Abstract

The invention claims a fixing column device with an ejector for a PCB. The fixing column device is used for fixedly connecting a frame body (1) so as to fix the PCB (2) on the frame body (1). The fixing column device comprises a fixed body (8) of which the base is fixedly connected with the frame body (1); the fixed body (8) comprises a base shoulder part having a shoulder side (81) for bearing the back of the PCB, and an integrated perpendicular column part (9) perpendicular to the shoulder side (81); and the perpendicular column part (9) comprises a cylindrical root part (92) which is located at bottom, integrally connected with the shoulder side (81) and used for jointing a fixing hole on the PCB, a cylindrical top part (91) located at top end, and a generally cylindrical middle connection part located between the cylindrical root part (92) and the cylindrical top part (91).

Description

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