Description
Technical field
The present invention relates to the storage card being contained in accommodation section to be connected to the connector for memory card on electronic equipment, in more detail, relate in housing body and rotate between the cover being freely supported in housing body, storage card is positioned to the connector for memory card in card accommodation section.
Background technology
Now, there is as everyone knows following connector for memory card: after opening and rotating freely cover and storage card is contained in the card accommodation section of housing body with respect to housing body, close cover in the mode that covers the upper surface that is contained in the storage card in card accommodation section, and the rotation of lower restriction cover in off position.For the storage card being contained in card accommodation section, be electrically connected with the conductive spacer of storage card bottom surface towards the contact of card accommodation section from housing body, and be positioned between blocked cover and housing body with this state, therefore, during being electrically connected, not existing and make because of carelessness storage card vibration or deviate from from card accommodation section.
In the connector for memory card of this structure, in order to insert storage card, making the cover that the mode of the upper surface that covers storage card closes is to rotate enable possition freely to slide 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 to (patent documentation 1: TOHKEMY 2008-287919 communique).
Figure 12 to Figure 14 represents 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, by erectting side frame 101 is set along dual-side, thereby be formed with betwixt the card accommodation section 103a that multiple contacts 102 are faced; This knuckle guard 106 is outstanding is provided with the pivot 105 being inserted in the dead eye 104 that the front (right-hand in Figure 14) of side frame 101 wears, and can rotate around pivot 105.
The front of dead eye 104 is formed as the elongated slot 104b take fore-and-aft direction as long side direction, its rear side is formed as 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 dead eye 104 is the oblong shape embedding with a gap in elongated slot 104b, and the width of its long side direction is the length slightly shorter than the diameter of circular 104a.Therefore, knuckle guard 106 is in the time that pivot 105 is positioned at the enable possition (Figure 13) of the rear position of dead eye 104, can freely rotate with respect to housing body 103, pivot 105 can move with the posture of knuckle guard 106 of the upper surface of closing covering shell main body 103 in elongated slot 104a, 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 being shaped integratedly with the housing body 103 from the side lateral surface of frame 101 is outstanding.The two sides of knuckle guard 106 are the faces that slide along the lateral surface of this side frame 101, and are formed with the bottom locking plate 108 that is forwards formed as L word shape.As shown in figure 13, bottom locking plate 108 is formed on: in the time rotating enable possition freely, be positioned at the rear of top locking accessory 107 at knuckle guard 106, and in the time of the latched position in sliding into front, the position engaging with the below of top locking accessory 107.
In the situation that storage card 110 being arranged on this connector for memory card 100, as shown in figure 12, storage card 110 is inserted in the rear square frame 106a of portion of the knuckle guard 106 of opening enable possition and temporary transient maintenance, as shown in figure 13, knuckle guard 106 is turned to level, and close in 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 pivot 105 is moved to as the latched position shown in Figure 14 of the front position of dead eye 104.If knuckle guard 106 is forwards slided, 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, the contact 102 corresponding with each conductive spacer of being clamped, locate and be supported on the storage card 110 in the 103a of card accommodation section by knuckle guard 106 with housing body 103 is electrically connected with conductive spacer Elastic Contact.
In the situation that extracting storage card 110, contrary with said sequence, make knuckle guard 106 rearward slide into enable possition, thus hinge-opening cover 106 take out card storage card 110.
Use in connector 100 in said memory card, 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, front 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 if knuckle guard 106 is the postures that tilt a little from horizontal direction, also can slide into latched position from enable possition.
The in the situation that of movement to latched position with this faulty operation at knuckle guard 106, because bottom locking plate 108 is above top locking accessory 107, both do not engage, therefore, if want upward hinge-opening cover 106 forcibly, pivot 105 or elongated slot 104b are likely damaged.In addition, close and locking hinge cover 106 forcibly if want, bottom locking plate 108 is from top and top locking accessory 107 butts, and bottom locking plate 108 or top lock any one all likely breakage of accessory 107.
Therefore, different from the plastic housing body 103 of insulating properties, top is locked to accessory 107 and process to be difficult to damaged metallic plate, but because top locking accessory 107 protrudes from the side of side frame 101, therefore, finger of operator etc. may be touched and become injured reason.
In addition, pivot 105 is in order to obtain the intensity of regulation, and the length that need to make the short side direction of longitudinal section is certain above length, is oblong shape owing to making the profile in cross section, and therefore, the length of long side direction also needs to lengthen according to the length of short side direction.Its result, the internal diameter of the circular 104a of dead eye 104 has expanded 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

Embodiment
Use Fig. 1 to Figure 11 that the connector for memory card 1 of an embodiment of the invention is described below.For the explanation of the each several part of connector for memory card 1, in Fig. 1 (b), using above-below direction as above-below direction, using right-hand as front, left is described as 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 arranged on multiple contacts 9 in housing body 3 and covering shell main body 3.
