Description

Technical Field

[0001] The present invention belongs to the technical field of stators, and in particular relates to a stator end plate, a stator, a motor, a compressor and a processing method of the stator. Background Art

[0002] At present, the stator output of the variable frequency motor adopts the "riveting" process. The "riveting" process simplifies the process route. At the same time, the riveting terminals and wire binding are automatically completed by the equipment, which greatly reduces manual work in the process, reduces labor costs, and improves the degree of automation and connection reliability.

[0003] However, after the terminals are automatically riveted, there are cases where the copper wire cannot be cut or the copper wire end retracts when the cutter cuts the copper wire, resulting in poor appearance or even connectivity failure. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, in the first aspect, the present invention proposes a stator end plate, comprising: an end plate, the end plate being provided with a wire groove, the wire groove being capable of being passed through by the wire harness in the motor; a support boss, provided on the outer periphery of the end plate, the support boss being used to support the wire harness extending out of the wire groove.

[0006] The end plate is usually installed on the axial side of the stator core. The wire slots on the end plate are used to pass the wiring harness in the power supply, for example, the wiring harness includes the stator coil and lead wires. The portion of the wiring harness that passes through the wire slot and extends radially outward from the end plate needs to be cut off. If the wiring harness is in a suspended state, due to the good toughness of copper wire, aluminum wire, etc., under uneven force, slight wear of the cutter blade, or increased cutting knife gap, the copper wire or aluminum wire will be pulled downward during the cutting process, causing the wire end to undergo a brief elastic deformation, resulting in the wiring harness being unable to be effectively cut. Alternatively, the wire end will deform and rebound at the moment of cutting, which will manifest as the wire end section being retracted into the terminal box instead of outside the terminal box. In severe cases, it may even pop out from the inner diameter side of the terminal box, causing the circuit to fail.

[0007] The above problems with cutting wire harnesses are essentially caused by the fact that the wire ends are very tough but have no support, which causes them to deform under stress. Therefore, the above problems can be solved by providing support for the wire harness during the process of being cut.

[0008] In this solution, a support boss is provided on the outer periphery of the end plate. When the wire harness passes through the wire groove and extends to the radially outer side of the end plate, the support boss can be used to support the wire harness. When the cutter cuts off excess wire harness, the cutter can fall on the support boss. In the process of cutting the wire harness, since the support boss supports the wire harness, the wire harness can be prevented from being pulled downward by the cutter, and the wire harness can be prevented from being deformed by being pulled, ensuring that the wire harness can be effectively cut off, and preventing the problem of deformation and rebound after the wire harness is cut off, thereby effectively preventing the problem of circuit conduction failure.

[0009] In some technical solutions, optionally, along the axial direction of the end plate, a wire groove opening is provided on the first side of the end plate, the distance between the second side of the end plate and the bottom of the wire groove is L1, and the maximum distance between the second side of the end plate and the supporting boss is L2, L2≤L1.

[0010] The opening of the wire trough is located on the first side of the end plate, and the distance between the bottom of the wire trough and the second side of the end plate is L1. One surface of the support boss is named the first surface. The first surface is a surface of the support boss facing away from the second side of the end plate. The maximum distance between the second side of the end plate and the support boss is the distance between the second side of the end plate and the first surface. The maximum distance between the second side of the end plate and the support boss is L2. Since L2≤L1, the support boss is not higher than the bottom of the wire trough, that is, the support boss is flush with the bottom of the wire trough, or the support boss is lower than the bottom of the wire trough. The support boss does not block the wire trough. This method can ensure that the support boss can more conveniently support the wiring harness.

[0011] In some technical solutions, optionally, the support boss is flush with the second side of the end plate; or along the axial direction of the end plate, the support boss is located between the first side of the end plate and the second side of the end plate.

[0012] The supporting boss does not extend beyond the second side of the end plate, thereby avoiding interference between the supporting boss and the stator core and ensuring stable installation of the end plate.

[0013] In some technical solutions, optionally, along the circumference of the end plate, the two sides of the support boss are aligned with the two sides of the wire groove; or along the circumference of the end plate, the extension lines of the two sides of the support boss are L3 and L4 respectively, and the wire groove is located between L3 and L4.

[0014] The two sides of the support boss align with the two sides of the wire trough, so that the wire harness extending out of the wire trough can be fully supported by the support boss, improving the convenience of cutting out excess wire harness. Alternatively, the width of the support boss can be greater than the width of the wire trough, so that the two sides of the support boss extend out of the side of the wire trough. This method can also ensure that the support boss fully supports the wire harness.

[0015] In some technical solutions, optionally, the end plate includes: an end plate body; a terminal box, which is arranged on the end plate body, and the number of terminal boxes is multiple, and the multiple terminal boxes are distributed at intervals along the circumference of the end plate body, and at least three wire grooves are provided on the terminal box, and at least three support bosses are provided on any terminal box, and two adjacent support bosses are arranged at intervals.

[0016] A plurality of terminal boxes are arranged in the circumferential direction of the end plate body, and at least three wire slots are arranged on each terminal box. At least three wire slots of some terminal boxes may all be provided with wire harnesses, and at least three wire slots of some terminal boxes may only be provided with wire harnesses in some of the slots. However, in order to facilitate processing and production, the plurality of terminal boxes on the end plate body may be arranged to have the same structure, that is, the plurality of terminal boxes have the same number of wire slots and the same structure, thereby reducing the processing difficulty of the stator end plate.

