[0037] Embodiment 1

[0038] See also Figure 1-Figure 7 As shown, in this embodiment, a multi-level cable harness structure for new energy vehicle communication is provided, including:

[0039] The lower shell 1 has a fixed seat 3 fixed on its inner wall, and a plurality of connecting channels 10 distributed in an annular shape are provided inside the fixed seat 3 for connecting the cable cores to ensure the transmission of signals. Connecting posts 12 and a plurality of arc blocks 11 distributed in an annular shape are fixed on both sides of the fixed seat 3. The plurality of arc blocks 11 are respectively arranged on one side of the connecting channel 10. The outer walls of the two connecting posts 12 are rotatably connected with movable rings 13. The outer wall of the movable ring 13 is fixed with a plurality of evenly distributed pressing blocks 14. The pressing blocks 14 and the arc blocks 11 are matched to press the cable cores to fix the cores, thereby ensuring the stability of the core connection and avoiding the separation of the cores. The same adjusting ring 15 is fixed at one end of the plurality of pressing blocks 14 to facilitate people to adjust the pressing blocks 14.

[0040] It also includes an upper shell 2, which is arranged at the top of the lower shell 1. The lower shell 1 and the upper shell 2 are combined into a tubular shape. The outer walls of both sides of the lower shell 1 and the upper shell 2 are provided with first threads 4 and are threadedly connected with connecting sleeves 5 through the first threads 4. One end of the two connecting sleeves 5 is provided with a mounting groove 6. The two mounting grooves 6 are provided with semi-ring blocks 7. The semi-ring blocks 7 cooperate with the connecting sleeves 5 to fix the cables. The stability of the cable connection is improved by double fixation. The outer walls of the connecting sleeve 5 and the semi-ring blocks 7 are provided with second threads 8 and are threadedly connected with mounting rings 9 through the second threads 8. The mounting rings 9 can limit the semi-ring blocks 7, thereby achieving the effect of fixing the cables.

[0041] Two limiting mechanisms are symmetrically arranged on both sides of the fixed seat 3, and are used to limit the adjusting ring 15. The limiting mechanisms include multiple limiting grooves 16 and slide grooves 22.

A limiting block 25 is fixed at one end of the slider 23, and one end of the limiting block 25 is located in one of the limiting grooves 16. The limiting block 25 cooperates with the limiting groove 16 to limit the adjusting ring 15, thereby ensuring the fixing effect of the pressing block 14 on the wire core.

[0042] Embodiment 2

[0043] Improved on the basis of embodiment 1: Refer to attached Figure 1-Figure 7 The inner wall of the semi-ring block 7 and the inner wall of the connecting sleeve 5 are both bonded with semi-sealing rings 18. The two semi-sealing rings 18 are combined into a tubular shape and embrace the outer wall of the cable, which can seal the connection between the semi-ring block 7 and the connecting sleeve 5, thereby improving the sealing of the structure.

[0044] In the present invention, two strip grooves 29 are provided at the bottom end of the upper shell 2, and sealing strips 30 are provided in the two strip grooves 29. The sealing strips 30 are in contact with the lower shell 1, and the connection between the lower shell 1 and the upper shell 2 can be sealed, thereby further improving the sealing performance of the structure.

[0045] In particular, two symmetrically arranged second positioning blocks 19 are fixedly provided at the bottom of the semi-ring block 7, and two second positioning grooves 20 are provided at the bottom of the mounting groove 6. The second positioning blocks 19 and the second positioning grooves 20 cooperate with each other to position the semi-ring block 7, thereby improving the stability of the structure.

[0046] It should be noted that the inner wall of the upper shell 2 is fixed with multiple first positioning blocks 28, and the outer wall of the fixing seat 3 is provided with multiple first positioning grooves 17. The first positioning blocks 28 and the first positioning grooves 17 cooperate with each other to position the upper shell 2, thereby improving the stability of the structure.

[0047] In the present invention, the connecting channel 10 includes a first connecting groove 26 and a second connecting groove 27, and the first connecting groove 26 and the second connecting groove 27 are respectively arranged on both sides of the fixing seat 3, and the first connecting groove 26 and the second connecting groove 27 are connected. The first connecting groove 26 is arc-shaped, and the first connecting groove 26 can guide one end of the wire core to bend slightly, so that it can be convenient to fully contact with another wire core.

[0048] In particular, a semi-limiting ring 21 is fixedly provided on the outer wall of the connecting sleeve 5 , which can limit the installation ring 9 and prevent the installation ring 9 from being separated from the connecting sleeve 5 .

[0049] The use process and working principle of the technical solution of the present invention are as follows:

[0050] When connecting two cables, first use a tool to cut and peel one end of the two cables, then put the two connecting sleeves 5 on the two cables respectively, then separate the cores of the cables and insert them into the first connecting groove 26, then rotate the adjusting ring 15, the adjusting ring 15 drives the pressing block 14 to rotate, the pressing block 14 cooperates with the arc block 11 to press the core, and then push the slider 23 to make the limit block 25 and the corresponding limit groove 16 dock, and similarly insert the core of the other cable into the second connecting groove 27 to dock the cores, and then rotate the adjusting ring 15 so that the pressing block 14 cooperates with the arc block 11 to The wire core is compressed, and then the upper shell 2 is pressed onto the fixed seat 3. With the cooperation of the first positioning block 28 and the first positioning groove 17, the upper shell 2 and the lower shell 1 are docked. Then the connecting sleeve 5 is threadedly connected to the two ends of the lower shell 1 and the upper shell 2. Then the half ring block 7 is placed in the installation groove 6. With the cooperation of the second positioning block 19 and the second positioning groove 20, the half ring block 7 and the connecting sleeve 5 are docked. Then the installation ring 9 is rotated to limit the half ring block 7. The half ring block 7 cooperates with the connecting sleeve 5 to compress the cable. In this way, the cable connection can be completed. When disassembling, repeat the above operation in reverse.
