[0042] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] A three-phase wire socket for motors, see Figure 1-2The three-phase wire seat is used as a wiring structure between the internal electrical connecting wires of the motor. The three-phase wire seat includes a connecting seat 11, a connecting hole 12, a positioning groove 13 and a connecting part 14. The connecting seat 11 is long and has three. The three connecting seats 11 are arranged at intervals and distributed in a triangular shape; the connecting hole 12 passes through the connecting seat 11 along the length direction of the connecting seat 11, and the connecting hole 12 is used for the passage of the electrical connecting wire; the positioning groove 13 is provided on the connecting seat 11 and is connected to one end of the connecting hole 12, and the positioning groove 13 is used for positioning and connecting the electrical connecting wire; the connecting part 14 is provided between adjacent connecting seats 11 and connects the three connecting seats 11 into a whole.

[0044] The above-mentioned scheme is adopted. This scheme has three connecting seats 11 and the three connecting seats 11 are arranged in a triangular shape. Since the connecting seat 11 is used for connection and positioning between electrical connection wires, the relative position relationship between the electrical connection wires is set to correspond one to one with the connecting seat 11, which can effectively improve the error-proofing effect during the installation of the electrical connection wires, and avoid the situation where the electrical connection wires are inserted into the wrong interface when installed on the three-phase wire seat, that is, it solves the problem of easy insertion into the wrong interface caused by the three-phase wire seat arranged in a straight line in the prior art; in addition, the present application uses the connecting hole 12 to assist the passage of the electrical connection wire, and uses the positioning groove 13 to position the connection position between the electrical connection wires, so as to improve the positioning effect and fixing effect of the installation of the electrical connection wire.

[0045] In the embodiment, the three connecting seats 11 are arranged in a triangular shape. The three connecting seats 11 can form an obtuse triangle, thereby avoiding the problem of being unable to prevent errors caused by the connecting seats 11 arranged in a straight line.

[0046] In one implementation, see Figure 1-2 The connection base 11 is cylindrical, and the positioning groove 13 is provided at one axial end of the connection base 11. The positioning groove 13 includes at least one plane parallel to the axial direction of the connection base 11. Thus, by providing at least one plane parallel to the axial direction of the connection base 11 on the positioning groove 13, the electrical connection wire is easily pressed and positioned on the plane, thereby achieving a positioning effect for the electrical connection wire.

[0047] In one implementation, see Figure 1-2 The positioning groove 13 is U-shaped along the radial section of the connecting base 11, and the bottom plane of the U-shape is parallel to the axial direction of the connecting base 11. In this way, the positioning groove 13 is U-shaped, and the bottom plane of the U-shaped positioning groove 13 is parallel to the axial direction of the connecting base 11, which facilitates the electrical connection wire to extend from the axial direction of the connecting base 11 and then abut against the bottom surface of the U-shape for positioning.

[0048] In one implementation, see Figure 3-5Along the radial cross-section of the connector 11, the location where the positioning groove 13 connects with the communication hole 12 is a flat hole. Thus, since the electrical connection wire will pass through the communication hole 12 and extend to the location of the positioning groove 13, the location where the positioning groove 13 connects with the communication hole 12 is a flat hole. This has the effect of positioning the electrical connection wire, reducing the shaking of the electrical connection wire and providing an anti-vibration effect. In addition, the flat hole has a positioning effect on the extension direction of the electrical connection wire, and thus the flat hole also has the effect of preventing oblique insertion, thereby preventing the electrical connection wire from being inserted obliquely.

[0049] In one implementation, see Figure 5 The bottom of the U-shaped positioning groove 13 is parallel to the long side of the flat hole, and the two side walls of the positioning groove 13 are perpendicular to the long side of the flat hole. In this way, the bottom surface and two side surfaces of the U-shaped positioning groove 13 serve as positioning surfaces, thereby assisting in the connection and positioning of the electrical connection wires.

[0050] In one implementation, see Figure 1-3 The connection base 11 further includes a connection hole 15, which is opened along the radial direction of the connection base 11 and is provided on the plane of the positioning groove 13. In this way, the connection hole 15 is provided, and the two electrical connection wires connected at the positioning groove 13 are fixed by connecting the connection hole 15 with a bolt or the like, while ensuring the positioning effect of the two electrical connection wires at the positioning groove 13 and preventing the two electrical connection wires from sliding at the positioning groove 13.

