[0044] Effect: It provides a channel for optical cables and wires to enter and exit the box 1, and through the connection with the matrix arrangement hole 19, the wires can be orderly distributed to each electrical device on the mounting plate 7 after entering the box 1, avoiding the confusion and entanglement of the wires, facilitating the connection, management and maintenance of the line, improving the work efficiency, and also reducing the signal interference and safety hazards caused by the confusion of the wires.

[0045] The working principle of the outdoor optical cable distribution box is as follows:

[0046] The box 1 provides protection and installation foundation for the entire device. When the internal devices need to be operated, the cabinet door 2 can be opened through the key lock 3. During operation, the heat generated by the internal electrical devices is exhausted by the cooling fan 17, and at the same time, the external cold air enters the box through the cooling slot 4 on the side of the box 1, forming air circulation and accelerating heat dissipation. The electrical devices installed in the box 1 are fixed on the mounting plate 7 by the double mounting strip 5 and the fixing block 6, and the electrical device mounting hole 8 on the mounting plate 7 ensures stable installation and convenient wiring. The overhead chassis 9 avoids moisture in the box 1, and the positioning ears 11 in the sliding shells 10 on both sides can fix the box 1 to the ground or mounting seat through the positioning holes 12, ensuring stable installation. The top hat 13 is located at the top of the box 1 under the support of the spring column 16, and its edge flow guide groove 15 and partition block 14 guide the rainwater to flow out to both sides, preventing rainwater from seeping in.

[0047] As shown in Figure 1 In some embodiments, the fixing block 6 is bolted through the connection hole on the double mounting strip 5, and the connection hole is arranged in a matrix. The double mounting strip 5 provides a solid support foundation for the mounting plate 7, ensuring that the mounting plate 7 can stably bear various electrical devices inside the box 1.

[0048] As Figure 1 shown, in some embodiments, at least four positioning holes 12 are symmetrically arranged on the positioning ears 11 for connecting and fixing to the ground or mounting seat; the design of multiple positioning points enables the fiber distribution box to be more stably fixed in the mounting position after installation, effectively resisting external forces from different directions.

[0049] As Figure 1 shown, in some embodiments, the partition block 14 is used to form a flow guide shape, so that the rain flows to both sides; its main function is to guide the rain to flow in the designed direction to both sides when the rain falls on the top hat 13 on rainy days. This can avoid the accumulation of rainwater on the top hat 13 to form a water pit, prevent the accumulated water from penetrating into the box 1 through the gap between the top hat 13 and the box 1, thereby effectively protecting the electrical devices in the box 1 from rainwater erosion and ensuring the normal operation of the electrical devices.

[0050] As Figure 4 shown, in some embodiments, the area of the top hat 13 is larger than that of the box 1, and a plurality of flow guide grooves 15 are arranged at the edge; the top hat 13 has an area larger than that of the box 1, which can provide more comprehensive protection for the top of the box 1. In rainy days, it can effectively prevent rainwater from directly falling on the top of the box 1, reduce the risk of rainwater penetration, and facilitate heat dissipation.

[0051] As Figure 3 shown, in some embodiments, the wire inlet and outlet hole 18 is connected to the matrix arrangement hole 19 at the bottom of the box 1 to the mounting plate 7 inside the box 1; the wire inlet and outlet hole 18 provides a channel for the optical cable and the wire to enter and exit the box 1, and its design of being connected to the matrix arrangement hole 19 at the bottom of the box 1 to the mounting plate 7 realizes the orderly management of the wire.

[0052] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features.
