Description

Technical Field

[0001] This utility model relates to the field of shielded cable technology, and more specifically, to a twisted-pair shielded computer cable. Background Technology

[0002] Against the backdrop of rapid development in industrial automation, information technology, and smart buildings, reliable data transmission has become the nerve center for the stable operation of modern systems and equipment. Twisted-pair shielded computer cables are a key fundamental component that has evolved under this macro-level demand for extremely high data integrity and transmission reliability.

[0003] Currently, to achieve high shielding effectiveness at high frequencies (resisting external electromagnetic interference (EMI) and preventing internal signal leakage), shielded cables typically employ thick metal braided layers or composite aluminum foil-braided layers. However, this results in cables with high rigidity and poor flexibility. When repeatedly bent and folded in the confined space of a data center, fatigue damage can easily occur, and the shielding layer may even break, leading to shielding failure.

[0004] To address the aforementioned issues, this application proposes a twisted-pair shielded computer cable. Utility Model Content

[0005] The purpose of this invention is to provide a twisted-pair shielded computer cable that solves the problem of easy breakage and failure of the cable shielding layer in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A twisted-pair shielded computer cable, comprising a cable;

[0008] The cable consists of a conductor and a sheath, with a dynamic shielding layer between the conductor and the sheath.

[0009] The conductor core contains twisted pairs of wires.

[0010] The dynamic shielding layer has a multi-layer structure, consisting of a baseband, a buffer strip, a shielding mesh, and a shielding strip from the inside out.

[0011] The outer side of the baseband is fixed with a semi-circular protrusion, and a positioning groove is formed between adjacent circumferential protrusions.

[0012] Preferably, the protrusion has a porous structure and is spirally wrapped around the outside of the conductor core along with the baseband.

[0013] Preferably, the buffer strip is spirally wound inside the positioning groove.

[0014] Preferably, the inner side of the shielding mesh abuts against the protrusion, forming a cavity between it and the buffer strip.

[0015] Preferably, the shielding tape is spirally wrapped around the outside of the shielding mesh to cover the gaps in the shielding mesh.

[0016] Preferably, the porous structure of the protrusion provides space for the bending deformation of the shielding mesh.

[0017] Preferably, the bending of the cable causes the adjacent protrusions to squeeze the buffer strip, and the elastic force of the buffer strip forms a reset.

[0018] The beneficial effects of this utility model are:

[0019] 1. By setting up a dynamic shielding layer, the deformation of the shielding mesh can be reduced when the cable is bent by using protrusions and positioning grooves, thereby achieving a shielding effect that still maintains 100% coverage after bending, and also avoiding the problem of easy breakage under frequent bending deformation.

[0020] 2. Through the porous structure of the protrusion and the filling of the buffer strip, it can form a linkage elastic buffer and stress relief when the cable is squeezed by external force, and promote the recovery of the cable's pressure deformation area, thereby protecting the integrity of the cable and shielding structure and maintaining stable shielding performance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] A twisted-pair computer shielded cable is designed to maintain the stable shielding performance of the cable 1. It achieves a stable shielding effect in a bent state by using a multi-layered staggered structure inside and outside the dynamic shielding layer 13, and by using the protrusions 1311 and positioning grooves 1301 to provide movement space to reduce the amount of deformation. Finally, the buffer strip 134 forms a reverse thrust after deformation to promote recovery, thereby achieving a stable shielding effect in a bent state, preventing breakage and stabilizing the structure, and also achieving a self-healing effect of the structure.

[0031] In some embodiments, the specific structure of the twisted-pair shielded computer cable is as follows: Figure 1-4 As shown, it includes cable 1;

[0032] Cable 1 includes a conductor 11, a sheathing layer 12, and a dynamic shielding layer 13;

[0033] Among them, the conductor core 11 is the filling material, and the inside consists of multiple twisted pairs 111;

[0034] Furthermore, the dynamic shielding layer 13 has a multi-layered structure and is disposed between the conductor core 11 and the covering layer 12;

[0035] The dynamic shielding layer 13 includes a baseband 131, a shielding mesh 132, a shielding strip 133, and a buffer strip 134, which are distributed sequentially from the inside to the outside.

[0036] Among them, the baseband 131 is a functional composite tape, the inner layer of which is aluminum foil to provide initial shielding, and the outer layer is a semi-circular protrusion 1311 made of elastomeric foam material.

[0037] Furthermore, the preferred elastic foam material is EVA foam or PE foam;

[0038] Furthermore, the protrusion 1311 is a rib with a porous structure.

[0039] The shielding mesh 132 is woven from tin-plated copper wire on the outside of the baseband 131;

[0040] A positioning groove 1301 is formed between the inner side of the shielding mesh 132 and the outer side of the baseband 131.

[0041] Furthermore, a prefabricated buffer strip 134 is spirally wrapped inside the positioning groove 1301, and the thickness of the buffer strip 134 is approximately half the radial thickness of the protrusion 1311.

[0042] Furthermore, the buffer strip 134 is made of polyurethane or silicone rubber, and after being spirally wrapped around the base strip 131, it is then filled into the interior of the positioning groove 1301.

[0043] The shielding tape 133 is spirally wrapped around the outside of the shielding mesh 132, and is made of aluminum-plastic composite foil with the metal side facing outward;

[0044] It should be noted that the baseband 131, shielding strip 133, and buffer strip 134 are all pre-prepared components, assembled to the outside during the transmission of the core 11, and finally enter the extruder together to form the outermost covering layer 12.

[0045] In some public disclosures, the specific applications of twisted-pair shielded computer cables are as follows: When the cable 1 bends and deforms, the shielding mesh 132 presses against the protrusion 1311, causing the protrusion 1311 to deform, thereby preventing the bending force from pulling the shielding mesh 132 and causing its gaps to expand; the bent and deformed cable will exert a compressive force on the buffer strip 134, causing it to shrink inward, and then when the bending force disappears, the buffer strip 134 will promote the cable and shielding mesh 132 to recover through elastic force, maintaining the stability of the structure; in addition, when the shielding mesh 132 bends and deforms, the shielding tape 133 covers its outer surface, further sealing the gaps, thereby achieving a fully covered shielding effect.
