Through the above method, a detection contact can be added to be specifically used for identifying the memory card, avoiding the hidden danger of system failure caused by instability caused by the prior art of identifying the memory card by sending instructions by software, and can quickly identify the memory card.

[0044] The present application is described below through an example of a NM card (Nano memory card).

[0050] See also Figure 5 , Figure 5 1 is a schematic diagram of the structure of the third embodiment of the memory card provided by the present application. The memory card 10 of this embodiment includes a package board 11 and a plurality of contact pads (not shown) disposed on one side of the package board 11.

[0053] In addition, the fourth data contact pad (D2) includes an extension portion, and extends to the outside of the power contact pad (VCC).

[0054] See also Figure 6 , Figure 6 1 is a schematic diagram of the structure of the fourth embodiment of the memory card provided by the present application. The memory card 10 of this embodiment includes a package board 11 and a plurality of contact pads (not shown) disposed on one side of the package board 11.

[0055] The eight contacts are distributed in a matrix of four rows and two columns; the contacts located in the first column of the matrix are the first data contact, the command contact, the ground contact, and the third data contact, which correspond to the D1 pin, CMD pin, GND pin, and D3 pin of the EMMC protocol respectively; the contacts located in the second column of the matrix are the clock contact, the second data contact, the power supply contact, and the fourth data contact, which correspond to the CLK pin, D0 pin, VCC pin, and D2 pin of the EMMC protocol respectively.

The second detection contact piece 12d is spaced apart from the power supply contact piece 12a and the fourth data contact piece (D2) adjacent to the second detection contact piece 12d along the length direction of the memory card, and is located on the outside of the power supply contact piece 12a and the fourth data contact piece (D2).

[0057] In addition, the third data contact (D3) includes an extension portion, and extends to the outside of the ground contact 12b.

[0058] See also Figure 7 , Figure 7 1 is a schematic diagram of the structure of the fifth embodiment of the memory card provided by the present application. The memory card 10 of this embodiment includes a package board 11 and a plurality of contact pads (not shown) disposed on one side of the package board 11. In this embodiment, the plurality of contact pads includes ten contact pads in total.

[0059] The eight contacts are distributed in a matrix of four rows and two columns; the contacts located in the first column of the matrix are the first data contact, the command contact, the ground contact, and the third data contact, which correspond to the D1 pin, CMD pin, GND pin, and D3 pin of the EMMC protocol respectively; the contacts located in the second column of the matrix are the clock contact, the second data contact, the power supply contact, and the fourth data contact, which correspond to the CLK pin, D0 pin, VCC pin, and D2 pin of the EMMC protocol respectively.

[0060] In addition, the ninth contact is the first detection contact 12c, and the grounding contact 12b and the third data contact (D3) adjacent to the first detection contact 12c are spaced apart along the width direction of the memory card. The first detection contact 12c is spaced apart from the grounding contact 12b and the third data contact (D3) adjacent to the first detection contact 12c along the length direction of the memory card, and is located on the outside of the grounding contact 12b and the third data contact (D3).

[0061] In addition, the tenth contact piece is the second detection contact piece 12d, and the power supply contact piece 12a and the fourth data contact piece (D2) adjacent to the second detection contact piece 12d are spaced apart along the width direction of the memory card. The second detection contact piece 12d is spaced apart from the power supply contact piece 12a and the fourth data contact piece (D2) adjacent to the second detection contact piece 12d along the length direction of the memory card, and is located on the outside of the power supply contact piece 12a and the fourth data contact piece (D2).

[0062] In addition, only one of the first detection contact piece 12c and the second detection contact piece 12d may be used for detection, while the other may be used for other functions, for example, as a data contact piece, a command contact piece, a reset contact piece, etc.

[0063] In addition, the above embodiments describe the pins of the NM card corresponding to the MMC protocol. It can be understood that the above embodiments are not only applicable to the MMC protocol, but also to the SD protocol, UFS protocol, USB protocol, etc.

[0064] contrast Figure 3 and Figure 5-7 The external dimensions of the packaging board of the NM card in this embodiment match those of the SIM card, and the same connector can be reused with the SIM card.

[0065] Specifically, the length, width and thickness of the packaging board are 12.3 mm, 8.8 mm and 0.7 mm respectively, and one corner of the packaging board is provided with a bevel.

[0066] Optionally, in one embodiment, the bevel angle is 45°, and the width of the bevel angle is 1.65 mm.

[0067] It is understandable that in other embodiments, other corners of the package board or the corners of each contact piece may be beveled or rounded as required, which is not limited here.

