Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a sealed cross-connection box. Background Art

[0002] A sealed cross-connect box is a device used in a fiber optic communication network to provide switching, connection, distribution and protection of optical fibers. While existing sealed cross-connect boxes can basically meet daily usage requirements, there are still some shortcomings that need to be improved.

[0003] When connecting optical fibers, the widely used fixed-sealed cross-connection boxes on the market insert the optical fibers into the device from the opening at the bottom of the device and then connect the optical fibers to the internal connection modules. However, since the optical fiber group is not fixed at the bottom of the interconnection box, once the optical fibers are touched by external force, they are prone to fall off between the optical fibers and the interconnection box. Therefore, we propose a fixed-sealed cross-connection box to solve the above problem. Utility Model Content

[0006] As a further preferred embodiment of the present technical solution, the auxiliary locking assembly includes a guide slide rod, a side plate, a slide plate, a push block, a positioning column, a positioning hole and a return spring. A group of the movable splints has a guide slide rod fixed to the right outer wall, a side plate is fixed to the right side of the guide slide rod, a slide plate is arranged outside the guide slide rod, a positioning hole is opened at the end of the slide plate, a push block is fixed to the side wall of the slide plate, and another group of the movable splints has a positioning column fixed to the right side, the positioning hole on the slide plate can be sleeved on the outside of the positioning column, and a return spring is wound around the outside of the guide slide rod.

[0011] The utility model provides a sealed cross-connection box, which has the following beneficial effects:

[0012] 1.

[0013] 2. The utility model installs a movable slide plate on the side end of the movable splint. When the two sets of movable splints are moved together, the push block on the surface of the slide plate can be pulled to allow the slide plate to move along the surface of the guide slide rod and squeeze the reset spring. Then, the slide plate is rotated to drive the positioning hole to rotate to the outside of the positioning column, and the force on the slide plate is released, so that the slide plate can drive the positioning hole to quickly cover the surface of the positioning column under the elastic force of the reset spring, thereby effectively preventing the two sets of movable splints from opening accidentally and improving the stability during use.
