[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1:

[0041] like Figures 1 to 5 As shown, the present invention provides an electric vehicle controller connection harness, which mainly includes a wire 1, a rubber strip 2, a pressing block 3, a positioning seat 4 and a pressure plate 5. The positioning seat 4 is fixedly connected to a side surface of the controller housing 7. The positioning seat 4 is provided with a positioning hole 411, which communicates with the inside and outside of the controller housing 7 and is used to pass the wire 1.

[0042] Combine Figure 5 and Figure 6 As shown, multiple conductors 1 are arranged in parallel in a row. The rubber strip 2 is formed in the middle of the conductor 1 by casting, and the middle of the conductor 1 is completely covered in the rubber strip 2. The main purpose of the rubber strip 2 is to position each conductor 1 so that the spacing between adjacent conductors is roughly equal, which is convenient for subsequent connection with the pressing block 3. The two pressing blocks 3 are clamped in the middle of the conductor 1, and the two pressing blocks 3 are symmetrical up and down. Positioning grooves 32 are provided on the opposite surfaces of the two pressing blocks 3, and the rubber strip 2 is fitted in the positioning groove 32 to achieve preliminary positioning of each conductor 1; arc-shaped grooves 31 matching the conductor 1 are also provided on the opposite surfaces of the two pressing blocks 3, and the conductor 1 after preliminary positioning is matched and installed in the arc-shaped groove 31; after the upper and lower pressing blocks 3 are buckled together, the conductor 1 is clamped in the arc-shaped groove 31.

[0043] When in use, the two buckled pressing blocks 3 are embedded in the positioning holes 411 on the positioning seat 4, and the pressure plate 5 is used to press the outer end of the pressing block 3 to prevent the pressing block 3 from falling off; the pressing block 3 is made of rubber material, and the mutual extrusion and deformation of the upper and lower pressing blocks 3 ensures the sealing of the joint and improves the waterproof performance of the connecting harness.

[0044] Example 2:

[0045] Combine Figures 1 to 5As shown, based on the above-mentioned embodiment 1, in this embodiment, an elongated hole is provided on the controller housing 7 to cooperate with the positioning seat 4. The positioning seat 4 includes a cylinder 41, which is inserted into the elongated hole of the controller housing 7; the inner hole of the cylinder 41 is a positioning hole 411, which is used to embed the pressing block 3; the outer end of the cylinder 41 has a flange 42, which is connected to the controller housing 7, and a sealing gasket 43 is provided between the flange 42 and the controller housing 7 to ensure the sealing between the positioning seat 4 and the controller housing 7. The inner wall of the cylinder 41 has a certain taper, and the outer peripheral surface of the two pressing blocks 3 also has a certain taper; the outer peripheral surface of the two pressing blocks 3 and the inner wall of the positioning hole 411 adopt this wedge-shaped matching form, so that when the two pressing blocks 3 are squeezed inward, the two pressing blocks 3 will gradually approach each other, and the joint surface will be pressed tighter and tighter.

[0046] The pressure plate 5 is connected to the flange 42 and has an elongated hole in its center for the wire 1 to pass through. A circle of bosses 51 are located on the sides of the pressure plate 5, pressing against the outer ends of the two compression blocks 3. During use, tightening the pressure plate 5 gradually pushes the two compression blocks 3 inward, gradually tightening them and ensuring a tight seal between the two compression blocks 3 and the wire 1.

[0047] Example 3:

[0048] Combine Figures 1 to 5 As shown, based on the above embodiment 2, in this embodiment, the controller housing 7, the flange 42 and the pressure plate 5 are fixed as one through the connecting piece 6;

[0049] Opposite light holes are provided between the controller housing 7, the flange 42 and the pressing plate 5. The diameter of the light hole on the controller housing 7 is smaller than that of the light hole on the pressing plate 5. The light hole on the flange 42 is a stepped hole.

[0050] Connector 6 is a stepped cylindrical structure with a large end and a small end. Both ends of connector 6 are provided with threaded blind holes, which are not interconnected. The step of connector 6 fits into the aperture of flange 42. A groove is provided at the step location, in which a sealing ring 63 is installed. The sealing ring 63 is squeezed into the aperture of flange 42, achieving a seal between connector 6 and flange 42. The small-diameter end of connector 6 is inserted into the aperture of flange 42 and controller housing 7. An inner bolt 6 is connected to the small-diameter end of connector 6, which presses against the inner side of controller housing 7 to secure flange 42. An inner bolt 61 is installed to tighten controller housing 7. The large-diameter end of connector 6 is inserted into the aperture of flange 42 and pressure plate 5. An outer bolt 62 is connected to the large-diameter end of connector 6, which presses against pressure plate 5 to secure pressure plate 5.

[0051] Usage process:

[0052] Combine Figures 1 to 6 As shown, the sealing ring 63 is mounted on the cylinder 41, and the cylinder 41 is inserted into the controller housing 7. The small diameter end of the connector 6 is passed through the light holes of the flange 42 and the controller housing 7, and the inner bolt 6 is connected to the small diameter end of the connector 6 to realize the installation of the positioning seat 4.

[0053] Buckle the upper and lower pressing blocks 3 onto the rubber strip 2 and the wire 1. The rubber strip 2 is fitted into the positioning groove 32, and the wire 1 is clamped in the arc-shaped groove 31. Then push the buckled pressing blocks 3 into the positioning holes 411 on the positioning seat 4.

[0054] The light hole of the pressure plate 5 is penetrated at the large diameter end of the connecting part 6, the external bolt 62 is connected to the large diameter end of the connecting part 6 and the external bolt 62 is gradually tightened, the pressure plate 5 is pressed toward the pressing block 3, and the two pressing blocks 3 are gradually pushed into the positioning hole 411, and the two pressing blocks 3 are gradually pressed.
