The invention discloses an autonomous movable wire arrangement board in a switch cabinet. A plurality of interconnected track bars are arranged in the longitudinal direction and the transverse direction of a circuit board separately; movable backboards capable of moving along the track bars are arranged on the circuit board; bolts are arranged at the back side of each movable backboard; an insulating spacer is arranged at the front side of each movable backboard; and each insulating spacer is provided with a clamping part for clamping an electronic component. Compared with the prior art, the autonomous movable wire arrangement board in the switch cabinet has the advantages that the electronic components can be fixed on the circuit board through stable clamping of the clamping parts for theelectronic components, the movable backboards are pushed in the track bars according to the position requirements, and appropriate positions are selected for fixing, so that the autonomous movement of the electronic components to any position according to the wire arrangement environment can be achieved, a tradition fixed installation mode is changed, the wire arrangement board does not need to be dismantled when the positions of the electronic components are changed, a wire does not need to be replaced with another wire with an appropriate length, the space in the switch cabinet is reasonably utilized and space resource integration of component placement positions in the switch cabinet is completed.
