Abstract
The utility model relates to a special-purpose connector for the connection of the optical fibers, which is the improvement of the traditional connector. One scheme is to adopt the sliding sleeve barrel method, comprising a boss connector used for connecting the end of the optical fiber and a sleeve barrel. The boss connector is sheathed in the central hole of the sleeve barrel, and the boss is matched with the inner end surface of the sleeve barrel. The sleeve barrel is provided with inner screw-threads connected with other members. The other scheme is to adopt a positive and reverse buckling inner screw-thread sleeve barrel, and the screw-threads on both ends are respectively connected with the optical fiber and other members. Using the special-purpose connector can ensure the optical fiber does not rotate when installed or removed to avoid damaging the expensive optical fiber.
Description
The utility model relates to a kind of optical fiber junction, belongs to the coupling machinery coupling arrangement technical field of optical waveguide and photovalve.
Optical fiber junction, comprise being connected of light transmitting fiber and probe (lighting device) and being connected of light transmitting fiber and detector (sensor), usually adopt and be threaded into or standard DIN formula joint, these two kinds of joints all make light transmitting fiber rotate easily and cause quartz glass fibre to damage, because light transmitting fiber generally is used for accurate light conduction occasion, even partly damage and also can bring very big influence to use, it is overproof for example to make the optical fiber width of cloth penetrate the precise decreasing of thermometer.
The purpose of this utility model is to disclose a kind of improved optical fiber junction, and light transmitting fiber is connected with miscellaneous part under the situation of not rotating.
This light transmitting fiber not rotary type jointing comprises two kinds of forms according to fibre-optic common use occasion: a kind of is the sliding sleeve connected mode, and another kind is positive and negative retaining ring tube connected mode.
Optical fiber junction is made up of the boss joint and the muff joint that are connected with light transmitting fiber in first kind of technical scheme, the boss fitting sleeve is loaded on the center pit of muff joint, movingly, the inner face of its boss platform and sleeve connects, sleeve is provided with the internal thread that is connected with other elements, and the boss joint can adopt fixed or thread connecting mode is connected with the light transmitting fiber end.
Optical fiber junction is a sleeve that is provided with positive left-hand thread internal thread in second kind of technical scheme, and its threaded one end is used for connecting with the light transmitting fiber end, and other end screw thread is used for connecting with other elements.
Adopt when any end of optical fiber is connected with lighting device or sensor behind the above-mentioned special joint,, optical fiber itself is not rotated and do not increase the attended operation difficulty no matter be dress or tear open.Described two kinds of different structure special joints also have universality.
With regard to drawings and Examples the utility model is specified below.
Fig. 1 is a kind of sliding sleeve joint design synoptic diagram that light transmitting fiber is connected with lighting device.
Fig. 2 is a kind of positive and negative retaining ring socket joint header structure synoptic diagram that light transmitting fiber is connected with sensor.
Fig. 3 is a kind of not isometrical positive and negative retaining ring socket joint head.
The housing bright dipping end of lighting device 1 is provided with external thread among Fig. 1, the centre is a lens sleeve 5, be threaded with the lighting device housing, be used for regulating the distance between lens and the optical fiber light inputting end, special joint is by adopting device sleeve 2 and optical fiber boss joint 3 to form, and optical fiber boss joint 3 is set in the center pit of lighting device sleeve 2, connects movingly, the light inputting end of optical fiber boss joint 3 is provided with protruding 6, cooperates with the inner face of lighting device sleeve 2; Lighting device sleeve 2 is provided with internal thread, is used for being connected with lighting device 1, and optical fiber boss joint 3 also is provided with internal thread, is used for being connected with optical fiber 4.
Earlier optical fiber 4 is passed the center pit of lighting device sleeve 2 during use, screw in again in the optical fiber boss joint 3, and then lighting device sleeve 2 and lighting device 1 are spun.During on-the-spot the use since lighting device usually be fixed on the equipment, so optical fiber is not rotated when adopting this connected mode to guarantee to install and remove.
Sensor 11(generally is located in the casing among Fig. 2) through a biography light pipe 12 the light inlet link is leant out outside the machine shell panel 15, biography light pipe 12 is generally STRTHD with sensor 11 and is connected.Also be connected passing between light pipe 12 and the optical fiber 14 through a sleeve 13, sleeve 13 is provided with positive left-hand thread internal thread, be connected with optical fiber 14 and biography light pipe 12 respectively, general maintenance optical fiber 14 is right-handed thread, so be threaded for left-hand thread between sleeve 13 and the spiral light pipe 12, pass light pipe 12 light inputting ends and also be provided with clamp nut 16, make biography light pipe 12 fixedly connected the cylindrical annular knurl of sleeve 13 with panel 15.
To pass during use light pipe 12, sleeve 13 and light transmitting fiber 14 threes align the back turnbarrel 13 can realize not being rotationally connected of optical fiber 14.
Two exemplary embodiments of narration special joint can directly be fixedlyed connected with optical fiber end at the first routine situation lower convex platform joint 3 above.Also can adopt not isometrical positive and negative retaining ring socket joint head in addition, the realization lighting device is connected with optical fiber, as shown in Figure 3, the small-caliber end of not isometrical sleeve 20 is provided with the internal thread that is connected with light transmitting fiber 21 ends among the figure, big mouthful is provided with the lighting device for example with other elements 22(through end) internal thread that is connected, two kinds of internal threads are positive left-hand thread screw thread.
