Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing, but is not limited thereto.
The specific embodiment of the caudal peduncle component of optical fiber connector provided by the invention, as shown in Figure 1, Figure 2 and Figure 3, the tail
Handle component includes caudal peduncle 1, and caudal peduncle 1 has the lock pin connecting pin 10 for 2 grafting of ceramic insertion core and with the interference fit of ceramic insertion core 2,
Caudal peduncle 1 is equipped with the optical cable perforation 8 passed through for optical cable, the decreasing pore size of optical cable perforation 8 in its axial direction, and optical cable is worn
Hole 8 its end face at the aperture of ceramic insertion core 2 be oblique 8 degree of faces, for oblique 8 degree of the APC end face on ceramic insertion core 2
9 are fitted close to guarantee that glue will not flow to the side wall of ceramic insertion core 2 during injecting glue.Caudal peduncle component further includes being set to for covering
The glue cap 3 of the one end of caudal peduncle 1 far from lock pin connecting pin 10, glue cap 3 has glue accommodating chamber 5, for realizing the storage of glue
Deposit, seal, and can be mobile when injecting glue and generate injection pressure.In the present embodiment, caudal peduncle 1 is far from ceramic insertion core 2
One end seal groove is equipped at the position of proximal head, be equipped in seal groove for close with the sealing cooperation of the inner wall of glue cap 3
Seal 4.Sealing ring 4 is able to achieve glue cap 3 and is pushing away when stopping with the static seal of the cavity wall of glue accommodating chamber 5 and glue cap 3
With the dynamic sealing of the cavity wall of glue accommodating chamber 5 during pressure, glue in glue accommodating chamber 5 will not be made from caudal peduncle 1 in this way
It is flowed out on lateral surface.
In order to avoid glue cap 3 when not in use by false hit and by glue squeeze out or by external thrust it is larger when be broken,
The retaining piece 6 with the cooperation of the end face block of glue cap 3 is set in the glide direction of the glue cap 3 in caudal peduncle 1.Retaining piece 6 with
Caudal peduncle 1 is integrally formed, during practical injecting glue, due to the small volume of retaining piece 6, and not to the unlimited block of glue cap 3,
Glue cap 3 can cut retaining piece 6 during pushing, in this way glue cap 3 push during not will receive blocking so as to
Smoothly glue is injected in the cable-through hole 11 in ceramic insertion core 2.Caudal peduncle 1 is equipped with gas vent 7 close to the side wall of ceramic insertion core 2,
Surplus glue can be discharged between 0.3mm~0.7mm for the diameter range of the gas vent 7, and guarantee that light is unable to direct irradiation
Glue to inside glue set 3, to not influence the performance of internal glue.In addition, the diameter of the optical fiber in the present embodiment only has
0.125mm, in other embodiments, the internal diameter of cable-through hole 11 can make corresponding adjustment, but corresponding adjustment according to the diameter of optical fiber
The diameter still very little of cable-through hole 11 afterwards, and the aperture of gas vent 7 is also smaller, therefore needs after glue cap 3 completes injecting glue process
When pulling back to take out, glue backflow phenomenon is negligible.The draw speed for properly increasing glue cap 3, can be preferably
Avoid the occurrence of the generation that glue is sucked back into this phenomenon in glue cap 3 again.
Also there are two guide protrusions 13,13 one side of guide protrusions can guarantee caudal peduncle 1 and Fig. 4 into Fig. 7 for tool on caudal peduncle 1
Optical fiber connector main body 12 is adapted in the circumferential；On the other hand, since there is also suitable for ceramic insertion core 2 and optical fiber connector main body 12
With relationship, to guarantee that ceramic insertion core 2 is adapted to optical fiber connector main body 12 indirectly.In the present embodiment, in glue accommodating chamber 5
Glue be UV glue, UV glue rapid curing under ultraviolet irradiation, adhesive strength is high, and fully transparent after solidifying, no
Influence the appearance of optical fiber connector.
It during injecting glue, pushes glue cap 3 to cut retaining piece 6, to release the block to glue cap 3, continues to push away
Dynamic glue cap 3, is injected into the glue in glue accommodating chamber 5 in cable-through hole 11；After the completion of injecting glue, glue cap 3 is extracted, by optical cable
It is inserted into from the optical cable perforation 8 being equipped in caudal peduncle 1, enters the optical fiber of optical cable in cable-through hole 11, then after being heated at high temperature
Solidification.
In the above-described embodiments, caudal peduncle is together with the fixing assembling by the way of ceramic insertion core interference fit, at other
In embodiment, caudal peduncle can also be fixed with ceramic insertion core by other means, such as the caudal peduncle of injection molding can be used.
In the above-described embodiments, a gas vent is provided on the lateral wall of caudal peduncle extra glue is discharged, and arranged
The aperture of stomata is 0.5mm, in other embodiments, can be according to factors such as type, the viscosity of glue, the quantity of gas vent and straight
Diameter can do corresponding adjustment；Certainly, the glue of glue accommodating chamber just when can also be not provided with gas vent.
In the above-described embodiments, it is sealed and is cooperated by sealing ring between glue set and caudal peduncle, it in other embodiments, can also
It is to realize sealing in a manner of using others.For example, land is arranged on caudal peduncle outer peripheral surface, it is interference fitted with the inner wall of glue cap
Realize sealing.
In the above-described embodiments, by the lateral surface of caudal peduncle be arranged retaining piece come avoid glue cap when not in use by
False hit can also avoid in other way glue cap when not in use by false hit in other embodiments.Example
Such as, it can be not provided with retaining piece, covered when not in use in glue, worn a positioning pin on glue set and glue set is fixed on caudal peduncle
On, prevent it by false hit；When needing to inject glue, positioning pin is taken out, to can manually push glue set；It for another example, can be
The buckle of a U-shaped is set between the end face and caudal peduncle of glue cap.
The specific embodiment of optical fiber connector provided by the invention: as shown in Figure 4, Figure 5, Figure 6 and Figure 7, optical fiber connector
Including for ceramic insertion core 2 wherein one end connection optical fiber connector main body 12, ceramic insertion core 2 and for ceramic insertion core 2 far from light
