Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, need to prove: the direction with ceramic insertion core in following examples is the place ahead, is the rear with tail cover direction.
Embodiment, see shown in Figure 1: ceramic insertion core 10 axis place hollows, its hollow diameters penetrates for just in time making the naked fibre of optical fiber.Its rear end has a big mouth of osculum trumpet-shaped targeting port backwards forward.Its rear portion peg graft into and be fixed in the front portion of caudal peduncle 20, as Fig. 2, Fig. 3, shown in Figure 4, caudal peduncle 20 usefulness copper materials are manufactured, caudal peduncle 20 front end outside surfaces are provided with step 21, and are corresponding, as shown in Figure 1, inside casing overlaps 100 inside and is provided with greater than the diameter of ceramic insertion core 10 less than the baffle ring of step 21 external diameters, when the caudal peduncle 20 that is plugged with ceramic insertion core 10 pierced into inside casing and overlaps 100, ceramic insertion core 10 can protrude out, and caudal peduncle 20 is then stopped by baffle ring.Baffle ring is provided with and only revolves the projection (not shown), and is corresponding, as Fig. 2, Fig. 3, shown in Figure 4, step 21 be provided with match only revolve groove 22.Only revolve projection for along two of axis symmetry, only revolve groove 22 for along four of axis symmetry, the cyclone of ending that forms like this makes caudal peduncle 20 overlap in 100 at inside casing can not to rotate, and order ground is to be convenient to clamping screw 60 be screwed onto on the caudal peduncle 20.Certainly, this ends cyclone also can be other common modes, cooperates etc. with polygonal such as polygon.What be spirally connected with caudal peduncle 20 is an optical fiber intermediate protective layer; the clamp device that the promptly normal optical fiber of saying is 0.25 layer; this clamp device can be a lot of common modes, such as being an energy and the clip 91 that inside casing cover 100 directly or indirectly is connected, by external pressure the optical fiber intermediate protective layer is clamped.Like this, when external force acted on optical cable, because the existence of clamp device, the inside casing that acts on that external force is indirect overlapped 100, has increased tensile strength.
To shown in Figure 10, preferred clamp device is: the cooperation of Fastener 50, Microspring 80 and clamping screw 60 as Fig. 5.As Fig. 5, Fig. 6, shown in Figure 7, Fastener 50 is anterior big, and the rear portion is little, is vertebra shape, and metal is made, and head has shrinkage joint 51, preferably four.Certainly, the rear end also has the trumpet-shaped targeting port that can make things convenient for optical fiber to pass.Before the clamping screw that is mated 60, inside has the mouth that can slide for Fastener 50.Obviously, Kou diameter greater than the top diameter of Fastener 50 less than its diameter at butt end.Clamping screw 60 inside are provided with Microspring 80 and have bell-mouthed guiding microtubule 70 in the optical fiber insertion end equally.When external force during less than the expansion force of Microspring 80, Fastener 50 stretches out outward like this, and it is big that its inner aperture becomes, and help the naked fibre of optical fiber and pass through this moment; Otherwise when external force during greater than the expansion force of Microspring 80, Fastener 50 enters toward in, and its inner aperture diminishes, and helps the naked fibre of grip optical fibers this moment.And this external force comes from and acts on the turn that clamping screw 60 is connected with the spiral shell of caudal peduncle 20, because the aforementioned existence that ends cyclone, when needs, clamping screw 60 can rotate easily, thereby turnover caudal peduncle 20 rear portions obtain suitable external force with this.Certainly, in order to stop because of pressure is excessive light to be pressed down, as Fig. 8, Fig. 9 and shown in Figure 10, clamping screw 60 front portions also are provided with the decompression seam 61 of some, and it can be two.More than the coaxial hollow integral body of Xing Chenging need be encapsulated in the inside casing cover 100, and the mode of employing is that the rear portion encapsulates with retainer 40.
As Figure 11, Figure 12, shown in Figure 13, retainer 40 outer front end are provided with location convex clip 41, as shown in Figure 1, be provided with positioning port in inside casing cover back, inside accordingly, when pressure act on retainer 40 make location convex clip 41 enter positioning port the latter two achieve a fixed connection.The front of retainer 40 is placed with spring 30, and the two ends of spring 30 act on the front end of retainer 40 and step 21 trailing flanks of caudal peduncle 20 respectively, thereby aforementioned coaxial hollow integral body is pressed in the inside casing cover 100 fully.Retainer 40 rear portions are provided with external thread, and optical cable fixed cover 90 is screwed onto on the retainer 40.Like this, the skin of optical fiber is also clamped, and indirect being fixed on the inside casing cover 100, has increased the tensile strength of the optical fiber that connects once more.After 90s of this optical cable fixed cover can be with tail cover 300, and it can be plastic production.
Optical cable fixed cover 90 is a metal adapter sleeve that can be screwed onto retainer 40 rear portions, and its inside is packaged with clip 91 as shown in figure 14.After optical fiber passes, with pliers optical cable fixed cover 90 inside collars 91 are compressed, can the grip optical fibers skin.
