Patent documentation 1: No. 3924677 communique of Japan Patent
The connector for memory card 100 that possesses above-mentioned wrong insertion preventing mechanism contacts with contact 102a for the conducting strip 12a of the storage card 10 that makes to insert with normal posture, as shown in figure 10, must make to misplug into the height that prevents projection 101 is that it is highly restricted by the height of groove 11.For example, the degree of depth of groove 11 is about 0.5mm, misplugs and prevents that projection 101 from least needing is the height below this height 0.5mm.
On the other hand, card folding and unfolding portion 103 is in order to cover contact 102 and storage card 10, the situation that the cover 104 being consisted of metallic plate elastomeric material above it covers is more, even misplug into storage card 10, can cross and misplug into preventing projection 101 by covering 104 bending, likely can not play and misplug into preventing function.
And, owing to mispluging, prevent that projection 101 need to be configured at the rear of the contact 102 contacting with conducting strip 12a not in the groove 11 with storage card 10 butts, therefore for its direction of insertion, also cannot obtain sufficient thickness, owing to can not get intensity, therefore the storage card 10 and its butt that with mistake posture, insert, easily damaged.
And, need to form accurately small projection 101 at the inner face that forms the housing of card folding and unfolding portion 103, the mould structure of manufacturing housing becomes complicated, requires the strict accuracy of manufacture.
Summary of the invention
The present invention considers this existing problem and completes, its object be to provide a kind of without processing housing, can prevent with simple reliable in structure the connector for memory card of insertion of the storage card of incorrect posture.
In order to achieve the above object, the connector for memory card of the first scheme of the present invention comprises: the housing that a plurality of contact pieces are installed mutually insulated, and cover, above above-mentioned cover covering shell, and and housing between be formed for the card folding and unfolding portion of the storage card that folding and unfolding inserts towards the place ahead from rear, direction of insertion above and between a side, be formed with misplug into prevent with the storage card on inclined plane by folding and unfolding when blocking folding and unfolding portion, above-mentioned each contact contacts with a plurality of conductive parts that expose in the place ahead of storage card, said memory card is characterised in that with the main of connector, on cover, be integrally formed cardinal extremity from the center side of cover towards the direction of intersecting with the direction of insertion of storage card by the plate spring sheet of cantilever support, the at least free end side of plate spring sheet is tilted downwards also as mispluging into preventing board with respect to cover, misplug and prevent that the side, rear of board and the direction of insertion of storage card are orthogonally in card folding and unfolding portion, and cross the motion track on the inclined plane of the storage card that is inserted into card folding and unfolding portion.
With normal posture, insert the inclined plane and the mispluging into the butt below that prevents the side, rear of board of motion track of crossing inclined plane of the storage card of card folding and unfolding portion.Owing to mispluging into the side, rear that prevents board in the direction of the direction of insertion quadrature with storage card towards card folding and unfolding portion, therefore along with storage card insertion forwards, move to free end side with the butt position of storage card, misplug into the integral body that prevents board and be directed into from card folding and unfolding portion and keep out of the way upward, storage card becomes the insertion free state of further forwards inserting.On the other hand, the storage card inserting with incorrect posture due to beyond inclined plane and face direction of insertion quadrature with misplug into the side, rear that prevents board butt substantially in parallel, therefore misplug into the butt position that prevents board and do not move, can not keep out of the way from card folding and unfolding portion, thus storage card further insertion be forwards limited.
In addition, alternative plan of the present invention is characterised in that, covers and is formed by conductive metal plate, will cover otch and become roughly U-shaped, by the part cutting of covering, is erected and is formed plate spring sheet.
By the direction otch intersecting with the direction of insertion of storage card that covers on consisting of conductive metal sheet is become to roughly U-shaped, thereby side forms by the plate spring sheet of cantilever support within it.The free end side of the plate spring sheet of only motion track with inclined plane being intersected is in vertical direction crooked downwards, and also it,, in card folding and unfolding portion, just forms and misplugs into preventing board.
