Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber modules, in particular to an optical fiber module with a compression-resistant and dust-proof structure. Background Art

[0002] Traditional optical fiber modules face various challenges in practical applications. Especially in complex environments such as industrial and outdoor areas, the modules may be accidentally impacted, resulting in the fracture of internal optical fibers or a decline in performance. In addition, the intrusion of dust and particles will also seriously affect the optical signal transmission quality of the optical fiber module and reduce the system reliability. Most of the current optical fiber modules on the market lack effective compression-resistant and dust-proof measures, which limits their application scope and service life in harsh environments.

[0003] Although there are some optical fiber modules with basic protection functions on the market, they often focus on the improvement of a single performance. For example, they only strengthen the compression resistance ability while ignoring the heat dissipation or dust-proof requirements, or only provide a simple dust-proof structure without considering the ease of use and maintenance convenience of the module. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an optical fiber module with a compression-resistant and dust-proof structure to solve the problems in the background art.

[0005] In view of this, the utility model provides an optical fiber module with a compression-resistant and dust-proof structure, including an optical fiber module main body. An installation shell with one end open is sleeved outside the optical fiber module main body. A high-strength outer shell is arranged outside the installation shell. A plurality of elastic arc-shaped plates are arranged between the installation shell and the high-strength outer shell. A heat dissipation port is opened on the outer wall of the installation shell and located between two elastic arc-shaped plates. A heat dissipation and dust filtering member is arranged on one end face of the installation shell at the position of the heat dissipation port.

[0006] The elastic arc-shaped plate includes a high-elastic rubber plate and a plurality of reinforcing elastic fibers. The high-elastic rubber plate is fixedly connected to the inner wall of the high-strength outer shell and supports on the outer wall of the installation shell. A plurality of the reinforcing elastic fibers are embedded in the inner end face of the arc surface of the high-elastic rubber plate.

[0007] Preferably: The heat dissipation and dust filtering member includes a fixing frame and a filter net. The fixing frame is fixedly connected to one end face of the installation shell. The filter net is fixedly connected to the inside of the fixing frame.

[0008] Preferably: A sealing ring is fixedly connected to the inner wall of the installation shell. When the installation shell is sleeved outside the optical fiber module main body, the sealing ring supports on the outer wall of the optical fiber module main body.

[0009] Preferably, a clamping member is movably connected to the outer wall of the high-strength housing and penetrates through the high-strength housing and the mounting housing to the inner side of the mounting housing, and the structure of the clamping member is in an "L" shape.

[0010] Preferably, one end of the clamping member is fixedly connected to a fixing plate located between the mounting housing and the high-strength housing, and both ends of the fixing plate are fixedly connected with a plurality of support springs that support inside the high-strength housing and on the outer wall of the mounting housing.

[0011] Preferably, the reinforcing elastic fiber is aramid fiber.

[0012] Preferably, the filter screen is a polyurethane foam filter screen.

[0013] From the above technical solutions, it can be seen that the embodiments of the present invention have the following advantages:

[0014] 1. For a fiber optic module with a compressive and dust-proof structure of the present invention, by adding a mounting housing and a high-strength housing around the fiber optic module body, and arranging an elastic arc plate between the two, the ability of the fiber optic module to resist external impacts is significantly improved. Furthermore, it can effectively absorb and disperse external forces, prevent damage to the internal structure of the fiber optic module, and ensure the integrity of the fiber optic module when encountering accidental collisions. The comprehensive improvement in the compressive resistance of the fiber optic module provides a strong guarantee for the stable operation of fiber optic communication equipment in various harsh environments.

[0015] 2. For a fiber optic module with a compressive and dust-proof structure of the present invention, by setting a heat dissipation and dust filtering member on the mounting housing, the present invention achieves good heat dissipation effect while maintaining excellent dust-proof performance. The filter screen in the heat dissipation and dust filtering member can block dust and particles, preventing them from entering the inside of the fiber optic module, while ensuring that the heat generated inside the module is dissipated in a timely manner, maintaining the optimal working temperature of the fiber optic module, and extending the service life. And the setting of the sealing ring further enhances the dust-proof and waterproof ability of the fiber optic module, while the combination of the clamping member, the fixing plate and the support spring greatly simplifies the installation and disassembly process of the fiber optic module, reduces the maintenance cost, and improves the efficiency and convenience of on-site operation.

However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0024] The following specifically describes an optical fiber module with a compressive and dust-proof structure according to an embodiment of the present utility model with reference to the accompanying drawings.

[0025] Embodiment

[0026] For ease of understanding, please refer to Figures 1 to 4 An embodiment of an optical fiber module with a compressive and dust-proof structure provided by the present utility model includes an optical fiber module main body 1. An installation shell 2 with an open end is sleeved outside the optical fiber module main body 1. A high-strength outer shell 3 is arranged outside the installation shell 2. A plurality of elastic arc plates 4 are arranged between the installation shell 2 and the high-strength outer shell 3. A heat dissipation opening is formed on the outer wall of the installation shell 2 and located between two elastic arc plates 4. A heat dissipation and dust filtering component 5 is arranged on one end face of the installation shell 2 at the position of the heat dissipation opening;

[0027] The elastic arc plate 4 includes a high-elastic rubber plate 41 and a plurality of reinforcing elastic fibers 42. The high-elastic rubber plate 41 is fixedly connected to the inner wall of the high-strength outer shell 3 and supports on the outer wall of the installation shell 2. A plurality of the reinforcing elastic fibers 42 are embedded in the inner end face of the arc surface of the high-elastic rubber plate 41.