[0017] At least three supporting bosses are provided on each terminal box. The number of supporting bosses may be the same as or different from the number of wire troughs. However, the number of supporting bosses should be at least equal to the number of wire troughs to ensure that the wire harness extending from each wire trough can be effectively supported.

[0018] In some technical solutions, optionally, the support boss is provided with a first support plane, the first support plane is used to support the wire harness, and the first support plane is in contact with the bottom of the wire trough; or the support boss is provided with a first support curved surface, the first support curved surface is used to support the wire harness, and the first support curved surface is in contact with the bottom of the wire trough.

[0019] The surface of the supporting boss supporting the wire harness can be set as a plane, that is, the supporting boss sets a first supporting plane. When the excess wire harness is cut, the first supporting plane supports the wire harness to ensure that the wire harness can be cut smoothly.

[0020] Alternatively, the surface of the support boss supporting the wire harness can be configured as a curved surface, that is, the support boss can be configured as a first supporting curved surface. The bottom of the wire trough can also be configured as a curved surface, so that the bottom of the wire trough can limit the movement of the wire harness. The first supporting curved surface and the bottom of the wire trough coincide radially, that is, the shape of the first supporting curved surface is the same as the shape of the bottom of the wire trough. The wire harness extending from the wire trough can be stably accommodated within the first supporting curved surface, ensuring stability during cutting of the wire harness.

[0021] In some technical solutions, optionally, the support boss extends along the axial direction of the end plate body, and the thickness of the support boss protruding from the surface of the end plate body is H1, 0mm

[0022] ​If the thickness of the support boss is too large, the support boss may interfere with other structures in the motor. In this solution, the thickness of the support boss is limited to less than or equal to 3 mm. Within this range, the support boss can support the wiring harness and avoid interference between the support boss and other structures.

[0023] The support boss extends along the axial direction of the end plate body, so that the support boss and the end plate have a larger contact area, and the support boss is not easily separated from the end plate, ensuring that the support boss can stably support the wire harness.

[0024] In some technical solutions, optionally, the width of the supporting boss is W, 1mm≤W≤3mm.

[0025] If the width of the support boss is too small, the support boss cannot fully support the wiring harness. If the width of the support boss is too large, the weight of the support boss is large, which causes the weight of the entire stator end plate to be large. In order to reduce the weight of the stator end plate, the width of the support boss in this solution is less than or equal to 3 mm.

[0026] In some technical solutions, optionally, the thickness of the supporting boss protruding from the surface of the end plate body is H2, 0.3mm≤H2≤2.5mm.

[0027] If the support boss is too thin, the cutter may have difficulty landing on its surface. If it is too thick, it may interfere with other structures in the motor. This solution limits the thickness of the support boss to between 0.3mm and 2.5mm. This allows the support boss to effectively cooperate with the cutter, support the wiring harness, and prevent interference with other structures.

[0028] In some technical solutions, optionally, the end plate includes: an end plate body and a terminal box, the terminal box is arranged on the end plate body, the number of the terminal boxes is multiple, and the multiple terminal boxes are distributed at intervals along the circumference of the end plate body. At least three wire grooves are arranged on the terminal box along the circumference of the end plate body, and the support boss passes through at least three wire grooves.

[0029] The support boss extends along the width direction of the terminal box and passes through at least three wire troughs. In this case, one support boss can support the wire harnesses extending from at least three wire troughs, so there is no need to set up multiple support bosses, reducing the processing difficulty of the terminal box.

[0030] In some technical solutions, optionally, the thickness of the supporting boss protruding from the surface of the end plate body is H3, 0.5mm≤H3≤3mm.

[0031] If the support boss is too thin, the cutter may have difficulty landing on its surface. If it is too thick, it may interfere with other structures in the motor. This solution limits the thickness of the support boss to between 0.5mm and 3mm. This allows the support boss to effectively cooperate with the cutter, support the wiring harness, and prevent interference with other structures.

[0032] In some technical solutions, optionally, in the circumferential direction of the end plate body, the supporting boss is located between the two side edges of the terminal box.

[0033] The supporting boss extends along the width direction of the terminal box and does not extend beyond the side of the terminal box, thereby avoiding interference between the supporting boss and other structures outside the terminal box.

[0034] In some technical solutions, optionally, the support boss is provided with a second support plane, the second support plane is used to support the wire harness, and the second support plane is in contact with the bottom of the wire trough; or the support boss is provided with at least two second support curved surfaces, the second support curved surfaces are used to support the wire harness, and the second support curved surfaces are in contact with the bottom of the wire trough.

[0035] The surface of the supporting boss supporting the wire harness can be set as a plane, that is, the supporting boss sets a first supporting plane. When the excess wire harness is cut, the first supporting plane supports the wire harness to ensure that the wire harness can be cut smoothly.

[0036] Alternatively, a portion of the surface of the supporting boss that supports the wire harness can be set as a curved surface, and at least a portion of the curved surface radially overlaps with the bottom of the wire groove. The wire harness extending out of the wire groove can be stably accommodated in the first supporting curved surface to ensure stability when the wire harness is cut.

[0037] For example, when there are three wire grooves, the surfaces of the supporting boss corresponding to the two side wire grooves can be set as curved surfaces, and the surface of the supporting boss corresponding to the middle wire groove can be set as a flat surface.