In addition, third party's case of the present invention is characterised in that, misplugs into the front end that prevents board more outstanding towards rear than the rear side of base end side.
Owing to mispluging into preventing that board from tilting with respect to cover downwards, so the side, rear of its front end is rearward more outstanding below than base end side.Even take incorrect posture by direction of insertion above up and down as the storage card of flexure plane inserts, the side, rear of front end at first with the butt above of flexure plane below, it inserts and is not directed into the mispluging into preventing that board from limiting of top.And, if insert the storage card inserting with normal posture, misplug into prevent board side, rear centre at first with the inclined plane butt of storage card, move to free end side butt position, thereby misplug into prevent board body from card folding and unfolding portion keep out of the way upward, storage card becomes the state freely that further forwards inserts.
In addition, cubic case of the present invention is characterised in that, above plate spring sheet, forms from free end and broadens towards cardinal extremity width.
The storage card and side, the rear butt that forwards insert, produced maximum bending moment by the cardinal extremity of the plate spring sheet of cantilever support, but because section factor increases towards cardinal extremity, therefore for the bending to direction of insertion, plate spring sheet is difficult to breakage.
In addition, the 5th scheme of the present invention is characterised in that, misplug prevent board side, rear and below between be formed with downward-sloping guide surface.
Due to the inclined plane of the storage card inserting with normal posture and downward-sloping guide surface butt, therefore will misplug into preventing that board guiding is for keeping out of the way top.The direction of insertion of the storage card inserting with incorrect posture above with parallel in vertical direction side, rear butt, but not with guide surface butt, therefore misplug into preventing that board can not be directed into top.
Effect of the present invention is as follows.
According to the first scheme of the present invention, utilization on cover, be formed with make free end side towards the direction ground intersecting with the direction of insertion of storage card the simple structure to the plate spring sheet in card folding and unfolding portion, can get rid of reliably the insertion of inserting the storage card that blocks folding and unfolding portion with incorrect posture.
In addition, owing to being formed with and having the plate spring sheet mispluging into preventing board on cover, what can form with former case side misplugs into preventing protrusion frames portion use, can prevent more reliably the insertion of mistake posture.
According to alternative plan of the present invention, can not use new parts just to form and there is the plate spring sheet mispluging into preventing board by the cover that forms card folding and unfolding portion.
Because the section factor of the plate spring sheet erecting from cover cutting on the direction of storage card and side, rear butt is large, therefore can with respect to the direction of insertion of storage card, not produce large bending stress, be difficult to breakage.
Cover by shield contact and/or storage card only just can be formed and misplug into preventing board by simple pressure processing.
According to third party's case of the present invention, though the direction of insertion of storage card above be formed with up and down flexure plane, the vertical flat face above of the storage card inserting with incorrect posture with misplug into side, the rear butt that prevents board, limit reliably its insertion.
According to cubic case of the present invention, plate spring sheet does not produce strain, can limit the insertion of the storage card inserting with incorrect posture.
According to the 5th scheme of the present invention, inclined plane and the guide surface butt of the storage card inserting with normal posture, misplug into preventing that board from keeping out of the way from blocking folding and unfolding portion more reliably.

Embodiment
Below, utilize Fig. 1 to Fig. 8 that the connector for memory card 1 of one embodiment of the present invention is described.For the explanation of connector for memory card 1, cover 3 sides of Fig. 2 of take are top, take housing 2 sides as below, and the above-below direction of take in Fig. 3 (a) is fore-and-aft direction, and the left and right directions of take describes as left and right directions.As shown in Figure 2, this connector for memory card 1 comprises: housing 2, and this housing 2 is by the frame section of the コ word shape of the periphery along except rear and form recess in inner side; And the conductive metal cover 3 of assembling above housing 2, metal cap 3 is from the recess of top covering shell 2, thereby between it, forms the card folding and unfolding portion 6 of folding and unfolding storage card 10.
