Abstract

The utility model discloses an armored rubber-insulated optical cable which comprises a cable core unit, wherein the cable core unit comprises an optical fiber unit located in the center, and an inner reinforced part and an inner protective sleeve which are located at both sides of the optical fiber unit; edges of both sides of the inner protective sleeve are provided with tearing openings corresponding to the optical fiber unit; both sides of the cable core unit are provided with cable release wires corresponding to the tearing openings; and a waterproofing belt, an aluminum-plastic composite belt and an outer protective sleeve are sequentially arranged outside the cable core unit and the cable release wires from inside to outside. By adding the waterproofing belt, the aluminum-plastic composite belt and the outer protective sleeve outside the cable core unit, the utility model ensures that the optical fibers can be well protected during the construction of indoor cables in a pipeline, and reduces the negative effects caused by the construction; and the transmission performance can not be affected even if the environmental conditions are poor.

Description

The armouring covered wire cable

Technical field

the utility model relates to a kind of armouring covered wire cable.

Background technology

in recent years, the optical fiber access market of China demonstrates good growth momentum, optical fiber inserts has become the focus in the optical communication field.In optical fiber inserts engineering, be complex link the most near user's house wiring.Because traditional outdoor optical cable external diameter is big, hardness is big, contains ointment usually, and is not fire-retardant, and these characteristics cause outdoor optical cable not to be suitable in the building.Traditional inside cable then have do not block water, deficiency that anti-ultraviolet aging, intensity do not satisfy aspects such as outdoor optical cable request for utilization, should not be applicable to also outside the building that drawing in the building connects.To such situation, outdoor optical cable is registered one's residence a fiber cable cross connection box normally is set in the building, carries out the switching of optical cable.But for the lower loose type user of density, this processing mode has increased construction and maintenance cost, is not optimal solution.Existing covered wire cable is not suitable for the construction of poling road, because the LSZH that covered wire cable uses material surface is softer, not wear-resistant, construction causes the external force damage easily in pipeline.

Summary of the invention

are for solving existing optical cable frangible, phenomenon such as non-watertight, not fire-retardant, not wear-resistant; The utility model purpose provides a kind of armouring covered wire cable; It has increased waterstop, aluminium-plastic tape and oversheath outside the cable core unit; Therefore the intensity of optical cable is bigger, stronger to the protection of optical fiber, system of laying is more, is applicable to architecture pipe or the built on stilts cable of introducing.

The technical scheme of the utility model is: a kind of armouring covered wire cable; Comprise the cable core unit; The cable core unit is made up of the fiber unit that is positioned at the center, the reinforcement that is positioned at the fiber unit both sides and inner sheath; The both sides of the edge of inner sheath and fiber unit corresponding section are provided with tearing port; The both sides of said cable core unit also are provided with out hawser corresponding to the position of tearing port, are positioned at the cable core unit and are provided with waterstop, aluminium-plastic tape and oversheath outside the hawser from inside to outside successively with opening.

are further, and said fiber unit is made up of one to four painted coated fiber.

The utility model has the advantages that:

Cable core unit in 1, the utility model is a covered wire cable; Covered wire cable is former to be not suitable for the construction of poling road, because the LSZH that covered wire cable uses material surface is softer, not wear-resistant; Construction causes the external force damage easily in pipeline; So the utility model increased waterstop, aluminium-plastic tape and oversheath outside the cable core unit, guarantee that indoor cable construct also can well protect optical fiber in pipeline, lower the negative effect of constructing and bringing; Even environmental baseline is bad, can not influence its transmission performance.

even, the utility model uses the aluminum plastic composite belt longitudinal bag to add waterstop when the heavier environment of moisture uses, also can better protect optical fiber, block water, moisture effect is good.

, the utlity model has certain anti-rodent and bait ability.

Soft, flexible, the convenience that continues of , the utility model, and can support the Large Volume Data transmission.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the structural representation of the utility model.

Wherein:

1 cable core unit; 11 fiber units; Reinforcement in 12; 13 inner sheaths; 14 tearing ports;

2 open hawser;

3 waterstops;

4 aluminium-plastic tapes;

5 oversheaths.

Embodiment

embodiment: as shown in Figure 1; A kind of armouring covered wire cable; Comprise cable core unit 1; Cable core unit 1 is made up of the fiber unit that is positioned at the center 11, the reinforcement 12 that is positioned at fiber unit 11 both sides and inner sheath 13; The both sides of the edge of inner sheath 13 and fiber unit 11 corresponding sections are provided with tearing port 14, and the both sides of said cable core unit 1 also are provided with out hawser 2 corresponding to the position of tearing port 14, are positioned at cable core unit 1 and are provided with waterstop 3, aluminium-plastic tape 4 and oversheath 5 outside the hawser 2 from inside to outside successively with opening.

said fiber unit 11 is made up of one to four painted coated fiber.The color of painted coated fiber can also can be and decide through consultation color according to the color dyes of standard code.

The material of said inner sheath 13 can be flame-proof polyvinyl chloride (PVC), low smoke halogen-free flame-retardant polyolefin (LSZH), polyurethane (TPU) or tygon (PE) or the like.

Cable core unit 1 in the utility model is traditional covered wire cable; Covered wire cable is former to be not suitable for the construction of poling road, because the LSZH that covered wire cable uses material surface is softer, not wear-resistant; Construction causes the external force damage easily in pipeline; So the utility model increased waterstop 3, aluminium-plastic tape 4 and oversheath 5 cable core unit 1 outside, guarantee that indoor cable construct also can well protect optical fiber, the negative effect that attenuating is constructed and brought in pipeline; Even environmental baseline is bad, can not influence its transmission performance.

Only be the concrete exemplary applications of the utility model more than , the protection domain of the utility model is not constituted any limitation.Except that the foregoing description, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
