DETAILED DESCRIPTION

[0025] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0027] The present application relates to a preferred embodiment of a household small optical cable terminal box with splitting.

[0028] Please refer to Figs. 1-3 , the household small optical cable terminal box with splitting includes a detachable cover 1 and a box 2, the box 2 includes an integrally formed vertical plate 3, a bottom plate 4 and a surrounding plate 5, the vertical plate 3 is vertically arranged on one side edge of the bottom plate 4, and the surrounding plate 5 is arranged along the circumferential edge of the bottom plate and forms a containing cavity together with the vertical plate 3. This integrated structure enhances the overall strength of the box and improves the waterproof and dustproof performance.

[0029] Further, the size of the cover 1 is adapted to the size of the box 2 to ensure close fitting when they are installed. The cover 1 has side guard plates 6 on both sides which fit the box, and when the cover 1 is closed, the side guard plates 6 can completely fit the side wall of the box, further preventing external dust, water vapor and the like from entering the inside of the box.

[0030] In one exemplary embodiment, the vertical plate 3 is provided with a cable inlet hole 7 and an adapter mounting hole 8, the cable inlet hole 7 is responsible for the introduction and fixation of the optical cable, and the adapter mounting hole 8 is used for inserting the adapter 9.

[0031] Preferably, at least one cable inlet hole 7 is provided. The cable inlet hole 7 may be provided with a guide slope to facilitate the introduction of optical cable. A sealing ring may be embedded in the cable inlet hole 7 to provide sealing protection.

[0032] Preferably, the adapter mounting holes 8 are provided at least four and are distributed in a rectangular array to ensure the consistency of adapter 9 installation.

[0033] Based on the above structure, the base plate 4 integrates a splitter area and a fiber optic splice protection area. The integrated splitter can distribute the signal from the trunk fiber to multiple user lines, and the fiber optic splice protection area provides a platform for fiber optic splicing, ensuring stable and reliable splicing. In this way, the splitter and the optical cable terminal box are combined, thereby significantly reducing the equipment size and lowering costs.

[0034] Specifically, the first part is the splitter area, which has several symmetrically distributed limiting plates 12, which together form a miniature splitter slot 11 for fixing the miniature splitter 10. The miniature splitter can be used to distribute the backbone fiber optic signal to multiple user terminals to meet the requirements of branch communication links.

[0035] The width of the miniature splitter slot 11 is adapted to the width of the miniature splitter 10 housing, ensuring that the splitter fits tightly in the slot and preventing loosening or displacement. The miniature splitter 10 is fastened in the miniature splitter slot 11 by a snap-fit ​​method, enabling quick installation and removal.

[0036] Secondly, there is the fiber optic splice protection area, which has several sets of symmetrically distributed slots 13, which together form a heat shrinkable tube slot 14 for fixing the heat shrinkable tube. The slots 13 provide stable support and positioning for the heat shrinkable tube, ensuring that the heat shrinkable tube is firmly fixed in the heat shrinkable tube slot.

[0037] The width of the heat shrink tubing slot 14 is adapted to the width of the heat shrink tubing, ensuring a tight fit within the slot and preventing loosening or displacement. The heat shrink tubing is secured in the slot via a snap-fit ​​mechanism, enabling quick installation and removal.

[0038] The depth of the heat shrinkable tube groove 14 is 4~8mm, and the interval between adjacent groove plates 13 is 2.0~3.0mm, which can accommodate heat shrinkable tubes of different diameters.

[0039] The groove plate 13 is an elastic plate, which can provide a certain elastic buffer to avoid excessive stress on the heat shrinkable tube during installation or use. The elastic plate can also provide a certain degree of self-adaptability when the heat shrinkable tube is installed to ensure a tight fit between the groove and the heat shrinkable tube.

[0040] The working principle of this utility model of a small household optical fiber terminal box with beam splitter is as follows:

[0041] The micro shunt 10 is clamped in the micro shunt slot 11 formed by the limiting plate, and the adapter 9 is clamped in the adapter mounting hole 8,

[0042] The main cable is introduced into the terminal box from the outside through the cable inlet hole 7, and first enters the heat shrink protection tube clamping groove 14, and under the protection of the heat shrink protection tube, the incoming end of the main cable is fused with the incoming end of the micro shunt 10, realizing the transmission of optical signals from the main cable to the micro shunt 10.

[0043] The branched optical fibers pass through the adapter 9 in turn, realizing further connection with the external optical fiber communication system.

[0044] The household small optical cable terminal box with splitting has the beneficial effects that:

[0045] Increase the splitting function: on the basis of the traditional optical cable terminal box, the splitting function is added, so that the device size and cost are reduced;

[0046] The main optical fiber signal can be distributed to multiple branch optical fibers, meeting the branch communication link demand condition, meeting the communication demand of different rooms or devices in the home, and realizing flexible distribution of optical signals;

[0047] The clamping type adapter is adopted, the installation process is simplified, the production cost is greatly reduced, the assembly of the terminal box is more convenient, the device stability and reliability are improved, and the maintenance cost is reduced.

[0048] The heat shrink protection tube clamping groove is added in the optical fiber fusion protection area, the heat shrink protection tube is directly fixed, the traditional fiber fusion disc is omitted, and the equipment cost is further reduced.

[0049] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion according to the content of the utility model specification, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