[0038] In some technical solutions, optionally, a hollow hole is provided on the supporting boss, and the hollow hole extends along the axial direction of the end plate body.

[0039] A hollow hole is provided on the supporting boss, and the hollow hole can reduce the weight of the supporting boss, thereby reducing the influence of the supporting boss on the overall weight of the stator end plate.

[0040] In some technical solutions, optionally, the stator end plate further includes: a blade terminal, a connecting groove is provided on the end plate, at least three wire slots are connected through the connecting groove, the blade terminal is plugged into the connecting groove, and the blade terminal is used to connect the wire harnesses in at least three wire slots.

[0041] The blade-shaped terminal can cut the insulating wire skin on the surface of the wire harness, so that the wire harnesses in at least three wire grooves are connected through the blade-shaped terminal.

[0042] In a second aspect, the present invention proposes a stator comprising: a stator core; a wiring harness comprising a stator coil and lead wires; and a stator end plate such as the stator end plate in the first aspect, the stator end plate being arranged on one side of the stator core in the axial direction, and the stator coil and lead wires being passed through wire slots.

[0043] In a third aspect, the present invention provides a motor, comprising: the stator in the second aspect.

[0044] In a fourth aspect, the present invention provides a compressor, comprising: the motor in the third aspect.

[0045] In a fifth aspect, the present invention proposes a method for processing a stator, comprising: passing a wire harness through a wire slot on an end plate; placing a portion of the wire harness extending out of the wire slot on a supporting boss, and cutting off a portion of the wire harness extending out of the wire slot with a cutter.

[0046] In some technical solutions, the end plate optionally includes: an end plate body and a terminal box, the terminal box being disposed on the end plate body. There are multiple terminal boxes, spaced apart along the circumference of the end plate body. The terminal boxes are provided with at least three wire slots, and each terminal box is provided with at least three support bosses, with adjacent support bosses spaced apart. The support bosses protrude from the surface of the end plate body by a thickness H2, where 0.3 mm ≤ H2 ≤ 2.5 mm. The stator processing method further includes: removing the support bosses with a cutter while removing the wiring harness.

[0047] The thickness of the support boss protruding from the surface of the end plate body is between 0.3mm and 2.5mm, and at least three support bosses are set at intervals. In order to avoid the problem of the support boss falling off during the subsequent operation of the motor, this solution stipulates that when cutting off the excess wiring harness, the support boss is directly cut off to avoid the normal operation of the motor being affected by the falling off of the support boss during subsequent use.

[0048] For the support boss extending in the axial direction and the support boss extending in the width direction of the terminal box, since the support boss has a large contact area with the terminal box, the support boss is not easy to fall off, so there is no need to cut off the support boss in these two cases.

DETAILED DESCRIPTION

[0074] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0075] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0076] Refer to the following Figures 1 to 21 The present invention describes a stator end plate, a stator, a motor, a compressor, and a method for manufacturing a stator according to some embodiments of the present invention.

[0077] Combine Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in some embodiments of the present invention, a stator end plate 200 is proposed, which includes: an end plate 210 and a support boss 220. The end plate 210 is provided with a wire groove 211, and the wire groove 211 can be passed through by the wire harness 120 in the motor. The support boss 220 is provided on the outer periphery of the end plate 210, and the support boss 220 is used to support the wire harness 120 extending out of the wire groove 211.

[0078] The end plate 210 is usually installed on one axial side of the stator core 110. The wire slot 211 on the end plate 210 is used to allow the wire harness 120 in the power supply to pass through. For example, the wire harness 120 includes a stator coil 121 and a lead wire 122. A portion of the wire harness 120 that passes through the wire slot 211 and extends radially outward from the end plate 210 needs to be cut off. If the wire harness 120 is in a suspended state, due to the good toughness of copper wire, aluminum wire, etc., under uneven force, slight wear of the cutter blade, or increased cutting knife gap, the copper wire or aluminum wire will be pulled downward during the cutting process, causing the wire end to undergo temporary elastic deformation, resulting in the wire harness 120 being unable to be effectively cut. Alternatively, the wire end will deform and rebound at the moment of cutting, which is manifested as the wire end section being retracted into the terminal box 215 instead of outside the terminal box 215. In severe cases, it may even pop out from the inner diameter side of the terminal box 215, causing circuit conduction failure.

[0079] The above problems with cutting the wire harness 120 are essentially caused by the fact that the wire ends are very tough but have no support, which causes them to deform under stress. Therefore, the above problems can be solved by providing support to the wire harness 120 during the process of being cut under stress.

[0080] In this solution, a support boss 220 is provided on the outer periphery of the end plate 210. When the wire harness 120 passes through the wire groove 211 and extends to the radially outer side of the end plate 210, the support boss 220 can be used to support the wire harness 120. When the cutter cuts off excess wire harness 120, the cutter can fall on the support boss 220. In the process of cutting the wire harness 120, since the support boss 220 supports the wire harness 120, the wire harness 120 can be prevented from being pulled downward by the cutter, and the wire harness 120 can be prevented from being pulled and deformed, ensuring that the wire harness 120 can be effectively cut off, and preventing the wire harness 120 from deforming and rebounding after being cut, thereby effectively preventing the problem of circuit conduction failure.

