Description
Technical field
The utility model relates to optical fiber communication accessory technical field, specifically refers to a kind of SC type rubber-insulated wire welded-connecting type optical fiber quick connector.
Background technology
In the fiber entering household engineering, the work that continues of optical fiber is generally finished by quick coupler, and quick coupler is also referred to as articulation, common are two kinds on FC type and SC type.Two kinds of links corresponding to joints of optical fibre difference, SC type rubber-insulated wire welded-connecting type optical fiber quick connector of the prior art is widely used as a kind of FC connector, but SC type rubber-insulated wire welded-connecting type optical fiber quick connector of the prior art has the following disadvantages: being connected between optical fiber rubber-insulated wire of the prior art and the adapter sleeve mainly is the screw cap type connected mode that adopts, in the screw cap type syndeton, by the tapered plastic cap of screwing at the afterbody of adapter sleeve, with the snap-in force that plastic cap screws between rear and the plastics adapter sleeve rubber-insulated wire is pushed down.But this connected mode maximum bearing tension only has 3～5 kgfs (being roughly equal to 30～50 Ns), and strength of joint is low, poor reliability.
The utility model content
The technical problems to be solved in the utility model is that the SC type rubber-insulated wire welded-connecting type optical fiber quick connector of a kind of strength of joint height, good reliability is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of SC type rubber-insulated wire welded-connecting type optical fiber quick connector, it comprises housing, protheca, lock pin, caudal peduncle, spring, cover after welding connects, welded pipe, rear cover and tail cover, lock pin is inserted in the protheca, the right-hand member of lock pin is connected with caudal peduncle, spring is against caudal peduncle and is connected with welding between the rear cover, the right-hand member of cover was extended with one section optical fiber after welding connected, described optical fiber is enclosed within the welded pipe, rear cover is positioned at the right-hand member of welded pipe, the right-hand member of rear cover is connected with the tail cover, described rear cover right-hand member is provided be used to the sleeve pipe that entangles the optical fiber rubber-insulated wire, described sleeve pipe is provided with block button hole, is provided with in the described block button hole for the buckle that the optical fiber rubber-insulated wire is clamped on the sleeve pipe.
After adopting above structure, the utlity model has following advantage: described rear cover right-hand member is provided be used to the sleeve pipe that entangles the optical fiber rubber-insulated wire, and described sleeve pipe is provided with block button hole, is provided with in the described block button hole for the buckle that the optical fiber rubber-insulated wire is clamped on the sleeve pipe.First buckle is taken out during concrete the use, again rubber-insulated wire optical fiber is pierced into the rubber-insulated wire sleeve pipe, then by instrument buckle is compressed into the buckle jack, buckle pierces through rubber-insulated wire, so contact very firm, simultaneously because buckle is to be stuck in the buckle jack, the top of buckle is to cooperate with the inwall of buckle jack is spacing, just be difficult to after in a single day rubber-insulated wire is stuck transfer to, also be not easy to rotate, but the maximum bearing tension can reach 100 Ns～120 Ns, so it is higher to connect the strength of joint of rubber-insulated wire optical fiber, and better reliability.
As improvement, described buckle is four pin buckles, it comprises a square principal plane and four card bases, and described four card bases lay respectively on four angles of square principal plane, and described four card bases are positioned at the same side of square principal plane and vertical with square principal plane.This structure is easy to process, and also very convenient during clamping, the strength of joint of four card bases is also larger.
As preferably, it also comprises dust cap, and dust cap is socketed in the left end of housing.This structure in connector is not linked into respective socket the time dust be difficult for entering in the connector, further optimized reliability.
