The utility model content
The purpose of this utility model be to avoid weak point of the prior art and provide a kind of simple in structure, reliability is high, be not easy to occur the DC micromotor of rosin joint or dry joint during welding lead.
The purpose of this utility model realizes by following technical measures:
A kind of DC micromotor, comprise that brush assembly of electric, backstop pad, bearing, middle part have the cover plate of first groove, have the middle plate of second groove and the lead-in wire with metal end, plate is fixed on the described cover plate in described, described backstop pad and described bearing fixing are in first groove of described cover plate, described brush assembly of electric comprises support, described support inserts second groove that is fixed in described middle plate, described brush assembly of electric also comprises straight plate part and bending part, and the metal end of described lead-in wire is fixedly welded in " V " type groove that is formed by described straight plate part and described bending part.
Preferably, the bending part of above-mentioned brush assembly of electric is upwards bending.
Preferably, above-mentioned straight plate part and the formed angle of described bending part are more than or equal to 30 ° and smaller or equal to 70 °.
The utility model compared with prior art has the following advantages: because the metal end of the lead-in wire of DC micromotor of the present utility model is fixedly welded in " V " type groove that is formed by described straight plate part and described bending part, it is simple in structure; Clamp the metal end of lead-in wire by straight plate part and bending part, so not only can be easy to metal end is placed in " V " type groove, and be not easy to occur the situation of rosin joint or dry joint during the metal end of welding lead, namely be not easy to occur the bad situation that maybe can not switch on, not rotate of DC micromotor energising.Therefore, the reliability height of DC micromotor of the present utility model and can reduce the rework rate of making and then the whole efficiency that improves the DC micromotor of making is saved manufacturing cost.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of the DC micromotor of prior art;
Fig. 2 is the fractionation structural representation of the DC micromotor of prior art;
Fig. 3 is the structural representation of DC micromotor of the present utility model;
Fig. 4 is the fractionation structural representation of DC micromotor of the present utility model;
Fig. 5 is the structural representation of the brush assembly of electric of DC micromotor of the present utility model.
Embodiment
With accompanying drawing the utility model is further described with the following Examples:
A kind of DC micromotor, as Fig. 3, Fig. 4 and Fig. 5 are described, comprise brush assembly of electric 10, backstop pad 20, bearing 30, the middle part has the cover plate 40 of first groove 41, have the middle plate 50 of second groove 51 and the lead-in wire 60 with metal end 61, plate 50 is fixed on the described cover plate 40 in described, described backstop pad 20 and described bearing 30 are fixed in first groove 41 of described cover plate 40, described brush assembly of electric 10 comprises support 11, described support 11 inserts second groove 51 that is fixed in described middle plate 50, described brush assembly of electric 10 also comprises straight plate part 12 and bending part 13, and the metal end 61 of described lead-in wire 60 is fixedly welded in " V " type groove that is formed by described straight plate part 12 and described bending part 13.Particularly, the bending part 13 of brush assembly of electric 10 can be upwards bending, is convenient to like this install and welding.Certainly, the bending part 13 of brush assembly of electric 10 can be downward bending.Straight plate part 12 and bending part 13 can be one-body molded, then bending part 13 bending up or down formed.
