Abstract
The invention relates to a cable. The cable comprises a conductor and a dielectric film, wherein the conductor is covered with the dielectric film and the dielectric film is made of polyethylene. The dielectric film is low in dielectric constant and is also low in impedance especially when the cable transmits high-frequency signals, and therefore loss of the signals is reduced.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to a kind of cable with dielectric film.
Background technology
Consumer electronics product is all to light, thin future development at present, as notebook computer, digital camera, mobile phone etc., and flexible flat cable (FFC) because of have softness, arbitrarily bending fold, thin thickness, volume little, connect the advantage such as simple and be widely used in consumer electronics product.The dielectric film that existing flat cable adopts is that polyethylene terephthalate (PET) material and PUR are made, and dielectric constant is higher, and especially, in the time of cable transmission high-frequency signal, impedance is higher, causes the loss of signal larger.
So, be necessary to design a kind of new cable to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide one to there is more low-impedance cable.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of cable, and the dielectric film that it comprises conductor and covers conductor, the material of described dielectric film adopts polyethylene.
The material of cable insulating film of the present invention adopts polyethylene, and the dielectric constant of dielectric film is lower, and especially, in the time of cable transmitting high-frequency signal, impedance is lower, has reduced the loss of signal.
Accompanying drawing explanation
Fig. 1 is the generalized section of first embodiment of the invention cable.
Fig. 2 is the generalized section of second embodiment of the invention cable.
Fig. 3 is the generalized section of third embodiment of the invention cable.
Embodiment
Please read shown in Fig. 1, the cable 100 of first embodiment of the invention is flexible flat cable (FFC), it comprises the some conductors 10 as holding wire and earth connection use, described some conductors 10 configure in mode arranged side by side, and the two sides of conductor 10 is coated with dielectric film 20, and dielectric film 20 materials adopt polyethylene (PE), the dielectric constant of dielectric film 20 is lower, especially in the time of cable 100 transmitting high-frequency signal, impedance is lower, has reduced the loss of signal.
Consult shown in Fig. 2, the cable 200 of second embodiment of the invention, it comprises the some conductors 10 as holding wire and earth connection use, described some conductors 10 configure in mode arranged side by side, the two sides of conductor 10 is provided with dielectric film 20A to cover conductor 10, outer surface at dielectric film 20A is disposed with from inside to outside: two-sided tape 30, screen 40 and insulated hull 50, meanwhile, two-sided tape 30, screen 40 and insulated hull 50 from bottom to top fit together.
Consult shown in Fig. 3, the cable 300 of third embodiment of the invention is with the difference of above-mentioned the second execution mode, adhesive tape 30, screen 40 and the insulated hull 50 of this cable 300 are all set to spaced apart from each other two-layer, conductor 10 and dielectric film 20C are co-located between this two-layer adhesive tape 30, screen 40 and insulated hull 50, the material of velum 20C also adopts polyethylene, and therefore this cable 300 can be reached object of the present invention too.
In other embodiments, adhesive tape 30 is substituted by adhesive, and adhesive adopts self-adhesive or PUR etc.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