In addition, as shown in Fig. 4 (a), the metal framework 32 that housing body 3 forms by metallic plate bending process is become to surround the peripheral rectangle frame shape of the storage card 110 of installing from top forms with fixing and be arranged on the tabular insulating base 31 of the rectangle of the inner side being 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 embedding be shaped and be fixed with integratedly eight contacts 9, on the contact site of each contact 9 and the position of shank, be formed with window aperture and otch.Thus, the contact site of each contact 9 from window aperture towards card accommodation section 10 in, and with conductive spacer (not shown) Elastic Contact that is contained in the storage card 110 in card accommodation section 10.In addition, shank soldering is connected on signal bonding land figure corresponding on printed circuit board (PCB) 15, by forming window aperture and otch, and can be from top Visual Confirmation soldering connecting portion.
The housing sticking department 8 that two places form separately at side frame 32A is formed at: at cover 2 while sliding into latched position from enable possition described later, along the top of the motion track of the cover sticking department 6 moving along side frame 32A and be equipped with the position of lower surface 8a.As shown in Figure 1 b, be formed between the front of side frame 32A and the housing sticking department 8 at rear, laterally, banded control strip 12 upper end of the overhanging banded side plate that is supported on setting integratedly of downward U-shaped.
In addition, on the banded side plate of erectting, be formed with the dead eye 4 that makes to cover 2 rotations and free sliding ground support cover 2 near the front end at the side frame 32A of both sides respectively.Being formed with the side frame 32A at position of dead eye 4 as shown in Fig. 4 (a), Fig. 4 (b), turns back to the inside as downward U-shaped in the top of banded side plate.By being turned back in top into downward U-shaped, be formed with the strength increase of the side frame 32A at the position of dead eye 4, in addition, as described later, the lateral surface of U-shaped is to the pivot 5 of the interior cover for conducting 2 of dead eye 4, thus the assembling of cover 2 in housing body becomes easy.
Being formed with the front end of banded side plate of dead eye 4, be also connected with integratedly rectangular setting support chip 7 in its front.As shown in Figure 9, for erectting support chip 7, after in the pivot 5 of cover 2 is inserted to dead eye 4, with respect to the banded side plate of erectting at fore-and-aft direction, to the direction of insertion of pivot 5, i.e. vertically bending to the inside in the present embodiment, and soldering is on the ground connection figure 16 of printed circuit board (PCB) 15 that connector for memory card 1 is installed.
As shown in Fig. 5 (a), cover 2 is that cross section is that コ word shape forms by the bending of a conductive metal plate, covers 2b and forms by covering a pair of side of vertically setting up, sliding along the outside of the side frame 32A of housing body 3 in the cover main body 2a of top of card accommodation section 10 and the both sides of the fore-and-aft direction from along cover main body 2a.Side cover 2b is a little forwards outstanding from cover main body 2a, forms to the inside the circular pivot 5 shown in Fig. 5 (b) in its outstanding front portion.The external diameter of pivot 5 is formed as the length slightly shorter than the above-below direction width of dead eye 4 in the mode that can be inserted into a gap in the dead eye 4 of housing body 3 sides.Therefore, if allow pivot 5 through dead eye 4, pivot 5, between the enable possition of the front end of dead eye 4 and the latched position of rear end, freely slides at fore-and-aft direction, thereby cover 2, no matter 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 bottom sticking department on two positions, place.Cover sticking department 6 covers side 2b and is punched to the コ word shape of a type, and by the crank-like that the rectangular pieces take otch as profile forms to the inside, flange forms upward.Bending is that the front end face of crank-like is the upper surface 6a of the cover sticking department that engages with the lower surface 8a of housing sticking department 8.As shown in Fig. 2 (b), in the time being closed in pivot 5 and being positioned at the cover 2 of enable possition of the 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 rotates in enable possition, cover sticking department 6 is formed on also not the position with housing sticking department 8 butts.
In addition, in the centre of cover sticking department 6 at two places that is formed at each side cover 2b, be formed with outstanding to the inside lug boss 13.Lug boss 13 is formed on: in the time that cover 2 slides between enable possition and latched position to cover and to close the state of card accommodation section 10, cross the position of the medial surface of the side cover 2b of the banded control strip 12 of side frame 32A side.
