Abstract
The invention relates to a flat cable which comprises a plurality of pairs of differential signal lines separated in a left-right mode, at least one grounding bare wire, an aluminum foil film layer and a Mylar layer wrapping the aluminum foil film layer. Each differential signal line is wrapped with an insulating material. The flat cable further comprises an adaptable-shape adhesive layer, wherein the adhesive layer is formed by a conductive adhesive and enables the differential signal lines and the grounding bare wire to be respectively bonded with the aluminum foil film layer. Due to the fact that the adhesive has viscidity and conductivity, the aluminum foil film layer is combined with the differential signal lines and the grounding bare wire, movements of the differential signal lines and the grounding bare wire relative to the aluminum foil film layer are limited, the stability of a flat cable structure is improved, the grounding bare wire and the aluminum foil film layer form reliable electrical connection, and the impedance control and the high-frequency performance of the flat cable are improved. The flat cable is simple in manufacture process and low in production cost.
Description
Technical field
The present invention relates to a kind of flat cable, relate in particular to a kind of flat cable for transmitting high-frequency signal.
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 and instrument and meter.Yet in signals transmission, especially in high-frequency signal transmitting procedure, flat cable is very easily subject to the interference of external electromagnetic signal, thereby often need improve the structure of flat cable inside, it is a kind of in order to pass the flat cable of USB 3.0 signals that related art can disclose for No. CN202694868U with reference to the Chinese utility model patent that on January 23rd, 2013 is announced, this flat cable comprises some to differential signal conductors, the insulator that coated each signal conducts electricity and the two-layer aluminium foil wheat that is wrapped in insulator exterior are drawn layer, this two-layer aluminium foil wheat is furnished with earthing conductor between drawing, be that earthing conductor is clamped in two-layer aluminium foil wheat and draws between layer, due to being set, two-layer aluminium foil wheat draws layer, increase the shield effectiveness of electromagnetic signal to external world, but, this flat cable cost is higher, pliability is lower, in addition, it between each earthing conductor, is short circuit connection, cannot disconnect, reduce the scope of application.
So, be necessary to design a kind of new flat cable to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide a kind of flat cable that improves structural stability, impedance Control and high frequency performance that has.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of flat cable, it comprises that left and right is isolated and some differential signal line, at least one grounding terminal, aluminium foil rete and the wheat that is wrapped in aluminium foil rete outside is drawn to layer, each differential signal line outer wrap has insulating material, described flat cable also comprises conformal adhesive phase, described adhesive phase is that conductivity type adhesive forms, and described adhesive phase is bonded together differential signal line and grounding terminal respectively with aluminium foil rete.
Flat cable of the present invention also comprises conformal adhesive phase, described adhesive phase is that conductivity type adhesive forms, described adhesive phase is bonded together differential signal line and grounding terminal respectively with aluminium foil rete, because adhesive phase has viscosity and electric conductivity, aluminium foil rete and differential signal line and grounding terminal are combined, restriction differential signal line and grounding terminal move relative to aluminium foil rete, promoted the stability of flat cable structure, and impel formation between grounding terminal and aluminium foil rete to be electrically connected reliably, impedance Control and the high frequency performance of flat cable have been improved, flat cable manufacturing process is simple, production cost is low.
Accompanying drawing explanation
Fig. 1 is the cutaway view of flat cable of the present invention.
Fig. 2 is the cutaway view of the flat cable of another execution mode of the present invention.
Embodiment
Refer to shown in Fig. 1, flat cable 100 of the present invention comprises that left and right is isolated some to two aluminium foil retes 40 of differential signal line 10, some grounding terminals 20, conformal adhesive phase 30, almost parallel and be wrapped in aluminium foil rete 40 two wheats outside and almost parallel and draw layer 50.
Each differential signal line 10 outer wrap has insulating material, and differential signal line 10 is disposed generally in a plane with grounding terminal 20.Aluminium foil rete 40 draws layer 50 to arrange around differential signal line 10 and grounding terminal 20 with wheat.Adhesive phase 30 is the formation of conductivity type adhesive, conductivity type adhesive is called for short conducting resinl, it is a kind of adhesive with viscosity and electric conductivity, adhesive phase 30 is between aluminium foil rete 40, in differential signal line 10 and some grounding terminal 20 both sides, two aluminium foil retes 40 are bonded to each other, each aluminium foil rete 40 and differential signal line 10 and grounding terminal 20 are bonded together respectively simultaneously.
Because adhesive phase 30 has viscosity and electric conductivity, aluminium foil rete 40 and differential signal line 10 and grounding terminal 20 are combined, restriction differential signal line 10 and grounding terminal 20 move relative to aluminium foil rete 40, promoted the stability of flat cable 100 structures, and impel formation between grounding terminal 20 and aluminium foil rete 40 to be electrically connected reliably, the impedance Control and the high frequency performance that have improved flat cable 100, flat cable 100 manufacturing process are simple, and production cost is low.
Refer to shown in Fig. 2, the flat cable 200 of another execution mode of the present invention, some differential signal line 10A is arranged on a horizontal plane, and grounding terminal 20A is between each is to differential signal line 10A, grounding terminal 20A and each to differential signal line 10A flat cable 200 radially triangularity arrange, grounding terminal 20A, between differential signal line 10A and aluminium foil rete 40 threes, by adhesive phase 30, be bonded together, can limit differential signal line 10A equally and grounding terminal 20A moves relative to aluminium foil rete 40, promote the stability of flat cable 100 structures, and impel formation between grounding terminal 20A and aluminium foil rete 40 to be electrically connected reliably, impedance Control and the high frequency performance of flat cable 200 have been improved, the manufacturing process of flat cable 200 is simple, production cost is low, so this flat cable 200 can be reached the object of the invention equally.
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.
