Abstract
The utility model provides a commutator. The commutator comprises an insulating substrate and a plurality of commutator segments which are distributed on an outer circumferential surface of the insulating substrate and are bonded with the insulating substrate. Adjacent commutator segments are mutually insulated through insulating grooves; one end of each commutator segment is provided with a wire hanging hook; one end of the insulating substrate, which is adjacent to the wire hanging hooks, protrudes outwards along the axial direction of the insulating substrate to form an installation portion; and the outer diameter of the installation portion is less than the outer diameter of a binding portion of the insulating substrate and the commutator segments. According to the commutator provided by the utility model, one end of the insulating substrate, which is adjacent to the wire hanging hooks, protrudes outwards along the axial direction of the insulating substrate to form the installation portion which can facilitate the installation of a motor rotor; and at the same time, the outer diameter of the installation portion is less than the outer diameter of the binding portion of the insulating substrate and the commutator segments, which reserves enough space for wire-hanging of the wire hanging hooks, thereby facilitating wire-hanging and indirectly facilitating the installation of the commutator.

Background technology
Commutator is one of critical piece of brush motor, be widely used in the electric motor, it comprises insulating body and is distributed in the periphery of insulating body and some commutators of being combined with described insulating body, by the insulation tank insulation, an end of each described commutator segment arranges a wire-hanging hook that is used for hanging wire between the adjacent described commutator.When mounted, want so that described commutator is coaxial and reserve enough hanging wire gaps with described rotor, but, in the prior art, because the design of commutator is unreasonable, especially the structural design of insulating body is unreasonable causes existing commutator or is difficult to hanging wire, and perhaps rotor is installed inconvenience.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of commutator of being convenient to install.
For this reason, the utility model provides a kind of commutator, comprise insulating body and be distributed in the outer circumference surface of described insulating body and some commutator segments of being combined with described insulating body, pass through the insulation tank mutually insulated between the adjacent described commutator segment, one end of each described commutator segment arranges a wire-hanging hook, one end of the close described wire-hanging hook of described insulating body axially outwards outstandingly forms an installation portion along it, and the external diameter of described installation portion is less than described insulating body and external diameter described commutator segment bound fraction.
Described installation portion is axially outwards outstanding along described insulating body.
The radial thickness of described installation portion is 2-8mm.
The axial height of described installation portion is for being 3-15mm.
Described wire-hanging hook has a standing part and a hanging wire part, and described standing part is perpendicular to described commutator segment.
On described commutator segment and the inwall that described insulating body combines at least one hook sheet is set.
The planar shaped at described hook sheet and described commutator segment place acutangulates α, and described sharp angle α is 45 °
The commutator that the utility model provides has the following advantages:
The commutator that the utility model provides, comprise insulating body and be distributed in the outer circumference surface of described insulating body and some commutator segments of being combined with described insulating body, pass through the insulation tank mutually insulated between the adjacent described commutator segment, one end of each described commutator segment arranges a wire-hanging hook, one end of the close described wire-hanging hook of described insulating body axially outwards outstandingly forms an installation portion along it, and the external diameter of described installation portion is less than described insulating body and external diameter described commutator segment bound fraction.The commutator that the utility model provides, described insulating body are axially outwards given prominence to along it near an end of described wire-hanging hook and are formed an installation portion, and described installation portion is convenient to mounting rotor of electric motor; Simultaneously, the external diameter of described installation portion is less than described insulating body and external diameter described commutator segment bound fraction, and this has reserved enough spaces for the hanging wire of wire-hanging hook, has made things convenient for hanging wire, thereby has indirectly made things convenient for the installation of described commutator.
