[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] Based on the vigorous development of the network communication industry, in order to ensure high-quality, stable bandwidth, convenient and fast use needs of the user end, at the same time, in some special scenarios such as sewers, wells and other scenarios with high requirements for waterproofing, there are higher requirements for the waterproof performance of the communication box.

[0037] Based on the above reasons, the optical fiber adapter provided by the present invention has a novel interchangeable optical fiber adapter waterproof design structure, which can be applied to the design of outdoor waterproof communication boxes. In general, the optical fiber adapter is designed with an interchangeable adapter 200 body, in which a conventional short ear band spring clip SC type and double LC type adapter 200 can be embedded, which is simple and convenient to operate and can be directly snapped in. There is a matching rubber gasket on the inside of the adapter 200 body, which is assembled on the box body through a nut, and a rubber gasket and a dust cap 500 on the outside, which are assembled on the adapter 200 body using a rotating snap-on structure, playing an overall waterproof sealing role.

[0038] Please refer to Figure 1 , Figure 1 This is an exploded view of a specific implementation of the optical fiber adapter provided by the present invention.

[0039] In a specific embodiment, the interchangeable fiber optic adapter with a waterproof structure provided by the present invention includes a main body 100 and an adapter 200, wherein the main body 100 has an axially through-going adapter mounting hole, the inner end of the main body 100 is a mounting end, the main body 100 is detachably connected to a box body through the mounting end, and a sealing structure is provided between the main body 100 and the box body; the adapter 200 is inserted into the adapter mounting hole and is detachably fixedly connected to the main body 100 through a snap-on structure.

[0040] Specifically, the adapter 200 is a conventional short ear band spring clip SC type or double LC type adapter 200 to improve the stability of the optical link.

[0041] The mounting end of the main body 100 is a threaded connection end. After the main body 100 and the box are mounted, they are fixed by a nut 600 threadedly connected to the mounting end. The sealing structure is a sealing gasket 300, which is sleeved on the threaded connection end and fixed by a nut 600.

[0042] In order to improve the waterproof and dustproof performance, so as to better adapt to the scenes with high waterproof and dustproof requirements such as sewers and wells, the optical fiber adapter also includes a dust cap 500, which is detachably mounted on the outer end of the main body 100 and closes the open end of the adapter mounting hole. A sealing ring 400 is arranged between the dust cap 500 and the main body 100, and a groove is opened on the outer periphery of the main body 100, and the sealing ring 400 is embedded in the groove.

[0043] In this embodiment, the main body 100 is an interchangeable detachable structure, in which a conventional short ear band spring clip SC type or double LC type adapter 200 can be embedded, and a snap-fit ​​structure is used to snap the adapter 200 and the main body 100 together. A matching sealing gasket 300 is provided on the inner side of the adapter 200 body, which is assembled on the box body through a nut 600, and a sealing ring 400 and a dust cap 500 are provided on the outer side, which are assembled on the adapter 200 body using a snap-fit ​​structure to play an overall waterproof sealing role.

[0044] In this way, the adapter 200 and the main body 100 adopt a split structure and are connected in a detachable manner, which facilitates the assembly of the adapter 200, reduces the difficulty of processing and assembly, and improves production efficiency; at the same time, adopting this structural form, the adapter 200 can use a mature SC / dual LC short ear adapter 200, avoiding the problem that the adapter 200 is easily damaged when inserted with a ceramic sleeve, the good product efficiency is high, and the optical link is relatively stable.

[0045] Specifically, Figure 2-Figure 8 As shown, the snap-fit ​​structure includes a spring sheet and a receiving groove 8; wherein, the spring sheet is installed on the outer side wall of the adapter 200, the receiving groove 8 is opened on the hole wall of the adapter mounting hole, and the spring sheet is located in the receiving groove 8 after being popped up.

