Description

The multipurpose memory card connector

Technical field

The utility model belongs to the data medium servicing unit, particularly a kind of multipurpose memory card connector.

Background technology

Computer technology is grown up with the speed of making rapid progress now, its computer development trend is also strong towards calculation function, fireballing direction strides forward, and be usually used in computer, the expansion memory body used in electronic dictionaries etc., the networking card, modem, scsi device is (as the high power capacity hard disc, scanner) electronic cards, canonical form on its card computer is PCMCIA (Per sonal Computer Memory Card International Association), general PCMCIA also has the design that is converted to other interface, as PCMCIA to SCSI, PCMCIA to IDE etc., all can make notebook computer be used the multiple interfare device of PC, in most of notebook computer, all support the ability of Plug and Play, even support hot plug (Hot Plug) function to start shooting again and just can directly use; Other has the electronic cards of other different types to can be applicable to the upward use of devices such as palmtop computer (PDA) and palm type electronic dictionary, so except the memory body pattern of PCMCIA, roughly still have MMC (Multi Media Card), CFC (Compact Flash Card), SMC (Smart Media Card) at present on the market, MS (Memory Stick), SDMC specifications such as (Secure Digital MemoryCard) can be for replacing.

Moreover the location structure of traditional electrical subcard and connector is that connector shell is fixed on the circuit board, is plugged in the connector with electronic cards again, reaches electronic cards and connector and fixes purpose of connecting.And because the pattern difference of various memory cards, its apparent size and shape are also variant, and make the memory card of different types, must be plugged on the specific pattern connector that is consistent with its pattern, can make connector read memory document in the memory card.The memory card of various different types is all inequality because of shape and size, also having different thickness for the connector of pegging graft cooperates, its thickness is if surpass more than the 4.2mm, then can't use for notebook computer, connector promptly can't be installed on the circuit board of notebook computer, therefore, the connector that uses for notebook computer must thickness less than just being installed on the circuit board of notebook computer below the 4.2mm.For example to be stuck in the canonical form on the computer be PCMCIA to electronics, its thickness be restricted to 4mm, therefore the space of pegging graft for memory card also dwindles relatively, inserting mode of memory card and connector so, can be subjected to the restriction of connector form in use, can't substitute and use different memory cards, thereby, the connector of multiple different types must be set on circuit board, also make the enlarged areas of circuit board, occupation space also increases relatively, makes circuit board can be subjected to the multiple restriction of volume, space size in use.And the upper and lower staggered stacked mode of most employing that is provided with of its internal terminal of connector of commonly using is arranged plural terminals.Yet so the terminal arrangement mode needs bigger locus, also causes thickness increase, the volume of connector to strengthen relatively, can take more space during use.Multiple disappearance and inconvenience that many use restrictions of connector of commonly using as mentioned above and memory card are produced promptly become relevant dealer and desire most ardently the direction place that research improves.

Summary of the invention

The purpose of this utility model provides a kind of multiple different size memory card, little, simple and easy card connector of multipurpose memory fast of pegging graft of volume of being applicable to.

The utility model comprises insulating base frame, be arranged at the upper cover plate that plural groups terminal in the insulating base frame and fixed cap are located at the insulating base frame top; Insulating base frame one side is the butt joint end face, is provided with the docking groove of the plural different size of pegging graft for the different size memory card in the past insulating base frame inside of butt joint end face, and three sides of docking groove inside extend to the corresponding side of insulating base frame; One end of plural groups terminal is provided with the butt end, and its other end is provided with terminal supportor; The plural groups terminal is arranged at three side edge of docking groove inside respectively, and the butt end of each terminal is stretched in the insulating base frame docking groove, and its terminal supportor then extends outside the corresponding side of insulating base frame docking groove, and forms the docking section outside three sides respectively.

Wherein:

The docking groove that is arranged at insulating base frame butt joint end face is first, second and third and four docking grooves of four kinds of different sizes.

Be provided with plural groups terminal in the insulating base frame corresponding to first, second and third and four docking groove different sizes of different size.

State in an overlapping between each docking groove of insulating base frame butt joint end face array different size.

Be overlapped in second docking groove and the 4th docking groove the 3rd docking groove for forming between SDMC type memory card second docking groove of pegging graft and the 4th docking groove of pegging graft for the grafting of MS type memory card for SMC type memory card.

Three sides of insulating base frame docking groove inside extend to the bottom of the corresponding side of insulating base frame; The terminal supportor length of plural groups terminal is identical with insulating base frame thickness; The terminal supportor that is arranged at plural groups terminal in each docking groove extends to the corresponding side outer bottom of insulating base frame, to form the docking section that extends to the insulating base frame bottom respectively.

Three sides of insulating base frame docking groove inside extend to the corresponding side appropriate location of insulating base frame; The terminal supportor length of plural groups terminal is less than insulating base frame thickness; The terminal supportor that is arranged at plural groups terminal in each docking groove extends to the corresponding side appropriate location of insulating base frame, to form the docking section that is positioned at the insulating base frame side respectively.

The mode that planar alignment is adopted with its butt end by plural groups terminal system is arranged in each docking groove of insulating base frame.

Because the utility model comprises insulating base frame, be arranged at the upper cover plate that plural groups terminal in the insulating base frame and fixed cap are located at the insulating base frame top; Insulating base frame one side is the butt joint end face, is provided with the docking groove of the plural different size of pegging graft for the different size memory card in the past insulating base frame inside of butt joint end face, and three sides of docking groove inside extend to the corresponding side of insulating base frame; One end of plural groups terminal is provided with the butt end, and its other end is provided with terminal supportor; The plural groups terminal is arranged at three side edge of docking groove inside respectively, and the butt end of each terminal is stretched in the insulating base frame docking groove, and its terminal supportor then extends outside the corresponding side of insulating base frame docking groove, and forms the docking section outside three sides respectively.During assembling, the utility model is fixedly arranged on the circuit board, and extends with it that the circuit work electrically contacts on docking section that corresponding side terminal supportor of insulating base frame docking groove forms and the circuit board.During use, the memory card of different size is inserted in the docking groove corresponding with it from the pedestal butt joint end face that insulate, with the metal interface of memory card and place one group of terminal group of corresponding docking groove to do electrically contact, promptly simple and easy, apace memory card is inserted in the docking groove.Be not only applicable to multiple different size memory card, and volume is little, it is simple and easy quick to peg graft, thereby reaches the purpose of this utility model.
