[0011] Further, a plurality of terminal posts are linearly arranged at equal intervals on the terminal strip, and a separation rib is arranged between each adjacent two terminal posts.

[0012] Further, a plurality of exhaust ports are linearly arranged at equal intervals on the terminal strip.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] The protective shell, the buckle, the front panel, the terminal strip, the terminal post, the separation rib and the exhaust port are arranged, so that the protective shell can be directly embedded in the cabinet during installation, and the installation conditions of different use environments can be adapted. Since the terminal strip is arranged towards the rear panel of the cabinet, only the rear panel of the cabinet can be opened during maintenance, and the internal connecting wires are not disconnected, so that the operation amount of personnel is reduced, the maintenance efficiency is improved, the operation is very convenient, and the utility model has certain practical value.

[0015] The utility model will be explained in detail in combination with the drawings and specific embodiments. DRAWINGS
