By the convex surface contact site 3a of the 3b of foot of cantilever support and its free end side, grant prestressing force in the mode that tilts from stiff end downwards, hold under the state outstanding in the recess 7 at convex surface contact site 3a downward card below the first contact accommodation hole 2c, the spacer 3c of front end is connected to the first contact accommodation hole 2c from the top periphery is positioned.Side is the inclined plane that tilts rearward and downwards below the place ahead of convex surface contact site 3a, and when the SIM card 50 contact convex surface contact site 3a that rearward insert, the then 3b of foot deflection is kept out of the way in the first contact accommodation hole 2c up.Shown in Figure 10 (a), six electrodes 51 of SIM card 50, exposing with the rectangular dispersion of triplex row two row by the place ahead above it, the downward card in position that exposes of each electrode 51 of the SIM card 50 that the convex surface contact site 3a correspondence of each L word contact 3 is held to grow crosswise holds in the recess 7 outstanding.
The card of going up that is formed between the top and insulation board 2 of crown cap 5 holds recess 6 owing to hold the Micro SD card 60 that inserts along its length direction from the place ahead, so with width with highly respectively than the long a little profile of growing crosswise of w2, t2 opening forwards, the depth from opening to inboard the inside be the length of lacking than the length l 2 of the length direction of Micro SD card 60.Shown in Figure 10 (b), eight electrodes 61 of Micro SD card 60 are owing to the front below it is exposed on linearity ground on one side, so insert along its length, and be contained in eight elongated, belt-shaped contacts 4 that each electrode 61 of blocking the Micro SD card 60 that holds recess 6 is connected respectively with lengthwise and be installed in insulation board 2.
Eight elongated, belt-shaped contacts 4 respectively as shown in Figure 3, integral body forms thin broadband shape, the leaf spring contact site 4a of rearward front end and inclination support upward and the 4b of foot that the place ahead is connected and rearward draw on U word shape ground with leaf spring contact site 4a, same with L word contact 3, for the vertically die-cut conductivity metal sheet that is made of phosphor bronze forms.Eight elongated, belt-shaped contacts 4 insert with L word contact 3 and are formed on the insulation board 2 and are insulated plate 2 cantilever support, the leading edge cantilever support 4b of foot by the second top contact accommodation hole 2d that is formed on the insulation board 2 that is surrounded by upper frame 2a with the rectangular profile of growing crosswise, the leaf spring contact site 4a that is connected with its front rearward and is upward tilted, it is upwards blocked hold recess 6 interior giving prominence to.Upwards card holds recess 6 interior each outstanding leaf spring contact site 4a and eight electrode 61 Elastic Contact that linearity ground, one side exposes below Micro SD card 60, and this Micro SD card 60 inserts to go up to block along its length direction and holds recess 6.
Switch contact 10 is to be used to detect Micro SD card 60 insert and go up a pair of plate spring sheet that card holds recess 6, and its free end holds in the recess 6 with movable mode cantilever support in insulation board 2 at last card.
On the connector for memory card 1 that constitutes like this, as shown in Figure 1, when card holds recess 7 under SIM card 50 is inserted along its Width from the place ahead, then down card holds interval between the horizontal wide and internal face of opening of recess 7 only the length l 1 than the length direction of SIM card 50 is long a little, therefore, SIM card 50 fore-and-aft direction that blocks the card insertion direction that holds recess 7 under the edge is directed inserting.Thereby, the SIM card of inserting at fore-and-aft direction 50 with held four leaf spring oblique plate 5c, 5d of the inner bottom surface (below the metal-back 5) of recess 7 by cantilever support at card down any one all with very little angle of intersection, therefore, the front end of SIM card 50 enters from the cardinal extremity of each leaf spring oblique plate 5c, 5d, leaf spring oblique plate 5c, 5d being blocked the direction of the inner bottom surface that holds recess 7 downwards depresses, simultaneously, be inserted into and the position of blocking the inboard the inside butt that holds recess 7 down.During it inserts, SIM card 50 is connected to from following card to be held on the inclined plane of each convex surface contact site 3a of the side-prominent six roots of sensation L word contact 3 of the inner top surface of recess 7, each convex surface contact site 3a is when keeping out of the way to the first contact accommodation hole 2c, the 3b of foot deflection upward, each electrode 51 of Elastic Contact SIM card 50 correspondences.
At this moment, held in the recess 7 SIM card 50 application of force upward at card down in four leaf spring oblique plate 5c, 5d of inner bottom surface by cantilever support, SIM card 50 is held at following card and can be received in the recess 7 with rocking, and, since with each electrode 51 to each convex surface contact site 3a side application of force, so both with the regulation contact pressure be electrically connected more effectively.
In addition, follow the insertion of above-mentioned SIM card 50, on connector for memory card 1, block to hold and insert Micro SD card 60 in the recess 6 again along its length direction from the place ahead, then Micro SD card 60 is connected to each the leaf spring contact site 4a that holds eight elongated, belt-shaped contacts 4 that rearward tilt upward in the recess 6 at last card, in the time of the below deflection of each leaf spring contact site 4a in the second contact accommodation hole 2d, each electrode 61 Elastic Contact corresponding with Micro SD card 60.Thus, the SIM card 50 and the MicroSD card 60 that insert from same direction are divided into two-layer holding up and down, are electrically connected with electrode 51, the 61 pairing contacts 3,4 of each card 50,60.
