Abstract

The invention discloses a grounding structure which comprises a housing and a metal support positioned in the housing, and at least one guide groove block connected with the metal support is further arranged in the housing; a heat radiation hole and a guide groove with a built-in fixing clamp are arranged on the guide groove block, and the guide groove penetrates the upper surface of the guide groove block along the axial direction of the guide groove block; a U-shaped clamping piece is arranged on the fixing clamp, two arms of the clamping piece are in shaped like arcs and protrude oppositely inwards, and the bottom part of the clamping piece is jointed with the metal support; and the metal support is jointed with the end of the guide groove block, and two ends of the metal support are fixed on the inner sides of the housing of a device. The grounding structure is simple, and can avoid the situation of leftward and rightward deviation of installation of a circuit board caused by deviation of the welding assembly process of the guide groove of the circuit board, lead the heat radiation performance to be good and lead the grounding performance to be stable.

Description

technical field [0001] The invention relates to a grounding structure, in particular to a grounding structure of industrial control equipment. Background technique [0002] For general industrial control equipment products, the circuit board is pushed in through the guide rail grooves scattered inside the device, and then the mounting nut on the circuit board is tightened to make it fully contact with the aluminum strip, and then it is integrated with the equipment shell, and finally grounded through the shell Terminals are connected to earth. [0003] With this grounding structure, when the circuit board is pushed in through the guide rail groove, the circuit board will shift left and right due to the deviation of the welding assembly process of the guide rail groove. If the equipment has multiple circuit boards that need to be arranged in parallel, it will cause The deviation of the groove causes the situation that other circuit boards cannot be assembled into the equipme...