Between the frame section of the left and right of housing 2, set up in contact the discharge plate 13 sliding freely in the front and back of 5 contact site, this discharge plate 13 is rearward afterburning by the Compress Spring 14 being arranged in the correct frame portion of housing 2, and rotate the connecting rod that the heart type cam path in being connected with freely front end and being formed at the correct frame portion in its place ahead coordinates, thereby form known push-push ejecting mechanism.That is to say, the storage card 10 inserting with normal posture and discharge plate 13 butts, if opposing Compress Spring 14 further forwards inserts, connecting rod coordinates with the latched position of heart type cam path, discharge plate 13 and be positioned in latched position, even if storage card 10 is removed insertion force under the state being connected with contact 5, also can be held.And if be further pressed into storage card 10 from this state, connecting rod leaves from the latched position of heart type cam path, storage card 10 utilizes the discharge plate 13 of compressed spring 14 reinforcings and is discharged from from card folding and unfolding portion 6.
Near the opening of the card folding and unfolding portion 6 of more leaning on rear between the frame section of the left and right of housing 2, rotate and set up freely opening-closing plate (シ ャ ッ タ mono-) 15.Opening-closing plate 15 covers near the opening of the card folding and unfolding portion 6 of folding and unfolding storage card 10 not, prevents that dust from entering in card folding and unfolding portion 6.In addition, the structure of the auxiliary section 15a of opening-closing plate 15 is as follows: a pair of V word shape detection lug 16,16 that near the position separated with the left and right in metal cap 3 sides of this auxiliary section of the state 15a opening that covers card folding and unfolding portion 6 forms coordinates, at storage card 10, from the occasion of oblique insertion beyond the direction of insertion of fore-and-aft direction, be limited with not being disengaged coordinating of the V word shape detection lug 16 of a side to rotate, thereby the storage card 10 beyond restriction fore-and-aft direction is to the insertion blocking in folding and unfolding portion 6.
And the height h of the inner bottom surface apart from card folding and unfolding portion 6 of the auxiliary section 15a of opening-closing plate 15 is the height lower a little than the thickness of the storage card 10 of the regulation being connected with connector for memory card 1.Thus, even if will will insert card folding and unfolding portion 6 than the thin storage card of the height of auxiliary section 15a, also a pair of V word shape detection lug 16,16 cannot be pushed to and remove and the coordinating of opening-closing plate 15, restriction is to the insertion of card folding and unfolding portion 6.
As shown in Figure 2, metal cap 3 is that the left and right sides of rectangular-shaped conductive metal plate is bent to the recess that surrounds the left and right frame section of housing 2 from outside and be mounted to covering shell 2, so the rear side cutting in its plane erects outside the V word shape detection lug 16 that forms one side, at the contact 5a than being arranged on housing 2, by the plane at rear, plane is become to roughly U-shaped towards right-hand otch a little, thereby be formed with plate spring sheet 4 in this inner side.At this, roughly U-shaped refers to all shapes that comprise the one side that leaves base end side except V word shape and form elongated, belt-shaped.
As shown in the figure of Fig. 3 (a), figure (b), plate spring sheet 4 take metal cap 3 planes center side as cardinal extremity 4a towards right-hand integratedly by cantilever support, the rear side edge 4b observing from vertical direction is parallel with left and right directions, and with the direction of insertion quadrature of storage card 10.On the other hand, the place ahead side 4c is towards right-hand tilted rearward, and thus, the width of the fore-and-aft direction of plate spring sheet 4 becomes the width (too width) broadening towards base end side from free end, the section factor around neutral axis of vertical direction is increased towards cardinal extremity 4a.As described later, mispluging into preventing that board 8 is subject to the insertion force forwards from storage card 10 of the free end side of plate spring sheet 4, at cardinal extremity 4a, produce maximum bending moment, but because the section factor of cardinal extremity 4a is maximum, can reduce bending stress, even if being therefore subject to stronger insertion force is also difficult to plastic deformation.
