or domestic appliance.
Description
Technical field
The utility model relates to direct current machine equipment and household appliance technical field, specifically a kind of DC electric machine carbon brush holder.
Background technology
The effect of DC electric machine carbon brush holder 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.
In the process that motor runs, due to break-in, carbon brush, often to the carbon dust that leaks outside, causes the miscellaneous part of motor to be subject to the interference of carbon dust, there will be carbon dust and overstock, cause the phenomenon of electronic component and cabinet parts conducting, and cause certain potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of DC electric machine carbon brush holder, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of DC electric machine carbon brush holder, comprise carbon brush holder body, described carbon brush holder body is the cylindrical housings of upper end open, the bottom of carbon brush holder body is provided with axis hole, the outside of described axis hole is provided with circular interior girth sheets, and interior girth sheets is fixedly connected with carbon brush holder body inside bottom, in described carbon brush holder body, be provided with two carbon brush mount pads staggered relatively centered by axis hole, and carbon brush mount pad is provided with carbon brush near one end of axis hole portals; The outside of described interior girth sheets is provided with two inductance staggered relatively centered by axis hole, and the side of inductance is provided with fixed head, by fixed head, inductance and carbon brush mount pad is interfixed; Inductance is welded by solder or hot melt riveting electric capacity.
As further program of the utility model: it is square opening that described carbon brush goes out pore structure.
As the utility model further scheme: described carbon brush holder body adopts fire-retardant material to make.
Compared with prior art, the beneficial effects of the utility model are: the DC electric machine carbon brush holder that the utility model proposes, its magnetic field produced by inductance and interior girth sheets, can effectively carbon dust be limited in carbon brush holder body, prevent the situation that carbon dust is revealed, thus effectively ensure that the safety of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of DC electric machine carbon brush holder of the utility model.
In figure: in 1-carbon brush holder body, 2-axis hole, 3-carbon brush mount pad, 4-fixed head, 5-inductance, 6-solder, 7-, girth sheets, 8-electric capacity, 9-carbon brush portal.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of DC electric machine carbon brush holder, comprise carbon brush holder body 1, described carbon brush holder body 1 is the cylindrical housings of upper end open, the bottom of carbon brush holder body 1 is provided with axis hole 2, the outside of described axis hole 2 is provided with circular interior girth sheets 7, and interior girth sheets 7 is fixedly connected with carbon brush holder body 1 inside bottom, be provided with two carbon brush mount pads 9 staggered relatively centered by axis hole 2 in described carbon brush holder body 1, and carbon brush mount pad 9 is provided with carbon brush near one end of axis hole 2 portals 9; The outside of described interior girth sheets 7 is provided with two inductance 5 staggered relatively centered by axis hole 2, and the side of inductance 5 is provided with fixed head 4, by fixed head 4, inductance 5 and carbon brush mount pad 9 is interfixed; Inductance 5 connects electric capacity 8 by solder 6.
Described carbon brush 9 structures of portalling are square opening.
Described carbon brush holder body 1 adopts fire-retardant material to make.
Operation principle of the present utility model is: install carbon brush by the carbon brush mount pad 9 in carbon brush holder body 1, utilize two inductance 5 generation magnetic field around carbon brush simultaneously, the carbon dust produced is made to be adsorbed on interior girth sheets 7, simultaneously under the barrier effect of interior girth sheets 7, also there will not be the situation that carbon dust is revealed.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
