Abstract
The utility model relates to a flat cable. The flat cable comprises multiple pairs of differential signal wires, at least one naked grounding wire, aluminum foil films and Mylar layers, wherein each differential signal wire is wrapped in an insulating material; and the flat cable also comprises an adhesive layer in an appropriate shape, the adhesive layer is formed by conductive adhesive, and the differential signal wires and the naked grounding wire are bonded with the aluminum foil films via the adhesive layer. Due to adhesiveness and conductive performance of the adhesive layer, the aluminum foil films can be combined with the differential signal wires and the naked grounding wire, so that movement of the differential signal wires and the naked grounding wire relative to the aluminum foil films is limited, the structural stability of the flat cable is improved, reliable electrical connection between the naked grounding wire and the aluminum foil films is formed, and the impedance control and high frequency performance of the flat cable are improved; and the flat cable is simple in manufacturing process and low in production cost.
Description
Technical field
The utility model relates to a kind of flat cable, relates 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.
Utility model content
The purpose of this utility model has been to provide a kind of flat cable that improves structural stability, impedance Control and high frequency performance that has.
For realizing aforementioned object, the utility model 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.
As further improvement of the utility model, described differential signal line and grounding terminal are disposed generally in a plane.
As further improvement of the utility model, described grounding terminal and each to differential signal line flat cable radially triangularity arrange.
As further improvement of the utility model, described aluminium foil rete is almost parallel two, described adhesive phase is bonded to each other by this two aluminium foils rete in the both sides of differential signal line and grounding terminal.
As further improvement of the utility model, described wheat is drawn layer for two of almost parallel and covers respectively aluminium foil rete outer surface.
The utility model flat cable 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 the utility model flat cable.
Fig. 2 is the cutaway view of the flat cable of another execution mode of the utility model.
Embodiment
Refer to shown in Fig. 1, the utility model flat cable 100 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, with the both sides of some grounding terminals 20, two aluminium foil retes 40 are bonded to each other at differential signal line 10, 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 utility model, 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 utility model object equally.
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.
