Earth terminal is setup on circuit board. Being connected to the antenna electrically, the signal cable is in use for transmitting electromagnetic wave signal. Being connected to signal cable and earth terminal electrically, the conduction portion is in use for conducting electromagnetic interference signal to earth terminal. In the instance, WCD can conduct electromagnetic interference signal to earth terminal of printing circuit board effectively so as to reduce WCD generated electromagnetic interference on outside.
Description
[technical field]
The present invention relates to a kind of electronic installation, relate in particular to a kind of radio communication device.
[background technology]
Radio communication device is when transmitting signal, and the noise signal that its internal electronic element produced can be launched by antenna, produces electromagnetic interference (EMI) to external world.Therefore, all there is corresponding standard many in the world countries for the electromagnetic interference detection of radio communication device, and according to dissimilar radio communication device formulations different standards are arranged.For example, radio communication device desires to enter the European market must at first pass through (the European Economic Community of the European Economic Community, EEC) standard of Zhi Dinging, and checked by its accredited laboratory is if fail by check then can not enter the European market.
Therefore, spare no expense manpower and material resources of the manufacturer of radio communication device reduce electromagnetic interference.Method at present commonly used is that the signal cable at antenna installs magnet ring additional and isolates electromagnetic interference signal, but the electromagnetic interference that this way can suppress is limited.
[summary of the invention]
For solving the deficiency that above-mentioned prior art exists, a kind of radio communication device need be provided, this radio communication device can effectively effectively conduct to electromagnetic interference signal the earth terminal of printed circuit board (PCB), thereby reduces the electromagnetic interference that radio communication device produces to external world.
A kind of radio communication device comprises antenna, circuit board, signal cable, and conducting part.Antenna is used for receiving or electromagnetic signals.Circuit board is provided with earth terminal.Signal cable and antenna electrically connect, and are used to transmit electromagnetic wave signal.Conducting part and signal cable and earth terminal electrically connect, and are used for electromagnetic interference signal is conducted to earth terminal.
Radio communication device in the embodiment of the invention can effectively conduct to electromagnetic interference signal the earth terminal of printed circuit board (PCB), produces electromagnetic interference to external world thereby reduce radio communication device.

[specific embodiment]
See also Fig. 1, be depicted as the schematic perspective view of radio communication device 10 in one embodiment of the invention.
In the present embodiment, radio communication device 10 comprises antenna 100, positioner 120, signal cable 140, conducting part 160, printed circuit board (PCB) 180, and housing 190.
In the present embodiment, antenna 100 is used for receiving or electromagnetic signals, and is inseparable formula antenna, and signal cable 140 is used to transmit electromagnetic wave signal.Antenna 100 is fixed in housing 190 by first positioner 120, and electrically connects with signal cable 140.Printed circuit board (PCB) 180 comprises perforation 182, and perforation 182 is the earth terminal of printed circuit board (PCB) 180 simultaneously, and its surface is coated with metal level.In the present embodiment, conducting part 160 is the conduction cable, it is electrically connected at perforation 182 and signal cable 140, be used for electromagnetic interference signal is conducted to perforation 182 (earth terminal) from antenna 100, make electromagnetic interference signal can not launch, reach and reduce the effect that radio communication device 10 disturbs to external world by antenna 100.
See also Fig. 2, be depicted as the schematic perspective view of radio communication device 20 in another embodiment of the present invention.
In the present embodiment, the printed circuit board (PCB) 180 of radio communication device 20 is provided with grounding metal plane 184, and the function of other element and layout are identical with radio communication device 10.Conducting part 160 and grounding metal plane 184, and signal cable 140 electrically connects, thereby electromagnetic interference signal is conducted to grounding metal plane 184 (earth terminal) from antenna 100, make electromagnetic interference signal can not launch, reach and reduce the effect that radio communication device 20 disturbs to external world by antenna 100.
See also Fig. 3, be depicted as the schematic perspective view of radio communication device 30 in further embodiment of this invention.
In the present embodiment, antenna 200 is detachable antenna, and printed circuit board (PCB) 180 is provided with location hole 186, and housing 190 is provided with holder 150.Conducting part 130 is a sheet metal, and it comprises first stiff end 132 and second stiff end 134.First stiff end 132 and first positioner 120 and antenna 200 electrically connect, and are fixed between first positioner 120 and the housing 190.Second stiff end 134 is by location hole 186, and the holder 150 and second positioner 170 are fixed between printed circuit board (PCB) 180 and the housing 190.
In the present embodiment, because the earth terminal of 130 whiles of portion with antenna 100 and printed circuit board (PCB) 180 electrically connects, so conducting part 130 can conduct to earth terminal from antenna 200 with electromagnetic interference signal, make electromagnetic interference signal can not launch, reach and reduce the effect that radio communication device 30 disturbs to external world by antenna 200.
