Abstract
The utility model discloses a halogen-free low-smoke polyolefin bus cable applied to a CAN (controller area network), belonging to the technical field of cables. The halogen-free low-smoke polyolefin bus cable comprises a cable core and an outer protection sleeve, wherein the cable core is composed of two pairs of twisted shielding wires; a gap between the cable cores is filled with a polypropylene filler yarn; an aluminum plastic compound shielding belt is wound outside the cable core and forms a total shielding layer with a weaved tin-plated copper wire shielding net; the coverage rate of the total shielding layer is more than 90%; and the thermo-plastic halogen-free low-smoke polyolefin outer protection sleeve is extruded on the total shielding layer. The twisted shielding wires are formed in such a way that twisted wires of two insulated wire cores are wound with a polyester belt and the aluminum plastic compound shielding belt in sequence, and 7 strands of tin-plated copper wire bundle drainage wires are arranged between the polyester belt and the aluminum plastic compound shielding belt. The insulated wire cores are formed in such a way that a solid core polyolefin insulator is extruded outside a multi-strand tin-plated soft copper wire bunched conductor. The halogen-free low-smoke polyolefin bus cable applied to the CAN is reasonable and simple in structure, easy to manufacture and low in cost, and has the advantages of excellent transmission performance, environmental friendliness, non toxicity, long service life and the like.
Description
Technical field
The utility model relates to a kind of structure of cable, and especially the structure of the bus cable used of controller local area network belongs to the cable technology field.
Background technology
Continuous development along with science and technology; Bussing technique all more and more comes into one's own at all spectra of commercial Application; The parallel line method that tradition is used for machine and equipment does not have flexibility, causes time-consuming and poor efficiency, and being used for of bus system practiced thrift cost and opened wide door with strengthening the property.The cable performance that is applied to the CAN bus directly influences its transfer of data, and is very high to the specification requirement of cable itself, like low electric capacity, decay is little, shielding strong, environmental protection, nontoxic, low cigarette, fire-retardant etc.
Summary of the invention
The purpose of the utility model is exactly the needs to above-mentioned market, a kind of low electric capacity is provided, decay is little, shielding is strong, environmental protection, nontoxic, hang down cigarette, the fire-retardant low smoke, zero halogen polyolefin bus cable that is applied to CAN.
The purpose of the utility model is to realize like this; Be applied to the low smoke, zero halogen polyolefin bus cable of CAN, comprise cable core and oversheath, it is characterized in that said cable core is made up of two pairs of pair twist shielding conductors; Filled polypropylene gasket for packing in the gap of cable core; The outer wrapped plastic-aluminum combined mask tape of cable core adds braiding tinned copper wire gauze screen and constitutes total screen, and total screen coverage rate extrudes thermoplastic halogen-free and low-smoke polyolefin oversheath greater than more than 90% on total screen.
Said pair twist shielding conductor is by wrapped successively polyester belt and plastic-aluminum combined mask tape on the twisted pair wire of two insulated cores, and 7 strands of tin-coated copper tow drain wires are set between polyester belt and plastic-aluminum combined mask tape constitute.
Said insulated wire cores is closed conductor by the zinc-plated soft copper tow of multiply and is extruded real core polyolefin insulating outward and constitute.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and it is good to have transmission performance, environment-protecting asepsis, advantages such as long service life.This cable carries out system's improvement and upgrading to its process structure and material on the basis of normal cable, its conductor adopts the zinc-plated soft copper tow of multiply to close, and makes conductor oxidative phenomena can not take place.Conductor extrudes real core polyolefin insulating outward, and its performance satisfies the requirement of YD/T 760 standard codes, has low electric capacity, low decay property.Cable core is made up of two pairs of pair twist shielding conductors, and the design of pair twist pitch meets the transmission performance requirement.All first wrapped polyester belt behind the insulated wire cores pair twist, wrapped more plastic-aluminum combined mask tape, and 7 strands of tin-coated copper tow are set as drain wire in plastic-aluminum combined mask tape, four insulated cores of two pairs of pair twist shielding conductors adopt four kinds of different colours respectively, to show differentiation.Filled polypropylene gasket for packing in the cable core gap of cable, cable core is outer to add total screen that the close net braiding of tinned copper wire constitutes by plastic-aluminum combined mask tape, and shielding covers greater than more than 90%, strengthens shielding action greatly, improves the cable interference free performance.The oversheath of cable adopts the thermoplastic halogen-free and low-smoke polyolefin jacket material, generally adopts grey or blueness, convenient identification, and this kind material has environmental protection, nontoxic, low cigarette, premium properties such as fire-retardant, and index meets the RoHS of European Union environmental protection command request.
