The demand of domestic users for SD cards is weak, and therefore the related art provides a terminal device whose card socket includes a compatible card slot and a single card slot. The compatible card slot can be used for installing an SD card or a SIM card. However, the demand of the foreign users such as india for SD is strong, and thus the related art also provides another terminal device whose card socket includes three single card slots. Wherein, three single card grooves include two SIM card grooves and an SD card groove respectively.

In order to match different card seats, different circuit boards are needed to be configured for two kinds of terminal equipment with domestic and foreign durations. This increases the hardware and terminal equipment costs.

Based on the above problem, the embodiments of the present disclosure provide an electronic device and a terminal device.

In a first aspect, embodiments of the present disclosure provide an electronic device. FIG. 1 is a block diagram illustrating an electronic device according to an exemplary embodiment.

As shown in fig. 1, an electronic device provided by an embodiment of the present disclosure includes: a circuit board 100, a single socket interface 110, a multiple socket interface 120, and a processor 200 disposed on the circuit board 100.

The single socket interface 110 mates with an external card (e.g., a SIM card). And, the single card socket interface 110 is electrically connected to the processor 200 through a resistor.

The multi-card socket interface 120 includes a compatible card socket interface 121 and a single card socket interface 122. The compatible card slot interface 121 includes a first card slot interface 121a electrically connected to the processor 200 through a resistor, and a second card slot interface 121b electrically connected to the processor. The compatible card slot interface 121 mates with two external card components (e.g., a SIM card and a memory card). Single card slot interface 122 is in direct electrical communication with processor 200 and mates with an external card (e.g., a SIM card).

Wherein, the single card socket interface 110 and the compatible card socket interface 121 are electrically connected to the processor 200 through a resistor, that is: with the resistor removed, the single card socket interface 110 and the compatible card slot interface 121 are electrically disconnected from the processor 200.

The electronic device provided by the embodiment of the disclosure has the following use modes:

a resistor electrically connecting the first card slot interface 121a and the processor 200 is disposed on the circuit board 100, and a resistor electrically connecting the single card slot interface 110 and the processor 200 is not disposed. In this manner, multiple card sockets are supported on the circuit board 100. At the moment, the electronic device is provided with two card slots, and a compatible card slot (compatible with the SIM card and the memory card) can be installed to be matched with one SIM card slot, so that the domestic user requirements are met.

A resistor electrically connecting the single card socket interface 110 and the processor 200 is disposed on the circuit board 100, and a resistor electrically connecting the first card slot interface 121a and the processor 200 is not disposed. In this way, it is supported that a single card socket and a plurality of card sockets are provided on the circuit board 100, and the card socket interface 121 compatible with the plurality of card sockets supports a card adapted to the second card socket interface 121 b. At this time, the electronic device has three card slots, and can be provided with two SIM card slots and one SD card slot, so that the requirements of foreign users are met.

In summary, the electronic device provided in the embodiment of the present disclosure uses the same circuit board to support two card sockets, so as to meet two user requirements and reduce the hardware cost of the terminal device.

In one embodiment, as shown in FIG. 1, the processor 200 includes a first test pin 210 and a second test pin 220 electrically connected by a resistor. The multi-socket interface 120 further includes a third test pin 123 electrically connected to the first test pin 210. The single socket interface 110 includes a fourth detection pin 111 electrically connected to the second detection pin 220 through a resistor.

Based on different card seat realization modes supported by the electronic device, the detection pin in the electronic device has two setting modes:

in the first mode, the electronic device supports a single card holder and multiple card holders. Specifically, the single card socket interface 110 and the processor 200 are electrically connected through a resistor, and the first card slot interface 121a is electrically disconnected from the processor 200. At this time, the second and fourth detection pins 220 and 111 are electrically connected through a resistor, and the first and second detection pins 210 and 220 are disconnected.

Second, the electronic device only supports multiple sockets. Specifically, the first card slot interface 121a and the processor 200 are electrically connected through a resistor, and the single card slot interface 110 and the processor 200 are electrically disconnected. The first detection pin 210 and the second detection pin 220 are electrically connected through a resistor.

In other words, in an electronic device supporting a card socket implementation, the first detection pin 210 is electrically connected with the second detection pin 220; in an electronic device supporting another card socket implementation, the first detection pin 210 is electrically disconnected from the second detection pin 220. Based on this, the processor determines the current card socket implementation mode supported by the electronic device by judging the electrical connection condition of the first detection pin 210 and the second detection pin 220.

