Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Fiber adapter as shown in Figures 1 to 4, comprise shell body 1 and be sheathed on the sleeve 2 in shell body 1, on described sleeve 2 middle part outer walls, edge is circumferentially with annular projection 21, the inwall of described shell body 1 is provided with and annular projection 21 stage portion 11 coordinating that offsets, between one end of described shell body 1 and stage portion 11, be provided with internal thread 12, described shell body 1 is spirally connected and is provided with and annular projection 21 baffle ring 3 coordinating that offsets by internal thread 12, and described annular projection 21 is fixed between baffle ring 3 and stage portion 11.
When the utility model is installed, first sleeve 2 is sheathed in shell body 1, then coordinates with stage portion 11 by baffle ring 3 and make annular projection 21 fixing, and then played the effect of fixed muffle 2, install more for convenience, and processing is comparatively simple, accuracy requirement is lower, effectively reduces processing cost.
In described sleeve 2, be provided with thin plate 4, described thin plate 4 is concentric co-axial setting with sleeve 2, the center of described thin plate 4 is provided with through hole 41, as shown in Figure 2, when input optical fibre contact pin 100 is with output optical fibre contact pin 200 during respectively from relative insertion the in sleeve 2 two ends, under the effect of thin plate 4, two contact pins are separated, thereby avoided the end face of input optical fibre 101 and the direct close contact of end face of output optical fibre 201, input optical fibre 101 is coupled with output optical fibre 201 by described through hole 41.
Main attention be, in the specific implementation, the diameter of through hole 41 need be greater than the diameter of optical fiber, does not contact with thin plate 4 with the end face that ensures input optical fibre 101 (or output optical fibre 201), thereby effectively avoid fiber end face to occur wear phenomenon, ensured the smooth finish of fiber end face.Due to being set, thin plate 4 reduces the coupling efficiency of losing between optical fiber 101 and output optical fibre 201, therefore need to the thickness of thin plate 4 be accomplished less when design as far as possible, particularly, the thickness of thin plate 4 described in the utility model is 0.05～0.10 millimeter, thus, effectively ensure the coupling efficiency of optical fiber, light signal can be transmitted more accurately.
Described thin plate 4 both sides are respectively equipped with the lining 5 with sleeve 2 inwall interference fit, described thin plate 4 is fixed and is located in sleeve 2 by two linings 5, under the engagement limits effect of two linings 5, ensure that thin plate 4 can remain plumbness with the axis of sleeve 2, avoided thin plate 4 to occur sliding or obscission, stability is better.
The end of described two linings 5 is respectively equipped with the cylinder 6 with sleeve 2 inwall interference fit, the barrel of the described cylinder 6 wherein heart is recessed to form elastic 61, by elastic 61 is set, in the time that contact pin inserts sleeve 2, cylinder 6 can play fastening effect to contact pin under the effect of elastic 61, meanwhile, and because elastic 61 has elasticity, the utility model can be cooperatively interacted with the contact pin of different model, expanded the scope of application of the present utility model.
Described shell body 1 one end is spirally connected and is provided with the first dust cap 7 by described internal thread 12, the other end outer wall of described shell body 1 is provided with external thread 13, described shell body 1 is spirally connected and is provided with the second dust cap 8 by external thread 13, between described the second dust cap 8 and shell body 1, is connected with chain 9.When use, because input optical fibre 101 is normally drawn and is fixed on the utility model from device interior, general input optical fibre contact pin 100 inserts rear less the extracting of sleeve 2, therefore without between the first dust cap 7 of the present utility model and shell body 1, web member being set, on the contrary, because output optical fibre 201 need to frequently insert or extract, the number of times that the second dust cap 8 mounts and dismounts is thereupon more, therefore for preventing that Loss from appearring in the second dust cap 8, be connected with chain 9 between the second dust cap 8 of the present utility model and shell body 1.
Between described cylinder 6 and lining 5, be all embedded with pad 22 between lining 5 and thin plate 4, pad 22 is set, effectively prevents from occurring wear phenomenon between cylinder 6 and lining 5, lining 5 and thin plate 4.Between the periphery of described thin plate 4 and its through hole 41, be netted setting, increase the penetrating area of thin plate 4, further improve the coupling efficiency between input optical fibre 101 and output optical fibre 201, reduced the impact because the optical signal transmission decrease in efficiency that thin plate 4 causes is set.Between described the first dust cap 7 and shell body 1, be equipped with sealing gasket 14 between the second dust cap 8 and shell body 1, by sealing gasket 14 is set, in the time that the first dust cap 7, the second dust cap 8 are connected with shell body 1 respectively, effectively strengthen sealing effectiveness, avoided the impurity such as dust to penetrate in sleeve 2.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
