Abstract

The utility model disclose a stator insulation framework which comprises an outer retaining ring and an inner retaining ring, wherein the outer retaining ring and the inner retaining ring are in circular shape and are connected by a plurality of wire winding parts. The wire winding parts comprise two side baffles which are at interval and a transverse baffle for connecting the upper ends of the two side bafflers. A plurality of outer insulation plates are arranged on the outer retaining ring which are at interval, a plurality of inner insulation plates are arranged on the inner retaining ring which are at interval, and an outer baffle and an inner baffle are respectively extended upward along the upper ends of the outer isolation plate and the inner isolation plate and projected on the outer surface of the transverse baffler. The utility model has the effect that two isolation frameworks using the above structure can be inserted from two sides of the stator, the two frameworks can be easily connected with the stator, thereby saving time and labor to assemble the stator, the frameworks can not be easily abrasion wear, and the isolation effect is improved greatly.

Description

The stator insulation skeleton

Technical field

The utility model relates to a kind of stator component, particularly relates to the insulation framework that is installed on the stator.

Background technology

Motor is made up of stator and two main parts of rotor, motor stator in the past is general to adopt slotting insulating paper to reach insulation, this structure needs the workman earlier the insulating paper foldable type, and then the insulating paper after the moulding is inserted in the groove of motor stator, wind the line on insulating paper, adopt this structure both to waste time and energy, insulation effect is bad again, it is damaged that insulating paper is subjected to friction easily, brings very big inconvenience more for the electric machine winding of back.

Summary of the invention

The utility model provides a kind of rational in infrastructure at above-mentioned the deficiencies in the prior art, can directly be inserted into time saving and energy saving in the stator slot, the stator insulation skeleton that insulation effect is good.

The technical solution of the utility model is achieved in that the stator insulation skeleton, this skeleton includes all rounded outer back-up ring and inner shield ring, described outer back-up ring is connected by several winding sections with inner shield ring, described winding section includes two side shields that keep at a certain distance away and the lagging that is connected two side shield upper ends, be distributed with the some blocks of external insulation plates that keep at a certain distance away each other outside on the back-up ring, on inner shield ring, be distributed with the some interior insulation boards that keep at a certain distance away each other, extend upward outer baffle and the Internal baffle that protrudes from the lagging outer surface respectively along the upper end of external insulation plate and interior insulation board.

As preferably, one end of described side shield connects the end of external insulation plate, the end of insulation board in the other end of side shield connects, an end of lagging connects the upper end of two adjacent external insulation plates, and the other end of lagging connects the upper end of two adjacent interior insulation boards.

As preferably, the centre of interior insulation board and Internal baffle be provided with one run through in the radial direction in the breach of insulation board and Internal baffle.

As preferably, be provided with groove in the centre of the inner surface of lagging.Described groove can make and leave certain slit between the Winding board surface of lagging and stator, and is for convenience detach.

As preferably, the width of described outer baffle is greater than the width of external insulation plate, and the width of described Internal baffle is greater than the width of interior insulation board.Thereby make coil windings and stator better isolate.

As preferably, the height of outer baffle is identical with the height of Internal baffle.

As preferably, be connected with a fixed head between two adjacent Internal baffles, the two ends, the left and right sides of fixed head connect the end of adjacent two Internal baffles respectively, and the bottom of fixed head connects lagging, and the height of fixed head is lower than the height of Internal baffle.Fixed head can increase the intensity of Internal baffle, makes Internal baffle firmer.

As preferably, be provided with in the radial direction a reinforcement in the centre of outer baffle.

Adopted the technique effect of the present utility model of technique scheme to be: can will adopt two insulation framework of said structure to insert from the both sides of stator respectively, two skeletons and stator are combined, insulation board, external insulation plate and the side shield of forming the winding section can be inserted in the groove between two adjacent wire-wrap boards of stator promptly, lagging pastes mutually with the upper and lower surface of wire-wrap board respectively, and then on the winding section winding around; Make that the assembling of stator was more time saving and energy saving, and be not easy wearing and tearing, insulation effect has also had large increase than before.
