Abstract

The utility model relates to an electronic slide key clamping mechanism, which is composed of a push rod, a shifting plate, and a frame, wherein one end of the shifting plate is vertically provided with a liftout plate, and the end of the liftout plate has an L-shaped slotted hole to form an inverse supporting plate; the appropriate position near the rear end of the frame is provided with an upward supporting hook plate bending backwards; furthermore, the rear end of the frame is folded with a hook-shaped groove plate, and thus the L-shaped slotted hole can slide into the supporting hook plate; as the push rod is pushed in, a card inserted in a card jack can be pushed out. The utility model has the advantages that the inverse supporting plate can be prevented from breaking to prolong the service life; furthermore, the integral thickness and the occupied space can be reduced.

Description

Electronics push-and-pull key snap fastener

The utility model relates to a kind of electronics push-and-pull key snap fastener, and it designs at various plug-type electronic cards, also may be implemented in positions such as computer format floppy machine.

Existing electronic cards push-and-pull key snap fastener (as shown in Figure 1, 2), it is made up of a push rod 10, the one group of plate 20 and a framework 30, and wherein, push rod 10 is the stock that an end is provided with frame hole 11; Dialling plate 20 is the lever of growing crosswise, one end of this group plate 20 upwards hangs down and is provided with a pin plate 21 that closes with frame hole 11 pivots of push rod 10, and upwards hanging down in the in addition end below of this group plate 20 does not have a section to be the liftout plate 22 of cambered surface, is provided with a rear support that colludes before being down in the appropriate location of this group plate 20 again and colludes plate 23; Framework 30 is the seat board that card connector 40 can be fixed, one side of this framework 30 is rolled and is converted into a chute frame 31 that can supply push rod 10 to slide, and folding is rolled in the both sides of this framework 30 fixedly flap 32, offer pilot hole 33 on this flap 32, this pilot hole 33 can be with location lug 41 location of card connector 40 both sides, the appropriate location of these framework 30 nearly rear ends is provided with one to the curved dihedral perforation 34 in bottom right, this dihedral perforation 34 can be used as the supporting node of dialling plate 20, folding is rolled in the rear end of this framework 30 a hook-shaped frid 35, allowing the rear support of dialling plate 20 collude plate 23 can wear and slip in the dihedral perforation 34, and be subjected to the constraint of this frid 35, to prevent that dialling plate 20 deviates from framework 30.

Aforesaid rear support colludes plate 23 (as Fig. 3) evagination in the bottom of framework 30, so that whole height thickening, moreover, this rear support colludes plate 23 and is subjected to the acting force of push rod 10 and the constraining force of dihedral perforation 34 repeatedly, produce bigger nodal force (supporting power), often cause rear support to collude plate 23 fracture and entire mechanism is damaged and scrap.

Because above-mentioned deficiency, fundamental purpose of the present utility model is rear support plate intensity height, not fragile, and the less electronics push-and-pull key snap fastener of integral thickness.

The utility model adopts following scheme to finish above-mentioned purpose: electronics push-and-pull key snap fastener, it comprises a framework, one push rod and one group of plate, this push rod is the stock that an end is provided with the frame hole, one end of this group plate hangs down and to be provided with a pin plate that closes with the frame hole pivot of push rod, and the end in addition of dialling plate hangs down and is provided with a liftout plate, this framework is the seat board that card connector is fixing, one side of this framework is rolled and is converted into a chute frame for described push rod slip, and folding is rolled in the rear end of this framework a hook-shaped frid, it is characterized in that: the appropriate location of the nearly rear end of described framework washes off into palintrope and plate is colluded in the supporting that makes progress, and the rear end appropriate location of this group plate is offered one and can be worn and slip into described supporting and collude slotted eye in the plate.

The turning point, bottom of liftout plate is provided with a sags and crests that can promote the bending strength of this liftout plate.

The end in addition of dialling plate can hang down and establish more than one liftout plate.

The utility model is with the dihedral perforation of original framework, change is colluded plate with the supporting that washes off into palintrope and make progress, and will dial the original rear support of plate colludes plate and is removed, and offer one " L " shape slotted eye in the rear end of this group plate, form the rear support plate, so that " L " shape slotted eye can be slipped into supporting and collude in the plate, make the rear support plate have thicker supporting width, can prevent the fracture of rear support plate, prolong its life-span; But also can reduce whole thickness, thus reduced taking up room of parts, very help the miniaturization of machine.

Below in conjunction with drawings and Examples the utility model is further described.
