For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0032] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0033] like Figure 1 and 2 As shown, in one embodiment of this utility model, the cable structure includes a protective outer body 1 and at least two wire harnesses 2; the protective outer body 1 is provided with at least two parallel mounting holes 11; two adjacent mounting holes 11 are not connected; each wire harness 2 is disposed inside the corresponding mounting hole 11; at least two channels 3 are provided around the outer surface of each mounting hole 11; and some of the channels 3 are disposed between two adjacent mounting holes 11.

[0034] The technical solution of this utility model can separate the wire harnesses in the two mounting holes by using a channel arranged around them, which can effectively reduce the relative permittivity of each position, ensure the stability of wire harness transmission and output signals, and thus reduce the attenuation loss of the cable at high frequencies, improving the safety and stability of use.

[0035] Specifically, in some implementations, such as Figure 1 As shown, the wire harness 2 includes a metal conductor 21 and an insulating sleeve 22 disposed on the outer circumference of the metal conductor 21; and the insulating sleeve 22 is connected to the inner wall of the mounting hole 11. The insulating sleeve 22 is made of FEP (Fluorinated ethylene propylene) or ceramicized silicone rubber. The metal conductor 21 is made of copper or copper with a silver-plated outer surface.

[0036] Specifically, in some implementations, such as Figure 1 As shown, the two adjacent channels 3 surrounding the mounting hole 11 are not connected; and the two channels 3 surrounding different mounting holes 11 are not connected. In other words, by using multiple sets of independent and through channels 3, the relative permittivity at each location can be reduced, ensuring the stability of the wire harness transmission and output signal, and thus reducing the attenuation loss of the cable at high frequencies.

[0037] Specifically, in some implementations, such as Figure 1 and 2 As shown, on each mounting hole 11, all channels 3 are symmetrically arranged along the central axis of the corresponding mounting hole 11; and on two adjacent mounting holes 11, all channels 3 surrounding different mounting holes 11 are symmetrically arranged. That is, all corresponding channels 3 are symmetrically arranged around the circumference of the mounting hole 11 to uniformly reduce the relative permittivity, ensuring the stability of the wire harness transmission and output signal. Simultaneously, by symmetrically arranging the channels 3 at the position of each mounting hole 11, the relative permittivity of each part can be effectively controlled to tend towards the same level, thereby ensuring that the frequency of the transmitted signal is relatively consistent and avoiding the influence of magnetic field interference between different signal frequencies; thus improving the safety and stability of use.

[0038] Specifically, in some embodiments, the relationship between the distance L1 between two adjacent channels 3 arranged around the mounting hole 11 and the distance L2 between two adjacent channels 3 on different mounting holes 11 satisfies: L1 = (1 / 3 to 1 / 2) * L2. That is, L1 = 1 / 3 * L2, L1 = 2.5 / 6 * L2, L1 = 2.8 / 6 * L2, L1 = 1 / 2 * L2, etc.; preferably, L1 = 1 / 2 * L2. This structure, through a suitable distance difference, can ensure that interference between different wire harnesses 2 is minimized, and can also ensure the compactness of the overall structure, which is beneficial for saving materials and space.

[0039] Specifically, in some implementations, such as Figure 1 and 3 As shown, the protective outer body 1 includes a protective inner layer 101 and a protective outer layer 102 disposed on the outer surface of the protective inner layer 101; and the channel 3 and the mounting hole 11 are both disposed inside the protective inner layer 101. This structure, through a split casting process, can improve the ease of processing and forming of the channel 3 and the mounting hole 11, thereby improving production efficiency. In some embodiments, the protective outer layer 102 is made of PE (polyethylene), TPE (thermoplastic elastomer), TPR (thermoplastic elastomer), or TPU (polyurethane), etc. The protective inner layer 101 is made of PE (polyethylene), TPE (thermoplastic elastomer), TPR (thermoplastic elastomer), or TPU (polyurethane), etc. The material of the protective outer layer 102 is the same as that of the protective inner layer 101.

[0040] Specifically, in some implementations, such as Figure 3 and 4As shown, the inner protective layer 101 includes at least two interconnected protective units, each of which includes an annular portion 103, a connecting portion 104, and a limiting arc portion 105. The mounting hole 11 is disposed inside the annular portion 103. The number of connecting portions 104 corresponds to the number of limiting arc portions 105. At least two connecting portions 104 are provided, and they are arranged around the outer surface of the annular portion 103 away from the mounting hole 11. The limiting arc portion 105 is connected to one end of the connecting portion 104 away from the annular portion 103. A channel 3 is formed between the annular portion 103, the connecting portion 104, and the limiting arc portion 105. An assembly gap 106 is provided between two adjacent limiting arc portions 105. The outer protective body 102 is filled and connected to the assembly gap 106. The inner wall of the outer protective body 102 is connected to the outer surface of the limiting arc portion 105 away from the connecting portion 104.
