Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

As shown in fig. 1, the HDMI cable based on FEP material of the present invention includes a plurality of core wires 8, wherein each core wire 8 includes a conductive core material 10 and a first insulating layer 12 wrapping the conductive core material 10. The conductive core material 10 is formed by twisting 19 fine copper wires, and has good conductivity, flexibility and tensile strength. The core structure of the multi-core also increases the tensile resistance to fracture.

The first insulating layer 12 is made of FEP material; FEP, known collectively as Fluorinated ethylene propylene, translates to Fluorinated ethylene propylene copolymers, which can be used as insulation with lower tensile strength, abrasion resistance, and creep resistance than many engineering plastics. It is chemically inert, having a low dielectric constant over a wide range of temperatures and frequencies; and has better fireproof performance.

The twisted pair cable comprises 4 groups of core wires, wherein each two of the 4 groups of core wires are combined into a twisted pair cable 14, a second insulating layer 16 is wrapped outside the twisted pair cable 14, and the second insulating layer 16 is made of MYLAR. MYLAR refers to a tough polyester polymer which has good insulating property and good bonding degree with FEP materials, and the damage caused by mutual friction is avoided.

The gaps of the 4 twisted pairs of wires 14 are respectively provided with 1 bare copper wire 28 twisted by a plurality of strands of fine copper wires, and the total number of the bare copper wires 28 is 4 to be used as the ground wire. The tensile ropes 18 beside the peripheral sub-wires of the 4 groups of twisted pair wires 14 can be made of steel wires or Kevlar. Especially, the rope made of Kevlar with high strength, softness and insulation is better, and the rope and the insulating layer have better bonding performance, so that the damage of the steel wire rope to the insulating layer can be effectively avoided. Tensile rope 18 evenly distributed helps improving the holistic pull resistance of HDMI cable, avoids the not enough condition of local pull resistance. The remaining cords are disposed adjacent the tensile strand 18 to help protect the cords from high tensile forces.

The anti-stretching rope is characterized by further comprising a third insulating layer 20 wrapping all the core wires and the anti-stretching ropes 18, wherein the third insulating layer 20 is made of MYLAR; the third insulating layer 20 is wrapped with a woven layer 22, the woven layer 22 is wrapped with 26 cotton paper isolation layers, and 26 is wrapped with an outer cover 24 made of PUR material. MYLAR refers to a tough polyester polymer, PUR is polyurethane, which provides good physical and insulating properties.

The braid 22 is braided from multiple strands of ultra-fine copper wire, which is tinned copper to shield electromagnetic interference.

An isolation water absorption layer 26 made of cotton paper is arranged between the weaving layer 22 and the outer cover 24, so that the effects of water absorption and water storage are achieved, the weaving copper wire is not damaged when the outer cover is cut off, and the service life of the cable is prolonged.
