FIG. 9A is an explanatory view showing a state in which the memory card 10 and the connector 50 for the memory card 10 according to the first embodiment are coupled together, and FIG. 9B is a sectional view taken along line BB in FIG.
As shown in FIG. 8, the connector 50 has a plurality of connection terminals 54 that are elastically contactable (contactable) with each contact piece 22 of the memory card 10 so as to face the insertion slot 52 into which the memory card 10 is inserted. They are arranged in a direction orthogonal to the insertion direction.
As shown in FIG. 8, the connection terminal 54 includes ten connection terminals 54 </ b> A corresponding to the contact pieces 1 to 10 and four connection terminals 54 </ b> B corresponding to the contact pieces 11 to 14. .
The ten connection terminals 54A are arranged side by side in a direction orthogonal to the insertion direction.
The connection terminal 54B corresponding to the contact piece 11 is disposed between the two connection terminals 54A corresponding to the contact pieces 3 and 4.
The connection terminal 54B corresponding to the contact piece 12 is disposed between the two connection terminals 54A corresponding to the contact pieces 4 and 5.
The connection terminal 54B corresponding to the contact piece 13 is disposed between the two connection terminals 54A corresponding to the contact pieces 6 and 7.
The connection terminal 54B corresponding to the contact piece 14 is disposed between the two connection terminals 54A corresponding to the contact pieces 7 and 8.
The length of the connection terminal 54B along the insertion direction is formed with a dimension larger than the length of the connection terminal 54A along the insertion direction, and the tip at which the connection terminal 54B contacts the contact pieces 11 to 14 is: The connection terminal 54 </ b> B is configured to be located closer to the base portion 2002 of the contact piece region 20 than the tip that contacts the contact pieces 1 to 10.
In other words, the location of the connector 50 corresponding to at least one piece region 20 of the 20 piece regions between the adjacent partition walls 1410 is spaced 3 in the direction orthogonal to the insertion direction. Two connection terminals 54A, 54B and 54A are provided.
Two connection terminals 54A, 54A on both sides of the three connection terminals 54A, 54B, 54A are shorter in the insertion direction than one connection terminal 54B between the two connection terminals 54A, 54A. Is formed.
As shown in FIG. 9, by attaching the memory card 10 of the first embodiment to the connector 50, the eight contact pieces 3, 4, 7, 8, 11 to 14 and the eight connection terminals 54A and 54B are used. Bit parallel data signals SIDO0 to SIDO7 can be input and output.

According to the first embodiment, since four pieces of contact pieces 11 to 14 are provided in addition to the ten pieces of contact pieces 1 to 10 that have been conventionally provided, The four contact pieces 3, the contact piece 4, the contact piece 5, the contact piece 7, and the newly added four contact pieces 11 to 14, which are four contact pieces in total, It is possible to input / output 8-bit parallel data signals SIDO0 to SIDO7 through a total of eight pieces. In other words, by using the first contact piece 24 and the second contact piece 26, the bit width of the input / output data signal can be expanded. This is advantageous in increasing the bit width of the data signal and increasing the data transfer rate.
For example, the data transfer rate can be doubled as compared with a conventional memory card B that inputs and outputs data signals in a 4-bit parallel format.
Further, since there is no need to set the transfer clock to a high frequency, it is not necessary to change the transmission path of the memory card, and the cost of the memory card 10 can be avoided.
Further, as shown in FIG. 6, a gap S2 having a width larger than the gap S1 between the wide portions 2404 of the first contact piece 24 is provided between the width details 2402 of the two adjacent first contact pieces 24. Since the second contact piece 26 is formed in the gap S2 between the width details 2402 of the two adjacent first contact pieces 24 formed from the base portion 2002 to the intermediate portion 2006 of the contact piece region 20, It is possible to increase the number of contact pieces (second contact pieces 26) without increasing the size of the contact piece region 20 in a limited space, that is, in a direction orthogonal to the insertion direction.
Further, the pitch of the two first contact pieces 24 and one second contact piece 26 in the direction orthogonal to the insertion direction is increased without increasing the size of the contact piece region 20 in the direction orthogonal to the insertion direction. Can be secured.
Accordingly, since the pitch in the direction orthogonal to the insertion direction of the connection terminal 54 of the connector 50 can be secured with a large dimension, for example, the mechanical strength of each connection terminal 54 is ensured by increasing the cross-sectional area of the connection terminal 54. it can.
In addition, a large contact area between each connection terminal 54 and each contact piece 22 (first contact piece 24, second contact piece 26) can be secured.