[0081] Combine Figure 3 and Figure 12 As shown, in some embodiments, optionally, along the axial direction ( Figure 3 The arrow at H in the middle points to the direction), the first side of the end plate 210 is provided with an opening 212 of the wire groove 211, the distance between the second side of the end plate 210 and the groove bottom 213 of the wire groove 211 is L1, and the maximum distance between the second side of the end plate 210 and the supporting boss 220 is L2, L2≤L1.

[0082] The opening 212 of the wire trough 211 is located on the first side of the end plate 210, and the distance between the bottom 213 of the wire trough 211 and the second side of the end plate 210 is L1. A surface of the support boss 220 is named the first surface. The first surface is a surface of the support boss 220 that faces away from the second side of the end plate 210. The maximum distance between the second side of the end plate 210 and the support boss 220 is the distance between the second side of the end plate 210 and the first surface. The maximum distance between the second side of the end plate 210 and the support boss 220 is L2. Since L2≤L1, the support boss 220 is not higher than the bottom 213 of the wire trough 211, that is, the support boss 220 is flush with the bottom 213 of the wire trough 211, or the support boss 220 is lower than the bottom 213 of the wire trough 211. The support boss 220 does not block the wire trough 211. This method can ensure that the support boss 220 can more conveniently support the wiring harness 120.

[0083] Combine Figure 6 and Figure 12 As shown, in some embodiments, optionally, the support boss 220 is flush with the second side of the end plate 210 , or, along the axial direction of the end plate 210 , the support boss 220 is located between the first side of the end plate 210 and the second side of the end plate 210 .

[0084] The support boss 220 does not extend beyond the second side of the end plate 210 , thereby preventing interference between the support boss 220 and the stator core 110 and ensuring stable installation of the end plate 210 .

[0085] Combine Figure 3 and Figure 12 As shown, in some embodiments, optionally, along the circumference of the end plate 210 ( Figure 3 (As indicated by the arrow at C in the middle), the two sides of the support boss 220 are aligned with the two sides of the wire groove 211, or, along the circumference of the end plate 210, the extension lines of the two sides of the support boss 220 are L3 and L4, respectively, and the wire groove 211 is located between L3 and L4.

[0086] The two sides of the support boss 220 are aligned with the two sides of the wire groove 211, so that the wire harness 120 extending out of the wire groove 211 can be fully supported by the support boss 220, improving the convenience when removing excess wire harness 120. Alternatively, the width of the support boss 220 can be greater than the width of the wire groove 211, so that the two sides of the support boss 220 extend out of the side of the wire groove 211. This method can also ensure that the support boss 220 fully supports the wire harness 120.

[0087] Combine Figure 2 、 Figure 3 and Figure 10As shown, in some embodiments, optionally, the end plate 210 includes: an end plate body 214 and a terminal box 215, the terminal box 215 is arranged on the end plate body 214, the number of the terminal boxes 215 is multiple, and the multiple terminal boxes 215 are distributed at intervals along the circumference of the end plate body 214, at least three wire grooves 211 are provided on the terminal box 215, and at least three support bosses 220 are provided on any terminal box 215, and two adjacent support bosses 220 are arranged at intervals.

[0088] A plurality of terminal boxes 215 are arranged in the circumferential direction of the end plate body 214, and at least three wire slots 211 are arranged on each terminal box 215. At least three wire slots 211 of some terminal boxes 215 may all be provided with wiring harnesses 120, and at least three wire slots 211 of some terminal boxes 215 may only be provided with wiring harnesses 120 in some wire slots 211. However, in order to facilitate processing and production, the plurality of terminal boxes 215 on the end plate body 214 may be set to the same structure, that is, the plurality of terminal boxes 215 have the same number and structure of wire slots 211, thereby reducing the processing difficulty of the stator end plate 200.

[0089] At least three support bosses 220 are provided on each terminal box 215. The number of support bosses 220 may be the same as or different from the number of wire troughs 211. However, the number of support bosses 220 should be at least equal to the number of wire troughs 211, thereby ensuring that the wiring harness 120 extending from each wire trough 211 can be effectively supported.

[0090] Combine Figure 6 、 Figure 9 、 Figure 12 and Figure 13 As shown, in some embodiments, optionally, the support boss 220 is provided with a first support plane 221, the first support plane 221 is used to support the wire harness 120, and the first support plane 221 is in contact with the bottom 213 of the wire trough 211. Alternatively, the support boss 220 is provided with a first support curved surface 222, the first support curved surface 222 is used to support the wire harness 120, and the first support curved surface 222 is in contact with the bottom of the wire trough.

[0091] The surface of the support boss 220 that supports the wire harness 120 can be set as a plane. That is, the support boss 220 is provided with a first support plane 221. When the excess wire harness 120 is cut, the first support plane 221 supports the wire harness 120, ensuring that the wire harness 120 can be cut smoothly. In this embodiment, the first support plane 221 is parallel to the radial direction of the end plate body 214 and perpendicular to the axial direction of the end plate body 214.

