Industrial Ethernet switch with protection function

The utility model belongs to the technical field of Ethernet switches, and particularly relates to an industrial Ethernet switch with a protection function, which comprises a switch body, at least two arc-shaped protection edge strips are arranged outside the switch body, two ends of each arc-shaped protection edge strip are folded towards the lower part of the side edge of the switch body to form an inner buckling rod, and the inner buckling rod is connected with the switch body. A connecting plate is arranged at one end, positioned towards the lower side of the switch body, of the inner buckling rod, and the connecting plate is connected with the lower surface of the switch body through a screw; and the elastic supporting piece is connected between the side wall of the switch body and the side edge of the arc-shaped protection edge strip. The periphery of the switch body is supported and protected through the multiple arc-shaped protection edge strips, ventilation and heat dissipation are not affected due t