[0068] Among them, combined Figure 3 and Figure 5 When the NM card and the SIM card overlap, the first detection contact piece 12c of the NM card and the ground contact piece 12b adjacent to the first detection contact piece 12c are at least partially located within the projection area of ​​the ground contact piece (GND) corresponding to the SIM card.

[0069] Among them, combined Figure 3 and Figure 6 When the NM card and the SIM card overlap, the second detection contact piece 12d of the NM card and the power supply contact piece 12a adjacent to the second detection contact piece 12d are at least partially located within the projection area of ​​the power supply contact piece (GND) corresponding to the SIM card.

[0070] Among them, combined Figure 3 and Figure 7 When the NM card and the SIM card overlap, the first detection contact piece 12c of the NM card and the grounding contact piece 12b arranged adjacent to the first detection contact piece 12c are at least partially located within the projection area of ​​the grounding contact piece (GND) corresponding to the SIM card, and the second detection contact piece 12d of the NM card and the power supply contact piece 12a arranged adjacent to the second detection contact piece 12d are at least partially located within the projection area of ​​the power supply contact piece (GND) corresponding to the SIM card.

[0071] The purpose of the above arrangement is that when two contact terminals are used to contact an NM card, they can contact the detection contact and the power supply contact / ground contact respectively, and when the same two contact terminals are used to contact a SIM card, they can contact the power supply contact or the ground contact at the same time to facilitate subsequent card identification.

[0072] See also Figure 8 and Fig. 9 , Figure 8 is a three-dimensional structural diagram of an embodiment of a connector provided by the present application, Fig. 9 It is a front view structural schematic diagram of an embodiment of a connector provided in the present application.

[0073] The connector 80 includes a plurality of contact terminals (not shown); wherein the plurality of contact terminals include a power supply terminal 82a, a ground terminal 82b and a detection terminal (82c and / or 82d), wherein when Figure 1 , 2 When the memory card 10 of , 5, 6, 7 is mated with the connector 80, the detection terminal and the power supply terminal or the ground terminal are respectively in contact with the detection contact on the memory card and the power supply contact or the ground contact arranged adjacent to the detection contact.

[0074] Optionally, in one embodiment, the detection terminal specifically includes a first detection terminal 82c and a second detection terminal 82d.

[0075] Specifically, Figure 3 For example, when the SIM card is mated with the connector 80, the power contact VCC of the SIM card is in contact with the power terminal 82a and the second detection terminal 82d at the same time, and the ground contact GND of the SIM card is in contact with the ground terminal 82b and the first detection terminal 82c at the same time.

[0076] Specifically, Figure 5 For example, when the NM card is mated with the connector 80, the power contact piece 12a contacts the power terminal 82a, the ground contact piece 12b contacts the ground terminal 82b, and the first detection contact piece 12c contacts the first detection terminal 82c.

[0077] Specifically, Figure 6 For example, when the NM card is mated with the connector 80, the power contact piece 12a contacts the power terminal 82a, the ground contact piece 12b contacts the ground terminal 82b, and the second detection contact piece 12d contacts the second detection terminal 82d.

[0078] Specifically, Figure 7 For example, when the NM card is mated with the connector 80, the power contact 12a contacts the power terminal 82a, the ground contact 12b contacts the ground terminal 82b, the first detection contact 12c contacts the first detection terminal 82c, and the second detection contact 12d contacts the second detection terminal 82d.

[0079] Therefore, when the connector 80 is used to identify the memory card provided in this embodiment, it is possible to detect whether the potentials of the power supply terminal 82a and the second detection terminal 82d are the same. If they are the same, the card to be identified is identified as a SIM card; if they are different, the card to be identified is identified as the memory card of this embodiment. Alternatively, it is possible to detect whether the potentials of the ground terminal 82b and the first detection terminal 82c are the same. If they are the same, the card to be identified is identified as a SIM card; if they are different, the card to be identified is identified as the memory card of this embodiment.

[0080] Optionally, there are multiple detection terminals, and the multiple detection terminals respectively correspond to detection contact pieces of multiple different types of function cards, so as to identify different types of function cards according to detection conditions of different detection terminals.

[0081] For example, the connector may include two detection terminals, and the two detection terminals may be arranged to correspond to detection contacts of two different types of memory cards. Specifically, the first detection terminal corresponds to a first type of memory card, and the second detection terminal corresponds to a second type of memory card. When identifying the memory card, if the first detection terminal detects a set electrical signal, the memory card is identified as a first type of memory card, and if the second detection terminal detects a set electrical signal, the memory card is identified as a second type of memory card.