[0092] Alternatively, the surface of the support boss 220 that supports the wire harness 120 can be set as a curved surface, that is, the support boss 220 is provided with a first supporting curved surface 222. In this embodiment, the groove bottom 213 of the wire groove 211 is a curved surface, and the first supporting curved surface 222 and the groove bottom 213 coincide with each other in the radial direction of the end plate body 214, so that the groove bottom 213 of the wire groove 211 can limit the movement of the wire harness 120. The first supporting curved surface 222 and the groove bottom 213 of the wire groove 211 coincide in the radial direction, that is, the shape of the first supporting curved surface 222 is the same as the shape of the groove bottom 213 of the wire groove 211. The wire harness 120 extending out of the wire groove 211 can be stably accommodated within the first supporting curved surface 222, ensuring stability when the wire harness 120 is cut.

[0093] like Figure 11 As shown, in some embodiments, optionally, the support boss 220 extends along the axial direction of the end plate body 214, and the thickness of the support boss 220 protruding from the surface of the end plate body 214 is H1, 0mm

[0094] If the thickness of the support boss 220 is too large, the support boss 220 may interfere with other structures in the motor. In this solution, the thickness of the support boss 220 is limited to less than or equal to 3 mm. Within this range, the support boss 220 can support the wiring harness 120 and avoid interference between the support boss 220 and other structures.

[0095] The support boss 220 extends axially along the end plate body 214 , so that the support boss 220 and the end plate 210 have a larger contact area. The support boss 220 is not easily separated from the end plate 210 , ensuring that the support boss 220 can stably support the wire harness 120 .

[0096] In some embodiments, optionally, the width of the supporting boss 220 is W, 1 mm ≤ W ≤ 3 mm.

[0097] When the width of the support boss 220 is too small, the support boss 220 cannot fully support the wiring harness 120. When the width of the support boss 220 is too large, the weight of the support boss 220 is large, thereby causing the weight of the entire stator end plate 200 to be large. In order to reduce the weight of the stator end plate 200, the width of the support boss 220 in this solution is less than or equal to 3 mm.

[0098] ​After the automatic riveting terminal machine presses the plug-in piercing terminal into the terminal box 215, the cutter is pressed down to cut off the excess wire ends. Since the wire ends at the terminal box 215 are perpendicular to the central axis of the stator core 110 and the incision is on the outer circumferential surface of the end plate 210, considering that the electrical safety distance must be guaranteed, the wire ends extending outward from the end plate 210 cannot be too long. This also requires that the blade of the knife is very close to the outer circumferential surface of the end plate 210 when the cutter falls, that is, it is approximately in a fitted state. At the same time, because the copper wire / aluminum wire has good toughness and plasticity, it is easy to bend and deform under stress. Therefore, at the moment the cutter falls, the copper wire / aluminum wire extending outward from the terminal box 215 is forced to bend downward, and the blade will roughly split along the axial center of the copper wire / aluminum wire, resulting in a phenomenon of continuous cutting.

[0099] When the cutter is in close contact with the outer surface of the terminal box 215 and the cutter is slightly worn, the blade pulls the copper wire / aluminum wire to elastically deform at the moment it falls, and it rebounds instantly after being cut, causing the wire head on the outside of the end plate 210 to retract into the terminal box 215 or even pop out of the terminal, returning to the state of disconnected circuit before crimping.

[0100] When the cutter cuts through the iron core / aluminum wire, the problem of the wire ends not being able to cut through or retracting is ultimately due to the significant macroscopic deformation of the wire ends during the force applied. Therefore, the purpose of this embodiment is to prevent the wire ends from undergoing macroscopic deformation during the cutting process. To achieve this goal, this embodiment provides a solution by adding a support boss 220 to each copper wire end.

[0101] The position of the support boss 220 is to add a cylindrical support boss 220 below each wire slot 211 on the outer ring terminal box 215 of the end plate 210. The upper plane of the support boss 220 remains horizontal, and the upper plane of the support boss 220 is tangent to the bottom semicircle of the wire slot 211, or the upper end face of the support boss 220 is a U-shaped surface, which coincides with the U-shaped surface at the bottom of the wire slot 211. The support boss 220 is a fixed part of the end plate 210.

[0102] The shape of the support boss 220 is not limited to a square column, but can also be other shapes. However, no matter what other shapes the support boss 220 has, as long as it plays the same role as this embodiment, it is within the scope of protection of this embodiment.

[0103] The dimensions of the support boss 220 are such that, in the axial direction of the end plate 210, the upper surface of the support boss 220 or the bottom of the U-shaped portion of the support boss 220 must not be higher than the bottom of the wire trough 211, and must not extend downward beyond the lower surface of the end plate 210. Each support boss 220 has a total width of 1 mm to 3 mm in the left-right direction, centered on the centerline of the corresponding wire trough 211. In the diameter direction of the end plate 210, the support boss 220 protrudes from the outer surface of the terminal box 215 by a height of 0 mm to 3 mm.

[0104] After adding the support boss 220, the support boss 220 can hold the wire ends on the outside of the end plate 210. When the cutter falls, the copper wire / aluminum wire will not bend, deform, or move significantly at the cutting edge due to the support and fixation of the support boss 220. Technical problems such as the wire ends not being split and cut and the wire ends being indented are also solved.

[0105] In some embodiments, optionally, the thickness of the support boss 220 protruding from the surface of the end plate body 214 is H2, 0.3 mm ≤ H2 ≤ 2.5 mm.

