The utility model discloses the special-shaped optical cable is a high-strength miniature optical cable, and trapezoidal scarce grooves are arranged on the positive and negative sides of the outer sheath, thus reducing the weight and facilitating the transportation, and moreover, because the trapezoidal scarce grooves can release the pressure during bending, the special-shaped optical cable also has the advantage of bending resistance; on the basis, a pair of tensile elements is arranged in the outer sheath, so that the pressure resistance of the special-shaped optical cable is enhanced.
Description
Technical field
A kind of optical cable is the utility model is related to, belongs to optical cable field.
Background technology
High strength micro optical fiber cable under water the field such as robot, fiber-optic guidance weapon apply when, to its intensity and tension
Property require that high performance.And existing this kind of micro optical cable typically selects the big material of density to ensure stiffening effect,
It is excessive to thereby result in meeting weight, not pliable, transport installation process is also inconvenient.
The content of the invention
The technical problem that the utility model need to solve be overcome the shortcomings of it is above-mentioned, there is provided a kind of bending resistance and measuring body different in nature light
Cable.
To solve above-mentioned technical problem, the utility model devises a kind of special-shaped optical cable, and it includes：Fiber cores, parcel
The aramid layers of fiber cores and the oversheath of cladding aramid layers, a diameter of 250 microns of the fiber cores, the oversheath is flat
Shape；Wherein, the positive/negative side of the oversheath is equipped with three trapezoidal short slots, and short slot is mutual on the positive/negative side of oversheath
Extend in parallel, a pair of tensile elements are additionally provided with the oversheath, the longitudinal cross-section of the pair of tensile elements is in semicircle
Shape, semicircle are open towards aramid layers.
Further improved as the utility model, the trapezoidal short slot interval is evenly distributed on just tossing about for the oversheath
On face.
Further improved as the utility model, the pair of tensile elements are located at two outboard ends of oversheath respectively.
Further improved as the utility model, the Central Symmetry of the pair of tensile elements opposed optical fibers core.
The utility model opposite sex optical cable is a kind of micro optical cable of high intensity, is equipped with the positive and negative both sides of oversheath trapezoidal
Short slot, can so mitigate weight, convenience in transport, also, pressure when can discharge due to trapezoidal short slot bending, thus, this reality
The advantages of bending resistance being also equipped with new different in nature optical cable；On this basis, a pair of tensile elements are provided with oversheath, make this practicality
The anti-pressure ability enhancing of new different in nature optical cable.
Brief description of the drawings
Exemplary embodiment of the present utility model is more fully described by referring to accompanying drawing, in the accompanying drawings：
Fig. 1 is a kind of longitudinal profile structure schematic of special-shaped optical cable of the present utility model.
Embodiment
Hereinafter, the utility model is more fully described now with reference to accompanying drawing, various implementations is shown in the drawings
Example.However, the utility model can be implemented in many different forms, and it should not be construed as limited to reality set forth herein
Apply example.On the contrary, it will be thorough and complete to these embodiments are provided so that the utility model discloses, and by model of the present utility model
Enclose and be fully conveyed to those skilled in the art.
Hereinafter, exemplary embodiment of the present utility model is more fully described with reference to the accompanying drawings.
Different in nature optical cable of the present utility model is a kind of ruggedized fiber optic cable, including：Fiber cores 1, aramid layers 2 and oversheath 3.Institute
State fiber cores a diameter of 250 microns, the oversheath are pancake.
Aramid layers 2 wrap up fiber cores 1, and aramid layers 3 have good tensile capacity.
Oversheath 3 coats the aramid layers 2, and oversheath 3 is big using density, and the material of high intensity is made, such as, high density
Copolymer resin.
Be equipped with three trapezoidal short slots 4 in the positive/negative side 30,31 of oversheath 3, trapezoidal short slot 4 oversheath 3 just/
Toss about and extend parallel to each other on face.Trapezoidal short slot is provided with the side of oversheath 3, can so mitigate weight, convenience in transport,
Moreover, pressure when trapezoidal short slot can also discharge bending, thus, the advantages of the utility model opposite sex optical cable is also equipped with bending resistance.
The utility model is additionally provided with a pair of tensile elements 5 in the oversheath 3, and tensile elements 5 are located at oversheath 3 respectively
Two outboard ends, and the Central Symmetry of opposed optical fibers core 1.The longitudinal cross-section semicircular in shape of tensile elements 5, semicircle opening court
To aramid layers, i.e. a pair of tensile elements 5 are located in oversheath 3 as a pair " () ".Tensile elements 5 can use quality light, have tough
The material of property is made, such as the rubber of low-density.Tensile elements 5 are located at two outboard ends of oversheath, and are half of opening inwardly
Circle, semicircle can bear pressure, can so increase the crushing resistance of different in nature optical cable, make the increase of its anti-pressure ability.
The utility model opposite sex optical cable is a kind of ruggedized fiber optic cable, and trapezoidal short slot is equipped with the positive/negative both sides of oversheath,
It can so mitigate weight, convenience in transport, also, pressure when can discharge due to trapezoidal short slot bending, thus, the utility model
The characteristics of different in nature optical cable is also equipped with bending resistance；On this basis, a pair of tensile elements are provided with oversheath, make the utility model different
Property optical cable anti-pressure ability enhancing.
Embodiment of the present utility model is the foregoing is only, is not limited to the utility model.The utility model
Can there are various suitable changes and change.All made within spirit of the present utility model and principle are any to be changed, is equivalent
Replace, improve etc., it should be included within the scope of protection of the utility model.