[0051] In one implementation, see Figure 4 and Figure 8 The connecting hole 12 is a tapered hole, and the diameter of the connecting hole 12 gradually increases as it moves away from the positioning groove 13. In this way, the connecting hole 12 is set to be tapered, and the diameter of the connecting hole 12 increases as the connecting hole 12 moves away from the positioning groove 13, thereby facilitating the electrical connection line to pass through the large end of the tapered structure of the connecting hole 15 until it passes through the small end of the tapered hole and extends to the position of the positioning groove 13.

[0052] In one implementation, see Figure 3 The connectors 11 are arranged parallel to each other, with the connecting portions 14 perpendicular to the length of the connectors 11. There are at least two connecting portions 14, and they are arranged parallel to each other. Thus, the parallel arrangement of the connectors 11 facilitates the insertion of the electrical connection wires into the inner holes of the connectors 11 in one direction, thereby preventing the electrical connection wires from bending. The provision of multiple connecting portions 14 improves the stability of the fixing between the connectors 11, thereby increasing the strength of the entire three-phase line holder.

[0053] In one implementation, see Figure 3-4The three-phase wire seat also includes a sealing ring 18, which surrounds the outer periphery of the connection seat 11 and is provided between the connection portion 14 and the positioning groove 13. In this way, the provision of the sealing ring 18 facilitates circumferential sealing during the installation of the three-phase wire seat, thereby protecting the fixing point of the electrical connection wire.

[0054] Specifically, the connecting portion 14 can be a structure that connects three connecting seats 11 at the same time; the connecting portion 14 can also be a structure that only connects two adjacent connecting seats 11, so two connecting portions 14 are required to connect the three connecting seats 11, and the two connecting portions 14 can be on the same plane or arranged in parallel.

[0055] In the prior art structure of the connecting seat 11 arranged in a straight line, there is still a problem of overall sealing, which leads to a problem of poor sealing effect. The present application adopts a method of sealing each connecting seat 11 individually, thereby effectively improving the sealing effect.

[0056] In one implementation, see Figure 2 and Figure 5 Connecting portion 14 includes mounting ears 16 and mounting holes 17. Mounting ears 16 extend outward along the edge of connecting portion 14. Mounting holes 17 are defined on mounting ears 16, and at least two mounting holes 17 are provided. Thus, providing mounting ears 16 to define mounting holes 17 improves the structural strength at the locations of mounting holes 17.

[0057] A connection component, see Figure 6-7 , including a three-phase wire holder for a motor, and also including a long copper bar 21, a three-phase copper bar 22, a connector 24 and a three-phase copper bar seat 23. The long copper bar 21 passes through the connecting hole 12 and extends to the positioning groove 13; the three-phase copper bar 22 extends to the positioning groove 13 and forms a partial overlapping structure with the long copper bar 21; the connector 24 presses the overlapping area of the three-phase copper bar 22 and the long copper bar 21; the three-phase copper bar seat 23 is connected to one end of the three three-phase copper bar 22. In this way, the long copper bar 21 and the three-phase copper bar 22 are connected through the three-phase wire holder. Specifically, during the connection, the long copper bar 21 passes through the connecting hole 12 and extends to the positioning groove 13, the three-phase copper bar 22 extends to the positioning groove 13 and forms a partial overlapping structure with the long copper bar 21 in the positioning groove 13, and the overlapping three-phase copper bar 22 and the long copper bar 21 are connected by the connector 24 at the positioning groove 13, thereby achieving the effect of fixing the three-phase copper bar 22 and the long copper bar 21.

[0058] For details, see Figure 8-9 The connecting member 24 can be a bolt, and the positioning groove 13 is provided with a corresponding connecting hole 15 to install the connecting member 24. The connecting hole 15 can be a threaded hole. In actual connection, the long copper bus 21 is used to connect the motor, and the three-phase copper bus 22 is used to connect the controller.

[0059] See also Figure 9The connector 24 presses the three-phase copper bus 22 and the long copper bus 21 into the positioning groove 13 in turn, and the three-phase copper bus 22 and the long copper bus 21 are tightly connected through the threaded connection between the connector 24 and the positioning groove 13.
