Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is described in further detail.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, not
For limiting the present invention.
With reference to Fig. 1 and Fig. 2, the invention discloses a kind of plastic packaging stator, including thermal protector 41, it is electrically connected with thermal protector 41
The combined stator connect, the thermal protector 41 that surface is covered with elastic protecting sleeve 45 are fixed in the combined stator slot of combined stator,
Elastic protecting sleeve 45 is made of electrically conductive material, and heat can be transmitted by elastic protecting sleeve, to guarantee to be arranged
It will not influence the normal on-off of thermal protector after protective case.The reason of elastic protecting sleeve 45 are arranged is: due to thermal protector needs
It places in combined stator slot, and has enameled wire in combined stator slot, in order to avoid heat protector outer casing squeezes enameled wire of damaging, because
This must be using the high temperature resistant protective case softer with elasticity.In addition, it is necessary to explanation, the shell of thermal protector ontology cannot
Elasticity is directly designed to compared with softwood matter, otherwise the chip in thermal protector can be deformed in injection molding by plastic packaging material pinch shock, very
To causing motor to be scrapped, therefore elastic protecting sleeve 45 can only be set in the outer surface of thermal protector.
The detailed construction of combined stator is, combined stator include stator core 1, be wound on stator core 1 yoke portion winding
3, it is mounted on the skeleton 2 at 1 both ends of stator core, the region on stator core 1 between two neighboring teeth portion is combined stator slot 5,
Thermal protector 41 is fixedly mounted in one of combined stator slot 5, and thermal protector 41 is mounted in combined stator slot 5, is stablized
Property is more preferably.
Thermal protector 41 is equipped with the interior connecting lead wire 46 for being electrically connected combined stator, and interior connecting lead wire 46 is fixedly mounted on
