Description

Technical Field

[0001] This utility model belongs to the field of communication technology, specifically relating to an API device interface security protection device. Background Technology

[0002] With the widespread adoption of fiber optic communication technology, optical network terminal equipment has become a core infrastructure for home and enterprise network access. Its stable operation directly impacts the normal operation of various services such as network communication, IPTV playback, and voice calls. However, in practical applications, the installation and protection conditions for optical network terminal equipment are often rudimentary, and existing technologies have significant shortcomings in protecting its interfaces and the main body of the equipment, leading to instability in equipment operation. Specific problems include: Currently, most optical network terminal devices rely solely on the plugs for securing their network cables, fiber optic cables, and power interfaces, lacking additional locking and reinforcement. This makes them prone to detachment due to pulling or accidental contact in home environments, or cable movement and equipment displacement in enterprise environments, leading to service interruptions. Furthermore, resetting fiber optic interfaces requires professional operation, increasing maintenance costs and user experience. In addition, optical network terminal device interfaces are mostly open designs, often installed in living rooms, hallways, and other areas, some near kitchens and bathrooms, making them susceptible to moisture, dust, and grease intrusion, resulting in contact corrosion, signal attenuation, and even short circuits and burnouts. Frequent malfunctions occur in humid and dusty environments, increasing repair and disposal costs. Utility Model Content

Detailed Implementation

[0012] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0013] like Figure 1-4 As shown, an API device interface security protection device includes an optical network terminal equipment body 2, a network cable body 14, an optical fiber cable body 15, and a power cord body 16. One end of the network cable body 14 is inserted into the network cable interface on the optical network terminal equipment body 2 to realize the transmission of network data and to connect devices such as computers and routers. The fiber optic cable body 15 is inserted into the fiber optic interface of the optical network terminal equipment body 2, allowing the operator's fiber optic signal to be connected to the equipment, thus realizing the core connection for fiber optic internet access.

[0014] One end of the power cord body 16 is inserted into the power interface of the optical network terminal equipment body 2 to provide power to the equipment and ensure the normal operation of the optical network terminal equipment body 2; Refer to Appendix 1 and Appendix 2 Figure 2 The optical network terminal equipment body 2 is also equipped with a protective mechanism, which includes a protective component. The protective component includes a lower protective shell 1 located on the outer side of the bottom of the optical network terminal equipment body 2, and an upper protective shell 19 installed on the outer side of the lower protective shell 1 located on the outer side of the top of the optical network terminal equipment body 2. Both the lower housing 1 and the second mounting groove 9 are hollow structures. The lower housing 1 has an opening at the top and one end, and the upper housing 19 has an opening at the bottom and one end. The two are fastened together through the opening ends to form a cavity, and the main body 2 of the optical network terminal equipment is wrapped in the cavity. The lower protective shell 1 and the main body 2 of the optical network terminal equipment are both interference-fitted, and the upper protective shell 19 and the main body 2 of the optical network terminal equipment are also interference-fitted. After they are fastened together, the lower protective shell 1 and the upper protective shell 19 fit tightly against the outer wall of the main body 2 of the optical network terminal equipment, which can isolate external water and dust from direct contact with the main body 2 of the optical network terminal equipment. At the same time, the lower protective shell 1 and the upper protective shell 19 can resist the impact of external objects on the main body 2 of the optical network terminal equipment. In addition, observation windows are provided at the other ends of the lower housing 1 and the upper housing 19 away from the opening. When the main body 2 of the optical network terminal equipment is located in the cavity, the status of the indicator lights on the main body 2 of the optical network terminal equipment can be directly observed through the observation windows, and the operating status of the equipment can be determined without disassembly. See attached document Figure 2 and attached Figure 3 The protective mechanism also includes a positioning component, which includes a first protective plate 3 fixed to the inner side of one end of the lower protective shell 1. A second protective plate 4 is installed on the top of the first protective plate 3 and on the inner side of one end of the lower protective shell 1 via a component connection. The first protective plate 3 and the second protective plate 4 are arranged symmetrically above and below each other. The first protective plate 3 and the second protective plate 4 are respectively provided with a first mounting groove 8 for the network cable body 14, a second mounting groove 9 for the fiber optic cable body 15, and a third mounting groove 10 for the power cord body 16. After the network cable body 14, fiber optic cable body 15, and power cable body 16 are inserted into the corresponding interfaces of the optical network terminal equipment body 2, the exposed connecting wires must pass through the first mounting slot 8, the second mounting slot 9, and the third mounting slot 10 of the first protective plate 3 and the second protective plate 4. At this time, the slots of the first mounting slot 8, the second mounting slot 9, and the third mounting slot 10 physically limit the wires, restricting their horizontal and vertical displacement. After the first protective plate 3 and the second protective plate 4 are attached, the wires are clamped in the first protective plate 3 and the second protective plate 4, preventing the network cable body 14, the fiber optic cable body 15, and the power cable body 16 from falling off the interface of the optical network terminal equipment body 2 due to external pulling, thus ensuring connection stability and security. The inner side of the first mounting slot 8 is equipped with a first sealing gasket 11 for the network cable body 14, the inner side of the second mounting slot 9 is equipped with a second sealing gasket 12 for the fiber optic cable body 15, and the inner side of the third mounting slot 10 is equipped with a third sealing gasket 13 for the power cable body 16. The first protective plate 3 and the first protective plate 4 are symmetrically fitted with the first sealing gasket 11, the second sealing gasket 12, and the third sealing gasket 13. When the cable passes through, the first sealing gasket 11, the second sealing gasket 12, and the third sealing gasket 13 are tightly fitted with the outer wall of the cable due to elastic deformation, filling the gap between the cable and the first protective plate 3 and the second protective plate 4, and preventing moisture and dust from entering the interface of the optical network terminal equipment body 2 from the gap. See attached document Figure 2 -Appendix Figure 4The quick-release assembly includes two rectangular positioning blocks 5 located at both ends inside the second protective plate 4. The inner wall of the lower protective shell 1 has rectangular holes adapted to the rectangular positioning blocks 5. The interior of the second protective plate 4 has a limiting groove adapted to the rectangular positioning blocks 5. The rectangular positioning blocks 5 and the lower protective shell 1 are slidably connected through the rectangular holes. The second protective plate 4 and the rectangular positioning blocks 5 are slidably connected through the limiting grooves. One end of the two rectangular positioning blocks 5 that is close to each other is fixed and a rectangular plate 6 is fixed inside the second protective plate 4. The top of the second protective plate 4 has a positioning groove adapted to the rectangular plate 6. The positioning groove communicates with the limiting groove. The lower half of the rectangular plate 6 is located inside the positioning groove on the second protective plate 4. A spring 7 is installed between the two rectangular plates 6 and inside the positioning groove on the second protective plate 4. A sealing plate 17 is installed on the side of the first protective plate 3 and the second protective plate 4 near the inner side of the lower shell 1. After the second protective plate 4 is fixed, the sealing plate 17 is squeezed and deformed to fill the assembly gap between the first protective plate 3 and the second protective plate 4, between the first protective plate 3 and the inner wall of the lower shell 1, and between the second protective plate 4 and the inner wall of the lower shell 1, forming a secondary seal to further prevent external moisture and dust from entering the interface area of ​​the main body 2 of the optical network terminal equipment from the structural gaps. See attached document Figure 3 and attached Figure 4 Guide posts 18 are fixed at both ends of the bottom of the second protective plate 4. The first protective plate 3 is provided with guide grooves that are adapted to the guide posts 18. When the second protective plate 4 is installed, the guide posts 18 can slide along the guide grooves on the first protective plate 3 to provide pre-positioning guidance. During the docking process of the second protective plate 4 with the first protective plate 3 and the lower protective shell 1, the guide posts 18 are embedded in the guide grooves to limit the horizontal displacement of the second protective plate 4 and ensure that the rectangular positioning block 5 can be accurately aligned with the rectangular hole on the inner wall of the lower protective shell 1. This avoids the rectangular positioning block 5 from failing to be smoothly inserted due to the alignment deviation during installation, thereby improving the convenience and accuracy of the installation of the second protective plate 4. Install the second protective plate 4: Push the two rectangular plates 6 closer to each other, the rectangular plates 6 compress the spring 7 and drive the rectangular positioning block 5 to slide inward along the limiting groove of the second protective plate 4, so that the rectangular positioning block 5 retracts into the interior of the second protective plate 4; align the second protective plate 4 with the top of the first protective plate 3, the guide post 18 at one end of the rectangular positioning block 5 slides into the guide groove of the first protective plate 3 to achieve pre-positioning, after releasing the rectangular plates 6, the spring 7 elastically resets, pushes the rectangular positioning block 5 to slide outward along the limiting groove and locks into the rectangular hole in the inner wall of the lower protective shell 1, thus completing the fixation of the second protective plate 4 with the lower protective shell 1 and the first protective plate 3; To remove the second protective plate 4: push the two rectangular plates 6 closer together, the rectangular positioning block 5 compresses the spring 7 and disengages from the rectangular hole on the lower housing 1, and the second protective plate 4 can be removed, which is convenient for maintaining the interface of the main body 2 of the optical network terminal equipment or replacing the cable. In summary, this utility model provides external impact protection, interface anti-detachment protection, and waterproof and dustproof protection for the main body 2 of the optical network terminal equipment, thus constructing a protection system against impacts, detachment, and intrusion. Furthermore, this device requires no specialized tools and can be operated independently by ordinary users, avoiding the inconvenience of traditional protective devices that rely on screw fixation and require professional on-site visits. Ultimately, it ensures that the interface of the main body 2 of the optical network terminal equipment maintains stable and safe operation in complex environments, effectively extending the equipment's service life and significantly reducing maintenance costs.
