Abstract
The utility model relates to an optical fiber adapter interface, including a housing with a plug socket and a connection tube fixed in the housing, the connection tube is formed through buttjunction of two pipe fittings, a reed is of crimp connection between each pipe fitting and opposite inner wall of the housing, two ends of the pipe fitting are provided with one elastic press jacket respectively, the pipe fitting is provided with a locating hook facing to the plug socket, the side wall of the locating hook is provided with a groove, and the groove is matched with a projection arranged on the middle of the reed. The utility model overcomes defects that the connection tube is easy to break in a process of manufacturing a common optical fiber adapter interface, rate of finished products is low and whole fabrication cost is high, according to the utility model, when an optical fiber connector is inserted from two heads of the optical fiber adapter interface, optical fiber pins can be located accurately and coaxially. The utility model has advantages of simple structure, easy installation, nonbreakable, strong universality and low cost of manufacture.
Description
Technical field
The utility model relates to a kind of fiber adapter interface.
Background technology
The Primary Component that is used for ferrule of optical fiber connector insertion location in the existing fiber adaptor interface is a splicing sleeve, splicing sleeve is generally ceramic pipe, one side of pottery pipe is opened groove, utilize positioning pipe endoporus and optical fiber contact pins diameter interference fit, and, realize the optical fiber contact pins coaxial positioning of two insertions owing to a side is opened the elasticity pressure folder power that groove produces the tube wall distending.But because the positioning pipe that adopts ceramic raw material to make is big because of investment of production equipment, high-precision rounding difficulty of processing is big, and again because of ceramic pipe belongs to the fragility body, tube wall approach (the about 0.35mm of wall thickness) cracky in manufacture process, the low and increase production cost of yield rate.
Summary of the invention
For overcoming the above-mentioned problem of prior art, the utility model provides a kind of fiber adapter interface, this fiber adapter interface simple in structure, easy for installation, and the optical fiber contact pins coaxial alignment of cracky, two insertions is inaccurate, highly versatile.
The technical scheme that its technical matters that solves the utility model adopts is: comprise the housing of carrying spigots and be fixed on the interior splicing sleeve of housing, butt joint constitutes splicing sleeve to clamp spare by two, to crimping reed between clamp spare and the relative inner walls, clamp spare two respectively is provided with an elasticity presses the chuck circle.
To being provided with the positioning hanger relative on the clamp spare, on the sidewall of positioning hanger with socket
Groove is set, and groove matches with projection on the reed middle part.
On housing, be provided with the connection positioning cards.
At the positioning bar that the sidepiece setting to clamp spare fuses, positioning bar matches with locating slot on the inner walls.
The utility model is by above-mentioned specific design, and when two of fiber adapter interface inserted, optical fiber contact pins is coaxial alignment accurately at the joints of optical fibre, have simple in structure, use is easy to operate, reliability is high, highly versatile, advantage with low cost.

Embodiment
As shown in the figure, the utility model comprises the housing 1 and the splicing sleeve that is fixed in the housing 1, a side close-fitting cover plate 9 of housing 1 in the present embodiment of carrying spigots 2.3 butt joints constitute splicing sleeve to clamp spare by two, to locating by detent mechanism between the clamp spare 3, clamp spare 3 is adopted high strength, the thermosets of high-wear resistance or metal material are made, the cross section of the location endoporus that clamp spare 3 is formed of butt joint be a circle, polygons etc. are suitable for the fit shapes of grip optical fibers contact pin 14, the inwall of location endoporus also can be provided with positioning bar to strengthen the locating effect to optical fiber contact pins 14, at the positioning bar 10 that the sidepiece setting to clamp spare 3 fuses, positioning bar 10 matches with locating slot 11 on housing 1 inwall and cover plate 9 inwalls respectively.To crimping reed 4 between clamp spare 3 and relative housing 1 inwall, two to clamp spare 3 respectively is provided with an elasticity pressure chuck circle 12, be provided with the positioning hanger 5 relative on to clamp spare 3 with socket 2, positioning hanger 5 with can fuse to clamp spare 3, groove 6 is set on the sidewall of positioning hanger 5, and groove 6 matches with projection 7 on reed 4 middle parts.At reed 4 with suppress under the effect of chuck circle 12, two form the folder power of pressing when clamp spare 3 closed up, when the joints of optical fibre 12 when two fiber adapter interfaces insert, contact pin 13 and two location endoporus interference fit of clamp spare 3 being closed up formation, realize accurate coaxial alignment, simultaneously because positioning hanger 5 is hung tight two joints of optical fibre 13, the end face that makes relative optical fiber contact pins 14 near.The effect of the connection positioning cards 8 that is provided with on housing 1 is to make the fiber adapter interface be fit to be installed on the panel.Above-described embodiment only is that the preferred implementation to the utility model fiber adapter interface is described; be not that design and scope to utility model limits; under the prerequisite that does not break away from the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model all should fall into the protection domain of the utility model fiber adapter interface.
