Description
Technical Field
The utility model belongs to electronic equipment antenna field especially relates to an extension antenna function's usb tail is inserted.
Background
An antenna is now a converter that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. Antennas of mobile phones or portable equipment with cameras and the like are generally placed on a support or a rear shell, and an FPC or LDS mode is adopted, so that the portable equipment is limited in space, insufficient in clearance of the antennas and low in efficiency.
In summary, there is a need for a method that can solve the above technical problem, and by disposing the elastic sheet on the usb interface and then connecting the antenna signal processing unit inside the terminal, the usb tail plug functions as an antenna.
SUMMERY OF THE UTILITY MODEL
In view of the foregoing prior art's weak point, an object of the utility model is to provide an expand antenna function's usb tail is inserted, and it is limited to aim at solving prior art portable equipment space, and the antenna headroom is not enough, the lower problem of efficiency.
In order to achieve the purpose, the utility model adopts the following technical proposal:
a usb tail insert for extending antenna functionality, comprising: a usb interface arranged on the external terminal; an elastic sheet is fixedly arranged at the outer metal ring of the usb interface and is connected with an antenna signal processing unit of the external terminal; wherein, the shrapnel is metal.
Preferably, the top of the metal outer ring is hollowed, the elastic sheet is pressed and tightly attached to the hollowed top, esb interface metal outer ring materials are saved, and the metal outer ring serves as an antenna.
Preferably, the usb interface is fixed on the circuit board in an inserting manner through the contact pin, and one end of the elastic sheet is fixed on the circuit board in an inserting manner and then connected with the antenna signal processing unit of the external terminal.
Preferably, the usb interface includes a socket, and the socket is disposed right below the spring plate, that is, the top of the metal coil is replaced by the spring plate.
Preferably, the thickness of the elastic sheet is 3mm, and is not limited to 3mm, and the thickness can be properly adjusted according to the process.
Preferably, the usb interface is any one of a type-a interface, a type-C interface, or a micro interface.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a usb tail plug for expanding antenna function, which comprises a usb interface arranged on an external terminal; an elastic sheet is fixedly arranged at the outer metal ring of the usb interface and is connected with an antenna signal processing unit of the external terminal; wherein, the shrapnel is metal. Through above design through setting up the shell fragment on the usb interface, the inside antenna signal processing unit of reconnection terminal realizes that the usb tail-plug serves as the function of antenna to improve antenna efficiency, solved the not enough problem of antenna headroom.
