Embodiment
Please with reference to Fig. 1 and Fig. 2, the preferred embodiments of circuit board fixation structure 10 of the present invention can be used for the fixedly circuit board of different-thickness, and this circuit board fixation structure 10 comprises a substrate 30, some stiffening rings 40, some support columns 50 and some locking parts.In this execution mode, these locking parts are some bolts 60.
This substrate 30 can be the plate body that a part of of computer casing or is fixed in computer casing.This substrate 30 is offered the fixing hole 32 of some respectively corresponding these stiffening rings 40.
Please with reference to Fig. 3, each stiffening ring 40 comprises a circular packing ring 42 and a flange 44 from the less circle of the diameter of the end protrusion of this packing ring 42.Each stiffening ring 40 offer vertically one run through flange 44 screw 46.
Each support column 50 comprises that one has the main body 52 of regular hexagonal section and extended than first long thread segment 54 and the second short thread segment 56 from the two ends of this main body 52 respectively.This first thread segment 54 and second thread segment 56 all have external screw thread.Each support column 50 offer vertically one run through first thread segment 54 and second thread segment 56 screw 58.
Please in the lump referring to figs. 1 through Fig. 5; During assembling; The flange 44 of these stiffening rings 40 is penetrated respectively in the fixing hole 32 of this substrate 30, and through riveted joint or additive method these stiffening rings 40 are fixed on this substrate 30, the packing ring 42 of these stiffening rings 40 then protrudes from the surface of this substrate 30.
Install one thicker when having the circuit board 20 of some through holes 21; First thread segment 54 of these support columns 50 is screwed in respectively in the screw 46 of these stiffening rings 40; And this circuit board 20 is placed on second thread segment 56 of these support columns 50; And let the through hole 21 of this circuit board 20 aim at the screw 58 of these support columns 50 respectively; At this moment, can let through hole 21 and screw lock that these bolts 60 penetrate this circuit board 20 in the screw 58 of correspondence, thereby this circuit board 20 is fixed on these support columns 50.
Please with reference to Fig. 6; Install one thin when having the circuit board 70 of some through holes 71; Second thread segment 56 of these support columns 50 is screwed in respectively in the screw 46 of these stiffening rings 40; And this circuit board 70 is placed on first thread segment 54 of these support columns 50, and let the through hole 71 of this circuit board 70 aim at the screw 58 of these support columns 50 respectively, at this moment; Can let through hole 71 and screw lock that these bolts 60 penetrate this circuit board 70 in the screw 58 of correspondence, thereby this circuit board 70 is fixed on these support columns 50.
It is thus clear that; Circuit board for different-thickness; The user can select to let first thread segment 54 of these support columns 50 or second thread segment, 56 correspondences screw in the screw 46 of these stiffening rings 40; Side with installing electronic component on the circuit board that guarantees different-thickness is positioned at roughly the same height, and need not change the support column of differing heights to the circuit board of different-thickness, has practiced thrift cost.
In other execution modes, can in the fixing hole 32 of this substrate 30, internal thread be set, first thread segment 54 and second thread segment 56 of these support columns 50 just can be directly fixed in the fixing hole 32 of this substrate 30.In addition, first thread segment 54 of each support column 50 and second thread segment 56 also can respectively be offered the screw of a corresponding bolt 60.
