Abstract
The utility model relates to a pushing block structure of a card connector. A plurality of conductive terminals are penetrated through a containing space of an insulating base, and a pushing block is contained in the containing space. When a memory card is pushed into the insulating base, a plurality of contacts on the memory card are electrically connected with corresponding conductive terminals on the insulating base, a circulation device can be pressed for a second time by the memory card, and thus the pushing block is pushed, and the positioning or the card withdrawing state is formed, wherein the pushing block is provided with a clamping body which can be used for embedding and positioning the memory card, the clamping body is extended with an elastic arm which can be used for enhancing the elastic butting force, and thus when the memory card is inserted and positioned, the memory card is steady, the friction damage of a card slot can be prevented and the efficacy of smooth movement and memory card damage prevention can be achieved.
Description
Technical field
The utility model relates to a kind of passing block structure of card connector, refer to especially be provided with and can increase the fixing of the power of flexibly supporting body by passing piece, and then it is smooth and easy and prevent the effect that storage card damages to reach the storage card action.
Background technology
Flash memory is just strong because of calculation function since coming out, speed is fast, the expandability height, the characteristic that high storage density etc. are charming, in many portable devices, gradually replace EEPROM (voltage cancelling programmble read only memory PROM) or battery powered internal memory, because semiconductor technology progresses greatly day by day at present, the storage density of flash memory and transmission speed have the growth of advancing by leaps and bounds especially, therefore flash memory directly replaces traditional Storage Medias such as hard drives especially in many application, because flash memory has above-mentioned all multi-functional and characteristic, just there is relevant dealer to utilize flash memory and develops and all types of storage cards, as typical storage card is PCMCIA (Personal Computer memory Card International Association), roughly still has MMC (Multi Media Card) at present on the market, CF (Compact Flash Card), SMC (SmartMedia Card), MS (Memory Stick), SD (Secure Digital Memory Card), XD specifications such as (xD-Picture Card) can be for replacing, and this type of storage card promptly has been subjected to consumers in general's favor since coming out, and become a kind of almost indispensable tool using, and employed relatively card connector is also with increase in demand.
And existing card connector such as TW certificate number M241835 " Micro-card connector location and card-withdrawing structure ", see also Fig. 7, shown in 8, for the stereo appearance figure of prior art and overlook action diagram, by being clear that among the figure, prior art has been taken in a sliding part B on the framework A1 of body A one side, and sliding part B utilizes a spring C and body A to form binding, this sliding part B is provided with one and extends bootstrap block B1 in the rear end, front end then is provided with an action hook part B2, and slightly be provided with a leading slope part B3 in the rear in action hook part B2, thus when miniature cards D inserts connector, the end oblique angle D1 of miniature cards D is the leading slope part B3 of close interlock sliding part B then, and make the action hook part B2 of sliding part B be inserted in the positioning port D2 of miniature cards D, and form the state of miniature cards D location; Yet, the design that this kind sliding part B is one of the forming, so action hook part B2 and sliding part B is all plastic material and volume is bigger, and do not have the power of flexibly supporting, therefore be easy to when advancing card or moving back card, the positioning port D2 of action hook part B2 scratch miniature cards D or the surface of miniature cards D, even cause positioning port D2 to break because of scraping to decrease, finally cause miniature cards D to can't bear to use, moreover, because this kind sliding part B is one of the forming and makes, make the size of action hook part B2 be restricted, can't make more small size, so the suitable kind of miniature cards D also is restricted.
Therefore the dealer proposes the application of another existing connector again, announce " the advance and retreat card device of connector " No. 551674 as TW, see also shown in Figure 9, the action diagram of overlooking for another prior art, by being clear that among the figure, it is provided with sliding part F in insulating base frame E one side, and sliding part F front end is positioned with positioning piece G, this keeper G has the backstay G1 of a microscler flat, and utilize this backstay G1 to be positioned in the groove of sliding part F, and be extended with a hook part G2 in backstay G1 front end, thus, when storage card H inserts insulating base frame E, keeper G is laterally pushed against by storage card H and moves, sliding part F promptly is subjected to the pushing and pressing of storage card H and moves towards insulating base frame E bottom synchronously, and at this moment, the hook part G2 of keeper G then just snaps into the short slot H1 of storage card H and forms positioning states; This kind sliding part F must be positioned with the backstay G1 of its microscler flat in the groove of insulating base frame E, make insulating base frame E must cooperate the length of backstay G1 and open a darker groove, so will cause the intensity of insulating base frame E to reduce, and the degree of difficulty when increase making insulating base frame E and cause the increase of manufacturing cost, moreover, backstay G1 is that microscler flat so elastic force are obviously not enough, if want to increase the elastic force of backstay G1, then must increase the length of backstay G1, will cause the increase of manufacturing cost thus.
So, how to solve the above problems and defective, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
Summary of the invention
Main purpose of the present utility model is to overcome the deficiencies in the prior art and defective, a kind of passing block structure of card connector is provided, pass piece and be provided with the fixing body that can be embedded the location for storage card, this fixes body and extends the elastic arm that can increase the power of flexibly supporting, feasible storage is stuck in when inserting the location firm more and can prevent the draw-in groove friction damage, and then it is smooth and easy and prevent the effect that storage card damages to reach action.
For reaching above-mentioned purpose, the utility model provides a kind of passing block structure of card connector, in the accommodation space of insulating base frame, be equipped with the complex conduction terminal, and be provided with stopper slot in complex conduction terminal one side, and in accommodation space, contain the passing piece, this passing piece is provided with guide groove can supply gag lever post locating slip thereon, and make the complex conduction terminal after storage card pushes insulating base frame, complex conduction terminal corresponding on plural contact and the insulating base frame on the storage card is formed to be electrically connected, and this storage card can secondary be pushed a circulation and is promoted to pass piece, form the location or move back the card state, wherein, the base portion of this passing piece is provided with the fixing body that can be embedded the location for the draw-in groove of storage card, and this fixes body and extends the elastic arm that can increase the power of flexibly supporting.
