It includes fiber optic plug and optical cable, and the optical cable contains fiber cable jacket, and the fiber cable jacket overcoat is equipped with steel armour pipe, and one section distance cover of steel armour outside of tubes every is equipped with a conducting ring, and the conducting ring is equipped with the opening, and the inner ring in close contact with steel armour pipe of conducting ring, every conducting ring are divided equally and is do not welded the cord that is used for ground connection. The conducting ring still overlaps outward and is equipped with the protective sheath. The protective sheath is the protective sheath of metal. The protective sheath is the tubular metal resonator. Not only can protect the inside wire rod of optical cable not receive the mouse to suffer from harm, further can protect fiber cable jacket also not suffered from harm by the mouse, and can waterproof and protection optical cable inner structure, can carry out ground connection with being equipped with direct the cup jointing in the steel armour pipe that exposes outer from the opening part of open -ended conducting ring, make the optical cable have protection against rodents lightning proof effect concurrently, the inner ring in close contact with steel armour pipe of conducting ring, the ground structure is more simple direct, is fit for bulk production, and makes things convenient for the site operation, is fit for popularization and application.
Description
Technical field
The utility model belongs to dragging optical cable technical field, specifically, relates to protection against rodents lightning protection dragging optical cable and cable assembly.
Background technology
Along with Chinese 4G optical fiber is to tower and LTE(Long Term Evolution) development, base station will certainly be built in a large number, for the dragging optical cable communicated to connect between base station and base station, particularly the dragging optical cable consumption of outdoor cover is increasing, remote technology generally uses distribution-type base station architecture, needs to use Fiber connection between RRU (radio frequency remoto module) and BBU (baseband processing unit).Zoom out distance and be generally 100 ~ 300 meters, wherein one end is positioned at base station, and the other end is positioned at intra-office, because its major part is in outdoor, mouse and other muroid inevitably work the mischief to the normal transmission of optical cable, and therefore dragging optical cable product needed considers the function of protection against rodents simultaneously.
In prior art, the practical method of protection against rodents adopts steel armour pipe, can prevent the destruction avoiding most of muroid to optical cable.But use steel armour pipe protection against rodents introduces a new problem simultaneously, because steel armour pipe can conduct electricity, launching tower is likely received by cable assembly after introducing thunder and lightning, thus along the steel armour pipe transmission in optical cable, final destruction optical cable or miscellaneous equipment, serious can fire hazard.Therefore the Lightning Protection that a kind of scheme solves protection against rodents dragging optical cable is urgently proposed.
Summary of the invention
The utility model overcomes shortcoming of the prior art, provides protection against rodents lightning protection dragging optical cable and cable assembly, has the function of protection against rodents and lightning protection concurrently, and structure is simple, is applicable to batch production and extensively promotes.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Protection against rodents lightning protection dragging optical cable and cable assembly, comprise Optical fiber plug and optical cable, optical cable comprises cable jacket, steel armour pipe is arranged with outside cable jacket, steel armour pipe is outer is arranged with a conducting ring every a segment distance, conducting ring is equipped with opening, and the inner ring close contact steel armour pipe of conducting ring, each conducting ring is welded with the cord for ground connection respectively.
Further, conducting ring is also arranged with protective sleeve outward.
Further, protective sleeve is the protective sleeve of metal.
Further, the protective sleeve of metal is metal tube.
Wherein, conducting ring is welded in steel armour pipe.
Further, the opening part of conducting ring, the two-end-point of close steel armour pipe are welded in steel armour pipe.
Cord is welded in the opening part away from conducting ring.
Cord and optical cable be arranged in parallel.
Compared with prior art, the beneficial effects of the utility model are:
Protection against rodents lightning protection dragging optical cable described in the utility model and cable assembly, comprise Optical fiber plug and optical cable, optical cable comprises cable jacket, steel armour pipe box is located at the outside of cable jacket, the inner wire rod of optical cable not only can be protected not suffer from harm by mouse, cable jacket can be protected further also not suffered from harm by mouse, and the conducting ring being provided with opening directly can be socketed on exposed steel armour pipe from opening part and carry out ground connection, optical cable is made to have protection against rodents concurrently, lightning protection, waterproof effect, the inner ring close contact steel armour pipe of conducting ring, ground structure is more simple directly, be applicable to a large amount of production, and facilitate site operation, be applicable to applying.
