Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

See also Fig. 1 to shown in Figure 4, a kind of spring-piece type card connector comprises insulating body 10, contact terminal 20 and is fastened on shielding loam cake 30 on the insulating body 10, wherein:

This insulating body 10 is made by plastic material, and it is made of two side arms 11 and the substrate 12 that is connected in 11 of two side arms, by this two side arms 11 and substrate 12 forms one can ccontaining memory card plant accommodation space 13; The chute 111 that is arranged in two side arms 11 arbitrary side arms is provided with a card fixing apparatus 112, the compression spring 114 that described card fixing apparatus 112 comprises slide block 113 and acts on slide block 113, and be provided with one in order to locate or to withdraw from the self-locking device 115 of plug-in card in slide block 113, therefore self-locking device 115 can move in slide block 113 draw-in grooves along plug-in card strength when inserting memory card, and memory card located, push memory card self-locking device 115 releases when moving back card, memory card withdraws from.Be positioned on the substrate 12 of insulating body 10 and be fitted with conducting terminal group 121, be electrically conducted in order to the insertion card; Offer caulking groove 122 on its front end, this caulking groove 122 sets firmly for contact terminal 20.

Contact terminal 20, it is by the moulding of sheet metal integrated punching, and it comprises base portion 21 and the welding foot 22 that is extended by base portion 21 bendings, and this base portion 21 is embedded in the caulking groove 121 that substrate 12 front ends of insulating body 10 offer.

Shielding loam cake 30, it is also formed by the sheet metal integrated punching, its two bendings side is provided with prominent button 116 fastenings that the side is provided with outside a plurality of button holes 31 and insulating body 10 two side arms 11 and interferes fixing, the leading portion that is positioned at this shielding loam cake 30 is provided with a sinking shell fragment 32 at least, this sinking shell fragment 32 is to be extended by the surface 33 downward one of shielding loam cake 30 to form, and, but and then form the elastic switch that one group of identification card inserts state with the contact terminal 20 upper limb Elastic Contact that are embedded on insulating body 10 substrates 12.

Extremely shown in Figure 7 in conjunction with Fig. 5 again, Fig. 5 is the utility model plug-in card status architecture schematic diagram, wherein memory card 40 is accommodation space 13 insertions along the insulating body 10 of the utility model card connector, but be the state that do not inject fully, shield the sinking shell fragment 32 that is provided with on the loam cake 30 and still just contact with the contact terminal 20 that is embedded on insulating body 10 substrates 12 this moment, and this memory card 40 of decidable does not insert in the card connector by this; Fig. 6, Fig. 7 are status architecture schematic diagram and sectional structure schematic diagrames behind the utility model plug-in card, as can be seen from the figure, when memory card 40 continues to advance to accommodation space 13, after being fully the insertion state, this memory card 40 is isolated sinking shell fragment 32 and contact terminal 20, thereby memory card 40 inserts good as can be known; Therefore, utilizing memory card 40 whether to isolate contact condition between sinking shell fragment 32 and the contact terminal 20 discerns this memory card and whether correctly inserts the utility model card connector.

The utility model design focal point is that the contact terminal that the substrate by shielding sinking shell fragment of loam cake and insulating body is embedded is combined into one group of elastic switch, whether sinking shell fragment and contact terminal can be isolated after inserting by card and judge card insertion state, instant just can be directly, the state of identification card insertion apace.Card fixing apparatus by being provided with in the chute of insulating body one side arm simultaneously can make the plug-in card can accurate in locating, and in conjunction with firmly, is convenient to withdraw from plug-in card again.

The above, it only is the preferred embodiment of a kind of spring-piece type card connector of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
