Technical field
The storage card that the present invention relates to be contained in the accommodation section is connected to the connector for memory card on the electronic equipment; In more detail; Relate in housing body and rotate and freely be supported between the cover on the housing body, storage card is positioned at the connector for memory card in the card accommodation section.
Background technology
Now; Following connector for memory card is arranged as everyone knows: open rotate cover freely and storage card be contained in the card accommodation section of housing body with respect to housing body after; The mode that is contained in the upper surface of the storage card in the card accommodation section with covering is closed cover, and the rotation of limit cover in off position.For the storage card that is contained in the card accommodation section; Contact from housing body towards the card accommodation section is electrically connected with the conductive spacer of storage card bottom surface; And be positioned between blocked cover and the housing body with this state; Therefore; During being electrically connected, do not exist to make storage card vibration because of carelessness or from the card accommodation section, deviate from.
In the connector for memory card of this structure; In order to insert storage card; Making the cover of closing with the mode of the upper surface that covers storage card is to rotate freely that the enable possition slides into the latched position to housing body from cover with respect to housing body, and the rotation of the cover of closing in latched position is limited (patent documentation 1: TOHKEMY 2008-287919 communique).
Figure 12 to Figure 14 representes the connector for memory card 100 of the structure that this cover slides; It is made up of housing body 103 and knuckle guard 106; This housing body 103 is made up of insulating resin; Through erectting side frame 101 is set, thereby is formed with the card accommodation section 103a that a plurality of contacts 102 are faced betwixt along dual-side; This knuckle guard 106 is outstanding to be provided with the pivot 105 in the dead eye 104 that the place ahead (right-hand in Figure 14) of being inserted in side frame 101 wears, and can rotate around pivot 105.
It is the elongated slot 104b of long side direction that the place ahead of dead eye 104 forms with the fore-and-aft direction; Its rear side forms the profile of the keyhole of circular 104a; On the other hand; As shown in figure 14; The profile that inserts the cross section of the pivot 105 in the dead eye 104 is the oblong shape that embeds with a gap among the elongated slot 104b, and the width of its long side direction is the length shorter slightly than the diameter of circular 104a.Therefore; When knuckle guard 106 is positioned at the enable possition (Figure 13) of the rear position of dead eye 104 at pivot 105; Can freely rotate with respect to housing body 103; Pivot 105 can move in elongated slot 104a with the posture of the knuckle guard 106 of the upper surface of closing covering shell main body 103; Therefore, pivot 105 can freely slide into the latched position (Figure 14) of the anterior position that is positioned at dead eye 104.
On the side frame 101 of housing body 103, the top locking accessory 107 that is shaped integratedly with housing body 103 lateral surface of frame 101 from the side is outstanding.The two sides of knuckle guard 106 are the faces along the lateral surface slip of this side frame 101, and are formed with the bottom locking plate 108 that forwards forms L word shape.As shown in figure 13, bottom locking plate 108 is formed on: when knuckle guard 106 is in freely enable possition of rotation, be positioned at the rear of top locking accessory 107, and when being in the latched position that slides into the place ahead, the position that engages with the below of top locking accessory 107.
Under situation about storage card 110 being installed on this connector for memory card 100; As shown in figure 12; Storage card 110 is inserted among the back square frame 106a of portion of the knuckle guard of opening the enable possition 106 and temporary transient the maintenance; As shown in figure 13; Knuckle guard 106 is turned to level, and close with the mode of the upper surface of covering shell main body 102.
Under this state; Because the direction of the pivot 105 of knuckle guard 106 and elongated slot 104b is consistent and can move at fore-and-aft direction; Therefore, knuckle guard 106 is forwards slided, thereby make pivot 105 move to latched position shown in Figure 14 into the front position of dead eye 104.If knuckle guard 106 is forwards slided, then bottom locking plate 108 moves to the below of top locking accessory 107, in both engagings of latched position, thus the rotation of restriction knuckle guard 106.In latched position, be electrically connected with the conductive spacer Elastic Contact with the corresponding contact 102 of each conductive spacer of clamping, locate and be supported on the storage card 110 in the 103a of card accommodation section by knuckle guard 106 with housing body 103.
Under the situation of extracting storage card 110, opposite with said sequence, make knuckle guard 106 rearward slide into the enable possition, thus hinge-opening cover 106 and taking-up card storage card 110.
Said memory card with connector 100 in; For bottom locking plate 108 being slided in the horizontal direction and engaging with the lower surface of top locking accessory 107; Making dead eye 104 rears is that circular 104a, the place ahead are the profile of the keyhole of elongated slot 104b; Thereby can slide with the state of closing knuckle guard 106; But because at elongated slot 104b and be gapped between the pivot 105 of flat posture; Therefore; Even knuckle guard 106 is the postures that tilt a little from horizontal direction, also can slide into latched position from the enable possition.