As shown in Figure 8, the pair of pivot 5 that above-mentioned cover 2 is given prominence to the relative position that covers from the side 2b to the inside, from be formed with dead eye 4 position side frame 32A the direction of direction dead eye 4 depress and be assembled in housing body 3.Owing to turning back as downward U-shaped in the top of the banded side plate that is formed with dead eye 4, therefore, the lateral surface butt that pivot 5 is bending with it, bending to the inside by banded side plate, guiding pivot 5 and it inserts in dead eye 4.In addition, erect support chip 7 in the time of this assembling, with banded side plate to the inside bending mode be positioned in the elongated surfaces of banded side plate, in pivot 5 is inserted to dead eye 4 after, vertically bending to the inside.
On the printed circuit board (PCB) 15 of signal bonding land figure that is formed with electrical connection storage card 110, cover 2 connector for memory card 1 that are installed in housing body 3 are mounted to the shank soldering of each contact 9 on the figure of signal bonding land.Now, on the surface of the printed circuit board (PCB) 15 with relative with the setting support chip 7 of the vertically bending of base plate of metal framework 32, printing is formed with ground connection figure 16, the many places of base plate with erect support chip 7 solderings on ground connection figure 16.Thus, the cover 2 that encirclement card accommodation section 10 metal framework 32, pivot 5 and cover sticking department 6 around contacts with metal framework 32 is also earthing potential, thereby is contained in the almost overall conductively-closed of surrounding of the memory feature 110 in card accommodation section 10.In addition, by being fixed on the surface of printed circuit board (PCB) 15 erectting support chip 7, the strip metal plate that is formed with dead eye 4 is difficult to bending to the inside, even if cover 2 is subject to unexpected external force, pivot 5 also can not come off from dead eye 4.
To the order explanation of Fig. 3, storage card 110 is arranged on to the operation on the connector for memory card 1 of formation like this according to Fig. 1 below.In the situation that storage card 110 is installed, first, the pivot 5 of cover 2 is moved to the front end of dead eye 4, open in the mode shown in Fig. 1 (a), Fig. 1 (b) cover 2 that is in enable possition, and storage card 110 is configured in card accommodation section 10.The surrounding that is contained in the storage card 110 in card accommodation section 10 is located by metal framework 32, and the each conductive spacer exposing in bottom surface contacts with the contact site of the contact 9 in card accommodation section 10.
Because cover 2 can freely rotate around pivot 5 in enable possition, therefore, then, as shown in Fig. 2 (a), Fig. 2 (b), cover 2 is turned to the surperficial level of cover main body 2a covering 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 at enable possition rotating mask 2, cover 2 does not also rock at fore-and-aft direction.In addition, in the time that cover 2 is positioned at 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, even cover 2 is turned to horizontal level, be not also positioned at the front (with reference to Fig. 2 (b), Fig. 7) of housing sticking department 8 with housing sticking department 8 butts.
Closing under this state of cover 2, pivot 5 can be crossed spacer 11 and rearward move in dead eye 4, in addition, because at the housing sticking department 8 that is formed with immediately rear of cover sticking department 6, therefore, cover 2 if make and rearward flatly move, the upper surface 6a that respectively covers sticking department 6 is by guiding at the lower surface 8a of the housing sticking department 8 of square one-tenth thereafter, thereby can keep the posture of level rearward to slide.
In the time that cover 2 is positioned at enable possition, be positioned at the front of the banded control strip 12 in the overhanging outside that is supported on side frame 32A to the outstanding lug boss 13 of medial surface of side cover 2b, cover 2 if make and rearward slide with the posture of level, lug boss 13 is crossed the lateral surface of banded control strip 12.Thus, to cover 2 carry out slide from enable possition to latched position during, can obtain feeling the similar rhythm and pace of moving things to " click is rattled away ", operator, by slide cover 2, can understand the situation of conversion enable possition and latched position.Especially in the present application, because cover 2 can rotate in arbitrary position of enable possition and latched position, therefore, can under the state of opening cover 2, carry out slide (below from enable possition to latched position to it, this operation is called to misoperation), by carrying out slide to covering 2 postures with level, make the upper surface 6a that covers sticking department 6 slide (following to latched position from enable possition along the lower surface 8a of housing sticking department 8, this operation is called to normal running), make lug boss 13 produce the rhythm and pace of moving things of crossing banded control strip 12, can inform that operator has carried out and the distinguishing normal running of misoperation.
Under normal operation, cover 2 positions that rearward slide into the latched position of the rear end of pivot 5 in dead eye 4 if make, the front end of spacer 11 is from front butt, and pivot 5 is positioned in the latched position of the rear end of dead eye 4.Therefore, cover 2 otherwise the certain above external force that applies pivot 5 and cross spacer 11 just can be positioned at the latched position shown in Fig. 3 (a), Fig. 3 (b).
