Description

Flat cable

Technical field

The utility model relates to a kind of flat cable, relates in particular to a kind of ultra-thin flat cable.

Background technology

Along with the development of electronics technology product is universal, flat cable, as a kind of instrument of signal transmission, is widely used in the connection of the electronic equipments such as consumer electronics, household electrical appliances, instrument and meter.Because flat cable is frivolous, greatly reduce the volume of electronic product, be suitable between moving-member and mainboard, pcb board is between pcb board, in miniaturization electric equipment.

Utility model content

The purpose of this utility model has been to provide a kind of flat cable that can conveniently apply to realize on various connectors automated process.

For realizing aforementioned object, the utility model adopts following technical scheme: a kind of flat cable, it comprise along the insulator of the spaced some signal conductors of left and right directions, parcel signal conductor, be positioned at insulator outside earthing conductor, screen, be wrapped in the outer quilt of screen outside, described insulator is integral type structure, described earthing conductor between screen and insulator, being centered close on same straight line of described signal conductor and earthing conductor.

As further improvement of the utility model, described screen is aluminium foil or Copper Foil.

As further improvement of the utility model, described insulator is ellipsoidal structure.

As further improvement of the utility model, described screen is conductive plastic layer.

As further improvement of the utility model, the plastic material in described conductive plastic layer is PVC, PE, TPU, TPE, PP, PC or ABS etc.

As further improvement of the utility model, the shielding material in described conductive plastic layer adopts the combination of resin and conductive black.

As further improvement of the utility model, described flat cable can be used in the signals such as transferring voice, USB, HDMI.

As further improvement of the utility model, the spacing between each adjacent signal conductor is identical.

As further improvement of the utility model, the spacing of described signal conductor and earthing conductor is not less than 0.35 millimeter.

The insulator of the utility model x flat cable is integral type structure, described earthing conductor is between screen and insulator, being centered close on same straight line of described signal conductor and earthing conductor, so design, flat cable has ultra-thin band type structure, easy for installation, and can conveniently apply to realize automated process on various connectors.

Accompanying drawing explanation

Fig. 1 is the cross section view of the utility model the first execution mode flat cable.

Fig. 2 is the cross section view of the utility model the second execution mode flat cable.

Embodiment

Refer to shown in Fig. 1; the utility model the first execution mode flat cable 100 can be used in the signals such as transferring voice, USB, HDMI; it comprise along the spaced some signal conductors 10 of left and right directions, parcel signal conductor 10 insulator 20, the earthing conductor 30 that is positioned at insulator 20 outsides, screen 40, be wrapped in the outer by 50 of screen 40 outsides, outer by 50 in order to guard shield layer 40.

Insulator 20 is integral type structure and is ellipsoidal structure, earthing conductor 30 is between screen 40 and insulator 20, signal conductor 10 is centered close on same straight line with earthing conductor 30, spacing between each adjacent signal conductor 10 is identical, spacing between signal conductor 10 and earthing conductor 30 is not less than 0.35 millimeter, and screen 40 is aluminium foil or Copper Foil.

The utility model flat cable 100 so designs, and flat cable 100 has ultra-thin band type structure, easy for installation, and can conveniently apply to realize automated process on various connectors.

Refer to shown in Fig. 2, the utility model the second execution mode flat cable 200, be with the first execution mode flat cable 100 differences, this flat cable 200 adopts conductive plastic layer 60 to replace aluminium foil or Copper Foil, there is equally the effect of signal shielding, plastic material in conductive plastic layer 60 is PVC, PE, TPU, TPE, PP, PC or ABS etc., shielding material adopts the combination of resin and conductive black, so the utility model flat cable 200 has ultra-thin band type structure equally, easy for installation, and can conveniently apply to realize automated process on various connectors, thereby reach the purpose of this utility model.

Although be example object, preferred implementation of the present utility model 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 utility model of appending claims, various improvement, increase and replacement are possible.