Knuckle guard 106 with this faulty operation under the situation that latched position moves; Because bottom locking plate 108 is above top locking accessory 107, both are engaging not, therefore; If want to top hinge-opening cover 106 by the strong hand, pivot 105 or elongated slot 104b might be damaged.In addition, if want to close and locking hinge cover 106 by the strong hand, then bottom locking plate 108 is from top and top locking accessory 107 butts, and any one of bottom locking plate 108 or top locking accessory 107 all might be damaged.
Therefore; Different with the plastic housing body of insulating properties 103, top is locked accessory 107 process to be difficult to damaged metallic plate, but because top locking accessory 107 protrudes in the side of side frame 101; Therefore, operator's finger etc. possibly touched and become injured reason.
In addition, the intensity of pivot 105 in order to obtain to stipulate need make the length of the short side direction of longitudinal section be necessarily above length, is oblong shape owing to make the profile in cross section, and therefore, the length of long side direction also need be according to the length lengthening of short side direction.Its result, the internal diameter of the circular 104a of dead eye 104 has enlarged with respect to the pivot of circular cross-section, thereby becomes the obstacle of the height slimming that makes connector for memory card 100.
Summary of the invention
The present invention considers existing these problems and accomplishes that even its purpose is to provide a kind of misoperation of carrying out, the sticking department of the rotation of the rotational support portion of pivot and dead eye and restriction cover can damaged connector for memory card yet.
In addition, its purpose is to provide a kind of width longitudinally of dead eye, connector for memory card of realization slimming of dwindling.
In order to achieve the above object, the present invention is a program 1 memory card connector, comprising: a housing body, along the side edges is formed between the upstanding side frames for accommodating a memory card card receiving portion, the side the rack via the card accommodating portion and the corresponding parts in the horizontal direction is formed in the longitudinal direction of the circular shape of the length of the bearing hole; and a cover, which pivots through said bearing bore, and the cover in the horizontal pivot axis of the bearing bore side in the direction of the open position and a locked position in between the other side, across the card receiving portion to slide freely along the side frames; cover in the open position can be freely pivotally supported on the housing body, in the locked position, the lower part of the cover locking portion formed on an upper surface of an upper side of the chassis locking portion abuts the lower surface, thereby limiting rotation of the body relative to the housing, the memory card connector characterized in that the main, side frames pivot bearing hole is formed on one side in the horizontal direction and the other side either side of the contour are free to rotate, the upper locking portion is not rotated with the cover in the open position the lower locking portion interfering , along and across the card receiving portion slide from the open position to the locked position locking the lower cover portion is formed on the side movement locus of the rack, and, in the locked position, the upper locking portion abuts against the lower parts of the lock from the top of the upper surface of the locking portion abuts against the upper surface of the lower to the upper locking portion of the lower surface of the guide inclined surface.
Because dead eye forms the profile that a pivot side and the either side in the opposite side in the horizontal direction all can freely rotate; Therefore; Even in latched position; Cover also can freely rotate around pivot with respect to housing body; Even open the direction rotating operation slide into because of misoperation the bottom sticking department be positioned at the upper lock bonding part above the cover of latched position, pivot and dead eye do not bear load yet.
In addition; If by the strong hand the closing direction rotating operation slide into because of misoperation the bottom sticking department be positioned at the upper lock bonding part above the cover of latched position; The inclined plane butt of the upper surface of Zhao bottom sticking department and upper lock bonding part then; And be directed into the latched position identical with normal running, any of bottom sticking department and upper lock bonding part do not applied big load yet.
For the cover of closing in the horizontal direction with the mode that strides across the card accommodation section in the enable possition; Through making its slip; And move to latched position by the upper lock bonding part guiding that forms along the motion track of the bottom sticking department that moves in the horizontal direction, can be reliably the upper surface of bottom sticking department be directed to the position with the lower surface butt of upper lock bonding part.
In addition; The invention of scheme 2 is characterised in that; The side frame that is formed with the position of upper lock bonding part forms; To be to turn back and be downward U word shape in the top of the strip metal plate erect of long side direction with the horizontal direction; The front end face of downward U word shape is the lower surface of upper lock bonding part, and the lateral surface that turns back to U word shape is the upper surface of upper lock bonding part.

