Abstract
The utility model relates to a novel rectangular anti-interference shielded cable. In order to solve the defects of the conventional cables, including poor bending property and flexibility and weak anti-electromagnetic-interference capability among wire groups, a rectangular outer sheath is extruded outside the wire groups, wire group-shielding layers, isolating layers or cable-shielding layer of a conventional round anti-interference shielded cable. The utility model has the advantages of good flexibility, easy laying and excellent anti-interference shielding property, the cost can be greatly reduced, and the space for laying the cable can be saved.
Description
Technical field:
The utility model relates to the cable technology field, definite a kind of anti-interference shielding rectangle cable of saying so.
Background technology:
The detecting instrument that the control cable of big machinery, interference free performance are had relatively high expectations uses cable, or the cable major part that occasion such as instrument leads is used all is traditional round cable, when laying, if going the same way, cable lays quantity when too much, can twine mutually between the cable, the bendability of cable and the poor-performing that circumnutates, anti-electromagnetic interference capability is very weak between each line group; Or adopt expensive material cable, cost is increased.
Based on above reason, existing cable exists crooked, the poor performance that circumnutates, the weak shortcoming of anti-electromagnetic interference capability between the line group.
The utility model content:
The utility model is intended to solve the circular anti-interference shielded type cable bending of above-mentioned tradition, the poor performance that circumnutates, and the weak shortcoming of anti-electromagnetic interference capability provides a kind of line group antijamming capability strong between each line group, is easy to lay, and bending property is cable preferably.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of New Anti-interference shielding rectangle cable, it is characterized in that: cable is rectangular, and online group, line set of shield layer, separator or stranding screen extrude the rectangle oversheath outward.
Described line group extrude the rectangle oversheath be meant many to core stranded in groups after not stranding directly tiling extrude the rectangle oversheath.
Described line set of shield layer extrude the rectangle oversheath be meant many to core be twisted into group shield respectively after not stranding directly tiling extrude the rectangle oversheath.
Described line group separator extrude the rectangle oversheath be meant many to core be twisted into group shield respectively extrude behind the separator not stranding directly tiling extrude the rectangle oversheath.
Described stranding screen extrude outward the rectangle oversheath be meant many to core be twisted into group shield respectively extrude separator again stranding shielding back directly tiling extrude the rectangle oversheath.
Described rectangle oversheath is polyvinyl chloride layer, butyronitrile composite layer, fluoroplastic layer or silastic-layer.
Advantage of the present utility model is:
The utility model good bending property is easy to lay, and anti-interference shielding properties is superior, reduces cost significantly and saves the cable laying space.

Embodiment:
The utility model proposes a kind of 1kV of being applicable to and the following rectangle cable that prevents the frequent bending of cable or poor anti-interference and manufacture and design.
Conductor of the present utility model adopts single core and multicore copper conductor, tin-coated copper conductor, insulating barrier can use polyethylene layer (70～140 ℃) respectively according to temperature resistant grade, hand over and practice polyethylene layer (90～160 ℃), fluoroplastic layer (200～260 ℃), silastic-layer (60～180 ℃) etc., wherein polyethylene, the anti-interference shielding rectangle cable of crosslinked polyetylene insulated layer are used for general occasion, are not suitable for crooked occasion; The anti-interference shielding rectangle of fluoroplastic insulation cable is suitable for hot environment to be used, and does not use in crooked occasion as far as possible; The anti-interference shielding rectangle of silicon rubber insulation cable then is suitable for low temperature, high temperature occasion, is very suitable for crooked occasion equally.Line set of shield layer and pull the core screen and adopt copper wire braid shielded, tinned copper wire braid shielded and copper (paper tinsel), aluminium (paper tinsel) shielding and their composite shielding; But copper (paper tinsel), aluminium (paper tinsel) shielding are not suitable for bending property and require outstanding occasion; The occasion of resistance to compression and protection against rodents is used the steel belt layer armouring, at the occasion employing steel wire floor armouring of the special high tensile of performance that circumnutates; But separator and oversheath wide selection polyvinyl chloride layer, butyronitrile composite layer, fluoroplastic layer, silastic-layer etc.But the rectangle oversheath that extrudes is antijamming capability between the splicing thread group both, also can effectively prevent to be used for bending circumnutate phase mutual friction between the occasion line set of shield and lesion wire set of shield and insulated wire cores.
The utility model by the variant line group of the circular anti-interference shielded type cable of tradition is stranded respectively, line set of shield layer, line group separator, cable core screen or cable core stranding after tiling place, extrude sheath with rectangular mould and form.
Embodiment 1: the cable core screen extrudes the rectangle oversheath outward
How in groups stranded respectively to two insulated wire cores or three insulated wire cores, extrude line set of shield layer, separator, stranding belting layer, filler and cable core screen more respectively after, promptly behind the stranding at last again tiling extrude the rectangle oversheath.
Embodiment 2: line group separator extrudes the rectangle oversheath
How in groups stranded respectively to two insulated wire cores or three insulated wire cores, extrude line set of shield layer, separator more respectively, this moment is stranding not, outside separator, extrude simultaneously the rectangle oversheath, extrude finish after, outside oversheath, also can continue to extrude stranding belting layer, filler and cable core screen, last stranding.
Embodiment 3: line set of shield layer extrudes the rectangle oversheath
How in groups stranded respectively to two insulated wire cores or three insulated wire cores, extrude line set of shield layer more respectively, this moment is stranding not, online set of shield layer extrudes the rectangle oversheath outward simultaneously, extrude finish after, outside oversheath, also can continue to extrude separator, stranding belting layer, filler and cable core screen, last stranding.
Embodiment 4: line group layer extrudes the rectangle oversheath
How in groups stranded respectively to two insulated wire cores or three insulated wire cores, this moment stranding not, online group extrudes the rectangle oversheath outward simultaneously, extrude finish after, outside oversheath, also can continue to extrude line set of shield layer, separator, stranding belting layer, filler and cable core screen, last stranding.
