The third groove 150 can be wound around the winding 220, so that the winding 220 is stably connected to the crimping portion 144, and then the winding 220 can be crimped onto the wiring portion 140 by applying a force to the crimping portion 144.

[0093] like Figure 3 As shown, in some embodiments of the present invention, optionally, there are multiple first grooves 142 , and the multiple first grooves 142 are located on two opposite sides of the wiring portion 140 .

[0094] In this embodiment, there are multiple first grooves 142, and the multiple first grooves 142 are located on two opposite sides of the wiring portion 140. The multiple first grooves 142 can all be used for winding. The winding 220 has grooves on both sides of the wiring portion 140 for winding. The winding 220 has a target position during winding, which reduces the difficulty of winding. The limiting function of the multiple first grooves 142 can effectively improve the stability of the winding 220 during setting.

[0095] like Figure 3 As shown, in some embodiments of the present invention, the wiring component 130 further includes: a bending portion 152 , which is connected to the mounting portion 132 and is located on a side of the mounting portion 132 away from the connecting portion 134 , and an angle is formed between the bending portion 152 and the mounting portion 132 .

[0096] In this embodiment, the wiring component 130 specifically also includes a bending portion 152, which is connected to the mounting portion 132 and is located on a side of the mounting portion 132 away from the connecting portion 134. An angle is formed between the bending portion 152 and the mounting portion 132. The bending portion 152 can be snapped onto the mounting portion 132 through the above-mentioned angle, thereby preventing the connecting portion 134 from falling off and improving the stability of the connection.

[0097] Specifically, the bending portion 152 and the mounting portion 132 are an integrated structure, thereby further improving the connection stability between the bending portion 152 and the mounting portion 132.

[0098] Figure 4 The structure diagram of the stator assembly in one embodiment of the utility model is shown. Figure 5 FIG. 1 shows a schematic diagram of a structure in which a stator assembly and a wiring assembly are connected in one embodiment of the utility model. Figure 4 and Figure 5 As shown, in one embodiment of the present invention, the present invention further provides a motor, which includes a wiring assembly 100 as in any of the above embodiments.

[0099] In this embodiment, the motor provided by the present invention comprises the terminal assembly 100 as in any of the above embodiments, and thus has all the beneficial effects of the terminal assembly 100 of the first aspect.

[0100] On the other hand, the wiring assembly 100 proposed in the present invention can also be used in a compressor, and the compressor includes the wiring assembly 100 or the motor proposed in the present invention.

[0101] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, optionally, the motor further includes a stator assembly 200, and the stator assembly 200 further includes a molded part 230 and a buckle 240, the molded part 230 is connected to the stator core 210, and the buckle 240 is connected to the molded part 230 and is clamped on the base 110.

[0102] The overmolded part 230 plays the role of insulation and protection. By connecting the overmolded part 230 with the stator core 210 , the overmolded part 230 wraps the stator core 210 , thereby improving insulation reliability.

[0103] The buckle 240 is connected to the overmolded part 230 and is clipped onto the base 110. The base 110 and the overmolded part 230 can be connected relatively easily through the buckle 240. The overmolded part 230 and the base 110 cooperate to form a secondary insulation structure, which can completely avoid direct contact between the stator core 210 and the winding 220, thereby maintaining good insulation between the winding 220 and the stator core 210.

[0104] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, optionally, the base 110 is provided with a plurality of fourth grooves 112 , the plurality of fourth grooves 112 are arranged along the circumference of the base 110 , and the plurality of fourth grooves 112 are asymmetric relative to the axis of the stator assembly 200 ; the buckle 240 is located in the fourth groove 112 .

[0105] In the embodiment, a plurality of fourth grooves 112 are provided on the base 110 . The fourth grooves 112 are specifically components for installing the base 110 . The buckles 240 are located in the fourth grooves 112 .

[0106] Regarding the specific distribution form of the plurality of fourth grooves 112, the utility model sets the plurality of fourth grooves 112 along the circumference of the base 110 ( Figure 1 The fourth grooves 112 are arranged in a direction indicated by the indicator line B in FIG. 1 , and the plurality of fourth grooves 112 are asymmetric relative to the axis of the stator assembly 200.

[0107] The utility model can achieve the uniqueness of the installation position and improve the accuracy of the circumferential positioning by setting an asymmetric installation structure along the circumferential arrangement of the base 110, so that when the base 110 is connected to the overmolded part 230 through the buckle 240, on the one hand, the connection between the two is more stable, and on the other hand, the two can accurately form an insulating structure between the stator core 210 and the winding 220, which can completely avoid direct contact between the stator core 210 and the winding 220, thereby maintaining good insulation between the winding 220 and the stator core 210.

