Description
Technical Field
The utility model relates to a wire and cable field, in particular to PROFIBUS DP bus cable for the communication of equipment level control system and distributed IO.
Background
The PROFIBUS DP is an internationalized and open field bus standard independent of equipment manufacturers, is the most widely applied field bus technology in the world, is suitable for communication between an automation system and a field signal unit, can be directly connected with a frequency converter with an interface, an actuator, a transmission device and other field instruments and equipment, and is widely suitable for automation in manufacturing industry, industrial automation in process, automation in other fields such as building, traffic power and the like. The PROFIBUS DP is not only suitable for communication between an automation system and a field signal unit, but also can be used for directly connecting a transmitter with an interface, an actuator, a transmission device and other field instruments and equipment to acquire and monitor field signals, and replaces a large amount of traditional transmission cables with a pair of twisted-pair wires, thereby greatly saving the cost of the cables and correspondingly saving the maintenance time and cost after construction debugging and system commissioning. According to statistics, the total construction cost can be reduced by 20-40% by using PROFIBUS DP.
At present, bus cable manufacturing technology still has certain not enough, and equipment such as multiaxis industrial robot often need remove to lay, drag the use, and long-time back of using causes the cable ageing very easily, and the condition such as conductor contact failure takes place.
Disclosure of Invention
In view of the technical problem that exists among the prior art, the utility model provides a simple structure, tensile strength is strong, the PROFIBUS DP bus cable of the installation of being convenient for, in use, the signal is through the transmission of the insulating core of a pair of transposition, has replaced traditional many cable transmission, has not only saved manufacturing cost, has also correspondingly saved maintenance time and expense after construction debugging and the system of commissioning.
The utility model discloses a realize above-mentioned purpose, the technical scheme who takes is: a PROFIBUS DP bus cable which characterized in that: the cable comprises an insulating cable core, a polyvinyl chloride filling isolation layer, an aluminum foil composite tape sub-shielding layer, a total shielding layer, a paper tape and a polyurethane sheath;
the two insulated wire cores are twisted oppositely, a polyvinyl chloride filling isolation layer and an aluminum foil composite tape shielding layer are sequentially arranged on the insulated wire cores, the aluminum faces outwards, and a total shielding layer, a paper tape and a polyurethane sheath are sequentially arranged outside the insulated wire cores;
the insulating wire core is formed by twisting a plurality of tinned soft copper strands into an inner conductor, and a double-layer co-extrusion one-step-formed foamed polyethylene insulating layer and a polyethylene insulating layer are arranged outside the inner conductor.
Compared with the prior art, the utility model provides a PROFIBUS DP bus cable has following beneficial effect:
1. the whole cable uses the aluminum foil composite belt to divide the shielding layer and the total shielding layer to form the composite shielding layer, which can effectively shield the interference of low-frequency signals and high-frequency signals.
2. The double-layer co-extrusion one-step forming foamed polyethylene insulating layer and polyethylene insulating layer structure is adopted outside the insulated wire core, namely, the wire core insulation adopts a physical foaming and double-layer co-extrusion foam-skin structure, so that the characteristic impedance stability of the cable is ensured and the impedance reaches 150 ohms.
3. Two insulation core twist towards outer isolation layer structure of packing of polyvinyl chloride that sets up, make the utility model discloses have very high stability, even twist reverse for a long time, pull the use, also can guarantee the relative position of sinle silk, both guaranteed sinle silk characteristic impedance's stability, played the physics additional strengthening again, still guaranteed bus cable's long-time back of using, the excellence of performance during the communication.
4. The sheath adopts the polyurethane material, can protect the cable to use under the environment of immersion oil, can effectually prevent the cable surface fracture, has increaseed the tensile ability and the physical and mechanical properties of cable simultaneously, can let the environment of the many oils of cable adaptation, has enlarged the application range of cable, has improved the life of cable greatly.
