Description
Technical field
The utility model relates to a kind of melting cone fiber coupling mechanism.
Background technology
The melting cone fiber coupling mechanism be a kind of can be by specifying splitting ratio carry out the optical passive component that luminous power is distributed, optical fiber in this device adopts the manufacturing of fused biconical taper technology, its coupled section is tiny easily broken, and its splitting ratio is subject to vibrate, the influence of environment temperature and humidity, therefore the encapsulating structure of melting cone fiber coupling mechanism is very crucial, and it directly affects the performance and the life-span of coupling mechanism.Chinese patent ZL200620122557.9 discloses a kind of melting cone fiber coupling mechanism, and its optical fiber is bonded in this quartz ampoule by the epoxide-resin glue at U-shaped quartz ampoule two ends, is set with inside and outside two-layer package tube outside quartz ampoule successively.This melting cone fiber coupling mechanism, the quartz base plate employing U-shaped quartz ampoule because of fixed fiber in the time of in tiny transparent optical fiber being bonded in same transparent quartzy tube seat, is difficult to differentiate the residing particular location of optical fiber, causes visual fatigue easily, the damage eyesight; In addition, when injection is used for fixing silica gel with vibrationproof between quartz ampoule and internal layer package tube and in the narrow and small slit between internal layer package tube and the outer package tube certain degree of difficulty is arranged also, and consuming time longer; Its outer package tube two ends adopt silica gel to seal fully, and the glue accumulating amount is big, and set time is long, influences production efficiency.The part that the melting cone fiber coupling mechanism of this encapsulating structure is adopted is many, viscose glue often, make its packaging technology complexity, production efficiency is on the low side.
The utility model content
The purpose of this utility model provides the melting cone fiber coupling mechanism that a kind of packaging technology is simple, can enhance productivity.
For achieving the above object, the utility model adopts following technical scheme: the melting cone fiber coupling mechanism, comprise melting cone fiber and package tube, the two ends of package tube have hermetically-sealed construction, described package tube inside has quartzy inner panel and quartzy stiffening plate, and the silica gel that quartzy stiffening plate is fixed these plate two ends by bonding in the described hermetically-sealed construction is suspended in the package tube; The xsect of quartzy inner panel and quartzy stiffening plate is semicircular in shape substantially all, and the plate face of two plates is established the length that is shorter in length than quartzy stiffening plate of quartzy inner panel, the bonded middle part of being fixed in quartzy stiffening plate length direction of quartzy inner panel relatively; The coupled section of melting cone fiber places the middle part between described two plates, melting cone fiber is connected and fixed with quartzy inner panel by the adhesive glue point of being located at quartzy inner panel plate face two ends, and melting cone fiber is connected and fixed with quartzy stiffening plate by the adhesive glue point of being located at quartzy stiffening plate plate face two ends.
Described quartzy inner panel plate face width degree is narrower than quartzy stiffening plate plate face width degree, and quartzy inner panel and quartzy stiffening plate centering on Width is arranged.
Adhesive glue point between described melting cone fiber and quartzy inner panel is the optic-solidified adhesive point; Adhesive glue point between melting cone fiber and quartzy stiffening plate is optic-solidified adhesive point and silica gel point; Quartzy inner panel is connected by silica gel and the quartzy stiffening plate bonding of being located at its two ends.
Described hermetically-sealed construction comprises the sealing sheath of inserting in the pore of package tube end that coincide, the central authorities of sealing sheath have hole for injecting glue, melting cone fiber passes from hole for injecting glue, is filled with silica gel in the hole for injecting glue, and this silica gel infiltrates inboard and the package tube inwall and the quartzy stiffening plate end bonding of sealing sheath.
The described sealing sheath outside one end has the sealing convex edge, the end face contact matching of sealing convex edge and package tube tube wall.
Because the utility model adopts the mode of four spot gluings melting cone fiber to be bonded between the plate face of quartzy inner panel and quartzy stiffening plate, both played the effect of strengthening and protecting the melting cone fiber coupled section, when bonding optical fiber, be easy to differentiate the profile of optical fiber again, be convenient to producers and find optical fiber rapidly and accurately accurately, applying glue operation in addition is few, applying glue easy, the point type resin added is short few set time, and this has all improved the production efficiency of coupling mechanism to a certain extent; Semicircular quartzy inner panel and quartzy stiffening plate structure, not only processing technology is good, and the intensity height, can provide better protection to melting cone fiber; The silica gel bonding of the sealed at both ends structure of the quartzy packed pipe of stiffening plate fixedly is suspended in the package tube, makes coupling mechanism have better resistance to shock.
Melting cone fiber and quartzy inner panel and quartzy stiffening plate are united bonding by optic-solidified adhesive and silica gel, promptly with optic-solidified adhesive two bonded bodies are bonded together in advance earlier, solidifying back recycle silicon glue is bondd, because the optic-solidified adhesive curing rate is fast, volumetric contraction is little during curing, and is not acted upon by temperature changes after solidifying, so when producing, existing curing rate faster has cohesive strength preferably again, and especially the temperature stability of coupling mechanism is better.The two ends of package tube adopt sealing sheath to add the form encapsulation that silica gel injects in sheath central authorities, significantly reduced the use amount of silica gel, shortened the set time of two ends silica gel, reduced moisture simultaneously and can invade area, stop the inlet of moisture, improved humidity resistance; When annotating silica gel, silica gel also infiltrates simultaneously in the package tube and is connected with package tube inwall and quartzy stiffening plate bonding, and one time the injecting glue operation is finished a plurality of contents that are bonded and sealed, and technology is simple, operability good; The sealing convex edge is set on the sealing sheath, has stoped moisture, further improve humidity resistance from directly invading sheath and cooperating on the interface of package tube.
