Abstract
The utility model discloses a cavity-type elevator trailing optical cable comprising a flat soft flame-retardant jacket, wherein a cavity is arranged in the middle of the flat flame-retardant jacket; a plurality of communication optical cables are arranged in the cavity; two power lines and two steel strands are also arranged in the flat soft flame-retardant jacket; the two power lines are symmetrically arranged in the two sides of the cavity; the two steel strands are symmetrically arranged in the two sides in the flat soft flame-retardant jacket; and the cavity, the power lines and the steel strands are arranged side by side along the flat direction of the flat soft flame-retardant jacket. The cavity-type elevator trailing optical cable uses the communication optical cable to replace the traditional video cable and control cable, thus having small volume, light weight, high anti-interference capacity and low signal distortion rate, furthermore, the cavity provides enough space for the activity of the communication cable, and the tensile force of the whole cable is born by the steel strands during the process for lifting the elevator so as to guarantee that each component, including the communication cable, in the cavity-type elevator trailing optical cable is not damaged during the process for lifting the elevator.
Description
Technical field
The utility model relates to a kind of optical cable, relates in particular to a kind of elevator trailing optical cable.
Background technology
Being used for video monitoring, voice delivery and control in the elevator at present, all is to adopt traditional elevator cable, this cable Heavy Weight; Volume is big, and signal transmission performance is low, and the highest have only the 8MHz bandwidth; And be subject to external magnetic field and disturb, make distorted signals, such as because the interference that the variable-frequency governor of interference that the up-down of elevator causes and elevator employing itself causes; And elevator moves up and down, and trailing cable needs often bending one stretching, thereby cable is fractureed easily or breaks and damage.
The utility model content
The purpose of the utility model is a kind of cavity type elevator trailing optical cable is being provided, and it is in light weight, volume is little, antijamming capability is strong, signal distortion rate is low, and in the elevator lifting process, can not be damaged.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of cavity type elevator trailing optical cable; Comprise the soft fire retardant jacket of a flat, be provided with a cavity in the middle of the said flat fire retardant jacket, be provided with many telecommunication optical fibers in the cavity; In the soft fire retardant jacket of said flat, also be provided with two power lines, steel strand wire; Wherein two power lines are symmetricly set in said cavity both sides, and said two steel strand wire are symmetricly set in the inner both sides of the soft fire retardant jacket of flat, and said cavity, power line, steel strand wire are along the flat direction setting of the soft fire retardant jacket of flat.
The position of the corresponding cavity in the soft fire retardant jacket of said flat both sides, power line and steel strand wire respectively has two " V " shape wire stripping grooves.
After adopting technique scheme, during use, volume is little; In light weight, antijamming capability is strong, thereby signal distortion rate is low; And cavity is that the activity of telecommunication optical fiber provides enough spaces, thereby guarantees that in the lifting process of elevator telecommunication optical fiber can not receive pulling force and damages, and in the elevator lifting process; The pulling force of whole optical cable is born by steel strand wire, further guarantees can not make each parts of the utility model to receive pulling force and damages.
Description of drawings
Fig. 1 is the utility model cavity type elevator trailing optical cable schematic cross-section.
Embodiment
Below will specify cavity type elevator trailing optical cable with reference to accompanying drawing according to the utility model embodiment.
As shown in Figure 1; The utility model cavity type elevator trailing optical cable comprises the soft fire retardant jacket 1 of a flat; Be provided with cavity 2 in the middle of the said flat fire retardant jacket 1, be provided with many telecommunication optical fibers 3 in the cavity 2, in the soft fire retardant jacket 1 of this flat, also be provided with two power lines 4, steel strand wire 5; Wherein two power lines 4 are symmetricly set in said cavity 2 both sides; Said two steel strand wire 5 are symmetricly set in the inner both sides of the soft fire retardant jacket of flat 1, and said cavity 2, power line 4, steel strand wire 5 promptly are arranged side by side along the flat direction setting of the soft fire retardant jacket 1 of flat.Corresponding each position component in the soft fire retardant jacket of said flat 1 both sides respectively has two " V " shape wire stripping grooves 6, thereby makes easy for installation.Said power line 4 is used to the video frequency pick-up head and the power supply of language intercom of elevator lighting and monitoring usefulness, and said steel strand wire 5 are used to carry the weight of optical cable own.
The utility model adopts telecommunication optical fiber 3 to replace traditional video line and control line, has alleviated the weight and volume of retinue optical cable self widely, because traditional video line all is to adopt coaxial cable; The volume of this cable is big, Heavy Weight, and telecommunication optical fiber 3 volumes are little; In light weight; In the present embodiment, preferably, employing have only the silicon dioxide telecommunication optical fiber 3 of 0.25mm for diameter.And because the signal transmission of telecommunication optical fiber 3 is to utilize optical transmission; The sort signal transmission means is not vulnerable to external magnetic field and disturbs; Comprise that because the interference that the variable-frequency governor of interference that the up-down of elevator causes and elevator employing itself causes, antijamming capability is strong, thereby signal distortion rate is low.
Described cavity type elevator trailing optical cable and since optical cable constantly along with elevator up and down and constantly crooked-stretching because the body of telecommunication optical fiber 3 is a silicon dioxide; It is quartz glass; Expansion and contraction no better than zero, and telecommunication optical fiber 3 can not be drawn high and pushed in communication process, and adopt cavity 2 structures; Just, guarantee that telecommunication optical fiber 3 can not drawn high and push and damage in the lifting process of elevator for the activity of telecommunication optical fiber 3 provides enough spaces; And the utility model cavity type elevator trailing optical cable adopts each parts to be arranged side by side at the mode in the soft fire retardant jacket 1 of flat; And steel strand wire 5 are symmetricly set in both sides; Thereby in the elevator lifting process; The pulling force of whole optical cable is born by steel strand wire 5, further guarantees can not make each parts of the utility model can not damage.
