Abstract

Disclosed in the utility model is a laminated conductor-based flat data line. The flat data line comprises flat conductors and an insulated film. The plurality of flat conductors are separated from each other at intervals and are arranged to form flat conductor layers; and the flat conductor layers are coated in the insulated film. The insulated film at least coats two layers of flat conductor layers. According to other embodiments, two or three flat conductor layers are coated in the insulated film. And a shielding layer is pasted at the outer side of the insulated film; and flat conductors in all the flat conductor layers are staggered with each other. The provided flat data line has the characteristics of convenient manufacturing and using; phenomena of short circuit and plugging misplacement can be effectively avoided.

Description

The flat data wire of laminated conductor

Technical field

The utility model relates to a kind of flexible data line for the signal transmission, relates in particular to the improvement of flat data wire structure.

Background technology

The flexible flat data wire is a kind of signal transmission assembly, has the advantages such as deflection arbitrarily, high-speed transfer signal, can select arbitrarily wire number and spacing, and on line is convenient, greatly reduces the volume of electronic product, reduces production costs, and enhances productivity.Be widely used between moving-member and mainboard, pcb board is between pcb board, in the miniaturization electric equipment, is used as data transmission cable, and is almost ubiquitous in modern electrical equipment.

Existing flat data wire mainly comprises the parts such as strap, insulating barrier, and its strap adopts flat copper conductor, and insulating barrier adopts the PET insulating material, and some flat copper conductors are arranged parallel to each other, and are coated in insulating barrier.But existing this structure is the conductor structure of individual layer, in order to limit its data wire beam overall, to save the occupied space of flat data wire, between its conductor, spacing distance is often 0.3mm ~ 1.0mm, the flat data soft arranging wire of this closely spaced single-conductor, not only increased the difficulty of manufacturing of cable self, and caused the plug connector manufacture difficulty of pegging graft with it, actual the use, with when assembling of pegging graft, short circuit easily occurs or contact the anomaly such as dislocation, cause the signal transmission fault.

The utility model content

For the existing above-mentioned technical problem of prior art, technical problem to be solved in the utility model is to provide the flat data wire of laminated conductor that a kind of conductor spacing is large, be convenient to manufacture.

In order to solve the problems of the technologies described above, the flat data wire of laminated conductor of the present utility model, comprise strap and dielectric film, and some straps are arranged in the strap layer spaced reciprocally, this strap layer is coated in dielectric film, in described dielectric film, is coated with at least two layers of strap layer.

in above-mentioned structure, due to the strap layer that is coated with multilayer in insulating barrier, the signal of the strap transmission in this data wire with laminated conductor structure, thereby make in limited Section Space more strap can be set, and can not cause the beam overall of flat data wire to strengthen, with existing flat data wire, compare, under identical live width condition, spacing between wire can arrange larger, not only be convenient to manufacture and the production of data wire, and be convenient to it the making production of the plug-in unit of mutually pegging graft, be not prone in actual use short circuit yet, the generation of the phenomenons such as grafting dislocation.

A kind of preferred implementation of the present utility model, be coated with 2 or 3 layers of strap layer in described dielectric film.This structure is more reasonable.

Another preferred implementation of the present utility model, be pasted with screen in the outside of described dielectric film.This structure only data wire has good shield effectiveness and antijamming capability.

Another preferred implementation of the present utility model, the interlaced setting of strap in the described strap layer of each layer.It is more reasonable that the strap of this structure is arranged, and is convenient to peg graft use and make.

The accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the flat data wire of the utility model laminated conductor is described in further detail.

Fig. 1 is the cross-sectional view of a kind of embodiment of the flat data wire of the utility model laminated conductor;

Fig. 2 is the A-A generalized section of structure shown in Figure 1.

In figure, 1-strap, 2-dielectric film, 3-screen, 4-strap layer.

Embodiment

The flat data wire of laminated conductor as shown in Figure 1 and Figure 2, some straps 1 are spaced reciprocally rods arranged in horizontal line and become strap layer 4, in dielectric film 2, be coated with 2 layers of strap layer 4 that is parallel to each other and arranges, the strap 1 interlaced ground spread configuration in each layer.The cross section rectangular shaped of strap 1; it is a kind of zinc-plated straight angle copper cash; dielectric film is made by flame-retardant polyester material; have good intensity and pliability; it is the carrier of conductor; be again the insulating protective layer of conductor, this dielectric film 2 is pressed together on the both sides of strap 1 and strap layer 4 by PUR, thereby forms clad structure.Lateral surface at dielectric film 2 posts screen 3 by melt viscosity, the metal copper wire braid that this screen 3 forms for the metal proof copper-wire braided.

Above-mentionedly enumerated preferred implementations more of the present utility model, but the utility model is not limited to this, the utility model also has many improvement and conversion.As the strap layer in dielectric film, being not limited to 2 layers, can also be 2 ~ 10 layers, and preferred 2 layers or 3 layers, the strap of each layer can be both interlaced ground spread configuration, can be also to be oppositely arranged; Screen can also be compound copper-plastics band layer or plastic-aluminum combined belt.
