Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a surface mount connector and connector assembly for fixing a protective cover. Background Technology

[0002] Connectors are commonly used components in electrical engineering. Their function is to connect circuits on different devices or different modules within a circuit, allowing current or signals to flow or be transmitted, enabling the circuit to perform its intended function. Existing connectors include plugs and sockets. The connection method typically involves inserting the plug into the socket, with the conductive terminals of the plug and socket electrically connected.

[0003] There is a surface mount connector that is fixed to the surface of a device for electrical connection of different functional modules. Since the device surface is exposed, a corresponding protective structure is required. Existing surface mount connectors are generally equipped with protective covers. When the connector is not in use, the protective cover is closed for protection. When the connector is connected, the protective cover is separated from the connector. In order to avoid loss, existing protective covers are usually connected to the connector body by a cable. However, when the connector is used on some mobile devices, the protective cover cannot be fixed, which often leads to the protective cover being damaged by the device or being knocked off, which poses certain safety hazards.

[0012] A further proposed solution is that the surface mounting plate and the extension arm are respectively connected to two adjacent outer side walls, and the connecting plate is provided with a lever, with the lever and the extension arm located on opposite sides.

[0013] A further proposed solution is that the first hinge and the second hinge are respectively arranged with hinge holes, the pivot passes through the first hinge and the second hinge, the torsion spring is sleeved on the pivot, and the two ends of the torsion spring abut against the protective cover and the extension arm respectively.

[0014] A further alternative is to have a through-hole provided radially in the second hinge section, through which the end of the rotating shaft is inserted into the second hinge section.

[0015] To achieve the second objective of this utility model, this utility model provides a connector assembly, including a connector and a surface mount connector as described above, wherein the connector is connected to a housing, a locking element engages with the connector, and a protective cover is located on the side of the connector.

[0016] The beneficial effects of this utility model are as follows: The outwardly extending extension portion can be fixedly connected to the surface of the device via a fixed connection portion, facilitating the connection and use of surface-mount connectors. Furthermore, the protective cover is hinged to the extension arm of the outer wall of the housing, and the hinge position of the protective cover is located outside the insertion port. Therefore, when the housing is connected to other connectors, the protective cover is located on the side of the connector, so as not to affect normal insertion and connection. The protective cover has a relatively fixed position, thus preventing damage or impact to the protective cover. Also, the protective cover and the surface-mount plate are located on adjacent outer walls, so the opening position and closing trajectory of the protective cover are not interfered with by the surface of the device. Moreover, the arrangement of the rotation gap allows the hinge arm of the locking member to rotate smoothly between the surface of the device and the outer wall, thus not affecting the connection or separation of the protective cover and the connector. Furthermore, the arrangement of the torsion spring further stabilizes the position of the protective cover, and the arrangement of the through-hole facilitates the connection between the protective cover and the rotating shaft.
