Problems solved by technology
[0003] In the power system optical communication network, often accompanied by equipment aging transformation, large-scale technical transformation, regular maintenance, and sudden fault handling, etc., the ODF will be opened repeatedly, and fiber jumping and other work will be repeated. Because the ODF body is too heavy , forming a cantilever beam structure, causing the far end of the ODF to fall off the corner during the rotation process and it is difficult to avoid it effectively, so it is not easy to install the ODF into the ODF cabinet, thereby reducing the efficiency of operating the ODF and making the optical fiber communication easily affected

Embodiment Construction
[0038] In order to better understand the ODF cabinet provided by the embodiment of the present invention, the structure of the optical fiber cable network applied to the ODF cabinet is firstly described as follows:
[0039] The optical fiber cable network may include at least two node devices, such as an optical distribution frame ODF or an optical fiber distribution terminal FDT. For example, if figure 1 The fiber optic cable network shown includes an ODF and n (n≤8 and a positive integer) FDTs. These node devices are connected in series via optical cables to form a ring-shaped fiber optic cable network. The cable between two node devices is called a cable segment, and the node The device provides space for termination and splicing of the optical fibers in the cable section. For example, the shared fiber can be terminated in each node device, while the exclusive fiber can be terminated in only one intermediate node device (FDT), and the other fibers in the cable segment, exc...

The embodiment of the present invention discloses an optical fiber distribution frame cabinet, which includes a cabinet, and a plurality of optical fiber distribution frames are installed in the cabinet, and the optical fiber distribution frame includes a fixed part and a rotating part connected to each other. The first side of the fixed part is fixedly connected with the cabinet, the end face of the second end of the optical fiber distribution frame is concavely provided with a sliding groove, the end face of the cabinet is provided with a hanging ear part, and the hanging ear part It is protrudingly arranged in the direction toward the optical distribution frame, and when the lug-hanging part is inserted into the sliding groove, the lug-hanging part slides along the guide of the sliding groove until the The optical fiber distribution frame is installed inside the cabinet. The optical fiber distribution frame shown in this embodiment cooperates with the hanging ear parts of the optical fiber distribution frame cabinet by providing a sliding groove with a slope feature, which effectively avoids the occurrence of falling during the installation of the optical fiber distribution frame. The angle phenomenon improves the installation efficiency of the optical fiber distribution frame.
Description
technical field [0001] The present application relates to the field of optical fiber communication, in particular to an optical fiber distribution frame. Background technique [0002] In the field of communication, optical fiber is an indispensable carrier for optical communication transmission network channels, and optical distribution frame (ODF) is an optical fiber communication network terminal and relay site to realize fiber arrangement, fiber jumping and access Functionally essential equipment. [0003] In the power system optical communication network, often accompanied by equipment aging transformation, large-scale technical transformation, regular maintenance, and sudden fault handling, etc., the ODF will be opened repeatedly, and fiber jumping and other work will be repeated. Because the ODF body is too heavy , forming a cantilever beam structure, causing the far end of the ODF to fall off during the rotation process and difficult to avoid effectively, it is not e...
