Abstract
The utility model discloses a ferrule of a pre-buried optical fiber quick connector. A core hole which stretches along a direction of length is arranged inside a ceramic body, a hole diameter of the core hole is the same as a diameter of a bare optic fiber, and an adding groove of matching paste is arranged on the ceramic body. By means of the ferrule of the pre-buried optical fiber quick connector, accurate connecting of an optic fiber on the scene and a prefabricated optic fiber can be achieved, a connected optic fiber can be guaranteed to be non-shifted, non-deformed and non-broken, and therefore reliability of connecting of optic fibers is improved.
Description
Technical field
The utility model belongs to optical fiber interconnection technique field, relates in particular to a kind of pre-buried type optical fiber quick connector.
Background technology
The assembled on site fiber active linker is optical fiber quick connector again, and being meant in the optical fiber working-yard does not need heat sealing machine, only through simple tool for connecting, utilize MACHINERY JOINT realize the registering one's residence mode of the direct Cheng Duan of optical cable.Need not injecting glue, grinding in the field-installed process of connector.Be divided into by its inner structure on the existing market: assembled on site presets fiber active linker and non-two kinds of the fiber active linkers that preset of assembled on site.
Assembled on site presets the fiber active linker abbreviation and presets the joints of optical fibre; It is presetting the optical fiber that joints of optical fibre head ceramic insertion core inside penetrates a certain-length and ground, the optical fiber of construction optical cable with preset optical fiber through aim at contact and at the contact point place interpolation mate cream.Thereby reach the logical light characteristic of optical fiber.
As everyone knows, be rectilinear propagation during the spread fiber light signal.Can both cause the spread fiber loss to strengthen if any bending or optical fiber are injured.Even can cause the situation of obstructed light to take place.And the ceramic insertion core of pre-buried type optical fiber quick connector says simply be exactly that two optical fiber are accurately aimed at connection.But the alignment so that adopts on our the present market mostly is the aligning of V-type slot type.
As depicted in figs. 1 and 2, because V-type slotted vane 11 can only guarantee to 3 directions of naked fine 13 stressed with cover plate 12 clampings.When the joints of optical fibre are preset in installation, when just penetrating field optical fibers.Cover plate is an open mode, can not guarantee that optical fiber can be close to the V-type slotted vane and penetrate into.Artificial when pressing down cover plate, possibly cause field optical fibers off normal or optical fiber injured, thereby can not guarantee field optical fibers can not with preset optical fiber and fit tightly and contact.And the V-type slotted vane is adopted often all is metal material be made (plastics easy deformation).But metal material can produce under high low temperature condition and expand with heat and contract with cold.Thereby cause the optical fiber obstructed light that fractures.
The utility model content
For this reason; The utility model technical matters to be solved provides a kind of ceramic insertion core of pre-buried type optical fiber quick connector; This ceramic insertion core can be realized the accurate butt-joint of field optical fibers and preformed fibers; And can guarantee after the butt joint optical fiber not off normal, indeformable, do not fracture, thereby improve the reliability that optical fiber connects, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of ceramic insertion core of pre-buried type optical fiber quick connector is characterized in that: have the core hole of extending along its length in ceramic main body inside, the aperture in said core hole is consistent with the diameter of naked fibre, and the said coupling cream that on ceramic main body, offers adds groove.
In the utility model embodiment, said coupling cream adds the middle part that groove is positioned at ceramic main body.Said ceramic main body is a right cylinder.
Adopt technique scheme and since pottery have non-conductive property and do not catch a cold hot, therefore, can be so that the optical fiber in it receive extraneous thermal effect with pottery, and itself can not be out of shape and cause optical fiber to fracture as ferrule body; In ceramic main body, directly adopt in addition with naked fibre with the core hole in footpath as slot; Help to improve the concentricity that field optical fibers is connected with preformed fibers like this; Concentricity can arrive below the 0.5um, and the fiber active linker index loss of making can reach below the 0.2dB; And optical fiber does not receive external force clamping, in the raw, can guarantee the reliability that optical fiber connects.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the alignment so synoptic diagram of V-type slot type of the pre-buried type optical fiber quick connector of prior art;
Fig. 2 is that the V-shaped groove among Fig. 1 cooperates synoptic diagram with cover plate;
Fig. 3 is the structural representation of the utility model.
Among the figure:
11-V shape slotted vane, the 12-cover plate, the naked fibre of 13-, the 100-ceramic main body, 200-core hole, 300-coupling cream adds groove.
Embodiment
As shown in Figure 3, the ceramic insertion core of the pre-buried type optical fiber quick connector of the utility model comprises ceramic main body 100, and this ceramic main body 100 is a cylindrical structure, and its inside has the core hole 200 of extending along its length.The aperture in this core hole 200 is consistent with the diameter of optical fiber.Offer coupling cream at ceramic main body 100 middle parts and add groove 300, add groove 300, can in ceramic insertion core, add coupling cream and add groove through this coupling cream.
Adopt said structure, the utility model since pottery have non-conductive property and do not catch a cold hot, therefore, can be so that the optical fiber in it receive extraneous thermal effect with pottery, and itself can not be out of shape and cause optical fiber to fracture as ferrule body; In ceramic main body, directly adopt in addition with naked fibre with the core hole in footpath as slot; Help to improve the concentricity that field optical fibers is connected with preformed fibers like this; Concentricity can arrive below the 0.5um, and the fiber active linker index loss of making can reach below the 0.2dB; And optical fiber does not receive external force clamping, in the raw, can guarantee the reliability that optical fiber connects.
Therefore, the utility model has been realized the accurate butt-joint of field optical fibers and preformed fibers, and guaranteed after the butt joint optical fiber not off normal, indeformable, do not fracture, improved the reliability that optical fiber connects.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model, as long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
