Abstract
The utility model discloses a field quick connector for installing communication optical fibers. The field quick connector comprises a shell body. An optical fiber connecting head is arranged in the shell body, and a tail handle is arranged behind the optical fiber connecting head. An inner core assembly for inserting the optical fiber is arranged in the tail handle, and a locking piece for fixing the optical fiber in the inner core assembly is sheathed outside the tail handle. The field quick connector has the advantages that in field installation, a bare optical fiber is directly inserted into an optical fiber groove of the inner core assembly, then the optical fiber in the inner core assembly is locked by the locking piece to be abutted with the optical fiber in the optical fiber connecting head, therefore, the purpose of quickly connecting the communication optical fibers is achieved, and the waste caused by the overlong optical fiber cable is avoided. Compared with the traditional structure, the field quick connector has simple structure and low production cost.
Description
Technical field
The utility model relates to a kind of telecommunication optical fiber connector, relates in particular to the on-the-spot quick coupler of installing of a kind of telecommunication optical fiber.
Background technology
Optical fiber communication is applicable in the various application that comprise voice communication, data transmission or the like.In the optical fiber telecommunications system process was installed, the connection of telecommunication optical fiber need be used the telecommunication optical fiber connector for convenience.Existing telecommunication optical fiber connector is assembled in advance in factory mostly and is finished, and directly can use at the scene.But because needed length difference is installed at the scene, assemble traffic carried optical fiber in advance because oversize and cause certain waste, thereby need the on-the-spot quick coupler of installing of a kind of telecommunication optical fiber, its advantage is easy to operate, avoid unnecessary waste, but the following problem of existing quick coupler ubiquity: the structure more complicated, production cost is than higher.
Summary of the invention
Technical problem to be solved in the utility model provides the on-the-spot quick coupler of installing of a kind of telecommunication optical fiber simple in structure, low cost of manufacture.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the on-the-spot quick coupler of installing of a kind of telecommunication optical fiber, comprise housing, be provided with fiber connector in the described housing, be provided with caudal peduncle behind the described fiber connector, it is characterized in that being provided with in the described caudal peduncle the interior core assembly that can insert optical fiber, described caudal peduncle is arranged with the locking member that the optical fiber in the interior core assembly is fixing outward.
Core assembly comprises inner core and following inner core in described, described inner core first side of going up is provided with optical fiber duct, described second side of going up inner core is provided with convex tendon, described inner core down has seal face, and described seal face and described first side with optical fiber duct cooperatively interact, and described convex tendon stretches out described caudal peduncle outer peripheral face, described locking member inwall comprises arcwall face and plane, rotational lock spare, when described plane and described convex tendon at once, will go up inner core and lock with following inner core.
Described going up on inner core and the following inner core is respectively arranged with the optical fiber gathering sill.
Described fiber connector comprises protheca and the lock pin that is arranged in the housing, before described lock pin is fixed on described caudal peduncle, is arranged with spring on the described caudal peduncle, and the optical fiber of described lock pin extands rearward in the optical fiber duct.
Described caudal peduncle is provided with the back cover, and clamping sleeve, tail cover and optical fiber cable are set behind the described caudal peduncle.
Described lock pin front end is provided with dust cap.
Compared with prior art, the utility model has the advantages that when installing at the scene, directly bare fibre is inserted in the optical fiber duct of interior core assembly, with locking member the optical fiber in the interior core assembly is pinned then, with the fiber alignment in the fiber connector, thereby reach the purpose of quick connection telecommunication optical fiber, avoided the waste that causes because of optical fiber cable is long.It is simpler that the utility model is compared traditional structure, and production cost is lower.
When the convex tendon on the last inner core is aimed at the arcwall face of locking member, last inner core does not compress mutually with following inner core, can insert bare fibre in the optical fiber duct this moment, rotation lock part certain angle then, make the interior plane of locking member push down the convex tendon of inner core, to go up inner core and the locking of following inner core, thereby optical fiber will be fixed.
