[0029] Embodiments of the present invention are described in detail below, with examples of the embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following is for reference. Figures 1 to 7 The present invention describes a wiring assembly 200, a junction box 100 having the wiring assembly 200, and a motor.

[0031] like Figure 3 and Figure 4As shown, the wiring assembly 200 of this embodiment of the invention includes an insulating base 1 and a conductive sheet 2; the insulating base 1 includes an insulating base body 11 and an insulating block 12 disposed on the insulating base body 11, the insulating base body 11 and the insulating block 12 are detachably connected; the conductive sheet 2 is connected to each of the insulating base body 11 and the insulating block 12.

[0032] According to an embodiment of the present invention, the wiring assembly 200 detachably connects the insulating base body 11 and the insulating block 12, allowing the conductive sheet 2 and the insulating block 12 to be prefabricated during installation, thus improving the efficiency of on-site wiring assembly operations. Furthermore, if either the insulating base body 11 or the insulating block 12 malfunctions, only the faulty part needs to be replaced, reducing replacement costs and improving replacement efficiency.

[0033] Therefore, the wiring assembly 200 of the present invention has the advantages of improving on-site installation efficiency and fault replacement efficiency, and reducing replacement costs.

[0034] For ease of description, the following will be Figure 2 The vertical direction is used as the height direction of the wiring assembly 200, so as to Figure 2 For example, Figure 2 The left and right directions in the middle are used as the length direction of the wiring assembly 200. Figure 4 The front-to-back direction is used as the width direction of the wiring assembly 200.

[0035] like Figure 3 and Figure 4 As shown, the conductive sheet 2 includes a connected high-voltage connection segment 21 and a connecting segment 22. The high-voltage connection segment 21 and the connecting segment 22 form a predetermined angle, meaning the high-voltage connection segment 21 extends and bends along the direction forming this predetermined angle with the connecting segment 22. In other words, the high-voltage connection segment 21 can constitute the first bent portion 25 of the conductive sheet 2. The high-voltage connection segment 21 is connected to the insulating base body 11, and the connecting segment 22 is connected to the insulating block 12. Figure 4 As shown, the high-voltage connection section 21 is disposed on the upper surface of the insulating base body 11, and the connection section 22 extends in the vertical direction and is connected to the insulating block 12.

[0036] According to an embodiment of the present invention, the wiring assembly 200 forms a preset angle 24 by bending the high-voltage wiring section 21 and the connecting section 22. This allows for increased space for installing the motor high-voltage input wire and the motor lead 3 while keeping the height of the conductive sheet 2 and the height of the insulating base body 11 unchanged.

[0037] Optionally, the preset included angle is 90°. In other words, the conductive sheet 2 includes a high-voltage connection segment 21 and a connecting segment 22 extending in a direction perpendicular to the high-voltage connection segment 21, with the connection between the motor connection segment 23 and the connecting segment 22 forming a first bend 25. For example, the high-voltage connection segment 21 is horizontally arranged on the upper surface of the insulating base body 11, and the connecting segment 22 is arranged in the vertical direction. This further reduces the height of the conductive sheet 2 and the height of the insulating base body 11, improving the rationality of the structure.

[0038] Optionally, the angle 24 between the high-voltage connection section 21 and the connection section 22 can be adaptively adjusted according to the specific positions of the insulating block 12 and the insulating base body 11.

[0039] like Figure 3 and Figure 4 As shown, the high-voltage connection section 21 is located on the upper surface of the insulating base body 11, and the connection section 22 penetrates the insulating block 12.

[0040] The wiring assembly 200 according to an embodiment of the present invention improves the stability of installation and fixation by having the connecting segment 22 pass through the insulating block 12.

[0041] like Figure 3 and Figure 4 As shown, the insulating block 12 is injection molded onto the connecting section 22. In this embodiment of the invention, the wiring assembly 200 uses the insulating block 12 injection molded onto the connecting section 22, reducing installation steps and improving installation efficiency. It also improves the stability of the connection between the conductive sheet 2 and the insulating block 12. Therefore, the assembly efficiency and stability of the wiring assembly 200 are further improved.