The memory card 10 according to the first embodiment can be used by being attached to a connector for a conventional memory card, thereby ensuring compatibility.
FIG. 10A is an explanatory view showing a state where the memory card 10 according to the first embodiment and the conventional memory card connector 50 ′ are not coupled, and FIG. 10B is a cross-sectional view taken along the line BB of FIG.
FIG. 11A is an explanatory view showing a state in which the memory card 10 in the first embodiment and a conventional memory card connector 50 ′ are coupled together, and FIG. 11B is a sectional view taken along line BB in FIG.
As shown in FIG. 10, the connector 50 has ten connection terminals 56 that face the insertion slot 52 into which the memory card 10 is inserted and can elastically contact (contact with) each contact piece of the conventional memory card. They are arranged in a direction perpendicular to the insertion direction.
In the embodiment, the contact pieces 1 to 10 have the same pitch as the conventional memory card 10 ′ having the ten contact pieces 22 ′ shown in FIG. 19 (in the contact pieces 3, 4, 5, 6, 7, and 8. The distance between the centers in the width direction of the wide portion 2404), and the pitch of the gap S1 between the wide portions 2404 of the contact pieces 3, 4, 5, 6, 7, 8 is conventionally The memory card 10 'is formed with the same dimensions as the pitch of the partition walls 1410.
The ten connection terminals 56 can be elastically contacted (contactable) with the contact pieces 1 to 10 of the memory card 10 according to the first embodiment, but the connection terminals 56 correspond to the contact pieces 11 to 14 of the memory card 10. Is not provided.
Therefore, as shown in FIG. 11, by attaching the memory card 10 of the first embodiment to the conventional memory card connector 50 ', a 4-bit parallel connection is made only through the four contact pieces 3, 4, 7, and 8. The data signals SIDO0 to SIDO3 in the format can be input / output.
That is, when the memory card 10 according to the first embodiment is mounted on the connector of the external device that performs data communication using a data signal in a 4-bit parallel format, the total of 10 contact pieces, the contact piece 1 to the contact piece 10, are the connectors of the external device. However, the contact pieces 11 to 14 are not in contact with the connection terminals and are electrically open.
In this case, for example, 4 bits based on the fact that the control circuit of the memory card 10 detects the connection of the contact pieces 1 to 10 to the connection terminals and detects the open state of the contact pieces 11 to 14. Recognizes that data communication is performed in parallel format, and data signals are communicated in 4-bit parallel format via four contact pieces, contact piece 4, contact piece 4, contact piece 5, and contact piece 7. Is secured.

Next, Example 2 will be described with reference to the drawings.
The difference between the second embodiment and the first embodiment is that, in the first embodiment, the pattern unit of the contact pieces composed of the contact pieces 3, 11, 4, 12, and 5 is arranged between two adjacent partition walls 1410. In the second embodiment, the pattern unit including the contact pieces 6, 13, 7, 14, and 8 is disposed between two adjacent partition walls 1410. One partition wall 1410 located between the two is removed, and the two pattern units are disposed between two adjacent partition walls 1410.
12 is a perspective view of the memory card 10 according to the second embodiment as viewed from below, FIG. 13 is a bottom view of the memory card 10 according to the second embodiment as viewed from below, and FIG. 14 is a front view of the memory card 10 according to the second embodiment. It is an enlarged view. In the following description, the same members and portions as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
Similarly to the first embodiment, the memory card 10 of the second embodiment can also input / output 8-bit parallel format data signals SIDO0 to SIDO7, thereby extending the bit width of the data signal and transferring data. This is advantageous in increasing the speed.
Further, as in the first embodiment, without increasing the size of the contact piece region 20 in the direction orthogonal to the insertion direction, the two first contact pieces 24 and one second contact piece 26 are orthogonal to the insertion direction. Since the pitch in the direction to be connected can be secured with a large dimension, the pitch in the direction orthogonal to the insertion direction of the connection terminal 54 of the connector 50 can be secured with a large dimension. For example, the mechanical strength of each connection terminal 54 can be secured. A large contact area between the 50 connection terminals 54 and the contact pieces 22 (the first contact piece 24 and the second contact piece 26) can be secured.
Of course, the memory card 10 of the second embodiment can ensure compatibility so that it can be used by being attached to a connector for a conventional memory card, as in the first embodiment.

Next, modified examples of the first contact piece 24 and the second contact piece 26 will be described.
FIG. 20 is an explanatory view showing Modification 1 of the contact piece.

With this configuration, when the connector 50 is of the push-in / push-out type, that is, when the memory card 10 is inserted into the connector 50 along the insertion direction, the memory card 10 is inserted into the connector 50 and engaged, When the memory card 10 is configured to be detached from the connector 50 when the card 10 is pushed into the connector 50 along the insertion direction, the contact area of the second contact piece 26 with which the connection terminal 54B of the connector 50 contacts is in the insertion direction. The length (overstroke amount) can be ensured, which is advantageous in reliably connecting the connection terminal 54B and the second contact piece 26.

FIG. 21 is an explanatory view showing Modification 2 of the contact piece.
As shown in FIG. 21, when the pitch of the first contact piece 24 (distance between the centers of the wide portions 2404) in the direction orthogonal to the insertion direction is P1, and the pitch of the second contact piece 26 is P2. , P1 <P2 may be set. In other words, in the embodiment, the second contact piece is arranged so that the center in the width direction is on the center line of the gap between the wide portions of the two adjacent first contact pieces. The two second contact pieces 26 may be provided with a predetermined dimension offset from the center line of the gap between the wide portions of the first contact pieces in a direction away from each other in a direction orthogonal to the insertion direction.
With this configuration, the width of the width detail 2402 of one first contact piece 24 sandwiched between the two second contact pieces 26 is secured, and the first of both sides sandwiching the one first contact piece 24 is secured. It is possible to match the width of the width detail 2402 of the first contact piece 24, the width of the width detail 2402 of each first contact piece 24 can be matched, and the mechanical strength and resistance value of the first contact piece 24 can be matched. This is advantageous in setting the angle uniformly.

By the way, when the conventional memory card 10 ′ having ten contact pieces 22 ′ shown in FIG. 19 is temporarily mounted on the connector 50 for the memory card 10 of the first and second embodiments, four connections having a large length are connected.

The connection terminal 54B having a long length is inserted into the insertion slot 52 when the partition wall 1410 is formed at the location of the memory card 10 'corresponding to the connection terminal 54B having a long length. Then, the connecting terminal 54B having a large length is configured to engage with the edge portion 1420 of the partition wall 1410 and move along the edge portion 1420 (climb on the edge portion 1420) to leave the contact piece region 20. .
As described above, one connection terminal 54B comes into contact with the edge 1420 of the partition wall 1410 and retreats, thereby preventing the connection terminal 54B from being damaged.
Therefore, in the configuration example 1, the memory card 10 of the present invention can be inserted and removed, and the conventional memory card 10 'can also be removed.
