Description
Technical field
The present invention relates to comprise the hermetic compressor that is arranged on the insulation component on the stator winding.
Background technology
For example the stator of the motor of the hermetic compressor of refrigerator will be through will being placed into by the winding that lead constitutes in the slit on the stator heap that is made up of magnetic sheet to be used for refrigerating plant, and winding forms the parts that are called as the winding head through the opposite face that extends through the stator heap laterally.And the mechanical organ that the metal compressor block is placed on the stator and the compressor block carrying is basic in hermetic compressor is such as cylinder, piston, crank and piston rod.Compressor block is arranged to the stator heap and goes up to be positioned at the top of winding head.For security reasons, the space of minimum 2mm will be stayed between compressor block and the winding head, so that when electric current is applied to stator winding, between winding wire and body, do not have electric current transition (electric leakage).In order to form said space, stator winding is pressed with the specified pressure that will form.In most of the cases, the number needs of stator winding will be increased the efficient that is used for air compressor motor and play positive influences; But need stay the quantity that safe space between compressor block and the winding suppressed winding increases.In order to address this problem; In the prior art; By having thickness is that the insulation component that the leptophragmata of 0.15-0.20mm is processed from plastic film is set between stator winding head and the compressor block, has produced particularly because the problem aspect the labour of the form generation of winding head and compressor block but these insulation components are put into air compressor motor.
In International Patent Application WO 2008145760, the insulation component that is rotated between coil core and the winding head has been described.This insulation component comprises the additional insulation extension of the flange extension that is placed on the peripheral edge regions on the coil core and cylinder casing is provided and the insulation between the winding head.
In U.S. Pat 5957671; Film in the stator of the motor that is used to compressor has been described; It provides the insulation between winding head and the compressor block, utilizes the opening that is arranged in the center through pushing on the intracardiac strutting piece that attaches it to compressor block.
Summary of the invention
The objective of the invention is to realize a kind of hermetic compressor, it comprises can be placed to the insulation component on the stator winding with easily installing.
Be implemented and be used to reach the object of the invention and comprise: stator with stator heap at the hermetic compressor of first claim and corresponding claim explanation thereof; The winding that is made up of lead is placed on the stator heap; The winding head of the part that the upper surface that the formation winding is piled from stator extends laterally; And be placed in the compressor block on the upper surface of stator heap, and be made of plastics and be installed in annular (ring-type) insulation component on the winding head.
Vertical section with insulation component of annular body be downwards towards C shape, insulation component has the groove that is arranged on wherein, and the winding head is arranged in the groove.
In an embodiment of the present invention, insulation component is processed by heat-shrinkage material.In this embodiment, insulation component shrinks owing to being heated after on being mounted to the winding head, is bonded on the winding head and through the shape that adopts the winding head and obtains permanent connection.
In another embodiment of the present invention, insulation component has the opening that forms through a part of cutting away circumferential body, and the electrical connection of the winding head that can realize extending laterally from the winding head.Since opening be oriented to compressor block on recess aims at, the location that does not therefore have the winding head to be provided with at opening contacts the risk of compressor block.
Insulation component is assembled to the winding head, because its annular of surrounding winding as sleeve is easily mounted on the winding head and through covering the winding head insulation is provided.At insulation component with the lash rope that need winding not kept together on the winding head on it.

Embodiment
Be suitable for comprising shell 2 at the hermetic compressor 1 that refrigerating plant for example uses in the refrigerator; Be positioned at the stator 5 of shell 2; Has 3 and one in stator heap constituting by lamination or more than one winding 4; Winding 4 is made up of the lead on the slit that is wrapped on the stator heap 3; Form part that winding 4 extends from the opposite face of stator heap 3 laterally more than one winding head 6, and carry and/or support the for example compressor block 7 of cylinder, piston, crank and piston rod of basic mechanical organ, be installed on the upside of stator heap 3 so that its lower surface does not contact the upside of winding head 6.
Hermetic compressor 1 of the present invention comprises annular (ring-type) insulation component 10, is processed by plastic material, is installed on the winding head 6 and as sleeve and surrounds winding head 6.
The arm of the main body 8 of groove 9 through stretch forming C shape makes and moves away each other and enlarged insulation component 10 being mounted to winding head 6, and insulation component 10 is installed on the winding head 6 through utilizing easy hand labour in axial direction to push.
In one embodiment of the invention, insulation component 10 is processed by heat-shrinkage material.
In this embodiment, after insulation component 10 was mounted to winding head 6, stator 5 was placed in the heating furnace, and its temperature is conditioned and is used for this operation and insulation component 10 is heated.Owing to add the shape that thermal insulation element 10 is bonded to winding 4 through contraction and adopts winding head 6, and obtain permanent connection.
In one embodiment of the invention; Insulation component 10 comprises the opening 11 that forms through a part of excising main body 8; And when insulation component 10 is mounted to winding head 6, the electrical connection of its end through aiming at the winding of realizing extending laterally from winding head 64 with the part of the electrical connection of the end that forms winding 4.
In this embodiment, insulation component 10 does not cover winding head 6 in opening 11 residing location.The end of extending winding 4 through the winding head 6 from opening 11 residing location laterally forms electrical connection.And one or be arranged on the compressor block 7 to reduce the weight of material more than one recess G; As before embodiment shown in; Because opening 11 is aimed at recess G on the compressor block 7, so there is not the risk of the winding head 6 of compressor block 7 contact openings 11 residing location.
Be appreciated that the present invention limits and those skilled in the art can introduce various embodiment easily through top disclosed embodiment.These embodiment should be taken into account in by claim of the present invention and require in the scope of protection.
