Abstract

A fixing column apparatus provided with an abrasion-resistant gasket and an elastic ejection part and used for a PCB (printed circuit board) is disclosed. The fixing column apparatus is used for being fixedly connected with a frame body (1) so as to fix the PCB (2) on the frame body (1); the fixing column apparatus comprises a fixing body (8), wherein the bottom of the fixing body is fixedly connected with the frame body (1); the fixing body (8) comprises a bottom shoulder part with a shoulder surface (81) used for bearing the back surface of the PCB and a perpendicular column part (9) that is integrally formed and perpendicular to the shoulder surface (81); the perpendicular column part (9) comprises a cylindrical root part (92) that is positioned at the bottom, integrally connected with the shoulder surface (81) and used for jointing with a fixing hole in the PCB, a cylindrical top part (91) that is positioned at the tail end of the top, and a middle connecting part that is cylindrical as a whole and positioned 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 post device with an anti-wear gasket and an elastic ejector for the PCB circuit board. Background technique [0002] Generally speaking, the installation of the PCB circuit board in the bracket of the equipment in use needs to be stable and reliable. The common way or method is to drill holes in the control box, first install the pad nails to fix the circuit board, and then put the insulating pads 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 with space constraints or operating time constraints, 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 boar...
