The invention discloses a wire terminal protection cover. The wire terminal protection cover comprises a front shell and a rear shell. The front shell and the rear shell are connected through a connecting block. The other side of the front shell and the other side of the rear shell are provided with buckles and are connected through the buckles to form an annular cover body. The front shell, the connecting block and the rear shell are made from polycarbondined. A front shell partition board is arranged in the front shell. A rear shell partition board is arranged in the rear shell. The front shell partition board and the rear shell partition board are located at the same altitude, and through holes are evenly distributed in the front shell partition board and the rear shell partition board.The interior of the cover body is divided into an upper cavity and a lower cavity by the front shell partition board and the rear shell partition board. Buffer pads are evenly distributed on the inner wall of the upper cavity. A drying agent is placed in the lower cavity. According to the wire terminal protection cover, the cover body formed by connecting the front shell and the rear shell in a clamped mode is arranged, the interior of the cover body is divided into the two cavities by the partition boards provided with the through holes, the buffer pads are mounted on the inner wall of the upper cavity, the drying agent is placed in the lower cavity, and thus, wire terminals are protected.
