Description
Technical field
The utility model relates to communication wire rod field, relates to a kind of submarine coaxial telecommunication cable specifically.
Background technology
Communication cable is of a great variety, generally can classify by design feature, frequency of utilization, insulating forms, system of laying and sheath form.From structure point, there are symmetrical cable and the large class of coaxial cable two.The former, two heart yearns forming electric loop are symmetrical over the ground; Latter forms electric loop by two metallic conductors be nested with one heart.
Submarine communication cable is used for realizing between land and island, island and intercontinental transoceanic wire communication.It forms the world wide communication net in the present age together with satellite communication.Submarine communication cable has coaxial and symmetrical two kinds of structures, and the former is for long distance higher capacity link, and the latter is contrary.Submarine cable easily suffers that the impact of tide fluctuation and naval vessel cast anchor, the damage of fishing activity.At present, there is the not strong weakness of resistance to compression, anti-wear performance in submarine communication cable, and be subject to external force infringement, cable signal is subject to electromagnetic interference.Therefore, traditional submarine communication cable structure needs to improve.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of submarine coaxial telecommunication cable, and this cable resistance to compression, abrasive resistance are strong.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of submarine coaxial telecommunication cable, the outermost layer of this telecommunication cable is the serving that anticorrosion material is made, inside by serving, the netted braid be made up of copper material successively, tegillum in making with the identical material of serving, armouring wire layer, PVC laying, sheath, outer conductor layer, insulating barrier, inner conductor layer, the inwall of described interior tegillum is provided with jagged quil region, described armouring wire layer is coated on the outer surface of PVC laying, the gap into armouring wire layer is stung by the tip in the quil region on the inwall of interior tegillum, armouring wire layer is fixed.
Further, the quil in described quil region arranges 5 ~ 10 circles in the longitudinal direction of pipe.
Further, described interior tegillum arranges a circle quil region every 50cm distance.
Further, described PVC laying is provided with two-layer.
Further, two-layer PVC laying thickness is identical.
Further, netted braid is diamond weave structure.
Relative to prior art, the beneficial effects of the utility model are: the outermost layer of the utility model telecommunication cable is the serving that anticorrosion material is made, inside by serving, the netted braid be made up of copper material successively, tegillum in making with the identical material of serving, armouring wire layer, PVC laying, sheath, outer conductor layer, insulating barrier, inner conductor layer, the inwall of described interior tegillum is provided with jagged quil region, described armouring wire layer is coated on the outer surface of PVC laying, the gap into armouring wire layer is stung by the tip in the quil region on the inwall of interior tegillum, armouring wire layer is fixed.The netted braid that copper material is made has the function of electromagnetism interference, makes the signal of communication of cable more stable.Because armouring wire layer is tied up by some round wires to form, easily be moved under being subject to the effect of external force, make outside serving stressed larger, easy fracture, therefore, interior tegillum inwall is provided with quil region, the tip of quil can be made to prick on the gap between steel wire and steel wire, even if also not easily move under making whole armouring wire layer be subject to the effect of external force, firm in structure.

Mark in accompanying drawing: serving 1, netted braid 2, interior tegillum 3, armouring wire layer 4, PVC laying 5, sheath 6, outer conductor layer 7, insulating barrier 8, inner conductor layer 9, quil region 31.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 1 ~ 3, a kind of submarine coaxial telecommunication cable of the present utility model, the outermost layer of this telecommunication cable is the serving 1 that anticorrosion material is made, inside by serving 1, the netted braid 2 be made up of copper material successively, tegillum 3 in making with the identical material of serving 1, armouring wire layer 4, PVC laying 5, sheath 6, outer conductor layer 7, insulating barrier 8, inner conductor layer 9, the inwall of described interior tegillum 3 is provided with jagged quil region 31, described armouring wire layer 4 is coated on the outer surface of PVC laying 5, the gap into armouring wire layer 4 is stung by the tip in the quil region 31 on the inwall of interior tegillum 3, armouring wire layer 4 is fixed.Described interior tegillum 3 arranges a circle quil region 31 every 50cm distance, and described PVC laying 5 is provided with two-layer, and two-layer PVC laying 5 thickness is identical.
Netted braid 2 is diamond weave structure, and netted braid 2 is copper material, has good electromagnetism interference, makes the signal of communication of cable more stable.
Because submarine cable is cast anchor by the impact of tide fluctuation and naval vessel easily, the damage of fishing activity, heavy weight steel wire armouring should be had to protect, therefore, armouring wire layer 4 is provided with at interior tegillum 3, armouring wire layer 4 is tied up by some round wires to form, easily be moved under being subject to the effect of external force, make outside serving stressed larger, easy fracture, therefore, interior tegillum inwall is provided with quil region, the tip of quil can be made to prick on the gap between steel wire and steel wire, even if also not easily move under making whole armouring wire layer be subject to the effect of external force, firm in structure.
As shown in Figure 3, quil region 31 does not need all to arrange at whole interior tegillum 3, and only need arrange 5 ~ 10 circles in the longitudinal direction of interior tegillum 3 pipe, arranges a circle quil region 31, can save technology difficulty like this, can reduce production cost yet every 50cm distance.
The foregoing is only preferred implementation of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
