Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fiber adapter as shown in Figures 1 to 4, the sleeve 2 comprising shell body 1 and be sheathed in shell body 1, in the middle part of described sleeve 2, outer wall is circumferentially provided with annular projection 21, the inwall of described shell body 1 is provided with the stage portion 11 coordinated that to offset with annular projection 21, internal thread 12 is provided with between one end of described shell body 1 and stage portion 11, described shell body 1 is spirally connected by internal thread 12 and is provided with the baffle ring 3 coordinated that to offset with annular projection 21, and described annular projection 21 is fixed between baffle ring 3 and stage portion 11.
When the present invention installs, first sleeve 2 is sheathed in shell body 1, is then coordinated with stage portion 11 by baffle ring 3 and annular projection 21 is fixed, and then serve the effect of fixed muffle 2, install more for convenience, and processing is comparatively simple, accuracy requirement is lower, effectively reduces processing cost.
Thin plate 4 is provided with in described sleeve 2, described thin plate 4 is arranged in concentric co-axial 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 and output optical fibre contact pin 200 insert from sleeve 2 two ends are relative respectively, separated by two contact pins under the effect of thin plate 4, thus avoid 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, to ensure that the end face of input optical fibre 101 (or output optical fibre 201) does not contact with thin plate 4, thus effectively prevent fiber end face and occur wear phenomenon, ensure that the smooth finish of fiber end face.The coupling efficiency lost between optical fiber 101 and output optical fibre 201 is reduced owing to arranging thin plate 4, therefore during design need the thickness of thin plate 4 to accomplish less as far as possible, specifically, the thickness of thin plate 4 of the present invention is 0.05 ~ 0.10 millimeter, thus, effectively ensure that the coupling efficiency of optical fiber, light signal is 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 in sleeve 2 by two linings 5 cooperations, under the cooperation restriction of two linings 5, ensure that thin plate 4 can remain plumbness with the axis of sleeve 2, avoid 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 arranging elastic 61, when contact pin inserts sleeve 2, cylinder 6 can play fastening effect to contact pin under the effect of elastic 61, meanwhile, because elastic 61 has elasticity, the present invention can be cooperatively interacted with the contact pin of different model, expand the scope of application of the present invention.
Described shell body 1 one end is spirally connected by described internal thread 12 and is provided with the first dust cap 7, the other end outer wall of described shell body 1 is provided with external thread 13, described shell body 1 is spirally connected by external thread 13 and is provided with the second dust cap 8, is connected with chain 9 between described second dust cap 8 and shell body 1.During use, normally draw from device interior due to input optical fibre 101 and fix on the invention, general input optical fibre contact pin 100 is less after inserting sleeve 2 to be extracted, therefore without the need to arranging web member between the first dust cap 7 of the present invention and shell body 1, on the contrary, because output optical fibre 201 needs frequently to insert or extract, the number of times that second dust cap 8 mounts and dismounts is thereupon more, therefore for preventing the second dust cap 8 from occurring Loss, between the second dust cap 8 of the present invention and shell body 1, be connected with chain 9.
Between described cylinder 6 and lining 5, between lining 5 and thin plate 4, be all embedded with pad 22, pad 22 is set, effectively prevent cylinder 6 and lining 5, between lining 5 and thin plate 4, occur wear phenomenon.In netted setting between the periphery of described thin plate 4 and its through hole 41, increase the penetrating area of thin plate 4, further increasing the coupling efficiency between input optical fibre 101 and output optical fibre 201, reducing the impact because arranging the optical signal transmission efficiency decline that thin plate 4 causes.Between described first dust cap 7 and shell body 1, between the second dust cap 8 and shell body 1, be equipped with sealing gasket 14, by arranging sealing gasket 14, when the first dust cap 7, second dust cap 8 is connected with shell body 1 respectively, effectively enhance sealing effectiveness, avoid the impurity such as dust and penetrate in sleeve 2.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
