Abstract
The utility model relates to the technical field of an optical element, in particular to a short tail pipe used for an LC optical fiber connector joint. The short tail pipe comprises a body provided with a cylindrical inner cavity, an outer surface of one end of the body is contracted inside, a chamfer is formed, and a circular cable inlet hole is formed at the outer edge of the chamfer. The short tail pipe has the advantages that: the short tail pipe can be used under a narrow environment in effective placing space outside an optical connector of communication equipment, compare with the common LC optical fiber connector, equipment space can be saved by 1/3, and miniaturization and integration of the equipment can be more convenient.
Description
Technical field
The utility model relates to field of optical device technology, is specifically related to a kind of LC fiber active linker joint and uses stub liner.
Background technology
In the fiber optic cables communications field; Need be applied to the fiber active linker joint under many environment; Under some particular environment, limited like spatial area, or environment such as the integrated higher wiring space of optical fiber distributing cabinet is little; May cause problems such as ODF rack cabinet door can't be closed, long tail pipe extruding optical fiber increase loss with common LC type fiber active linker, the utility model will effectively address the above problem.
Summary of the invention
The purpose of the utility model provides a kind of narrow and small environment use down of the outside effectively placement space of optical interface in the communication facilities that is used for; Can be than the device space of the effective saving 1/3 of common LC fiber active linker, the miniaturization of more convenient equipment and integrated LC fiber active linker joint are used stub liner.
The realization of the utility model is accomplished by following technical scheme:
A kind of LC fiber active linker joint is used stub liner, it is characterized in that: said stub liner comprises that one has the body of cylindrical shape inner chamber, and the outside surface of said body one end inwardly shrinks to form chamfering, and said chamfering outer rim constitutes circular cable and gets into the hole.
Said body and chamfering thereof are that the elastic flame plastics are via the molded integrative-structure that constitutes.
Type roughly is round table-like moulding outside the said chamfered section.
Said cable gets into hole and the coaxial setting of the cavity of said body.
The utility model has the advantages that: can be in communication facilities the narrow and small environment of the outside effectively placement space of optical interface use down, can be than the effective device space of saving 1/3 of common LC fiber active linker, the miniaturization of more convenient equipment and integrated.
Description of drawings
The contrast of Fig. 1 the utility model and common LC fiber active linker shank;
Fig. 2 is the cut-open view of the utility model LC type fiber moveable joint flame retardant plastics stub liner.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Shown in Fig. 1-2, always represent respectively with reference to label: body 1, endoporus 2, reducing 3, cable get into hole 4.
Can be in the finite space for being implemented in the complete distribution cabinet of putting into of common LC fiber active linker; The utility model adopts a kind of soft plastic stub liner than common LC fiber active linker tail pipe short 2/3; Replace the long rigid plastic tail pipe of common usefulness, it is set in crimping place of the capable fiber active linker afterbody of LC, play protection optical cable and LC joint junction; Soft fire proofing can effectively be alleviated outside extruding force simultaneously, reduces the injury to the LC fiber moveable joint.
Referring to Fig. 2, the stub liner described in the present embodiment is its agent structure with body 1, has the inner chamber of cylindrical shape on the body 1, and this cavity is endoporus 2, and this endoporus 2 is afterbody crimping place that are used to be set in the fiber active linker joint.One of body 1 upper shed end is used for joining with connector, and the relative other end inwardly shrinks to form the reducing 3 that an external form roughly is the Rotary-table shape, and this reducing 3 mainly is the buffer action that plays optical cable and tail pipe junction.Reducing 3 ends are provided with a circular cable and get into hole 4, are used for cable and get into the movable flexible jumper of optical fiber.Said cable gets into hole 4 and endoporus 2 coaxial settings.Body 1 and reducing 3 elastic flame plastics thereof are via molded and integrative-structure that constitute; Be that tail pipe adopts single injection-molded specifically; And material selection is soft, elastic force flame retardant plastics preferably; The extruding force that LC fibre-optical splice afterbody receives can be cushioned, the environmental protection and the fire protection requirement of telecommunication apparatus can be met simultaneously.
Adopt the tail pipe of this kind structure, its length is shorter by 2/3 than common LC fiber moveable joint tail pipe, with the LC fiber moveable joint sheathed after, can make LC fiber active linker shank than common with LC type fiber active linker shank length minimizing 1/3.
Claims (4)
1. a LC fiber active linker joint is used stub liner, it is characterized in that: said stub liner comprises that one has the body of cylindrical shape inner chamber, and the outside surface of said body one end inwardly shrinks to form chamfering, and said chamfering outer rim constitutes circular cable and gets into the hole.
2. a kind of LC fiber active linker joint according to claim 1 is used stub liner, it is characterized in that: said body and chamfering thereof are that the elastic flame plastics are via the molded integrative-structure that constitutes.
3. a kind of LC fiber active linker joint according to claim 1 is used stub liner, and it is characterized in that: type roughly is round table-like moulding outside the said chamfered section.
4. a kind of LC fiber active linker joint according to claim 1 is used stub liner, it is characterized in that: said cable gets into hole and the coaxial setting of the cavity of said body.
