Description
Technical field
The utility model is related to a kind of compound buried cable for airport flight assistant lamp light circuit of optical fiber, belongs to cable and prepares skill
Art field.
Background technology
Buried cable for airport flight assistant lamp light circuit, is a kind of cable that electric power is provided as airfield aid.It is existing
Buried cable for airport flight assistant lamp light circuit from inside to outside structure be conductor, inner shield, insulating barrier, external shield, metal screen layer,
Belting layer, restrictive coating, wherein inner shield, insulating barrier, external shielding layer use plastic materials, and metal screen layer is then using naked
Proof copper-wire braided structure.
It is not to be directly laid in pipeline so that cable runs into vole etc. because cable is directly to be buried under lawn
The increase of rodent probability, in order to prevent the destruction to cable of mouse, conventional method is the sheath material in cable at present
Synthesis pungent element is added in material, when mouse stings cable cover(ing), pungent element can to feel bad in mouse oral cavity and stop continuing to sting
Cable.
Existing cable has the disadvantage that：
（1）Cable flexibility is poor.Because interior screen, insulation and outer screen material used in cable are plastics in the prior art
Class material, conductor is the 2 class conductors used in addition, therefore the overall flexibility of cable is poor, and the bending radius of cable is big, in peace
When filling and laying, for needing the small place in bend region, cable is easily damaged.
（2）Production cycle is long.The metal screen layer of cable uses proof copper-wire braided shielding, screen layer needs braiding
Machine weaves, and braiding speed is slow, many using material, adds the production cycle of cable.
（3）Protection against rodents effect is poor.Because the mode of the synthesis pungent element in sheath belongs to chemical mode, pushing away over time
Move, synthesis pungent element can fade away, so as to lose rodent-proof characteristic.
（4）Production is not environmentally.Pungent element is synthesized to add in sheath material, to the skin of direct labor, respiratory tract all spinosities
Swash, have injury to human body.
（5）Without block-water performance.Once cable is without any stop water, cable cover(ing) damaged, and water can enter inside cable, plus
Other of fast cable are component aging, reduce the service life of cable.
（6）Buried cable for airport flight assistant lamp light circuit can only be used as power transmission in the prior art, and airport is helped
The control of boat lamp then needs the other cable for laying signal transmission class, the cable separately laid add lay intensity and when
Between.

State and soft copper belt is surrounded with outside insulation screen, first is surrounded with outside the soft copper belt and is blocked water yarn layer, first water blocking yarn
Layer is outer to be surrounded with the first glass fiber belt that thickness is 0.9-1.1mm, is equipped with thin along making a circle in week for the first glass fiber belt
Steel wire floor, finer wire layer outer wrapped second blocks water yarn layer, and described second, which blocks water, is surrounded with thickness for 0.9-1.1mm outside yarn layer
The second glass fiber belt, be extruded with restrictive coating outside the second glass fiber belt.
Further, the insulating barrier, insulation screen and the wrapped conductor of soft copper belt and the fiber unit of conductor both sides,
And raise up to form one section of arc-shaped in the position of fiber unit.
Further, described first block water yarn layer outside it is wrapped rounded.
Further, the conductor is not more than 0.31mm tinned copper wire by 1+6 stranded mode system using filament diameter
Into.
The utility model is simple in construction, compact to design, and fiber unit is extruded in insulating barrier, realizes the signal of cable
Transfer function, fiber unit will not be by electromagnetic interference, therefore does not need any screen layer, and cable weight is light, layer glass silk
Belt adds protection against rodents effect, and first blocks water yarn layer and the second setting for blocking water yarn layer adds the water resistance of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference：Conductor 1, conductor shield 2, insulating barrier 3, insulation screen 4, fiber unit 5, soft copper belt 6,
One block water yarn layer 7, the first glass fiber belt 8, finer wire layer 9, second blocks water yarn layer 10, the second glass fiber belt 11, restrictive coating

Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in figure 1, a kind of compound buried cable for airport flight assistant lamp light circuit of optical fiber, including positioned at cable center
Conductor 1, the tinned copper wire that conductor 1 is not more than 0.31mm using filament diameter is made by 1+6 stranded mode, is used on conductor 1
Three-layer co-extruded mode disposably extrudes conductor shield 2, insulating barrier 3 and insulation screen 4, and the both sides of conductor 1 are respectively arranged with
Fiber unit 5, fiber unit 5 is arranged in insulating barrier 3, insulating barrier 3, insulation screen 4 and the wrapped and of conductor 1 of soft copper belt 6
The fiber unit 5 of the both sides of conductor 1, and raise up to be formed outside one section of arc-shaped, insulation screen 4 in the position of fiber unit 5
Be surrounded with soft copper belt 6, first be surrounded with outside soft copper belt 6 and is blocked water yarn layer 7, first block water yarn layer 7 outside it is wrapped rounded,
First, which blocks water, is surrounded with the first glass fiber belt 8 that thickness is 0.9-1.1mm outside yarn layer 7, along around the first glass fiber belt 8
One circle is equipped with outside finer wire layer 9, finer wire layer 9 wrapped second and blocked water yarn layer 10, and second, which blocks water, is surrounded with thickness outside yarn layer 10
For 0.9-1.1mm the second glass fiber belt 11, the second glass fiber belt 11 is extruded with restrictive coating 12 outside.
Design principle of the present utility model：
1. improve the flexibility of cable
The flexibility and resist bending ability of cable depend primarily on the structure of cable, and the conductor wire core in the construction of cable
Structure plays vital effect again.In order that conductor wire core is soft, resist bending, with higher conductance, this practicality is new
Type is not more than 0.31mm tinned copper wire using filament diameter；1+6 regular stranded mode is used during process, makes conductor structure
More stable, tightness degree is high, and external diameter is small, and conductor wire core pliability is good.Conductor shield, insulating barrier, insulation in the utility model
Screen layer is using pliability very high elastomeric material so that the integrally bending of cable is fine.
2. the production cycle
It is shielding construction only with one layer of soft copper belt, and its technique is, around packet mode, to greatly reduce the production cycle.
3. strengthen the environmental-protecting performance of rodent-proof characteristic and production
In order to take into account the feature of environmental protection and protection against rodents property, the utility model is provided with layer glass ribbon layer and finer wire in cable
Layer, glass fiber belt and finer wire layer the discomfort on body will not be brought to direct labor, glass fiber belt when mouse bites,
Tiny acicular texture can be with shouting pain mouse in glass tape so that mouse stops biting, while finer wire layer is larger due to hardness,
Mouse is difficult that the protection against rodents effect that bites is more preferable.
4. water resistance
Two layers of yarn layer that blocks water is provided with inside cable, when cable cover(ing) damages or hurts seizing wire, and is had
When water enters the cable Rotating fields, this Rotating fields can expand in breakage, fill out damage location, prevent water from entering inside cable,
Realize the water resistance of cable.
5. optical fiber is combined
Fiber unit is extruded in insulating barrier, the signal transfer functions of cable are realized, and fiber unit will not be by
The influence of electromagnetic interference, therefore any screen layer need not be set, cable it is lightweight.
