Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of the utility model protection.
First embodiment
Fig. 1 is refer to, is the sectional view for the FPC lines that the utility model first embodiment provides.The utility model embodiment
A kind of FPC lines, including signals layer 101 and stratum 102 are provided, the signals layer 101 can be bonded with the stratum 102.It is flexible
Circuit board (Flexible Printed Circuit, FPC) can have using polyimides or polyester film to be a kind of made of base material
There are height reliability, flexible printed circuit.With the characteristics of Distribution density is high, in light weight, thickness of thin, good bending property.
The signals layer 101 is used to be communicated, such as on unmanned plane, the video camera and master control core that are connected with FPC lines
Piece, signals layer 101 is used to transmit the picture signal of video camera to main control chip, and the control instruction of main control chip is transmitted
To video camera, for being in communication with each other between video camera and main control chip.
The stratum 102 is used to be grounded, and can keep low potential, the electro-magnetic wave absorption that signals layer 101 is sent.
The stratum 102 of the present embodiment is arranged at the side of the signals layer 101, when passing through electric current due to signals layer 101, production
Raw electromagnetism wave direction surrounding transmitting, therefore the top of signals layer 101 also can outwards launch electromagnetic wave, and other circuit modules are produced
Signal interference.The opposite side of signals layer 101 of the present embodiment is provided with earthing strip 103, and earthing strip 103 is turned on stratum 102, also may be used
The electro-magnetic wave absorption that signals layer 101 is sent, the external influence of the electromagnetic wave of FPC lines can be reduced.It is corresponding, it is also possible to prevent
Outside electromagnetic wave is disturbed the signal in signals layer 101.
Because earthing strip 103 and stratum 102 are used to electromagnetic wave absorption, therefore conductive material is used, signals layer 101 is used for
Transmission signal is also conductive material, therefore insulating barrier 104 is also provided with outside the signals layer 101, and insulating barrier 104 is by the signal
Layer 101 wraps up, and the insulating barrier 104 is used to separate the signals layer 101 and the stratum 102, the earthing strip 103, prevents
Only directly by the current earthing in signals layer 101.In the present embodiment, insulating barrier 104 is by the levels of signals layer 101 and side wall
All coverings, can also prevent from leaking electricity, the material of the insulating barrier 104 can use epoxy resin.The earthing strip and described
Layer can use copper material.
In the present embodiment, the earthing strip 103 includes both ends, and both ends are connected with the stratum 102, the earthing strip
103 be connected with the stratum 102 after structure the signals layer 101 and insulating barrier 104 are surround.
Fig. 2 is refer to, is the partial structural diagram for the FPC lines that the utility model first embodiment provides.In order to ensure
For earthing strip 103 to the absorption of electromagnetic wave, the number of earthing strip 103 is multiple.In the present embodiment, multiple earthing strips 103 are equal
Even is distributed on signals layer 101, i.e., the spacing d phases in multiple earthing strips 103 between two earthing strips 103 of arbitrary neighborhood
Together.
Spacing between two neighboring earthing strip 103 is satisfied by formula d≤λ/20, and wherein d is the two neighboring ground connection
Spacing between bar 103, the λ are by the minimum wavelength of signal in the signals layer 101.Due to two neighboring earthing strip
Spacing d between 103 is smaller, the earthing strip more than 103 of the top of signals layer 101 covering, better to the assimilation effect of electromagnetic wave, examines
The spacing d considered between two neighboring earthing strip 103 is too small, the hardness of whole FPC lines can be caused to uprise, so two neighboring connect
Spacing d between ground bar 103 can be set according to actual use situation.
Fig. 3 is refer to, is the signal frequency of signals layer 101 and week in the FPC lines of the utility model first embodiment offer
The electric-field intensity graph of a relation enclosed.
In the present embodiment, the length of the FPC lines used is 15cm, highest signal that the signals layer 101 in FPC lines passes through
Frequency is 400MHz, electric-field intensity is detected in the axis direction perpendicular to FPC lines, testing result is as shown in Figure 3.
In figure, I line is that FPC line lengths are 15cm, and the side of signals layer 101 is provided with stratum 102, and opposite side is provided with more
Individual width is 1 millimeter of earthing strip 103, two adjacently the distance between bar 103 be 3.75 centimetres, in distance FPC lines
At 3 meters of axis direction, electric-field intensity is with the curve of the change of the signal frequency of signals layer 101.II line is that FPC line lengths are
15cm, the side of signals layer 101 are provided with stratum 102, and at 3 meters of the axis direction of distance FPC lines, electric-field intensity is with letter
The curve of the change of the signal frequency of number floor 101.As seen from the figure, the FPC lines of earthing strip 103 are provided with relative to being not provided with connecing
The FPC lines of ground bar 103, the electric-field intensity of surrounding is smaller, and caused electromagnetic wave is smaller, can effectively reduce FPC lines to other electricity
The signal interference of road module.
Second embodiment
Fig. 4 is refer to, is sectional view of the FPC lines in the position of earthing strip 103 of the utility model second embodiment offer.This
In embodiment, the FPC lines include signals layer 101, insulating barrier 104, stratum 102 and earthing strip 103.
The insulating barrier 104 wraps up the signals layer 101, and stratum 102 is arranged at the side of the insulating barrier 104, institute
