Abstract
Disclosed is an electromagnetic-interference-resistant terminal including a mobile-terminal body, an FPC arranged on the mobile-terminal body and a shoulder microphone used for being connected with an external device. The mobile-terminal body is connected with the shoulder microphone through the FPC. The interface FPC includes a signal-wire layer and host formations distributed at the two sides of the signal-wire layer. Signal wires of the shoulder microphone are connected with the signal-wire layer. The host formations at the two sides guide electromagnetic waves of the signal-wire layer into formations of the mobile-terminal body. A layer of magnetic ring is sleeved at an interface of the shoulder microphone. The magnetic ring is used for eliminating part of the electromagnetic waves coupled with the shoulder microphone. Through adding the magnetic ring at an end of a cabled peripheral (such as the shoulder microphone), close to the interface, and carrying out shielding processing on the interface FPC, demagnetization through the magnetic ring and shielding can be carried out so that electromagnetic-compatibility problems caused by a transmitting antenna on the cabled peripheral can be reduced greatly.
Description
Technical field
the present invention relates to the terminal with wired peripheral hardware of a kind of terminal equipment, particularly a kind of anti-electromagnetic interference.
Background technology
When wireless terminal antenna is launched, external peripheral hardware coupling firing antenna electric magnetic wave, the external interface by terminal imports in pcb board, thereby has occurred the electromagnetic interference problem of terminal inner, has caused the problems such as terminal is corresponding slowly, deadlock.
for avoiding this problem, prior art is forced to choice for use wireless peripheral, or reduces the transmitting power of wireless terminal, in order to reduce the impact of aerial radiation on terminal.
Summary of the invention
The terminal that the invention provides a kind of anti-electromagnetic interference, is characterized in that, comprises terminal body, is located at FPC on described terminal body and for connecting the shoulder miaow of external equipment, described terminal body is connected with described shoulder miaow by described FPC;
Described FPC comprises that a signal line layer and branch are on the main stratum of described signal line layer both sides, and described shoulder miaow is connected with described signal line layer, and the main stratum of described both sides imports the electromagnetic wave of signal line layer on the main ground of terminal body;
The interface cover of described shoulder miaow has one deck magnet ring, the electromagnetic wave that described magnet ring is coupled for eliminating part and described shoulder miaow.
The present invention is by installing magnet ring to wired peripheral hardware (as shoulder miaow) additional near interface end, and docking port FPC carries out shielding processing simultaneously, and then can greatly reduce transmitting antenna antenna to the caused electromagnetic compatibility problem of wired peripheral hardware by magnet ring demagnetization with shielding to shield.
Certainly, implement arbitrary product of the present invention and might not need to reach above-described all advantages simultaneously.
Accompanying drawing explanation
The mobile terminal structure schematic diagram that Fig. 1 provides for the embodiment of the present invention;
The FPC external structure schematic diagram that Fig. 2 provides for the embodiment of the present invention;
The FPC composition structural representation that Fig. 3 provides for the embodiment of the present invention.
execution mode
The embodiment of the present invention provides a kind of terminal of anti-electromagnetic interference, and it comprises terminal body 2, be located at FPC1 on described terminal body 2 and for connecting the shoulder miaow 3 of external equipment, terminal body 2 is connected with shoulder miaow 3 by FPC1;
Described interface FPC1 comprises that a signal line layer 12 and branch are on the main stratum of signal line layer 12 both sides, and the holding wire of shoulder miaow 3 is connected with signal line layer 12, and the main stratum of described both sides imports the electromagnetic wave of signals layer on the main ground of terminal body 2;
The interface cover of shoulder miaow 3 has one deck magnet ring 4, the electromagnetic wave that magnet ring 4 is coupled for eliminating part and shoulder miaow 3.
Shown in described Fig. 2, the FPC surface that the present embodiment provides is provided with a plurality of holding wires hole for connecting holding wire and the signal line layer of takeing on miaow 3.
The terminal of the anti-electromagnetic interference that the present embodiment provides can be intercom, can certainly be the other-end with intercommunication function, and the present invention does not limit the particular type of terminal.
The present invention is by installing magnet ring to wired peripheral hardware (as shoulder miaow) additional near interface end, and docking port FPC carries out shielding processing simultaneously, and then can greatly reduce transmitting antenna antenna to the caused electromagnetic compatibility problem of wired peripheral hardware by magnet ring demagnetization with shielding to shield.
The disclosed preferred embodiment of the present invention is just for helping to set forth the present invention above.Preferred embodiment does not have all details of detailed descriptionthe, and also not limiting this invention is only described embodiment.Obviously, according to the content of this specification, can make many modifications and variations.These embodiment are chosen and specifically described to this specification, is in order to explain better principle of the present invention and practical application, thereby under making, technical field technical staff can understand and utilize the present invention well.The present invention is only subject to the restriction of claims and four corner and equivalent.
