Abstract

The utility model relates to a memory card connector. The utility model comprises a seat body, a first memory card slot and a second memory card slot. The first memory card slot and the second memory card slot are respectively used to splice a first memory card and a second memory card, and the first memory card slot and the second memory card slot are arranged on the adjacent side surface of the memory card connector. After the first memory card is fully inserted into the first memory card slot, the vertical distance from the front end of the first memory card to the far end of the second memory card slot is smaller than the width of a second memory card main body. The technical proposal of the utility model can effectively avoid the hardware and controlling software conflict brought about by inserting a plurality of memory cards at the same time, in addition, the structure is simple and the realization is easy.

Description

Memory card connector

[technical field]

The utility model relates to a kind of memory card device, particularly a kind of memory card connector that prevents that a plurality of memory cards from inserting simultaneously.

[background technology]

At present, electronic products such as digital camera, mobile phone can adopt memory card (Memory Card) to come data on file usually, so that preserve or transferring data.Therefore, a memory card slot generally can be set, in order to the corresponding memory card of pegging graft on above-mentioned electronic product.And when the data of preserving need be transferred on the equipment that computer etc. has strong data processing or memory function, except that directly connecting electronic product the computer by connecting line, memory card can also be taken out, put into special memory card connector (Connector) or card reader (Card Reader) and carry out data and read.

Because existing memory card is of a great variety on the market, comprise SM (Smart Media) card, CF (Compact Flash) card, MMC (Multi Media Card) card, SD (Secure Digital) card, memory stick (Memory Stick), XD (XD-Picture) card etc., its performance is different, and volume is not of uniform size.General memory card connector only can provide the memory card of a kind of slot of size with the corresponding size of pegging graft, and the memory card that the user has then may have different sizes, thereby it is standby to need to buy a plurality of connectors, causes and uses inconvenience.

Provide a kind of memory card dual slot adapter that addresses the above problem in No. the 02291211.8th, Chinese patent application, this adapter housing front end is provided with adapter card end, and its housing rear end is provided with U type slot, is provided with a memory card connector in this U type slot; The left side of this housing or right edge are provided with an opening, be provided with second memory card connector in the housing corresponding to this opening: the memory card of can peg graft respectively CF and MS, SD, plurality of specifications such as MMC, SM, therefore, can be common to the memory card of grafting plurality of specifications, satisfy different consumers' use needs.But after a connector of this device was inserted into memory card, another connector still can insert memory card, and may cause the conflict on the hardware and be that the user brings unnecessary trouble this moment.

[utility model content]

Technical problem to be solved in the utility model is to provide a kind of memory card device, particularly a kind of memory card connector that prevents that a plurality of memory cards from inserting simultaneously.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of memory card connector, it comprises a pedestal, one first memory card slot and one second memory card slot, described first memory card slot and one second memory card slot are respectively applied for peg graft first memory card and second memory card, this the first memory card slot and the second memory card slot are arranged at the adjacent side of memory card connector, after this first memory card inserts the first memory card slot fully, the vertical range of its front end to the second memory card slot far-end is less than the width of this second memory card body.

The technical solution of the utility model can effectively be avoided inserting hardware and the Control Software conflict that a plurality of memory cards bring simultaneously, and simple in structure, realizes easily.

[embodiment]

The utility model will be further described below in conjunction with accompanying drawing.

See also Fig. 1, memory card connector 1 of the present utility model comprises a pedestal, and offers thereon the first memory card slot 20 and the second memory card slot 40.In the present embodiment, this first memory card slot 20 is arranged at memory card connector 1 downside, and this second memory card slot 40 is arranged at memory card connector 1 left side, also can it be arranged at other not ipsilateral according to demand, only need guarantee to get final product into adjacent side.

Wherein, this first memory card slot 20 be used to peg graft a kind of memory card 22 of specification, in the present embodiment, memory card of be used to peg graft CF card, MS, SD, MMC, MS Duo (Memory Stick Duo) card (10pin) size.This second memory card slot 40 be used to peg graft memory card 42 of another kind of specification, in the present embodiment, the memory card of MS Micro (11pin) size that is used to peg graft comprises T-FLASH (8pin), MMC Micro card (10pin), Mini SD card (11pin) etc.

See also Fig. 2 A to Fig. 2 C, below how explanation memory card connector 1 of the present utility model avoids two slots to insert memory card simultaneously.Structurally, the first memory card slot 20 and the second memory card slot 40 are arranged at the adjacent side of memory card connector 1, and the second memory card slot 40 is set to, the vertical range a of its front end to the first memory card slot 20 far-ends after memory card 42 inserts fully is less than the width b of memory card 22 bodies.In the present embodiment, a is 16 millimeters, and b is 20 millimeters.At this moment, after inserting memory card 22, because the space of the second memory card slot 40 partly occupied, so can't insert small size memory card 42 again; In like manner as can be known, after inserting small size memory card 42, also can't insert large scale memory card 22 again.Therefore, avoided inserting simultaneously hardware and the Control Software conflict that two memory cards bring effectively.

See also Fig. 3, memory card connector 1 of the present utility model connects a card reader 60, and above-mentioned two memory card slots are electrically connected on this card reader 60.As card reader 60 is arranged at computer inside, then this card reader 60 can be the part of computer internal circuit; As being made as card reader 60 external, then can pass through USB (Universal Serial Bus, USB) connecting line or IEEE (Institute of Electrical andElectronics Engineers, institute of electrical and electronic engineers) 1394 connecting lines are connected to computer with card reader 60.

Certainly, memory card connector 1 also can be the integral type design with card reader 60.Shown in Fig. 4 A to Fig. 4 B, memory card connector 1 has been adorned and has been sent out in card reader 60 inside.Locate when large scale memory card 22 inserts, small size memory card 42 can't insert the location, and then the IC of card reader 60 has only detected memory card 22 insertions, does not have memory card 42; Locate when small size memory card 42 inserts, large scale memory card 22 can't insert the location, and then the IC of card reader 60 has only detected memory card 42 insertions, does not have memory card 22.
