Abstract
The utility model discloses an optical fiber interface module, comprising a metal fixing base, a metal nut cap, a porcelain bushing and a porcelain lock pin. One end of the porcelain lock pin is fixedin the metal fixing base and the other end is inserted into the porcelain bushing. The porcelain lock pin and the metal fixing base are connected in interference fit. The porcelain bushing is adjustably arranged in the metal fixing base. Both of the two end faces of the porcelain lock pin are tapered planes. The metal nut cap and the metal fixing base are connected in interference fit, with the porcelain bushing closed in the metal fixing base. The patent has the advantages of less optical insertion and return loss, and convenience to insert flexible jumper.
Description
Technical field
The utility model relates to the optical transmission apparatus in a kind of optical fiber communication, particularly relates to a kind of optical fiber interface assembly.
Background technology
The optical fiber interface assembly is to be used for being connected of laser instrument and optical cable optical fiber, and it is the indispensable part of light transmission in the optical communication system, and the optical fiber interface assembly will need the end face of the optical fibre core that connects to aim at, be adjacent to and can repeatedly use repeatedly.Because the core diameter very thin (reaching micron order) of optical fiber, the processing technology of optical fiber interface assembly and precision all have the higher requirement of ratio.
Optical fiber interface assembly in the optical fiber communication industry is the important component part of light transmission at present.As shown in Figure 1, it by ceramic insertion core 1, porcelain bushing 2, metal shell 3, and metal firm banking 4 form, the rear portion of metal firm banking 4 connects with LD light source (laser light source), the endoporus of porcelain bushing 2 is as the centering pilot hole of ceramic insertion core 1 with flexible jumper front end lock pin, ceramic insertion core 1 inserts an end of porcelain bushing 2, and flexible jumper front end lock pin inserts the other end of porcelain bushing 2.The light that laser light source sends is entered by metal firm banking 4 one extreme directions, enter into the optical fiber of ceramic insertion core 1 through ceramic insertion core 1 end face, under the positioning action of porcelain bushing 2, the accurate butt joint of two end faces of optical fiber is got up, go so that the luminous energy of launching fiber output can be coupled in the optical fiber of flexible jumper.
The following shortcoming that traditional this assembly exists:
1, ceramic insertion core 1 is fixed in the porcelain bushing 2, and porcelain bushing 2 can't be movable, can't carry out trickle correction when flexible jumper inserts, thereby may cause the loss of certain luminous energy, thereby increases loss;
Though 2, the ferrule endface of two butt joints all is the plane, can not accomplish that in alignment procedure 100% is seamless, the end face of receiving end can be returned by antireflection part light like this, thereby disturbs transmitting illuminant, causes the data transmission instability;
When 3, flexible jumper front end lock pin inserted porcelain bushing 2, smooth degree was poor.
The utility model content
The purpose of this utility model provides a kind of optical fiber interface assembly, and it is convenient that optical fiber inserts loss and return loss is few, flexible jumper inserts, the smooth degree height.
In order to reach above-mentioned technique effect, the utility model provides following technical scheme: a kind of optical fiber interface assembly, comprise the metal firm banking, metal nut cap, porcelain bushing and ceramic insertion core, ceramic insertion core one end is fixed in the metab, the other end inserts in the porcelain bushing, connect for interference fit between described ceramic insertion core and the metal firm banking, described porcelain bushing is movably arranged in the metal firm banking, described ceramic insertion core two ends end face is tapered plane, described metal nut cap is that interference fit is connected with the metal firm banking, and porcelain bushing is enclosed in the metal firm banking.
Further, described porcelain bushing cross section is " O " font sleeve pipe of remaining silent.
Further, described porcelain bushing is to have groove on the total length, and the cross section is the opening porcelain bushing of " C " font.
Further, an end endoporus of described ceramic insertion core is provided with chamfering.
Further, the employed pottery of described porcelain bushing and ceramic insertion core is zirconia ceramic.
Technique effect of the present utility model is: because ceramic insertion core two ends end face is tapered plane, and the end bore design that porcelain bushing links to each other with flexible jumper has chamfering, the metal firm banking is with after laser instrument links to each other like this, after light sends from laser instrument, through end face is the optical fiber that enters behind the ceramic insertion core of tapered plane in the ceramic insertion core, because porcelain bushing has certain scope of activities in the metal firm banking, can carry out trickle adjustment, under the adjustment location of porcelain bushing, fiber end face in the two butt joint ceramic insertion cores is aimed at, import in the flexible jumper after the luminous energy coupling, thereby realize the connection of light path, make and insert loss and return loss reduction, insert the raising of efficient and smooth degree, thereby promoted the stability and the reliability of optical fiber socket assembly.

Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the structural representation after the utility model assembling.
Embodiment
The utility model is described in further detail for existing accompanying drawings and embodiment:
As Fig. 2, shown in Figure 3, the optical fiber interface assembly of present embodiment mainly comprises: ceramic insertion core 1, porcelain bushing 2, metal firm banking 4, metal nut cap 5, along having the through hole 11 that optical fiber 10 is housed on the axis, ceramic insertion core 1 both ends of the surface are tapered plane in the ceramic insertion core 1.Porcelain bushing 2 and ceramic insertion core 1 all are that zirconia ceramic is made, the endoporus of metal firm banking 4 is column type straight holes, its diameter of bore is more smaller than the external diameter of ceramic insertion core 1, be fixed together with an end interference fit of ceramic insertion core 1, the other end of ceramic insertion core 1 inserts in the porcelain bushing 2, also be inserted with flexible jumper front end lock pin 6 in the porcelain bushing 2, under the location of porcelain bushing 2, optical fiber 11 end faces of optical fiber interface assembly and optical fiber 61 end faces of flexible jumper are aimed at, thereby optical fiber 10 can be aimed at optical fiber 60, for guaranteeing that flexible jumper front end lock pin 6 inserts more easily, is provided with chamfering 20 on the porcelain bushing 2 one end endoporus that link to each other with ceramic insertion core 6.Metal firm banking 4 outer faces couple together by the base 7 of welding and laser instrument 8, thereby realize the connection from laser instrument emissive source 9 to flexible jumper.
