Description
Technical Field
The utility model belongs to the technical field of the circuit board, concretely relates to FPC winding displacement structure.
Background
Consumer electronics product function is more and more, and whole functions can not be realized to inside mainboard of product, and this just needs the polylith mainboard to realize jointly, needs FPC (Flexible Printed Circuit, Flexible Circuit board) winding displacement to be connected between mainboard and the mainboard. When the main board is connected, the fpc (flexible Printed circuit) cable may cause noise leakage and electromagnetic interference due to the problem of the self-reference layer.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the FPC flat cable structure can solve the problem of electromagnetic interference generated by the FPC flat cable, and does not change the impedance of the FPC flat cable.
In order to solve the technical problem, the technical scheme of the utility model is that:
the utility model provides a FPC winding displacement structure, includes the FPC winding displacement, the both ends of FPC winding displacement are provided with the winding displacement pin that is used for connecting the mainboard, the tow sides of FPC winding displacement all are provided with and inhale the ripples coating.
Further, the wave-absorbing coating is a ferrite coating.
Further, the wave-absorbing coating is coated on the FPC wire arrangement.
Furthermore, the wave-absorbing coating is coated on the adhesive layer, and the adhesive layer is adhered to the surface of the FPC.
After the technical scheme is adopted, the beneficial effects of the utility model are that:
because the utility model discloses a FPC winding displacement structure includes the FPC winding displacement, and the both ends of FPC winding displacement are provided with the winding displacement pin that is used for connecting the mainboard, and the tow sides of FPC winding displacement all are provided with the microwave absorbing coating, and the electromagnetic wave that the FPC winding displacement produced can effectively be absorbed to the microwave absorbing coating to solve the electromagnetic interference problem that the FPC winding displacement produced, and do not change the impedance of FPC winding displacement.
