Abstract

The invention discloses a fixing column device with a cooling fan for a PCB. The fixing column device is used for being fixedly connected with a frame body (1) to fix the PCB (2) on the frame body (1), wherein the fixing column device comprises a fixed body (8) of which the bottom part is fixedly connected with the frame body (1); the fixed body (8) comprises a bottom circular bead part and a vertical column part (9); the bottom circular bead part comprises a circular bead surface (81) which is used for bearing the back surface of the PCB; the vertical column part (9) is integrally molded and is vertical to the circular bead surface (81); the vertical column part (9) comprises a cylindrical root part (92) at the bottom part, a cylindrical top part (91) and an intermediate connecting part; the cylindrical root part (92) is integrally connected with the circular bead surface (81) and is used for being engaged with a fixed hole in the PCB; the cylindrical top part (91) is located at the tail end of the top part; and the intermediate connecting part is arranged between the cylindrical root part (92) and the cylindrical top part (91) and is in a cylindrical form on the whole.

Description

technical field [0001] The invention belongs to the field of PCB circuit boards, and more specifically relates to a fixed column device with a cooling fan 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...
