Face is in flat, and the length value in the sheath section is 3 to 5 times of width value.
Further improvement of the present invention is as described below.
The two ends profile of the flat is respectively a semi arch, just to two halves circular arc between connected respectively by two parallel lines
Connect.
The radius of two halves circular arc is identical.
Including coated fiber, fine ointment, Loose tube, tight tube fiber and sheath；The Loose tube is sheathed on the coating light
Fibre, and the filling fine ointment in it；The coated fiber helically case of bending；The Loose tube, the tight tube fiber are equal
It is fixed on the inside of the sheath；The tight sleeve pipe of the tight tube fiber is identical with the material of the sheath.
The concentrically line of semi arch described in the tight tube fiber and one；The tight tube fiber and another semi arch are concentrically
Line.
In the central region of the sheath, flat cavity is set.

Embodiment
The present invention is further described for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of easily attach optical cable, including sheath 15；The section of the sheath 15 is in flat, the section of sheath 15
Length value is 3 to 5 times of width value.Sheath 15 is arranged to flat, and the length value in the section of sheath 15 is the 3 to 5 of width value
Times so that this, which easily attaches optical cable, can match the surface for being attached at circular pipe.
Specifically, the two ends profile of the flat is respectively a semi arch, just to two halves circular arc between by two straight parallels
Line is connected respectively, and the radius of two halves circular arc is identical.
The easy attaching optical cable of the present invention also includes coated fiber 11, fine ointment 12, Loose tube 13, tight tube fiber 14 and sheath
15；Loose tube 13 is sheathed on coated fiber 11, and the fine ointment 12 of filling in it；The helically case of bending of coated fiber 11；Pine set
Pipe 13, tight tube fiber 14 are both secured to the inside of sheath 15；The tight sleeve pipe 141 of tight tube fiber 14 is identical with the material of sheath 15.
By the semi arch of tight tube fiber 14 and one, concentrically line is set；By tight tube fiber 14 and another semi arch, concentrically line is set.So
Coated fiber 11 is used for temperature-compensating.When optical cable is by stress generation deformation, coated fiber 11, can not be strained due to length of having a surplus
Influence, it is only sensitive to temperature change.Then optical signal is gathered, is analyzed, i.e., accurately resolved temperature can be changed.Meanwhile, tightly
The tight sleeve pipe 141 of unjacketed optical fiber 14 is identical with the material of sheath 15, and when extruding sheath 15, sheath 15 can occur with tight sleeve pipe 141
Adhesion so that the structure of optical cable is compacted, unification degree high.When optical cable is by stress generation deformation, tight tube fiber 14 is long due to nothing left, energy
Enough not temperature influences, only to strain sensitive.Then optical signal is gathered, is analyzed, i.e., can accurately differentiate strain and become
Change.Therefore, this easily attach optical cable i.e. can resolved temperature change, can also differentiate strain variation.
Sheath 15 can also use identical hardness using the low material of low-smoke halogen-free flame-retardant sheath 15 of hardness, tight sleeve pipe 141
The low material of low-smoke halogen-free flame-retardant sheath 15, so as to provide advantage to being attached at tube circular surface, it is adaptable to colliery, oil well, stone
The strain abnormality monitoring system of oil-piping or natural gas line.
The present invention sets flat cavity 151 in the central region of sheath 15, and flat cavity 151 is in fusiform, flat cavity
151 length is the half of the cross-sectional length of sheath 15, so as to further improve on the attaching ability on tube circular surface, the flat
Cavity 151 can be formed by the mould straight forming of sheath 15.Strain transducer of the present invention includes aramid yarn 16, and aramid yarn 16 is worn
In in flat cavity 151, can ensureing that the tensile property of optical cable is excellent.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
