[0027] like Figure 1-Figure 2 As shown, in this embodiment, the protective structure 2 includes a first structure 21 and a second structure 22, which are used to fix and protect the cable 1. The return line 121 passes through the first structure 21 and the second structure 22 and is led forward to the waterproof plug of the switch, while the grounding line 122 passes through the first structure 21 and the second structure 22 and is led upward to the ground.

[0028] Furthermore, the first structural member 21 is symmetrically arranged and surrounds and covers the stripping fork 11 of the cable 1. The first structural member 21 has a covering cavity 211 and a lead-out cavity 212. The covering cavity 211 is used to accommodate the cable 1, and the lead-out cavity 212 is used to lead out the return line 121 and the ground line 122 in the branch 12 respectively.
