Description

Technical Field

[0001] The utility model relates to the technical field of terminal box installation, in particular to a terminal box installation frame. Background Art

[0002] Fiber optic is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light". The fiber optic terminal box is the terminal of an optical cable. One end of it is the optical cable and the other end is the pigtail. It is equivalent to a device that splits an optical cable into single optical fibers. The user optical cable terminal box installed on the wall provides the fusion of optical fibers, the fusion of optical fibers and pigtails, and the connection of optical connectors.

[0003] The terminal box is where the end of the optical cable is connected, and then connected to the optical switch through an optical jumper. Therefore, the terminal box is usually installed on a 19-inch rack and can accommodate a large number of optical cable ends. The terminal box connects the optical cable to the pigtail for protection, and the shell of the terminal box should be easy to open and install. The shell should have a lead-out device for high-voltage protection grounding of the optical cable metal components. In the terminal box in the prior art, since the optical fiber is inside the drawer and installed on the rack, the space reserved for the rack is large during use, which is inconvenient.

[0004] Utility model patent CN219085187U discloses a fiber optic terminal box mounting bracket, which facilitates the installation of the mounting bracket and base bodies of different lengths by adding a slide rail on the mounting base, increases the flexibility of the mounting bracket length adjustment, and improves the length adjustment effect of the mounting bracket.

[0005] However, the equipment adjustment and installation structure are too complicated, the installation adjustment is too cumbersome, and this installation method makes the external optical fiber more messy when the optical fiber is plugged into the upper port. At the same time, this installation method, when the base body is placed horizontally, the terminal box is located under the base body, which is inconvenient to open the terminal box, and it will also increase a certain burden during maintenance. Utility Model Content

[0014] Preferably, an opening adapted to the long strip through slot is provided on the right side of the slot, and the opening is communicated with the long strip through slot.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model provides a terminal box installation frame. During installation, the slot is rotated along the hinged position until it abuts against the limit support block. At this time, one side of the terminal box port insertion position is inserted into the slot, and the port is just located in the long strip through slot. Then, the terminal box drives the slot to rotate along the hinged position to a vertical state, and the fixing frame is pulled down until the limit slider abuts against the bottom of the limit slide slot. At this time, the fixing frame is sleeved on the periphery of the terminal box, and then the clamping block is clamped to the right to clamp the left side of the terminal box to fix it by turning the knob, thereby completing the installation. It is convenient and quick, and close to the wall, greatly saving installation space.

[0017] When performing maintenance and disassembly, the knob is turned out until the clamping block is separated from the side wall of the terminal box, and it is slid upward until the first magnet and the second magnet are attracted, and then the terminal box and the slot are rotated along the hinge to an angle that is convenient for taking out the terminal box. At the same time, an opening connected to the long strip through slot is provided, so that the terminal box can be taken out of the slot for maintenance without unplugging the optical fiber, avoiding the need to pull out the optical fibers one by one during maintenance, which affects the disassembly efficiency.
