Detailed description of the invention
The purpose of the present invention aims to provide a kind of stator module, and the pilot protection structure design of this stator module can improve the reliability that lead-in wire is fixing on the one hand, thus preventing solder joint to be affected；Sealing property can be improved on the other hand, it is prevented that dust or steam enter motor internal.Additionally, the purpose of the present invention is also directed to a kind of include the motor of said stator assembly, include the draining pump of this motor and the assembly method of this stator module.
In order to make those skilled in the art be more fully understood that technical scheme, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Refer to Fig. 3, Fig. 4, Fig. 5 and Figure 12, Fig. 3 is the structural representation of stator module in the first embodiment of the present invention；Fig. 4 is the structural representation of stator module in the second embodiment of the present invention；Fig. 5 is the structural representation of stator module in the third embodiment of the present invention；Figure 12 is the sectional view of stator module in the 4th kind of embodiment of the present invention.
In basic technology scheme, as shown in figure 12, stator module provided by the present invention includes stator core 1, stator winding 2, stator insulation body 3 and circuit board 4；The circumferential side of stator insulation body 3 is provided with binding post portion 31 (shown in Figure 10), and circuit board 4 is connected in this binding post portion 31, and is connected to lead-in wire 5 on this circuit board 4.
As shown in Figures 3 to 5, on the basis of said structure, the outside injection moulding of binding post portion 31 and circuit board 4 is formed with encapsulated member 6, being provided externally with and the pilot protection set of encapsulated member 6 integrated injection molding formation of lead-in wire 5.
In said structure designs, pilot protection set is formed with encapsulated member 6 integrated injection molding, and adhesion is strong therebetween, is not susceptible to separate or relative motion；Being installed in the structural design on bottom end cover relative to pilot protection set in prior art, this kind of structural design can improve the reliability that pilot protection set is fixing, and then can improve the reliability that lead-in wire 5 is fixing.
In addition; pilot protection set injection moulding is in the outside of lead-in wire 5; thus pilot protection set and the adhesion gone between 5 are strong; there is very big bond strength; thus when lead-in wire 5 is pulled; this lead-in wire 5 generally will not thus departing from pilot protection set such that it is able to improves the reliability that lead-in wire 5 is fixing, and then it can be avoided that the solder joint of lead-in wire 5 is impacted.Additionally, pilot protection set injection moulding is in the outside of lead-in wire 5, thus it is absent from gap between pilot protection set and lead-in wire 5, good airproof performance, it is thus possible to improve sealing property, it is to avoid prevent dust or steam from entering motor internal.
It should be noted that in the above-described embodiments, no matter pilot protection set adopts which kind of shape or structure, as long as its injection moulding is in the outside of lead-in wire 5, and just all should within protection scope of the present invention with encapsulated member 6 integrated injection molding.
On the basis of above-mentioned basic technology scheme, it is possible to make further improvement, thus obtaining the first embodiment of the present invention.Specifically, as it is shown on figure 3, pilot protection set includes cylindrical protective portion 71, this cylindrical protective portion 71 injection moulding is in the outside of lead-in wire 5.The structural design of cylindrical sheath, its Shooting Technique is good, and injection moulding quality can be easily obtained guarantee.
