Lid 2 is block, both sides are extended with pawl 22 downwards, be positioned at the both sides of the long and narrow groove 13 of fibre junction supporting seat 1, when sliding members 3 pushes a high position to from the inclined-plane low level of the upper surface of lid 2 time, lid is compacted, two pawls all outwards open, thus keep a firm hand on the surface of long and narrow groove 13 both sides of fiber support seat 1.
The embodiment of the joints of optical fibre of the present invention also comprises optic fibre fixing device 7, for optical fiber 6 fixedly to be continued, optical fiber front portion to be continued naked fine 61 for realizing continuing with naked fine 51 of pre-buried optical fiber 5; The naked fine part of the end rear portion right and wrong that continue, namely has the part 62 of fiber optic protection layer.Front end and the housing 4 of optic fibre fixing device 7 are fixed.Particularly, as shown in the figure, respectively there is a projection (corresponding to claw above) 71 both sides, front end of optic fibre fixing device, and the corresponding site of housing has mating holes 43, can hold complementary protuberance 71, thus both is fixed together.An elastic body is also comprised, as spring 72 between fibre junction supporting seat and optic fibre fixing device.When by fiber stub Payload attach fitting (not shown) time, spring can apply a reacting force to fiber stub, thus ensures reliable connection.Concrete, spring is assemblied in the outside of the slender conduit of fibre junction bracing or strutting arrangement, stopped by the second end of fibre junction supporting seat, and opposite side is stopped by the front end of optic fibre fixing device.Compressive state is kept after spring assembling.
The other end of described optic fibre fixing device 7 is formed as the tubular body 74 of the fixed part of fiber optic protection layer 62; Pars intermedia between one end of described optic fibre fixing device 7 and the other end is formed with the longitudinal grooved 73 extended in described longitudinal direction, naked fine 61 of optical fiber 6 to be continued described in this longitudinal grooved 73 extends radially inwardly to expose, and described in treat that naked fine 61 of jointed fiber 6 are suitable for radially bending in described longitudinal grooved 73; Opening via described longitudinal grooved 73 is suitable for seeing the naked fibre of drawing from fiber optic protection layer 62.When naked fibre and pre-buried optical fiber contact time, naked fibre can produce slight bending, and ensures that contact is good.
The embodiment of the joints of optical fibre of the present invention also comprises a fixing tail cover 8, and leading inside has internal thread, matches with the external thread of groove body front portion.Rear portion is porose, and optical fiber can be passed.Fixing tail cover is made up of two parts, and the material that anterior quality is harder is made, and as rigid plastic etc., rear portion is made up of the material of softness, thus ensure optical fiber can not bending angle too large, thus ensure the transmission performance of optical fiber.
These joints of optical fibre also comprise a shell 9, are assemblied in the outside of housing, and when the joints of optical fibre are connected to adapter time, itself and adapter match, thus ensure the connection of itself and adapter.
The using method of the embodiment of the joints of optical fibre of the present invention is described below.First will have the optical fiber stripping one section of protective seam, and expose naked fibre, make naked fibre may be used for continuing.Optical fiber is inserted in fibre junction supporting seat 1 by optic fibre fixing device, achieves a butt joint with pre-buried optical fiber.When fibre junction, pushed forward optical fiber, make the part slight curvature of naked fibre in longitudinal grooved 73 (can see), thus ensure that fiber alignment is good, then with hand, optical fiber is temporarily fixed on optic fibre fixing device 7, another hand propelled sliding members 3 afterwards, the surface 32 of sliding members 3 overcomes the elasticity of elastic body 22 and promotes press section 2 towards optical fiber and move, until extruding optical fiber (as Fig. 6 to Fig. 7), until fibre junction and compacted after, loosen bending optical fiber, fixing tail cover 8 is fixed on optic fibre fixing device 7 by screw thread, thus final fixed fiber, put shell 9 and protective cover again, the connection of the joints of optical fibre just completes.When needs are changed or dismantle optical fiber, first fixing tail cover 8 is backed out, then promote sliding members 3 to move in the opposite direction, thus the surface 32 of sliding members 3 discharges the pressing to press section 2 gradually, simultaneously, press section is also pushed away pressing position until discharge (as Fig. 7 to Fig. 6) completely by elastic body 22 gradually, afterwards, can extract out naked fine 61 and be removed from optic fibre fixing device 7 by optical fiber 6.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can change these embodiments without departing from the principles and spirit of the present invention.The scope of application of the present invention is by claims and equivalents thereof.
