Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides an embodiment:
the utility model provides a two core multimode fiber coupler, including coupler main part 1 and two core optic fibre 13, first spout 2 has transversely been seted up on the top of coupler main part 1, there is safety cover 3 inside of first spout 2 through slider movable mounting, connecting groove 4 has been seted up on 3 tops of safety cover, the positive fixed mounting of safety cover 3 has go-between 5, the bottom fixed mounting of go-between 5 has axis of rotation 12, the quantity of axis of rotation 12 is 4, the equal fixed mounting in both sides of coupler main part 1 has solid fixed valve 11, axis of rotation 12 and solid fixed valve 11 mutually support.
Connecting groove 4 has been seted up on 3 tops of safety cover, and the front fixed mounting of safety cover 3 has go-between 5, and safety cover 3 and go-between 5 mutually support and have formed the meshing structure, and when connecting groove 4 and go-between 5 mutually supported the use, go-between 5 and safety cover 3 also can slide, in the use, greatly increased the fault tolerance of device.
The left end fixed mounting of coupler main part 1 has connector 6, the one end hinge of connector 6 articulates there is connecting valve 7, dustproof stopper 8 has been seted up in connecting valve 7's front, the connecting valve 7 of installing connector 6 is closed, insert dustproof stopper 8 and protect in connector 6 is inside, make dustproof stopper 8 just insert inside connector 6, make it protect inside, better when using provide life, greatly increased at life.
The front of coupler main part 1 has been seted up second spout 9, and the inside of second spout 9 is connected with go-between 5 through slider 10, and go-between 5 and second spout 9 mutually support and have formed sliding construction, through mutually supporting between go-between 5 and the second spout 9, can also take place simple translation with whole coupler main part 1 when fixed, greatly increased the stability of device when using.
