Description

Many card connectors

Technical field

The utility model relates to a kind of many card connectors, especially refer to a kind of connector that supplies multiple different types electronic memory card to peg graft, and then can effectively reduce the height of connector and dwindle shared volume, and can reduce number of connectors on the default wiring board simultaneously and increase the usage space of wiring board.

Background technology

Computing machine science and technology is grown up with the speed of making rapid progress now, the development trend of its computing machine is also strong towards calculation function, fireballing direction strides forward, and be usually used in computing machine, electronic dictionary etc., be used for Extended RAM, network card, modulator-demodular unit, scsi device is (as high capacity hard disk, scanner) is electronic cards, and the canonical form that electronics is stuck on the computing machine is PCMCIA (Personal Computer memory CardInternational Association), general PCMCIA also has the design that is converted to other interface, as PCMCIA to SCSI, PCMCIA to IDE etc., all can make mobile computer be used the multiple interfaces device of personal computer, in the middle of most mobile 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, thus, except the storage card pattern of PCMCIA, roughly still has MMC (MultiMedia Card) at present on the market, CF (CompactFlash Card), SMC (SmartMedia Card), MS (Memory Stick), SD specifications such as (Secure Digital Memory Card) can be for replacing.

Moreover, the location structure of traditional electrical subcard and connector, be that connector shell is fixed on the circuit board, again electronic cards is plugged in the connector, fix purpose of connecting to reach electronic cards and connector, and because the pattern difference of various storage cards, its apparent size and shape are also variant, and make the storage card of different types, must be plugged on the specific pattern connector that is consistent with its pattern, can make connector read data on file in the storage card, so storage card and connector inserting mode, can be subjected to the restriction of connector form in use, can't substitute and use different storage 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, allows circuit board can be subjected to volume in use, the multiple restriction of space size; Moreover, the multiple-card connector of prior art is greatly more than being positioned with a wiring board in the insulating base frame, then be positioned with another wiring board in loam cake again, and respectively at being positioned with a plurality of signal terminals and transmission terminal on two wiring boards, when last housing is overlying on the insulating base frame apical margin,, a plurality of signal terminal and transmission terminal electrically connect even forming; Yet, the design of prior art connector and assembling mode, need more assembled components and locus, so can cause the thickness of connector and volume to increase, and then can take more locus when causing using, and above-mentioned prior art connector is in the process of making, so because the more processing procedure that also can cause of member is comparatively numerous and diverse and manufacturing cost is also comparatively high, and many defectives of above-mentioned prior art and inconvenience are relevant dealer and desire most ardently the direction place that research improves.
