Description
Technical field
The utility model relates to technical field of cables, particularly a kind of skeleton cable.
Background technology
Along with the continuous development of electric power, telecommunications industry, various cables are widely used in every field, and therefore, line cable industry also becomes each national basic activity gradually.Existing cable is normally inserted the insulated wire cores of power transmission line or holding wire, telephone wire in the protective layer, when needs use, with the strip off of whole protecting layer, thereby realizes the connection of electric wire.Therefore, when the long cable of a length is repeatedly inserted, can produce a plurality of joints, and each joint all having increased the loss of circuit virtually, and, usually can break down in the joint; In addition, adopt the bag that continues to install, brought extra expenditure to the user in each joint, therefore very uneconomical.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of skeleton cable to be provided, and it is realized by the following technical solutions:
Skeleton cable, it includes at least one group of cable core 5, it is characterized in that: it also comprises a skeleton 1, a protective layer 3 and an outer jacket 4 at least; Have two skeleton grooves 11 on the described skeleton at least, protective layer 3 is positioned at outside the skeleton, and outer jacket 4 is positioned at outside the protective layer; Described cable core 5 is positioned at skeleton grooves 11.
Above-mentioned described skeleton inside also can be provided with reinforcement 2, and described reinforcement is metal or nonmetallic.
Above-mentioned described skeleton grooves is positioned at the periphery of skeleton, is evenly or uneven distribution.
The preferential crescent of the cross-sectional profile of above-mentioned described skeleton grooves, trapezoidal or rectangle.
Above-mentioned described skeleton grooves along skeleton axial be distributed as spiral.
Above-mentioned described skeleton grooves along skeleton axial be distributed as one section up time pin type, one section inverse time pin type, and be gap distribution.
Above-mentioned described skeleton grooves is 20mm ~ 1000mm along the axial pitch of skeleton.
The material of above-mentioned described skeleton is plastics, preferably polyethylene, polypropylene, polyvinyl chloride, low smoke and zero halogen polyethylene.
The preferred waterstop of above-mentioned described protective layer, polyester belt, nonwoven fabrics.
Above-mentioned described protective layer overlays on outside the skeleton along the axis vertical coating or the spiral layers stacked package of skeleton.
Above-mentioned described protective layer material is plastics, preferably polyethylene, polyvinyl chloride, low smoke and zero halogen polyethylene.
Above-mentioned described cable core is any one or the two or more combination arbitrarily in signal cable, fire prevention, fire-resistant, fire-retardant, the power cable core.
Above-mentioned described cable core also can be and does not coat plastic sheathed sub-thread or multiply bare metal wire bundle or be coated with tin or the wire bundle of zinc.
Because cable core, therefore, when continuing, only needs axially to scratch protective coverings of cable and protective layer along skeleton along the skeleton axial distribution in skeleton grooves, can take out the cable core that will continue, and can not influence the cable core that other need not continue; Therefore, reduce the joint quantity of whole cable effectively, reduced the loss that continues effectively, saved the time of continuing, increased the reliability of system; And, because therefore the place of only continuing and need continue, does not need to set up in addition to continue and wrap or splice tray, only need to adopt cheap heat-shrinkable T bush, therefore, reduced unnecessary expenditure, saved expense, and made maintenance more convenient.

Embodiment
Embodiment one:
Ask for an interview Fig. 1, Fig. 2 and Fig. 3, skeleton cable, it includes cable core, it is characterized in that: it also comprises a skeleton 1, a protective layer 3 and an outer jacket 4; Eight skeleton grooves 11 on the described skeleton, protective layer 3 is positioned at outside the skeleton, and outer jacket 4 is positioned at outside the protective layer; Described cable core is positioned at skeleton grooves 11; skeleton inside also is provided with metal reinforcement 2; skeleton grooves is positioned at the periphery of skeleton; be evenly distributed; the cross-sectional profile of skeleton grooves is a crescent; skeleton grooves along skeleton axial be distributed as spiral; above-mentioned described skeleton grooves is 200mm along the axial pitch of skeleton; the material of skeleton is a vinyon; protective layer is a nonwoven fabrics; protective layer is coated on outside the skeleton along the axis vertical of skeleton, and protective layer material is the low smoke and zero halogen vinyon, and cable core is a signal cable.
Embodiment two:
Ask for an interview Fig. 4 and Fig. 5, with embodiment one, difference is skeleton substantially, four skeleton grooves 11 on the described skeleton.
Embodiment three:
Ask for an interview Fig. 6, skeleton cable, it includes five groups of cable cores 5, it is characterized in that: it also comprises a skeleton 1, a protective layer 3 and an outer jacket 4; Five skeleton grooves 11 on the described skeleton, protective layer 3 is positioned at outside the skeleton, and outer jacket 4 is positioned at outside the protective layer; Described cable core 5 is positioned at skeleton grooves 11; skeleton inside also is provided with metal reinforcement 2; skeleton grooves is positioned at the periphery of skeleton; be evenly distributed; the cross-sectional profile of skeleton grooves is trapezoidal; skeleton grooves along skeleton axial be distributed as spiral; above-mentioned described skeleton grooves is 500mm along the axial pitch of skeleton; the material of skeleton is a vinyon, and protective layer is a nonwoven fabrics, and protective layer is coated on outside the skeleton along the axis vertical of skeleton; protective layer material is the low smoke and zero halogen vinyon; cable core is a signal cable, also is provided with to tear parts 6 in outer jacket, and its material is that aramid fiber is torn rope.
