Abstract

The invention discloses a circuit board control cabinet capable of shielding electromagnetic interference. The circuit board control cabinet capable of shielding electromagnetic interference comprises a cabinet shell (1), a ventilation system (2), a circuit board arrangement assembly (3), a fixing frame (6) and a lifting type circuit board opening assembly (7), wherein the cabinet shell (1) is used for containing the ventilation system (2), the circuit board arrangement assembly (3), the fixing frame (6) and the lifting type circuit board opening assembly (7) and is provided with a doorway region (8); the doorway region (8) is used for a user to operate and maintain the circuit board control cabinet; the ventilation system (2) is used for inputting cooling air into the cabinet shell (1); the circuit board arrangement assembly (3) is provided with a stand column shaft (31); multiple circuit boards (4 and 5) are mounted on the stand column shaft (31) from top to bottom in a pivoted mode; both the circuit boards can independently pivot relative to the stand column shaft (31).

Description

technical field [0001] The invention relates to a circuit board control cabinet of automation equipment, especially the maintenance of the circuit board control cabinet. Background technique [0002] Some large-scale automation equipment now requires a large number of circuit boards to control the actions of its various components due to its complex action control. [0003] In order to make the maintenance of the control circuit boards of the various components easier and provide a good operating environment for these circuit boards, generally all the circuit boards of the control components are uniformly installed in the electrical cabinet. [0004] However, due to the huge size of the circuit board, and due to the protection considerations involved in the industrial environment, the circuit board often has a heavy shell weight and internal weight, and the insertion force of the circuit interface is often required to be higher and more stable, which brings great difficultie...
