The ground structure of this technological optimization FFC shielded wire has reduced the ground connection degree of difficulty, and save material has strengthened the shielding effect greatly. The utility model discloses simple structure, the shielding effect is strong, and the shielding effect is stable.
Description
Technical field
The utility model relates to winding displacement field, is specifically related to a kind of high stability FFC shielding conductor.
Background technology
FFC winding displacement is widely used in the connection in various printer between printhead and mainboard, as the connection between the Signal transmissions of the products such as plotter, scanner, photocopier, sound equipment, liquid crystal electrical equipment, facsimile machine, video disc player and wiring board.In modern electrical equipment, FFC winding displacement is almost ubiquitous.
Because FFC winding displacement can select arbitrarily wire count and spacing, therefore, make on line more convenient, thus greatly reduce the volume of electronic product, reduce production cost, enhance productivity.In view of the feature that FFC winding displacement is above-mentioned, it is suitable between moving-member and mainboard, pcb board is to being used as data transmission cable between pcb board, in miniaturized electric equipment.Along with the shielding conductor of FFC winding displacement as Signal transmissions uses, the problem of FFC shielding conductor how ground connection draws attention gradually.Existing FFC shielding conductor is generally respectively inserted an earth connection and is closely affixed with selected wire around several selected wires, then the insulating barrier above earth connection outputs the slotted eye matched with earth connection diameter, ticks partial earthing line as grounding ports in slotted eye place.So not only grounding ports insecure, unstable, add difficulty of processing, and consume wire many, waste material, shield effectiveness is poor.
Utility model content
In view of this, the utility model, for the deficiencies in the prior art, discloses a kind of high stability FFC shielding conductor.
The purpose of this utility model is achieved through the following technical solutions:
A kind of high stability FFC shielding conductor, comprise FFC shielding conductor, conductive coating, conducting film and dielectric film, described FFC shielding conductor comprises the wire group be made up of some wires and the insulating barrier covering wire group, at least one earth lead and some ungrounded wires is comprised in described wire group, the insulating barrier that described earth lead is corresponding offers the width bar hole identical with earth lead diameter, the each end of described earth lead is at least provided with a bar hole, described conductive coating penetrates bar hole and is connected with earth lead, described conducting film wrap insulate layer and conductive coating, described dielectric film covers conducting film.
Conductive coating is connected with earth lead, is grounding ports with conductive coating, simplifies FFC shielding conductor ground structure, greatly reduces ground connection difficulty, stable connection.Bar hole width is identical with diameter of wire, both can make being connected with earth lead of conductive coating maximum area, can not have influence on again ungrounded wire around.Conducting film is connected with conductive coating, utilizes conducting film ground connection namely can shift electromagnetic interference and the radio frequency interference of FFC shielding conductor inside, can shift again electromagnetic interference and the radio frequency interference of FFC shielding conductor outside, enhance shield effectiveness greatly.
Further, a ungrounded wire is had at least between every described earth lead.
Be separated with ungrounded wire between earth lead, earth lead can be made more to disperse, reach better shield effectiveness.
Further, described conductive coating is higher than insulating barrier.
Conductive coating is higher than insulating barrier, so using conductive coating as the easier ground connection of grounding ports, easy to connect.
Further, described conducting film and dielectric film two ends are lower than insulating barrier.
Conducting film length, lower than insulating barrier, neither affects the stability of shield effectiveness, and the port not affecting again FFC shielding conductor two ends connects.
The utility model, relative to prior art, has following beneficial effect:
This technical optimization ground structure of FFC shielding conductor, reduces ground connection difficulty, saves material, greatly strengthen shield effectiveness.
The utility model structure is simple, and shield effectiveness is strong, and shield effectiveness is stablized.
