Abstract
The invention discloses a two-core waterproof optical cable. The two-core waterproof optical cable comprises a metal armoring tube; the metal armoring tube is sleeved with a PE outer protective tube; two single-core optical cables and two filling tubes are arranged in the metal armoring tube; and the two single-core optical cables and the two filling tubes are arranged in a two-line two-column array manner; and the two single-core optical cables are located at the same line or the same column.
Description
Technical field
The present invention relates to cable configuration, specifically two core waterproof cables.
Background technology
Optical cable is a kind of light conduction instrument reaching the total reflection principle transmission caused in fiber that light makes at glass or plastics.Optical cable is that the optical fiber of some forms the cable heart according to certain way, is surrounded by sheath outward, the also coated outer jacket had, in order to realize a kind of communication line of optical signal transmission.In prior art; the structure of optical cable comprises inner optical fiber module, outside protective layer structure; optical fiber module carries out circumference array by multiple optical fiber to be formed; there is no fill material between optical fiber simultaneously; therefore this kind of optical cable is when bending turning to, and makes arbitrarily inner optical fiber extrude mutually, very large to the harm of optical fiber; this type optical fiber easily causes optical cable to rotate around own axes in long transmission line process of deployment simultaneously, can increase the weight of the mutual extruding between optical fiber like this.
Summary of the invention
The object of the present invention is to provide a kind of two core waterproof cables, optical cable can not be rotated around own axes in long distance process of deployment, extrude mutually between the optical fiber that can not be.
Object of the present invention is achieved through the following technical solutions: two core waterproof cables, comprise metal armouring pipe, the outer pillar of PE is arranged with outside metal armouring pipe, 2 single fiber cables and 2 filling tubes are provided with in metal armouring pipe, 2 single fiber cables and 2 filling tubes carry out array arrangement according to two row two row, and 2 single fiber cables are in same a line or same row.
Design concept of the present invention is: the single fiber cable single fiber cable that traditional circular array is formed being changed into line-column matrix arrangement, the single fiber cable of tradition circular array, because its shape is circular, time bending, all consistent at any stressing conditions in the radial direction, and in the present invention, adopt the single fiber cable of rectanglar arrangement, the vertical direction on the long limit of the single fiber cable group only after array structure stressed less, effectively can guide the steering direction of optical cable, and turning to of the single fiber cable of traditional circular array is arbitrary, therefore it easily causes optical cable to rotate around own axes, and optical cable of the present invention, because the single fiber cable of inner rectangular array and 2 filling tubes form a rectangular array module, therefore can ensure that the bending direction of optical cable is directed, optical cable is not easily caused to rotate around own axes, the bending direction of optical cable carries out bending around the centerline line of 2 single fiber cables.
The present invention simultaneously adopts filling member to be filled between the adjacent fiber gap of optical fiber module, ensures certain isolation characteristic, prevents the transition between optical fiber from extruding impaired.Be provided with filling member in metal armouring pipe, 2 single fiber cables and 2 filling tubes embed filling member inside.
Preferably, 2 single fiber cables abut against mutually together, and 2 filling tubes are together adjacent to each other.
Preferably, the center of metal armouring pipe is provided with rubber center reinforcing prop.
Preferably, gasket for packing is filled with in filling tube.
The invention has the advantages that: reach protection optical fiber, optical cable can not be rotated around own axes in long distance process of deployment, extrude mutually between the optical fiber that can not be.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Reference numeral in figure is expressed as: 1, the outer pillar of PE; 2, metal armouring pipe; 3, single fiber cable; 4, filling tube; 5, rubber center reinforcing prop.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment 1:
As shown in Figure 1.
Two core waterproof cables, comprise metal armouring pipe 2, the outer pillar 1 of PE is arranged with outside metal armouring pipe 2,2 single fiber cables 3 and 2 filling tubes 4 are provided with in metal armouring pipe 2,2 single fiber cables 3 and 2 filling tubes 4 carry out array arrangement according to two row two row, and 2 single fiber cables 3 are in same a line or same row.
Design concept of the present invention is: the single fiber cable single fiber cable that traditional circular array is formed being changed into line-column matrix arrangement, the single fiber cable of tradition circular array, because its shape is circular, time bending, all consistent at any stressing conditions in the radial direction, and in the present invention, adopt the single fiber cable of rectanglar arrangement, the vertical direction on the long limit of the single fiber cable group only after array structure stressed less, effectively can guide the steering direction of optical cable, and turning to of the single fiber cable of traditional circular array is arbitrary, therefore it easily causes optical cable to rotate around own axes, and optical cable of the present invention, because the single fiber cable of inner rectangular array and 2 filling tubes 4 form a rectangular array module, therefore can ensure that the bending direction of optical cable is directed, optical cable is not easily caused to rotate around own axes.
The present invention simultaneously adopts filling member to be filled between the adjacent fiber gap of optical fiber module, ensures certain isolation characteristic, prevents the transition between optical fiber from extruding impaired.Be provided with filling member in metal armouring pipe 2,2 single fiber cables 3 and 2 filling tubes 4 embed filling member inside.
Preferably, 2 single fiber cables 3 abut against mutually together, and 2 filling tubes 4 are together adjacent to each other.
Preferably, the center of metal armouring pipe 2 is provided with rubber center reinforcing prop 5.
Preferably, gasket for packing is filled with in filling tube.
As mentioned above, then well the present invention can be realized.
