A kind of fiber active linker, include connector body, tail portion of connector and the optical fiber worn to connector body by tail portion of connector or single fiber cable, tail portion of connector comprises memory sleeve pipe and is coated at the tail cover of this memory sleeve pipe, memory sleeve pipe prolongs its length direction and comprises the first sleeve pipe and the second sleeve pipe, described first set pipe is for holding the tail end of connector body, optical fiber or single fiber cable are separated as fibre core and fibre core skin at the first sleeve pipe place, the tail end of fibre core external sheath connector body, fibre core is through connector body, the tail end of connector body and fibre core skin, first sleeve pipe riveting connects.

Further, described fiber active linker is LC type, SC type, FC type or ST type fiber active linker.

Further, be placed on the tail end of first set pipe in the front end of described second sleeve pipe, the diameter of described second sleeve pipe is corresponding with the diameter of optical fiber or single fiber cable.

Further, described memory sleeve pipe is that metal or plastics are made.

Further, described tail cover is made for rubber or plastics.

Further, tail is arranged with the fluting that multiple outside surface overlapped from described tail extends to memory sleeve pipe, and described multiple fluting is perpendicular to axial direction and parallel to each other.

Further, the coated fiber of described optical fiber to be diameter be 0.9mm or 0.25mm.

Further, the fibre core skin of described single fiber cable comprises oversheath and tension aramid fiber.

Further, single core inside cable of described single fiber cable to be diameter be 3.0mm or 2.0mm.

The beneficial effects of the utility model are: due to the tail end of fibre core external sheath connector body, fibre core is through connector body, the tail end of connector body is outer with fibre core, the first sleeve pipe riveting is connected, not only increase the length of memory sleeve pipe, significantly improve the flexible radius of tail portion of connector and radian, it also avoid parts in BENDING PROCESS simultaneously and, by the hidden danger pulled, improve the reliability that product uses.

Embodiment

In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model being described further and illustrating.

Fig. 1 ~ 4 show as a kind of fiber active linker, include connector body 10, tail portion of connector 20 and the optical fiber 30 worn to connector body by tail portion of connector or single fiber cable.The present embodiment is for coated fiber, this optical fiber 30 diameter is 0.9mm or 0.25mm, connector body 10 can be various existing structure, as shown in figs. 2 to 4, this connector body 10 comprises lock pin 11, fixing headgear 12, coupling cap 13, stop collar 14, the tail end of described lock pin 11 is also set with spring 15, the tail end of lock pin 11 is inserted in stop collar 14, lock pin 11 is connected by keyway arrangements with fixing headgear 12, fixing headgear 12 is connected together with the cap 13 that is coupled, stop collar 14 is for being connected with tail portion of connector 20, the front end of the coated tail portion of connector 20 of afterbody of coupling cap 13, and be connected together with tail portion of connector 20.Composition graphs 5, shown in Fig. 6, in certain embodiments, tail portion of connector 20 comprises memory sleeve pipe 21 (being made up of metal or plastic or other material) and is coated at tail cover 22 (being made up of rubber or plastic or other material) of this memory sleeve pipe 21, memory sleeve pipe 21 prolongs its length direction and comprises the first sleeve pipe 211 and the second sleeve pipe 212, described first sleeve pipe 211 is for holding the tail end 141 of the stop collar 14 shown in the tail end of connector body 10 and figure, optical fiber 30 is separated into fibre core 31 and fibre core skin 32 at the first sleeve pipe 211 place, the tail end 141 of the outer 32 coated stop collars 14 of fibre core, fibre core 31 is through connector body 10, tail end 141 and the fibre core skin 32 of stop collar 14, first sleeve pipe 211 riveting connects.Understandable, the structure of above-mentioned tail portion of connector 20 goes for the fiber active linker of various model, as LC type, SC type, FC type, ST type fiber active linker etc.

Due to the tail end of the outer 32 coated connector bodies 10 of fibre core, fibre core 31 is through connector body 10, the tail end of connector body 10 is connected with fibre core skin 32, first sleeve pipe 211 riveting, not only increase the length of memory sleeve pipe 21, significantly improve the flexible radius of tail portion of connector 20 and radian, it also avoid parts in BENDING PROCESS simultaneously and, by the hidden danger pulled, improve the reliability that product uses.
