Again, in the left and right sides of above-mentioned mounting table portion 6b, up with the region of the support substrate 6 of drive plate 5 covering, form a pair plate spring sheet 8 cut obliquely from " コ " shape groove along fore-and-aft direction.A pair plate spring sheet 8 abuts with the bottom surface of drive plate 5, plays a part the means of energizing (energized mechanisms) as being energized in the direction in drive plate 5 location-plate portion 7 upward.
Drive plate 5 surrounds the rectangular-shaped small card location hole 5a of the appearance profile of nano-SIM card 40 by being formed, be formed as ring flat-plate shape, the lateral surface of ring flat-plate shape is led by the prerotation vane 6d inwards outstanding everywhere of the stator portion 6a from support substrate 6, to keep the state of flat-hand position, support substrate 6 moves up and down.The position of the formation small card location hole 5a of drive plate 5 is as shown in Fig. 8 (a), when the chuck 4 installing nano-SIM card 40 is received to the card coupling recess portion 21 of connector body 2, six electrode land 41a of the nano-SIM card 40 being positioned at small card location hole 5a are contacted with the movable contact 3a subtend of contact 3 corresponding respectively, determines its position.
Location-plate portion 7 is formed with synthetic resin, there is the rectangle frame portion 7c of the profile along support substrate 6, the projecting left and right lateral surface at rectangle frame portion 7c of fitting projection 7b, makes from the inner side of stator portion 6a described fitting projection 7b be fitted together to embedded hole 6c, is assembled on support substrate 6.Thus, side in being surrounded by support substrate 6 and rectangle frame portion 7c, forms the card mounting recess 9 that storage card 30,40 is supported in location.Above card mounting recess 9, flange 7d is connected with integral from 7c upper end, rectangle frame portion towards interior side, is formed the large-scale card location hole 7a of the appearance profile surrounding micro-SIM card 30 by the inner peripheral of flange 7d.About the position of large-scale card location hole 7a being formed in location-plate portion 7, as shown in Fig. 7 (a), when the chuck 4 installing micro-SIM card 30 is received to the card coupling recess portion 21 of connector body 2, six electrode land 31a of the micro-SIM card 30 being positioned at large-scale card location hole 7a are contacted with the movable contact 3a subtend of contact 3 corresponding respectively, determines its position.
Namely, the each interelectrode relative position of six electrode land 31a of the micro-SIM card 30 shown in six electrode lands 41a with Figure 10 (b) of the nano-SIM card 40 shown in Fig. 9 (b) is roughly the same, pair of electrodes bonding land 41a, 31a of being exposed to correspondence position flow through the same signal of telecommunication, play identical linkage function, therefore, determine the large-scale card location hole 7a of relative chuck 4 and the forming position of small card location hole 5a, make to be connected with the general contact 3 of connector body 2 side.But, although the quantity being exposed to the contact 3 in card coupling recess portion 21 increases, also can carry out the location of the storage card 30,40 of two kinds being arranged on card mounting recess 9, make to be connected with each self-corresponding contact 3.
Large-scale card location hole 7a becomes the opening of card mounting recess 9, is covered around it by flange 7d, and therefore, in card mounting recess 9, the drive plate 5 of energizing upward abuts with flange 7d, prevents from coming off.
The height in location-plate portion 7 is designed to following height: when being assembled on support substrate 6 in location-plate portion 7, and the height from the mounting table portion 6b of support substrate 6 to surface, location-plate portion 7 becomes the 0.76mm being equivalent to micro-SIM card 30 thickness.Thus, be supported in the surface of the micro-SIM card 30 on the mounting table portion 6b in card mounting recess 9 and the continuous with the same face of the plane as chuck 4 above, micro-SIM card 30 does not abut with the around openings of card coupling recess portion 21, chuck 4 can be inserted to card coupling recess portion 21.On the other hand, the thickness of nano-SIM card 40 is 0.67mm, roughly equal with the thickness of micro-SIM card 30, therefore, can be supported in card mounting recess 9, its surface can not be given prominence to above chuck 4, roughly become the same face.
At this, because the Thickness Ratio mini memory card 40 of large-scale storage card 30 is thick slightly, therefore, strictly speaking, the surface that positioning support is held in both cards of card mounting recess 9 does not become sustained height, but, if the Thickness Ratio of mini memory card 40 large-scale storage card 30 is thick, then by the Height Adjustment of drive plate 5 that is depressed because installing large-scale storage card 30 to the position higher than mounting table portion 6b, can the same face be set to.
