Abstract
The utility model relates to a hot-melt type optical fiber movable connector, which comprises a ceramic pin component, an optical cable clamping nut, a thermal shrinkage protection sleeve and a spring, wherein a rubber-insulated wire optical cable penetrates through the optical cable clamping nut, the thermal shrinkage protection sleeve and the spring; the thermal shrinkage protection sleeve is heated and shrunk, enters a buffer area and is welded with a preset optical fiber in the ceramic pin component through an optical fiber fusion splicer; and an inner sheath and a dustproof shell are assembled. Because a coating from a metal tail handle of the ceramic pin component to the rubber-insulated wire optical cable is arranged in an area protected by the optical fiber thermal shrinkage protection sleeve, the coating layer of the rubber-insulated wire optical cable with the length of about 11-12mm serve as retraction buffer of the ceramic pin, and the pressure on the end face of the ceramic pin can be kept in a specified range in a using state, so that the reliability and stability of the product are guaranteed.
Description
Technical field
The utility model relates to a kind of joints of optical fibre, and the activity of particularly a kind of heat molten type optical fiber connects device.
Background technology
Along with fiber-to-the-home extensive popularizing, the joints of optical fibre have obtained being widely used.Compare with mechanical type, the joints of optical fibre have higher reliability and stability.Existing optical fiber quick connector adopts the ceramic contact pin assembly of prefabricated band optical fiber, protects through the weld of thermal shrinkage protective casing with covered wire cable and preformed fibers, assembles.Under user mode, the end face of two joints of optical fibre is an interference fit, and the ceramic contact pin end face contracts after the meeting.Because the pyrocondensation protective casing all is fixed together ceramic contact pin assembly and covered wire cable; The buffer area of contracting after reserving; Cause the contact pressure of fiber end face excessive (communication industry standard requires pressure between 2.0-5.9N); Directly influence the insertion loss and the return loss of the joints of optical fibre, and influence connect-disconnect life.
Summary of the invention
The purpose of the utility model is in order to overcome the excessive problem of ceramic contact pin end force of existing fiber connector.
The purpose of the utility model realizes as follows: the activity of heat molten type optical fiber connects device, comprises ceramic contact pin assembly, optical cable binding nut, pyrocondensation protective casing, spring composition.Covered wire cable is passed optical cable binding nut, pyrocondensation protective casing, spring, heating of pyrocondensation protective casing and deflation, the optical fiber that presets that gets in buffer zone and the ceramic contact pin assembly is welded together with optical fiber splicer, and inner sheath and dust cover assemble completion.Because the zone in the protection of optical fiber pyrocondensation protective casing is the coat of metal caudal peduncle to the covered wire cable of contact pin assembly; The buffering that the coat optical fiber of covered wire cable of 11-12mm of having an appointment contracts after as ceramic contact pin; Under the user mode; The pressure that can guarantee the ceramic contact pin end face in the scope of regulation, thereby guaranteed reliability of products and stability.
Said optical cable binding nut is the device that is used for fixing optical cable, and the optical cable after guaranteeing to fix can not exert an influence to the accuracy of alignment of optical fiber when the pulling force that is allowed.
Said ceramic contact pin assembly is the standardized element that cooperates with standard adapter, uses hardening agent can pre-buried optical fiber be fixed in the ceramic contact pin assembly, to exposing outside needs through grinding and polishing.
Said inner sheath and dust cover are the fiber adapter mating parts of standard, in this product, play the effect of protection optical fiber.
The good effect of the utility model is following: the activity of said heat molten type optical fiber connects the device structure, and is reusable, and utilization factor is high, and it is safeguarded and be easy to detect, makes practical operation simpler, and assembling process only needs two minutes, has improved work efficiency greatly.
Description of drawings
Fig. 1 is the utility model decomposition texture synoptic diagram;
Fig. 2 is the section of structure (after the assembling completion) of the utility model;
Fig. 3 is the section of structure (under the user mode) of the utility model;
Among the figure, 1 dust cover, 2 inner sheaths, 3 ceramic contact pin assemblies, 4 springs, 5 pyrocondensation protective casings, 6 back seats, 7 optical cable binding nuts.
Embodiment
Shown in Figure 3 like Fig. 1 Fig. 2, the activity of said heat molten type optical fiber connects device, comprises dust cover 1, inner sheath 2, ceramic contact pin assembly 3, spring 4, pyrocondensation protective casing 5, back seat 6, optical cable binding nut 7 compositions.Covered wire cable is passed optical cable binding nut 7, pyrocondensation protective casing 5, spring 4; 5 heating of pyrocondensation protective casing and deflation; The optical fiber that presets that gets in buffer zone and the ceramic contact pin assembly 3 is welded together with optical fiber splicer, assembles completion to inner sheath 2 and dust cover 1.Because the zone in 5 protections of optical fiber pyrocondensation protective casing is the coat of metal caudal peduncle to the covered wire cable of contact pin assembly; The buffering that the coat optical fiber of covered wire cable of 11-12mm of having an appointment contracts after as ceramic contact pin; Under the user mode; The pressure that can guarantee the ceramic contact pin end face in the scope of regulation, thereby guaranteed reliability of products and stability.
Said optical cable binding nut 7 is the devices that are used for fixing optical cable, and the optical cable after guaranteeing to fix can not exert an influence to the accuracy of alignment of optical fiber when the pulling force that is allowed.
Said inner sheath 2 is the fiber adapter mating parts of standard with dust cover 1, in this product, plays the effect of protection optical fiber.
Said ceramic contact pin assembly 3 is the standardized elements that cooperate with standard adapter, uses hardening agent can pre-buried optical fiber be fixed in the ceramic contact pin assembly 3, to exposing outside needs through grinding and polishing.
Said back seat 6 is the influences that do not receive external force behind the protection optical cable baring.
During site operation; With stripping fiber optic cables directly penetrate with the ceramic contact pin assembly in the optical fiber that presets be welded together with optical fiber splicer, the adjustment optical fiber microbend, with the finger optical cable is clamped; Clamp optical cable on the spiro cap simultaneously and screw, putting inner sheath and dust cover can accomplish.
Above-described practical implementation only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle; Also can do some adjustment and improvement, these also should be regarded as belonging to the protection domain of the utility model.
