Continuous development along with the communication technology; The frequency of utilization of mobile communication and radio frequency sensing signal is in continuous lifting; The limited problem of the transmission of high-frequency signal in complex environment highlights day by day, and the important function of leaky coaxial cable in particular surroundings also day by day paid close attention to by people.
The leaky coaxial cable of existing structure has limited its extensive use because manufacturing process is complicated, production cost is high.The present invention is on the insulation heart yearn of existing coaxial cable; Changed the materials used of its outer conductor; And adopt brand-new production technology mode, and greatly reduced the type production cost of products and manufacture difficulty, be a kind of efficient, stable design mode of production of New Type of Leaky Coaxial Cables.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of manufacturing process simple, the wrapped outer conductor leaky coaxial cable of good mechanical property novel double-layer more.
Technical scheme of the present invention is:
Cable outer conductor of the present invention adopts copper (aluminium) to mould composite membrane, and double-deck wrapped mode is adopted in the outer conductor coating, and wrapped structure is that the juxtaposition formula is wrapped.
The wrapped outer conductor leaky coaxial cable of a kind of novel double-layer; Comprise successively from inside to outside along center conductor, fluid insulation, outer conductor and the protective sleeve of the central axis longitudinal extension of cable; Wherein fluid insulation separates center conductor and outer conductor; Said outer conductor is the wrapped structure of juxtaposition formula, and outer conductor is provided with the quadrilateral hole that Rao Bao forms.
Said outer conductor comprises a clockwise twining package tape and a counterclockwise twining package tape, and twining package tape not exclusively covers fluid insulation clockwise, and forms continuous clockwise spiral helicine first clearance groove; Twining package tape not exclusively covers fluid insulation counterclockwise, and forms continuous counterclockwise spiral helicine second clearance groove; First clearance groove is intersected by counterclockwise twining package tape and covers, and second clearance groove is intersected by twining package tape clockwise and covers, and the zone that all is not capped at first clearance groove and second clearance groove forms quadrilateral hole.
The clockwise twining package tape of said outer conductor is that copper is moulded composite membrane or aluminum-plastic composite membrane, and its thickness is 0.05 millimeter to 0.10 millimeter.
The counterclockwise twining package tape of said outer conductor is that copper is moulded composite membrane or aluminum-plastic composite membrane, and its thickness is for being 0.05 millimeter to 0.10 millimeter.
Said quadrilateral hole is the aperture of period profile vertically.
Described quadrilateral hole is the wrapped formation of the double-deck juxtaposition of metal tape, and the left and right sides is asymmetric.
The invention has the beneficial effects as follows:
Cable outer conductor material of the present invention changes copper (aluminium) into and moulds composite membrane, has not only improved the pliability of material, has reduced outer conductor manufacturing process difficulty, has improved the production efficiency of leaky coaxial cable greatly; Can realize that also the outer conductor structure is more frivolous, save the metal material cost in a large number, improve the bending property of cable, have in light weight, softness good, bending radius is little, be easy to install and advantage such as lay.
Be mainly reflected in the following aspects:
⑴ alleviate outer conductor weight greatly, practices thrift cost.Outer conductor material of the present invention adopts copper (aluminium) to mould composite membrane, and it is original 1/4 that metal layer thickness is merely, the weight that therefore can practice thrift the outer conductor metal greatly.
⑵ line body is soft, and production efficiency is high.The present invention has bending property preferably owing to adopted the outer conductor of wrapped structure, and its minimum bending radius can reach 5 times of cable size; With respect to original embossing mode of grooving, its production efficiency is original 8 times.
⑶ mechanical performance is better.The present invention has better pliability, pull resistance, crushing resistance owing to adopted the outer conductor of double-deck wrapped structure, has improved the useful life of cable.
The present invention has changed the outer conductor manufacturing process of leaky coaxial cable outer conductor, adopts copper (aluminium) to mould the double-deck wrapped mode of composite membrane, has reduced the manufacturing process difficulty, has improved the production efficient of leaky coaxial cable; Through the wrapped mode of bilayer, the wrapped gap of outer conductor is stable, periodicity and high conformity, and can satisfy once wrapped coating operation, and can realize product approval, shortened the production cycle, improved production efficiency; Can mould the width and the lay of lapping of composite membrane outer conductor through adjustment copper (aluminium), come the size and the spacing in change pore size gap flexibly, thereby adapt to varying environment and frequency needs.
Below in conjunction with an optimization specific embodiment, invention is further understood in explanation of example property and help, but the embodiment detail only is for invention is described; Do not represent whole technical schemes under the inventive concept; Therefore should not be construed as inventing the qualification of total technical scheme, some do not depart from the unsubstantiality of inventive concept and change In the view of the technical staff; For example simple the change or replacement of technical characterictic to have same or similar technique effect all belongs to the invention protection range.
