A FIXING STRUCTURE OF MULTI-LAYER PRINTED CIRCUIT BOARD

摘要

A fixing structure of a multi layer printed circuit board is provided to improve efficiency of assembly and disassembly processes by firmly coupling a plurality of the printed circuit boards once. A penetration hole is formed in an edge of a plurality of printed circuit boards(10). A fixing unit of the printed circuit board includes a plurality of slots and a fixing groove. The edge of the printed circuit board is inserted into a plurality of slots. The penetration hole of the printed circuit board is exposed by a fixing groove. A coupling member(30) is guided according to the fixing groove. The coupling member passes through the penetration hole of the printed circuit board. The pair of the fixing units of the printed circuit board are separated and fix the both ends of the printed circuit board. A receiving unit with a predetermined depth is formed in the fixing unit of the printed circuit board. A plurality of ventilation holes(24) are formed in the receiving unit.
