The invention discloses an anti-interference control box for a line controller, comprising a control box shell and a control circuit board arranged in the control box shell, wherein the control circuit board is connected with the line controller arranged at the outer side of the control box; the control box shell is made of an injection molding material; and a sealed metal layer capable of shielding external electromagnetic wave is added in the injection molding material. In the anti-interference control box, the sealed metal layer is added in the injection molding shell of the control box, and can shield the external electromagnetic wave, so that the interference to an internal electronic element is resisted, the interference of the external electromagnetic wave to the control box is prevented and signal communication is guaranteed. The sealed metal layer is in the injection molding shell, so that the insulativity of the injection molding shell to the inside and outside can be guaranteed.
