Abstract
The utility model relates to a kind of flat cable, it comprises the isolated some holding wires in left and right and some earth connections, the conducting resinl also comprising two-layer conductive fabric and be bonded together by this two-layer conductive fabric, described holding wire and earth connection, between this two-layer conductive fabric, improve EMC performance.
Description
Technical field
The utility model relates to a kind of flat cable.
Background technology
EMC (Electro Magnetic Compatibility, Electro Magnetic Compatibility) be defined as " equipment and system can normally work in its electromagnetic environment and not to environment in the ability of electromagnetic disturbance that can not bear of anything formation ", this definition comprises the meaning of two aspects, first, this equipment normally should be able to work under certain electromagnetic environment, and namely this equipment should possess certain electromagnetic immunity (EMS); Secondly, the electromagnetic disturbance that this equipment self produces can not produce excessive impact to other electronic products, i.e. electromagnetic disturbance (EMI).
For solving the EMC performance of equipment, tradition settling mode is on flat cable, arrange a shielding magnet ring, shielding magnet ring is generally provided at head or the afterbody of flat cable, namely input signal or output signal are played shielding, prevent the effect of harassing other electronic products, as the flat cable on keyboard simultaneously.Conventional flat cable does not structurally consider EMC aspect, is in most cases add magnet ring as required when flat cable is assembled.
Utility model content
The purpose of this utility model there are provided a kind ofly has the flat cable improving EMC performance.
For realizing aforementioned object, the utility model adopts following technical scheme: a kind of flat cable, it comprises the isolated some holding wires in left and right and some earth connections, the conducting resinl also comprising two-layer conductive fabric and be bonded together by this two-layer conductive fabric, described holding wire and earth connection are between this two-layer conductive fabric.
The utility model can also adopt following technical scheme: a kind of flat cable, it comprises the isolated some holding wires in left and right, some earth connections, the two-layer aluminium foil layer also comprising two-layer conductive fabric, be positioned at the two-layer PET film inside conductive fabric and be fitted in respectively outside PET film, described holding wire and earth connection are combined between this two-layer PET film by melt viscosity.
As further improvement of the utility model, described conductive fabric is bonded in outside aluminium foil layer by conducting resinl.
As further improvement of the utility model, described holding wire comprises the insulator of conductor and parcel conductor, and earth connection is the wire of nude, and described earth connection and conductive fabric are electrically connected.
The utility model flat cable, owing to arranging two-layer conductive fabric, improves EMC performance.
Accompanying drawing explanation
Fig. 1 is the generalized section of the utility model first execution mode flat cable.
Fig. 2 is the generalized section of the utility model second execution mode flat cable.
Embodiment
Refer to shown in Fig. 1, the conducting resinl 14 that the utility model first execution mode flat cable 10 comprises the isolated some holding wires 11 in left and right, some earth connections 12, two-layer conductive fabric 13 and is bonded together by this two-layer conductive fabric 13.Holding wire 11 and earth connection 12 are between this two-layer conductive fabric 13.
Each holding wire 11 comprises the insulator 112 of conductor 111 and parcel conductor 111, and earth connection 12 is the wire of nude, because conducting resinl 14 has electric conductivity, make together with the common short circuit of each earth connection 12 and conductive fabric 13, when this flat cable 10 is connected with electric connector (not shown), by the connection of conductive fabric 13 with the metal shell of electric connector, realize good EMC performance.
Refer to shown in Fig. 2, the utility model second execution mode flat cable 20 improves on above-mentioned flat cable 10, improve the EMI protection of flat cable 20, its increase has the two-layer PET film 15 be positioned at inside conductive fabric 13 and the two-layer aluminium foil layer 16 be fitted in respectively outside PET film 15, holding wire 11 and earth connection 12 are bonded between this two-layer PET film 15 by PUR 17, conductive fabric 13 is bonded in outside aluminium foil layer 16 by conducting resinl 14, and this flat cable 20 can reach the purpose of this utility model equally.
Although be example object, disclose preferred implementation of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