Below, use Fig. 1 to Figure 11 that the connector for memory card 1 of an embodiment of the invention is described.Explanation for the each several part of connector for memory card 1 in Fig. 1 (b), as above-below direction,, describes above-below direction with left as the place ahead right-hand as the rear.This connector for memory card 1 is made up of the housing body 3 shown in Fig. 4 (a), the cover 2 upper surface, shown in Fig. 5 (a) that is installed in a plurality of contacts 9 and covering shell main body 3 on the housing body 3.
In addition; Shown in Fig. 4 (a), the metal framework 32 that housing body 3 is formed by the box shape of the periphery that the metallic plate bending process become is surrounded the storage card of installing from the top 110 constitutes with the tabular insulating base 31 of rectangle fixing and that be installed in the inboard that is surrounded by metal framework 32.Therefore, be formed with the card accommodation section 10 that holds storage card 110 being erected at along between the side frame 32A of the both sides of the fore-and-aft direction of metal framework 32, on the bottom surface of card accommodation section 10, dispose insulating base 31.
On insulating base 31, utilize to embed be shaped and be fixed with eight contacts 9 integratedly, on the position of the contact site of each contact 9 and shank, be formed with window aperture and otch.Thus, the contact site of each contact 9 from window aperture towards the card accommodation section 10 in, and with conductive spacer (not shown) Elastic Contact that is contained in the storage card 110 in the card accommodation section 10.In addition, the shank soldering is connected on the printed circuit board (PCB) 15 on the corresponding signal bonding land figure, through forming window aperture and otch, can be from the top Visual Confirmation soldering connecting portion.
The housing sticking department 8 that forms at two places separately of side frame 32A is formed at: cover 2 from after the enable possition stated when sliding into latched position, along the top of the motion track of the cover sticking department 6 that moves along side frame 32A and be equipped with the position of lower surface 8a.Shown in Fig. 1 b, between the housing sticking department 8 at the place ahead that is formed at side frame 32A and rear, laterally, the overhanging integratedly upper end that is supported on the banded side plate of setting of banded control strip 12 of downward U word shape.
In addition, be formed with near the banded side plate of the front end at the side frame 32A of both sides respectively, erectting and cover 2 rotated and the dead eye 4 of free sliding ground support cover 2.The side frame 32A at position that is formed with dead eye 4 is shown in Fig. 4 (a), Fig. 4 (b), turns back to the inside and be downward U word shape in the top of banded side plate.Be downward U word shape through being turned back in top, the intensity of side frame 32A that is formed with the position of dead eye 4 increases, in addition, as after state, the pivot 5 of lateral surface cover for conducting 2 in dead eye 4 of U word shape becomes easy thereby cover 2 assemblings on housing body.
At the front end of the banded side plate that is formed with dead eye 4, also be connected with rectangular setting support chip 7 integratedly in its place ahead.As shown in Figure 9; For erectting support chip 7; After the pivot 5 that will cover 2 inserts in the dead eye 4; With respect to the banded side plate of erectting at fore-and-aft direction; Direction of insertion to pivot 5; I.e. bending vertically to the inside in this execution mode, and soldering is on the ground connection figure 16 of the printed circuit board (PCB) 15 that connector for memory card 1 is installed.
Shown in Fig. 5 (a); Cover 2 is that the cross section is that コ word shape forms with the bending of a conductive metal plate, by the cover main body 2a of the top that covers card accommodation section 10 with cover 2b from a pair of side of vertically along the both sides of the fore-and-aft direction of cover main body 2a setting up, slide and constitute along the outside of the side frame 32A of housing body 3.Side cover 2b is a little forwards outstanding from cover main body 2a, forms the circular pivot 5 shown in Fig. 5 (b) to the inside in its outstanding front portion.The external diameter of pivot 5 forms the length shorter slightly than the above-below direction width of dead eye 4 with the mode in the dead eye 4 that can be inserted into housing body 3 sides with a gap.Therefore; If allow pivot 5 pass dead eye 4, then pivot 5 freely slides at fore-and-aft direction between the latched position of the enable possition of the front end of dead eye 4 and rear end; Thereby no matter cover 2 in the optional position of enable possition and latched position, all can freely rotate around pivot 5.
Each side cover 2b is formed with the cover sticking department 6 that is equivalent to the bottom sticking department on position, two places.Cover sticking department 6 covers the コ word shape that 2b is punched to a type with the side, and will be the crank-like that the rectangular pieces of profile forms to the inside, forms to the top flange with the otch.Bending is the upper surface 6a of the front end face of crank-like for the cover sticking department that engages with the lower surface 8a of housing sticking department 8.Shown in Fig. 2 (b); When being closed in pivot 5 and being positioned at the cover 2 of enable possition of front end of dead eye 4; Cover sticking department 6 is respectively formed at the anterior position of housing sticking department 8, even and cover 2 and rotate in the enable possition, cover sticking department 6 is formed on also not the position with housing sticking department 8 butts.
