2) for the neck portion described in by projection section into the first flange and the second flange, the second flange is provided with reinforcement, and second Flange is arranged on inside motor housing, and when lead wire bushing receives motor housing outside pulling force, reinforcement can be with reinforced leads The intensity of the flange of wire bushing second, it is not easy to deform, can prevent lead wire bushing from being released from motor housing.

3) neck portion is provided with reinforcement, can strengthen the intensity in neck portion, it is not easy to deforms, prevents lead wire bushing from electricity Released in machine shell.

4) reinforcement is located inside the second flange, and the surface of reinforcement is wrapped up by the second flange to be closed, and can prevent lead While wire bushing releases from motor housing, manufacturing process is simpler.

5) the reinforcement U-shaped profile described in, with neck portion form fit and being located inside neck portion, the table of reinforcement Face by neck portion wrap up close, can with the flange of reinforced leads wire bushing first, the second flange and the intensity in neck portion, no matter draw Line wire bushing be by what power, all do not allow it is yielding, so as to prevent lead wire bushing from being released from motor housing.

6) profile of reinforcement is annular or notched annular, the reinforcement of such profile and the boss of lead wire bushing The form fit in portion, anti-loose effect are more preferable.

7) reinforcement is made of metal, and intensity is strong, makes the intensity of lead wire bushing also stronger, more difficult deformation, from And it is more preferable to prevent that lead wire bushing from from motor housing releasing effect.

8) a kind of motor, including rotor assembly, stator module and shell, rotor assembly are nested in inside stator module, outside For valve jacket outside stator module, stator module includes coil windings, and lead is connected in coil windings, and shell is provided with fairlead, Lead wire bushing is housed, lead wire bushing includes neck portion, and shell is stuck in neck portion, and lead passes through lead wire bushing on fairlead It is connected with external power source, due to use lead wire bushing of the present utility model, the adhesion of lead wire bushing and motor housing is more It is good, released so as to be better protected from lead wire bushing from motor housing.