The chuck 4 of above-mentioned formation is under the state of not installing storage card 30,40, and as shown in Figure 6, plate spring sheet 8 pushes drive plate 5 upward, and drive plate 5 abuts with the inner top surface of flange 7d, makes small card location hole 5a standby in the face of the inner side of large-scale card location hole 7a.When nano-SIM card 40 is connected occasion to the connector body 2 of electronic equipment side, by nano-SIM card 40 as shown in Figure 8, to make surface sides to the posture of top, be configured on the mounting table portion 6b in the small card location hole 5a of the drive plate 5 be pushed upward.Thus, nano-SIM card 40 orthogonal two directions of small card location hole 5a are all around located, and surface is exposed to the roughly the same face above with chuck 4, is supported in card mounting recess 9.
Then, the reverse up and down of the chuck 4 of nano-SIM card 40 is installed if make, card coupling recess portion 21 to connector body 2 is inserted, until its front end abuts with barrier 24d, be accommodated in card coupling recess portion 21, then each electrode land 41a of nano-SIM card 40 and the movable contact 31a Elastic Contact of the contact 3 at the subtend position in card coupling recess portion 21, nano-SIM card 40 is electrically connected with electronic equipment side.
Again, when nano-SIM card 40 occasion of fech connection, if extract chuck 4 out from card coupling recess portion 21, depress presses the drive plate 5 of the chuck 4 of lower reverse, then nano-SIM card 40 is given prominence to from small card location hole 5a, can easily take out from card mounting recess 9.
When micro-SIM card 30 is connected occasion to connector body 2, by micro-SIM card 30 as shown in Figure 7, to make surface sides to the posture of top, be configured on the drive plate 5 in the large-scale card location hole 7a in location-plate portion 7, the elasticity of resistance plate spring sheet 8, down push drive plate 5, receive to card mounting recess 9.Thus, micro-SIM card 30 orthogonal two directions of large-scale card location hole 7a are all around located, and with the state that surface is outstanding slightly above chuck 4, are supported in card mounting recess 9.
Then, the reverse up and down of the chuck 4 of micro-SIM card 30 is installed if make, be inserted in the card coupling recess portion 21 of connector body 2, then because card coupling recess portion 21 is formed as the size loosening chimeric chuck 4, therefore, the surface of micro-SIM card 30 back to chuck 4 above the same face, if in the position that the front end of chuck 4 abuts with barrier 24d, be accommodated in card coupling recess portion 21, then each electrode land 31a of micro-SIM card 30 and the movable contact 31a Elastic Contact of the contact faced by subtend 3, be electrically connected with electronic equipment.
Again, when micro-SIM card 30 occasion of fech connection, make to reverse up and down if extract chuck 4 out from card coupling recess portion 21, then because up being pushed by drive plate 5, micro-SIM card 30 is outstanding above chuck 4, can easily take out from card mounting recess 9.
In above-mentioned example, storage card 30,40 in the large-scale card location hole 7a formed with the opening closed by inner peripheral or small card location hole 5a locator card mounting recess 9, but, if in two directions orthogonal with the plane of chuck 4 up and down, each storage card 30,40 is positioned, then not necessarily must position with the inner peripheral of closing any opening, also can drive plate 20 be such as shown in figure 11, ring-type local detachment, the partly open of inner peripheral.Further, also can form a part for the profile of large-scale card location hole 7a or small card location hole 5a at the inner peripheral of the flange 7d or drive plate 5 that are divided into multiple parts, storage card 30,40 is positioned.
Again, in above-mentioned first example, the electrode land 31,41 of storage card 30,40 is exposed to opening (the large-scale card location hole) 7a of the card mounting recess 9 of the top side of chuck 4, but, also connecting hole can be set in the inner bottom surface side of card mounting recess, make it be exposed in connecting hole.Below, with reference to Figure 12 to Figure 14, the connector for memory card 10 that the present invention second example wearing connecting hole at card mounting recess relates to is described.Compared with the connector for memory card 1 that this connector for memory card 10 and the first example relate to, the structure difference of connecting hole 13 is only worn at the card mounting recess 12 of chuck 11, therefore, be marked with same-sign for structure that is identical with the first example or that play same purpose, it illustrates omission.Again, in this connector for memory card 10, do not make the reverse up and down of chuck 11, the card coupling recess portion 21 to connector body 2 is received, and therefore, makes the above-below direction of chuck 11 consistent with the above-below direction of connector body 2, illustrates that it is formed.
