Abstract
Description
Technical Field
[0001] This utility model relates to the field of hybrid cable technology, specifically a highly flexible hybrid cable for network communication and power transmission. Background Technology
[0002] In the existing technology, the two pairs of CAT5E wires in the high-flexibility network communication and power transmission hybrid cable with two pairs of CAT5E wires and four core power lines are generally made in two ways: one is to make the two pairs of core wires into a QUAD star strand structure.
[0003] The QUAD star-and-twisted structure has the following two problems:
[0004] 1) Crosstalk control is difficult in QUAD structures, especially in dynamic applications. Once the symmetrical structure is disrupted, crosstalk performance deteriorates.
[0005] 2) For small wire gauges, such as 26AWG and 28AWG, the QUAD structure is too difficult to control in terms of crosstalk performance during manufacturing. Another approach is to directly make two pairs of cables, covered with aluminum-plastic tape and braid. This structure is prone to loose twisting pitch, which leads to a decrease in transmission performance in highly dynamic and flexible applications. Utility Model Content
[0006] The purpose of this invention is to provide a highly flexible hybrid cable for network communication and power transmission to solve the problems in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a highly flexible hybrid cable for network communication and power transmission, comprising a central filling strip for cabling, with two CAT5E cables and four power cables distributed on the outer side of the central filling strip, and peripheral filling strips for cabling between adjacent cables. The central filling strip, CAT5E cables, power cables, and peripheral filling strips for cabling are covered by non-woven fabric wrapping tape, with an aluminum-plastic composite tape layer covering the outer side of the non-woven fabric wrapping tape, a metal braided layer covering the outer side of the aluminum-plastic composite tape layer, and a sheath covering the outer side of the metal braided layer.
[0008] Preferably, the CAT5E cable includes two core wires and two CAT5e twisted-pair filler strips, which are covered by a PTFE substrate and an aluminum-plastic composite tape.
[0009] Preferably, the CAT5e twisted filler strip contains a polyester fiber rope.
[0010] Preferably, the core wire is composed of a CAT5e insulation layer and a CAT5e conductor, and the outer side of the CAT5e conductor is covered with a CAT5e insulation layer.
[0011] Preferably, the power cord cable includes a power cord conductor and a power cord insulation layer, with the power cord conductor covered by the power cord insulation layer.
[0012] Preferably, the metal braided layer is a tin-plated copper wire braided layer.
[0013] Preferably, the sheath is a polyolefin elastic sheath.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By setting up a unique 2-pair CAT5E structure, the problem of unstable crosstalk in conventional QUAD structures in high-flexibility applications is overcome.
[0016] 2. Two filler strips were added to each pair of core wires to enhance the stability and roundness of the core wires in high-flexibility applications.
[0017] 3. Each pair of core wires is shielded with PTFE-based aluminum foil, which avoids the problem of easy breakage of PET-based aluminum foil in high-flexibility applications.
[0018] 4. Polyester fibers with good tensile strength are placed in the middle of the filler strip to prevent the filler strip from being stretched thin during the production process. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0023] Please see Figure 1 In this embodiment of the present invention, a high-flexibility hybrid cable for network communication and power transmission includes a central filling strip 13. Two CAT5E cables and four power cables are distributed on the outer side of the central filling strip 13. A peripheral filling strip 5 is provided between adjacent cables. The central filling strip 13, the CAT5E cables, the power cables and the peripheral filling strip 5 are covered by a non-woven fabric wrapping tape 4. An aluminum-plastic composite tape layer 3 is wrapped on the outer side of the non-woven fabric wrapping tape 4. A metal braided layer 2 is wrapped on the outer side of the aluminum-plastic composite tape layer 3. A sheath 1 is wrapped on the outer side of the metal braided layer 2.
[0024] The CAT5E cable includes two core wires and two CAT5e twisted-pair filler strips 8. The two core wires and two CAT5e twisted-pair filler strips 8 are covered by PTFE substrate and aluminum-plastic composite tape 11. Polyester fiber rope 12 is provided inside the CAT5e twisted-pair filler strips 8. The core wire is composed of CAT5e insulation layer 9 and CAT5e conductor 10. The CAT5e conductor 10 is covered with CAT5e insulation layer 9 on the outside.
[0025] The power cable includes a power conductor 6 and a power insulation layer 7, with the power conductor 6 covered by the power insulation layer 7.
[0026] The metal braided layer 2 is made of tin-plated copper wire braid; the sheath 1 is made of polyolefin elastic sheath. The peripheral filler strip of the cable is made of polyolefin filler strip, and the central filler strip of the cable is made of polyolefin filler rope.
[0027] The core wire extrusion is carried out using high-speed insulation equipment, which effectively controls the concentricity, ellipticity, eccentricity, and insulation outer diameter of the extrusion.
[0028] Twisted Pair: Electromagnetic tension control is used to ensure that the cable moves forward with stable tension and clamping force when the core wire semi-finished product is laid out.
[0029] Cable Assembly: The laying of two pairs of CAT5E semi-finished products and four power cord semi-finished products uses electromagnetic tension control to ensure the cables move forward with stable tension and clamping force. Six polypropylene filler ropes fill the perimeter, and a pre-twisted polypropylene filler is placed in the middle, plus non-metallic non-woven fabric wrapping tape. Filling and wrapping are carried out at a constant tension speed. The non-metallic non-woven fabric wrapping tape ensures the roundness and stability of the cable structure. An aluminum-plastic composite tape shielding layer is wrapped around the non-metallic wrapping tape.
[0030] Braiding: The braided layer tightly wraps the tin-plated copper wire in two layers, 360 degrees, to resist external signal interference; the large-diameter guide wheel ensures that the bending radius of the wire is appropriate during the movement of the wire, so as not to cause stress concentration that affects the wire diameter position and transmission performance; the wire is neatly laid out and prevents abnormal squeezing on the take-up spool to ensure its stable electrical performance.
[0031] Sheath extrusion: Flame-retardant and easily flowing polyolefin materials are used to ensure the flame retardancy and flexibility of the cable products. During the sheath extrusion process, the semi-finished product adopts active wire feeding to ensure that the cable has stable tension. The large diameter wire storage rack ensures that the bending radius of the wire is appropriate during the movement of the wire to avoid stress concentration affecting the wire diameter position and transmission performance. The wire is neatly laid out to prevent abnormal extrusion on the take-up spool, so as to ensure its stable electrical performance.
[0032] The working principle of this utility model is as follows: the CAT5E wire pairs for 100 Mbps transmission are arranged in two pairs, and the twisted wires are filled with filler to ensure the roundness of the diagonal. The aluminum-plastic composite tape with PTFE substrate ensures that it is not easy to break in high-flexibility applications; thus ensuring the transmission performance of the wire in application.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
