Description
Technical field
What optical fiber clamping alignment device of the present invention related to is a kind of gordian technique device of optical fiber quick connector, is the core passive block in order to the assembling optical fiber quick coupler.
Background technology
Along with fiber-to-the-home extensive enforcement, optical fiber quick connector has become broadband access and has built requisite a kind of optical device, and the market demand is very huge.The existing fiber quick coupler still exists some key issues that solution is not arranged in use at present.
Pre-buried fiber type optical fiber quick connector coupling end face adopts factory level to grind, and the return loss index is reliably guaranteed, can obtain the return loss of the high reliability of fiber active linker level.But should technology how to realize that aligning, the clamping of optical fiber became its core key technology; How realizing importing fibre docks, how to realize importing fine safe clamping with the reliable of pre-buried fibre; Mode is also all different, has at present that factory-assembled or execute-in-place success ratio are not high, operation inconvenience, the multiple kit of needs carries out defective and deficiencies such as compounding practice; More of paramount importance problem is; Because so use of enormous quantity optical fiber quick connector; Owing to adopted pre-buried fibre to adopt optical fiber coupling cream; Caused the worry that this auxiliary material life problems is caused optical fiber quick connector tenure of use or reliability; In case the optical fibre refractivity that adopts coupling cream quality problems or because environmental impact causes coupling cream to lose efficacy will have influence on the huge optical fiber quick connector of quantity and use are for Cybersecurity Operation and later maintenance bring anxiety and non-reliable guarantee.
Summary of the invention
The present invention seeks to provides a kind of optical fiber clamping alignment device to above-mentioned weak point; Optical fiber clamping aligning members is that a kind of optical fiber quick connector optical passive component of brand new is produced used core component; Optical fiber quick connector has been possessed can be repeated, and can repair, maintainable multiple function; Realize that optical fibre refractivity matees cream and repeatedly safeguards filling, eliminate the worry of optical fiber quick connector because of the probable life of matching materials initiation.
Optical fiber clamping alignment device takes following technical scheme to realize:
Optical fiber clamping alignment device comprises that ceramic insertion core, pre-buried optical fiber, integrated of V groove butt joint, clamping crimp, gradual change footpath optical fiber import part and optical fiber clamping opening tool.Pre-buried optical fiber dress is inserted in the ceramic core; Wire jumper level grinding in the factory is carried out in ceramic insertion core one side end face; The ceramic insertion core opposite side is fixed on integrated front end of V groove butt joint; Integrated rear end of V groove butt joint inserted gradual change footpath optical fiber and imported part, and movable mode can realize the inter-module replacing, is convenient to increase operation rate and assembling flexibly; The clamping crimp docks integrated and forms the snap-lock locking structure with the V groove, and can repeat; Optical fiber clamping opening tool is used for the clamping crimp and realizes the crimping of repetition optical fiber with separating of integrated of V groove butt joint, as convenient carrying of widget.The clamping crimp can dock integrated with the V groove separated and take off, and the optical fibre refractivity that is used to annotate coupling cream realizes that optical fibre refractivity matees cream and repeatedly safeguards filling, eliminates the worry of optical fiber quick connector because of the probable life of matching materials initiation.Integrated of said V groove butt joint is provided with V-shaped groove, the optical fiber of can annotating in V-shaped groove coupling cream.
Principle of work
Optical fiber clamping alignment device principle is: pre-buried optical fiber inserts the ceramic insertion core injecting glue and solidifies back one end grinding, and after other end fixed length cutting was handled, gluing was fixed in integrated one side of V groove butt joint, carries out secondary baker cured, the optical fiber of can annotating in V groove coupling cream; Gradual change footpath optical fiber imports part and inserts integrated opposite side of V groove butt joint.The corresponding buckle clamping of integrated groove of V groove butt joint crimp, block button hole adopts the design of throwing face italic, realizes strengthening elasticity and the tight ness rating that buckle is fitted; The design of packaging type cavity body structure, the sealing that has promoted clamping and aimed at node are taked in integrated of V groove butt joint.
When needs imported on-site cutting optical fiber, it was relative separation that the clamping crimp docks integrated with the V groove, and optical fiber is pressed the crimping that completion imports optical fiber with the clamping crimp after importing the part importing through gradual change footpath optical fiber.Optical fiber imports part and adopts gradual change directly to design, and realizes the automatic straightening of fiber alignment.
When repeating to open, use optical fiber clamping opening tool by integrated inside jack-up in bottom of V groove butt joint, can realize that the clamping crimp docks integrated separating with the V groove, this moment, the importing optical fiber of on-site cutting can be detached by optical fiber clamping aligning members.
When mating cream and annotate again; Dock with the V groove at above-mentioned clamping crimp under integrated the released state; Adopt metal pincet commonly used can the clamping crimp be taken off fully; Integrated interior V groove of V groove butt joint this moment reveals to do well and can mate the cream filling, after having operated, the clamping crimp can be accomplished the high filling of coupling attended operation on the mouth once more.
Optical fiber clamping alignment device is that a kind of optical fiber quick connector optical passive component of brand new is produced used core component; Optical fiber quick connector has been possessed can be repeated; Can repair; Maintainable triple functions has solved in the industry the worry that coupling cream actual effect can't defuelling be safeguarded, this product has following characteristics:
1. optical fiber clamping alignment device adopts on-site cutting optical fiber to import and pre-buried fine V groove separate design, realizes repairing of production and assembly, practices thrift assembly loose mail cost and workshop efficiency of assembling.
2. optical fiber clamping alignment device adopts brand-new unique buckle-type crimping clamping technology, and the integrated design of packaging type cavity is adopted in pre-buried, V groove, butt joint, promotes the sealing of core node.
3. optical fiber clamping aligning members on-site cutting optical fiber imports and adopts gradual change directly to design, self-correcting collimation butt joint when realizing the importing of execute-in-place optical fiber.
4. in the V groove of optical fiber clamping alignment device docks integrated; Importing on-site cutting optical fiber one end, butt joint bare fibre (peeled off coat or tight sleeve layer after importing optical fiber) carries out efficient and the accuracy rate that secondary calibration leading-in technique in the V groove ensures fiber alignment.
5. optical fiber clamping alignment device is implemented in site of deployment and fast optical fiber quick connector is carried out the filling of optical fibre refractivity coupling cream immediately and safeguard, on-site cutting is imported optical fiber, pre-buried optical fiber, optical cable clamping have no effect.
This invention optical fiber clamping alignment device is realized annotating of optical fibre refractivity coupling cream, but makes optical fiber quick connector possess maintenance function; Adopt packaging type cavity new construction, promoted the sealing of key nodes such as pre-buried, V groove, butt joint; Adopt buckle-type crimp design structure, need not speciality tool and can accomplish the compactedness that repeats to open and keep fitting.This invention optical fiber clamping alignment device is a kind of brand-new optical fiber clamping align structures.
