Abstract

A noise-reduction fixing column device applied to PCBs is used for being fixedly connected with a frame body (1) so as to fix a PCB (2) to the frame body (1). The fixing column device comprises a fixing body (8) of which the bottom is fixedly connected with the frame body (1). The fixing body (8) comprises a bottom shoulder part which is provided with a shoulder surface (81) used for carrying the back of the PCB, and a vertical column part (9) which is formed integrally and is perpendicular to the shoulder surface (81). The vertical column part (9) comprises a bottom cylindrical root (92) which is integrally connected with the shoulder surface (81) and is used for being jointed with a fixed hole in the PCB, a cylindrical top (91) which is disposed at the end of the top, and a middle connecting part which is between the cylindrical root (92) and the cylindrical top (91) and is shaped as a cylinder as a whole.

Description

technical field [0001] The invention belongs to the field of PCB circuit boards, and more specifically relates to a noise-reducing fixing post device for PCB circuit boards. Background technique [0002] Generally speaking, the installation of the PCB circuit board in the bracket of the equipment needs to be stable and reliable. The commonly used method or method is to punch holes on the control box, first install the pad nails for fixing the circuit board, and then pad the insulating gasket to fix the circuit board on it with screws, which can also be fixed with glue. [0003] However, this installation method requires manual screw tightening, and in some occasions where space is limited or operation time is limited, this fixing method is limited. [0004] Some existing fixed installation methods also include the use of plastic fixing nails with elastic hooks. In this way, the step of manually tightening the screws can be eliminated, and the circuit board can also be fixe...
