Description

The slide device of card connector

Technical field

The utility model relates to a kind of slide device of card connector, especially referring to that the stopping body of slide device is one-body molded has blocking part and a support division, and can flexibly support and be resisted against the draw-in groove and the side of storage card respectively, and then reach the storage card contraposition and reach the firm effect in location really.

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 (Smart Media 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 indispensable tool using that is almost, and employed relatively card connector is also with increase in demand.

Therefore general dealer takes the facility of user when pegging graft or withdrawing from storage card into account, all a slide device can be set in insulating base frame, so, there is the dealer to propose novel patent application on November 28th, 2002, and announce the retreat-card device of No. 553529 card connector through TW, see also shown in Figure 6, three-dimensional exploded view for prior art, by being clear that among the figure, the card connector of prior art is provided with in the support arm A1 of insulating base frame A one side and passes space A11, taken in a passing piece B in the A11 of space and pass, and passing piece B utilizes a flexible member C and insulating base frame A to form binding, and the side of passing piece B is concaved with a guide rail B1, this guide rail B1 can be embedded slippage for a guide rod B2 who is the ㄇ type, and cover is covered with a loam cake D above insulating base frame A, so that the compressing sheet D1 and can be flexibly supported on guide rod B2 surface of loam cake D, can firmly be embedded at by the power that flexibly supports that compresses sheet D1 in the guide rail B1 that passes piece B side, and make guide rod B2 in guide rail B1, slippage also form location or sliding mode, be pressed into automatically and can reach, withdraw from the purpose of storage card.

Though yet the retreat-card device of above-mentioned card connector can reach automatically the effect that is pressed into, withdraws from storage card, still has following defective:

(1) the passing piece B of prior art cooperates the setting of loam cake D, though can reach automatically the effect that is pressed into, withdraws from storage card, but after storage is stuck in and inserts insulating base frame A, there is no the structure setting that prevents that the storage card deflection from rocking, feasible storage is stuck in to have after the insertion to rock and locate untrue situation and produces, even causes storage card to break away from and cause the serious consequence of data forfeiture.

(2) guide rod B2 need cooperate the set sheet D1 that compresses of loam cake D to press on guide rod B2 top to prevent guide rod B2 warpage or escape, what yet loam cake D was set compresses sheet D1 because its elasticity is not good, therefore after the long-term use of process, compress sheet D1 and then can produce deformation, make compress sheet D1 again elasticity press on guide rod B2 top, and then cause guide rod B2 to break away from and can't move, cause card connector to re-use the most at last.

(3) the guide rod B2 that passes piece B must cooperate compressing being provided with of sheet D1 and could moving of loam cake D, then can't use when piece B does not have the loam cake of setting D when passing, so not only reduce its practicality, and, also increase whole manufacturing cost because of cooperating the setting of loam cake D.

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 slide device of card connector is provided, utilize slide device to be provided with and to keep out in the stopping body of guide rod top, and the one-body molded blocking part that the draw-in groove that can be flexibly supported on storage card is arranged of this stopping body, and the support division that can be resisted against the storage card side is arranged, and then reach the storage card contraposition and reach the firm purpose in location really in a side of blocking part is also one-body molded.

For reaching above-mentioned purpose, the utility model provides a kind of slide device of card connector, in insulating base frame central authorities base portion two sides respectively towards having extended support arm in the same way, and in two arm rooms formation butt joint space, and contain slide device in butt joint space one side, this slide device is provided with the stopping body that can keep out in the guide rod top, and on insulating base frame, be equipped with the complex conduction terminal, can be and be provided with for the guide groove of the guide rod locating slip of slide device in complex conduction terminal one side, and after making the complex conduction terminal push the butt joint space of insulating base frame in storage card, 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 slide device, form the location or move back the card state, wherein: the one-body molded blocking part that the draw-in groove that can be flexibly supported on storage card is arranged of this stopping body, and a side of blocking part is also one-body molded that the support division that can be resisted against the storage card side arranged.
