The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings the grounding wire component mounting structure 10 of motor according to embodiments of the present invention is described.
As depicted in figs. 1 and 2, the grounding wire component mounting structure 10 of motor according to embodiments of the present invention includes casing
100th, support plate 200 and grounding wire component 300.
Support plate 200 is located in the outside wall surface of casing 100, and support plate 200 is provided with screw mounting hole.On grounding wire component 300
Provided with through hole, grounding wire component 300 is arranged on by the screw 400 through the through hole and cooperation in the screw mounting hole
On support plate 200.Wherein, the screw mounting hole can be screwed hole, or tapping screw bottom outlet, screw 400 can be used
Bolt replaces.
The grounding wire component mounting structure 10 of motor according to embodiments of the present invention, is set in the outside wall surface of casing 100
Support plate 200, grounding wire component 300 can be arranged on support plate 200 by screw 400, so can be by increasing support plate 200
Thickness to increase the length of fit of screw 400 and the screw mounting hole, make the length of fit of screw 400 not by casing 100
The limitation of thickness, it is possible thereby to avoid the occurrence of sliding dental phenomenon, greatly improve the reliability after grounding wire component 300 is installed.In addition,
Screw 400 is arranged on support plate 200 and outside casing 100, so screw 400 can be made not interfere with electric clearance, from
Without processing stator end very short, and then turn-to-turn short circuit ratio can be ensured, greatly improve the yield rate of stator.Cause
This, the grounding wire component mounting structure 10 of motor according to embodiments of the present invention has that not easy to slip teeth, connection is reliable, can reduce
The advantages that turn-to-turn short circuit ratio and stator defect rate.
Below with reference to the accompanying drawings grounding wire component mounting structure 10 according to the motor of the specific embodiment of the invention is described.
As depicted in figs. 1 and 2, the grounding wire component mounting structure 10 of motor according to embodiments of the present invention includes casing
100th, support plate 200 and grounding wire component 300.
Specifically, support plate 200 can be welded in the outside wall surface of casing 100, it is possible thereby to which support plate 200 is fixed on into machine
On shell 100, and both firm and reliable connections.
Further, the screw mounting hole is flanging bore, so can be in the situation for the thickness for not increasing support plate 200
Under, increase the length of fit of the screw mounting hole and screw 400, so as to avoid sliding tooth, improve grounding wire component 300 and support plate
Reliability after 200 installations.
In some specific examples of the present invention, as depicted in figs. 1 and 2, support plate 200 includes two connecting portions 210, two
Supporting part 220 and an installation portion 230.
Two connecting portions 210 are welded in the outside wall surface of casing 100 and are spaced apart and set.Two supporting parts 220 respectively with
The two relative edges of two connecting portions 210 are connected.Installation portion 230 is connected with two supporting parts 220 respectively, and installation portion 230 exists
Outside wall surface under the support of two supporting parts 220 with casing 100 is spaced apart, and the screw mounting hole is located on installation portion 230, is connect
Ground wire component 300 is arranged on by screw 400 on the surface of the remote casing 100 of installation portion 230.It so can both ensure screw
400 have larger length of fit with the screw mounting hole, can prevent screw 400 from being interfered with casing 100 again.
Specifically, as depicted in figs. 1 and 2, two connecting portions 210 are welded on the periphery wall of casing 100, two connections
Portion 210 is in parallel to each other along the axially extending of casing 100, and two connecting portions 210 are put along circumferentially-spaced open up of casing 100.
Therefore without bending connecting portion 210, so that it may so that connecting portion 210 adapts to the radian of the outer peripheral face of casing 100, so as to not only can be with
Facilitate the welding of connecting portion 210 and the periphery wall of casing 100, and the reliability after both weld can be improved.
Further, two supporting parts 220 are in parallel to each other along the axially extending of casing 100, and two supporting parts 220 with
Angle between the connecting portion 210 being connected is equal.That is, between a supporting part 220 and the connecting portion 210 being connected
Angle is equal to the angle between another supporting part 220 and the connecting portion 210 being connected.It is possible thereby to make the stress of support plate 200 equal
Even distribution, so as to improve the intensity of support plate 200.
In some specific embodiments of the present invention, 230, two supporting parts 220 of installation portion and two connecting portions 210 are one
Body part.In other words, support plate 200 is formed by an entire plate bending.It is possible thereby to ensure the structural strength of support plate 200.
Advantageously, as shown in Fig. 2 installation portion 230 divides with the junction of two supporting parts 220 and two supporting parts 220
Not with the equal arc transition in junction of two connecting portions 210.It can so avoid occurring stress concentration phenomenon on support plate 200, from
And the bearing capacity of support plate 200 can be improved.
