Description
Technical field
The utility model relates to optical communication field more particularly to a kind of optical fiber ceramic lock pins.
Background technique
Optical fiber ceramic lock pin, also known as ceramic contact pin.The cylindrical body of precise centering in optical fiber connector plug, center have one micro-
Hole is used as fixed optical fiber.Optical fiber ceramic lock pin is applied to light jumper, optical connector, optical module in optical communication field etc. and produces
In product.
Status optical fiber ceramic lock pin, such as Fig. 1, having diameter for a cylindrical shape is the structure of 0.125mm micropore 10, micropore
10 one end is equipped with the structure on the portion V 20 or the construction circumference with one or several injecting holes 30, such as Fig. 2, this injecting hole
30 vertical with the micropore 10 of lock pin diameter 0.125mm communicate.
In Fig. 1, the micropore 10 of diameter 0.125mm and the portion V 20 have bubble, and the optical fiber pottery in Fig. 2 with injecting hole 30
Porcelain lock pin, and 10 aperture of lock pin micropore only has 0.125MM, injecting hole 30 in very little (when not half cuts through lock pin hole),
Difficult plastic cement is not easy to inject when injection molding, when injecting hole 30 open it is larger when, optical fiber is not easy in insertion across being easily scraped off.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, and providing one kind does not influence service performance, and is easy to
Fibre is worn, the injecting glue amount in control micropore can be facilitated, not will cause the optical fiber ceramic lock pin that optical fiber is damaged.
The technical solution of the utility model is as follows:
A kind of optical fiber ceramic lock pin, including fiber stub ontology, the inside of the fiber stub ontology through have through-hole and
Optical fiber is inserted into micropore, and the diameter of the through-hole is greater than the diameter of optical fiber insertion micropore, and the through-hole and the optical fiber are inserted into
It is connected between micropore by a V-type mouth, is communicated with an injecting hole for being through to fiber stub ontology top on the V-type mouth.
Further, the diameter of the optical fiber insertion micropore is 0.125mm~0.5mm, and length is less than 3mm.
Further, the length range of the optical fiber insertion micropore is in 0.5~2.5mm.
Further, the diameter range of the through-hole is in 0.25~1.3mm.
Further, the diameter range of the injecting hole is in 0.25~1mm.
Further, the fiber stub ontology is cylindrical.
Compared with the existing technology, the utility model has the beneficial effects that:
The optical fiber insertion microcell length of the optical fiber ceramic lock pin of the utility model, diameter 0.125mm is less than 3mm, and in light
The through-hole of a connection is additionally provided in fine lock pin ontology does not influence service performance after optical fiber is inserted into micropore relative to existing shorten, and
It is easy to wear fibre；V-type mouth between lateral injecting hole and through-hole and optical fiber insertion micropore is connected to, and can be used for controlling injecting glue and row
Gas, when glue amount deficiency, can glue, glue amount is out-of-date to can be used for excessive glue；The product stringent for part control glue, can pass through the injecting hole
Glue is sucked out；Since injecting hole is not cut mutually with optical fiber insertion micropore, it not will cause optical fiber and be damaged.
The utility model can facilitate the injecting glue amount in control optical fiber insertion micropore, can be used for eliminating steam bubble or absorption is extra
Glue.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing cylindric optical fiber ceramic lock pin；
Fig. 2 is the structural schematic diagram of the existing optical fiber ceramic lock pin with injecting hole；
Fig. 3 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 3, the utility model provides a kind of optical fiber ceramic lock pin, including cylindric fiber stub ontology 1, institute
The inside of fiber stub ontology 1 is stated through having through-hole 11 and optical fiber insertion micropore 12, the diameter of the through-hole 11 is greater than described 12
Optical fiber is inserted into the diameter of micropore, is connected between the through-hole 11 and optical fiber insertion micropore 12 by a V-type mouth 13, the V
An injecting hole 14 for being through to 1 top of fiber stub ontology is communicated on type mouth 13.
Wherein, the diameter of optical fiber insertion micropore 12 is 0.125mm~0.5mm, preferably 0.125mm, and length is small
In 3mm.Further, the length range of the optical fiber insertion micropore 12 is in 0.5~2.5mm.
Its optical fiber is inserted into 12 length of micropore less than 3mm, after optical fiber is inserted into micropore 12 relative to existing shorten, does not influence to use
Performance, and be easy to wear fibre；V-type mouth 13 between lateral injecting hole 14 and through-hole 11 and optical fiber insertion micropore 12 is connected to, and can be used
When control injecting glue and exhaust, glue amount deficiency, can glue, glue amount is out-of-date to can be used for excessive glue；The product stringent for part control glue,
Glue can be sucked out by the injecting hole 14；Since injecting hole 14 is not cut with optical fiber insertion 12 phase of micropore, it is impaired optical fiber is not will cause
Wound.
Wherein, the diameter range of the through-hole 11 is in 0.25~1.3mm.
Wherein, the diameter range of the injecting hole 14 is in 0.25~1mm.
In conclusion the utility model can facilitate control optical fiber insertion micropore in injecting glue amount, can be used for eliminating steam bubble or
Absorb extra glue.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
