Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Embodiment
A kind of fixed type leading in cable of easy stripping multicore referring to Fig.1, including several optical fiber bodies 1 and is set in outside optical fiber body 1
The tight sleeve layer 3 in portion.In order to reduce resistance when stripping fiber optic cables, there are certain gaps between optical fiber body 1 and tight sleeve layer 3.This reality
The size for precomputing the tight sleeve layer 3 being set in outside optical fiber body 1 in example by the size of optical fiber body 1 is applied, it is raw in tight sleeve layer 3
By adjusting mold when production, the poly- fine needle of installation in the point of incoming cables of head plays the work gathered to optical fiber body 1 using poly- fine needle tubing
With by the proportion of tubular molding tool, the mold core for the use of diameter being 0.8mm, diameter is the die sleeve of 1.6mm, and that produces is fixed
There are certain gaps between layer 3 and optical fiber body 1 to be easily peeled off.
Referring to Fig.1, the inside of tight sleeve layer 3 is also equipped with several tear ropes 4, and whole tear ropes 4 is interior with tight sleeve layer 3
Side wall contact.The stress breach 32 cooperated with tear rope 4 is provided with simultaneously for the ease of the use of tear rope 4, on tight sleeve layer 3,
At the position that tear rope 4 is arranged in stress breach 32 and tight sleeve layer 3 contacts.The rank street face axial along tight sleeve layer 3 of stress breach 32
The opening of V-shaped setting, stress breach 32 is arranged towards tear rope 4.Tear rope 4 is symmetrically arranged with two groups in the present embodiment, and
Tear rope 4 and stress breach 32 are arranged in an axially parallel mode with tight sleeve layer 3.
Referring to Fig.1, the outer wall of tight sleeve layer 3 is arranged with the non-metal reinforced layer 5 being bonded with it, it is nonmetallic in the present embodiment plus
The preferred aramid yarn of material of strong layer 5.
Referring to Figures 1 and 2, the outer wall of non-metal reinforced layer 5 is successively arranged with enhancement layer 6 and fire-retardant set 7, is arranged in non-gold
Belong to the preferred composite steel-plastic belt of enhancement layer 6 between enhancement layer 5 and fire-retardant set 7.It had both had easily molded, overlap joint jail, so as to
Improve the intensity and quality of optical cable；It can save material, reduce cost simultaneously.In the present embodiment the preferred low cigarette of fire-retardant set 7 without
The fire-retardant set of halogen.In order to increase the stiction between fire-retardant set 7 and enhancement layer 6, the lateral wall of enhancement layer 6 is provided with several mutual
Parallel fin 61.When fire-retardant set 7 is set in the outer wall of enhancement layer 6, enhancement layer 6 can be applied to fire-retardant set 7 towards outside
Thrust, the fin 61 being arranged on the outer wall of enhancement layer 6 paste enhancement layer 6 and fire-retardant set 7
That closes is even closer；In stripping fiber optic cables, since there are biggish stiction between enhancement layer 6 and fire-retardant set 7, so that reinforcing
Layer 6 is easier to separate with the movement of fire-retardant set 7 with optical fiber body 1.
Referring to Figures 1 and 2, in order to increase the fitting area between fire-retardant set 7 and enhancement layer 6, fin 61 is close to fire-retardant set 7
The arc-shaped setting in end.
Referring to Figures 1 and 2, fire-retardant set 7 is provided with several protruding portions 8 close to the inner sidewall of enhancement layer 6, protruding portion 8 according to
A certain distance is uniformly spaced setting.Protruding portion 8 includes and the integrally formed bottom 81 of fire-retardant set 7 and is embedded on bottom 81
Puncture portion 82.Bottom 81 has certain elastic force, can generate certain elastic deformation, bottom 81 is close to enhancement layer 6
End is embedded with puncture portion 82, and puncture portion 82 can be plugged into inside enhancement layer 6.In order to increase the relatively steady of 8 position of protruding portion
Qualitative, enhancement layer 6 offers the groove 62 for being embedded protruding portion 8, groove 62 and the setting of the interval of protruding portion 8.While in order to subtract
Few influence of the groove 62 to 6 intensity of enhancement layer, the cross section V-shaped setting radial along enhancement layer 6 of groove 62；62 edge of groove simultaneously
The direction setting parallel with the axis of enhancement layer 6.The biggish metal material of material preferred hardness in puncture portion 82 in the present embodiment.
During using hoe scaler stripping fiber optic cables, hoe scaler can be applied to optical cable inside extruding during clamping optical cable
Power, fire-retardant set 7 generates elastic deformation under the action of extruding force, while puncture portion 82 is pierced into enhancement layer 6 under the action of extruding
It is internal.Be embedded puncture portion 82 inside groove 62 can with fire-retardant set 7 removing groove 62 interior slip, thus will
Enhancement layer 6 and non-metal reinforced layer 5 are cut, to facilitate the stripping of optical cable.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
