Description

The All-in-One card connector

[technical field]

The utility model relates to a kind of electronic card coupler, refers in particular to a kind of All-in-One electronic card coupler of the different electronic cards of pegging graft.

[background technology]

Flash memory is just strong because of calculation function, charming characteristics such as speed is fast, expandability is high, high storage density since coming out, because flash memory has above all multi-functional and characteristics, just have relevant dealer to utilize flash memory and develop all types of electronic cards, as the electronic cards of specifications such as mmc card, SD card, MS card, CF card, XD card.Existing many digital consumer products as mobile phone, digital camera, camcorder, and PDA etc., have had more and more stronger dependence to this type of electronic cards; In addition, 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, make that electronic cards will be used to directly replace traditional Storage Medias such as the rigid disk utmost point by this in the products such as mobile computer, desktop PC and auto electronic class.Because the electronic cards development of advancing by leaps and bounds, thus relatively its employed card connector also with increase in demand.

General card connector comprises the insulating body of accommodating plurality of conductive terminals and installs shielding casing on insulating body, this insulating body and shielding casing are built into the receiving space of accommodating electronic cards jointly, insert by electronic cards and reach the purpose that electronic cards and card connector electrically contact in the receiving space.Because of the specification difference of various electronic cards, its apparent size and shape are also variant, and the electronic cards of different size must be plugged in the particular form card connector that is complementary with its external form, to realize electrically conducting of electronic cards and card connector.Therefore, must be provided with multiple multi-form card connector in circuit board, to reach the purpose that matches with different electronic cards.Yet this mode makes card connector take the mainboard space to be increased, and then causes the electronic equipment volume to increase, and is unfavorable for electronics miniaturization.

Therefore, just have the dealer to design a kind of All-in-One card connector of the multiple different size electronic cards of pegging graft, it takes up room little and uses more convenient.Xiang Guan prior art can be consulted Chinese utility model and announced shown in No. 2687868 patent the 5th figure therewith, the All-in-One card connector that it disclosed mainly comprises shielding casing 1, insulating body 2 and terminal module 3, wherein the roof 23 of insulating body 2 is provided with first support slot 2323 and second support slot 2324 that is " protruding " shape, the installation portion of long first conducting terminal 32 that terminal module 3 is settled is immobilizated in respectively in first support slot 2323 and second support slot 2324, the installation portion of the second short conducting terminal 33 is immobilizated in first support slot 2323, by these support slots first conducting terminal 32 and second conducting terminal 33 is fixed in the roof 23 of insulating body 2.

But, during the assembling of this kind All-in-One card connector, because first conducting terminal 32 that is contained in the terminal module 3 is long than second conducting terminal 33, therefore first conducting terminal 32 passes first support slot 2323 earlier, further this terminal module 3 is inserted, first conducting terminal, 32 correspondences are passed second support slot 2324 of being located at first support slot, 2323 front ends, and second conducting terminal 33 passes first support slot 2323 simultaneously.Because conducting terminal is longer than first conducting terminal 32 in thin and this kind execution mode, this first conducting terminal 32 need pass first support slot 2323 and second support slot 2324 successively again, easily causes first conducting terminal 32 to be lost during insertion; In addition, corresponding respectively insertion of these conducting terminals is located at being in " protruding " shape support slot on insulating body 2 roofs, practical operation is more loaded down with trivial details, and the top of insulating body need be provided with these support slots, has strengthened the Mold Making difficulty.