[0106] If the thickness of the support boss 220 is too small, the cutter may have difficulty landing on the surface of the support boss 220. If the thickness of the support boss 220 is too large, the support boss 220 may interfere with other structures in the motor. In this solution, the thickness of the support boss 220 is limited to between 0.3 mm and 2.5 mm. This allows the support boss 220 to effectively cooperate with the cutter, support the wiring harness 120, and prevent interference between the support boss 220 and other structures.

[0107] This embodiment discloses a stator end plate 200 used in a rotary variable frequency compressor, specifically a method for supporting the riveted metal monolithic terminal outlet ends of a concentrated winding motor stator, and a compressor motor stator having an assembly made using this method, wherein the outlet ends are copper enameled wires, aluminum enameled wires or copper-aluminum composite enameled wires, the number of outlet ends is 6 or more, and the terminals are metal monolithic terminals. Taking the riveting of 6 outgoing wire ends as an example, the 3 outgoing wire ends of the three groups of coils on the motor stator are placed in the three wire slots 211 of the same terminal box 215 in sequence, the 3 incoming wire ends of the three groups of coils on the motor stator are placed in the wire slots 211 on the same side of the remaining 3 terminal boxes 215 in sequence, and the 3 outgoing wire ends of the lead wire 122 are placed in the wire slots 211 on the other side of the 3 terminal boxes 215 in sequence. All the wire ends outside the wire slots 211 are placed on the support boss 220. After the metal single-piece terminal is riveted into the terminal box 215, the wire cutter is pressed down to use the support boss 220 as an "anvil" to cut off the excess wire ends. The support boss 220 is a fixed part fixed at the outside of the terminal box 215 on the end plate 210. Each terminal box 215 contains 3 wire slots 211, and each wire slot 211 matches 1 support boss 220. Figure 12 、 Figure 13 and Figure 14 As shown, the shape of the support boss 220 is fixed as a flat surface or a U-shaped surface that wraps the outlet head except for the side that contacts the outlet head. The shapes of the other side surfaces are not limited. The shapes of different support bosses 220 of the same terminal box 215 can be freely combined.

[0108] The technical solution provided in this embodiment is intended to solve the problem of the wire ends not being cut off when the riveted metal single-piece terminal of the rotary compressor motor stator is cut, and the technical problem of the connection failure caused by the indentation of the wire ends.

[0109] Taking the 9-slot concentrated winding star series connection motor stator of a rotary variable frequency compressor as an example, there are 6 coil outlets. According to the star wiring method, the common end is 3 outlets, which are respectively inserted into the three wire slots 211 of a terminal box 215, and the other 3 outlets are respectively inserted into the wire slots 211 on the same side of the remaining three terminal boxes 215 in turn. Then, the 3 outlets of the lead wire 122 are respectively inserted into the wire slots 211 on the other side of the front three terminal boxes 215 in turn. At this time, the distribution and placement of the outlets are completed. Then, external pressure is used to press the metal single-piece terminal vertically into the terminal box 215, and then the cutting knife is pressed down to cut the wire end. During this process, since the copper wire, especially the aluminum wire, has good toughness, when the force is uneven, the blade of the wire end cutting knife is slightly worn, or the gap between the cutting knife becomes larger, the copper wire / aluminum wire will be pulled downward during the cutting process, causing the wire end to undergo a brief elastic deformation. At the moment of cutting, the wire end deforms and rebounds, which is manifested as the wire end cross section being indented instead of being outside the terminal box 215. In severe cases, the metal single-piece terminal wire slot 211 may even pop out from the inner diameter side of the terminal box 215, causing the circuit to fail.

[0110] In summary, the above-mentioned problems with cut ends are essentially caused by the fact that the thread ends are very tough but have no support, which causes them to deform under stress. The targeted solution is to provide support for the thread ends during the process of being cut, which is the thread end support method described in the present invention.

[0111] Combine Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, each terminal box 215 has a supporting boss 220 on the outside of the bottom of the wire trough 211. The shape of the supporting boss 220 is not limited and can be square, convex semicircular, circular at the top and bottom, concave at the top and square at the bottom, or other shapes, or a combination of different shapes.

[0112] It should be noted that, in this embodiment, the 9-slot concentrated winding star series connection motor stator of the rotary variable frequency compressor is taken as an example, where "9 slots" means the number of holes on the stator core 110, and can also be 12 slots, 15 slots, or 18 slots. In this embodiment, only 9 slots are used as a specific embodiment. The meaning of "star series connection" is to ensure that there are 6 coil output wires, 3 common ends and 1 coil output wire each connected to the three-color lead wire 122, which matches the 4 terminal boxes 215 of the specific embodiment. In this embodiment, the number of terminal boxes 215 may not be limited to 4, and the corresponding wiring method may not be limited to the star series connection. The meaning of "outlet head" may be copper enameled wire, aluminum enameled wire, or copper-aluminum composite enameled wire.

[0113] In the description of this embodiment, the support boss 220 means the convex point on the end plate 210 outside the wire groove 211 of the terminal box 215, which is used to place the wire end before and after the stator coil 121 output wire is cut off. The shape of the support boss 220 requires that the side in contact with the output wire is a flat surface or a U-shaped surface that wraps the output wire end. The shape of the other sides is not limited to the several embodiments in this embodiment, and the three support bosses 220 on the outside of the same terminal box 215 can have different shapes. The number of support bosses 220 is related to the terminals used in the stator 100, specifically 3 times the number of terminals used, for example 12, 15, etc.

