Description
Technical Field
[0001] The utility model relates to a cable, in particular to a USB interface drag chain cable. Background Art
[0002] At present, for traditional USB interface drag chain cables, the conductors of the core are only made of ordinary conductive metals, with general tensile strength and poor bending properties. After long-term use, it is easy to cause the cable to bend, be difficult to recover, and even break, resulting in a short service life. Therefore, a USB interface drag chain cable is designed to solve the above problems.
[0003] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present utility model. Summary of the Utility Model
[0004] To overcome the deficiencies in the above-mentioned prior art, the purpose of the present utility model is to provide a USB interface drag chain cable.
[0005] To achieve the above purpose and other related purposes, the technical solution provided by the present utility model is: a USB interface drag chain cable, which sequentially includes a transmission unit, a shielding layer, and a sheath layer from the inside to the outside. A ground wire is provided on the inner side of the shielding layer; the transmission unit includes a core one and a core two. The core one is composed of a conductor one and an insulating layer one wrapped around its outer layer. The core two is composed of a conductor two and an insulating layer two wrapped around its outer layer. A filler is provided between the core one and the core two.
[0006] Further, both the conductor one and the conductor two are formed by stranding a category six conductor and Kevlar filaments. In this solution, the conductors of the core are formed by stranding a category six conductor and Kevlar filaments. High-strength and lightweight fiber materials are stranded in the metal material. Due to the high strength and good toughness of this aramid material, compared with traditional metal conductors, this conductor stranded with Kevlar filaments has greater tensile strength, is not easily broken, and has better performance.
[0007] Further, the dosage ratio of the category six conductor to the Kevlar filaments is 8:1 to 12:1. In this solution, the stranding dosage ratio of the category six conductor to the Kevlar filaments is 8:1, 9:1, 10:1, 11:1, or 12:1, which can ensure both the transmission performance and tensile strength of the conductor.
[0008] Further, a wrapping layer is provided between the transmission unit and the shielding layer. In this solution, during the use of the cable, the wrapping layer can wrap the internal wire into a cylindrical shape to prevent the wire from loosening; the wrapping layer can use heat-insulating, anti-corrosive and other materials to play corresponding roles such as heat insulation and anti-corrosion for the cable; the wrapping layer can also play a buffering and padding role; the wrapping layer can make the signal undisturbed and play an insulating role between the transmission unit and the shielding layer.
[0009] Further, the ground wire is arranged between the wrapping layer and the shielding layer. In this solution, the ground wire can play a supporting and fixing role through the wrapping layer and the shielding layer, is not easy to displace, and ensures the stability of the ground wire in the cable structure.
[0010] Further, the material of the wrapping layer is aluminum foil. In this solution, the aluminum foil has strong plasticity, is convenient for wrapping operation, and the aluminum foil is resistant to high temperature. Using aluminum foil for wrapping can improve the performance stability.
[0011] Further, the shielding layer is woven from alloy wires. In this solution, the shielding layer is woven from alloy wires, has good elasticity and is not easy to deform, and also ensures the electromagnetic shielding ability of the cable, and can play a good shielding effect.
[0012] Further, the shielding rate of the shielding layer ≥ 80%. In this solution, the shielding effect is further ensured.
[0013] Further, the thickness of the first insulating layer and the thickness of the second insulating layer are both 0.2 mm - 0.3 mm; the materials of the first insulating layer and the second insulating layer are both FEP. In this solution, using Teflon as the material of the insulating layer, compared with the traditional PE material, the insulating layer can be made relatively thinner, while the strength and elongation rate are both improved, the strength can reach more than 30 MPA, and the bending property is also relatively better.
[0014] Further, the number of the first cores is the same as the number of the second cores, and both are greater than or equal to two. In this solution, the stable transmission of the cable data is ensured, and the stability of the internal structure is also ensured.
[0015] Due to the application of the above technical solutions, the beneficial effects of the present utility model compared with the prior art are:
