Embodiment two:
With reference to fig. 2 and 3, the biggest difference between the present invention and the conventional optical fiber distribution frame is the movable connector 4, and the optical fiber 3 is mounted on the movable connector 4 according to fig. 2.
The movable connector can automatically adjust the length of the optical fiber according to the position of the fiber box, so that the fiber box can be smoothly put in and pulled out of the shell.
The movable connector consists of a cylinder 5, a cylinder 6, a spring and a connecting rod, wherein the cylinder 5 is connected with the cylinder 6, the cylinder 5 is connected with the cylinder 7 through the connecting rod, the cylinders 5 and 6 are fixed, and the cylinder 7 is movable. The connecting rod 1 is arranged between the cylinders 5 and 6, the connecting rod 2 is arranged between the cylinders 5 and 7, and the connecting rods 1 and 2 are connected by springs.
