Abstract
A tensile optical cable comprises insulated metal leads, a sleeve and a sheath, wherein the sleeve and the sheath are sheathed outside the metal lead; the sheath is arranged on the outermost layer; ointment is filled between the sleeve and the metal lead; a plurality of wire ropes are arranged outside the sleeve; and a steel-plastic composite belt is arranged between the wire rope and the sheath. Compared with the prior art, the tensile optical cable has the advantages that as the ointment is filled between the sleeve and the metal lead, the metal lead can move freely; the friction between the sleeve and the metal lead is reduced; a plurality of wire ropes are arranged outside the sleeve and the steel-plastic composite belt is arranged between the wire rope and the sheath, thus increasing the tensile resistance. Therefore, the phenomena such as transmission failure, short circuit and the like can not occur due to rupture of the cable, and the service life is prolonged.
Description
Technical field
The utility model relates to optical-fibre communications field, particularly a kind of tension optical cable.
Background technology
At optical-fibre communications field, the structure of the cable line that uses mostly is at present, comprises the plain conductor of mutually insulated, and described plain conductor is wrapped with a sleeve pipe, and outermost layer is set to sheath.When this optical cable uses, be fine generally speaking.But in transportation, installation process, if the constructor is not careful and responsible, this optical cable will cause phenomenons such as its transmission disorder even short circuit because of undue stretching can cause fracture, not only can influence normal use, and might cause huge disaster and casualties.
The utility model content
Technical problem to be solved in the utility model is, at above-mentioned prior art present situation, and provides in a kind of transportation, the installation process the not tension optical cable of easy fracture.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of tension optical cable, comprise mutually insulated plain conductor, be placed in described plain conductor outer sleeve pipe and sheath, described sheath is arranged on outermost layer, it is characterized in that: being full of between described sleeve pipe and plain conductor has ointment; Be outside equipped with some steel wires at described sleeve pipe, be provided with a composite steel-plastic belt between described steel wire and the described sheath.
Described steel wire is 12.
Compared with prior art, advantage of the present utility model is, owing to be flooded with ointment between sleeve pipe and plain conductor, makes plain conductor to move freely, and has reduced friction each other; Be outside equipped with some steel wires at sleeve pipe, also be provided with a composite steel-plastic belt between steel wire and the sheath, increased pull resistance of the present utility model.Like this, the utility model fracture just can not occur and cause phenomenons such as transmission interruption, short circuit, has increased its serviceable life.
Description of drawings
Fig. 1 is the cross section structure synoptic diagram of the utility model embodiment.
Embodiment
According to embodiment and accompanying drawing the utility model is described in further detail below.
As shown in Figure 1, a kind of tension optical cable, comprise mutually insulated plain conductor 1, be placed in described plain conductor 1 outer sleeve pipe 3 and sheath 6, described sheath 6 is arranged on outermost layer, being full of between described sleeve pipe 3 and plain conductor 1 has ointment 2; Be outside equipped with 12 steel wires 4 at described sleeve pipe 3, be provided with a composite steel-plastic belt 5 between described steel wire 4 and the described sheath 6.
Claims (2)
1. tension optical cable, comprise mutually insulated plain conductor (1), be placed in described plain conductor (1) outer sleeve pipe (3) and sheath (6), described sheath (6) is arranged on outermost layer, it is characterized in that: being full of between described sleeve pipe (3) and plain conductor (1) has ointment (2); Be outside equipped with some steel wires (4) at described sleeve pipe (3), be provided with a composite steel-plastic belt (5) between described steel wire (4) and the described sheath (6).
2. tension optical cable according to claim 1 is characterized in that: described steel wire (4) is 12.
