Description

A kind of optical fiber quick connector

[technical field]

The utility model relates to a kind of connector, especially relates to a kind of optical fiber quick connector.

[background technology]

In optical communication network, often need continue to optical fiber, fibre junction has dual mode, and a kind of is the welding tail optical fiber, also claims the hot joining mode.Adopt the fusing mode cost high, equipment carries inconvenience, and operating speed is slow, and efficient is low, and operating environment is had higher requirement.Another kind of cold joint mode, can not use dress with instrument with succinctly efficiently mode optical fiber is carried out permanent connection, and receive the influence of installation environment hardly.Therefore, now optical fiber is connected the mode that basically all adopts cold joint.

But, adopt existing fiber cold joint equipment installation step more loaded down with trivial details, and complicated, and constant often, unadjustable to the clamping force of optical fiber rubber-insulated wire.

Often to use the connection between optical cable and the tail optical fiber in the optical fiber communication.Method now commonly used is to adopt the optical fiber fusing soldering welder that the optical fiber of one of tail optical fiber and the optical fiber in the optical cable are connected together fixed connection disposably and permanently just after with the electric arc hot melt.

But this mode also exists very big weak point.At first, in the work progress optical fiber fusing soldering welder must be arranged, need commercial power supply.If there is not power supply, must carry generator.Secondly, enough operating spaces and platform must be arranged, run into when making somebody a mere figurehead operation, must be after welding be accomplished on ground with equipment, built on stilts again fixing.Moreover this form of construction work is more consuming time, and cost is also higher.Bring raising and operating efficiency low of network construction cost thus.

Along with developing rapidly of optical fiber communication, Fiber to the home has been mentioned the enforcement schedule, but traditional single mode fiber cable has suitable flexibility; Through walls register one's residence inapplicable; So the bigger covered wire cable of hardness has been arranged, to hand in the box but will be connected to fiber cable cross connection box or light after through walls the registering one's residence, the optical cable port needs at the scene without power supply, does not need under the situation of milling apparatus; The connector that continues needs a optical fiber quick connector at present and replaces the connector on the traditional market.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of optical fiber quick connector, it is characterized in that, and comprise the group of ceramics component; It is made up of V bottom land seat, dog catch, main body, inner casing, ceramic insertion core and dog catch, is provided with optical fiber in the said ceramic insertion core; Rear support; Comprise fastening subassembly and rubber-insulated wire chucking subassembly; Said fastening subassembly comprises the axis of guide, be arranged on hollow tubular in the axis of guide, be arranged on the V-type bayonet socket of axis of guide rear end and be nested with the spring of V-type bayonet socket end on the axis of guide, and said rubber-insulated wire chucking subassembly comprises the inserted sheet that is fixed on the bare fibre and near the limited block that is used for fixing the covered wire cable external diameter at the bare fibre place; Lock sleeve, it is nested with the outside of said rear support and with said group of ceramics component and is connected locking.

Preferably, said group of ceramics component and said lock sleeve are through the locking that is threaded.

Preferably, the xsect of said V-type bayonet socket is circular, and the angle that the longitudinal section of said V-type bayonet socket forms is the 25-45 degree.

Preferably, the angle of the longitudinal section of its V-type bayonet socket formation is the 30-40 degree.

Preferably, the angle of the longitudinal section of its V-type bayonet socket formation is 35 degree.

The utility model beneficial effect compared with prior art is: because rear support is provided with fastening subassembly and rubber-insulated wire chucking subassembly; Can make things convenient for the quick optical fiber that is connected through fastening subassembly and rubber-insulated wire chucking subassembly, the utlity model has easy and simple to handle, connect accurately, signal attenuation is weak and the high advantage of merging precision.
