Provided is a current transformer end shield wire clamp achieving secure clamping structure, shedding prevention, convenient installation, and an increase in operating efficiency. The current transformer end shield wire clamp comprises a pipe sleeve. Two radial oppositely-arranged shaft holes are disposed on the wall of the pipe sleeve. Hollow buttons are disposed in the two shaft holes and have openings towards the axis of the pipe sleeve. Slideways are disposed at the walls of the shaft holes on the pipe sleeve. Slide blocks installed in the slideways are disposed on the sidewalls of the hollow buttons. Two arc clamping blocks are disposed in the pipe sleeve and are arranged oppositely. Shaft rods are disposed on the centers of the outer arc surfaces of the two arc clamping blocks, are vertical to the respective arc clamping blocks, and are inserted into the corresponding hollow buttons. Compression springs are disposed in the hollow buttons. The shaft rods push the compression springs against the inner walls of the hollow buttons.
