Abstract
A fixed part comprises a cylinder, a boss and a clamping part, wherein the top end of the cylinder is provided with a screw hole, the boss is arranged at the bottom end of the cylinder and stopped on the top surface of a mainboard, and the clamping part is arranged on the bottom surface of the boss. The clamping part comprises a connecting part and a stopping part. The stopping part comprises a fixed piece, a protrusion and an arc-shaped cantilever extending upwards, wherein the fixed piece is connected to the bottom surface of the connecting part; and the protrusion and the cantilever are respectively connected to two ends of the fixed piece and stopped on the bottom surface of the mainboard. The boss, the protrusion and the cantilever are respectively stopped on the top surface and the bottom surface of the mainboard, the fixed part can be stably fixed on the mainboard, and accordingly an expansion card can be firmly fixed on the mainboard.
Description
Technical field
The present invention relates to a kind of fixture.
Background technology
Part expansion card is often directly fixed on mainboard by pressing screw.But because pressing screw is to be fixed in the hole of mainboard by the pressing threaded portion of bottom, in the time being subject to External Force Acting, this pressing threaded portion is easily loosening, cannot steadily fix expansion card, easily causes the signal interruption between expansion card and mainboard.
Summary of the invention
In view of more than, be necessary to provide one can securely expansion card be fixed on to the fixture on mainboard.
A kind of fixture, be included in a cylinder that top offers screw, be located at this cylinder bottom block in a boss of a mainboard end face and be located at a holding division of this boss bottom surface, this holding division comprises a junction and a stop section, and this stop section comprises and is connected in a fixed part of this connecting portion bottom surface, the two ends that are connected to this fixed part block in a projection of the bottom surface of this mainboard and the cantilever of a upwardly extending arc.
Compare prior art, the boss of this fixture and projection and cantilever respectively block, in end face and the bottom surface of mainboard, can firmly be fixed on mainboard by fixture, thereby an expansion card can be firmly fixed to mainboard.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1, the preferred embodiments of fixture 10 of the present invention is in order to be fixed on a mainboard 50 by an expansion card 40.
This expansion card 40 is offered respectively a perforation 42 in four jiaos.
This mainboard 50 offers four square pilot holes 52 to perforation 42 that should expansion card 40.
Please refer to Fig. 2, this fixture 10 comprises a cylinder 11, is located at a boss 20 of these cylinder 11 bottoms and is located at one of these boss 20 bottom surfaces holding division 30.
This cylinder 11 offers a screw 12 vertically in top.
In present embodiment, this boss 20 is square, and the length on its left and right directions is greater than the diameter of this cylinder 11.
This holding division 30 comprises a holding section 32, a junction 34 of being located at these 32 bottom surfaces, holding section and a stop section 36 of being located at the length on these boss 20 bottom surfaces and this holding division 30 be less than this boss 20 left and right directions along the length of left and right directions.This holding section 32 is square, and comprises relative vertical left surface 320 and a vertical right flank 322.This connecting portion 34 comprises one with one of coplanar the first side 342 of this left surface 320 and is connected in the second side 344 of an arc at contiguous right flank 322 places of the bottom surface of the Yu Gai holding section, bottom 32 of this first side 342.This stop section 36 is generally curved, comprise the fixed part 360 being connected with one end near this first side 342 of the second side 344 of this connecting portion 34, be connected in stretching out the projection 362 in these 342 left sides, the first side and be connected in the second end of this fixed part 360 and the cantilever 364 of the arc that extends towards this right flank 322 of first end of this fixed part 360.
Please refer to Fig. 3 and Fig. 4, when use, each pilot hole 52 of this mainboard 50 is equiped with a fixture 10.The projection 362 of this fixture 10 through the pilot hole 52 of correspondence also block in the bottom surface that is positioned at these pilot hole 52 1 sides of this mainboard 50.Press down afterwards this fixture 10, the cantilever 364 of this fixture 10 is subject to the extruding of hole wall of this pilot hole 52 and elastic deformation, until this cantilever 364 through this pilot hole 52 block in the bottom surface that is positioned at these pilot hole 52 opposite sides of this mainboard 50.Now the left and right side 320 and 322 of this fixture 10 is sticked in the hole wall of this pilot hole 52.Boss 20 blocks of this fixture 10 are in the end face of this mainboard 50, thereby this fixture 10 is firmly fixed on to this mainboard 50.
Afterwards this expansion card 40 is placed in to the top of these fixtures 10, four screws 60 through perforation 42 the corresponding screw 12 of locking these fixtures 10 of this expansion card 40, are firmly fixed on this expansion card 40 on this mainboard 50 respectively.
