Abstract
The invention relates to a novel optical cable resisting repeated bending. The novel optical cable comprises a cable core and an external sheath. The cable core is composed of multiple tight buffered optical fibers. An armored bellows coaxially sleeves the external part of the cable core. A reinforced protective layer coaxially sleeves the external part of the armored bellows. The external sheath coaxially sleeves the external part of the reinforced protective layer. The novel optical cable resisting repeated bending is ingenious in design, reasonable in structure and low in cost. According to the optical cable, the product structure is reasonably designed so that the optical cable is enabled have the property of bending resistance, maintenance cost is reduced, the special requirements of users can be met and the optical cable is suitable for elevators and other occasions.
Description
Technical field
The present invention relates to optical cable field, the Novel optical cable of a kind of resistance to alternating bending.
Background technology
Optical cable be manufacture to meet the performance specification of optics, machinery or environment in order to realize the logical of optical signal transmission
Letter circuit, it is to utilize one or more optical fiber being placed in cladding sheath as transmission medium and can individually or in groups use
Communications cable assembly, it may be assumed that the cable formed through certain technique by optical fiber (optical transmission carrier).At present, special at some
Different occasion, optical cable needs have certain pliability, it would be desirable to be able to alternating bending, such as elevator etc., and existing optical cable is the most not
Can meet demand, not reach the effect of alternating bending, therefore service life is shorter, needs often to change, thus adds user
Cost, it is impossible to reach the requirement of user.
Summary of the invention
In place of it is an object of the invention to make up the deficiencies in the prior art, it is provided that a kind of pliability is good, service life length
The Novel optical cable of resistance to alternating bending.
It is an object of the invention to be realized by techniques below means:
The Novel optical cable of a kind of resistance to alternating bending, including cable core and oversheath, it is characterised in that: described cable core is by many
Tight tube fiber forms, and the outer, coaxial at cable core is set with an armouring corrugated tube, and the outer, coaxial at this armouring corrugated tube is set with
Strengthening overcoat for one, the outer, coaxial at this reinforcement overcoat is set with oversheath.
And, described tight tube fiber includes optical fiber and tight sleeve layer, and this tight sleeve layer is wrapped in outer fiber.
And, described reinforcement overcoat is aramid layers.
Advantages of the present invention and good effect be:
1, this optical cable is provided with armouring corrugated tube and aramid layers in optical cable, and this design not only can alleviate the weight of optical cable
Amount, also has pliability, makes optical cable with alternating bending, can extend the service life of optical cable, and therefore this optical cable is applicable to
The occasion of alternating bending.
2, due to this optical cable resist bending, it is hardly damaged, later maintenance and the number of times of replacing and expense after using, can be reduced
With, therefore can meet user's request.
3, the present invention is the Novel optical cable of a kind of resistance to alternating bending designing ingenious, rational in infrastructure, low cost, and this optical cable leads to
Cross the appropriate design to product structure so that it is be provided with resistant to bending characteristic, decrease maintenance cost, meet the special of user
Demand, is suitable for use in the occasions such as elevator.
Accompanying drawing explanation
Fig. 1 is the cross sectional view of the present invention.
Detailed description of the invention
Describe embodiments of the invention the most in detail；It should be noted that the present embodiment is narrative, no
It is determinate, it is impossible to limit protection scope of the present invention with this.
The Novel optical cable of a kind of resistance to alternating bending, including cable core 4, armouring corrugated tube 3, strengthens overcoat 2 and oversheath 1,
Described cable core is made up of many tight tube fibers, and described tight tube fiber includes optical fiber 5 and tight sleeve layer 6, this tight sleeve layer bag
It is rolled in outer fiber.
Outer, coaxial at cable core is set with an armouring corrugated tube, and the outer, coaxial at this armouring corrugated tube is set with one and adds
Strong overcoat, this reinforcement overcoat is aramid layers, and the outer, coaxial in aramid layers is set with oversheath.
The operation principle of the present invention is:
The present invention is provided with armouring corrugated tube and aramid layers in optical cable, utilizes its construction features, can reach repeatedly
The purpose of bending.
Claims (3)
1. a Novel optical cable for resistance to alternating bending, including cable core and oversheath, it is characterised in that: described cable core is tight by many
