Description

Laminated Conductor Flat Data Cable

technical field

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

Background technique

Flexible flat data cable is a kind of signal transmission component, which has the advantages of arbitrary deflection and high-speed signal transmission. The number and spacing of wires can be selected arbitrarily, and the connection is more convenient, which greatly reduces the volume of electronic products, reduces production costs, and improves production efficiency. . It is widely used between moving parts and motherboards, between PCB boards and PCB boards, as data transmission cables in miniaturized electrical equipment, and is almost ubiquitous in modern electrical equipment.

Existing flat data lines mainly include flat conductors, insulating layers and other parts. The flat conductors are made of flat copper conductors, and the insulating layer is made of PET insulating material. Several flat copper conductors are arranged in parallel and covered in the insulating layer. However, the existing structure is a single-layer conductor structure. In order to limit the total width of the data line and save the space occupied by the flat data line, the distance between the conductors is often 0.3mm~1.0mm. The single-layer conductor flat data flexible flat cable not only increases the difficulty of the production of the cable itself, but also makes it difficult to manufacture the connectors that are plugged into it, and is prone to short circuits or contact misalignment during actual use and plug-in assembly. And other abnormal phenomena, resulting in signal transmission failure.

Utility model content

In view of the above-mentioned technical problems existing in the prior art, the technical problem to be solved by the utility model is to provide a flat data line with laminated conductors which has a large conductor spacing and is easy to manufacture.

In order to solve the above-mentioned technical problems, the multilayer conductor flat data line of the present invention includes a flat conductor and an insulating film, and several flat conductors are arranged at intervals to form a flat conductor layer, and the flat conductor layer is covered in the insulating film. At least two flat conductor layers are covered in the insulating film.

In the above structure, since the insulating layer is coated with multiple layers of flat conductor layers, the signals transmitted by the flat conductors in the data line with the laminated conductor structure can be set in a limited cross-sectional space. There are many flat conductors without increasing the overall width of the flat data lines. Compared with the existing flat data lines, under the same line width conditions, the distance between the conductors can be set larger, which is not only convenient for data lines It is also convenient for the manufacture and production of plug-ins that are plugged with each other, and it is not easy to appear short circuit, plug-in misplacement and other phenomena in actual use.

In a preferred embodiment of the present invention, the insulating film is coated with 2 or 3 flat conductor layers. The structure is more reasonable.

In yet another preferred embodiment of the present utility model, a shielding layer is pasted on the outer side of the insulating film. This structure only has good shielding effect and anti-interference ability for data lines.

In yet another preferred embodiment of the present invention, the flat conductors in the flat conductor layers of each layer are arranged alternately. The arrangement of the flat conductors in this structure is more reasonable, and it is convenient for plug-in use and manufacture.

Detailed ways

As shown in Fig. 1 and Fig. 2, several flat conductors 1 are arranged in a straight line at intervals to form a flat conductor layer 4, and the insulating film 2 is coated with two layers of flat conductors arranged in parallel to each other. Layer 4, the flat conductors 1 in each layer are arranged alternately. The flat conductor 1 has a rectangular cross-section and is a tinned flat-angle copper wire. The insulating film is made of flame-retardant polyester material with good strength and flexibility. It is not only the carrier of the conductor, but also the insulating protective layer of the conductor. The insulating film 2 is bonded to both sides of the flat conductor 1 and the flat conductor layer 4 by hot melt adhesive, thereby forming a covering structure. The outer surface of the insulating film 2 is pasted with a shielding layer 3 by hot melt adhesive, and the shielding layer 3 is a metal copper wire braid formed by braiding metal copper wires.

Some preferred embodiments of the present utility model have been enumerated above, but the utility model is not limited thereto, and the utility model also has many improvements and transformations. For example, the flat conductor layer in the insulating film is not limited to 2 layers, but can also be 2 to 10 layers, preferably 2 layers or 3 layers, and the flat conductor layers of each layer can be arranged alternately or opposite to each other; the shielding layer It can also be a copper-plastic composite tape layer or an aluminum-plastic composite tape layer.