[0114] In the supporting method of this embodiment, the support bosses 220 are removed together with the terminal ends during the trimming process after the crimping is complete. The support bosses 220 on the outside of the same terminal box 215 are removed simultaneously, regardless of the order in which they are removed. The support bosses 220 on the outside of different terminal boxes 215 can be removed simultaneously or sequentially.

[0115] In this embodiment, the stator 100 includes six lead wires (stator coils 121) and four terminal boxes 215. Three of the lead wires are connected by blade terminals 230 to form a common terminal. The remaining three lead wires are connected to the red, black, and white lead wires 122 by metal monolithic terminals to form the three external wires of the stator 100. The bottom outer sides of the wire slots 211 of each of the four terminal boxes 215 have three square support bosses 220. The support method of this embodiment is not limited to the several forms shown in the drawings. Other variations can be freely combined with the specific embodiments of this embodiment on the same terminal box 215. All combinations are variations of the support method of this embodiment and are within the scope of protection of this application.

[0116] Combine Figure 15 and Figure 16In some embodiments, optionally, the end plate 210 includes: an end plate body 214 and a terminal box 215, the terminal box 215 is arranged on the end plate body 214, the number of the terminal boxes 215 is multiple, and the multiple terminal boxes 215 are distributed at intervals along the circumference of the end plate body 214, and at least three wire grooves 211 are provided on the terminal box 215 along the circumference of the end plate body 214, and the support boss 220 passes through at least three wire grooves 211.

[0117] The support boss 220 extends along the width direction of the terminal box 215, and the support boss 220 passes through at least three wire grooves 211. In this case, one support boss 220 can support the wire harness 120 extending from at least three wire grooves 211, so there is no need to set up multiple support bosses 220, reducing the processing difficulty of the terminal box 215.

[0118] In some embodiments, optionally, the thickness of the support boss 220 protruding from the surface of the end plate body 214 is H3, and 0.5 mm ≤ H3 ≤ 3 mm.

[0119] If the thickness of the support boss 220 is too small, the cutter may have difficulty landing on the surface of the support boss 220. If the thickness of the support boss 220 is too large, the support boss 220 may interfere with other structures in the motor. In this solution, the thickness of the support boss 220 is limited to between 0.5 mm and 3 mm. This allows the support boss 220 to effectively cooperate with the cutter, support the wiring harness 120, and prevent interference between the support boss 220 and other structures.

[0120] Combine Figure 16 and Figure 17 As shown, in some embodiments, optionally, in the circumferential direction of the end plate body 214 , the support boss 220 is located between the two side edges of the terminal box 215 .

[0121] The support boss 220 extends along the width direction of the terminal box 215 and does not extend out of the side of the terminal box 215 , thereby preventing the support boss 220 from interfering with other structures outside the terminal box 215 .

[0122] Combine Figure 19 and Figure 20 As shown, in some embodiments, optionally, the support boss 220 is provided with a second support plane 223, the second support plane 223 is used to support the wiring harness 120, and the second support plane 223 is in contact with the bottom 213 of the wire trough 211; or, the support boss 220 is provided with at least two second support curved surfaces 224, the second support curved surfaces 224 are used to support the wiring harness 120, and the second support curved surfaces 224 are in contact with the bottom 213 of the wire trough 211.

[0123] The surface of the support boss 220 supporting the wire harness 120 can be set as a plane, that is, the support boss 220 is provided with a first support plane 221. When the excess wire harness 120 is cut, the first support plane 221 supports the wire harness 120, ensuring that the wire harness 120 can be cut smoothly. In this embodiment, the second support plane 223 is parallel to the radial direction of the end plate body 214 ( Figure 3 The arrow at R in the figure points to ) and is perpendicular to the axial direction of the end plate body 214.

[0124] Alternatively, a portion of the surface of the support boss 220 that supports the wire harness 120 can be set as a curved surface. In this embodiment, the bottom 213 of the wire groove 211 is a curved surface, and at least a portion of the second supporting curved surface 224 coincides with the bottom 213 in the radial direction of the end plate body 214. The wire harness 120 extending out of the wire groove 211 can be stably accommodated in the first supporting curved surface 222, ensuring stability when the wire harness 120 is cut.

[0125] For example, Figure 9 As shown, when there are three wire grooves 211 , the surfaces of the supporting boss 220 corresponding to the two side wire grooves 211 can be set as curved surfaces, and the surface of the supporting boss 220 corresponding to the middle wire groove 211 can be flat.

[0126] like Figure 18 As shown, in some embodiments, optionally, a hollow hole 225 is provided on the support boss 220 , and the hollow hole 225 extends along the axial direction of the end plate body 214 .

[0127] A hollow hole 225 is provided on the support boss 220 , and the hollow hole 225 can reduce the weight of the support boss 220 , thereby reducing the influence of the support boss 220 on the overall weight of the stator end plate 200 .

[0128] Combine Figure 3 and Figure 5 As shown, in some embodiments, optionally, the stator end plate 200 further includes: a blade terminal 230, a connecting groove 231 is provided on the end plate 210, at least three wire grooves 211 are connected through the connecting groove 231, and the blade terminal 230 is plugged into the connecting groove 231, and the blade terminal 230 is used to connect the wiring harness 120 in at least three wire grooves 211.

