Description
Technical field
The utility model relates to cable, is specifically related to a kind of cable that is used for elevator.
Background technology
In order to realize real-time monitoring and the multimedia messages transmission in the elevator cage, contain communications optical cable and video coaxial cable in the trailing cable of elevator more.
The ordinary optic fibre telecommunication cable, advantage such as because of it is little to signal attenuation, transmission capacity is big, and antijamming capability is strong is widely used in the communications field.But because the flexibility and the bendability of this class cable are relatively poor, this class cable is as using in the trailing cable in elevator hoistways, reasons such as meeting Yin Lali, wall pressure, in very short time, cause the optical cable transmission attenuation to increase and disconnected core phenomenon, so the ordinary optic fibre telecommunication cable is not suitable in the trailing cable.
The utility model content
The purpose of this utility model is, provides elevator with the retinue optical fibre communication cable, solves above technical matters.
The technical matters that the utility model solved can realize by the following technical solutions:
Elevator comprises optical cable fibre core, interior tegillum, serving, outer jacket from inside to outside with the retinue optical fibre communication cable, it is characterized in that described outer jacket also is provided with a finer wire braid outward.
Can improve tensile strength of the present utility model by the finer wire braid is set, anti-pressure ability and resistance to bend(ing) energy have solved problems such as optical cable fibre core loss under the alternating bending squeezed state increases, easily chaps and fracture.
Described serving adopts nylon sleeve.
Described optical cable fibre core adopts multimode optical fiber.Its operating wavelength range is 850～1300nm, and the optical cable core diameter is 62.5um, optical cable fibre core peripheral hardware one covering, and the overall diameter of covering is 125um.
Described optical cable fibre core also can adopt single-mode fiber.
It is the outer jacket of material that described outer jacket can adopt aramid yarn.Adopt aramid yarn can improve stretching resistance of the present utility model, reduce the stressed of optical cable fibre core.
Described finer wire braid is outer can also to be provided with a sheath, the insulating sheath that described sheath can adopt the potteryization silastic material to make.The potteryization silastic material not only has Halogen, nontoxic, tasteless, low cigarette, high-low temperature resistant characteristic, also has good flame-retardant performance, before unburned, also has flexibility and elasticity preferably.
Compared with prior art, beneficial effect of the present invention:, the utlity model has good flexibility, anti-pressure ability and resistance to bend(ing) and can wait advantage by force owing to adopt technique scheme.By the test method of stipulating in GB/T5023.2-2008 and the EN 50214-2006 standard that deflects, through after 30,000 bending tests, its transmission performance can also satisfy the national standard requirement fully, and its machinery deflects performance and is better than in GB GB/T 5023.2-2008 and the EN 50214-2006 of the European Union standard bending property requirement to product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
