Description

Three-in-one card connector

Technical field

The utility model relates to a kind of card connector, especially relates to a kind of three-in-one card connector.

Background technology

Flash memory is just strong because of calculation function, characteristics such as speed is fast, expandability is high, high storage density since coming out; Because flash memory has above many functions and characteristic; Just have relevant dealer to utilize flash memory and develop all types of electronic cards, like the electronic cards of specifications such as mmc card, SD card, SIM, MS card, CF card, XD card.Existing many digital consumer products, platform mobile phone, digital camera, DV 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, because the development that electronic cards is advanced by leaps and bounds, its employed card connector is also with increase in demand relatively.

General card connector comprises the insulating body of accommodating plurality of conductive terminals and installs the shielding casing on insulating body; Change insulating body and shielding casing and build up the receiving space of accommodating electronic cards jointly, insert through electronic cards and reach the purpose that electronic cards and card connector electrically contact in the receiving space.Because of the specification of various electronic cards is different, its apparent size and shape clothing are variant, and the electronic cards of different size must be plugged in the particular form card connector that is complementary with 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 the different electric subcard; 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 can to peg graft the All-in-One card connector of multiple different size electronic cards, it takes up room little and easy to use.This type of All-in-One card connector generally is different terminal group to be set electrically connect to form with different cards in a plurality of accepting grooves.

But this type of card connector in use, and electronic cards floats easily, electrically connects unstable; And inconvenient when extracting electronic cards, influence useful life of card connector easily.

The utility model content

The purpose of the utility model is to overcome deficiency of the prior art, provides a kind of electric connection stable and long service life card connector.

For reaching above-mentioned purpose, the utility model comprises first insulating body, second insulating body, plurality of terminals group and housing, offers first accepting groove on first insulating body; Said first accepting groove is provided with card; Second insulating body is arranged on first insulating body, forms second accepting groove between second insulating body and first insulating body, is provided with pallet in said second accepting groove; Said pallet can slide front and back; Offer the 3rd accepting groove on second insulating body, terminal group is contained in first accepting groove, second accepting groove and the 3rd tank, and housing is covered on second insulating body.

Further, said card comprises the plurality of fixed pin, offers some draw-in grooves on said first insulating body, and said fixing feet snaps in the draw-in groove.

Further, said pallet comprises disk body, and the two side ends of disk body bends and extends into a pair of lateral body; Said first insulating body comprises pair of sidewalls, offers chute on the sidewall, and said lateral body movably is contained in the chute.

Further, said card is a metal material.

Further, the front end of said pallet is provided with block piece.

In sum, the utility model can effectively prevent to be inserted in the electronic cards come-up in first accepting groove through on first accepting groove, card being set, and forms stable electric connection; In second accepting groove, pallet is set, can plugs the electronic cards that is inserted in second accepting groove easily, increase the useful life of card connector.

Embodiment

For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

See also Fig. 1 and Fig. 2, the three-in-one card connector of the utility model comprises first insulating body 10, second insulating body 20, plurality of terminals group, housing 30, card 40 and pallet 50.Second insulating body 20 is arranged on first insulating body 10, and housing 30 is covered on second insulating body 20.Terminal group comprises the first terminal group 61, second terminal group 62 and the 3rd terminal group 63.

Offer first accepting groove 11 on first insulating body 10, the first terminal group 61 is contained in first accepting groove 11; Go between second insulating body 20 and first insulating body 10 and be contained in second accepting groove 12 into second accepting groove, 12, the second terminal group 62; Offering the 3rd accepting groove 21, the three terminal group 63 on second insulating body 20 is contained in the 3rd accepting groove 21.

See also Fig. 2 and Fig. 3, first accepting groove 11 is provided with card 40, and card 40 is a metal material.Card 40 comprises on plurality of fixed pin 41, the first insulating bodies 10 and offers some draw-in grooves 13 that said fixing feet 41 snaps in the draw-in groove 13, thereby card 40 is fixed on first insulating body 10.

See also Fig. 2 and Fig. 4, be provided with pallet 50 in second accepting groove 12, pallet 50 comprises disk body 51, and the two side ends of disk body 51 bends and extends into a pair of lateral body 52; First insulating body 10 comprises pair of sidewalls 14, offers chute 141 on the sidewall 14, and said lateral body 52 movably is contained in the chute 141, thereby pallet 50 can slide along sidewall 14 front and back.The front end of pallet 50 is provided with block piece 53, in order to the localized electron card, for push-and-pull pallet 50 impetus is provided simultaneously.
