Description
Technical field
The invention belongs to the communication field technical field, relate to data communication line, especially relate to a kind of armored self-supporting data cable.
Background technology
Data communication line is widely used in communication technique field, and communication has significant effects to its performance to data.Existing cable comprises pulling force, extruding force, puncture force etc. laying, usually being subjected to various mechanical external force effects in the process such as use.Because the effect of these external force, cable are in use, the easiest being damaged causes stopping production, the person, equipment or bigger accident to take place, and therefore needs metal material to protect cable as armour.Armouring mode commonly used comprises steel-tape armouring, wire armoring etc., but steel-tape armouring can only bear the extruding force effect, can not bear big pulling force, and wire armoring can only bear pulling force, can not bear extruding force.But in a lot of use occasions, need bear various mechanical external forces simultaneously, these armouring modes all can not satisfy instructions for use.
In order to improve the performance of cable, people have carried out long-term exploration.Chinese patent literature discloses a kind of armored data cable [application number: 200710166609.6], comprise cable core and PVC sheath, it is characterized in that, outside every cable core, be provided with insulating barrier, the PVC sheath is located at outside the cable core that has insulating barrier, outside the PVC sheath, laterally be wound with the armouring stainless steel band, outside the armouring stainless steel band, be provided with the screen of layer of copper silk or braided steel wire, outside the screen of copper wire or braided steel wire, be provided with external sheath layer.In addition, the somebody has invented a kind of armoured cable [application number: 200820039913.4], and it comprises the crowded stranding insulated wire cores that sheath is arranged, the outer stranded armour that has of core, armour is extruded with sheath outward again, and armour wherein is to mesh into an integral body by the type single line to constitute.Described type single line cross section can for Z type, watt shape, arc, fan-shaped or other can make steel wire mesh into all kinds of molded lines of an integral body.
Such scheme has improved cable performance to a certain extent, but the processing technology more complicated, and the production cycle is long, the processing cost height.In addition, lack functions such as waterproof, load-bearing, uvioresistant, be difficult to be applicable to complicated wild environment.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of reasonable in design, simple in structure, the mechanical strength height can bear various external force such as pulling force, extruding force and puncture force, and has the armored self-supporting data cable of waterproof, anti-ultraviolet property.
For achieving the above object, the present invention has adopted following technical proposal: this armored self-supporting data cable, comprise four groups of twisted-pair feeders and the inner sheath that is arranged on four groups of twisted-pair feeder peripheries, be provided with oversheath in the inner sheath periphery, it is characterized in that, every group of described twisted-pair feeder periphery is respectively equipped with the metal armouring layer, is filled with cable cream in inner sheath, is provided with the metal load-bearing line of longitudinal extension between described oversheath and the inner sheath.
Because every group of twisted-pair feeder all is provided with the metal armouring layer, so the structural strength height, avoid external force to invade.Owing to be provided with metal load-bearing line, therefore can effectively promote load-bearing property, adapt to the field and set up.Owing to be filled with cable cream, therefore have good waterproof and dampproof performance, and can reduce temperature interference, be convenient to the data stabilization transmission.Owing to be provided with oversheath and inner sheath, can effectively avoid ultraviolet ray and radiation.
In above-mentioned armored self-supporting data cable, be provided with its cross section in the described inner sheath and be criss-cross data line framework, this data line framework is divided into four zones that are used to place twisted-pair feeder with inner sheath, is respectively equipped with one group of above-mentioned twisted-pair feeder in each zone.
In above-mentioned armored self-supporting data cable, described metal load-bearing line has two and be arranged on the both sides of inner sheath symmetrically.
In above-mentioned armored self-supporting data cable, described metal armouring layer is wound in the twisted-pair feeder periphery by steel band and forms.
In above-mentioned armored self-supporting data cable, described inner sheath is made by the PVC material.
In above-mentioned armored self-supporting data cable, described oversheath is made by the PE material.
In above-mentioned armored self-supporting data cable, described metal load-bearing line is made by the phosphatization steel.
In above-mentioned armored self-supporting data cable, described data line framework is made of plastics.
In above-mentioned armored self-supporting data cable, described data line framework has four and is the spacer that cross is provided with, and is respectively equipped with the location barb in the outer end of every spacer.The location barb can prevent to occur in process of production dislocation and distortion, increases substantially product percent of pass, makes transfer of data more steady, quick, plays better resisting interference and the effect that prevents cross-talk.
Compared with prior art, the advantage of this armored self-supporting data cable is: 1, reasonable in design, simple in structure, the mechanical strength height can effectively prevent the external force invasion, and have the self-supporting effect, is suitable for the field and sets up use.2, the inside and outside dual sheath can effectively be avoided ultraviolet ray and radiation effect, and the cable cream of filling has the effect of waterproof, protection against the tide and reduction temperature interference.3, signal transmission performance is reliable and stable, and simple installation is easy to safeguard and check.4, be easy to processing and manufacturing, production cost is lower.
