Abstract

The utility model relates to a card connector. A butt-joint space which can be inserted by preinstalled electronic cards is formed in an insulation stool body, and elastic bodies are respectively arranged at both sides of an opening of the butt-joint space. Guiding portions are arranged at the corresponding side edges of the two elastic bodies to make the guiding portions form an elastic and movable protecting rail. Therefore, the electronic cards with smaller widths can be guided to insert to avoid that when the electronic cards are inserted and pulled, the cards are easy to offset or swing because of inappropriate application of force, and terminals are caused to bend or break to make the electronic cards collide and damage or seized in the insulating stool body. Therefore, the electronic cards with different widths can be inserted in the same opening to make the card connector can be applied widely, and the purpose that the electronic cards with smaller widths can be more stable during the inserting and pulling procedure can be achieved simultaneously.

Description

Card connector

Technical field

The utility model relates to a kind of card connector, refers to especially when using the electronic cards of less width, can prevent in its plug process that electronic cards is offset or rocks, and then reach the more firm purpose of plug stroke of electronic cards.

Background technology

Computer science and technology is grown up with the speed of making rapid progress now, the development trend of its computer is also strong towards calculation function, speed is that the high direction of expandability strides forward soon, and generally all be to utilize the electronic card coupler electronic cards miscellaneous of pegging graft, for example: storage card, network card, modulator-demodulator, scsi device is (as high capacity hard disk, scanner) reaches the function of expansion, and electronic cards is applied to the canonical form of electronic product is PCMCIA (Personal 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 interfaces device of personal computer, in the middle of most 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 storage card pattern of PCMCIA, roughly still has MMC (Multi Media Card) at present on the market, CF (Compact Flash Card), SMC (Smart Media Cd), MS (Memory Stick), SD specifications such as (Secure DigitalMemory 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, be plugged in the connector with electronic cards again, reach electronic cards and connector and fix purpose of connecting, and because the pattern specification 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, so, just there is the dealer to research and develop a kind of connector that provides multiple different size storage card to peg graft is provided, see also shown in Figure 7, be existing three-dimensional exploded view, find out by knowing among the figure, this card connector includes insulating base frame A and shield shell B forms, the butt joint space A1 that wherein has the storage card (not shown) insertion that can supply different size in this insulating base frame A, then be provided with the different a plurality of terminal group B1 that arrange and can be electric connection on the shield shell B for the plurality of specifications storage card, moreover, when this kind card connector desires to accommodate the different size storage card, must the neither identical opening A11 of size and location be arranged in the design of butt joint A1 the place ahead, space, make things convenient for the storage card of different size to insert with this, yet, this kind designs when using, must be with storage card in alignment with opening A11 applicatory, but card connector all is tending towards light at present, thin, short, little designs, so, its storage card is difficult for aiming at opening A11 applicatory when using, and its opening A11 that is suitable for of easy wrong plug, and cause the storage card front end to be subjected to damaged in collision, when if the less storage card of width inserts than the opening A11 of large space accidentally, easily make the contact of storage card be electric connection with relative terminal group B1 butt, and cause the terminal group B1 bending or the fracture of other different size, and then storage card is died from the insulating base frame A, can't use and cause the entire card connector to damage; Moreover, this kind card connector has been tending towards microminiature, when making,, and then make part opening thickness comparatively thin little because of it has the opening of different in width, comparatively difficult when injection molded, and after long-time plug is used, cause part shedding deformation or wearing and tearing easily, and then reduce the useful life of product, so that the flaw ratio of product own increases, and must increase extra manufacturing cost.

So, how solve the above problems and lack, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
