[0032] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0033] like Figures 1 to 10As shown, this embodiment provides a high-voltage cable, including: a cable structure 1 and a connector 2. The cable structure 1 includes a first cable 11 and a second cable 12. The connector 2 is located between the first cable 11 and the second cable 12. One end of the connector 2 is screwed to the first cable 11, and the other end of the connector 2 is screwed to the second cable 12.

[0034] In this embodiment, one end of the connector 2 is screwed to the first cable 11, and the other end of the connector 2 is screwed to the second cable 12, thereby connecting the first cable 11 and the second cable 12. Connecting the first cable 11 and the second cable 12 by screwing the connector 2 not only simplifies the assembly process of the high-voltage cable and improves assembly efficiency, but also enhances the stability of the high-voltage cable assembly, preventing loosening of the connection due to vibration or thermal expansion and contraction.

[0035] Combination Figure 2 As shown, the high-voltage cable also includes a first crimp terminal 3 and a second crimp terminal 4. One end of the connector 2 is screwed to the first cable 11 through the first crimp terminal 3, and the other end of the connector 2 is screwed to the second cable 12 through the second crimp terminal 4.

[0036] In this embodiment, the first crimp terminal 3 and the second crimp terminal 4 are made of copper and have electrical conductivity.

[0037] In this embodiment, the first crimp terminal 3 is screwed to the connector 2 and connected to the first cable 11. The screwing connection between the connector 2 and the first cable 11 via the first crimp terminal 3 not only ensures stable current transmission but also improves the reliability of the electrical connection. The second crimp terminal 4 is screwed to the connector 2 and connected to the second cable 12. The screwing connection between the connector 2 and the second cable 12 via the second crimp terminal 4 not only ensures stable current transmission but also improves the reliability of the electrical connection.

[0038] It should be understood that the first crimp terminal 3 is first connected to the first cable 11 as a whole, and then the first crimp terminal 3 is screwed to the connector 2. The second crimp terminal 4 is first connected to the second cable 12 as a whole, and then the second crimp terminal 4 is screwed to the connector 2.

[0039] In other embodiments, one end of connector 2 is directly screwed to the first cable 11, and the other end of connector 2 is directly screwed to the second cable 12.

[0040] Combination Figure 2 As shown, the first crimp terminal 3 has a first groove 101 along the length x of the first cable 11, and the opening of the first groove 101 faces the second cable 12. The second crimp terminal 4 has a second groove 102 along the length x of the second cable 12, and the opening of the second groove 102 faces the first cable 11.

[0041] It should be understood that the length direction x of the first cable 11 is parallel to the length direction x of the second cable 12.

[0042] Combination Figure 2 As shown, the connector 2 includes a first conductive part 211 and a second conductive part 212. The first conductive part 211 is connected to the second conductive part 212. The first conductive part 211 is located in the first groove 101 and is screwed to the groove wall of the first groove 101. The second conductive part 212 is located in the second groove 102 and is screwed to the groove wall of the second groove 102.

[0043] In this embodiment, by providing a first groove 101 in the first crimp terminal 3, the first groove 101 can provide a precise screwing space for the first conductive part 211, avoiding misalignment between the screwing of the first conductive part 211 and the first crimp terminal 3; by providing a second groove 102 in the second crimp terminal 4, the second groove 102 can provide a precise screwing space for the second conductive part 212, avoiding misalignment between the screwing of the second conductive part 212 and the second crimp terminal 4.

[0044] In this embodiment, the first conductive part 211 is disposed within the first groove 101 and screwed to the groove wall of the first groove 101. This increases the screwing area between the first conductive part 211 and the first groove 101, which not only increases the stability of the connection between the first conductive part 211 and the first crimp terminal 3, but also increases the conductive area to accommodate high current transmission. Similarly, the second conductive part 212 is disposed within the second groove 102 and screwed to the groove wall of the second groove 102. This increases the screwing area between the second conductive part 212 and the second groove 102, which not only increases the stability of the connection between the second conductive part 212 and the second crimp terminal 4, but also increases the conductive area to accommodate high current transmission.

[0045] Combination Figure 2 , Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the groove wall of the first groove 101 is provided with a first internal thread a, and the outer peripheral side of the first conductive part 211 is provided with a first external thread b, and the first internal thread a matches the first external thread b.

[0046] In this embodiment, the first internal thread a of the first groove 101 matches the first external thread b of the first conductive part 211, that is, the thread direction of the first internal thread a is opposite to the thread direction of the first external thread b, so as to realize the screw connection between the first conductive part 211 and the first crimp terminal 3.

[0047] In this embodiment, the first external thread b of the first conductive part 211 is a left-hand thread, and the first internal thread a of the first groove 101 is a right-hand thread.

[0048] In other embodiments, the first external thread b of the first conductive portion 211 is a right-hand thread, and the first internal thread a of the first groove 101 is a left-hand thread.

[0049] It should be understood that since the first conductive part 211 is provided with a first external thread b, the first conductive part 211 can be equivalent to a stud; at the same time, since the groove wall of the first groove 101 is provided with a first internal thread a, the first crimp terminal 3 can be equivalent to a nut, thereby realizing the screw connection between the first conductive part 211 and the first crimp terminal 3.

