Description

The combined type card connector

Technical field

The relevant a kind of combined type card connector of the utility model refers to a kind of connector that multiple memory card is shared that is fit to especially.

Prior art

Employed now memory card is of a great variety, comprise: Smart Media Card (SM card), Memory Stick Card (MS card), SD card and XD card (XD-Picture Card) etc., early stage only at the set connector of single memory card, be difficult to be useful in simultaneously on the diversified now memory card.

The connector that can be suitable for multiple memory card at present simultaneously mainly is provided with a centre pedestal, and the upper and lower circuit board structure that is combined in this centre pedestal upper and lower surface respectively, and the common grafting conduit that forms multiple memory card that cooperates, and weld relevant memory card conducting terminal respectively, and design conversion terminal in addition, cause make and assembling on very bother and expend man-hour, the cost of whole connector also improves relatively, more because of adopting the assembling structure than multicompartment, its accuracy is also undesirable simultaneously.

And the shared connector of card more than this kind is installed on electronic equipment internal, select single plug-in card to use for various memory cards, but behind the various memory card plug-in cards, its front-end edge protruded length has nothing in common with each other, and gap is very big, cause plug-in card and take out on the card inconvenient, and when its protruded length is long, then memory card is damaged by collision easily, is necessary further improvement.

The utility model content

The purpose of this utility model is promptly providing a kind of combined type card connector, it is fit to various different size memory cards and uses jointly, and behind the various memory card plug-in cards, its front-end edge protruded length is roughly the same, make things convenient for plug-in card and take out the card use, and assembling production rapidly, reduces cost, and improves accuracy.

For achieving the above object, the utility model connector insulating body comprises integrated open antetheca, rear wall, left and right sides sidewall, roof and diapire, with empty boxes body in the common formation one, the wideest first card slot of overlapping in regular turn common setting, middle second card slot and the narrowest the 3rd card slot between left and right sides sidewall and roof, diapire, and roof, diapire and the rear wall groove in a row of insulating body respectively toward interior plant be positioned to ranked first, two, three conducting terminals, selective insertion connects first, second or the 3rd memory card; Above-mentioned first, second and third card slot is made as the different length of inserting, make first, second and third memory card plug-in card after, its front-end edge protruded length is roughly the same.

In possible embodiments, this second card slot leading portion and the first card slot intersection are provided with the 4th card slot, and are positioned to ranked fourth conducting terminal toward interior plant, make the 4th memory card plug-in card after, its front-end edge becomes above-mentioned same protruded length.

Embodiment

Novelty of the present utility model and other characteristics will be tending towards clear in cooperating the following drawings and DETAILED DESCRIPTION OF THE PREFERRED.

At first, see also Fig. 1,4,5, the utility model connector can be assembled on the circuit board of electronic equipment, whole insulating body 10 can be one-body molded with insulating material, it comprise open shape antetheca 101, relative with antetheca 101 after wall 102, left and right sides sidewall 103,104, roof 105 and diapires 106, with empty boxes body shape in the common formation one, the wideest first card slot 11 of overlapping in regular turn common setting, middle second card slot 12 and the narrowest the 3rd card slot 13 between left and right sides sidewall 103,104 and roof 105, diapire 106.In a preferred embodiment, more can increase by middle the 4th card slot 14.

First card slot 11 forms the maximum conduit of a width between rear wall 102, left and right sides sidewall 103,104 and roof 105, for the first memory card SM card of planting.The second, 12,14 of four card slots form the intermediate width conduit with the terrace a little less than first card slot 11, for second, four memory card SD cards, the XD card planted.The 3rd card slot 13 then forms conduit with littler width, for the 3rd memory card MS card of planting.In illustrated embodiment, first card slot, 11 bottom surfaces vertically are connected formation the 3rd card slot 13 at the reduced width opening part, and the length of the 3rd card slot 13 is greater than first card slot 11.Second card slot 12 is formed at the leading portion intersection of first and

third card slot

11,13, the 4th card slot 14 then is located at second card slot, 12 leading portions and first card slot, 11 intersections, therefrom can be under the confined space volume one-body molded joint conduit that goes out multiple memory card.Especially first, second, third and

fourth card slot

11,12,13,14 is made as the different length of inserting, make first, second, third and fourth memory card plug-in card after, its front-end edge protruded length is roughly the same, and is perhaps identical, to make things convenient for plug-in card and to take out card use.

Shown in Fig. 1～6, roof 105 back segments, diapire 106 back segments, rear wall 102 and diapire 106 front-end positions at insulating body 10, default separately microscler groove 111,121,131,141 and end vias thereof in a row, the past respectively interior plant of confession is positioned to ranked first, two, three, four conducting

terminals

20,30,40,50, connects first, second, third and fourth memory card SM card, SD card, MS card and the contact of XD card own with cooperation.And first, second, third and fourth conducting

terminal

20,30,40,50 is respectively equipped with and tiltedly sticks up contact-segment and

pin portion

21,31,41,51, and this type of

pin portion

21,31,41,51 stretches out all outward, and can be set as down that folding is flat stretches state, with the contact circuit plate.Simultaneously write-protect control terminal 22 can be set and prevent to misplug shell fragment 23, to cooperate the first memory card SM card at first card slot 11 and first conducting terminal, 20 1 sides.Second card slot 12 and second conducting terminal, 30 1 sides then are provided with write-protect control terminal 32 and plug-in card detecting terminal 33.

The utility model is under first, second, third and

fourth card slot

11,12,13,14 and first, second, third and fourth conducting

terminal

20,30,40,50 combining structures, conducting bottom surface first memory card 61 up of can selecting to peg graft is consulted Fig. 7,8 SM card, second memory card 62 is consulted Fig. 9,10SD card, the 3rd memory card 63 is consulted Figure 11,12MS card, and the 4th memory card 64 is consulted the 13rd, 14 figure XD cards.And behind first, second, third and

fourth memory card

61,62,63,64 plug-in cards, L is identical for its front-end edge protruded length, to make things convenient for plug-in card and to take out card and use.

Because the utility model connector insulating body partly can be with single-piece mode one ejection formation, and first, second, third and fourth conducting terminal of assembling of directly pegging graft, therefore no matter make or assemble all more quick and convenient, whole cost significantly reduces, and structural precision more improves.Especially being fit to various different size memory cards uses jointly, and behind the various memory card plug-in cards, its front-end edge protruded length is roughly the same, makes things convenient for actual plug-in card and takes out the card use, show the unprecedented innovation of genus for existing this type of memory card connector, and have industrial value.

Above illustrated embodiment is only used the utility model for convenience of description, is not in a limitative way, and not from the utility model spirit category, various simple and easy distortion and modification that those skilled in the art made all must include in the scope of claim.
