The invention discloses an electric distribution box of a 5G signal tower. The electric distribution box comprises a box body. A communicated inner cavity is formed in the box body. A plurality of cushion blocks are fixedly arranged on the lower end surface of the box body and are abutted against the ground. Rotating bases arranged in a vertical symmetric manner are arranged at the front end surface of the box body; and a rotating door is rotationally arranged between the rotating bases. Batch installation devices which are arranged in a left-right alternating mode are arranged in the inner cavity; and sliding fit devices arranged in the inner cavity are arranged at the outer sides of the batch installation devices. A turning plate device that is used for heat dissipation and is convenientto clean is arranged at the rear side of the box body. On the basis of designs of the batch installation devices, the sliding fit devices, and the turning plate device, 5G communication equipment canbe installed efficiently; the staff member can repair the equipment conveniently; and the use efficiency and reliability of the equipment are greatly improved.
