Embodiment Construction

[0013] Please refer to figure 1 , a preferred embodiment of the circuit board fixing device of the present invention includes a circuit board 10 , a case 20 and a fixing member 30 .

[0014] On the circuit board 10 , a buckle 12 protrudes forward from two ends of the front side edge 11 . Each buckle 12 is L-shaped and includes a neck 121 connected to the front edge 11 and a hook portion 123 bent leftward from the front end of the neck 121 . Two through holes 15 are defined near the front edge 11 in the middle of the circuit board 10 .

[0015] The case 20 includes a bottom plate 21 and a side plate 23 vertically extending upward from a front side of the bottom plate 21 . The side panel 23 is adjacent to the bottom panel 21 and has two horizontally extending elongated slots 25 horizontally spaced apart. The side plate 23 defines a locking hole 27 between the two locking slots 25 .

[0016] Please refer to figure 2 The fixing member 30 includes a base 31, a support arm 32 ...

Abstract

The invention relates to a circuit board fixing device which comprises a machine case, a circuit board and a fixing piece. The machine case comprises a lateral plate which is provided with at least one clamping groove and a clamping hole, the front lateral edge of the circuit board is provided with at least one L-shaped clamping buckle in a convex mode, the clamping buckle comprises a neck part and a hook bucking part, the neck part is connected to the front lateral edge, the front end of the neck part is leftwards bent to form the hook bucking part, the fixing piece is installed at the position, close to the front lateral edge, of the circuit board and comprises an elastic arm and a clamping hook arranged on the front side of the elastic arm in a convex mode, the clamping hook is rightwards provided with a stopping face, the clamping buckle penetrates through a clamping groove of the lateral plate to enable the neck part to abut against the left end of the clamping groove, the hook buckling part is arranged on the front side of the lateral plate in a stopped mode, the clamping hook is clamped into the clamping hole under the elastic effect of the elastic arm to enable the stopping face to abut against the right end of the clamping hole, and the circuit board is perpendicularly fixed on the lateral plate. By means of the circuit board fixing device, the circuit board can be fixed to the machine case without lock screws, installation space is saved, and the circuit board fixing device is convenient to operate.

Description

technical field [0001] The invention relates to a circuit board fixing device. Background technique [0002] In servers, it is often desirable to mount circuit boards adjacent side walls within the chassis. The existing fixing method is usually to pass through the circuit board with a number of screws and fix it to a number of fixing posts on the bottom plate of the chassis. However, this fixing method is inconvenient to operate and requires a large installation space. Contents of the invention [0003] In view of the above, it is necessary to provide a circuit board fixing device that saves space and is easy to operate. [0004] A circuit board fixing device, comprising a case, a circuit board and a fixing piece, the case includes a side plate, the side plate is provided with at least one card slot and a card hole, the front side edge of the circuit board is protruded with a At least one L-shaped buckle, the buckle includes a neck connected to the front side edge and a...