In addition, the centre at the cover sticking department 6 at two places that are formed at each side cover 2b is formed with outstanding to the inside lug boss 13.Lug boss 13 is formed on: when cover 2 slides between enable possition and latched position with the state that covers and close card accommodation section 10, cross the position that the medial surface of 2b is covered in the side of the banded control strip 12 of side frame 32A side.
As shown in Figure 8, the pair of pivot 5 that the relative position that above-mentioned cover 2 will cover 2b from the side is outstanding is to the inside depressed and is assembled on the housing body 3 from the direction of the last direction dead eye 4 of the side frame 32A at the position that is formed with dead eye 4.Owing to turn back and be downward U word shape in the top that is formed with the banded side plate of dead eye 4, therefore, the lateral surface butt that pivot 5 is crooked with it, crooked to the inside through banded side plate, guiding pivot 5 and in its insertion dead eye 4.In addition, erect support chip 7 when this is assembled, the mode crooked to the inside with banded side plate is positioned on the elongated surfaces of banded side plate, after inserting pivot 5 in the dead eye 4, and bending vertically to the inside.
On the printed circuit board (PCB) 15 that is formed with the signal bonding land figure that is electrically connected storage card 110, cover 2 is installed to connector for memory card 1 on the housing body 3 is mounted to shank soldering with each contact 9 on the figure of signal bonding land.At this moment, printing is formed with ground connection figure 16 on the surface of the printed circuit board (PCB) 15 relative with the setting support chip of the base plate bending vertically of metal framework 32 7, the many places of base plate with erect support chip 7 solderings on ground connection figure 16.Thus, the cover 2 that the metal framework 32 around the encirclement card accommodation section 10, pivot 5 and cover sticking department 6 contact with metal framework 32 also is earthing potential, thereby is contained in the almost whole conductively-closed on every side of the memory feature 110 in the card accommodation section 10.In addition, be fixed on the surface of printed circuit board (PCB) 15 through erectting support chip 7, the strip metal plate that is formed with dead eye 4 is difficult to bending to the inside, receives unexpected external force even cover 2, and pivot 5 can not come off from dead eye 4 yet.
Below, to the explanation of the order of Fig. 3 storage card 110 is installed in the operation on the connector for memory card 1 of formation like this according to Fig. 1.Installing under the situation of storage card 110, at first, the pivot 5 of cover 2 is being moved to the front end of dead eye 4, opening the cover 2 that is in the enable possition with the mode shown in Fig. 1 (a), Fig. 1 (b), and storage card 110 is configured in the card accommodation section 10.Be contained in storage card 110 in the card accommodation section 10 around by metal framework 32 location, each conductive spacer that exposes in the bottom surface with contact towards the contact site that blocks the contact 9 in the accommodation section 10.
Can freely rotate around pivot 5 in the enable possition because cover 2, therefore, then, shown in Fig. 2 (a), Fig. 2 (b), cover 2 turned to the levels that cover main body 2a covers the surface of storage card 110.Be positioned at the pivot 5 of enable possition because be located in the enable possition of front end from its rear butt towards the spacer 11 of dead eye 4, therefore, even in the enable possition rotating mask 2, cover 2 and also do not rock at fore-and-aft direction.In addition; At cover 2 when being positioned at the enable possition, even because cover sticking department 6 is formed on the position that rotating mask 2 does not also disturb with housing sticking department 8, therefore; Turn to horizontal level even will cover 2, also be not positioned at the place ahead (with reference to Fig. 2 (b), Fig. 7) of housing sticking department 8 with housing sticking department 8 butts.
Under this state of closing cover 2; Pivot 5 can be crossed spacer 11 and in dead eye 4, rearward move; In addition; Because the tight rear at cover sticking department 6 is formed with housing sticking department 8; Therefore; If cover 2 is rearward flatly moved, the upper surface 6a that then respectively covers sticking department 6 is by in the lower surface 8a guiding of the housing sticking department 8 of square one-tenth thereafter, thereby can keep the posture of level rearward to slide.
