Abstract

The utility model relates to an adapter for an optical fiber movable connector, and the optical fiber movable connector comprises two fixing optical fiber cable connectors and an adapter for accurately guarantee the concentricity of the ceramic lock pins in the two connectors. The adapter comprises one ceramic open tube and two liner tubes; one of the liner tubes has a long tube which is integrated with the liner tube and matches with the ceramic open tube in length, and which sleeves completely the ceramic open tube to protect efficiently the ceramic open tube. The acting force at two liner tube joint does not directly act on the ceramic open tube, and thus the ceramic open tube is not easy to damage during assembling process. The utility model reduces the disability rate of the adapter during assembling process.

Description

The adapter of fiber active linker

Technical field

The utility model relates to technical field of optical fiber communication, more particularly, relates to a kind of adapter of fiber active linker.

Background technology

What fiber active linker solved is the problem that continues of two optical fiber, 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.Adapter comprises a sleeve, two bushing pipes that the phase interworking is suitable, and two liner sleeves are on sleeve.As shown in Figure 1, be the synoptic diagram that connector 1 combines with adapter 2, the ceramic insertion core in the connector 1 of fiber active linker need connect with adapter 2, reaches the purpose of the centering of optical cable.

Two bushing pipe profiles of traditional adapter are identical, and each protects the half sleeve.Because adapter is in assembling process, can make sleeve be subjected to shear stress bigger, be easy to generate breakage, particularly at the interface of two bushing pipes, the stress of the vertical axial that can bring.Be illustrated in figure 3 as the synoptic diagram of three steps of the bushing pipe assembling of original technology, the first step will one section bushing pipe 5 wherein be enclosed within an end of sleeve; Second the step with the other end of another liner sleeve at sleeve, at last by ring flange 4 fixedly bushing pipe make it to become state shown in Figure 2.Ring flange 4 can make sleeve 3 be subjected to the acting force of vertical axial fixedly the time, sleeve 3 is very big in the power that the interface of bushing pipe is subjected to, in assembling process, be easy to make sleeve to damage, the core devices of adapter is a sleeve, if sleeve damages, whole adapter has also just been scrapped, and causes the very big production efficiency of the proportion of goods damageds of sleeve to reduce, and causes the waste on time, the human and material resources.

The utility model content

The technical problems to be solved in the utility model is, at the defective that the adapter of the fiber active linker of prior art damages when the assembling easily, provides a kind of adapter of the fiber active linker that the proportion of goods damageds are low in assembling process.

The technical scheme that its technical matters that solves the utility model adopts is: the adapter of constructing a kind of light flexible jumper, comprise a sleeve, a pair of be inserted in from the two ends of sleeve respectively and matching of linking together by coupling arrangement with sleeve and two bushing pipes.One of them bushing pipe has one section long tube that possesses defencive function with its one; this bushing pipe and sleeve match and the time; can be wherein with sleeve cover, the another lining pipe inserts and is connected with aforementioned bushing pipe by coupling arrangement from the port of long tube and touches together.

At fiber active linker described in the utility model, the length of the bushing pipe endoporus of belt length pipe just can be overlapped sleeve therein fully.

Because the beneficial effect of the adapter of fiber active linker of the present utility model is; owing to have a bushing pipe to have one section long tube that possesses defencive function in two bushing pipes; sleeve can be overlapped therein fully; it is protected; the acting force of the interface of two bushing pipes just can not act directly on the sleeve; sleeve just is not easy to damage in assembling process like this, has reduced the scrappage in assembling process of matching device.

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 synoptic diagram of connector and adapter combination;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is the synoptic diagram of the bushing pipe assembling of prior art;

Fig. 4 is the synoptic diagram of the utility model bushing pipe assembling.

Embodiment

Be illustrated in figure 4 as the synoptic diagram of three steps of bushing pipe assembling of the present utility model; the step of bushing pipe assembling of the present utility model and the bushing pipe installation step of prior art are basic identical; difference be in; there is a bushing pipe 7 to have a long tube that possesses defencive function 6 with its one in two bushing pipes; earlier sleeve 3 is inserted and have in the bushing pipe 7 of long tube 6; sleeve 3 is protected fully; and then another bushing pipe 5 is enclosed within on the long tube 6; the acting force of the interface of two sections bushing pipes just can not act directly on the sleeve 3; sleeve just is not easy to damage in assembling process like this; and possesses identical contour structure size after two bushing pipes cooperations; can be compatible fully with original adapter ring flange 4 and sleeve 3, reduced the proportion of goods damageds of material; improved production efficiency.

Claims

1, a kind of adapter of fiber active linker; comprise a sleeve (3); two bushing pipe (5) and bushing pipes (7) that are inserted in from the two ends of sleeve (3) and link together respectively; it is characterized in that, described bushing pipe (7) have one with its one, be complementary on length with sleeve (3), sleeve (3) can overlap fully the long tube (6) of realizing that therein overall length is protected.

2, fiber active linker according to claim 1 is characterized in that, the length of the endoporus of described bushing pipe (7) and sleeve (3) cover equal in length therein.
