[0002] With the rapid development of fiber-optic communication technology, fiber optic distribution boxes have become a crucial component of fiber optic networks, used for connecting, distributing, and managing optical fibers. Existing fiber optic distribution boxes use fusion splicing to secure optical fibers, resulting in poor scalability and difficulty adapting to the needs of fiber optic networks of varying scale and complexity. Furthermore, redundant links are required to prevent unavailability in the event of fiber failure, leading to a complex and bulky distribution box structure. Summary of the Invention

[0003] The problem solved by the present invention is that the optical fibers are fixed by fusion splicing, which has poor scalability and requires the provision of redundant links, resulting in a complex link structure and a large volume of the distribution box.

[0004] In order to solve the above problems, the present invention provides a non-fusion-splice and non-redundancy fiber optic distribution box, which comprises: an outer shell, the outer shell is provided with a pull-out slot, one side of the pull-out slot has an opening, and the other side opposite to the opening is provided with a buffer; a pull-out box and an optical fiber, the optical fiber is arranged in the pull-out box, the pull-out box slides in the pull-out slot and can at least partially slide out from the opening; the pull-out box has a connector fixing groove at one end facing the buffer, the end of the optical fiber is connected to a fiber optic connector, and the fiber optic connector is fixed to the connector fixing groove; an optical fiber adapter, the optical fiber adapter is plugged into the optical fiber connector, support plates are provided on both sides of the optical fiber adapter, and the support plates abut against the buffer; a pigtail connector, the pigtail connector is plugged into the other end of the optical fiber adapter opposite to the optical fiber connector.

[0005] The technical effects achieved after adopting this technical solution are as follows: the pull-out box is used to store optical fibers, thereby saving space while ensuring the length of the optical fibers; after the pull-out box is pulled out from the pull-out slot, it is convenient to manually store the optical fibers; the connector fixing slot positions the optical fibers in the width direction, and the optical fibers are separated from the optical fiber adapter when the pull-out box is pulled out. When the pull-out box is put back, the optical fiber connectors can be accurately re-connected through the positioning of the pull-out slot, thereby avoiding damage to the optical fibers; the connection method of the optical fiber adapters makes the optical fibers more scalable, and they are redundant with each other, without the need to set up additional redundant links, so the structure of the non-fusion-free and non-redundant optical fiber distribution box is simpler and smaller in size; when the optical fiber connector and the optical fiber adapter are connected, the buffer can buffer the optical fiber adapter, thereby further protecting the optical fiber connector, the optical fiber adapter and the pigtail connector.

[0006] Furthermore, the fusion-free and redundancy-free optical fiber distribution box further comprises: at least one winding post, the winding post is rotatably connected to the inner bottom plate of the pull-out box, and the optical fiber is wound around the winding post.

[0008] Furthermore, a stopper is provided at one end of the cable winding post away from the inner bottom plate for stopping the optical fiber; wherein the cable winding post is detachably connected to the pull-out box.

[0009] The technical effect achieved after adopting this technical solution is: the stopper is used to prevent the optical fiber from warping, so that the optical fiber can be stably wound around the side of the winding column; the winding column is detachable, which is convenient for winding the optical fiber with the stopper.

[0010] Furthermore, the optical fiber connector has a limiting widening portion at one end close to the optical fiber; the connector fixing groove includes: an optical fiber card slot and a limiting card slot, the optical fiber is located in the optical fiber card slot, the limiting widening portion is fixed to the limiting card slot, and the width of the limiting card slot is greater than that of the optical fiber card slot.

[0011] The technical effect achieved after adopting this technical solution is: part of the optical fiber is fixed by the optical fiber card slot, and then the limiting widening part is limited by the limiting card slot valley bottom function, so that the connection between the optical fiber and the limiting widening part will not bend; after the limiting widening part is fixed, pulling the optical fiber will not cause the limiting widening part to enter the pull-out box, thereby facilitating the pulling out of the optical fiber.

[0012] Furthermore, the fiber optic adapter includes a fiber optic interface and a pigtail interface, and a coupling hole is connected between the fiber optic interface and the pigtail interface; the fiber optic interface is used to connect the fiber optic connector, and the pigtail interface is used to connect the pigtail connector.

[0015] The technical effect achieved after adopting this technical solution is: when the fiber optic connector is installed into the fiber optic interface, the connector buckle also enters the fiber optic interface. The connector buckle is gradually tightened by the buckle slide groove until the positions of the locking protrusion and the locking groove correspond.
