The optical cable distribution box is an indoor and outdoor optical node product commonly used in FTTH-ODN networks, and is an interface device for connecting a trunk optical cable and a distribution optical cable outdoors, in a corridor or indoors. For example, the optical cable fiber distribution box is used for realizing connection with the household butterfly-shaped optical cable through the optical splitter after the wiring optical cable is connected, and the functions of welding, drawing and splitting the optical cable are completed in the optical cable fiber distribution box. Because the optical cable fiber dividing box is an outdoor device, the optical cable fiber dividing box is required to resist to severe weather and severe working environment, and has the characteristics of water vapor condensation prevention, water resistance, dust prevention, insect damage prevention, rat damage prevention and strong impact damage resistance.

The conventional optical cable fiber dividing box has the following problems:

1) The waterproof optical cable fiber distribution box assembly only considers that the shell is waterproof and does not consider that the splitter box is waterproof, so that the service life of the splitter is greatly reduced, and in some cases, the splitter box is required to be arranged inside the fiber distribution box assembly, and constructors are required to perform optical fiber connection operation inside the box body.

2) The optical cable fiber splitting box component is free of an independent splitter box, the optical splitters are directly exposed in the environment, and the splitters are easily damaged when the trunk optical cables are laid out in a cover opening state; meanwhile, the optical fiber of the splitter can only present a 'complex space curve' state, the site construction is complex, the installation effect is difficult to ensure, and the performance (insertion loss and return loss) of the splitter is influenced.

Therefore, it is necessary to design an end-face waterproof optical splitter module box and a waterproof optical cable distribution box assembly to overcome the above problems.

The application provides an optical divider module box, which comprises a box body and an optical divider arranged in the box body, wherein the optical divider comprises an input end and an output end, a first adapter is arranged at one end of the box body, and the output end of the optical divider is connected with the first adapter; the other end of the box body is provided with an input port, and the input port is used for leading out the input end of the optical splitter; the first adapter is fixed with the first fixed position and is sealed with the box body through a first sealing ring.

The application further provides an optical cable splitting box, which comprises the optical splitter module box.

The optical divider module box provided by the disclosure is arranged in the box body and is connected with an output end adapter on the box body through a sealing ring so as to be led out, so that the output port of the optical divider is waterproof, and the operation of constructors outside the box body is facilitated.

The optical cable fiber distribution box provided by the disclosure can realize preassembling and field installation/replacement by arranging the independent optical splitter module box, is convenient to operate and improves the efficiency.

In at least some examples, the optical splitter module box and the optical cable distribution box provided by the disclosure can reach an IP68 waterproof level, so that the reliability of the product applied in an outdoor environment is further improved.

For example, the fixing portion 51 may be implemented as a snap or screw, etc. to be fixed with the first adapter 22 by the snap or screw, etc.

The disclosed embodiments are not limited in terms of the type of adapter, and may be, for example, a conventional standard SC adapter, or other type of adapter.

The embodiment of the present disclosure is not limited to the mounting form between the first adapter 22 and the case 21. For example, the first adapter 22 may be secured to the securing location 51 of the case 21 by a screw connection, snap connection, welding, adhesive, or the like.

As shown in fig. 2B, the optical splitter module box 2 further includes a first sealing ring 223, for example, disposed on the first adapter 22, and the first adapter 22 is sealed with the box body 21 by the first sealing ring 223, so as to improve the end face waterproof performance of the optical splitter module box. The first seal ring 223 surrounds the first adapter 22 and engages the wall or end face of the mounting hole 50 to effect a seal. For example, a clamping groove surrounding the adapter body is provided on the first adapter 22 to fix the first sealing ring 223.

The optical splitter module box 2 provided by the embodiment of the disclosure can be used alone or integrated with other functional boxes to meet the requirements of different installation environments and users.

As shown in fig. 1B, for example, a wall-hanging mounting hole 53 may be provided on the case 21 (e.g., the second housing 24) for wall-hanging mounting of the case. For example, the cassette 21 may be provided with a securing structure 54 for mounting and securing with other functional enclosures, such as a fiber optic cable distribution box. For example, the fixing means may be a snap-fit fixing or a screw-fit fixing. For example, the securing structure 54 may be a clasp. For example, as shown in FIG. 1B, a groove 210 may be provided around the case 21 to provide a seal ring to facilitate sealing of the case to other functional cases when mounted thereto, as will be described in more detail below.

At least one embodiment of the present disclosure further includes a fiber optic cable functional box including the optical splitter module box 2 provided in any one of the above embodiments. The present disclosure is exemplified with the fiber optic cable functional box as a fiber optic cable distribution box, however, this is not a limitation of the present disclosure.

For example, as shown in fig. 5A, the case 31 may be defined by an upper cover 313 and a lower cover 314, that is, include the upper cover 313 and the lower cover 314. For example, when the case is opened, the upper cover 313 may be opened by turning the cover, and the opening of the upper cover 313 does not affect the case of the optical splitter module case 2, and reference may be made to fig. 6B and 7A hereinafter. For example, the upper cover 313 is a part of the upper case 311.

For example, a plurality of identifiers 315 are provided on the upper surface of the box 31, that is, the upper surface of the upper box 311 or the upper box 313, the plurality of identifiers 315 are in one-to-one correspondence with the plurality of first adapters 22 in the optical splitter module box 2, and each identifier 315 is used for identifying the corresponding first adapter 22. For example, the identifier 315 may be the number of the corresponding first adapter 22.
