Abstract
In order to overcome not enough that current communication cable exists, the utility model provides a communication cable, the utility model discloses a cable core, outer jacket, plastic fiber, insulating layer, shielding layer, sheath, sensing element, this communication cable can determine the position that the cable broke down through the information of sensing element repayment, make things convenient for breakdown maintenance.
Description
Technical field
This utility model relates to a kind of field of cables device, a kind of can judge, by the information of sensing element feedback, the position that cable breaks down, and facilitates the communication cable of breakdown maintenance.
Background technology
Along with the progress of science and technology, the communications industry has obtained bigger development, and the application of communication cable is more and more extensive；Communication cable is for transmitting phone, telegram, fax paper, TV and broadcast program, data and the cable of other signals of telecommunication, it is the wire by many mutual insulatings or the cable heart that conductor is twisted into and the protection cable heart do not make moist the communication line that the outer protective sleeve with mechanical damage constituted, it includes cable core and the outer jacket being positioned at outside cable core, the quantity of cable core is set to different numbers according to its use demand, its mounting means has built on stilts, direct-burried, the multiple system of layings such as pipeline and the bottom, and communication system generally all includes for concentrating wiring, the communication cable processed collects end and is dispersed in each different use ends using region.Telecom cable production factory distribution all parts of the country.China is in addition to the long-distance type communication cable of production and city words cable, and fiber optic cables and polyolefin insulation integrated sheath overall plastic city words cable there has also been significant progress, domestic many producers and R&D institution to start to produce with equipment from external imported technology.China has a small amount of polyolefin insulation polyolefin jacket plastic telephone cable to sell to the ground such as Hongkong and Macro, Southeast Asia and the Middle East every year.
At present, known communication cable structure is to include cable core, outer jacket, plastic optical fiber.This communication cable can not directly judge the accurate location of cable fault, it has not been convenient to maintenance.
Summary of the invention
For the deficiency overcoming existing communication cable to exist, this utility model provides a kind of communication cable, and this communication cable can judge, by the information of sensing element feedback, the position that cable breaks down, facilitate breakdown maintenance.
This utility model solves the technical scheme is that this utility model of its technical problem and includes cable core, outer jacket, plastic optical fiber, insulating barrier, screen layer, sheath, sensing element.
This device includes cable core and the outer jacket being positioned at outside cable core, and described cable core is metal optical cable；Being additionally provided with a plastic optical fiber in described outer jacket, outer jacket is transparent or semitransparent material, and described outer jacket includes insulating barrier, screen layer and the sheath being arranged concentrically from inside to outside；Equipped with sensing element inside described sheath, this sensing element, according to a certain distance, is evenly distributed in whole communication cable, and is connected by the internal cable core of circuit and cable, and it is provided with wireless launcher.
Described insulating barrier is polyethylene layer.
Described screen layer is laminated film such as aluminium foil or the metal wire knitted stratum reticulare of band metal material.
Described sheath is polyethylene or vinyl chloride sheath.
The beneficial effects of the utility model are, can judge, by the information of sensing element feedback, the position that cable breaks down, facilitate breakdown maintenance.

Detailed description of the invention
At Fig. 1, in 2 illustrated embodiments, this utility model includes cable core (1), outer jacket (2), plastic optical fiber (3), insulating barrier (4), screen layer (5), sheath (6), sensing element (7).
This device includes cable core (1) and is positioned at cable core (1) outer jacket (2) outward, and described cable core (1) is metal optical cable.A plastic optical fiber (3) it is additionally provided with in described outer jacket (2), outer jacket (2) is transparent or semitransparent material, and described outer jacket (2) includes insulating barrier (4), screen layer (5) and the sheath (6) being arranged concentrically from inside to outside；Described sheath (6) is internal equipped with sensing element (7), this sensing element (7) is according to a certain distance, it is evenly distributed in whole communication cable, and is connected by the internal cable core (11) of circuit and cable, it is provided with wireless launcher.This wherein, described insulating barrier (4) is polyethylene layer (4)；The described laminated film such as aluminium foil that screen layer (5) is band metal material or metal wire knitted stratum reticulare；Described sheath (6) is polyethylene or vinyl chloride sheath.
When being embodied as, collect end or use end that plastic optical fiber (3) is applied light source, plastic optical fiber (3) in this communication cable will be shinny, such that it is able to be able to conveniently find the position of this root communication cable other end, time breaking down in cable somewhere, the sensing element (7) at fault two ends can transmit signals to maintenance terminal by wireless launcher, and then determines abort situation, installs maintenance more convenient.
As known by the technical knowledge, this utility model can be realized by the embodiment of other essence without departing from its spirit or essential feature.
Embodiment disclosed above, for each side, is all merely illustrative, and is not only.All all it is included in the utility model in the range of this utility model or being equal to the change in the range of this utility model.
