Abstract
The utility model provides a highly-stable optical fiber coupler. The highly-stable optical fiber coupler comprises a metal tube and a quartz groove arranged in the metal tube; substrate glue for a coupled optical fiber is fixed in the quartz groove; a heat shrink tube is sleeved on the quartz groove in a heat shrink packaging way; two ends of both the quartz groove and the heat shrink tube are sealed by sealant; external ends of the sealant is sealed by protection glue; the coupled optical fiber extends out of the metal tube from two ends of the quartz groove; a moisture absorbing rubber tape is wrapped around the heat shrink tube; and there is a gap between the moisture absorbing rubber tape and the inner wall of the metal tube, and the gap is filled with cotton. According to the utility model, the moisture absorbing rubber tape is wrapped around the heat shrink tube and the gap between the moisture absorbing rubber tape and the inner wall of the metal tube is filled with the cotton, so mechanic shock and vibration resisting and anti-moisture effects are achieved, stability of the optical fiber coupler is greatly improved, and easy operation and environment protection are achieved.
Description
Technical field
The utility model relates to a kind of optical communication class components and parts, particularly a kind of fiber coupler.
Background technology
The ordinary optic fibre coupling mechanism comprises (see figure 1): metal tube 1 ', and be positioned at the quartz cell 3 ' of metal tube 1 ', and coupled fiber 4 ' is fixed in quartz cell 3 ' with substrate glue 5 ', and the reusable heat draw 2 ' entangles quartz cell 3 ' pyrocondensation encapsulation.Coupled fiber 4 ' extends from quartz cell 3 ' to two ends, passes the two ends protective rubber 6 ' in metal tube 1 ', to metal tube 1 '.
This fiber coupler uses protection silica gel, plays anti-physical shock, mechanical vibration and moistureproof effect.But because of the protective rubber limited length of quartz cell two ends filling, moistureproof ability is very limited.And fill with protection silica gel in the gap between quartz cell and metal tube, when filling because of protection silica gel, bubble is arranged easily, in uneven thickness, can bring larger thermal stress when device is operated in high temperature or low temperature.The two deficiency makes ordinary optic fibre coupling mechanism high stability bad.
Qualitative in order to improve stabilized fiber, 2004-06-30 is disclosed, publication number is that the Chinese utility model patent of CN2622719Y has proposed a kind of packer for fiber coupler, in metal tube, add the scolding tin shutoff at coupled fiber two ends with the metal tail cap, and fill out again moistureproof glue in the outside, metal tail cap two ends, fill out again silica gel in the outside, moistureproof glue two ends.Although the method improves humidity resistance effectively, add the scolding tin shutoff because using the metal tail cap, operation inconvenience, cost Gao Mao.And in this structure, the gap between quartz cell and metal tube is without any filling material, and therefore anti-physical shock and vibration ability are not strong.
2010-06-09 is disclosed, publication number is that the Chinese utility model patent of CN201503507U has proposed a kind of high-stability optical fiber coupler, in metal tube, stifled with metal envelope disk seal at coupled fiber two ends, and fill out again the first fluid sealant, the second fluid sealant and protective rubber in the outside, metal envelope dish two ends.Fill with the dry thing of powdery in gap between quartz cell and metal tube, plays the effect of protection against the tide, anti-physical shock and vibrationproof.Although this patent is protection against the tide, antivibration and impact effectively, will effectively fill xeraphium and be not easy very much in very little gap, and in operating process, xeraphium can float in air, also not environmental protection.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of fiber coupler structure, can effectively improve the performance of protection against the tide, anti-physical shock and anti-mechanical vibration, easy operating and environmental protection again simultaneously.
The utility model is achieved in that a kind of high stability fiber coupler, comprise metal tube and the quartz cell that is positioned at metal tube, coupled fiber is fixed in quartz cell with substrate glue, the reusable heat draw entangles quartz cell pyrocondensation encapsulation, and at the two ends of quartz cell and heat-shrink tube sealant sealing, the outer end of fluid sealant seals with protective rubber again, described coupled fiber extends to outside metal tube from the two ends of quartz cell, wherein: be tied with moisture absorption adhesive tape on described heat-shrink tube, and have the gap between described moisture absorption adhesive tape and inner wall of metal tube, be filled with cotton in the gap.
In described metal tube and the two ends that are positioned at quartz cell also are respectively equipped with a metal plug; Described fluid sealant comprises the first fluid sealant, the second fluid sealant and the 3rd fluid sealant of arranging from inside to outside, and described metal plug is between the first fluid sealant and the second fluid sealant.
Described moisture absorption adhesive tape is banded moisture absorption adhesive tape.
The utility model has the advantage of: fiber coupler of the present utility model is tied with moisture absorption adhesive tape on heat-shrink tube, and leave the gap between moisture absorption adhesive tape and inner wall of metal tube, recharge cotton in the gap, play anti-physical shock and vibration, simultaneously also play moisture-proof role, greatly improved the stability of fiber coupler.And because using rubber bandage and cotton, easily operation and environmental protection.
Description of drawings
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of axially analysing and observe of ordinary optic fibre coupling mechanism.
Fig. 2 is the structural representation of axially analysing and observe of the utility model fiber coupler preferred embodiment.
Embodiment
See also shown in Figure 2, high stability fiber coupler of the present utility model, comprise metal tube 1 and the quartz cell 2 that is positioned at metal tube 1, coupled fiber 3 use substrate glue 4 are fixed in quartz cell 2, the reusable heat draw 5 entangles quartz cell 2 pyrocondensation encapsulation, and seal with fluid sealant 6 at the two ends of quartz cell 2 and heat-shrink tube 5, the outer end of fluid sealant 6 is again with protective rubber 7 sealings, described coupled fiber 3 extends to outside metal tube 1 from the two ends of quartz cell 2, wherein: be tied with moisture absorption adhesive tape 8 on described heat-shrink tube 5, for ease of operation, described moisture absorption adhesive tape 8 can adopt banded moisture absorption adhesive tape.And have the gap between described moisture absorption adhesive tape 8 and metal tube 1 inwall, be filled with cotton 9 in the gap.
In described the metal tube 1 and two ends that are positioned at quartz cell 2 also are respectively equipped with a metal plug 10; Described fluid sealant 6 comprises the first fluid sealant 61, the second fluid sealant 62 and the 3rd fluid sealant 63 of arranging from inside to outside, and described metal plug 10 is between the first fluid sealant 61 and the second fluid sealant 62.Make moisture effect better.
Fiber coupler of the present utility model is tied with moisture absorption adhesive tape on heat-shrink tube, and leave the gap between moisture absorption adhesive tape and inner wall of metal tube, recharge cotton in the gap, play anti-physical shock and vibration, simultaneously also play moisture-proof role, greatly improved the stability of fiber coupler.And because using rubber bandage and cotton, easily operation and environmental protection.
Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
