Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to an embedded SMA anti-static rod antenna. Background Art

[0002] The embedded SMA anti-static rod antenna is a type of antenna widely used in wireless communication devices. Its main function is to send and receive signals in a wireless communication system, and it is widely used in WiFi routers, wireless monitoring devices, Internet of Things terminal devices, and other electronic devices that require wireless communication functions.

[0003] At present, the length of the embedded SMA anti-static rod antenna on the market is usually fixed and mostly integrated design. This means that the antenna and its connection part are a whole, and the length or angle cannot be adjusted freely. Although this design has its advantages in the production and installation processes, such as reducing manufacturing costs and simplifying installation steps, it also brings some inconveniences in actual use.

[0004] Especially when the device needs to be placed against the wall, the fixed-length and integrated antenna may become an obstacle. Since the antenna cannot be adjusted, the device needs to reserve a certain space to accommodate the protruding antenna, which not only occupies extra space but also may affect the overall aesthetics and layout rationality of the device. In addition, in some environments with limited space or special installation positions, it is difficult for users to find a position that can ensure signal quality and does not affect the placement of the device.

[0005] In view of the above problems, we have developed an embedded SMA anti-static rod antenna. Summary of the Utility Model

On the top of the fixed end, there is a step, and a connecting hole is opened on the top of the step.

[0009] The sliding nut can connect the fixed end to the SMA interface on the main board and dock the guide core with the connection interface on the main board.

[0010] In a preferred embodiment, it further includes an extension sleeve. A first connecting screw is provided at the bottom of the extension sleeve, and the first connecting screw is threadedly connected to the connecting hole. A threaded hole is provided at the top of the extension sleeve.

[0011] Screw the first connecting screw at the bottom of the extension sleeve into the connecting hole, and thus a connection can be formed.

[0012] In a preferred embodiment, it further includes a receiving rod. A second connecting screw for cooperating with the threaded hole is provided at the bottom of the receiving rod, and a receiving terminal is provided at the top of the receiving rod.

[0013] Screw the second connecting screw at the bottom of the receiving rod into the threaded hole, and thus the fixed end, the extension sleeve and the receiving rod can be installed, and external signals can be received through the receiving terminal.

[0014] In a preferred embodiment, first anti-slip grooves are equidistantly provided on the outer side of the extension sleeve.

[0015] By providing the first anti-slip grooves, it can make it more convenient for the user to turn the extension sleeve.

[0016] In a preferred embodiment, second anti-slip grooves are equidistantly provided on the outer side of the receiving rod.
