Description

Technical Field

[0001] This utility model relates to the field of communication network equipment technology, and in particular to a protection device for a communication fiber optic splitter. Background Technology

[0002] In modern communication network systems, fiber optic splitters are key components for optical signal distribution and access, and are widely used in various optical communication scenarios such as fiber to the home and fiber to the building. Fiber optic splitters are usually connected to multiple fiber optic patch cords through plug-in connection. Each splitter is responsible for transmitting one optical signal, and its operational stability is directly related to the reliability and service quality of the entire communication link.

[0003] In actual installation and use, the splitter ports of existing fiber optic splitters are often exposed. Some ports are connected to fiber optic patch cords, while others may not be connected at all. The overall structure lacks effective protection and fixing measures. On the one hand, the patch cords that are already connected may become loose due to external pulling, cable sagging, or micro-vibration during long-term operation, affecting the stability of the optical path. On the other hand, unused ports are exposed and are prone to accumulating dust or moisture, which can lead to optical signal attenuation or interface corrosion, reducing equipment performance. Utility Model Content

This solution sets a pair of flip-closeable protective covers in the splitter's branch port area, combined with a torsion spring reset structure, a surrounding abutment block, and a full-coverage elastic pad design. This not only achieves stable clamping and shock protection for connected jumpers, but also provides dust and moisture protection for unused ports, further improving connection stability and operational reliability. The overall structure is compact and easy to operate, effectively improving the protection effect and service life of the fiber optic splitter in complex environments, and has good practicality and promotion value.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A protective device for a communication fiber optic splitter includes a splitter and a pair of protective covers. One end of the splitter is connected to multiple branch ports, and the end of the splitter near the branch ports is connected to multiple connecting blocks. The pair of protective covers are rotatably connected to the connecting blocks, and the pair of protective covers cover the outside of the multiple branch ports. A torsion spring is connected to the connection between the protective cover and the connecting block. An abutment block is integrally formed at one end of the pair of protective covers that are close to each other, and an elastic pad is connected to the abutment block.

[0007] Preferably, the abutment blocks are arranged around the edge of the protective cover.

[0008] Preferably, the width of the side of the abutment block furthest from the beam splitter is greater than the width of the other two sides.

[0009] Preferably, the elastic pad covers the entire surface of the abutment block.

[0010] Preferably, the protective cover is made of a transparent material.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] This solution, by setting a pair of flip-close protective covers in the splitter port area, combined with a torsion spring reset structure, a surrounding contact block, and a full-coverage elastic pad, not only achieves stable clamping and shock protection for connected jumpers, but also provides dust and moisture protection for unused ports, further improving connection stability and operational reliability.

[0017] In actual installation and use, the splitter ports of existing fiber optic splitters are often exposed. Some ports are connected to fiber optic patch cords, while others may not be connected at all. The overall structure lacks effective protection and fixing measures. On the one hand, the patch cords that are already connected may become loose due to external pulling, cable sagging, or micro-vibration during long-term operation, affecting the stability of the optical path. On the other hand, unused ports are exposed and are prone to accumulating dust or moisture, which can lead to optical signal attenuation or interface corrosion, reducing equipment performance.

[0018] Therefore, this utility model provides a fiber optic splitter port protection structure that combines port sealing protection and cable fixing functions, which can simultaneously meet the comprehensive usage requirements of connection stability, dust and moisture protection, and port management, so as to improve the operational reliability and maintenance convenience of the splitter in complex environments.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0020] like Figure 1-3 The protective device for a communication fiber optic splitter shown includes a splitter 1 and a pair of protective covers 2. One end of the splitter 1 is connected to multiple branch ports, and the end of the splitter 1 near the branch ports is connected to multiple connecting blocks 4. The pair of protective covers 2 are rotatably connected to the connecting blocks 4, and the pair of protective covers 2 cover the outside of the multiple branch ports. A torsion spring is connected at the connection between the protective cover 2 and the connecting blocks 4. The pair of protective covers 2 are integrally formed with abutment blocks 5 at their close ends, and elastic pads 3 are connected to the abutment blocks 5.

[0021] In this embodiment, the optical fiber splitter protection device achieves the functions of covering the connection port and clamping and fixing the cable by setting a pair of flip-up protective covers 2 in the splitter port area of ​​the splitter 1. The protective covers 2 can be flipped up and down through the connecting block 4, and can be automatically closed by the restoring force generated by the torsion spring to prevent the port from being exposed. When connecting the jumper, the two protective covers 2 can form a light pressure to fix the cable when they are closed. At the same time, the built-in elastic pad 3 provides flexible buffer to prevent the optical cable from being crushed. This structure not only simplifies the connector management and improves the stability of the cable connection, but also effectively prevents dust and moisture from entering the splitter port area and extends the service life of the splitter 1. It is a highly integrated, highly protective, and easy-to-operate protection structure.

[0022] The abutment block 5 is arranged around the edge of the protective cover 2.

[0023] In this embodiment, the abutment block 5 is arranged in a ring around the edge of the protective cover 2, so that when the two protective covers 2 are closed, the abutment block 5 can form a complete contact closure ring, effectively increasing the sealing coverage area and enhancing the sealing protection effect on the optical fiber connection area. This structure can form an enclosed contact surface during the closing process, reducing the possibility of dust and moisture entering the interior of the protective cover 2, and further improving the adaptability of the communication splitter in humid and dusty environments. At the same time, this ring arrangement also provides a larger contact area for the subsequent arrangement of the elastic pad 3, thereby achieving more stable clamping support.

[0024] The width of the side of the abutment block 5 furthest from the beam splitter 1 is greater than the width of the other two sides.

[0025] In this embodiment, the abutment block 5 is designed with a widened structure on the side away from the splitter 1. This is intended to enhance the clamping force of the clamping area near the cable outlet and to reserve appropriate buffer space for the cable inlet and outlet. This structure allows a stable clamping surface to be formed in the outlet direction when the two protective covers 2 are closed. This helps to control the cable bending angle and prevent the optical cable from being pulled by suspension or shaking at the outlet, thereby reducing the risk of optical path instability or fiber breakage caused by loose joints. The widened area can also guide the cable to hang naturally, forming an orderly wiring path and improving the overall wiring neatness and engineering maintainability.

[0026] The elastic pad 3 covers the entire surface of the abutment block 5.

[0027] In this embodiment, the elastic pad 3 completely covers the surface of the contact block 5, which can provide uniform contact pressure to the optical cable when the protective cover 2 is closed, effectively avoiding damage to the optical fiber patch cord due to excessive tightness in some areas. The elastic pad 3 can be made of high-resilience silicone, EVA foam or other flexible buffer materials, which have good durability and buffer performance. This structure can achieve flexible clamping of the cable without affecting the closure and sealing, and provides slight rebound force to fit patch cords of different diameters. It has strong adaptability and avoids the size mismatch problem caused by rigid clamping method, while improving the safety and compatibility of the overall protection device.

[0028] The protective shield 2 is made of transparent material.

[0029] In this embodiment, the protective cover 2 is made of transparent material, which allows for a direct observation of the connection status of the internal ports of the splitter 1 when it is closed. This makes it easy for users to quickly confirm the port usage status, connector type, or identify optical cable tag information without having to frequently open the device for manual inspection. Transparent materials such as polycarbonate and transparent ABS have good optical transparency and mechanical strength, taking into account both visibility and protection functions. This makes the protective device both structurally rigid and visually friendly, effectively reducing misoperation and port confusion at the operation and maintenance site.