[0046] The receiving groove 8 is extended along the installation direction of the adapter 200. During the installation process, the adapter 200 is pushed inward along the adapter installation hole. After the spring sheet reaches the specified position, it pops up and embeds into the receiving groove 8, thereby achieving snap-on fixation.

[0047] In order to ensure that the spring piece remains stable after reaching the designated position, thereby improving the installation position accuracy of the adapter 200 and avoiding over-installation of the spring piece, the spring piece includes a pop-up portion 6 and a buckle portion 7; the inner end of the accommodating groove 8 has a buckle position 4, and the pop-up portion 6 is located in the accommodating groove 8 after being popped up, and the buckle portion 7 is snapped into the buckle position 4 after being popped up.

[0048] When the adapter 200 is pushed into the adapter mounting hole, the wall of the mounting hole can be used to limit the spring. At this time, when the adapter 200 moves into place, due to the setting of the accommodating groove 8, the spring loses the restraint of the mounting hole, and the spring resets and pops up and is stuck in the accommodating groove 8.

[0049] Preferably, in order to improve the smoothness of the installation of the adapter 200 and avoid jamming, the clamping structure further includes a guide slope 1, which is arranged at the adapter installation hole and is inclined along the installation direction of the adapter 200. During the installation process, the spring piece fits with the guide slope 1. In this way, during the installation of the adapter 200, the guide slope 1 replaces the hole wall to restrain the spring piece, and can also achieve guidance, thereby improving the convenience of installation.

[0050] Furthermore, the snap-fit ​​structure also includes a snap-fit ​​guide structure 3, which is arranged at the end of the guide slope 1, and the spring sheet pops up after passing through the snap-fit ​​guide structure 3 to improve the guiding ability of the adapter 200 during installation and improve installation convenience.

[0051] In the above specific implementation, if Fig. 9 and Fig.10 Please refer to Figure 2-Figure 8 When the main body 100 and the adapter 200 are installed, the SC adapter 200 or the double LC adapter 200 is inserted from the side of the threaded connection end of the main body 100, and the spring-up portion 6 of the spring sheet contacts the guide inclined surface 1 on the main body 100, and the spring-up portion 6 is deformed and compressed, and continues to be inserted forward until the clamping position 5 of the SC adapter 200 or the double LC adapter 200 contacts the stop position 2 of the main body 100. After the spring sheet of the SC adapter 200 or the double LC adapter 200 passes through the appropriate buckle guide structure 3, the spring-up portion 6 is located in the receiving groove 8 after being popped up, and the buckle portion 7 is snapped into the buckle position 4 after being popped up. If the type of the adapter 200 needs to be changed, a special tool is used to insert it into the buckle position 4, and the spring sheet is compressed and then pushed out of the adapter 200.

[0052] When the main body 100 is connected to the box, Fig.11 As shown, the sealing gasket 300 is first assembled on the threaded side of the main body 100, and then tightened and installed on the box body by a nut.

[0053] When installing the dust cap 500, Fig.12 As shown, the main body 100 is first assembled with the sealing ring 400, and the dust cap 500 is matched with the card slot of the adapter 200 through the card point, and the front end of the dust cap 500 squeezes the sealing ring 400 to play a waterproof and sealing role.

[0054] In the above specific implementation, the optical fiber adapter provided by the present invention has the following technical effects:

[0055] 1. Directly use the existing mature SC / dual LC short ear adapter 200, and use the common assembly method to assemble the waterproof adapter 200 body and the SC / dual LC short ear adapter 200, which solves the difficulty of high-precision integrated injection molding, and the processing and assembly process is relatively simple;

[0056] 2. Due to the use of the mature SC / dual LC short ear adapter 200, the problem of easy damage of the existing ceramic sleeve insertion adapter 200 is avoided, and the good product efficiency is high;

[0057] 3. Compared with the existing outdoor adapter 200 mold, the processing efficiency is also high, and the product cost is greatly reduced;

[0058] 4. Due to the use of the mature SC / dual LC short ear adapter 200, the optical link is relatively stable.
