Embodiment Construction

[0013] Please refer to figure 1 , The first preferred embodiment of the circuit board fixing device of the present invention includes a circuit board 10 , a case 20 , a first fixing member 30 , a second fixing member 40 and a locking member 50 . In this embodiment, the locking member 50 is a screw.

[0014] The circuit board 10 defines two pairs of through holes 12 spaced apart at the front edge 11 .

[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 plate 23 defines a gourd hole 24 and a through hole 25 at intervals adjacent to the bottom plate 21 . The gourd hole 24 includes a larger first hole 241 away from the through hole 25 and a smaller second hole 243 adjacent to the through hole 25 communicating with the first hole 241 .

[0016] The first fixing member 30 includes a main body 31 , a fastening portion 33 protruding from a front end of the main body 31 , and two elastic ...

Abstract

The invention relates to a circuit board fixing device which comprises a circuit board, a case, a first fixation piece with two clamp pins at the bottom, a second fixation piece with two clamp pins at the bottom and a lock piece. The case comprises a side board. The side board is provided with a through hole, a first hole and a second hole which is connected with the first hole, wherein the size of the second hole is smaller than the size of the first hole. The first fixation piece and the second fixation piece are clamped on the circuit board through the clamp pins. A neck part which passes through the first hole and is clamped in the second hole and a head part which is connected with the front end of the neck part and is stopped on the front side of the side board are arranged on the front end on the first fixation piece. A fixation hole is arranged on the front end of the second fixation piece. The lock piece passes through the through hole of the side board and is locked into the fixation hole of the second fixation piece. According to the circuit board fixing device, simply by sliding the circuit board, the first fixation piece is clamped on the side board; the lock piece is locked on the front side of the side board of the case to fix the second fixation piece; the circuit board is fixed on the case; and the circuit board fixing device has the advantages of saved installation space and convenient operation.

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 circuit board, a case, a first fixing part with two clips at the bottom, a second fixing part with two clips at the bottom and a locking part, the case includes a side plate, The side plate is provided with a through hole, a first hole and a second hole communicating with the first hole and having a s...