In one embodiment, the first card slot interface 121a of the multiple card slot interface 120 compatible with the card slot interface 121 is a SIM card interface, and the second card slot interface 121b is a memory card interface (e.g., an SD card). The single card slot interface 122 in the multi-card-holder interface 120 is a SIM card interface. The single socket interface 110 is a SIM card interface.

As shown in fig. 1, the processor 200 includes a first SIM card interface 230. The first SIM card interface 230 includes: a first clock signal pin 231, a first reset pin 232, and a first data pin 233.

The first card slot interface 121a of the compatible card slot interface 121 includes: a second clock signal pin 1211, a second reset pin 1212, and a second data pin 1213.

The second clock signal pin 1211 is electrically connected to the first clock signal pin 231 through a resistor, so as to transmit a clock signal between the external card and the processor 200. The second reset pin 1212 is electrically connected to the first reset pin 232 through a resistor, so as to implement the transmission of the reset signal between the external card and the processor 200. The second data pin 1213 is electrically connected to the first data pin 233 through a resistor, so that data signal transmission between the external card and the processor 200 is realized.

The single socket interface 110 includes: a third clock signal pin 112, a third reset pin 113, and a third data pin 114.

The third clock signal pin 112 is electrically connected to the first clock signal pin 231 through a resistor, so as to transmit a clock signal between the external card and the processor 200. The third reset pin 113 is electrically connected to the first reset pin 232 through a resistor, so that the transfer of a reset signal between the external card and the processor 200 is realized. The third data pin 114 is electrically connected to the first data pin 233 through a resistor, so that data signal transmission between the external card and the processor 200 is realized.

Further, the processor 200 comprises a first interface 240 and a second interface 250. The first interface 240 is a memory card interface (e.g., an SD card interface), and the second interface 250 is a SIM card interface. The second card slot interface 121b of the compatible card slot interface 121 of the multi-card holder interface 120 is electrically connected to the first interface 240, and the single card slot interface 122 of the multi-card holder interface 120 is electrically connected to the second interface 250.

In a second aspect, an embodiment of the present disclosure further provides a terminal device. Fig. 2 is a schematic diagram illustrating a partial structure of a terminal device according to an exemplary embodiment.

As shown in fig. 2, the terminal device includes: a first resistor 300, a single socket 400, a multi-socket 500, and the electronic device provided by the first aspect above.

The single card socket 400 is disposed on the circuit board 100 corresponding to the single card socket interface 110, and the first resistor 300 is electrically connected to the single card socket interface 110 and the processor 200.

The multi-card socket 500 is disposed on the circuit board 100 at a position corresponding to the multi-card socket interface 120. The multi-card socket 500 includes a compatible card slot 510 and a single card slot 520, where the compatible card slot 510 is disposed corresponding to the compatible card slot interface 121, and the single card slot 520 is disposed corresponding to the single card slot interface 122.

It should be noted that, in this embodiment, no resistor is provided between the first card slot interface 121a of the compatible card slot interface 121 and the processor 200. That is, the first card slot interface 121a is electrically disconnected from the processor 200. However, the second card slot interface 121b is directly electrically connected to the processor 200. In this way, the terminal device provided by the embodiment of the disclosure can be provided with three card slots to install three external cards.

In one embodiment, the processor 200 of the electronic device includes a first detect pin 210 and a second detect pin 220; the single socket interface 110 includes a fourth test pin 111, and the multi-socket interface 120 includes a third test pin 123. The second detection pin 220 and the fourth detection pin 111 are electrically connected through a first resistor 300.

In this way, when an external card is inserted into the single card socket 400, the fourth detection pin 111 is triggered to send an interrupt signal to the second detection pin 220. Further, the processor performs power-on detection of the single card socket interface based on the received interrupt signal to determine whether an external card is inserted into the single card socket 400.

Also, the third detection pin 123 is directly electrically connected to the first detection pin 210 of the processor. In this way, when an external card is inserted into the multi-card socket 500, the third detection pin 123 is triggered to send an interrupt signal to the first detection pin 210. Further, the processor performs power-on detection of the single card slot interface and power-on detection of the second card slot interface based on the received interrupt signal to determine whether an external card is inserted into the single card slot 520 and the compatible card slot 510.

