The connector has simple structure and can be used and assembled conveniently.
Description
Technical field
The utility model relates to joints of optical fibre technical field, relates in particular to a kind of SMA type fiber active linker.
Background technology
The joints of optical fibre be optical fiber with optical fiber between carry out the device that detachable (activity) is connected, it is the accurate butt joint of two end faces of optical fiber, so that being coupled to receive in the optical fiber to greatest extent, the luminous energy of launching fiber output goes, and make because it is got involved optical link and the influence that system causes is reduced to minimum, this is the basic demand of the joints of optical fibre.To a certain extent, the joints of optical fibre have also influenced reliability and every performance of optical transmission system.
The joints of optical fibre can be divided into single mode, the multimode connector of common silica-based optical fibers by the difference of transmission medium, also have other as being the joints of optical fibre of transmission medium with plastic cement etc.; Can be divided into by connector version: FC, SC, ST, LC, D4, DIN, MU, MT or the like various forms.
Short-range communication (user and LAN (Local Area Network)) idling slow speed system generally can be considered the multimode optical fiber connector more, SMA type fiber active linker then is exclusively used in idling slow speed system, be used for CATV underground line, testing apparatus, active equipment terminal and related data network more, but existing this model connector, structure is compact inadequately, inserts the loss height.
The utility model content
Be to solve the deficiencies in the prior art, the utility model provides a kind of and can effectively prevent to come off, SMA type fiber active linker easy for installation, and it is simple in structure, and low cost of manufacture is easy to use.
For achieving the above object, SMA type fiber active linker of the present utility model, comprise hollow tailstock, have the contact pin of the optic fibre hole that passes through for optical fiber, the outer sleeve that has internal thread that links to each other with adapter, rearmounted sleeve, tail cover, the front end of described contact pin and tailstock is fixedly linked, and described tailstock rear end is set with rearmounted sleeve, is set with the tail cover on the rearmounted sleeve.
Further, front end is fixed with limited block on tailstock, and tail end is fixed with block, and described outer sleeve suit is positioned on the tailstock between limited block and the block.
In addition, the further improvement as aforesaid way is set with dust cap on the described contact pin.
Adopted technique scheme, in use, can make the lock pin plug-in mounting after, effectively avoid coming off, and make contact pin location accurately; Contact pin can adopt the metallic body, and corrosion resistivity is preferably arranged, and ceramic insertion core adopts the design that suspends, and has low insertion loss; Add dust cap, prevent that lock pin is infected with dust, it is simple in structure, compact, uses, easy for installation.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the present invention is done further to describe in detail:
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
By as can be known shown in Figure 1, SMA type fiber active linker of the present utility model, comprise hollow tailstock 1, have the contact pin 3 of the optic fibre hole 2 that passes through for optical fiber, the outer sleeve that has internal thread 4 that links to each other with adapter, rearmounted sleeve 5, tail cover 6, described contact pin 3 is fixedly linked with the front end of tailstock 1, and tailstock 1 rear end is set with rearmounted sleeve 5, is set with tail cover 6 on the rearmounted sleeve 5.Front end is fixed with limited block 7 on tailstock 1, and tail end is fixed with block 8, and outer sleeve 4 suits are positioned on the tailstock 1 between limited block 7 and the block 8.Be set with dust cap 9 on the contact pin 3.
The assembly method of SMA type fiber active linker of the present utility model is as follows: optical fiber cable is run through in the rearmounted sleeve, hair is protected in the triumphant Buddhist wire drawing of optical fiber cable axially be tiled in the tailstock right-hand member, with rearmounted sleeve set on tailstock, and to rearmounted sleeve covers have triumphant Buddhist wire drawing protect hair section pincers tight after, make optical fiber connect the hollow bulb of tailstock, after passing the optic fibre hole that optical fiber is established in contact pin, the tail cover is sleeved on the rearmounted sleeve, plug dust cap, finish the assembling of this connector.
Above content is preferred embodiment of the present utility model, for those skilled in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
