Description
Technical field
The present invention relates to a kind of communication cable structure, particularly relate to the cable configuration being convenient in a kind of wire stripping process protect optical fiber.
Background technology
Light transmitting fiber, is called for short optical fiber, the light conduction instrument of the total reflection principle transmission in the fiber that to be a kind of light make at glass or plastics.Fine fibre-optic package, in plastic sheath, makes it to bend and is unlikely to fracture.The transmitter of one end of usual optical fiber uses light emitting diode or beam of laser that light pulse is sent to optical fiber, and the receiving equipment of the other end of optical fiber uses photosensitive components to detect pulse.The cable comprising optical fiber is called optical cable.Because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic transmission loss, more because main production raw material is silicon, reserves are very big, more easily exploit, so low price, impel optical fiber to be used as the media of information of long distance.Along with further optimization or the development in optic fibre manufacture process field and manufacturing equipment field, existing fiber price reduces further, and optical fiber improves rapidly at the total proportion of signal and communication cable.
Along with popularizing of optical-fibre communications, optical cable may be laid in various environment, and the structure optimizing optical cable further can ensure the serviceable life of optical cable undoubtedly or be convenient to laying of optical cable.
Summary of the invention
For above-mentioned popularizing along with optical-fibre communications; optical cable may be laid in various environment; the structure of further optimization optical cable can ensure the serviceable life of optical cable undoubtedly or be convenient to the problem of laying of optical cable, the invention provides the cable configuration being convenient in a kind of wire stripping process protect optical fiber.
For the problems referred to above, in wire stripping process provided by the invention, the cable configuration be convenient to optical fiber is protected solves problem by following technical essential: be convenient to the cable configuration protected optical fiber in wire stripping process, the fiber body comprising restrictive coating in a tubular form and be arranged in restrictive coating hollow space, also be provided with in described hollow space and tear rope, and described in tear rope contact with the internal face of restrictive coating, the internal face of described restrictive coating is also provided with stress breach, described stress breach is positioned at restrictive coating and tears on the contact point of rope, and described stress breach is bottom is the channel-shaped structure of wedge angle, the bottom land of this channel-shaped structure is parallel to the axis of restrictive coating, describedly tear rope and stress breach is multiple and both quantity are equal, and tear rope and stress breach one_to_one corresponding be distributed on the internal face of restrictive coating.
Concrete; what arrange tears the stripping of rope for this structure restrictive coating in wiring process; namely rope is torn by being pulled outwardly in the radial direction of restrictive coating; the extruding of tearing rope counter stress breach forces the bottom of stress breach to be torn; like this can less pull stress under on restrictive coating, form the complete tearing port running through outside in it; above less power of pullling can complete the less curable grip of restrictive coating simultaneously, therefore the present invention is not only beneficial to wire stripping efficiency, is also beneficial to protection fiber body.
Rope is torn in employing and stress breach is multiple and both quantity are equal, and tear rope and stress breach one_to_one corresponding is distributed on vibrational power flow on the internal face of restrictive coating, what be convenient to from restrictive coating is each to tearing restrictive coating simultaneously, being convenient to reduce fiber body by peeling off the resistance needing to overcome in the present invention, its stressed size in fiber body stripping process can be reduced further.
Further technical scheme is:
For protecting fiber body further, keeping the profile of packed layer, be also filled with packed layer in the hollow space of described restrictive coating, described fiber body is embedded in packed layer.
As the packed layer material that a kind of protective capacities is good, described packed layer is for filling fine cream.
As a kind of fiber body material of stable performance, described fiber body is tight tube fiber.
For making the present invention have good anti-electromagnetic field ability, described in tear rope for fiber rope.
For ease of improving ability to communicate of the present invention and being convenient to wiring of the present invention, more than one of described fiber body, and each fiber body is all coated with sign coating, the sign coating color on each fiber body is different.
The present invention has following beneficial effect:
1, in the present invention; what arrange tears the stripping of rope for this structure restrictive coating in wiring process; namely rope is torn by being pulled outwardly in the radial direction of restrictive coating; the extruding of tearing rope counter stress breach forces the bottom of stress breach to be torn; like this can less pull stress under on restrictive coating, form the complete tearing port running through outside in it; above less power of pullling can complete the less curable grip of restrictive coating simultaneously, therefore the present invention is not only beneficial to wire stripping efficiency, is also beneficial to protection fiber body.
2, adopt and tear rope and stress breach is multiple and both quantity are equal, and tear rope and stress breach one_to_one corresponding is distributed on vibrational power flow on the internal face of restrictive coating, what be convenient to from restrictive coating is each to tearing restrictive coating simultaneously, being convenient to reduce fiber body by peeling off the resistance needing to overcome in the present invention, its stressed size in fiber body stripping process can be reduced further.
Accompanying drawing explanation
