Abstract
The utility model discloses a high temperature resistant and light LVDS data bus cable, characterized in that the outer layer of a high strength silvering copper alloy twisted wire conductor is a fluorinated ethylene propylene insulating layer intertwisted with a filling core made of foaming PTFE micropore belt, the outer layer of the fluorinated ethylene propylene insulating layer is a foaming PTFE micropore belt wrapping layer, and a silvering copper wire woven shield is arranged between the foaming PTFE micropore belt wrapping layer and a fluorinated ethylene propylene sheath. The advantages lie in that the cable has the characteristics of high and low temperature resistance, aging resistance, corrosion resistance, light weight, small external diameter and being capable of providing highly reliable service under server environment, thus being suitable for LVDS signal transmission in aviation electronic field.
Description
Technical field
The utility model is high temperature resistant light-duty LVDS data bus cable, and bus cable has characteristics such as high-low temperature resistant (65 ℃～+ 200 ℃), ageing-resistant, anticorrosive, fire-retardant, in light weight and external diameter be little; Can under rugged environment, provide highly reliable service, be applicable to the LVDS signal transmission in aviation electronics field.
Background technology
At present, domestic do not have a high temperature resistant light-duty LVDS data bus cable, and this cable designs on reference ANSI/TIA/EIA-644-A-2001 " Electrical Characteristics of Low Voltage Differential Signaling (LVDS) " standard, GJB 773A-2000 " Aero-Space fluoropolymer insulated wire cable " basis.What common LVDS data bus cable adopted is the normal temperature material, and high and low temperature resistance is poor; And material extrudes that thickness is thick, and the product external diameter is big, and Heavy Weight needs the bigger space of laying.
Summary of the invention
The utility model proposes a kind of high temperature resistant light-duty LVDS data bus cable, conductor is the silver-plated copper-alloy stranded conductor of high strength, has improved the mechanical strength of cable conductor, solves when assembling the conductor problem of disconnected core easily.Adopt exotic material insulation and sheath, adopt thin-walled to extrude, improved the high and low temperature resistance of cable, reduced external diameter and weight; Adopt expanded PTFE micropore band to fill and wrapped during stranding, improved the flexibility of cable and electric property etc.
Technical solution of the present utility model: its structure is that the skin of the silver-plated copper-alloy stranded conductor conductor of high strength is the perfluoroethylene-propylene insulating barrier, the perfluoroethylene-propylene insulating barrier twists together with adopting the stranded filled core that forms of expanded PTFE micropore band, perfluoroethylene-propylene insulating barrier skin is an expanded PTFE micropore band lapping layer, is the silver-gilt copper wire woven shield between expanded PTFE micropore band lapping layer and perfluoroethylene-propylene sheath.
The utlity model has following advantage: high strength: conductor is the silver-plated copper-alloy stranded conductor of high strength, has improved the mechanical performance of conductor greatly; High temperature resistant: insulation and sheath employing can resistant to elevated temperatures fluoroplastics, and the long-term work temperature can reach+and 200 ℃; Low temperature resistant: cable can also can solve general material because low temperature lays problems such as easily causing sclerosis, embrittlement, thereby satisfy the instructions for use of low temperature environment-65 ℃ of normal laying installations down; High flame retardant, ageing-resistant, corrosion-resistant: adopt fluoroplastics as insulation, filling and sheath material, this kind material has very high fire resistance, ageing-resistant and decay resistance; Stability: add PTFE micropore band and fill between insulated wire cores, make the product electric performance stablity, the structure rounding is stable.Light-duty: external diameter is little, in light weight, is convenient to install lay; Anti-interference: as to adopt the silver-gilt copper wire woven shield, improved interference free performance; The electrical property excellence: applicable and LVDS high speed data transfer have advantages such as impedance stabilization, decay are little, electric performance stablity.