[0042] like Figure 7 As shown, the connecting segment 22 is provided with one of a limiting groove 221 and a limiting protrusion, and the insulating block 12 is provided with the other of a limiting groove 221 and a limiting protrusion. The limiting protrusion fits within the limiting groove 221. Optionally, the connecting segment 22 is provided with a limiting groove 221, and the insulating block 12 is provided with a limiting protrusion; or, the connecting segment 22 is provided with a limiting protrusion, and the insulating block 12 is located within the limiting groove 221, with the limiting protrusion fitting within the limiting groove 221. This further improves the stability of the connection of the wiring assembly 200 in the height direction.

[0043] like Figure 7 As shown, the conductive sheet 2 also includes a motor wiring section 23. The motor wiring section 23, the connecting section 22 and the high-voltage wiring section 21 are an integral structure connected in sequence. The connection between the connecting section 22 and the high-voltage wiring section 21 forms a second bend 26.

[0044] Optionally, the conductive sheet 2, formed by the high-voltage terminal section 21, the connecting section 22, and the motor terminal section 23, is Z-shaped or "U"-shaped. The motor terminal section 23 increases the fixed area when connected to the motor lead 3, thereby improving stability. For example, when the motor terminal section 23 and the motor lead 3 are connected by welding, both the motor terminal section 23 and the motor lead 3 extend along the width direction of the wiring assembly 200, increasing the welding area between the motor lead 3 and the motor terminal section 23, thereby improving the stability of the connection between the motor lead 3 and the conductive sheet 2.

[0045] like Figures 2 to 5 As shown, there are three conductive plates 2, and the motor wiring segments 23 of the three conductive plates 2 are arranged on the same arc. Furthermore, the center of the arc on which the three conductive plates 2 are located is the same as the center of the motor stator winding that it matches, thereby improving the compactness of the wiring assembly 200.

[0046] Specifically, three conductive plates 2 are installed on the insulating base 1 in a coordinated manner. The three conductive plates 2 are spaced apart in the left-right direction, and the three conductive plates 2 are electrically connected to the three motor leads 3 of the motor in a one-to-one correspondence.

[0047] In other embodiments, the number of conductive sheets 2 can be set according to the connection requirements. For example, two conductive sheets 2 can be provided, and the two conductive sheets 2 are electrically connected to the two motor leads 3 of the motor in a one-to-one correspondence.

[0048] like Figures 2 to 5 As shown, the insulating base body 11 includes a mounting part 111 and a first support part 1121 (located in...). Figure 4 (left side of the middle) and the second support part 1122 (located in the middle left) Figure 4 (Right side of the middle). The mounting part 111 has a preset direction (e.g., Figure 2 The mounting part 111 has a first end 1111 and a second end 1112 facing each other in the left-right direction. The mounting part 111 is connected to the high-voltage connection section 21. A first support part 1121 is provided on the first end 1111 of the mounting part 111, and a second support part 1122 is provided on the second end 1112 of the mounting part 111. A first slot 1123 is provided on the first support part 1121, and a second slot 1124 is provided on the second support part 1122. The first slot 1123 and the second slot 1124 are arranged opposite each other. The insulating block 12 has a first end 121 and a second end 122 facing each other in a preset direction. The first end 121 of the insulating block 12 is embedded in the first slot 1123, and the second end 122 of the insulating block 12 is embedded in the second slot 1124. During on-site installation, the prefabricated mounting parts made of the insulating block 12 and the conductive sheet 2 are connected to the insulating base body 11, which further simplifies the on-site installation steps.

[0049] Optionally, the mounting part 111 is provided with two limiting plates 113. The limiting plates 113 are arranged in the front-back direction and divide the mounting part 111 into three mounting positions 13. Each high-voltage wiring segment 21 is provided on the mounting position 13. Each of the mounting part 111 and the high-voltage wiring segment 21 is provided with a mounting hole 14 extending in the height direction of the insulating base 1. The mounting hole 14 is provided with a connecting screw 15 for connecting the conductive sheet 2 and the insulating base body 11.

[0050] Optionally, the projection of the first card slot 1123 and the second card slot 1124 in the horizontal direction is C-shaped, T-shaped or rectangular.
