[0017] Example 1

[0018] Figure 1 This is a schematic diagram of the structure of the multi-functional adapter board provided in Embodiment 1 of the present invention. This embodiment is applicable to various functional small boards communicating with the host based on the MBIM protocol. Figure 1 As shown, the multi-functional adapter board includes: an MB-side male connector 100, a USB signal cable 110, a PCIe signal cable 120, a first detection control signal cable 130, a second detection control signal cable 140, a first universal Type-C interface 210, a second universal Type-C interface 220, a first power cable 150, a second power cable 160, a first ground cable 170, and a second ground cable 180. The MB-side male connector 100 is connected to the first universal Type-C interface 210 via the USB signal cable 110, the first detection control signal cable 130, the first power cable 150, and the first ground cable 170, and is connected to the second universal Type-C interface 220 via the PCIe signal cable 120, the second detection control signal cable 140, the second power cable 160, and the second ground cable 180, for connection to the MB-side female connector. The first universal Type-C interface 210 and the second universal Type-C interface 220 are used to connect to the Type-C interface function board.

[0019] Specifically, the MB (Mobile Broadband) male connector 100 can connect to the MB female connector inside the host, enabling communication between the MBIM interface and the host using the data format specified by the MBIM protocol. Optionally, the MB female connector is pre-connected to the host's USB signal, PCIe signal, detection control signal, power signal, and ground signal. The MB male connector 100 is used to transfer each signal to the corresponding universal Type-C interface using the respective signal lines. Specifically, before using the multi-functional adapter board provided in this embodiment, the above signals can be pre-connected from the host to the MB female connector during the design phase. Then, after the MB male connector 100 and the MB female connector are matched and connected, the MB male connector 100 can transfer the above signals to the corresponding universal Type-C interface through the aforementioned signal lines. Specifically, the USB signal can be transferred to the first general-purpose Type-C interface 210 via the USB signal cable 110, where the USB signal may include USB 2.0 signal and / or USB 3.0 signal; the PCIe signal can be transferred to the second general-purpose Type-C interface 220 via the PCIe signal cable 120; the USB-related signals in the detection and control signals can be transferred to the first general-purpose Type-C interface 210 via the first detection and control signal cable 130; and the PCIe-related signals in the detection and control signals can be transferred to the second general-purpose Type-C interface 220 via the second detection and control signal cable 140, and so on.

[0020] The USB signal line 110, PCIe signal line 120, first detection control signal line 130, and second detection control signal line 140 can each be multiple. For example, the USB signal can include: USB2_C1_8P, USB2_C1_8P, USB3_C1_RX4P, USB3_C1_RX4N; the PCIe signal can include: PCIe_C1_RX11P, PCIe_C1_RX11N, PCIe_C1_TX11N, PCIe_C1_TX11P; the detection control signal converted by the first detection control signal line 130 can include: EXT_WWAN_WAKE_UP#, EXT_WWAN_5V_ON, EXT_WWAN_5V_ON_PCH; and the detection control signal converted by the second detection control signal line 140 can include: EXT_I2C_SEL, EXT_WWAN_CARD_DET#, EXT_5G_PD_OC#, etc.

[0021] Optionally, the power signal includes a 3V power signal and a 5V power signal; the 3V power signal is transferred to the second universal Type-C interface 220 through the second power line 160, and the 5V power signal is transferred to the first universal Type-C interface 210 through the first power line 150, so as to provide different power supplies to the outside through the two universal Type-C interfaces respectively.

[0022] Optionally, the functional board includes various customized functional boards designed according to user needs, based on the interface signal definitions of the first universal Type-C interface 210 and the second universal Type-C interface 220. Specifically, after fixing the signals of the first universal Type-C interface 210 and the second universal Type-C interface 220 based on the above, different functional boards can be designed according to actual user needs and the signal definitions of the two universal Type-C interfaces. These functional boards can then be connected to the multi-function adapter board via the two universal Type-C interfaces, and further communicate with the host via the MBIM interface to achieve different functions and meet the needs of different customers.

[0023] Based on the above technical solution, optionally, the multi-functional adapter board further includes a first PCB substrate; both the first universal Type-C interface 210 and the second universal Type-C interface 220 are perpendicularly arranged to the first PCB substrate. Specifically, since the interface direction on a typical host is horizontal, by arranging the two universal Type-C interfaces perpendicularly to the first PCB substrate, the connection between the subsequent functional board and the multi-functional adapter board can be made more stable.

[0024] Optionally, the functional board includes a second PCB substrate, and a first target Type-C interface and a second target Type-C interface that are respectively matched and connected to the first universal Type-C interface 210 and the second universal Type-C interface 220. Both the first target Type-C interface and the second target Type-C interface are arranged parallel to the second PCB substrate. That is, based on the fact that the two universal Type-C interfaces in the aforementioned multi-functional adapter board are perpendicular to the first PCB substrate, by arranging the two correspondingly matched target Type-C interfaces in the functional board parallel to the second PCB substrate, the stability of the connection between the functional board and the multi-functional adapter board can be further improved.

[0025] The multi-functional adapter board provided in this invention includes an MB-end male interface connector, a USB signal cable, a PCIe signal cable, a first detection control signal cable, a second detection control signal cable, a first universal Type-C interface, a second universal Type-C interface, a first power cable, a second power cable, a first ground wire, and a second ground wire. By using various signal cables, the signals input from the MB-end male interface connector are converted to the universal Type-C interface, and then connected to the functional board using the universal Type-C interface. To meet the different needs of different customers, only different functional boards need to be designed according to customer requirements, without requiring design changes to the MBIM. This saves costs and simplifies the design while satisfying different customer needs.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
