Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, and more specifically, to a flat cable. Background Technology
[0002] Wires and cables can be used to transmit electrical energy and signals. A cable consists of a wire sheath and a wire conductor, which are separate. Most wires and cables have a circular cross-section and are single-core cables. They are unsuitable for equipment with flat or molded shapes, and circular cables are the most common.
[0003] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content
[0004] The purpose of this utility model is to provide a flat cable that surpasses traditional cables in terms of safety, reliability, and intelligence.
[0005] This utility model provides a flat cable, including a first core group, a second core group, and a flame-retardant sheath; a second core group is provided on both the left and right sides of the first core group, and the flame-retardant sheath is wrapped around the first core group and the second core group.
[0006] Furthermore, the second core wire assembly includes a second tinned copper wire conductor and a second silicone rubber insulation layer, the second silicone rubber insulation layer being wrapped around the surface of the second tinned copper wire conductor.
[0007] Furthermore, the first core wire assembly includes a first tinned copper wire conductor, a first silicone rubber insulation layer, and a Teflon insulation layer; the first silicone rubber insulation layer contains six of the first tinned copper wire conductors, and the Teflon insulation layer is wrapped around the surface of the first tinned copper wire conductors.
[0008] Furthermore, the flame-retardant sheath is a flame-retardant polyvinyl chloride sheath.
[0009] The flat cable provided by this utility model achieves high reliability in extreme environments through complementary material design (flame-retardant PVC + silicone rubber + Teflon) and a compact, filler-free structure; physical isolation between power transmission and signal control reduces interference; the silicone rubber sheath + Teflon core wire covers a wide temperature range of -60℃ to 260℃; the elimination of filler material makes it suitable for mobile devices and precision instruments; this structure has significant competitiveness in fields such as Industry 4.0, new energy, and deep-sea exploration.

Specifically, the flame-retardant sheath 300 is a flame-retardant polyvinyl chloride sheath.
[0025] Further reference Figure 2 The second core wire group 200 of this utility model includes a second tin-plated copper wire conductor 210 and a second silicone rubber insulation layer 220, the second silicone rubber insulation layer 220 being wrapped around the surface of the second tin-plated copper wire conductor 210.
[0026] The first core wire group 100 of this utility model includes a first tinned copper wire conductor 110, a first silicone rubber insulation layer 120 and a Teflon insulation layer 130; the first silicone rubber insulation layer 120 encloses six of the first tinned copper wire conductors 110, and the Teflon insulation layer 130 is wrapped on the surface of the first tinned copper wire conductors 110.
[0027] It should be noted that the flame-retardant sheath 300 is made of flame-retardant polyvinyl chloride material, which has very strong self-extinguishing safety performance, good pressure resistance and impact resistance; it is very soft and resistant to bending; and has excellent acid and alkali corrosion resistance. The first silicone rubber insulation layer 120 and the second silicone rubber insulation layer 220 are both silicone rubber insulation layers with excellent electrical insulation and stability, extremely wide temperature range, excellent water repellency and weather resistance, high safety and flame retardancy, and good flexibility and sealing performance. They can effectively solve a series of problems of cables under extreme temperatures, complex electric fields, harsh weather and special safety requirements.
[0028] Teflon insulation layer 130 is Teflon insulation, which can ensure the quality of high-frequency signal transmission, improve the fire safety level of the cable, facilitate the cable laying in conduit, and reduce wear; it effectively solves a series of key problems of cables under high-speed signal transmission, extreme temperature, chemical corrosion, high voltage and special safety requirements.
[0029] The first tinned copper wire conductor 110 and the second tinned copper wire conductor 210 are tinned copper wires that are corrosion resistant, prevent insulation deterioration, improve mechanical properties and heat dissipation, and are widely used in applications requiring high flexibility and environmental resistance.