[0028] It should be noted that one end of the installation shell 2 is open, which is used to sleeved outside the optical fiber module body 1 to play a basic protection role. The high-strength outer shell 3 further covers the outside of the installation shell 2 to provide additional physical protection. An elastic arc-shaped plate 4 is provided between the high-strength outer shell 3 and the installation shell 2, which is used to absorb external impact force and disperse pressure. The elastic arc-shaped plate 4 is composed of a high-elastic rubber plate 41 and a reinforcing elastic fiber 42. The high-elastic rubber plate 41 connects the inner wall of the high-strength outer shell 3 and the outer wall of the installation shell 2, so that the elastic arc-shaped plate 4 can play a better role in supporting and resisting pressure.

[0029] In an alternative embodiment: the heat dissipation and dust filtering member 5 includes a fixing frame 51 and a filter net 52. The fixing frame 51 is fixedly connected to one end face of the installation shell 2, and the filter net 52 is fixedly connected to the inner side of the fixing frame 51.

[0030] It should be noted that a heat dissipation port is provided on the installation shell 2, and a heat dissipation and dust filtering member 5 is installed at the heat dissipation port, including a fixing frame 51 and a filter net 52. The fixing frame 51 is fixed to one end face of the installation shell 2. By providing the heat dissipation and dust filtering member 5, a better heat dissipation effect can be achieved, and the dust can be filtered while dissipating heat and ventilating.

[0031] In an alternative embodiment: a sealing ring 6 is fixedly connected to the inner wall of the installation shell 2. When the installation shell 2 is sleeved outside the optical fiber module body 1, the sealing ring 6 supports on the outer wall of the optical fiber module body 1.

[0032] It should be noted that the installation shell 2 and the optical fiber module body 1 are sealed through the sealing ring 6 to prevent dust from entering.

[0033] In an alternative embodiment: a clamping member 7 that penetrates through the high-strength outer shell 3, the installation shell 2 to the inside of the installation shell 2 is movably connected to the outer wall of the high-strength outer shell 3, and the structure of the clamping member 7 is in a shape similar to "L". One end of the clamping member 7 is fixedly connected to a fixing plate 8 located between the installation shell 2 and the high-strength outer shell 3, and several support springs 9 that support inside the high-strength outer shell 3 and on the outer wall of the installation shell 2 are fixedly connected to both ends of the fixing plate 8.

[0034] It should be noted that a clamping member 7 is movably connected to the outer wall of the high-strength outer shell 3, and its shape is similar to an "L", which is convenient for the installation and disassembly of the optical fiber module body 1. One end of the clamping member 7 is connected to a fixing plate 8, and support springs 9 are provided at both ends of the fixing plate 8. Through the support springs 9, the clamping member 7 can be driven to realize the clamping and positioning of the optical fiber module body 1, and the structure of the clamping member 7 is convenient for manual operation.

[0035] In an alternative embodiment: the reinforcing elastic fiber 42 is made of aramid fiber.

[0036] It should be noted that the reinforcing elastic fiber 42 is preferably made of aramid fiber to enhance its strength and elasticity, ensuring that the fiber optic module can maintain its structural integrity when subjected to impact.

[0037] In an alternative embodiment: the filter screen 52 is a polyurethane foam filter screen.

[0038] It should be noted that the filter screen 52 is preferably a polyurethane foam filter screen, which can ensure air circulation and prevent dust from entering.

[0039] Working principle: When the fiber optic module is subjected to external impact, the high-elastic rubber plate 41 in the elastic arc plate 4 first absorbs the impact energy and disperses the impact force through its elastic properties, reducing the force directly transmitted to the fiber optic module body 1. The reinforcing elastic fiber 42 is embedded in the inner side of the high-elastic rubber plate 41, increasing the overall strength and tensile performance of the elastic arc plate 4, ensuring that the structure can remain stable even under high pressure. The filter screen 52 in the heat dissipation and dust filtering component 5 allows heat to be dissipated through the heat dissipation port, while preventing dust and impurities from entering the fiber optic module body 1, keeping the interior clean and preventing the optical components from being contaminated, which may affect the transmission efficiency. The fixing frame 51 ensures that the filter screen 52 is firmly installed at the heat dissipation port position, preventing displacement due to vibration or air flow. The sealing ring 6 between the mounting shell 2 and the fiber optic module body 1 forms a sealed environment, further preventing dust and moisture from invading the module interior and keeping the electrical and optical performance of the fiber optic module unaffected by the external environment.

[0040] As mentioned above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