[0050] Combination Figure 2 , Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the groove wall of the second groove 102 is provided with a second internal thread c, and the outer peripheral side of the second conductive part 212 is provided with a second external thread d, and the second internal thread c matches the second external thread d.

[0051] In this embodiment, the second internal thread c of the second groove 102 matches the second external thread d of the second conductive part 212, that is, the thread direction of the second internal thread c is opposite to the thread direction of the second external thread d, so as to realize the screw connection between the second conductive part 212 and the second crimp terminal 4.

[0052] In this embodiment, the second external thread d of the second conductive part 212 is a right-hand thread, and the second internal thread c of the second groove 102 is a left-hand thread.

[0053] In other embodiments, the second external thread d of the second conductive part 212 is a left-hand thread, and the second internal thread c of the second groove 102 is a right-hand thread.

[0054] It should be understood that since the second conductive part 212 is provided with a second external thread d, the second conductive part 212 can be equivalent to a stud; at the same time, since the groove wall of the second groove 102 is provided with a second internal thread c, the second cable 12 can be equivalent to a nut, thereby realizing the screw connection between the second conductive part 212 and the second crimp terminal 4.

[0055] In this embodiment, the thread direction of the first external thread b of the first conductive part 211 is opposite to the thread direction of the second external thread d of the second conductive part 212. Since the first external thread b of the first conductive part 211 is a left-hand thread and the second external thread d of the second conductive part 212 is a right-hand thread, when the first conductive part 211 and the second conductive part 212 rotate clockwise synchronously, the first conductive part 211 can be screwed to the first crimp terminal 3, and the second conductive part 212 can also be screwed to the second crimp terminal 4, thereby realizing the synchronous screwing of the first conductive part 211 to the first crimp terminal 3 and the second conductive part 212 to the second crimp terminal 4.

[0056] Furthermore, when the first conductive part 211 and the second conductive part 212 rotate counterclockwise synchronously, the first conductive part 211 can be separated from the first crimp terminal 3, and the second conductive part 212 can also be separated from the second crimp terminal 4, thereby realizing the synchronous separation of the first conductive part 211 from the first crimp terminal 3 and the second conductive part 212 from the second crimp terminal 4.

[0057] Combination Figure 4 and Figure 5 As shown, the connector 2 also includes an intermediate conductive part 213, one end of which is connected to the first conductive part 211, and the other end of which is connected to the second conductive part 212.

[0058] In this embodiment, the intermediate conductive part 213 is connected between the first conductive part 211 and the second conductive part 212. By rotating the intermediate conductive part 213, the first conductive part 211 and the second conductive part 212 are driven to rotate synchronously, so that the first conductive part 211 can be screwed or decoupled from the first crimp terminal 3, and the second conductive part 212 can be screwed or decoupled from the second crimp terminal 4.

[0059] Combination Figure 5 As shown, the outer diameter of the intermediate conductive part 213 is larger than the outer diameter of the first conductive part 211; the outer diameter of the intermediate conductive part 213 is larger than the outer diameter of the second conductive part 212.

[0060] In this embodiment, when the first conductive part 211 is screwed to the first crimp terminal 3, the first crimp terminal 3 abuts against the intermediate conductive part 213. The intermediate conductive part 213 can limit the screwing position of the first crimp terminal 3 and the first conductive part 211, preventing misalignment of the first crimp terminal 3 from affecting the screwing connection between the second crimp terminal 4 and the second conductive part 212. When the second conductive part 212 is screwed to the second crimp terminal 4, the second crimp terminal 4 abuts against the intermediate conductive part 213. The intermediate conductive part 213 can limit the screwing position of the second crimp terminal 4 and the second conductive part 212, preventing misalignment of the second crimp terminal 4 from affecting the screwing connection between the first crimp terminal 3 and the first conductive part 211.

[0061] In this embodiment, the conductive part 21 includes a first conductive part 211, a second conductive part 212 and an intermediate conductive part 213, and the conductive part 21 is made of copper material.

[0062] It should be understood that pure copper (also known as red copper or pure copper) is pure copper with a copper content of ≥99.9%, and it is named for its purplish-red color after surface oxidation.

[0063] Combination Figure 2As shown, the connector 2 also includes an insulating part 22, which has a cavity 201; the first conductive part 211, the second conductive part 212 and the intermediate conductive part 213 are all located in the cavity 201, the intermediate conductive part 213 is connected to the insulating part 22, and the first conductive part 211 and the second conductive part 212 are spaced apart from the insulating part 22.

[0064] In this embodiment, the first conductive part 211, the second conductive part 212, and the intermediate conductive part 213 are all disposed inside the cavity 201 of the insulating part 22, so as to avoid the first conductive part 211, the second conductive part 212, and the intermediate conductive part 213 being directly exposed to the outside, thereby avoiding the problem of short circuit or leakage of high voltage cables, and ensuring the safety of the electrical system.

[0065] For example, the insulating part 22 can be made of materials such as cross-linked polyethylene, ethylene propylene rubber, and silicone rubber.

