The power cord 03 and the stator lead 04 use the same connector, and finally are fastened by a nut 05, a bolt 06 and a spring washer. After the stator wiring 04 is connected to the power cord 03, it exits, so the space for the connector of the power cord 03 and fasteners such as the nut 05 needs to be reserved in the height direction. In this way, the wiring process is complex and error-prone, and at the same time, the volume occupied by the wiring board 01 is relatively large. Summary of the Utility Model

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation on the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0042] As Figures 4 to 9 shown, the embodiment of the present utility model provides a wiring component. The wiring component has a first mounting surface 10 and a second mounting surface 20. The first mounting surface 10 and the second mounting surface 20 are perpendicular to each other. The first mounting surface 10 has a plurality of first wiring terminals 11, and the plurality of first wiring terminals 11 are distributed along a first direction. The second mounting surface 20 has a plurality of second wiring terminals 21, and the plurality of second wiring terminals 21 are distributed along a second direction. The first wiring terminals 11 and the second wiring terminals 21 are connected in one-to-one correspondence along the distribution direction. The first wiring terminals 11 are used to be electrically connected to the stator 300 of the motor, and the second wiring terminals 21 are electrically connected to the power supply. The first direction and the second direction have an included angle. In this application, the power supply is a three-phase power supply. In this embodiment, the distribution direction can be the distribution direction of the first wiring terminals 11 or the distribution direction of the second wiring terminals 21.

[0043] Applying the technical solution of the present utility model, the first wiring terminals 11 are used to be electrically connected to the stator of the motor, the second wiring terminals 21 are electrically connected to the power supply, and the first wiring terminals 11 and the second wiring terminals 21 are connected in one-to-one correspondence along the distribution direction. In this way, the power supply wiring and the stator wiring do not need to use the same connector, which is convenient for disassembling and connecting the stator wiring, the power supply wiring and the wiring component separately at any time. The occurrence of wiring errors is reduced, the convenience of wiring operation is improved, and at the same time, the number of fasteners and the space volume of the wiring component are reduced. The plurality of first wiring terminals 11 are distributed along a first direction, the plurality of second wiring terminals 21 are distributed along a second direction, and the first direction and the second direction have an included angle. This enables the wiring directions of the first wiring terminals 11 and the second wiring terminals 21 to be parallel to each other, perpendicular to each other, or have an included angle, increasing the flexibility of wiring of the wiring component. In this way, the wiring component can adjust the wiring direction according to different working conditions, can meet more wiring requirements to adapt to different types of motors, and improves the applicability and practicality of the wiring component. And it can also minimize the bending of the cables, further reduce the space volume required by the wiring component, and then can increase the space occupancy of the iron core in the motor and improve the output power of the motor.

[0044] In this application, an included angle may exist between the first direction and the second direction in the horizontal plane, and an included angle may also exist between the first direction and the second direction in the vertical direction. Specifically, in this embodiment, as Figure 3 shown, the X-axis direction is the first direction, and the Y-axis is the second direction, and an included angle exists between the first direction and the second direction in the horizontal plane.

[0045] In this application, no specific arrangement direction is defined for the multiple first connection terminals 11 and the multiple second connection terminals 21. They may be arranged in a straight line or distributed along a curve.

[0046] Among them, the connection member includes a housing 30 and a plurality of connection tubes 40. The plurality of connection tubes 40 are located inside the housing 30. The housing 30 has a first mounting surface 10 and a second mounting surface 20. Both ends of the connection tube 40 respectively form a first connection terminal 11 and a second connection terminal 21. With such a setting, the structure is simple and convenient for processing. The housing 30 can protect the connection tubes 40, and integrating the connection tubes 40 inside the housing 30 reduces the space volume of the connection member.

[0047] In this application, the number of the connection tubes 40 is not limited and may be 2, 5, 8, etc. In this embodiment, the connection tubes 40 are arranged in three.

[0048] Among them, the connection tube 40 is made of a metal material, which can ensure the electrical connection between the first connection terminal 11 and the second connection terminal 21. In this way, the connection tube 40 can conduct electricity, enabling the current to smoothly pass from the power source through the second connection terminal 21, through the connection tube 40, and then through the first connection terminal 11 to flow to the stator 300 of the motor.

