DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] A signal line includes an end docking device 2 and a protective outer layer 4, wherein the side end of the protective outer layer 4 is fixedly connected to the protective device 3, and the side of the protective device 3 is fixedly clamped to the end docking device 2, the inner end surface of the protective outer layer 4 is fixedly provided with a tensile layer 5, and the inner end surface of the tensile layer 5 is fixedly provided with a connecting layer 6, a supporting layer 7 is provided inside the connecting layer 6, and a signal line core 1 is provided at the center of the inner end surface of the supporting layer 7.

[0021] The end docking device 2 includes a docking socket 21, a positioning guide shaft 22 is arranged at the center of the inner end surface of the docking socket 21, and positioning slots 23 are equidistantly provided at the four corners of the front end surface of the docking socket 21, two groups of guide slides 25 are slidably engaged inside the side end surface of the docking socket 21, and three groups of limit plugs 24 are equidistantly arranged on the inner end surface of the guide slide 25, and spring retaining rings 26 are arranged at the four corners of the outer end surface of the guide slide 25.

[0022] The positioning guide rod 34 is adapted to the positioning slot 23, and the alignment plug 32 is adapted to the alignment guide shaft 22. The protective card cover 31 is slidably inserted into the docking card seat 21 through the adaptation of the positioning guide rod 34 to the positioning slot 23 and the adaptation of the alignment plug 32 to the alignment guide shaft 22. The double positioning and alignment structure can effectively improve the stability of the alignment connection of the alignment plug 32.

[0023] The front part of the limiting plug plate 24 is arranged in an arc shape, and the guide slide plate 25 is fixedly connected with the alignment slot 33 through the limiting plug plate 24.

[0024] Working principle: When performing protective positioning docking on the signal line, the user can hold the protective outer layer 4, and then align the alignment plug 32 and plug it into the docking card seat 21. When plugging, the four groups of positioning guide rods 34 can be first aligned to the inside of the positioning slot 23, and then the alignment guide shaft 22 can perform secondary positioning and guiding on the alignment plug 32, so that the alignment plug 32 can be accurately plugged into the inside of the docking card seat 21. When the alignment plug 32 is inserted into the inside of the docking card seat 21, the alignment plug 32 can push out the limit plug plate 24. Since the limit plug plate 24 is arranged in an arc shape toward the alignment plug 32, when the alignment plug 32 is fully plugged into the inside of the docking card seat 21, the three groups of limit plug plates 24 can be directly inserted into the alignment card slot 33 under the elastic support of the spring retaining ring 26, thereby completing the limiting operation of the alignment plug 32.