[0108] Specifically, the buckle 240 includes a body, which is connected to the overmolded component 230 , and a guiding inclined surface is provided on the body so that the buckle can slide into the fourth groove 112 provided on the base 110 .

[0109] Specifically, there are multiple clips 240 , and the number of the clips 240 corresponds to the number of the fourth grooves 112 , and one clip 240 is clipped into one fourth groove 112 , thereby improving the connection stability and connection accuracy between the overmolded part 230 and the base 110 .

[0110] like Figure 1 , Figure 4 and Figure 5As shown, in some embodiments of the present invention, optionally, the widths of the plurality of fourth grooves 112 in the circumferential direction of the stator assembly 200 are different; and / or the distances between the plurality of adjacent groups of fourth grooves 112 in the circumferential direction of the stator assembly 200 are different.

[0111] In this embodiment, the fourth groove 112 is arranged to form an asymmetric structure. On the one hand, the widths of the plurality of fourth grooves 112 in the circumferential direction of the stator assembly 200 are different, thereby making the plurality of fourth grooves 112 asymmetric relative to the axis of the stator assembly 200, thereby achieving the uniqueness of the installation position and improving the accuracy of the circumferential positioning. In addition, since only the width of the fourth groove 112 in the circumferential direction of the stator assembly 200 is set, the difficulty of forming an asymmetric positioning structure can be reduced.

[0112] On the other hand, the distances between multiple groups of adjacent fourth grooves 112 in the circumferential direction of the stator assembly 200 are different, thereby making the multiple fourth grooves 112 asymmetric relative to the axis of the stator assembly 200, thereby achieving the uniqueness of the installation position and improving the accuracy of circumferential positioning. In addition, since only the distance between the fourth grooves 112 in the circumferential direction of the stator assembly 200 is set, the difficulty of forming an asymmetric positioning structure can be reduced.

[0113] On the other hand, the widths of the multiple fourth grooves 112 in the circumferential direction of the stator assembly 200 are different, and the distances between multiple groups of adjacent fourth grooves 112 in the circumferential direction of the stator assembly 200 are different, thereby making the multiple fourth grooves 112 asymmetric relative to the axis of the stator assembly 200, achieving the uniqueness of the installation position and improving the accuracy of circumferential positioning. Moreover, since the widths and distances of the multiple fourth grooves 112 in the circumferential direction of the stator assembly 200 are different, the complexity of the formed asymmetric structure can be increased, thereby further improving the accuracy of circumferential positioning.

[0114] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, optionally, the base 110 is provided with a positioning hole 118 , and the stator assembly 200 further includes: a positioning column 260 , which is connected to the overmolded component 230 and is penetrated into the positioning hole 118 .

[0115] In this embodiment, the utility model is provided with a positioning hole 118 on the base 110. In addition, the stator assembly 200 is provided with a positioning column 260, which is connected to the overmolding 230 and is penetrated in the positioning hole 118. Through the combined connection of the positioning column 260 and the positioning hole 118, the circumferential positioning of the base 110 and the overmolding 230 can be achieved when they are connected, so that the connection position of the two is accurate, and an insulation barrier can be formed between the stator core 210 and the winding 220 to avoid direct contact between the stator core 210 and the winding 220.

[0116] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, optionally, the base 110 includes a first positioning platform 116, and the positioning hole 118 is arranged on the first positioning platform 116; the stator assembly 200 also includes a second positioning platform 250, the first side 146 of the second positioning platform 250 is connected to the overmolded part 230, and the positioning column 260 is arranged on the second side 148 of the second positioning platform 250; the side of the first positioning platform 116 close to the stator assembly 200 is in contact with the second side 148 of the second positioning platform 250.

[0117] In this embodiment, the base 110 specifically includes a first positioning platform 116 , and the positioning hole 118 is disposed on the first positioning platform 116 to facilitate the opening of the positioning hole 118 .

[0118] The stator assembly 200 further includes a second positioning platform 250 , a first side 146 of which is connected to the overmolded component 230 , and a positioning post 260 is disposed on a second side 148 of the second positioning platform 250 , thereby achieving connection between the positioning post 260 and the overmolded component 230 .

[0119] The side of the first positioning platform 116 close to the stator assembly 200 is connected to the second side 148 of the second positioning platform 250. During the positioning connection, the connection between the first positioning platform 116 and the second positioning platform 250 can realize the axial positioning when the base 110 and the overmolded part 230 are connected.

