Principle is, when coil is by after electric current, can be under the effect of permanent magnet, by attraction and repulsive force, rotate, when it forwards to magnet balance, the commutator segment originally leading on the more corresponding commutator of line of electricity is just separated with brush, and brush is connected to and meets that produce motive force and organize on the commutator segment that coil is corresponding, so ceaselessly repeat down, DC motor has just been turned over.
At present, on market, disclose the commutator segment that a kind of application number is the commutator of CN201220141414.2, it provides a kind of film flying or floating sheet phenomenon that solves commutator segment, improves the quality of commutator and the commutator segment in life-span; It comprises commutator segment body, and the cross section of commutator segment body is circular arc, and it has an inner side cambered surface and an outside cambered surface; The inner side cambered surface of described commutator segment body is provided with the fixing feet of at least one projection, and the cross section of fixing feet is in T shape.
This commutator or similarly commutator, the mode that they adopt commutator segment inner side to increase fixing feet prevents film flying or the floating sheet phenomenon of commutator segment, but by adopting, increased in this way the materials of commutator segment volume, increased to a great extent the manufacturing cost of commutator.
Utility model content
The deficiency existing for prior art, it is a kind of with low cost and can effectively prevent the commutator of film flying that the purpose of this utility model is to provide.
For achieving the above object, the utility model provides following technical scheme: a kind of commutator, comprise insulation core body and some commutator segments, the cylindrical setting of described insulation core body and axially offer axis hole along insulation core body, described commutator segment is circumferentially uniformly distributed along core body, separate setting between described some commutator segments, wherein: described commutator segment week is upwards provided with ring-type retainer plate, and described retainer plate and insulation core body are integral type setting.
By adopting technique scheme, by commutator segment being embedded in the retainer plate forming with insulation core body integrated injection molding, reach the effect that prevents that commutator segment from coming off from insulation core body, the combining ability having increased between commutator segment and insulation core body does not need to increase again the material usage of commutator segment itself simultaneously, described retainer plate and insulation core body are made by moulding compound, its general market price is about 1/3rd of the logical alloy of silver, reached the effect that not only prevents film flying but also reduce manufacturing cost.
The utility model is further set to: on described commutator segment, offer through hole, described lead to the hole site and retainer plate over against.
By adopting technique scheme, described commutator is in integrated injection molding, described through hole has increased the connection area of retainer plate and insulation core body, has improved the bonding strength between described retainer plate and insulation core body, further prevents the situation of film flying.
The utility model is further set to: one end of described commutator segment is provided with the link vertical with commutator segment, and described link direction is away from insulation core body, and described retainer plate is arranged on the bending part of described link and commutator segment.
By adopting technique scheme, the middle part of commutator segment has been avoided in described retainer plate position, for carbon brush, has reserved enough spaces with contacting of commutator segment, and while preventing described commutator work, carbon brush causes carbon brush and commutator segment loose contact because retainer plate hinders.
The utility model is further set to: the external diameter of described retainer plate is less than linkage section external diameter.
By adopting technique scheme, described connecting portion is for welding with enamelled wire, and the restriction of described retainer plate external diameter has been avoided causing connecting portion and enamelled wire failure welding because of retainer plate size.
Compared with prior art, the utility model upwards increases a retainer plate being wholely set with insulation core body is set by adopting in commutator week, from strengthening the bonding strength of commutator segment, with respect to the mode that increases commutator segment fixing feet, not only greatly reduced commutator cost of manufacture, and anti-film flying better effects if.