[0049] Furthermore, the housing 30 is made of an insulating material to ensure the insulation of the housing 30 of the connection member and avoid electrical accidents. In this application, the housing 30 is made of a resin material and wraps the connection tubes 40 by injection molding. The resin material has good insulation performance and low cost. In this application, the specific material of the connection tubes 40 is not limited and may be nickel, iron, cobalt, etc. Preferably, the connection tubes 40 are made of copper material, and copper has good electrical conductivity and thermal conductivity compared with other metals and is relatively inexpensive.

[0050] As Figures 5 to 8 shown, the connection tube 40 has a first section 41 and a second section 42 arranged in sequence. The first section 41 and the second section 42 are perpendicular to each other. The first section 41 has the first connection terminal 11, and the second section 42 has the second connection terminal 21. With such a setting, the structure is simple and convenient for the connection terminals outside the connection member to be connected to the first connection terminal 11 and the second connection terminal 21 through connection posts.

[0051] Specifically, the housing 30 has oppositely arranged side surfaces and end surfaces. The side surfaces form the first mounting surface 10, and the end surfaces form the second mounting surface 20. In this way, the first mounting surface 10 and the second mounting surface 20 are not in the same plane, which can prevent the winding between different cables when the first terminal 11 and the second terminal 21 are wired, and prevent the wiring on the wiring component from being chaotic, thus affecting the current conduction effect.

[0052] Compared with the prior art, since the power cord 03 and the stator lead 04 are at 90°, in the existing industry, the wiring board 01 uses a 45° wiring post wiring method to take into account the installation of the stator wire and the customer wire. However, due to the inclined setting of the wiring head 02 of this wiring board 01, when the stator lead 04 passes through, the one connected to the one close to the iron core 07 needs to be bent. Especially for the motor with the maximum power of the same frame number, the stack height of its iron core 07 is relatively high, and the end height already occupies the outgoing line space of the junction box, resulting in a serious compression of the stator outgoing line space. However, the position of the wiring board 01 remains fixed. Therefore, the one connected to the innermost side needs to be bent towards the side close to the iron core 07 and then enter the junction box for wiring. The bending degree is relatively large, and the cable is easily damaged over time. For the wiring component provided in this application, after the wiring of the stator 300 is taken out, it does not need to be bent towards the direction of the stator 300, but directly accesses the side of the wiring component, parallel to the end of the stator 300, reducing the bending degree during wiring of the cable, extending the service life of the cable. At the same time, since the cable does not need a large bend, the required space of the junction box 200 is reduced, the space occupancy ratio of the stator 300 is increased, and the housing of the motor is effectively utilized, and a higher power can be output.

[0053] Among them, the shape of the cross-section of the wiring component is not limited. It can be set as a triangle, a rectangle or other shapes.

[0054] In this embodiment, the first direction and the second direction have an included angle on the horizontal plane, and the cross-section of the wiring component in the top view is a triangle, so that the volume of the wiring board can be further reduced.

[0055] In other embodiments of the present application, the first direction and the second direction have an included angle on the vertical plane, the cross-section of the wiring component in the top view is a rectangle, and the second mounting surface 20 is inclined towards the bottom surface of the wiring component.

[0056] Among them, there is a convex portion 31 on the end surface. The top surface of the convex portion 31 forms the second mounting surface 20. The second section 42 extends into the convex portion 31 and passes out through the top surface of the convex portion 31. Through the above settings, the distance between the first terminal 11 and the second terminal 21 is further increased, and at the same time, it is convenient to distinguish the first terminal 11 and the second terminal 21, avoiding wiring errors during wiring, and reducing the situation of cable winding between the first terminal 11 and the second terminal 21.

[0057] In this solution, the inner walls of the first terminal 11 and the second terminal 21 have threaded sections. With such a setting, the wiring of the wiring component can be completed by the threaded fit of the fastener 50 and the threaded section, which has a simple structure and is convenient for processing. Moreover, the threaded structure fit can also increase the tightness and reliability of the contact between the terminal and the inner walls of the first terminal 11 and the second terminal 21.

