(not shown), the card cover 11 is provided on the motherboard 10, and the card cover 11 is grounded. There is a mounting slot 10a between the card cover 11 and the motherboard 10. The mounting slot 10a is used to install the card holder or external fixture, and connect electrical components. 12 is provided on the motherboard 10, the power-connecting component 12 is located in the installation slot 10a, and the power-connecting component 12 is electrically connected to the programming interface;

Among them, when the installation slot 10a is installed with a card tray, the motherboard 10 is used to electrically connect to the SIM card carried by the card tray. When the installation slot 10a is installed with an external fixture, the card cover 11 is used to electrically connect to the external fixture. 12 is used for electrical connection to external fixtures.

In this embodiment, a card cover 11 is provided on the motherboard 10 . A mounting slot 10 a is provided between the card cover 11 and the motherboard 10 for installing a card tray or an external fixture. The motherboard 10 is also provided with a power connector 12 and a programming interface of the motherboard 10 Electrical connection, and the card cover 11 is grounded. In this way, when the card tray is installed in the installation slot 10a, the motherboard 10 is electrically connected to the SIM card carried by the card tray. At this time, the SIM card can communicate with the motherboard 10. When the external fixture is installed in the mounting slot 10a, the external fixture is electrically connected to the card cover 11 and the electrical connection part 12. At this time, the external fixture is used to transmit the low-level signal for grounding the card cover 11 to the electrical connection part 12. The programming interface of the motherboard 10 can cause the motherboard 10 to enter forced programming after receiving a low-level signal. When the motherboard assembly 100 is applied to a smart wearable device, there is no need to set an additional programming button, and the smart wearable device can implement forced burning. Recording is less difficult.

Moreover, in this embodiment, the motherboard assembly 100 is designed so that the SIM card can be used normally by installing the card holder in the mounting slot 10a. When the motherboard assembly 100 needs to be forced to burn, the SIM card can be detached from the mounting slot 10a and used externally. The jig replaces the card tray so that the programming interface of the motherboard 10 receives low-level signals for forced programming, thereby realizing structural reuse. The overall structure of the motherboard assembly 100 is relatively simple, and there is no need to add additional sockets or installation slots 10a and other structures. For installing external fixtures.

Among them, the card holder can be made of insulating materials, such as plastic, rubber, etc., and the external fixture can be made of conductive materials or its surface can be coated with conductive materials, such as copper, aluminum and other metal materials or metal alloys.

In some embodiments, the card cover 11 is provided with a connecting portion 111. When an external fixture is installed in the mounting groove 10a, the connecting portion 111 is used to contact the external fixture to make contact and conduction with the external fixture. In this way, when the external fixture is installed in the mounting groove 10a, the external fixture can abut against the connecting portion 111 to be in contact with the connecting portion 111, so that the low-level signal for grounding the card cover 11 can be transmitted through the electrically connected component 12 to the programming interface of the motherboard 10. After the programming interface receives a low-level signal, the motherboard 10 can enter forced programming.

For example, when the mounting slot 10a is installed with an external fixture, the connecting portion 111 is also used to abut the external fixture to fix the external fixture along the first direction x. When the mounting slot 10a is installed with a card holder, the connecting portion 111 is used. It is in contact with the card tray to fix the card tray along the first direction x, where the first direction x is the insertion direction of the mounting groove 10a for installing the card tray or an external fixture. In this way, when the external fixture is inserted into the installation groove 10a along the first direction connection, so that the low-level signal that grounds the card cover 11 can be transmitted to the programming interface of the motherboard 10 through the electrical connector 12. After the programming interface receives the low-level signal, the motherboard 10 can enter forced programming. On the other hand, , the connection part 111 can fix the external fixture and the card cover 11 to each other along the first direction Invalid, resulting in burning failure. Moreover, when the motherboard assembly 100 is not forced to burn, the card tray can be installed in the installation slot 10a to electrically connect the SIM card carried by the card tray to the motherboard 10 to realize communication between the SIM card and the motherboard 10. At this time, the connecting portion is used 111 can fix the card tray and the card cover 11 to each other along the first direction situation occurs.
