In the fiber alignment process,, must guarantee the precision of fiber alignment position, and in the contraposition process, will guarantee the junction difficult drop-off for guaranteeing good transmission performance.And the joints of optical fibre optical fiber occurs through regular meeting and connect the situation that disengaging appears in contraposition place when construction at present.
The utility model content:
For this reason, the purpose of the utility model is to provide a kind of joints of optical fibre fixed sturcture, occurs the problem that breaks away from easily with solution existing fiber connector optical fiber connection contraposition place.
For realizing above-mentioned purpose, the utility model mainly adopts following technical scheme:
A kind of joints of optical fibre fixed sturcture; Comprise ceramic insertion core (1), caudal peduncle (2) and V-arrangement cover (11), said caudal peduncle (2) one ends are installed with ceramic insertion core (1), and the other end is connected with V-arrangement cover (11); Be provided with pre-buried bare fibre (8) in the said ceramic insertion core (1); This pre-buried bare fibre (8) front end is arranged in the V-shaped groove of V-arrangement cover (11), also is provided with a movable pressing board (3) in the V-shaped groove of said V-arrangement cover (11), and the top of this movable pressing board (3) front end is provided with a raised structures (14).
The outside of wherein said V-arrangement cover (11) also is provided with a fixing tapered sleeve (6), and above-mentioned raised structures (14) combines with the fixing inwall extruding of tapered sleeve (6).
The V-shaped groove rear end of wherein said V-arrangement cover (11) is provided with bearing pin (12), and movable pressing board (3) rear end is provided with through hole (13), and said bearing pin (12) correspondence is passed above-mentioned through hole (13).
The utility model is through being provided with a movable pressing board in V-shaped groove; And the front top at this movable pressing board is provided with a raised structures; When the fixed cone cover is nested with on this movable pressing board; Raised structures on the movable pressing board can produce extruding with the inwall of fixing tapered sleeve and combine, thereby whole V-arrangement is overlapped and movable pressing board is fixed and clamped.

Fig. 2 is an A-A cut-open view among Fig. 1.
Fig. 3 is the syndeton synoptic diagram of the utility model V-arrangement cover with movable pressing board.
Identifier declaration among the figure: ceramic insertion core 1, caudal peduncle 2, movable pressing board 3, elastic sponge body 4, optical fiber tightly overlaps 5, fixedly tapered sleeve 6, flexible bare fibre 7, pre-buried bare fibre 8, rotating shaft 9, butt joint optical fiber 10, V-arrangement cover 11, bearing pin 12, through hole 13, raised structures 14.
Embodiment:
For setting forth the thought and the purpose of the utility model, will combine accompanying drawing and specific embodiment that the utility model is done further description below.
See also Fig. 1, Fig. 2, shown in Figure 3, Fig. 1 is the structural representation of the utility model joints of optical fibre; Fig. 2 is an A-A cut-open view among Fig. 1; Fig. 3 is the syndeton synoptic diagram of the utility model V-arrangement cover with movable pressing board.The described joints of optical fibre fixed sturcture of the utility model is mainly used in after the optical fiber contraposition fixes contraposition place.
Wherein this joints of optical fibre fixed sturcture includes ceramic insertion core 1, caudal peduncle 2 and V-arrangement cover 11; Said caudal peduncle 2 one ends are installed with ceramic insertion core 1, and the other end is connected with V-arrangement cover 11 through rotating shaft 9, is provided with pre-buried bare fibre 8 in the said ceramic insertion core 1; And the front end of said pre-buried bare fibre 8 is arranged in the V-shaped groove of V-arrangement cover 11; Be provided with a movable pressing board 3 in the V-shaped groove of V-arrangement cover 11, said movable pressing board 3 rear ends are provided with through hole 13, and the V-shaped groove rear end correspondence position of V-arrangement cover 11 is provided with bearing pin 12; These bearing pin 12 correspondences are passed above-mentioned through hole 13; Movable pressing board 3 rear end with V-arrangement cover 11 is linked together, and movable pressing board 3 can be that rotating shaft is rotated with bearing pin 12, realize the folding that movable pressing board 3 and V-arrangement overlap 11 front ends.
The upper front end of movable pressing board 3 is provided with raised structures 14; And the arranged outside of V-arrangement cover 11 has fixedly tapered sleeve 6, when fixedly tapered sleeve 6 is pushed ahead, can produce the acting force that presses down to raised structures 14; Make movable pressing board 3 and V-arrangement cover fixing more firm between 11, be unlikely to produce and come off.
Also be provided with an elastic sponge body 4 between movable pressing board 3 and the pre-buried bare fibre 8, be adsorbed with optical fiber matching fluid in the said elastic sponge body 4.
The outside of flexible bare fibre 7 is the tight cover 5 of optical fiber; Inner core is butt joint optical fiber 10; When carrying out fiber alignment, at first fixedly tapered sleeve 6 is enclosed within on the flexible bare fibre 7, and makes movable pressing board 3 around bearing pin 12 opening of rotating opening V-shaped groove upwards; So that the butt joint optical fiber 10 of flexible bare fibre 7 can enter into the V-shaped groove of V-arrangement cover 11 smoothly, and with pre-buried bare fibre 8 contrapositions.
After butt joint optical fiber 10 and pre-buried bare fibre 8 contrapositions; Movable pressing board 3 is rotated around bearing pin 12; So that movable pressing board 3 is closed with V-shaped groove; Be arranged in the optical fiber matching fluid of V-shaped groove elastic sponge body 4 absorption this moment, then can under the extruding of movable pressing board 3, flow to the docking point place of butt joint optical fiber 10 and pre-buried bare fibre 8, to reduce the junction loss of bare fibre.
The fixedly tapered sleeve 6 that will be enclosed within then on the flexible bare fibre 7 is pushed ahead; It is entangled the V-arrangement cover 11 of fiber alignment position fully; Because the top of movable pressing board 3 front ends is provided with a raised structures 14; Inwall can form with this raised structures 14 and contact when fixedly tapered sleeve 6 advanced, thereby can guarantee that fixedly tapered sleeve 6, movable pressing board 3 and V-arrangement overlap closely fixing between 11 threes, prevented the disengaging of docking location.
More than be that a kind of joints of optical fibre fixed sturcture that the utility model is provided has carried out detailed introduction; Used concrete example among this paper the structural principle and the embodiment of the utility model are set forth, above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
