Description

Technical Field

[0002] Fiber optic patch panels are used as wiring connection equipment between optical cables and communication equipment, and are mainly used in optical fiber communication rooms. Fiber optic patch panels have the functions of fixing and protecting optical cables, terminating optical cables, and adjusting lines, and are an indispensable part of information rooms. Fiber optic patch panels include a storage shell and a fiber optic patch tray. The storage shell is provided with a storage cavity, and the fiber optic patch tray is slidably arranged on the wall of the storage cavity.

[0003] At present, when the optical fiber contacts the line interface on the distribution frame, the optical fiber itself has a certain gravity.

Under the action of their own gravity, a certain dragging pressure is generated on the joints, which can easily cause deformation of the lines at the joints. With the long-term transmission of the optical fiber, the dragging pressure formed by the optical fiber line itself can easily cause the optical fiber joint and the line interface on the distribution frame to be offset, affecting the normal use of the optical fiber.

At the same time, when the lower pressing seat 44 moves downward, the lower pressing plate 46 is driven to move downward through the connecting block 48, and the lower pressing plate 46 moves downward to drive the pressing column 47 to move downward, so that the pressing column 47 moves downward through the through hole 422 and inserts into the positioning hole 412, thereby realizing the fixing of the movable frame seat 42 on the limiting plate 411. The supporting seat 43 and the lower pressing seat 44 cooperate with each other to support and fix the optical fiber connector, which can improve the stability of the connection between the optical fiber connector and the line interface 21, and effectively avoid the deviation between the optical fiber connector and the line interface 21.
