Abstract
The invention discloses a filled type compression-resistant optical cable. The filled type compression-resistant optical cable comprises an outer sheath and multiple optical fiber units, the multiple optical fiber units are arranged in the outer sheath, a middle filling body is concentrically arranged in the outer sheath, a through hole is formed in the middle of the middle filling body, multiple support blocks which correspond to the optical fiber units respectively are arranged outside the middle filling body, the tail end of each support block is provided with an arc-shaped groove corresponding to the outer circle of the corresponding optical fiber unit, and a binding layer is arranged between the multiple optical fiber units and the outer sheath. By means of the mode of the filled type compression-resistant optical cable, fixation of the multiple optical fiber units is enhanced through cooperation between the middle filling body and the binding layer, when the outer sheath is compressed, the corresponding optical fiber unit and the support block are stressed, and the corresponding support block is shrunk inward elastically, so that the pressure and damage of the corresponding optical fiber unit is reduced, and use stability of the optical cable is enhanced.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of filled type anti-extrusion optical cable, comprise: external jacket and several fiber unit, described several fiber unit is separately positioned in external jacket, obturator in the middle of being provided with one heart one in described external jacket, in the middle of described, the middle part of obturator is provided with a through hole, in the middle of described, the outer setting of obturator has several back-up blocks corresponding with fiber unit respectively, the end of described back-up block is provided with the arc groove corresponding with fiber unit cylindrical, between described several fiber unit and external jacket, be provided with binding layer.
In a preferred embodiment of the present invention, in the middle of described several fiber unit annular arrays are arranged on, obturator around.
In a preferred embodiment of the present invention, the pre-buried reinforcement core body that is provided with in described external jacket, described reinforcement core body is steel wire or Fiber glass rod.
In a preferred embodiment of the present invention, described external jacket is high density polyethylene (HDPE) sheath.
In a preferred embodiment of the present invention, described middle obturator is elastic caoutchouc obturator.
The invention has the beneficial effects as follows: the anti-extrusion optical cable of a kind of filled type that the present invention points out, the cooperation of obturator and binding layer in the middle of utilizing, strengthen the fixing of several fiber units, when external jacket is extruded, corresponding fiber unit and back-up block are stressed, the inside elastic shrinkage of back-up block and reduced pressure and the damage of fiber unit, has promoted the stability in use of optical cable.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation of anti-extrusion optical cable one preferred embodiment of a kind of filled type of the present invention.
Detailed description of the invention
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
