[Embodiment] Please refer to FIG. 1 , the circuit board fixing device of the present invention is used for fixing a circuit board 1 于 in a casing. The preferred embodiment of the circuit board fixing device comprises a fixing frame 30 , a casing bottom plate 50 and a The snap fastener is 7〇. Two positioning holes 12 are vertically arranged at intervals in the vicinity of one side of the circuit board 10. The fixing frame 30 is mounted on the bottom plate 50. The fixing frame 3 is a door-shaped frame, and includes a first side plate 32, a second side plate 34, and a connecting first side plate 32 and a second side. The top cover 36 of the upper end of the plate 34. The first side plate 32 includes a substantially "L" shaped fixing portion 37. The fixing portion 37 includes a positioning plate 370 and a fixing plate 374. The positioning plate 370 is from the first slab 32. The edge of the end extends perpendicularly to the outside of the fixing frame 30. The positioning plate 370 is provided with two positioning posts 372 corresponding to the positioning holes 12 of the circuit board 1 °. The fixing plate 374 is from the side edge of the positioning plate 370. The other end of the one side plate 32 extends vertically. The fixing plate 374 is spaced apart from the three fixing wires 376. The fixing plate 374 is disposed adjacent to the fixing hole 376 of the uppermost end and is provided with a slot 378. The rear side edge of the plate 374 is bent to form a flange 377 (see FIG. 3). The second side plate 34 includes a limiting portion 38. The limiting portion 38 includes an extension plate 380 and a limiting plate 384. The extension plate 380 The side of the second side plate 34 opposite to the fixing portion 37 of the first side plate 32 is edged 13 135.3812. The edge is perpendicular to the outer side of the fixing frame 30 The upper and lower end edges of the extension plate 38 are folded away from the fixing frame 30 by a pressing piece 382. The limiting plate 384 is firstly extended from the side edge of the first side plate 34 of the extending plate 380 to the side away from the fixing frame 3〇. The white body extends vertically and then is bent in a direction perpendicular to the first side plate 32. One end of the bottom plate 50 is adjacent to the fixing portion of the first side plate 32, and two pivoting portions 52 are arranged side by side, and each pivoting portion 52 is disposed. A pivoting hole 54. Referring to Figure 2, the locking member 70 is substantially cylindrical, and the locking member includes a first side 72 and two opposite second sides 74 adjacent to the first side 72. A fixing leg 740 extends perpendicularly from each of the two sides of the lower end of the first side 72 of the fastener 70, and a rotating shaft 742 is vertically protruded from the end of each of the fixing legs 74 and the side of the second side. The two sides % extend a plurality of pressing blocks 7 - 44 respectively in a direction away from the first side surface 72. The first side surface 74 is provided with a groove adjacent to the top end, and the groove 746 is parallel to the edge of the second side surface 74 away from the A fixing piece is extended in a direction of a side surface 72, and the end portion of the fixing piece is further bent and extended into the groove 746. An elastic sheet 'fixing sheet and elastic sheet form an elastic "U", a type of locking piece. (4) A snap ring 76 is protruded outwardly from the elastic piece of the piece 76, and extends perpendicularly from the distal end of the elastic piece to the operation portion 762. Fastener 7. On the opposite side of the first side surface W, there are three studs 78 respectively corresponding to the fixing plate opening holes 376 of the fixing portion 37. The latching member 7 extends from the end face of the locking piece % away from the first side face 72 to a resisting block 79. Referring to FIG. 3 and FIG. 4 together, when assembling, the rotating shaft 742 of the fixing member 40 of the locking member 7 is respectively passed through the pivot hole of the corresponding pivoting portion μ, and the end of the locking member 70 is extremely The ground is fixed to the bottom plate 50. The end of the circuit board 1 滑 is slid into the limiting portion 38 of the second side plate 34 along the extension plate 380 of the second side plate 34 of the ninth 1353812, so that the limiting plate 384 of the limiting portion 38 is resisted at the end of the circuit board 1 〇 The two pressing pieces 382 of the extension plate 380 are respectively pressed against the upper and lower end edges of the circuit board 10. The positioning holes 12 of the circuit board 1 穿过 pass through the positioning posts 372 of the positioning plate 37 of the first side plate 32 to connect the circuit. The plate 1 is positioned on the holder 30. The snap fastener 7 is rotated such that the latch of the locking tab on the first side panel 32 presses against the edge of the slot 378 of the fixing plate 374 of the first side panel 32, and the locking tab is deformed by pressure to make the card of the locking tab 76 The buckles 378 are engaged with the fixing plate 374 of the fixing plate 374, and the three protruding posts of the locking member 7 are respectively engaged with the fixing holes 376 of the fixing plate 374.
