Description
Technical field
The utility model relates to card connector, particularly a kind of can compatible multiple storage card, volume is little, and under any circumstance only allow the misplug prevention device of the three-in-one card connector that a card inserts.
Background technology
At present the flash memory that uses is called for short storage card, purposes more and more widely, especially to single, independent or temporary data storing, the big capacity setting that can exempt main storage.Simultaneously, by the use to this monomer shape of storage card memory, the storage and the file administration that can be particular data bring great convenience.Consumer electronics product particularly, such as mobile phone, digital camera, digital camera MP3 player or personal digital aid (PDA) (PDA) etc., the storage card that is adopted, on the whole can be divided into multimedia card (Multi-Media Card, be called for short mmc card), save digital card (Secure Digital Card from damage, be called for short the SD card), dexterous media card (SmartMedia Card is called for short the SM card), quickflashing microstorage card (Compact Flash Card, comprise Type I and Type II, be called for short the CF card), store 20 card (Memory Stick, be called for short the MS card), and be that the series storage card that design obtains is improved on the basis with them, as MICRO SD card.
Electronic products such as mobile phone now, digital camera, function from strength to strength on the one hand, requirement to the data memory space is also increasing, on the other hand, on the volume but all towards light, thin, short, little development, therefore, on the basis of existing single card connector, increase a plurality of multiple storage card slots and jockey, just become very meaningful.Card connector generally is directly to be installed on the circuit board, for the various storage card of planting, the interior data of card can be electrically connected via this card connector with circuit board.But under a lot of situations, some main control devices as computer, can only be discerned a storage card and carry out read-write operation at synchronization, and if in two slots of many card connectors plug-in card simultaneously, then may cause infringement to storage card; So just require connector that reliable misplug prevention device is provided.Existing many card connectors reasonably do not address this problem as yet.
The utility model content
At the existing above-mentioned deficiency of existing multi-memory card connector, the purpose of this utility model is, provide a kind of be provided with three slots and three groups of splicing ears, simultaneously compatible multiple storage card, volume little, and under any circumstance only allow the misplug prevention device of the three-in-one card connector that a card inserts.
The technical scheme that the utility model adopted is: a kind of misplug prevention device of three-in-one card connector, comprise the metal cap body that microscler pedestal and that an insulating material is made is interlocked with it, the openend of described pedestal two side inwardly forms three slots that are used for ccontaining different storing card respectively, the size moulding of described each slot is corresponding a kind of storage card respectively, its posterior segment is a big slot, and leading portion is two little slots that separate about a dividing plate; On the relevant position of this pedestal in each slot, respectively be provided with one group of terminal groove, respectively be embedded with a splicing ear group corresponding in the groove with the storage card pin; It is characterized in that: on the two side of described pedestal leading portion and on the dividing plate, laterally have a groove along same straight line; In described three grooves, being provided with one can be along the last fool proof post of its lateral shaft rotation, and being provided with one on the dividing plate in the set groove can be along the following fool proof post of its radial axle rotation; The described fool proof post of going up is the cylindrical component that corresponding two little slot positions are provided with two sections triangle cones, and corresponding biside plate groove in its two ends and middle part and partition groove respectively are provided with one section rotating shaft, and described rotating shaft all snaps in its corresponding end pilot trench; Describedly go up the set rotating shaft in fool proof post two ends, its outside also is provided with one section semicylinder, and the set projection of fit makes the described fool proof post of going up can only half-twist; Described fool proof post down is that a bottom is provided with a circular shaft, the cross section is fan-shaped cylinder, and it snaps in the set groove of dividing plate, and its underpart cylinder inserts in the set corresponding axis hole of pedestal, and top is blocked by the described fool proof post of going up; Described lid is by being that a top board and biside plate are formed
The hardware of shape, corresponding described biside plate groove location respectively is provided with a spacer on its top board, and this spacer is stuck in described rotating shaft of going up fool proof post two ends in the groove behind described lid and pedestal fastening; When having storage card to insert in the described big slot, the card body promotes the described fool proof post of going up and rotates, one side the part socket of described two little slots is blocked in moving down of its conical surface, makes this two little slot can't insert storage card again; Otherwise when any one had storage card to insert in the described two little slots, the card body promoted the described fool proof post of going up and rotates, and moves on one side of its conical surface, blocks the part socket of described big slot, makes this slot can't insert storage card again; Simultaneously, when any one had storage card to insert in the two little slots, the card body also promoted described fool proof post down and rotates, one side the part socket of described another little slot is blocked in moving to left or moving to right of its covering of the fan, makes this little slot can't insert another storage card again.
On the described pedestal, corresponding described three splicing ear groups also respectively are provided with a detection terminal that is used for detection of stored card position signal; On the described lid, also corresponding each detection terminal is respectively equipped with a metal and connects shell fragment; When not having storage card to insert, the two is often opened; When storage card inserted slot, the card body promoted detection terminal and is connected shell fragment contact and electric connection with metal.
The described fool proof post of going up, it is provided with chamfering on a side of described slot socket; Described fool proof post down, its fan-shaped center also is provided with chamfering on a side of described slot socket.
The terminal of described each terminal group is the arc flexible terminal that arches upward to the inside, and its anterior contact jaw is to protrude in base plate, and the welding ends of its afterbody is to pass pedestal and stretch out in outside the base plate; The welding ends of the terminal of each terminal group is welded on the printed circuit board (PCB).
