Abstract
The utility model discloses a special high voltage-resisting miniature power cable. The special high voltage-resisting miniature power cable comprises an inner conductor; the exterior side of the conductor is wrapped with an insulating layer, an outer conductor, an inner sheath, a shielding layer and an outer sheath successively from inside to outside; a ceramic fire-proof fire-resistant composite belt layer is leftwards wrapped between the inner conductor and the insulating layer, the overlapping rate of the ceramic fire-proof fire-resistant composite belt layer is more than 50%; a plurality of layers of tinned copper wires are braided to form the outer conductor; the cross section of the outer conductor is the same with that of the inner conductor; and the braiding density of each layer of the of tinned copper wires reaches more than 85%. The special high voltage-resisting miniature power cable of the utility model has the advantages of high temperature resistance, high voltage resistance, compact structure, reduction of installation space, reduction of vehicle load weight, improvement of electromagnetic compatibility, electric strength and softness, and insurance of stable and reliable communication quality in harsh strong electromagnetic occasions and high voltage occasions.
Description
Technical field
The utility model relates to the electronic information intelligent transport technology, is specifically related to a kind of fire-retardant, oil resistant, anti-electromagnetic wave that connects for the vehicle electronic device emission system that crucial matching component selects for use and disturbs extraordinary high pressure resistant miniature power cable.
Background technology
Anti-electromagnetic wave disturbs, high pressure resistant power cable, when designing this specific character cable in the past, (1) at first select for use 2 very big leads of cross section to transmit, make that like this structure of whole cable is very huge, the weight of cable also increases thereupon, pliability is poor, brought many difficulties for installation and use, (2) another kind is selected the structure of coaxial cable for use, outer conductor only plays the effect of bonding, can not use as the return path signal line, environment is restricted and use the structure more than adopting obviously just can not satisfy instructions for use as return line laying, in this special environment, use anti-anti-electromagnetic wave to disturb with high voltage bearing power cable and just proposed new research topic to us, at new problem from material, structural design is fully analyzed and is proved to processing technology, in order to satisfy the compatible and high voltage bearing instructions for use of special electromagnetic, not only material is carried out preferably simultaneously structure being optimized, adopt two sheaths (increase inner sheath) by anatomizing comparative structure, outer conductor adopts multi-layer braided design to novel fire-retardant, oil resistant, anti-electromagnetic wave disturbs extraordinary high pressure resistant miniature power cable to develop.
Summary of the invention
The purpose of this utility model, in same cable, transmit signal back and forth, for vehicle-mounted ejection system provides a kind of novel high temperature resistant, high pressure resistant miniature power cable, this cable is by preferred material and optimizing structure, make product with compact structure, reduce to lay the space, alleviate vehicle load, improve Electro Magnetic Compatibility, electric strength and the pliability of product simultaneously, in the strong-electromagnetic field and high-tension occasion of harshness, guarantee that the reliable and stable anti electromagnetic wave of communication quality disturbs extraordinary high pressure resistant miniature power cable.
To achieve the above object, the utility model adopts following design:
Extraordinary high pressure resistant miniature power cable is characterized in that: include inner wire, the inner wire outside is coated with insulating barrier, outer conductor, inner sheath, screen, oversheath from inside to outside successively; Also be surrounded with the fire-resistant composite band of one deck pottery chemoprevention fire between described inner wire and the insulating barrier, direction is left-hand, and the rate of putting up is more than 50%; Outer conductor is formed by the braiding of multilayer tinned wird, and the outer conductor cross section is identical with inner wire, and every layer of count reaches more than 85%.
The high pressure resistant miniature power cable of described special type is characterized in that: described inner wire is by multiply tin-coated copper wire harness, stranded forming.
The high pressure resistant miniature power cable of described special type is characterized in that: described insulating barrier adopts thermoplastic elastomer (TPE).
The high pressure resistant miniature power cable of described special type is characterized in that: described inner sheath, oversheath all adopt butyronitrile PVC compound.
The high pressure resistant miniature power cable of described special type is characterized in that: described screen is to be formed by the tinned wird braiding.
Useful technique effect of the present utility model is:
1, outer conductor adopts this novel braiding structure than the structure of former 2 leads, and finished size has reduced about 30%, and detailed dimensions sees Table 1, and overall weight also reduces thereupon.
2, because the cross section of power cable is bigger, inner wire selects that solderability is good, conductor adopts multiply restraint earlier the processing mode that afterwards twists twocouese for use, not only softness, good bandability, structure rounding, not yielding, while steady signal transmission.
3, in order to strengthen ampacity, improve thermal stability and high pressure resistant, insulation is combined with extrusion molding by wrapped, the fire-resistant composite band of wrapped one deck pottery chemoprevention fire outside inner wire at first, this novel ceramic formed material has formed a kind of adamantine housing when temperature is very high, outside lapping layer, extruded one deck thermoplastic elastomer (TPE), the thermal endurance height of this material, elasticity excellence organically in conjunction with as insulation, have improved the stability of signal transmission with two kinds of materials.
4, outer conductor adopts the strong tinned wird of resistance to corrosion as signal transmssion line, through multi-layer braided forming, the cross section is equal to the inner wire cross section, as the loop, reduces the physical dimension of cable, this compact conformation reduces to lay the space, improves the pliability of cable simultaneously.
5, this novel anti-electromagnetic wave interference, high pressure resistant miniature power cable, superior performance, high thermal stability, high pressure resistant, light weight and conserve space, in special environment, do not influence communication quality, be the first-selected product of the crucial matching component of present vehicle electronic device ejection system.