In addition, when the terminal device is used, the processor 200 first detects whether the first detection pin 210 is connected to the second detection pin 220, and if it is detected that the first detection pin 210 is electrically disconnected from the second detection pin 220, it indicates that the electronic device supports three external cards currently.

In the embodiment of the present disclosure, the single socket interface 110 is a SIM card interface. In the multi-card socket 500, the single-card-slot interface 122 is a SIM card interface, and the second card-slot interface 121b compatible with the card-slot interface 121 is a memory card interface. And, the terminal device further includes: a first SIM card installed in single card socket 400, a memory card installed in compatible card slot 510, and a second SIM card installed in single card slot 520.

In summary, the terminal device provided by the embodiment of the present disclosure supports two SIM cards and one SD card, and meets the user requirements.

In a third aspect, an embodiment of the present disclosure provides a terminal device. Fig. 3 is a schematic structural diagram of a terminal device shown according to an exemplary embodiment.

As shown in fig. 3, the terminal device includes: the second resistor 600, the multi-card socket 500, and the electronic device provided by the first aspect.

The multi-card socket 500 is disposed on the circuit board 100 of the electronic device and includes a compatible card slot 510 and a single card slot 520. The compatible card slot 510 is disposed on the circuit board 100 corresponding to the compatible card slot interface 121, and the single card slot 520 is disposed on the circuit board 100 corresponding to the single card slot interface 122. The second resistor 600 electrically connects the processor 200 with the first card slot interface 121a of the compatible card slot interfaces 121.

In addition, since a single socket is not provided in this embodiment, no resistor is provided between the single socket interface 110 and the processor 200. That is, the single socket interface 110 is electrically disconnected from the processor 200. In this way, the terminal device provided by the embodiment of the disclosure can be provided with two card slots to mount two external cards.

In one embodiment, the processor 200 of the electronic device includes a first detect pin 210 and a second detect pin 220. The terminal device further includes a third resistor 700 electrically connecting the first sensing pin 210 and the second sensing pin 220. Also, the first detection pin 210 is directly electrically connected to the third detection pin 123.

In addition, since the single socket is not provided, no resistor is provided between the fourth detection pin 111 of the single socket interface 110 and the second detection pin 220 of the processor. That is, the fourth detection pin 111 is electrically disconnected from the second detection pin 220.

In this way, when an external card is inserted into the multi-card socket 500, the third detection pin 123 is triggered to send an interrupt signal to the first detection pin 210. Further, the processor performs power-on detection of the compatible card slot interface and power-on detection of the single card slot interface based on the received interrupt signal to determine whether an external card is inserted into the compatible card slot 510 and the single card slot 520.

In addition, when the terminal device is in use, the processor 200 first detects whether the first detection pin 210 is connected to the second detection pin 220. If the first detection pin 210 and the second detection pin 220 are detected to be electrically connected, it is indicated that the electronic device supports two external cards at present.

Alternatively, the processor 200 determines whether the first detection pin 210 is electrically connected to the second detection pin 220 by changing a level value of the second detection pin 220 and determining whether the level value of the first detection pin 210 is changed according to the level value of the second detection pin 220.

For example, in the initialization phase, the second detection pin 220 is set to output low level, and the first detection pin 210 is set to input weak pull-up. At this time, it is determined whether the first detection pin 210 is at a low level. If yes, the second detection pin 220 is controlled to input a weak pull-up, and it is determined again whether the first detection pin 210 is at a high level. If yes, it indicates that the first test pin 210 is electrically connected to the second test pin 220. The judgment accuracy is improved through two judgments, and the use safety of the terminal equipment is guaranteed.

Further, after determining that the first detection pin 210 is electrically connected to the second detection pin 220, the processor 220 disables the second detection pin 220 and only the first detection pin 210 remains. By adopting the mode, the influence of the fault of the second detection pin 210 on the performance of the processor in the use process is avoided, and the use safety of the electronic device is guaranteed.

In one embodiment, in the multi-card socket 500, the first card slot interface 121a and the single card slot interface 122 of the compatible card slot interface 121 are SIM card interfaces, and the second card slot interface 121b of the compatible card slot interface 121 is a memory card interface. At this time, the terminal device further includes: a first SIM card or memory card (e.g., an SD card) mounted on compatible card slot 510, and a second SIM card mounted on single card slot 520.

In summary, the terminal device provided in the embodiment of the present disclosure supports one SIM card and one SD card, or supports two SIM cards, so as to meet the user requirements.