[0066] Combination Figures 3 to 5 As shown, the insulating part 22 includes a first insulating part 221, a second insulating part 222 and an intermediate insulating part 223. The intermediate insulating part 223 is connected between the first insulating part 221 and the second insulating part 222, and is connected to the intermediate conductive part 213. The intermediate insulating part 223 has a "regular hexagonal structure".

[0067] In this embodiment, the intermediate insulating portion 223 has a "regular hexagonal structure," meaning that the cross-section of the intermediate insulating portion 223 is a regular hexagon with all six sides of equal length, and the included angle between any two adjacent sides is 120°. The intermediate insulating portion 223 has a "regular hexagonal structure" to accommodate specialized tools such as wrenches.

[0068] In this embodiment, the intermediate insulating part 223 is turned by a special tool such as a wrench to drive the first conductive part 211, the second conductive part 212 and the intermediate conductive part 213 to rotate synchronously, thereby realizing the screw connection or separation of the first conductive part 211 and the first crimp terminal 3, and the screw connection or separation of the second conductive part 212 and the second crimp terminal 4.

[0069] It should be understood that, since screw connections are highly stable and disassembly requires the use of specialized tools such as wrenches, the screw connection between the first conductive part 211 and the first crimp terminal 3, and the screw connection between the second conductive part 212 and the second crimp terminal 4, do not require interlock detection by the controller to release controller resources.

[0070] In this embodiment, combined with Figure 2 and Figure 5As shown, the cavity 201 includes a first sub-cavity 201a and a second sub-cavity 201b. The first sub-cavity 201a and the second sub-cavity 201b are located on two opposite sides of the intermediate conductive part 213 along the length direction x of the first cable 11. The first sub-cavity 201a is located in the first insulating part 221, and the second sub-cavity 201b is located in the second insulating part 222. The first conductive part 211 is located in the first sub-cavity 201a, and the second conductive part 212 is located in the second sub-cavity 201b.

[0071] It should be understood that, since the first conductive part 211 is located within the first sub-cavity 201a, when the first crimp terminal 3 is screwed onto the first conductive part 211, the first cable 11 and the first crimp terminal 3 need to be placed inside the first sub-cavity 201a. Since the second conductive part 212 is located within the second sub-cavity 201b, when the second crimp terminal 4 is screwed onto the second conductive part 212, the second cable 12 and the second crimp terminal 4 need to be placed inside the second sub-cavity 201b.

[0072] Furthermore, the connector 2 also includes a first sealing member 23 and a second sealing member 24. The first sealing member 23 is located in the first sub-cavity 201a and connected to the first insulating part 221. The first sealing member 23 is disposed between the first cable 11 and the first insulating part 221. The second sealing member 24 is located in the second sub-cavity 201b and connected to the second insulating part 222. The second sealing member 24 is disposed between the second cable 12 and the second insulating part 222.

[0073] In this embodiment, both the first sealing element 23 and the second sealing element 24 are sealing rings. When the first crimp terminal 3 is screwed onto the first conductive part 211, both the first cable 11 and the first crimp terminal 3 are located within the first sub-cavity 201a. The first cable 11 passes through the first sealing element 23. At this time, the first sealing element 23 is located between the first cable 11 and the first insulating part 221, and the first sealing element 23 can seal the gap between the first cable 11 and the first insulating part 221 to achieve a waterproof and dustproof effect. When the second crimp terminal 4 is screwed onto the second conductive part 212, both the second cable 12 and the second crimp terminal 4 are located within the second sub-cavity 201b. The second cable 12 passes through the second sealing element 24. At this time, the second sealing element 24 is located between the second cable 12 and the second insulating part 222, and the second sealing element 24 can seal the gap between the second cable 12 and the second insulating part 222 to achieve a waterproof and dustproof effect.

[0074] In this embodiment, the manufacturing sequence of the connector 2 is as follows: the conductive part 21 is formed by machining the first conductive part 211, the second conductive part 212 and the intermediate conductive part 213; then, the conductive part 21 and the insulating part 22 are integrally injection molded; finally, the first sealing member 23 is ultrasonically welded to the first insulating part 221 and the second sealing member 24 is ultrasonically welded to the second insulating part 222.

[0075] In other embodiments, the first cable 11 and the second cable 12 may both be replaced with aluminum rods to achieve the transfer between aluminum rods; or, the first cable 11 and the second cable 12 may both be replaced with copper rods to achieve the transfer between copper rods.

[0076] In summary, when the first crimp terminal 3 and the second crimp terminal 4 are screwed to the connector 2, the first cable 11 and the first crimp terminal 3 are first placed into the first sub-cavity 201a, and the second cable 12 and the second crimp terminal 4 are placed into the second sub-cavity 201b; then, the intermediate insulating part 223 is turned by a wrench or other special tools, and the intermediate conductive part 213 connected to the intermediate insulating part 223 drives the first conductive part 211 and the second conductive part 212 to rotate, thereby realizing the screwing of the first conductive part 211 to the first crimp terminal 3 and the screwing of the second conductive part 212 to the second crimp terminal 4.
