Wall bushing for cable connection

The invention relates to a wall bushing for cable connection. The wall bushing comprises a sleeve and a conducting rod, the conducting rod is fixedly connected to the inner ring of the sleeve, and the two ends of the conducting rod protrude out of the two ends of the sleeve and are provided with first threaded holes. The two ends of the sleeve are in a boss shape, the middle of the sleeve is cylindrical, a plurality of protruding blocks are evenly and fixedly connected to the outer ring of the middle position of the sleeve, second threaded holes are formed in the protruding blocks, and the axes of the second threaded holes are flush with the axis of the sleeve. The electric conduction of the cables at the two ends is achieved through the conducting rod, the structure is simple, operation is easy, meanwhile, the wall bushing does not need to be filled with any oil or gas medium, excellent electric conduction is achieved through the solid conducting rod, in the using process, the pollution problem is avoided, a
