Description
Technical field
The utility model relates to joints of optical fibre technical field, relates in particular to a kind of MPO type fiber active linker that many parallel optical fibres are linked to each other.
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.
Realize the fiber active linker that many parallel optical fibres link to each other, its structure more complicated, and it is had relatively high expectations, wherein topmost be exactly optical fiber when connecting fiber orientation and connect after reliability, the polarization of present existing fiber active linker and reliability are not very desirable.
The utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of can realize that many parallel optical fibres link to each other and the location is better, the higher MPO type fiber active linker of reliability, and it is simple in structure, and low cost of manufacture is easy to use.
For achieving the above object, fiber active linker of the present utility model, comprise connecting link, spring, connector, tail cover, shell, be provided with many parallel optic fibre holes in the described connector, connecting link middle part body is provided with fixture block, outer casing inner wall is provided with and the fixture block corresponding grooves, and described connecting link clamps the location in the enclosure by fixture block and groove; The shell front inner wall is provided with limited block, and on limited block, the other end and spring left end cooperate and link to each other described connector in its optic fibre hole one end overhead, described spring right-hand member overhead the connecting link left end offer uncovered in.
As the improvement of aforesaid way, be provided with the cushion block of hollow at the connector right-hand member, described spring left end overhead is on cushion block.
As the further improvement of aforesaid way, be provided with the protective sleeve that has through hole in cushion block hollow inside.
In addition, be set with clip at the connecting link afterbody, described tail cover is sleeved on the clip.
Front end sleeve at shell is equipped with dust cap.
Adopted technique scheme, in use,, made the main body of this connector accurate, effectively prevented the generation of obscission in the enclosure location owing to adopted the locating device of limited block and fixture block; Cushion block is set, prevents from that spring from directly contacting with connector and spring takes place to head in the connector, locate more accurate; Add protective sleeve, realize preposition combing, optical fiber can be inserted in the optic fibre hole more accurately many parallel optical fibres; Add dust cap, prevent that lock pin is infected with dust, it is simple in structure, 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