As shown in Figure 12 (a), (b), the support substrate 14 formed with by sheet metal with location-plate portion 7 within it square become card mounting recess 12, at the inner bottom surface of card mounting recess 12, form connecting hole 13, this connecting hole 13 is along fore-and-aft direction, for all otch of the central authorities forming mounting table portion 6b, banded opening.The region that six electrode lands 41 that the profile of the left and right sides of connecting hole 13 surrounds nano-SIM card 40 expose, but less than the profile of nano-SIM card 40, therefore, in the below of the small card location hole 5a of drive plate 5, connecting hole 13 is inside it.
When connection nano-SIM card 40 occasion, as shown in figure 13, to make the posture of back side surface to top of nano-SIM card 40, be configured on support substrate 14 by the small card location hole 5a of the drive plate 5 be pushed upward.Thus, nano-SIM card 40 orthogonal two directions of small card location hole 5a are all around located, and as shown in figure 14, each electrode land 41 being exposed to face side, to be exposed to the state in connecting hole 13, is supported in card mounting recess 12.
Then, the chuck 11 being installed with nano-SIM card 40 if make inserts with the card coupling recess portion 21 of identical posture to connector body 2, until its front end abuts with barrier 24d, be accommodated in card coupling recess portion 21, then the movable contact 31a of contact 3 is by each electrode land 41a Elastic Contact of connecting hole 13 with nano-SIM card 40, and nano-SIM card 40 is electrically connected with electronic equipment side.
When connection micro-SIM card 30 occasion, by micro-SIM card 30 to make back side surface to the posture of top, be configured on drive plate 5 by large-scale card location hole 7a, the elasticity of resistance plate spring sheet 8, down pushes drive plate 5, receives to card mounting recess 12.Thus, micro-SIM card 30 orthogonal two directions of large-scale card location hole 7a are all around located, and be exposed to the state of connecting hole 13, be supported in card mounting recess 12 at each electrode land 31 being exposed to face side.
Then, the chuck 11 being installed with micro-SIM card 30 if make inserts with the card coupling recess portion 21 of identical posture to connector body 2, until its front end abuts with barrier 24d, be accommodated in card coupling recess portion 21, then because card coupling recess portion 21 is formed as the size loosening chimeric chuck 11, therefore, the back side of micro-SIM card 30 abuts with the inner top surface of card coupling recess portion 21, the movable contact 31a of the contact 3 given prominence to from the inner bottom surface of card coupling recess portion 21 is by each electrode land 31a Elastic Contact of connecting hole 13 with micro-SIM card 30, micro-SIM card 30 is electrically connected with electronic equipment side.
According to the connector for memory card 10 that this second example relates to, when being installed with storage card 30, when the chuck 11 of 40 inserts to the front of the card coupling recess portion 21 of connector body 2, from the movable contact 31a of the contact 3 that the inner bottom surface of card coupling recess portion 21 is given prominence to, do not cross from storage card 30, the support substrate 14 that the surface of 40 is given prominence to downward, but be exposed to the storage card 30 of the banded connecting hole 13 between support substrate 14, the surface sliding of 40, with electrode land 31, 41 Elastic Contact, therefore, do not worry abutting with support substrate 14 and contact 3 occurs and be out of shape.
Again, the left and right sides of support substrate 14 below location-plate portion 7 be made up of conductive metal plate only forms band shape, therefore, when shaping location-plate portion 7, also integrally formed by inlaying shaping.
Further, the both sides being arranged on the electrode land 31,41 of the storage card 30,40 of chuck 4 are surrounded by support substrate 14, therefore, charged thing or electric conductor that outside can not occur contact accidentally, can prevent electrostatic breakdown or short circuit.
In above-mentioned each example, be described by micro-SIM card and the nano-SIM card example as large-scale storage card 30 and mini memory card 40 respectively, but also can be other storage card that profile varies in size, again, storage card profile is not limited to rectangle, even the storage card of various contour shape also can be suitable for the present invention.
Below, the present invention's utilizability is industrially described:
