Description

Technical Field

[0001] This utility model relates to the field of optical splitter technology, and in particular to an integrated enclosure for a wall-mounted optical splitter. Background Technology

[0002] Optical splitters are important passive devices in fiber optic links. They can split a single optical signal into multiple paths according to a certain ratio, or vice versa, combine multiple optical signals into a single path. Common types include fused biconical taper (FBT) and planar waveguide (BBT) types. They are widely used in fiber optic communication, cable television networks, and fiber-to-the-home (FTTH) scenarios. In FTTH, they can distribute the backbone fiber optic signal of the operator to each user terminal, achieving efficient signal distribution. Optical splitters have advantages such as uniform splitting, low insertion loss, high reliability, and no need for power supply, which greatly reduces the construction and operation costs of fiber optic networks.

[0003] A search revealed Chinese Patent Publication No. CN202372677U, which discloses a wall-mounted integrated optical splitter enclosure, comprising an enclosure unit and a cover unit. The enclosure unit comprises an assembly unit, a fiber optic cable tray unit, an optical splitter unit, a housing unit, an optical cable entry unit, a drop cable exit unit, and a locking and positioning device. The assembly unit includes an assembly unit hinge device, a prefabricated mounting device arranged in a rectangular array, a pole mounting device, an anti-theft device, an assembly unit hinge mounting device, and an assembly unit sealing device. The cover unit is used to cover the enclosure unit and includes a cover door lock, a locking device, a cover unit sealing device, and a cover unit hinge device. This utility model has the advantages of being flame-retardant, dustproof, waterproof, UV-resistant, small in size, compact in structure, widely applicable, easy to install, and having a reasonable load-bearing space. However, the above structure does not take into account that the barrier plate can only block the terminal block but cannot seal it. As a result, during use, moisture and dust in the air can still adhere to the connection between the terminal block and the wire, which may cause a short circuit. The actual use effect is not ideal. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wall-mounted integrated optical splitter enclosure, which aims to improve the existing technology where the barrier plate can only block the terminal block but cannot seal it. This will cause moisture and dust in the air to still adhere to the connection between the terminal block and the wire during use, thus causing a short circuit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wall-mounted integrated optical splitter housing, comprising an outer shell, an optical splitter disposed on the inner wall of the outer shell, multiple terminal blocks disposed on the outer wall of the optical splitter, a fixing cover fixedly connected to the lower part of the outer wall of the optical splitter, a notch one being provided on the outer wall of the fixing cover, a positioning groove being provided in the upper middle part of the outer wall of the optical splitter, a top cover being engaged with the inner wall of the positioning groove, a hook being fixedly connected to the inner wall of the top cover, a second notch two being provided on the bottom surface of the top cover, a rubber block being engaged between the outer wall of the first notch and the inner wall of the second notch, a wire through hole being provided in the middle of the rubber block, and a suspension mechanism being provided on the outer wall of the outer shell for suspending the equipment.

[0006] Through the above technical solution: the outer casing can effectively resist the influence of external environmental factors on the internal equipment. An optical splitter is installed on the inner wall of the casing, undertaking the crucial task of distributing optical signals. Multiple terminals are evenly distributed on the outer wall, providing reliable connection points for optical signal input and output, ensuring the stability and accuracy of signal transmission. A fixing cover is fixedly connected to the lower part of the outer wall of the optical splitter. The design of the fixing cover aims to further protect the lower area of ​​the optical splitter. A notch is provided on the outer wall of the fixing cover. A precisely machined positioning groove is provided in the upper middle part of the outer wall of the optical splitter. The positioning groove is used to achieve precise engagement with the upper cover. The upper cover engages with the positioning groove... The cover fits snugly and securely covers the upper part of the optical splitter. Hooks are fixedly connected to the inner wall of the cover, further enhancing the stability of the connection between the cover and the enclosure. A second notch is provided on the bottom surface of the cover, corresponding to a first notch on the outer wall of the fixing cover. A rubber block is tightly fitted between the outer wall of the first notch and the inner wall of the second notch. This rubber block has good flexibility and sealing properties, and a cable pass-through hole is provided in its center. This hole is mainly used for various cables to pass through, providing an orderly cable routing channel. The sealing effect of the rubber block effectively prevents dust, moisture, and impurities from entering the enclosure through the cable pass-through hole, ensuring a clean and dry environment inside the enclosure and thus ensuring the normal operation of the equipment.

[0007] As a further description of the above technical solution:

[0008] The suspension mechanism includes a hook, one end of which is fixedly connected to the outer wall of the housing. A hanging rod is engaged with the inner wall of the hook. Vertical rods are fixedly connected to both ends of the hanging rod. A crossbeam is fixedly connected between adjacent vertical rods. An expansion bolt is provided on the outer wall of the crossbeam. A level is fixedly connected to the outer wall of the hanging rod.

[0009] Through the above technical solution: one end of the hook is firmly fixed to the outer wall of the outer shell, ensuring sufficient connection strength between the hook and the outer shell to withstand various loads of subsequent suspension. The hook has a unique inner wall that engages with the hanging rod, so that the hanging rod can be stably installed inside the hook and will not easily loosen or fall off during normal use. A vertical rod is fixedly connected to each end of the hanging rod, ensuring a firm and reliable connection between the vertical rod and the hanging rod. The two vertical rods are fixedly connected to a crossbeam on an adjacent side. Expansion bolts are provided on the outer wall of the crossbeam. The function of the expansion bolts is to firmly install the crossbeam on the required support structure. A level is also fixedly connected to the outer wall of the hanging rod. The level helps to determine whether the entire mechanism is in a horizontal state, ensuring that the suspension can be in a horizontal position.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the outer shell is rotatably connected to a cover, and the outer wall of the cover is fixedly connected to a handle.
