Abstract
The utility model relates to a union joint of an optical fiber movable connector, comprising a frame sleeve, a ceramic lock pin and a closing ring. The tailstock of the ceramic lock pin is provided with a positioning slot; a positioning key integrated with the inner wall of the frame sleeve is provided with the inner diameter of the frame sleeve. The tailstock is fixed on the frame sleeve by the tailstock positioning slot combined with the positioning key. The positioning key is integrated with the frame sleeve wall, which has high strength, uneasy damage when assembling and simple installing, improves production efficiency, and the closing ring is used for fixing optical fiber cables, which increases the stability.
Description
Technical field
The utility model relates to communication field, more particularly, relates to a kind of connector of fiber active linker.
Background technology
What fiber active linker solved is the problem that continues of two optical cables, promptly by the mechanical centralising device that is arranged in the connector laser beam of source optical fiber is incided in the receiving end optical fiber as much as possible, this mechanical centralising device is the physical arrangement basis of realizing optically-coupled.Fiber active linker comprises a pair of connector that is used for fixing optical cable and is used to be connected two connectors, accurately guarantees the concentricity of the ceramic insertion core in two connectors, the adapter of two sections optical cables connection centerings will dock.Connector is used for fixing optical cable, generally the naked fibre behind the optical cable baring is penetrated ceramic insertion core, and the some adhesive curing, reaches the order ground of fixed fiber; Ceramic insertion core is then fixed by tailstock, and then cooperates with the locating slot of tailstock by the location jaw of stop collar, reaches the final fixing and protection of optical cable and optical fibres.Connector is the necessary concentricity that accurately guarantees the ceramic insertion core in naked fibre and the connector of optical cable fixedly; The structure of connector will fully guarantee the installation accuracy of form and position and the stress intensity of ceramic insertion core.
Be illustrated in figure 1 as the synoptic diagram that the locating ring of former connector cooperates with the tailstock of ceramic insertion core, the location jaw 7 by stop collar 3 cooperates with the locating slot of tailstock 2 and reaches the fixedly purpose of tailstock.Stop collar 3 and frame cover 6 is for being threaded, because the physical dimension of stop collar is subjected to the integrally-built restriction of connector, size, the thickness low LCL of locating jaw 7 cause insufficient strength, makes that the quality of fit of location jaw of tailstock locating slot and stop collar is relatively poor.And in assembling, usually need to change a little, rotate when promptly installing and regulate ceramic insertion core to reach the purpose of two optical cable centerings, if the insufficient strength of stop collar just causes breakage especially easily like this, influence the production efficiency waste material.
The problem that prior art exists be the location jaw of stop collar when cooperating with the locating slot of tailstock precision relatively poor, main cause is that the dimensional thickness of the location jaw of stop collar causes insufficient strength inadequately, and the dimensional thickness of stop collar is subjected to the integrally-built restriction of connector, can not rely on the increase dimensional thickness to gain in strength.When connector assembled on the other hand, the assembling of stop collar and tailstock was also difficult, and the location jaw insufficient strength because of stop collar causes breakage easily, and stop collar is reinstalled in case damage must be changed stop collar again, influences production efficiency, waste material.
The utility model content
The technical problems to be solved in the utility model is, in assembling process, cause the defective of stop collar breakage easily at the connector of existing above-mentioned fiber active linker, a kind of intensity height is provided, when assembling, does not allow the connector of flimsy fiber active linker.
The technical scheme that its technical matters that solves the utility model adopts is: construct a kind of fiber active linker, comprise a pair of connector that is used for fixing optical cable; Connector comprises a stop collar, be inserted in ceramic insertion core in the stop collar, pass ceramic insertion core and with the frame cover of stop collar by being threaded, the tailstock of described ceramic insertion core has locating slot.On the internal diameter of frame cover the positioning key that is connected as a single entity with the frame jacket wall is arranged, positioning key can cooperate with the locating slot of tailstock and tailstock is fixed in the frame cover.In the utility model, change stop collar and cooperating of tailstock and be cooperating of frame cover and tailstock, reach the fixedly purpose of tailstock.
Fiber active linker described in the utility model, the internal diameter of frame cover has the positioning key that is connected as a single entity with the frame jacket wall, and positioning key cooperates with the locating slot of tailstock and tailstock is fixed in the frame cover.The frame cover pass ceramic insertion core again with stop collar by being threaded togather, finally realize optical cable fixing in lock pin and connector.At fiber active linker described in the utility model, stop collar still keeps the fixedly effect of optical cable and fixed frame cover.
The beneficial effects of the utility model are that because positioning key and frame sleeve wall thickness are connected as a single entity, the intensity height is not easy to cause damage during assembling, and assembling is simple, has improved production efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the cut-away view of prior art fiber active linker connector;
Fig. 2 is the cut-away view of fiber active linker connector of the present utility model;
Fig. 3 is the partial enlarged drawing cut-away view of Fig. 2.
Embodiment
As shown in Figure 1 and Figure 2, one of effect of fiber active linker connector is fixing optical cable.Its assembling process is: earlier optical cable 4 is penetrated stop collar 3, the trivial part such as cover that fastens, then optical cable one end strip off is penetrated ceramic insertion core 1 with naked fibre after a bit of, be fixed on naked fibre in the ceramic insertion core and put adhesive curing; Behind the ground fiber end face, frame cover 6 is passed ceramic insertion core, the positioning key 5 of frame cover is matched with the pickup groove of ceramic insertion core tailstock, reach the fixedly purpose of ceramic insertion core tailstock, frame is overlapped 6 be connected by rib-loop with stop collar 3; Fix overall optical cable end and frame and overlap 6 cooperate by the trivial cover that fastens at last.
As Fig. 2, shown in Figure 3 be that positioning key 5 in the connector frame of the present utility model cover overlaps synoptic diagram with frame after the tailstock 2 of ceramic insertion core 1 cooperates; Change stop collar 3 and cooperating of tailstock 2 and be cooperating of frame cover 6 and tailstock 2, reach the fixedly purpose of tailstock, overlap internal diameter because the positioning key 5 that frame overlaps is arranged on frame, be connected as a single entity with the frame sleeve wall thickness, make its intensity height, assembling is changed and a little also is not easy to cause damage, makes assembling process simpler.Stop collar 3 is still with frame cover 6 and is threaded, and the effect of the stop collar in the utility model is still fixedly optical cable and frame cover.