On the other hand, last card hold recess 6 and down card hold recess 7 owing to, hold recess 7 so Micro SD card 60 that sometimes will be more small-sized misplugs into the following card that holds SIM card 50 at any one front opening all of insulation crust 2,5.Micro SD card 60 is shown in Figure 10 (b), owing to be formed with the recessed section portion 62 that uses fingerhold at its contour shape and rear end, card holds recess 7 under its length direction insertion of front end edge that is formed with recessed section portion 62 so can hold, but with respect to blocking the card insertion direction that holds recess 7 down is fore-and-aft direction, as Fig. 5, shown in Figure 7, when oblique insertion, then the front end of Micro SD card 60 is connected to one group of leaf spring oblique plate 5c with respect to direction of insertion with the angle near the right angle, the side of any one of 5d (being 5c in Fig. 5) is blocked under can not inserting under identical posture and is held in the recess 7.Thereby the oblique posture of Micro SD card 60 maintenances is contained in down card to be held in the recess 7, can not take out.In addition, operator owing to can not block downwards holds recess 7 and inserts, thereby recognizes and misplug into Micro SD card 60, inserts the correct card of going up and holds recess 6 and can change.
In addition, the card insertion direction (fore-and-aft direction) that holds recess 7 along following card misplug into Micro SD card 60, since with four leaf spring oblique plate 5c, 5d all with very little angular cross, therefore, the front end of Micro SD card 60 enters from the cardinal extremity of each leaf spring oblique plate 5c, 5d, will by leaf spring oblique plate 5c, the 5d of cantilever support downwards the card direction of holding the inner bottom surface (crown cap 5 following) of recess 7 depress, simultaneously, its front end is inserted into and the position of blocking the inboard the inside butt that holds recess 7 down to the rear along card insertion direction.Even the front end of Micro SD card 60 is inserted into and the position of blocking the inboard the inside butt that holds recess 7 down, there are the relation of l2 〉=w1 in the length l 2 of the length direction of Micro SD card 60 and the horizontal wide w1 of SIM card 50, as shown in Figure 8, to hold the opening of recess 7 outstanding and keep from compare the short following card of depth from opening to inboard the inside with the horizontal wide w1 of SIM card 50 for the front end of Micro SD card 60, can with misplug into Micro SD card 60 hold recess 7 from card down and pull out simply.
In the above-described embodiment, because the mode channeling conduct that Micro SD card 60 inserts according to its shape along its length with the operator, so when card holds recess 7 under mispluging, usually the depth direction that also following naturally card holds recess 7 inserts as length direction, must be that its front end exposes from blocking the opening that holds recess 7 down, become then and can take out.And, in the present embodiment, by four leaf spring oblique plate 5c, 5d are set, thereby forbid inserting Micro SD card 60 with the posture that tilts with respect to depth direction, therefore, make Micro SD card block the depth direction that holds recess 7 below 60 and insert, can hold recess 7 taking-ups from blocking down effectively as length direction.
Hold the mechanism of the depth direction of recess as forbidding with respect to following card, replace above-mentioned four leaf spring oblique plate 5c, 5d and also can use other structure with oblique posture insertion Micro SD card 60.Fig. 9 is that expression has the transverse sectional view of connector for memory card 30 of second embodiment of the invention of forbidding inserting with oblique posture other structures of Micro SD card 60.
This connector for memory card 30 holds on the inboard the inside 31a of recess 31, to be concaved with a plurality of grooves 32 of vertical direction arbitrarily at interval at the following card that holds SIM card 50 along growing crosswise.As shown in the figure, with respect to card insertion direction (fore-and-aft direction) downwards card hold recess 31 with the posture that tilts misplug into Micro SD card 60, after the front end corner part that tilts arrives inboard the inside 31a, then cooperate with the groove 32 of any one, and the front end in its bight blocks the sidewall 31b butt that holds recess 31 down with formation, therefore, part at MicroSD card 60 is given prominence under the state that keeps from blocking the opening that holds recess 31 down, can not insert.Thus, the operator realize misplug into, pinching from the outstanding part of opening, can be simply Micro SD card 60 be held recess 31 from card down and pull out.
Be arranged with this groove 32 and forbid the structure that Micro SD card 60 inserts with the posture that tilts, the mechanism that forbids that also can be adopted with leaf spring oblique plate 5c, the 5d of above-mentioned first execution mode also uses, by also using both, can more effectively Micro SD card 60 be inserted along blocking the card insertion direction that hold recess 7,31 down.
In the above-described embodiment, form above the insulation shell hold Micro SD card 60 on card hold recess 6, below form the following card hold SIM card 50 and hold recess 7, but so long as both at the equidirectional opening of insulation shell, then its configuration also can be opposite.
In addition, because four leaf spring oblique plate 5c, 5d cut from crown cap 5 and form, so even can become and plug the durability good quality production that storage card also is difficult to fatigue repeatedly, but not necessarily must form from crown cap.
