Abstract
The utility model discloses a kind of optical fiber ceramic lock pin, comprise cylindrical ferrule body, the center of described lock pin body is provided with axial circular through hole, and the tail end center of lock pin body is provided with cone-shaped groove, passes through round-corner transition between described cone-shaped groove and described round tube hole.Cone-shaped groove of the present utility model and round tube hole are seamlessly transitted by fillet, there is no dead angle, in injecting glue operation before wearing fibre, can ensure that glue fills up round tube hole completely, and optical fiber can be avoided by disconnected fine when cone-shaped groove and round tube hole junction, improve optical fiber and wear fine success ratio, this ceramic insertion core optical coupling loss is little, connect accurate positioning, easy to use, stable performance, and can greatly improve light signal transmission speed, increase the service life.The utility model is applicable to various ceramic insertion core.
Description
Technical field
The utility model belongs to optical fiber transmission technique field, relates to a kind of optical fiber interface component, is specifically related to a kind of optical fiber ceramic lock pin.
Background technology
Fiber active linker is the centering link in joint, is connected between optical fiber by the split coupling of fiber active linker inside, to ensure the highest switching performance between optical patchcord.Optical fiber ceramic lock pin is the critical component of fiber active linker, it be a kind of by nano zirconia material through a series of formula, the high precision special cermacis element that processes, there is the features such as intensity is high, good corrosion resistance, good insulation preformance, smooth surface, long service life.
The center of ceramic insertion core is provided with axial circular through hole, the tail end center of lock pin body is provided with cone-shaped groove, optical fiber is successively from cone-shaped groove, round tube hole passes through, due in ceramic insertion core process, angle is had between cone-shaped groove cell wall and round tube hole hole wall, in injecting glue operation before wearing fibre, can not ensure that glue is filled in this angle completely, and there is burr in cone-shaped groove and round tube hole junction, optical fiber is through there is disconnected fine risk during this position, optical fiber is disconnected fine in ceramic insertion core, namely ceramic insertion core is scrapped, waste ceramic insertion core manufacturing cost and fiber active linker built-up time.
Utility model content
For solving the above deficiency existed in prior art, the utility model provides a kind of optical fiber ceramic lock pin, cone-shaped groove and round tube hole are seamlessly transitted by fillet, there is no dead angle, in injecting glue operation before wearing fibre, can ensure that glue fills up round tube hole completely, and optical fiber can be avoided by disconnected fine when cone-shaped groove and round tube hole junction, improve optical fiber and wear fine success ratio, this ceramic insertion core optical coupling loss is little, connect accurate positioning, easy to use, stable performance, and can greatly improve light signal transmission speed, increase the service life.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
A kind of optical fiber ceramic lock pin, comprise cylindrical ferrule body, the center of described lock pin body is provided with axial circular through hole, and the tail end center of lock pin body is provided with cone-shaped groove, passes through round-corner transition between described cone-shaped groove and described round tube hole.
As to restriction of the present utility model, described radius of corner is R2.0-2.5.
Limit as to another kind of the present utility model, the central angle of described cone-shaped groove is 60 °.
Owing to have employed technique scheme, compared with prior art, acquired technical progress is the utility model:
Cone-shaped groove of the present utility model and round tube hole are seamlessly transitted by fillet, there is no dead angle, in injecting glue operation before wearing fibre, can ensure that glue fills up round tube hole completely, and optical fiber can be avoided by the fibre that breaks by when cone-shaped groove and round tube hole junction, improve optical fiber and wear fine success ratio, this ceramic insertion core optical coupling loss is little, greatly can improve light signal transmission speed and extend its serviceable life.
In sum, the utility model has the advantages that to connect accurate positioning, easy to use, stable performance.
The utility model is applicable to various ceramic insertion core.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is further described in detail.
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, lock pin body; 2, round tube hole; 3, cone-shaped groove; 4, fillet.
Embodiment
embodiment 1
A kind of optical fiber ceramic lock pin, structure as shown in Figure 1, comprises lock pin body 1.
Lock pin body 1 is in cylindric, and center is provided with axial circular through hole 2, and the head end of lock pin body 1 is step-like structure, and tail end center is provided with cone-shaped groove 3, and the central angle of cone-shaped groove 3 is 60 °.
The center line of round tube hole 2 and the centerline collineation of cone-shaped groove 3, by fillet 4 transition between round tube hole 2 and cone-shaped groove 3, the radius of fillet 4 is 2.5 for the radius of fillet 4 shown in R2.0-2.5(Fig. 1, belongs to preferred version).
The product of the present embodiment is due to cone-shaped groove 3 and the junction transitions smooth of round tube hole 2, there is no dead angle, in injecting glue operation before wearing fibre, can ensure that glue fills up round tube hole 2 completely, and optical fiber is disconnected fine by avoiding during this junction, improve optical fiber and wear fine success ratio, this ceramic insertion core optical coupling loss is little, can greatly improve light signal transmission speed, increase the service life.
