Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a unit structure of an extruded fixed straight-wrapped shielded high-frequency cable signal. Background Art

[0002] With the advancement of technology, humans are increasingly dependent on information and communication products. The amount of information transmitted in the instruction cycle of information electronic products has increased significantly, and the high-frequency characteristics of electronic components have become increasingly important. The corresponding signal cable speed is also constantly increasing, and the required frequency requirements are also being continuously improved.

[0003] There are currently two types of existing 30G and above transmission line structures in the industry: Figure 1 The first type is a 2-signal line straight shielding layer, using wrapping as the main means of fixing the shielding layer; refer to Figure 2 The second is to arrange multiple signal lines in parallel and then laminate them on both sides with shielding material. Both methods can reach 30GHz, but the two cables have their own disadvantages. The first structure is that the pitch pattern of the wrapping will cause the resonance high-frequency attenuation to have a spike. The performance of the second cable will deteriorate a lot after bending, and the application scenarios of the product are limited. Utility Model Content

[0004] The utility model aims to provide a unit structure for extruding and fixing a direct-wrapped shielded high-frequency cable signal, so as to overcome the shortcomings in the prior art.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a unit structure of an extruded fixed straight-wrapped shielded high-frequency cable signal, including a conductor layer, an insulating layer is arranged outside the conductor layer, a wound shielding layer is arranged outside the insulating layer, and an extruded fixing layer is arranged outside the shielding layer.

[0006] In the above scheme, an extruded fixing layer is used to fix the shielding layer. The fixing layer formed by the extrusion pattern can not only tightly wrap the shielding layer, but also fix the pitch texture produced by the shielding layer, thereby solving the problem that the pitch texture of the wrapping will cause the resonant high-frequency attenuation to have spikes. At the same time, the fixing layer formed by the extrusion pattern will not produce pitch texture, thereby solving the problem that the performance of the cable will deteriorate a lot after bending due to the double-sided bonding of the shielding material, and the application scenarios of the product are limited.

[0007] As an improvement of the unit structure of an extruded fixed straight-sheathed shielded high-frequency cable signal of the utility model, the fixing layer is extruded from FEP plastic material or TPX plastic material.

[0008] In the above scheme, the fixing layer extruded from FEP plastic material or TPX plastic and other materials can not only tightly wrap the shielding layer, but also the thickness of the extruded fixing layer is basically consistent and is integrated. In this way, even if the cable is bent, the fixing layer also has a certain tensile resistance and bending resistance, thereby ensuring the overall strength of the cable.

[0009] As an improvement of the unit structure of an extruded fixed straight-wrapped shielded high-frequency cable signal of the utility model, the shielding layer is formed by longitudinally wrapping aluminum foil or copper foil.

[0010] In the above solution, the shielding layer formed by winding aluminum foil or copper foil is used for electromagnetic shielding to improve the stability of signal transmission.

[0011] As an improvement of the unit structure of an extruded fixed straight-wrapped shielded high-frequency cable signal of the utility model, the insulating layer is extruded from FEP plastic material or PE plastic material.

[0012] In the above scheme, the insulating layer is used for insulation treatment between the conductor layers. At the same time, the insulating layer extruded from FEP plastic material or PE plastic material can maintain a stable spacing between the conductor layers, and the insulating layer and the conductor layer are integrally arranged to maintain the overall strength between the conductor layer and the insulating layer.

[0013] As an improvement of the unit structure of an extruded fixed straight-wrapped shielded high-frequency cable signal of the utility model, the conductor layer is made of silver-plated copper material.

[0014] In the above solution, the conductor layer made of silver-plated copper material has better signal transmission performance.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the fixed layer formed by the extrusion pattern can not only tightly wrap the shielding layer, but also will not produce pitch lines, thus solving the problem that the pitch lines of the wrapping will cause peaks in the resonant high-frequency attenuation. At the same time, the fixed layer formed by the extrusion pattern solves the problem that the performance of the cable will deteriorate a lot after bending due to double-sided bonding of the shielding material, thus limiting the application scenarios of the product.
