When the rack is used for arranging the cable and the concave winding at the bottom of the cat, the cable needs to be wound, and the tail part adopts a connector with a straight-through structure, so that the cable which needs to be bent is easy to damage.
The tail adjusting structure comprises a middle shell, a rotating piece and a fixing cap which are sequentially connected.
The middle shell is coaxially arranged at the tail end of the connector, specifically, the middle shell can be integrally formed with the connector, and can also be fixedly connected with the connector by adopting a fixing structure, so long as the coaxial arrangement of the middle shell and the connector is met.
In order to solve the problem that the existing connector is easy to damage the optical cable to be bent, the present embodiment provides a technical solution that the rotating member is rotatably disposed at the end of the middle shell along a rotating shaft, and the rotating shaft is perpendicular to the middle shell
Is defined by a plane perpendicular to the axis of the mold. After the optical cable 21 is installed, the optical cable is led out from the tail end of the rotating part, the optical cable is bent at an included angle with the axial direction of the connector through the rotation of the rotating part, after the connector is inserted into the optical fiber adapter, the optical cable is abutted to generate a backspacing distance under the action of the pressure of the ceramic ferrule, so that the optical cable is slightly bent, and meanwhile, the optical cable can be bent in a follow-up manner by matching with the technical scheme provided by the embodiment, and the connection performance of the optical cable is not influenced.
In order to lock the rotating member and the middle shell at a certain included angle, and further enable the optical cable 21 to be led out at a fixed included angle according to the requirement of the docking site, a fixing cap is further provided in this embodiment, and the fixing cap is disposed at the tail end of the rotating member and locks the rotating member and the middle shell at a certain included angle. In the implementation process of bending the optical cable 21, since the optical cable 21 needs to be led out from the middle position of the middle shell, the setting position of the rotating shaft between the middle shell and the rotating member needs to be designed on the outer side surface of the middle shell, in this embodiment, the outer side surface of the middle shell is in an axisymmetric structure, the first rotating structures are respectively arranged on the symmetric outer side surfaces, and the connecting line between the two first rotating structures forms the rotating shaft of the rotating member. One end of the rotating piece, which is rotationally connected with the middle shell, is of a double-fork arm structure, a second rotating structure matched with the first rotating structure is arranged on the double-fork arm structure, and specifically, the double-fork arm of the rotating piece is rotationally arranged on the two symmetrical outer side surfaces of the middle shell through two groups of rotating structures.
The invention also provides a connecting device, which comprises a first connector and a second connector, wherein at least one of the first connector and the second connector is the multi-core optical fiber connector of any embodiment, and the first connector and the second connector are detachably connected.
In this embodiment, the connecting device of the present invention uses the multi-core optical fiber connector, so that when the optical fibers 100 are butt-coupled, the optical fibers 100 will bend due to the interference fit back, and the end surfaces of the optical fibers 100 are coupled more tightly by using the resilience force of the optical fibers 100, so that the optical transmission signals are stably transmitted, and the transmission efficiency is improved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing disclosure is illustrative of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
