For achieving the above object, the utility model provides following technical scheme: a kind of direct current micromotor, comprise stator module and rotor assembly, stator module comprises stator and support, described support is fixedly installed on stator end, and rotor assembly comprises armature spindle, rotor and commutator segment, and commutator segment is electrically connected to drive rotor to rotate with power supply, described support is provided with the positive and negative terminal being electrically connected with commutator segment
Described support comprises the main part and the buckling parts that are detachably fastened and connected, and the another side of main part relative stator is provided with two and connects groove, connects in groove and is equipped with long guideway, and the length of this long guideway is identical with the length that connects groove;
Described positive and negative terminal includes the electrical connection section, installation portion and the contact portion that are wholely set successively, and the long guide groove that the installation portion of positive and negative terminal is equipped with the positive and negative terminal of long guide groove fastens mutually with two protruding long guideways that connect in groove respectively;
Described electrical connection section is electrically connected with commutator segment, and electrical connection section is placed in the place that removably connects of main part and buckling parts.
By adopting technique scheme, by the direct manner of protruding column of the prior art and through hole, the mode that the guide rail guide groove mode of long guideway and long guide groove of changing to cooperatively interacts, because groove is for connecting groove, the length of long guideway is identical with the length that connects groove, so long guideway is also to have run through installation portion, can effectively prevent that positive and negative terminal from departing from groove; In addition, such structure can effectively prevent that positive and negative terminal is after long-term work, occurs that the situation of fracture occurs because of the elastic movement of contact portion.
The utility model is further set to: described long guide groove is dovetail groove, and described long guideway is the dovetail shaped projection coordinating with it.
By adopting technique scheme, facilitate positive and negative terminal and connect the long guideway realization fastening in groove, structure is very simple and convenient.
Brief description of the drawings
Fig. 1 is the structure explosive view of the utility model direct current micromotor embodiment;
Fig. 2 is the structure explosive view of support and positive and negative terminal.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model direct current micromotor embodiment is described further.
A kind of direct current micromotor, comprise stator 1 assembly and rotor 4 assemblies, stator 1 assembly comprises stator 1 and support 2, described support 2 is fixedly installed on stator 1 end, rotor 4 assemblies comprise armature spindle 3, rotor 4 and commutator segment 5, commutator segment 5 is electrically connected to drive rotor 4 to rotate with power supply, described support 2 is provided with the positive and negative terminal 6 being electrically connected with commutator segment 5
Described support 2 comprises the main part 21 and the main part 22 that are detachably fastened and connected, the another side of main part 21 relative stator 1 is provided with two and connects groove 23, connect in groove 23 and be equipped with long guideway 24, the length of this long guideway 24 with connect the length of groove 23 identical (it should be noted that, length direction is that A in Fig. 1 is to direction) herein;
Described positive and negative terminal 6 includes the electrical connection section 61, installation portion 62 and the contact portion 63 that are wholely set successively, and the long guide groove 25 that the installation portion 62 of positive and negative terminal 6 is equipped with the positive and negative terminal 6 of long guide groove 25 fastens mutually with two protruding long guideways 24 that connect in groove 23 respectively;
Described electrical connection section 61 is electrically connected with commutator segment 5, and electrical connection section 61 is placed in the place that removably connects of main part 21 and main part 22.
It should be noted that herein, also can be in the structure of directly perforation groove 23 being directly arranged to dovetail groove, then form long guideway 24 at installation portion 62 towards a side that connects groove 23, thereby form the fit system of guide rail guide groove, although consider that such structure can reach identical beneficial effect, but also may will cause installation portion 62 can protrude from the another side of support 2 relative stator 1, not very attractive in appearance, but also can increase the volume of whole electrical micro-machine, therefore the present embodiment is preferred, connecting the interior long guideway 24 that arranges of groove 23, just, the long guide groove 25 of dovetail dress is set on negative terminal 6.