[0129] The blade terminals 230 can cut through the insulation covering the surface of the wire harness 120 , thereby connecting the wire harnesses 120 in at least three wire slots 211 through the blade terminals 230 .

[0130] When the cutter cuts through the iron core / aluminum wire, the problem of the wire end not being able to cut through or retracting is ultimately due to the significant macroscopic deformation of the wire end during the force applied. Therefore, the purpose of this embodiment is to prevent this macroscopic deformation of the wire end during the cutting process. To achieve this goal, this embodiment provides a solution by adding a support boss 220 to the copper / aluminum wire.

[0131] The support boss 220 is located below the three wire ducts 211 on the outer terminal box 215 of the end plate 210. A stepped support boss 220 is added, with its upper surface tangent to the bottom semicircle of the wire duct 211. Two top views of the support boss 220 are available: one solid and one hollow. The support boss 220 is a fixed component of the end plate 210.

[0132] Combine Figure 17 、 Figure 18 、 Figure 19 、 Figure 20 and Figure 21 As shown, the front view of the support boss 220 is not limited to a regular rectangular parallelepiped; it can also have other shapes. Its top view can be solid or hollow. The overall shape of the support boss 220 can be freely combined with the front view and top view patterns. However, regardless of the shape of the support boss 220, as long as it achieves the same function as the method of this embodiment, it is within the scope of protection of this application.

[0133] As for the size of the support boss 220, in the axial direction of the end plate 210, it must not be higher than the bottom of the wire groove 211 upwards, and must not be lower than the bottom edge of the terminal box 215 downwards. The left and right widths of the support boss 220 must not exceed the left and right sides of the terminal box 215. The height in the normal direction of the center axis of the end plate 210 is between 0.5mm and 3mm.

[0134] A supporting boss 220 is added to hold the wire ends on the outside of the end plate 210. When the cutter falls, the copper wire / aluminum wire will not bend, deform, or move significantly at the cutting edge due to the support and fixation of the supporting boss 220. Technical problems such as the wire ends not being able to be split and cut and the wire ends being indented are also solved.

[0135] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in an embodiment of the present invention, a stator 100 is proposed, comprising: a stator core 110, a wiring harness 120 and a stator end plate 200 in any of the above embodiments, the wiring harness 120 comprises a stator coil 121 and a lead wire 122, the stator end plate 200 is arranged on one side of the stator core 110 in the axial direction, and the stator coil 121 and the lead wire 122 are passed through the wire slot 211.

[0136] The wiring harness 120 includes a stator coil 121 and a lead wire 122. A support boss 220 is provided on the periphery of the end plate 210. When the stator coil 121 and the lead wire 122 pass through the wire slot 211 and extend to the radially outer side of the end plate 210, the support boss 220 can be used to support the above-mentioned wiring harness 120. When the cutter cuts off excess wiring harness 120, the cutter can fall on the support boss 220. In the process of cutting the wiring harness 120, since the support boss 220 supports the wiring harness 120, the wiring harness 120 can be prevented from being pulled downward by the cutter, and the wiring harness 120 can be prevented from being pulled and deformed, ensuring that the wiring harness 120 can be effectively cut off, and preventing the wiring harness 120 from deforming and rebounding after being cut, thereby effectively preventing the occurrence of circuit conduction failure.

[0137] In an embodiment of the present invention, a motor is proposed, including the stator in the above embodiment. The motor in this embodiment can achieve the technical effects in any of the above embodiments, which will not be described in detail here.

[0138] In an embodiment of the present invention, a compressor is proposed, including the motor in the above embodiment, and the compressor in this embodiment can achieve the technical effects in any of the above embodiments, which will not be described in detail here.

[0139] In an embodiment of the present invention, a stator processing method is proposed, comprising: passing a wire harness through a wire slot on an end plate; placing a portion of the wire harness extending out of the wire slot on a supporting boss; and cutting off the portion of the wire harness extending out of the wire slot with a cutter.

[0140] In some embodiments, the end plate optionally includes: an end plate body and a terminal box, the terminal box being disposed on the end plate body. A plurality of terminal boxes are provided, the plurality of terminal boxes being spaced apart along the circumference of the end plate body. The terminal boxes are provided with at least three wire slots, and each terminal box is provided with at least three support bosses, with adjacent support bosses spaced apart. The thickness of the support bosses protruding from the surface of the end plate body is H2, with 0.3 mm ≤ H2 ≤ 2.5 mm. The stator processing method further includes: removing the support bosses with a cutter while removing the wiring harness.

[0141] The thickness of the support boss protruding from the surface of the end plate body is between 0.3mm and 2.5mm, and at least three support bosses are set at intervals. In order to avoid the problem of the support boss falling off during the subsequent operation of the motor, this solution stipulates that when cutting off the excess wiring harness, the support boss is directly cut off to avoid the normal operation of the motor being affected by the falling off of the support boss during subsequent use.

[0142] For the support boss extending in the axial direction and the support boss extending in the width direction of the terminal box, since the support boss has a large contact area with the terminal box, the support boss is not easy to fall off, so there is no need to cut off the support boss in these two cases.

[0143] In the present invention, the term "plurality" refers to two or more, unless otherwise specified. Terms such as "installed," "connected," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean fixed, removable, or integral; and "connected" can mean directly or indirectly through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0144] Throughout this specification, terms such as "one embodiment," "some embodiments," and "specific embodiments" mean that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0145] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