[0082] In addition, combined Figure 4 NM card and Figure 5-7 The NM card provided in this embodiment also has the following advantages:

[0083] 1. In Figure 4 In the embodiment, the D2 and D3 pins are both data I / O and cannot be used to identify the hardware status; the 6 pins (i.e., D1, CMD, GND, CLK, D0, VCC) reused by the NM card and the SIM card have similar functions and cannot be used to identify the hardware status; the NM card provided in this embodiment adds a new test pin, which solves the problem that the D2 and D3 pins cannot be used for identification.

[0084] 2. The software recognition that uses the invented command to obtain the card's response is unreliable, and it is easy to communicate without good contact, resulting in system failure. In addition, the working voltage of the NM card is 1.8V or 3.3V, while the working voltage of the SIM card is 1.8V or 3V. There is a voltage switch during the software recognition process. If there is a recognition error, it is easy to use an incorrect voltage to operate the memory card or SIM card, which poses a potential risk.

[0085] 3. Figure 4 The D2 and D3 pins in the embodiment are too long, which increases the risk of short circuit with VCC and GND. However, this embodiment solves this problem by changing the pins.

[0086] See also Fig.10 , Fig.10 1 is a flow chart of a first embodiment of a method for identifying a function card provided by the present application, the method comprising:

[0087] Step 101: Power on the memory card to be identified using the power supply terminal of the connector.

[0088] It is understandable that, since the terminals of the connector are relatively fixed, it can only be powered on by inserting a matching function card. For example, the connector in this embodiment is suitable for NM cards, SIM cards, and other cards with similar contact layouts.

[0089] Specifically, the power supply terminal of the connector contacts the power supply contact piece of the function card, and the ground terminal of the connector contacts the ground contact piece of the function card.

[0090] Step 102: Determine whether the detection terminal of the connector detects an electrical signal.

[0091] Step 103: Identify the function card as a memory card or a SIM card according to the detection result of the detection terminal.

[0092] It can be understood that based on the structure of the NM card, SIM card and connector provided in the above embodiments, the detection terminal corresponds to the detection contact of the NM card, and the power supply contact or ground contact of the SIM, so identification can be performed based on the difference between the electrical signals of the detection contact and the power supply contact and ground contact.

[0093] See also Fig.11 , Fig.11 : is a flow chart of a second embodiment of a method for identifying a function card provided by the present application, the method comprising:

[0094] Step 111: Power on the memory card to be identified using the power supply terminal of the connector.

[0095] Step 112: Determine whether the detection terminal of the connector detects an electrical signal.

[0096] If no electrical signal is detected, step 113 is executed; if an electrical signal is detected, step 114 is executed.

[0097] Step 113: Identify the function card as a target memory card.

[0098] Step 114: Determine whether the electrical signal detected by the detection terminal is the same as the electrical signal detected by one of the power supply terminal and the ground terminal of the connector that is disposed adjacent to the detection terminal.

[0099] If they are the same, execute step 115; if they are not the same, execute step 116.

[0100] Step 115: Identify the function card as a SIM card.

[0101] Step 116: Identify the function card as a target memory card.

[0102] In one embodiment, in an embodiment where the detection contact corresponding to the detection terminal is not connected to the power supply contact or the ground contact, the detection contact is equivalent to being suspended, and the detection terminal does not detect any electrical signal at this time.

[0103] In another embodiment, the memory card may not be provided with any contact piece at the position corresponding to the detection terminal. In this case, the detection terminal cannot detect any electrical signal and will identify the function card as the target memory card.

[0104] In addition, in the embodiment where the detection contact is adjacent to the power supply contact, if it is a SIM card, the potentials of the detection terminal and the power supply terminal should be the same, while in the memory card, because the detection contact is connected to the ground contact, the potentials of the detection terminal and the power supply terminal are opposite.

[0105] Similarly, in the embodiment where the detection contact is adjacent to the ground contact, if it is a SIM card, the potentials of the detection terminal and the power supply terminal should be the same, while in the memory card, because the detection contact is connected to the power supply contact, the potentials of the detection terminal and the power supply terminal are opposite.

[0106] Therefore, by judging whether the potential of the detection contact piece is the same as that of the power supply contact piece, or whether the potential of the detection contact piece is the same as that of the ground contact piece, the SIM card and the memory card can be identified.

[0107] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