[0120] In one implementation of the present utility model, Figure 5 As shown, when the wiring assembly 100 proposed by the utility model is used in a motor, the overmolded part 230 is arranged on one side of the stator core 210 in the axial direction for lead winding. After the stator core 210 and the overmolded part 230 are wound, the three-phase U, V, and W input terminals are led out separately, and the three-phase U, V, and W output terminals are led out collectively.

[0121] In the present invention, the plurality of fourth grooves 112 disposed on the base plate 114 of the wiring assembly 100 are asymmetric with respect to the axis of the stator assembly 200 and correspond to the buckles 240 of the stator assembly 200 , and the positioning holes 118 on the first positioning platform 116 included in the base 110 correspond to the positioning columns 260 of the stator assembly 200 .

[0122] The non-centrosymmetrical fourth groove 112 of the present invention is provided to ensure the uniqueness of the angular orientation of the installation position of the wiring assembly 100 .

[0123] After the buckle 240 is aligned with the fourth groove 112 and the positioning hole 118 is aligned with the positioning column 260, the wiring assembly 100 is pressed down slightly, the fourth groove 112 slides along the guide slope on the buckle 240, the buckle 240 enters the fourth groove 112, and the buckle 240 and the fourth groove 112 are connected. At the same time, the positioning column 260 is also synchronously inserted into the positioning hole 118 to achieve circumferential positioning of the stator assembly 200 and the wiring assembly 100. The side of the first positioning platform 116 close to the stator assembly 200 contacts the second side 148 of the second positioning platform 250. Axial positioning of the stator assembly 200 and the wiring assembly 100 is achieved.

[0124] The three-phase U, V, and W input terminals are independent of each other, and the output terminals are concentrated for the N phase and are led out from the second grooves 122 at the corresponding positions, pass through the notches of the first groove 142 and the third groove 150 in sequence, and are wound several turns on the crimping portion 144 where the third groove 150 is set to complete the initial fixation.

[0125] The crimping part 144 is pressed, so that the second side 148 of the crimping part 144, i.e., the free side, moves toward the wiring part 140. The crimping part 144 and the wiring part 140 squeeze the winding wire, fix the several turns of lead wire wound thereon, and perform resistance welding near the clamping opening. The lead wire of the winding 220 is fixed on the wiring assembly 100. The resistance welding process destroys the surface paint coating of the lead wire, and the lead wire of the winding 220 is connected to the wiring part 140.

[0126] The mounting portion 132 is connected to the wiring portion 140 and the connecting portion 134 , and its end is connected to a bending portion 152 , which is encapsulated in the fixing portion 120 , and can better reduce the influence of the heat generated during the resistance welding process on the bonding strength between the wiring component 130 and the substrate 110 .

[0127] The second end 138 of the connecting portion 134 extends away from the stator core 210 , and the head passes through the reserved hole of the electric control board, and is connected by welding or plug-in structure. At this point, the stator assembly 200 and the electric control board are relatively fixed and effectively connected.

[0128] The motor proposed in the utility model can not only isolate and insulate the stator assembly 200 and the electric control board in the axial direction, but also is easy and efficient to assemble and install. The position is fixed after installation, the welding can be easily automated, the one-piece injection molding structure is firm, the resistance welding time is short, the heat generated during the welding process is relatively controllable, and the welding reliability is high.

[0129] By setting the base 110 of the specific wiring component 130 on the first axial side 146 of the stator core 210 of the stator assembly 200 of the motor, not only the coil winding is insulated, but also the winding and slot structure welding are carried out through the second groove 122, i.e. the lead groove, set on the base 110 and the first groove 142 and the third groove 150, i.e. the winding groove, set on the wiring part 140. Through heat conduction and the solidification of the solder, the solder column can be evenly distributed on the surface of the slot body. In this way, the winding 220 and the wiring component 130 can be fastened, so that the winding 220 is not easy to fall off.

[0130] The utility model configures the wiring component 130 to have a connected welding part and a plug-in part, and is integrally injection-molded in the substrate 114. The length of the substrate 114 wrapping the mounting part 132 can be adjusted according to the length of the connecting part 134 to prevent the connecting part 134 from being easily loosened from the substrate 114. This structure is suitable for application scenarios with different lengths of the connecting part 134 (the distance between the stator assembly 200 and the electric control board), which broadens the scope of application. The buckle 240 is snap-connected with the base 110 to achieve the fixation of the stator assembly 200 and the wiring assembly 100.
