In one possible embodiment, to fix and stabilize the static clip 210 along the second direction, both sides of the wire clamping portion 213 along the third direction are abutted against the first limiting protrusion 1131 on the corresponding side. Further, first blade 2121 is disposed on a side of first rivet body 2122 facing away from stepped side 112 such that first blade 2121 and inner wire 400 are free of compression 224.

In the present embodiment, referring to fig. 13 and 14, compared with the first embodiment, the housing 100 is identical in that the housing 100 also includes a bottom case 110 and a cover plate 120, and the cover plate 120 is provided with a second limiting protrusion 121 and a third positioning protrusion 122; the difference is that the cover plate 120 is further provided with the third spacing protrusions 124 corresponding to the wiring grooves 1111 one by one on one side towards the bottom shell 110, the third spacing protrusions 124 are located in the same plane with the first spacing protrusions 1131 extending along the first direction, the third spacing protrusions 124 extend to the pressing parts 224 along the third direction, edges of the pressing parts 224 on the side opposite to the step end face 111 along the second direction are abutted against the third spacing protrusions 124, and it can be understood that the first spacing protrusions 1131 extending along the first direction and the third spacing protrusions 124 simultaneously form spacing for the pressing parts 224, so that the movement of the pressing parts 224 along with the slide bar parts 225 is further stabilized.

The other structures of the wiring structure 1 provided in this embodiment are the same as those of the first embodiment, and will not be described in detail herein.

It is to be understood that the above examples of the present application are provided for clarity of illustration only and are not limiting of the embodiments of the present application. Various obvious changes, rearrangements and substitutions can be made by those skilled in the art without departing from the scope of the application. It is not necessary here nor is it exhaustive of all embodiments.
