[0027] The top of the box 4 is provided with a horizontal support plate 6, and the support plate 6 is provided with multiple cable trays 61 for optical fiber routing.

[0028] This utility model is installed on the outer wall of the shelter 100. The adapter 1 is divided into two areas: an optical signal adapter area 11 and an electrical signal adapter area 12. Electrical signal transmission: The cables inside the shelter are connected to the cable adapter socket 122, and the cables outside the shelter are connected to the external connector socket 5, realizing the electrical signal conversion between the inside and outside of the shelter. Because the housing 4 is equipped with a filter 42, no noise is generated during electrical signal transmission, improving the accuracy of the receiving equipment in judging electrical signals. Optical signal transmission: The optical fiber cable outside the shelter is directly connected to the optical fiber cable inside the shelter through the optical fiber adapter socket 111 and the cable tray 61. The optical fiber adapter socket 111 is also connected to a coupler. This achieves the connection of photoelectric signals between the inside and outside of the shelter, improving anti-interference capability.

[0031] Specifically, the cable tie fixing base 2 is provided with multiple cable brackets 21, and each cable bracket 21 has multiple cable binding holes 211.

[0032] Through the above design, this utility model uses cable ties to fix the cable and fiber optic cable to the cable bracket 21, preventing the cable from getting tangled and pulling the external connector seat 5 off.

[0033] Specifically, both the adapter 1 and the wire fixing seat 2 are provided with outwardly extending edges, and buckles 7 are provided on the edges. The bottom of the protective cover 3 is provided with a lock 71 corresponding to the buckles 7.
