Abstract

The invention discloses a fixing column device used for PCB, driven by a chain and provided with an elastic ejection piece. The fixing column device can be fixedly connected with a frame body (1) to fix a PCB (2) on the frame body (1); the fixing column device comprises a fixing body (8), wherein the bottom of the fixing body (8) is fixedly connected with the frame body (1); the fixing body (8) comprises a bottom shoulder part for bearing a shoulder surface (81) of the back surface of the PCB, and an integrally formed vertical column part (9) which is vertical to the shoulder surface (81); the vertical column part (9) comprises a cylindrical root (92), a cylindrical top (91) and a middle connection part; the cylindrical root is arranged at the bottom of the vertical column part (9), is integrally connected with the shoulder surface (81) and is combined with a fixed hole in the PCB; the cylindrical top (91) is positioned at the tail end of the top of the vertical column part (9); the middle connection part is arranged between the cylindrical root (92) and the cylindrical top (91) and is in a cylinder shape wholly.

Description

technical field [0001] The invention belongs to the field of PCB circuit boards, and more specifically relates to a fixed column device for PCB circuit boards driven by a chain and equipped with elastic ejectors. 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,...
