The invention provides an interconnected bracket in compatible with a weak electric line and a wiring method. The interconnected bracket comprises insulators, support plates, and a bottom plate connected with a wall body; the support plates comprise an upper support and a lower plate; the insulators comprise a first insulator for supporting an electric power line and second insulators for supporting a weak electric line; the first insulator is fixed at an upper plate of the upper support plate, the second insulators comprise a second upper insulator and a second lower insulator; the second upper insulator and the second lower insulator are fixed at an upper end and a lower end of the lower support plate, so that the interconnected bracket not only can be used for laying electric power line, but also is compatible with the laying of the weak electric line; an operation of arranging multiple brackets on the wall body is avoided, and the entire appearance of the wall body is improved; theelectric power line is located above the weak electric line, thereby preventing the weak electric line from hanging on the electric power line; the first insulator is fixed at an upper end of the upper support plate, thereby enlarging the distance between the electric power line and the weak electric line as much as possible, and further improving the use security of the interconnected line.