In addition, plate spring sheet 4 is oliquely downward crooked near central authorities, and its free end side becomes towards blocking mispluging into preventing board 8 in folding and unfolding portion 6.As shown in the figure in Fig. 4 (a), figure (b), misplug prevent board 8 with cross with normal posture, be inserted into the place ahead the inclined plane 10a of storage card 10 in the mode of the motion track of card folding and unfolding portion 6 interior movements in card folding and unfolding portion 6, thus, as shown in the figure in Fig. 5 (a), figure (b), figure (c), the upper end of the inclined plane 10a of the storage card 10 inserting with normal posture with misplug into the lower end butt that prevents side, the rear 8a of board 8.
Base end side is oliquely downward crooked misplugs position ground that the free end that prevents board 8 is positioned at below to card folding and unfolding portion 6, at this, and free end and to blocking below the height h of auxiliary section 15a that interval between the inner bottom surface of folding and unfolding portion 6 is opening-closing plate 15 at least.Thus, opening-closing plate 15 is rotated and the storage card 10 that inserts and its insertion posture independently with misplug into preventing board 8 butt reliably.
In addition, as shown in the figure in Fig. 6 (a), figure (b), this misplugs into the free-ended rear side 8d that prevents board 8 and forms than side, the rear 8a of its base end side and rearward give prominence to.Therefore, as shown in Fig. 6 (c), even if the top above of the storage card 10 that the incorrect posture of take is inserted is flexure plane, butt before side, the rear 8d that is positioned at below and storage card 10 smooth, storage card 10 can not creep into mistakenly to misplug and into preventing the below of board 8, make to misplug into preventing that board 8 from keeping out of the way upward.
As shown in the figure in Fig. 3 (c), in the present embodiment, due to form along misplug into prevent board 8 side, rear 8a and below the boundary face of 8b to the guide surface 8c of the back lower place, so the inclined plane 8c of the top of inclined plane 10a and 8a bottom, side, rear butt reliably.
In the connector for memory card 1 so forming, first as shown in Figure 1, the occasion that the storage card 10 using inclined plane 10a as the normal posture in bight, right front is inserted to card folding and unfolding portion 6 describes.Even the storage card 10 inserting with normal posture, in direction of insertion, with respect to the direction of insertion of stipulating, be the occasion of fore-and-aft direction inclination and/or the occasion of inserting the thin storage card below regulation with respect to the height of card folding and unfolding portion 6, because at least one side of a pair of V word shape detection lug 16,16 can not pushed to top because of inserted storage card, can not remove with coordinating of opening-closing plate 15, so opening-closing plate 15 does not rotate to cover the state of the opening of card folding and unfolding portion 6.That is to say, the storage card 10 of normal posture roughly inserts the place ahead of card folding and unfolding portion 6 along fore-and-aft direction.
As shown in the figure in Fig. 4 (a), figure (b), storage card 10 is being inserted into and is mispluging when preventing the butt position of board 8, due to misplug prevent board 8 in the mode of motion track of inclined plane 10a of crossing bight, right front in card folding and unfolding portion 6, be therefore positioned at the centre position butt into the bottom that prevents board 8 (guide surface 8c) that misplugs of the height identical with storage card 10 with the height apart from inner bottom surface.As shown in the figure in Fig. 5 (a), figure (b), figure (c), with respect to mispluging, prevent that board 8 is downward-sloping towards right-hand (left in the figure in Fig. 5 (b)), inclined plane 10a is towards right-hand tilted rearward, therefore along with storage card 10 forwards moves, butt position moves to free end side (right-hand) along mispluging into the guide surface 8c that prevents board 8.On the other hand, due to constant with the height apart from inner bottom surface of inclined plane 10a mispluging into preventing board 8 butts, so the height of butt position can not change, and misplugs into preventing that board 8 is brought to the top of keeping out of the way from card folding and unfolding portion 6.
Therefore, can by storage card 10 misplug prevent board 8 below further forwards insert.Now, owing to mispluging into preventing that frame section 7 is located at and the hands-off position of inclined plane 10a that is inserted into the storage card 10 in the place ahead with normal posture, therefore by the groove 11 of storage card 10, storage card 10 is inserted into the link position that each conducting strip 12 contacts with contact 5.Under this state, even if remove insertion force forwards, by above-mentioned push-push ejecting mechanism, storage card remains on this link position.
