Specifically, the connecting assembly 11 serves as a connecting link between the protective cover 1 and the fiber adapter tray 2, and in a non-installed scene, for example, storage, handling or transportation after the device is processed, etc., the connecting assembly 11 ensures that the protective cover 1 can be reliably fixed on the surface of the fiber adapter tray 2, wherein the surface refers to the side of the fiber adapter tray 2 where the fiber joint 21 is located, so that the entire protection system remains stable, and the protective cover 1 is prevented from being separated from the fiber adapter tray 2 due to factors such as vibration and collision during storage, handling or transportation, so that the protection of the fiber joint 21 is lost. The protective assembly 12 constructs a safe protective space 1a to accommodate the fiber joint 21, on the one hand, the protective assembly 12 provides a physical barrier for the fiber joint 21 to block external extrusion and mechanical impact and other adverse factors, and protects the optical performance and mechanical structure of the fiber joint 21 from being damaged; on the other hand, the mounting groove 12a on the protective assembly 12 provides accurate positioning and a connecting interface for the fiber adapter tray 2 during installation, so that the fiber adapter tray 2 can be accurately positioned during installation, and a stable overall structure is formed with the protective cover 1.

[0029] By such arrangement, the effective protection and convenient operation of the fiber joint 21 of the fiber adapter 2 in the two key stages before installation and during installation are realized. In the non-installation scenario, the reliable protection mechanism can greatly reduce the probability of damage to the fiber joint 21 due to external factors, and reduce the maintenance cost and time cost caused by the damage of the fiber joint 21. In the installation stage, the design of the installation slot 12a makes the installation of the fiber adapter 2 more convenient and accurate, improves the installation efficiency, and also ensures the stability after installation, which is conducive to the normal operation of the entire optical fiber system. The universal protective cover 1 not only realizes the protection of the fiber joint 21 during storage, transportation or the like, but also serves as a temporary support base during installation to realize the installation of the fiber adapter 2, without the need to purchase separate protective devices and installation devices for storage, transportation or the like, thereby saving space and cost; the universal protective cover 1 makes the storage, transportation or the like and the installation process of the fiber adapter 2 more convenient, and the installation operation of the fiber adapter 2 can be realized at the same time as the protective cover 1 is removed, thereby improving the work efficiency; the protective cover 1 with the two functions can be designed and produced according to a unified standard.

[0030] It should be noted that the specific structure of the connecting assembly 11 is not limited here, and the protective cover 1 can be fixed to the side of the fiber adapter 2 and support the protective assembly 12. As shown in Figure 2 In the preferred case, the connecting assembly 11 includes a first connecting plate 111 and a second connecting plate 112, the first connecting plate 111 is connected to one side of the protective assembly 12, and the second connecting plate 112 is connected to the other side of the protective assembly 12. The one side and the other side of the protective assembly 12 described here represent different side edges of the protective assembly 12. By designing the connecting plates on both sides, a stable support structure is provided for the protective assembly 12, and the reliability of the connection between the protective cover 1 and the fiber adapter 2 is enhanced. This double-sided connection method can evenly distribute the connecting force and avoid the stress concentration problem that may be caused by single-sided connection, thereby improving the stability and durability of the entire protective cover 1 during storage, transportation or the like and installation. The first connecting plate 111 and the second connecting plate 112 can be located adjacent to each other or opposite to each other on the protective assembly 12. For example, in the case where the protective assembly 12 forms a quadrilateral in the top view, the first connecting plate 111 and the second connecting plate 112 can be located at adjacent two edges of the quadrilateral, or can be located at opposite two edges of the quadrilateral.

[0031] The specific connection method between the connecting assembly 11 and the fiber adapter 2 during storage, transportation or the like is not limited here, and can be screwing, clamping or bonding, etc. In combination Figure 1 and Figure 2In a preferred embodiment, the first connecting plate 111 and the second connecting plate 112 have multiple first mounting holes 11a, and the fiber optic adapter plate 2 has multiple second mounting holes 2a. The multiple first mounting holes 11a and the multiple second mounting holes 2a are arranged in a one-to-one correspondence. The connecting assembly 11 and the fiber optic adapter plate 2 are connected by bolts provided in the first mounting holes 11a and the second mounting holes 2a. During storage, handling, or transportation, the protective cover 1 is connected to the fiber optic adapter plate 2 through the first mounting holes 11a and the second mounting holes 2a to form a stable integral structure. The bolt connection can prevent the protective cover 1 from separating from the fiber optic adapter plate 2 during storage, handling, transportation, and use. The bolt connection also has good detachability, making it easy to remove the protective cover 1 when the fiber optic adapter plate 2 needs to be installed, thus improving the convenience of operation.

[0032] In a preferred embodiment, the plurality of first mounting holes 11a on the first connecting plate 111 are located on opposite sides of the first connecting plate 111, and the plurality of first mounting holes 11a on the second connecting plate 112 are located on opposite sides of the second connecting plate 112. The specific number of first mounting holes 11a is not limited here; in optional embodiments, such as... Figure 2 As shown, taking the second connecting plate 112 as an example, two first mounting holes 11a are provided on the second connecting plate 112 near the connecting component 11, and two more first mounting holes 11a are provided on the opposite side of the second connecting plate 112. The arrangement of the first mounting holes 11a on the first connecting plate 111 is the same as that on the second connecting plate 112, and will not be described again here. This arrangement of the first mounting holes 11a significantly enhances the stability of the connection between the protective cover 1 and the fiber optic adapter plate 2. During storage, handling, or transportation, it can more effectively resist various complex external forces, reducing the risk of displacement or detachment of the protective cover 1 due to loose connection, thereby better protecting the fiber optic connector 21. At the same time, this multi-connection point design also improves the reliability and durability of the connection structure.

