See also Fig. 5, Fig. 6, reach Fig. 7, be the utility model first embodiment, it is the Express card connector that a kind of large and small card can be shared, and it comprises a metal shell 40, a plastic seat body 50, one oblique fairlead 60, reaches a driving and reversing mechanism 70, wherein:
This metal shell 40 is that sheet metal punching press bending forms, it is provided with an end face 41 and first and second relative side 42,43, the width of its leading portion both sides is wide than the width of back segment both sides, this first side 42 linearly, the front and rear sections of this second side 43 forms a drop, its second side, 43 back segment lower edges are provided with a plane 44 and a trip 45, its back segment both sides respectively are provided with a fixture 48, this fixture 48 is provided with a stator 49 and is positioned at first and second side 42,43 lower edges and protrudes laterally, can lock screw by this stator 49 and be fixed on the motherboard.
This plastic seat body 50 is located at these metal shell 40 back segments and is covered by this metal shell 40, and this plastic seat body 50 is provided with a link slot 51, and this link slot 51 is provided with spaced terminal (terminal is not characteristics of the present utility model, so figure does not show).
This oblique fairlead 60 is bent to form with these metal shell 40 one, it is that end face 41 by this metal shell 40 punctures and forms, the one end is a longitudinal part 61 and links to each other with these second side, 43 leading portion one, its other end is a horizontal part 62 separates and be positioned second side, 43 back segment lower edges with end face 41 a plane 44, this horizontal part 62 is these trip 45 fastenings, and this end face 41 forms an oblique slotted hole 46.
Please cooperate and consult Fig. 8 and Fig. 9, this driving and reversing mechanism 70 includes a movement 71, a push jack 86, a guide bar 80, reaches a spring 85, wherein:
This movement 71 is bent to form with these metal shell 40 one, its one is located at this second side, 43 back segments, it is provided with: a base plate 73, one interior track pad 74, one outer track pad 75 and a plurality of one way stop 76, wherein: track pad 74 is to be protruded by the plate face punching press of base plate 73 in this, the one end is tip 77, and the other end is first anchor point 78 that forms a depression near M shape; Should outer track pad 75 be that bending is positioned at the inboard of this base plate 73 and both are parallel, should outer track pad 75 be provided with in a perforate 79 should interior track pad 74 be surrounded on, form a chute 72 between this inside and outside track pad 74,75, this chute 72 is a circulating path 710, the tip 77 of being somebody's turn to do the interior track pad 74 of perforate 79 1 end correspondences of outer track pad forms second anchor point 711, perforate 79 other ends be nearly M shape to should in nearly M shape one end of track pad 74, make this end form a middle protuberance and two recesses, this two recess is respectively travel point 712 and moves back card starting point 713; These a plurality of one way stop 76 are to protrude from this base plate 73 punching presses, make this circulating path 710 from second anchor point, 711 → travel point, 712 → the first anchor points 78 → the move back unidirectional circulation of card starting point 713 → the second anchor points, 711 formation.
This push jack 86 is provided with a pushing portion 87, a fixing hole 88, reaches a hook part 89, and this pushing portion 87 can push for the memory card that inserts.
One end, 81 trips of this guide bar 80 are in the fixing hole 88 of this push jack 86, and the other end 82 is inserted in the chute 72 of this movement 71, and an end 82 that drives this guide bar 80 when this push jack 86 is promoted slides in this chute 72.
A hook part 89 and the other end that these spring 85 1 ends are fixed in this push jack 86 are fixed in this second side, 43 back segments.
Explanation by above sees also Figure 10, because these metal shell 40 back segments cooperate the width of kilocalorie 10, so kilocalorie 10 just can be sleeved in this metal shell 40, the link slot 51 that the joint 14 of its rear end directly inserts this plastic seat body 50 is electrically connected.
See also Figure 11 and Figure 12, when lesser calorie 15 if do not align when inserting, the protuberance 18 of bottom surface, lesser calorie 15 rear end can be butted on this oblique fairlead 60, is electrically connected so this lesser calorie 15 can move the link slot 51 that makes its joint 19 align this plastic seat body 50 by the guiding of this oblique fairlead 60.
Large and small card 10,15 all can push the push jack 86 of this driving and reversing mechanism 70 when inserting, see also Fig. 9, when the user pushes link slot with memory card backward, memory card promote this push jack 86 backward the time this push jack 86 drive this guide bar one end 82 and prolonging circulating path 710 to the trip point 712 by second anchor point 711, then the restoring force because of spring 85 makes this guide bar one end 82 get back to this first anchor point, 78 location when the user looses one's grip, and is the connection location of plug-in card this moment; The user only needs to push away card toward link slot again and then makes guide bar one end 82 prolong circulating path 710 by first anchor point 78 to move back card starting point 713 to this in the time will moving back card, this guide bar one end 82 is prolonging circulating path 710 to this second anchor point 711 because of the restoring force of spring 85 by moving back card starting point 713 when loosing one's grip again, be this moment moves back card position, and the user can take out memory card.
See also Figure 13, be second embodiment of the invention, Express card connector for a kind of lesser calorie of pegging graft, it is roughly identical with first embodiment, its difference is that the metal shell 40 of this example only can cooperate lesser calorie to be inserted in, so need not to set oblique fairlead, this movement 71 is identical with first embodiment to be to be located at metal shell 40 1 sides.
See also Figure 14, be third embodiment of the invention, be a kind of Express card connector of the lesser calorie of pegging graft, it is roughly identical with second embodiment, and its difference is that the movement 71 of this example is the end face that one is located at metal shell 40.
See also Figure 15, be fourth embodiment of the invention, Express card connector for a kind of kilocalorie of pegging graft, it is roughly identical with first embodiment, this movement 71 is identical with first embodiment to be to be located at metal shell 40 1 sides, right this example is not provided with oblique fairlead, uses so only can be suitable for kilocalorie.
The foregoing description all explains with Express card connector, yet relevant other are used the connector that driving and reversing mechanism is arranged when plug-in card, and its metal shell one is bent with the movement, and the person still belongs to range of application of the present utility model.
The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to be easy to illustrate technology contents of the present utility model, and be not with the utility model narrow sense be limited to this embodiment, in the situation that does not exceed spirit of the present utility model and claim, can make many variations and implement.