Discharge the occasion of storage card 10 from card folding and unfolding portion 6, if further push storage card 10 from link position, storage card 10 utilizes the discharge plate 13 of rearward reinforcing of compressed spring 14 to be discharged from from card folding and unfolding portion 6.Because the V word shape detection lug 16 mispluging into preventing board 8 and a side consists of flexure strip respectively, therefore because storage card 10 is discharged from, thereby reset to position before insertion, towards the position in card folding and unfolding portion 6, a side V word shape detection lug 16 coordinates with the auxiliary section 15a of opening-closing plate 15 respectively.
Next, the occasion that the card folding and unfolding portion 6 of subtend connector for memory card 1 inserts the storage card 10 of putting upside down the mistake posture in table or using inclined plane 10a as rear describes.Even the storage card 10 of this mistake posture, because its thickness is identical, if insert along fore-and-aft direction, the cooperation of opening-closing plate 15 is disengaged, and can insert to the place ahead of card folding and unfolding portion 6.
The storage card 10 of the mistake posture that opening-closing plate 15 is rotated and forwards insert is not having inclined plane 10a into the position that prevents board 8 butts with mispluging, become top crooked and with the continuous smooth vertical plane 10b of upper surface.On the other hand, mispluging in card folding and unfolding portion 6, prevent in board 8, because 8dXiang rear, side, free-ended rear is side-prominent, therefore as the figure in Fig. 6 (a), figure (b), shown in figure (c), misplug into preventing the free end of below of board 8 and the smooth vertical plane 10b butt of storage card 10.Therefore, the flexure plane of vertical plane 10b top with misplug into the base end side bottom butt that prevents board 8, misplug into preventing that board 8 from can not boosted upward.
Owing to the vertical plane 10b of storage card 10 mispluging into preventing the free end butt of board 8 being and the tabular surface of direction of insertion quadrature, butt position can not moved, and misplugs into preventing that board 8 from can not keep out of the way upward from card folding and unfolding portion 6.Therefore, the further insertion forwards of the storage card 10 of mistake posture is mispluged into preventing board 8 restrictions, can not be inserted into the link position that each conducting strip 12 contacts with contact 5.
With misplug into the front and back that prevent board 8 butts, because the storage card 10 that will forwards insert does not have inclined plane 10a mispluging on the position that prevents frame section 7, as shown in Figure 7, and misplug into preventing frame section 7 butts, its insertion is restricted.That is to say, as shown in the drawing, with mispluging into preventing board 8 and mispluging into preventing any of frame section 7 or the insertion to link position of the storage card 10 that both restrictions are inserted with incorrect posture.Be inserted into the storage card 10 of this position owing to not reaching link position, if therefore remove insertion force, by the discharge plate 13 of rearward reinforcing of compressed spring 14, from card folding and unfolding portion 6, discharged.Because the V word shape detection lug 16 mispluging into preventing board 8 and a side consists of flexure strip respectively, therefore because storage card 10 is discharged from, return to original position before insertion, towards the position in card folding and unfolding portion 6, a side V word shape detection lug 16 coordinates with the auxiliary section 15a of opening-closing plate 15 respectively.
In the present embodiment, misplug into preventing that frame section 7 from also having limited the insertion of storage card 10, if but only with mispluging into preventing that board 8 from can limit, not necessarily must arrange.
In addition, although making the 8dXiang rear, side, free-ended rear mispluging into preventing board 8 gives prominence to, if but storage card is not form the tabular storage card of flexure plane above the storage card inserting with incorrect posture, also can make until the plane of free end and direction of insertion quadrature mispluging into side, the rear 8a that prevents board 8.
In addition, in the present embodiment, to the insertion posture of conducting strip 12 storage card 10 that expose in the place ahead of side is below illustrated as normal posture, but also can be using the insertion posture of the storage card 10 inserting on the contrary in table as normal posture.In this occasion, due to bight, 10aWei left front, inclined plane, so plate spring sheet 4 from cover 3 central authorities towards left by cantilever support.
