Abstract
The utility model discloses a multi-core coaxial cable, which comprises a plurality of single-core coaxial cables. A filling material layer is covered outside each coaxial cable. The single-core coaxial cables and the filling material layers are stranded into cable cores. A polycarbonate (PC) film layer is covered outside the cable cores. A first sheath is covered outside the PC film layer. Nylon yarns are arranged between the PC film layer and the first sheath. When the multi-core coaxial cable is peeled, a part of sheath can be exposed by drawing the nylon yarns. The multi-core coaxial cable is widely applicable, convenient to mount and maintain and easy to peel, and pipeline resources are saved.
Description
Technical field
The utility model relates to a kind of multicore coaxial cable.
Background technology
China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
Though wires and cables industry is a supporting industry just, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application very extensively; Relate to industries such as electric power, building, communication, manufacturing, all closely related with each department of national economy.Electric wire also is called as national economy " artery " and " nerve "; Be transmission of electric energy, transmission information and make various motors, instrument, instrument; Realizing the indispensable basic equipment of electromagnetic energy conversion, is necessary base product in following electrification, the informationized society.
Now coaxial cable comprises among the SYV and external several criteria of GB; All all stipulates by single coaxial cable; So when a plurality of communication units or a plurality of watch-dog; Pass piping erection after many coaxial electrical bindings must be arranged, so promptly increased other many work, also increased the cost that cable is installed.
The utility model content
In order to solve above technical problem, the utility model provides a kind of multicore coaxial cable.
The utility model discloses a kind of multicore coaxial cable, comprise many single core coaxial cables, the outside encapsulant layer that coats of each coaxial cable; Described single core coaxial cable and encapsulant layer are twisted into cable core; The outside PC rete that coats of described cable core, outside first sheath that coats of said PC rete is provided with nylon yarn between described PC rete and the sheath; During peeling, the described nylon yarn of tractive can make outside a sheath part is exposed to.
In the described multicore coaxial cable of the utility model, described single core coaxial cable comprises single copper wire, outside described copper wire, insulating barrier is set, and outside described insulating barrier, screen is set, and second sheath is set outside described screen.
In the described multicore coaxial cable of the utility model, described insulating barrier is low closely knit heart PE layer.
In the described multicore coaxial cable of the utility model, described screen is a tincopper fuse wire braided armor.
In the described multicore coaxial cable of the utility model, described tincopper fuse wire braided armor shielding rate >=90%.
Implement a kind of multicore coaxial cable of the utility model, have following beneficial technical effects:
Be widely used, multicore coaxial cable can make things convenient for installation and maintenance, and peeling is easy, has practiced thrift conduit resource.
Description of drawings
Fig. 1 is a kind of multicore coaxial cable structure of the utility model front view.
Embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.
See also Fig. 1, a kind of multicore coaxial cable comprises: single copper wire 1, insulating barrier 2, screen 3, second sheath 4, encapsulant layer 5, PC rete 6, nylon yarn 7, first sheath 8.
Comprise many single core coaxial cables in the cable; Be conductor with single copper wire 1 in the coaxial cable, the outside is an insulating barrier 2 with low closely knit heart PE, and insulating barrier 2 is outer to reach 90% above copper wire woven shield 3 with shielding rate again; Extrude second sheath 4 again outside the screen 3, promptly made single shaft cable.Add that with some single coaxial cable encapsulant layer 5 is stranded again, and coat one deck PC rete 6 outside the cable core after stranded and pack tightly cable core.Extrude first sheath 8 after the twisted cable core, when extruding first sheath 8, drag a nylon yarn 7, the effect of nylon yarn 7 is in installation process, in the peeling, can directly tear oversheath 8 with nylon yarn 7, makes things convenient for installation.
The purpose of the utility model is to restrain the deficiency in the used cable of newspaper; Extrude sheath to many single core coaxial cables again after stranded; And on the coaxial line of every single core, encode, make installation convenient, and need not increase extra installation procedure and cost.Simultaneously when oversheath is extruded, drag a nylon yarn, can make things convenient for peeling.
Implement a kind of multicore coaxial cable of the utility model, have following beneficial technical effects:
Be widely used, multicore coaxial cable can make things convenient for installation and maintenance, and peeling is easy, has practiced thrift conduit resource.
Combine accompanying drawing that the embodiment of the utility model is described above; But the utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection range of the utility model.