When cover 2 is positioned at the enable possition; Be positioned at the place ahead of the banded control strip 12 in the overhanging outside that is supported on side frame 32A to the outstanding lug boss 13 of the medial surface of side cover 2b; If cover 2 is rearward slided with the posture of level, then lug boss 13 is crossed the lateral surface of banded control strip 12.Thus, to cover 2 from the enable possition during latched position is carried out slide, can access and the similar rhythm and pace of moving things of " click is rattled away " sense, the operator can understand the situation of conversion enable possition and latched position through slide cover 2.Especially in the application's invention; Because covering 2 can rotate in arbitrary position of enable possition and latched position; Therefore; Can open under cover 2 the state from the enable possition to latched position it is carried out slide (below; This operation is called maloperation); By carrying out slide with the posture of level to covering 2; The upper surface 6a that makes cover sticking department 6 along the lower surface 8a of housing sticking department 8 from the enable possition to latched position slide (below; This operation is called normal running); Make lug boss 13 produce the rhythm and pace of moving things of crossing banded control strip 12, can inform that the operator has carried out and the distinguishing normal running of maloperation.
Under normal operation, if make cover 2 rearward slide into the position of latched position that pivot 5 is in the rear end of dead eye 4, then the front end of spacer 11 from the place ahead butt, pivot 5 is positioned in the latched position of the rear end of dead eye 4.Therefore, cover 2 otherwise apply certain above external force that pivot 5 is crossed spacer 11, just can be positioned at the latched position shown in Fig. 3 (a), Fig. 3 (b).
In latched position; As shown in Figure 6, the upper surface 6a of cover sticking department 6 and the lower surface 8a butt of housing sticking department 8, thus restriction cover 2 is to the rotation of opening direction; Be contained in the upper surface quilt cover main body 2a extruding of the storage card 110 in the card accommodation section 10, thus contact 9 and conductive spacer Elastic Contact.
As stated; Even the connector for memory card of this execution mode 1 misoperation; Cover 2 is slided to latched position from the enable possition, as shown in figure 10, the opening that the cover 2 that arrives latched position because of misoperation does not engage for cover sticking department 6 and housing sticking department 8.In this misoperation; Because lug boss 13 does not produce the rhythm and pace of moving things of crossing banded control strip 12; Therefore; The operator who finds misoperation can make cover 2 forwards slide; Close cover 2 in latched position, thereby carry out normal running, but in this execution mode; Also can close the cover 2 that slides into latched position with misoperation by the strong hand, thereby make cover sticking department 6 engage with housing sticking department 8 and lock.
That is, if close the cover 2 that has carried out misoperation in latched position, as shown in figure 11, the crank-like of cover sticking department 6 dip down the inclined-plane with at the upper surface 8b butt that turns back to the outside curve of the housing sticking department 8 of downward U word shape.In addition; If to covering 2 active forces that apply closing direction; Then metal cover sticking department 6 is crooked on one side respectively with housing sticking department 8; On one side along the upper surface 8b of the inclination of housing sticking department 8 cover for conducting sticking department 6 downwards; If cross housing sticking department 8; The upper surface 6a that then covers sticking department 6 is relative with the lower surface 8a of housing sticking department 8, as shown in Figure 6, and engaging mutually.Thus, identical with normal running, in latched position, cover 2 is by housing body 3 lockings.
Under the situation that storage card 110 is extracted from connector for memory card 1, the active force of crossing spacer 11 with pivot 5 forwards carries out slide to the cover 2 of the latched position shown in Fig. 3 (a), Fig. 3 (b).The cover 2 that slides into the enable possition from latched position is also identical with rightabout; The upper surface 6a of cover sticking department 6 is directed to the lower surface 8a of the housing sticking department 8 that is formed on its rear; And the posture of maintenance level is slided; In addition; Betwixt, produce the rhythm and pace of moving things that lug boss 13 is crossed banded control strip 12.
Come off and can freely rotate from housing sticking department 8 because arrive the cover sticking department 6 of the cover 2 of enable possition, therefore, can shown in Fig. 1 (a) Fig. 1 (b), open, thereby extract storage card 110.
In the above-described embodiment, on the side frame 32A that constitutes by metal framework 32, formed dead eye 4 and housing sticking department 8, but side frame is not restricted to metallic, also can be by forming with insulating base 31 identical synthetic resin.
In addition, be that example is illustrated to cover that 2 side cover 2b slides along the outside of side frame 32A, but also can along inner slide.In this case, certain, housing sticking department 8 is formed on the inboard of side frame 32A, and cover sticking department 6 is formed on the outside of side cover 2b.
In addition, also can be as existing connector for memory card 100, before cover 2 moved to latched position, storage card all can temporarily remain on cover 2 sides.
In addition, the side frame 32A that is formed with the position of dead eye 4 turns back the top of banded side plate to the inside and is downward U word shape, but its direction is arbitrarily, also can turn back laterally to be downward U word shape.
The present invention is applicable to the connector for memory card that storage card is connected on the electronic equipments such as mobile phone.