[0058] When wiring, directly pass the fastener 50 through the wiring terminals of the power supply and the stator and then screw it into the first terminal 11 and the second terminal 21 to complete the wiring. The above design has a simple structure, is convenient for disassembly and assembly, and can also be adjusted according to wiring terminals of different sizes. While ensuring the stability during wiring, it improves the convenience and flexibility of wiring and also saves production costs. Specifically, the fastener 50 can be a screw.

[0059] In other embodiments of the present application, it is possible to choose to process the threaded section only inside the first terminal 11, or only inside the second terminal 21.

[0060] Specifically, an anti-slip structure is provided between the wiring tube 40 and the housing 30 to prevent relative displacement between the wiring tube 40 and the housing 30 during use, which may affect the operation of the motor.

[0061] In this embodiment, the specific structure of the anti-slip structure is not limited. A viscous layer can be added between the wiring tube 40 and the housing 30, or the roughness of the contact surface between the housing 30 and the wiring tube 40 can be increased.

[0062] As Figure 7 and Figure 8 shown, an anti-slip protrusion 43 is provided on the outer periphery of the wiring tube 40, and an anti-slip groove is provided inside the housing 30. The anti-slip protrusion 43 and the anti-slip groove cooperate to form an anti-slip structure. Through the above setting, the contact area between the wiring tube 40 and the housing 30 can be increased. At the same time, the cooperation between the anti-slip protrusion 43 and the anti-slip groove can also limit the relative position of the wiring tube 40 and the housing 30, improving the reliability and stability of the connection between the wiring tube 40 and the housing 30.

[0063] In other embodiments of the present application, multiple anti-slip protrusions 43 can be provided inside the housing 30, and multiple anti-slip grooves can be provided on the outer periphery of the wiring tube 40.

[0064] Specifically, in this embodiment, the number and arrangement of the anti-slip protrusions 43 are not limited. It can be multiple or single. When there are multiple anti-slip protrusions 43, they can be arranged circumferentially or at circumferential intervals along the wiring tube 40, or can be arranged in a spiral around the outer periphery of the wiring tube 40. Or the anti-slip protrusions 43 are arranged disorderly on the outer periphery of the wiring tube 40.

[0065] Specifically, the lengths of the multiple wiring tubes 40 gradually increase along the distribution direction. Such a setting can enable the lengths of the wiring tubes 40 to adapt to the sizes of the wiring components, avoiding the situation where the wiring tubes 40 are too long and penetrate through the wiring components, resulting in too large sizes of the wiring components or interference with the wiring. It can also avoid the situation where the wiring tubes 40 are too short and cause wiring difficulties.

[0066] In another embodiment of the present application, a motor is provided. The motor includes: a housing 100, a junction box 200, a wiring component, and a driving part. Among them, the housing 100 has a receiving cavity. The junction box 200 is disposed above the housing 100. The wiring component is the wiring component in the above embodiment, and the wiring component is located in the junction box 200. As Figure 9 and Figure 5 shown, the driving part is disposed in the receiving cavity. The driving part includes a rotor and a stator 300. The stator 300 is wound around the outer periphery of the rotor, and the stator 300 is electrically connected to the first wiring end 11 of the wiring component. The junction box 200 has a power supply wiring port 201, and the wiring terminal of the power supply enters the junction box 200 from the power supply wiring port 201. The above wiring component can effectively solve the problems of complex wiring of the wiring board and excessive bending degree of the cable in the prior art. By setting an included angle between the distribution directions of the first wiring end 11 and the second wiring end 21, the flexibility of wiring is improved, the space volume of the motor occupied by the wiring component is reduced, and the space utilization rate of the motor is increased. The motor with the above wiring component also has the above advantages.

[0067] Among them, the motor in the present application is an industrial motor. In other embodiments of the present application, the motor can also be applied in other fields, such as the new energy field, etc. The connection modes of the wiring terminals with the first wiring end 11 and the second wiring end 21 can be adjusted according to the wiring requirements.
