Abstract
The utility model relates to the technical field of fiber connectors, and specifically relates to an LC fiber connector. The LC fiber connector comprises a front shell, a rear shell, a PVC tube, a spring, an insertion core, a tail sheath and a stainless steel compression ring, the tail end of the rear shell is provided with a metal tube for compressing a fiber sheath and aramid, and the stainless steel compression ring is connected with the metal tube in a compression manner. The LC fiber connector no longer employs a conventional heat-shrinkable bushing, but the fiber sheath and aramid are compressed via the metal tube by taking advantage of the stainless steel compression ring, the compaction force of the stainless steel compression ring is larger than the compaction force of the heat-shrinkable bushing, and the friction between the metal tube and the fiber sheath is increased so that larger stretching resistance can be provided, and the requirement of the stretching resistance of 70 N for the current industry standard is satisfied.
Description
Technical field
The utility model relates to joints of optical fibre technical field, relates in particular to a kind of LC joints of optical fibre.
Background technology
The LC joints of optical fibre are because physical dimension is little, occupy little space, use density is large, be widely used in various optical fiber wiring systems, traditional LC joints of optical fibre are generally by fore shell, back cover and be arranged on fore shell and back cover in pvc pipe, spring, lock pin, heat-shrinkable T bush, pressure ring, the loose mails such as tail sheath assemble, wherein, heat-shrinkable T bush and pressure ring are an integral body, loose mail is when assembling, aramid fiber in pressure ring locking optical fiber, the crust of heat-shrinkable T bush fixed fiber, this traditional structure is difficult to meet the requirement that current industry standard is 70N about stretching resistance, have much room for improvement.
The utility model content
The purpose of this utility model is to provide a kind of stretching resistance to meet 70N, meets the LC joints of optical fibre of current industry standard-required.
The utility model is achieved in that a kind of LC joints of optical fibre, comprise fore shell, back cover, pvc pipe, spring, lock pin and tail sheath, also comprise the stainless steel pressure ring, described back cover tail end is provided with the metal tube for pressed fiber crust and aramid fiber, described stainless steel pressure ring and described metal tube crimping.
Wherein, at least be provided with the crimp groove of twice for pressed fiber aramid fiber and crust on described metal tube.
Wherein, the length of described stainless steel pressure ring is greater than the length of described metal tube, the direct pressed fiber crust of described stainless steel pressure ring afterbody and aramid fiber.
Wherein, described tail length is 12mm.
Wherein, the total length of the described LC joints of optical fibre is 35mm.
Wherein, described pvc pipe length is 10mm.
The beneficial effects of the utility model are: the LC joints of optical fibre described in the utility model do not re-use traditional heat-shrinkable T bush, but utilize the stainless steel pressure ring by crust and the aramid fiber of metal tube pressed fiber, the snap-in force of described stainless steel pressure ring is greater than the snap-in force of heat-shrinkable T bush, friction force between metal tube and optical cable coating increases, so larger stretching resistance can be provided, meet the requirement that current industry standard is 70N about stretching resistance.

Wherein, 1, fore shell; 2, back cover; 21, metal tube; 22, crimp groove; 3, pvc pipe; 4, spring; 5, lock pin; 6, tail sheath; 7, stainless steel pressure ring; 8, optical fiber; 81, crust and aramid fiber; 9, dust cap.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
Embodiment as the LC joints of optical fibre described in the utility model, as shown in Figures 1 to 4, comprise fore shell 1, back cover 2, pvc pipe 3, spring 4, lock pin 5 and tail sheath 6, also comprise stainless steel pressure ring 7, described back cover 2 tail ends are provided with for the crust of pressed fiber 8 and the metal tube 21 of aramid fiber 81, described stainless steel pressure ring 7 and described metal tube 21 crimping.
The LC joints of optical fibre described in the utility model do not re-use traditional heat-shrinkable T bush, but utilize stainless steel pressure ring 7 by crust and the aramid fiber 81 of metal tube 21 pressed fibers 8, the snap-in force of described stainless steel pressure ring 7 is greater than the snap-in force of heat-shrinkable T bush, friction force between metal tube 21 and optical cable coating increases, so larger stretching resistance can be provided, meet the requirement that current industry standard is 70N about stretching resistance.
In the present embodiment, at least be provided with the crimp groove 22 of twice for pressed fiber aramid fiber and crust 81 on described metal tube 21, after stainless steel pressure ring 7 compresses metal tube 21, can increase the friction force between metal tube 21 and optical cable coating, thereby can better lock optical fiber, further improve the stretching resistance of the LC joints of optical fibre.
In the present embodiment, the length of described stainless steel pressure ring 7 is greater than the length of described metal tube 21, and described stainless steel pressure ring 7 afterbodys are pressed fiber crust and aramid fiber 81 directly, thereby increases the friction force between back cover 2 and optical fiber 8.
In the LC joints of optical fibre, the Main Function of tail sheath is the crimping structure of parcel afterbody, in traditional LC joints of optical fibre because heat-shrinkable T bush length is longer, cause the length of tail sheath also longer, be generally 27mm, because the utility model no longer adopts heat-shrinkable T bush, and the length of stainless steel pressure ring 7 is shorter, the length of tail sheath 6 is foreshortened to 12mm by original 27mm, contraction in length 15mm, the bending radius of optical fiber 8 is reduced greatly, thereby convenient dish is fine, in addition, the total length of the LC joints of optical fibre has also shortened 15mm, shorten to 35mm by original 50mm, further dwindle the volume of the LC joints of optical fibre, save installing space, assemble convenient.
In the present embodiment, the contraction in length of pvc pipe 3, to 10mm, is worn to fibre convenient, can improve the assembling speed of the LC joints of optical fibre, for the fibre core that prevents optical fiber 8 dirt, the LC joints of optical fibre generally also are provided with dust cap 9.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