[0033] It should be noted that the specific structure of the protective component 12 is not limited here. It can form a protective space 1a on the side of the fiber optic adapter 2, effectively protecting the fiber optic connector 21 through the protective space 1a. For example, side plates can be provided around the fiber optic connector 21, with a top plate on top of the side plates to achieve all-around protection of the fiber optic connector 21. Alternatively, side plates can be provided on two opposite sides of the fiber optic connector 21, with a top plate on top of the two side plates to achieve protection of the fiber optic connector 21. Figure 1 and Figure 2In a preferred embodiment, the protective assembly 12 includes a first protective side plate 121, a protective top plate 122, and a second protective side plate 123. The first side plate 121 is fixedly connected to a first connecting plate 111, and the second side plate 121 is fixedly connected to the first side plate 122. The first side plate 123 is fixedly connected to the second connecting plate 112, and the second side plate 123 is fixedly connected to the second side plate 122. The protective assembly 12 forms a protective space 1a through the first protective side plate 121, the protective top plate 122, and the second protective side plate 123. Specifically, the first protective side plate 121 and the second protective side plate 123 support the protective top plate 122. The first protective side plate 121 is connected to the first connecting plate 111, and the second protective side plate 123 is connected to the second connecting plate 112, thereby constituting the overall structure of the protective cover 1.

[0034] In a preferred embodiment, the first connecting plate 111, the first protective side plate 121, the protective top plate 122, the second protective side plate 123, and the second connecting plate 112 are connected sequentially in a U-shape arrangement. Specifically, the first connecting plate 111 and the second connecting plate 112 are located at both ends of the overall frame of the protective cover 1, serving to connect the fiber optic adapter plate 2 and support the entire protective cover 1. The first protective side plate 121 and the second protective side plate 123 protect the two sides of the protective space 1a, while the protective top plate 122 forms the top of the protective space 1a. This arrangement creates a symmetrical and stable protective space 1a, facilitating the connection between the protective cover 1 and the fiber optic adapter plate 2 during storage, handling, or transportation. During the installation of the fiber optic adapter plate 2, the symmetrical design of the protective cover 1 eliminates the need to consider the orientation of the protective cover 1, making installation convenient and efficient. Simultaneously, the symmetrical design of the protective space 1a provides a robust support structure capable of withstanding external pressure and impact. It should be noted that the specific method by which the first connecting plate 111, the first protective side plate 121, the protective top plate 122, the second protective side plate 123, and the second connecting plate 112 are sequentially connected is not limited here; they can be welded, snap-fitted, bonded, or integrally molded. In a preferred embodiment, the first connecting plate 111, the first protective side plate 121, the protective top plate 122, the second protective side plate 123, and the second connecting plate 112 are integrally molded to form a U-shaped integral protective cover 1. Furthermore, the protective cover 1 is made of high-strength materials, such as metal materials, like high-strength stainless steel; or polymer materials, like high-strength plastics; or composite materials, like carbon fiber composites. Using an integrally molded protective cover 1 improves the overall structural integrity; it also saves production and processing steps, reducing costs; and it facilitates the installation and disassembly of the protective cover 1, improving installation and disassembly efficiency.

[0035] Combination Figure 2 and Figure 4In the preferred case, the installation slot 12a comprises a first portion 121a, a second portion 122a and a third portion 123a.

At the same time, the contact between the first portion 121a and the third portion 123a and the fiber adapter panel 2 can also provide a certain friction force to prevent the fiber adapter panel 2 from moving after installation. The second portion 122a is formed through the protective top plate 122 and is in contact with the two sides of the fiber adapter panel 2 during installation, which further assists in positioning the fiber adapter panel 2 and ensures the accuracy of the position of the fiber adapter panel 2 in the vertical direction. In addition, the contact between the second portion 122a and the side of the fiber adapter panel 2 can also provide a certain support force to enhance the stability after installation.

During the insertion process, the two sides of the first portion 121a are in abutment with the two sides of the fiber adapter panel 2, and the end is in abutment with the circumferential side of the fiber adapter panel 2, achieving preliminary positioning. As the fiber adapter panel 2 continues to be inserted, the top thereof comes into contact with the second portion 122a of the installation slot 12a, the two sides of the second portion 122a are in abutment with the two sides of the fiber adapter panel 2, further determining the position of the fiber adapter panel 2 in the vertical direction. Finally, the side of the fiber adapter panel 2 reaches the third portion 123a of the installation slot 12a, the two sides of the third portion 123a are in abutment with the two sides of the fiber adapter panel 2, and the end is in abutment with the circumferential side of the fiber adapter panel 2, completing the entire installation process. Through the cooperative action of the three portions, precise positioning and stable installation of the fiber adapter panel 2 are achieved.

[0037] It should be noted that the second portion 122a formed through the protective top plate 122 is as shown in Figure 2As shown, the second part 122a divides the protective top plate 122 into two parts, facilitating the installation of the fiber adapter tray 2.
