This application discloses data transmission that includes: dividing to-be-transmitted content into a plurality of data units at a session layer; transmitting the data units to the target terminal device by using a first transmission channel as a responsible channel of the to-be-transmitted content; distributing, by the session layer in a case that the session layer switches the responsible channel of the to-be-transmitted content from the first transmission channel to a second transmission channel with a different transmission protocol, the data units to the second transmission channel; and transmitting the data units distributed by the session layer to the target terminal device through the second transmission channel. In data transmission in this application, the session layer controls switching of the channels and distribution of the data units, so that the transmission sequence is free from constraints of protocols and the degree of freedom in data transmission is increased.

Data transmission method and apparatus, server, storage medium, and program product

The present invention discloses a structure for sharing card slot space. The structure includes a housing. A first card slot and a second card slot are disposed inside the housing. The insertion port of the first card slot is disposed opposite the insertion port of the second card slot. A common space is disposed between the first card slot and the second card slot. A groove is disposed inside the housing of the common space. A stopper is disposed inside the groove. The stopper can slide in the groove between the first card slot and the second card slot and is configured to prevent a card corresponding to the second card slot from being inserted into the first card slot or to prevent a card corresponding to the first card slot from being inserted into the second card slot.

Foolproof structure for sharing card slot space

A universal serial bus (USB) connector and an electronic device including the USB connector are disclosed. The USB connector includes a USB head, a printed circuit board (PCB), and a shell element, where the USB head includes an insulation plastic core and a metal housing; a conductive layer is arranged on the surface of the PCB, the PCB is assembled inside the USB head and the PCB and the USB head are mutually positioned; and the USB head and the PCB are fastened at the shell element by using a fastening member, and the metal housing is pressure-welded on the conductive layer on the surface of the PCB. The USB connector has improved structural strength and enhanced grounding reliability, and can also achieve product miniaturization and cost reduction.

USB connector and electronic device

The embodiments of the present disclosure provide a user device, which includes a main body part, a movable part electrically connected with the main body part, and a switching control unit and a rotation driver unit for co-axially connecting the main body part with the movable part. The switching control unit is used for eliminating a friction that enables the main body part to be fixed relative to the movable part fixed to turn on a rotation mode of the movable part. The rotation driver unit is used for applying a pre-pressing elastic force to the movable part when the switching control unit turns on the rotation mode of the movable part, so as to enable the movable part to automatically rotate relative to the main body part. The pre-pressing elastic force is less than the friction.

User device

Embodiments of the present invention disclose a wireless Internet device. The wireless Internet device includes a device body () with an accommodation space, a connection interface () set in the accommodation space, and a subscriber identity module (SIM) card holder () configured to install a SIM card, where a push-locking apparatus () is also set in the accommodation space; the push-locking apparatus () includes a push part () and a locking part (); the push part () is connected to the locking part (). The solution provided in the embodiments of the present invention can achieve a purpose that the SIM card holder () cannot be randomly plugged in and out when the wireless Internet device works.

Wireless internet device

The utility model provides a data card that includes a circuit board, a holder, an upper cover, a connecting wire, and an interface. The circuit board is fixed in the holder. One end of the flexible connecting wire is connected with the circuit board, and the other end of the flexible connecting wire is connected with the interface. The upper cover covers the holder. When the data card is idle, the interface and the flexible connecting wire are located in the cavity formed by the upper cover and the holder. When the data card is connected with an external device by the interface, the interface is located outside the cavity formed by the upper cover and the holder. The data card enables flexible adjustment of the location of the interface, and fixes the upper cover on the data card when the data card is connected for use.

Data card

The invention relates to communications technologies and discloses a rotation axis, a digital device and a Universal Serial Bus (USB) device. The rotation axis includes a sleeve, an elastic body, an indented washer, and a movable support. The sleeve includes a lip and a cylinder. The elastic body, the indented washer, and the movable support are configured sequentially around the cylinder with the lip adjacent to the elastic body along the axial direction of the cylinder beginning with the lip. A number of concave indents are configured on one end-surface of the indented washer and distributed on a circle. The end-surface of the indented washer where the concave indents are configured contacts one end-surface of the movable support. A number of protrusions are configured on the end-surface of the movable support to mate the concave indents. In the invention, a rotation axis is constituted by a few parts including a sleeve, an elastic body, an indented washer, and a movable part. Therefore, the rotation axis is characterized by simple structure, small size, low cost, and good reliability.
