Specific embodiment

For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed Illustrate specific embodiment of the present utility model.

Fig. 1 is schematic diagram of the MPO optical fiber connector provided by the utility model under discrete state.Fig. 2 is that this is practical new The decomposition diagram of the female for the MPO optical fiber connector that type provides.As shown in Figures 1 and 2, MPO optical fiber connector is mainly wrapped Include male plug 1A, female 1B and adapter 6.Male plug 1A and female 1B mainly by connection shell 2, shield 3, lasso 4, Fiber optic cable 5 and optical fiber 5a are constituted.Shell 2 is connected to be used to cooperate adapter 6 and realize the connection of male plug 1A Yu female 1B. Shield 3 is to connect the enclosure portion that optical fiber 5a is covered on rear side of shell 2, forms the structure connecting with fiber optic cable 5.It is inserted at one In head, optical fiber 5a made of multiple optical fiber monomers are twisted in lasso 4 is formed separately multifiber monomer, and optical fiber monomer extends to set It encloses 4 front end and forms contact jaw 5b, in order to contact with each other and connect with the contact jaw 5b of another plug.It needs to illustrate Being, although only showing the contact jaw 5b of row's optical fiber monomer in figure, can be two rows of optical fiber monomers in the present embodiment, corresponding Ground can be two rows of contact jaw 5b, for example, can be the optical fiber of two rows of 12 cores, i.e. the optical fiber of 24 cores in total.

More specifically, connection shell 2 and shield 3 constitute lasso shell, lasso 4 is contained in lasso shell, and lasso 4 can It is inserted into and keeps the optical fiber 5a of fiber optic cable 5.

On the other hand, 6 two sides of adapter are equipped with embedded hole (unmarked), are inserted into for male plug 1A and female 1B, public It is adapted device 6 after plug 1A and female 1B insertion and is connected and fixed, so that the front end face face of the lasso 4 of two sides and connecting Come, thus the contact jaw 5b at both ends is contacted with each other and connected.In the present embodiment, adapter 6 and male plug 1A and female The connection of 1B can by be set to connection 2 outer surface of shell convex ribs and the inner surface for the embedded hole for being set to adapter 6 it is recessed It is mutually fitted into and realizes between slot.

According to MPO optical fiber connector provided by the utility model, by the fitting connection structure of above-mentioned convex ribs and groove, one Aspect, due to convex ribs with groove it is chimeric be it is a kind of compared with the structure that consolidates, it is thus possible to limit male plug and female and connecting Movement laterally or longitudinally occurs after getting up；Further, due to male plug and female after connecting laterally or Longitudinal movement is limited, it is thus possible to further increase the precision of optical fiber align.

In addition, one is provided with pilot pin 7 in male plug 1A and female 1B, another one is provided with location hole 8, by fixed The position alignment insertion location hole 8 of needle 7 can further improve the precision of optical fiber align.

As shown in Fig. 2, in male plug 1A or female 1B spring can be configured across gasket 9 in the rear side of lasso 4 10, it is exerted a force via gasket 9 to lasso 4 by spring 10, so that the combination of the lasso 4 of two sides is even closer.

Chimeric company in order to further increase the stability of connection, relative to Fig. 1 and convex ribs employed in figure 2 and groove It connects, in the present embodiment, as shown in figure 3, forming latch arms 2a, the door bolt on the connection shell 2 of male plug 1A or female 1B Hammerlock 2a is chimeric with the latch hole 6a on adapter 6 and forms robust structure.Latch arms 2a can be integrally formed at connection shell 2 On, and there is elasticity, in order to produce and install.It should be noted that not showing that convex ribs in Fig. 1 and Fig. 2/recessed in Fig. 3 Slot structure, it is to be understood that the design in Fig. 3 can have convex ribs/groove structure simultaneously or not have convex ribs/groove knot Structure.

The embodiments of the present invention are described above in conjunction with attached drawing, but the utility model is not limited to The specific embodiment stated, the above mentioned embodiment is only schematical, rather than restrictive, this field it is common Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model Under, many forms can be also made, these are belonged within the protection of the utility model.
