Abstract
The utility model provides a transducer extended coaxial data cable device, comprising a data cable; one end of the data cable is provided with a socket connector which is connected with a transducer and the other end thereof is provided with a socket connector which is connected with a PLC controller or a PC machine; the structure of the data cable is the combination of a plurality of coaxial cables; the conductor of each coaxial cable is sequentially covered by a 'skin-froth-skin' three-layer insulation layer, an external conductor layer, a shield layer and an insulation isolation layer; the center of the combination of the coaxial cables is provide with a circular filling bar; the combination of the coaxial cable is externally covered by an external protection sleeve; the transducer extended coaxial data cable device has small transmission attenuation, long transmission distance (achieving 400m), prolongs the effective control distance of the transducer and the controller, has rapid transmission speed, accelerates the response speed of the transducer, and has good shield performance and better anti-interference capability.
Description
Technical field
The utility model relates to a kind of signal-transmitting cable and interface unit, especially coaxial data cable and interface unit.
Background technology
Digital data transmission control is adopted in existing adjusting control to frequency converter, and the prolongation data cable of relevant transmission signals all uses conventional shielding network cable and interface unit, have the following disadvantages: transmission range is short, and then decay is bigger to surpass 100 meters, easily forms misoperation or no signal condition; Transmission frequency is lower, and transmitted data amount is few, can not satisfy the requirement of the multifrequency incremental data amount of frequency conversion data; Data cable intensity is low, easily impaired.
Summary of the invention
The purpose of this utility model provides the frequency converter that a kind of transmission range is long, transmitted data amount is many, intensity is high and prolongs coaxial data cable device.
A kind of frequency converter that the utility model provides prolongs coaxial data cable device, comprise that an end is provided with the connector that is connected with frequency converter, the other end is provided with the data cable of the connector that is connected with PLC controller or PC, the structure of data cable is the combination of several coaxial cables, the conductor of every coaxial cable coats " skin-bubble-Pi " three-layer insulated layer, outer conductor layer, screen, dielectric isolation layer outward successively, coats oversheath outside the combination of coaxial cable.
For making the utility model roundness better, be provided with circular packing in the central authorities of the combination of coaxial cable.
The beneficial effects of the utility model are: the signal transmission attenuation is little, and transmission range is long, can reach 400 meters, has prolonged the effective control distance of frequency converter and controller; Transmission rate is fast, improves the reaction speed of frequency converter, and shielding properties is excellent, and is anti-interference effective.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model, and Fig. 2 is the cross sectional representation of data cable of the present utility model.
In Fig. 1, Fig. 2,1, connect the connector of frequency converter, 2, data cable, 3, connect the connector of PLC controller or PC; 21, conductor, 22,23,24, " skin-bubble-Pi " three-layer insulated layer, 25, circular packing, 26, outer conductor layer, 27, screen, 28, dielectric isolation layer, 29, oversheath.
Embodiment
With reference to Fig. 1, Fig. 2, outside conductor 1, adopt low density polyethylene (LDPE) to coat " skin-bubble-Pi " three-layer insulated layer 22 respectively, 23,24, the outer conductor layer 26 of coated copper wire braiding successively outside insulating barrier 24, aluminium-plastic tape screen 27, polyethylene insulation separator 28 is made coaxial cable, after circular packing 25 is placed by four coaxial cables central authorities, carry out stranded and adopt polyurethane elastomer to coat oversheath 29 and make data cable 2, the connector 1 that will connect frequency converter simultaneously, the connector 3 that connects PC controller or PC is arranged on to extrude when data cable 2 two ends coat oversheath 29 with data cable 2 and fuses, and promptly makes the utility model.
Claims (2)
1, a kind of frequency converter prolongs coaxial data cable device, comprise that an end is provided with the data cable that the connector other end that is connected with frequency converter is provided with the connector that is connected with PLC controller or PC, the structure that it is characterized in that data cable is the combination of several coaxial cables, the conductor of every coaxial cable coats " skin-bubble-Pi " three-layer insulated layer, outer conductor layer, screen, dielectric isolation layer outward successively, coats oversheath outside the combination of coaxial cable.
