Among them: the power transmission line 2 includes a positive transmission line 21 and a negative transmission line 22. In this cable structure, the sheath 1 is located at the outermost position of the cable structure; the ground line 3 and the multiple signal lines 4 are arranged in the middle position of the cable structure, and the ground line 3 is located at the center point, that is, the ground line 3 is located at the center of the cable; the power transmission line 2 is arranged on the outside around the multiple signal lines 4 and the ground line 3, close to the sheath 1.

[0044] refer to Figure 1 As shown in FIG. 1 , in this embodiment, the positive transmission line 21 and the negative transmission line 22 are both nearly crescent-shaped conductor structures, and the two are arranged in an embracing shape.

[0045] Among them, the positive transmission line 21 and the negative transmission line 22 are interconnected at the head and tail ends through an insulator, that is, an insulator is arranged between the head and tail ends of the positive transmission line 21 and the negative transmission line 22 close to the interconnection, so that the positive transmission line 21 and the negative transmission line 22 are only connected at the head and tail ends but not conductive, forming a closed first space o1, and the multiple signal lines 4 and the ground line 3 are arranged in the first space o1.

[0046] In this embodiment, the ground wire 3 uses a standard cable and is located at the center point; the multiple signal wires 4 are located in the first space on the upper and lower sides of the ground wire 1, close to the sheath 1. However, the present invention is not limited to this, and all the multiple signal wires 4 can also be arranged in the space on one side of the ground wire 1. Different arrangements can be made according to the actual size of the first space and the number of the multiple signal wires 4, and are not limited to this.

[0047] In addition, in some embodiments, the charging gun cable structure is a DC charging gun cable, that is, the positive transmission line is a DC+ transmission line, and the negative transmission line is a DC- transmission line, but the present invention is not limited to a DC charging gun cable.

[0048] In addition, in some embodiments, the gaps between the positive transmission line 21 , the negative transmission line 22 , the ground line 3 , the plurality of signal lines 4 , and the sheath 1 are filled with polypropylene (PP) fillers 5 .

The power transmission line ensures current carrying, and the signal line meets the requirements for monitoring some real-time data during charging, and there is a path for transmitting the temperature detection signal to ensure that the charging process is safe and accurate. Compared with the existing cable structure, the outer diameter of the charging gun cable in this embodiment is thinner, the weight of the same length is lighter, the flexibility is better, the overall performance is better, and the service life is longer.
