See also Fig. 3 to shown in Figure 10, the utility model comprises location body 10 or 10a or 10b and nut body 20; Wherein this location body 10 or 10a or 10b be eye-splice on electronic card coupler 40, and this nut body 20 is stably to be buckled on this location body 10 or 10a or the 10b.Because in this nut body 20, be provided with the screw 23 of polydonita, can effectively avoid screw 30 passing circuit board 50, and rotation is when locking in the screw 23 of nut body 20, and is excessive because of the application of force, and the reaming phenomenon of locking takes place, make screw 30 can't be locked on shortcoming in the screw 23 again, with this electronic card coupler 40 of certain locking, and make the bottom of this location body 10 or 10a or 10b tightly be overlapped in an earthed circuit of circuit board 50, form ground connection.

As Fig. 3, Fig. 4, Fig. 6, Fig. 7, shown in Figure 8, location body 10 or 10a that the utility model disclosed, be by the moulding of sheet metal integrated punching, contain a baseplate part 11, be equipped with a hole 111, one lateral margin of this baseplate part 11, projection one cramp portion 12 radially, with eye-splice in this electronic card coupler 40, and in this cramp portion 12, elasticity projection one shell fragment 121 at least, stretch the chute 41 that places this electronic card coupler 40 when making this shell fragment 121 flat, make electronic cards 42 connect at 40 o'clock, but these shell fragment 121 elastic top are pressed on the lateral margin of electronic cards 42, with ground connection along chute 41 insertion electronic cards.

Above-mentioned location body 10 or 10a wherein in hole 111 outer rims of this baseplate part 11, are provided with several button pawls 112, accordingly this nut body 20 is buckled on this baseplate part 11. Location body 10 or 10a that the utility model disclosed, in these baseplate part 11 projections in the relative both sides of this hole 111, the prominent respectively tongue piece 110 of establishing, on each tongue piece 110, be equipped with button pawl 112 towards these hole 111 directions, to be snapped in the top ora terminalis 20a of nut body 20 by the button pawl 112 on this two tongue piece 110, upwards break away to stop this nut body 20.

As Fig. 9, shown in Figure 10, location body 10b of the present utility model also can be on the baseplate part 11 of these hole 111 outer rims, and is positioned at 110 of two tongue pieces, is equipped with stopper 113, relying on nut body 20, lateral margin, to stop this nut body 20 ' lateral sliding.

Extremely shown in Figure 8 as Fig. 3, location of the present utility model body 10 or 10a, wherein in lateral margin in the radially prominent cramp portion 12 that establishes, also be equipped with overlap joint tongue piece 122, at ordinary times with metal enclosing cover 43 overlap joints that are cross-placed on the electronic card coupler 40, make this metal enclosing cover 43 by the earthed circuit ground connection of location body 10, to cover extraneous electromagnetic interference with circuit board 50.

Nut body 20 of the present utility model as Fig. 3, Fig. 4, shown in Figure 8, comprises a body 21, makes hole 111 apertures of the external diameter of this body 21 greater than location body 10, is cross-placed on this hole 111 with stable.In the bottom of body 21, be equipped with a shaft part 22 in addition, the central shaft of this shaft part 22 is set in the hole 111 of this location body 10 this shaft part 22 to running through a screw 23 certainly, to stop this nut body 20 lateral slidings.But the shaft part 22 of above-mentioned nut body 20 as Fig. 9, shown in Figure 10, can be exempted to establish, and substitutes with general existing nut body 20 '.

As Fig. 5, shown in Figure 6, the fixture construction of the utility model electronic card coupler, wherein should locate body 10a, side at baseplate part 11, the fixing cramp 13 of projection one radially also, should be fixedly the lateral margin of cramp 13 be equipped with ratchet 131, with eye-splice firmly in the corresponding button hole of this electronic card coupler 40.

The fixture construction of the electronic card coupler shown in the utility model, when assembling, as shown in Figure 6, can earlier nut body 20 be buckled on location body 10, the 10a, cramp portion 12 eye-splices that to locate body 10,10a again are in the side arm of the both sides of electronic card coupler 40, this location body 10,10a are anchored on the electronic card coupler 40, after then passing a circuit board 50 with screw 30, lock the screw 23 that is buckled in the nut body 20 on the body 10 of location, so that electronic card coupler 40 is anchored on the circuit board 50, as Fig. 7, shown in Figure 8.Because in the fixture construction that the utility model disclosed, screw 23 in order to the nut body 20 of interlocking screw 30, be not to take out extrusion forming from baseplate part 11 one of thickness location body 10 as thin as a wafer, therefore can be with the increase of nut body 10 thickness, and increase formed tooth number in this screw 23, promptly this screw 23 can have the pitch height more than 3 times, with this screw 30 of interlocking stably, and can effectively avoid the lock phenomenon.

The fixture construction of the utility model electronic card coupler has following feature and advantage:

1, the stable nut body that is snapped on the body of location is owing to be a stand-alone assembly, therefore with the increase of its thickness, can wear the screw of several teeth, for screw locking electronic card coupler, can effectively avoid in the locking process lock phenomenon excessively that produces because of active force is excessive.

2, nut body can avoid screw to get loose phenomenon because of sustained vibration with the screw interlocking screw of several teeth, to improve the locking effect.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
