[0001] This utility model relates to the field of communication terminal technology, specifically to an optical communication terminal with interface moisture protection function. Background Technology

[0002] Optical communication terminals are key devices in optical fiber communication networks. Their main function is to convert optical signals transmitted through optical fibers into electrical signals so that user equipment can recognize and process these signals. At the same time, they also support the conversion of electrical signals sent by user equipment into optical signals and back to the optical fiber network.

[0003] For example, when using the SJ-TX07 optical communication terminal box, its pull-out structure results in poor sealing performance of the pull-out parts. This makes the device susceptible to moisture ingress in humid or other special environments, leading to increased fiber optic attenuation, increased total channel attenuation, and in severe cases, even communication interruption, thus reducing the stability of the terminal box. Utility Model Content

[0004] The purpose of this utility model is to provide an optical communication terminal with a moisture-proof interface to solve the problem mentioned in the background art where the sealing performance of the pull-out part is poor, and moisture can easily enter the interior, leading to increased fiber attenuation, increased total channel attenuation, and in severe cases, even communication interruption, thereby reducing the stability of the terminal box.

[0009] Preferably, the outer wall of the limiting shaft is provided with a rotating groove, and the inner wall of the limiting bracket is provided with a limiting protrusion that matches the rotating groove. When the limiting bracket is in a vertical state, the limiting protrusion and the rotating groove abut against each other.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment of this utility model provides: an optical communication terminal with interface moisture-proof function, comprising:

[0023] The outer shell 1 has a hinge seat 11 above its open end, and a limiting shaft 12 is fixedly connected between the hinge seats 11. A limiting bracket 13 is rotatably connected to the outside of the limiting shaft 12, and a threaded rod 14 is threadedly connected to the other end of the limiting bracket 13. A compression ring 15 is fixedly connected to the outer wall of the threaded rod 14. The inner shell 2 is slidably connected to the inside of the outer shell 1 via a guide rail. A baffle 21 is fixedly connected to the front of the inner shell 2, and a sealing gasket 23 is laid in the contact area between the baffle 21 and the open end of the outer shell 1. By rotating the limiting bracket 13, it is made to be vertically distributed. At this time, the threaded rod 14 can be rotated to connect with the inner shell 2, and then the compression ring 15 can complete the compression of the baffle 21, thereby sealing the baffle 21 with the outer shell 1, effectively preventing water vapor from entering, and thus ensuring the stability of the optical fiber inside the inner shell 2.

[0024] Furthermore, the hinge seats 11 are symmetrically arranged at both ends of the opening of the outer shell 1. The hinge seats 11 have a U-shaped structure, and the limiting shaft 12 is located between the U-shaped structures. The outer wall of the limiting shaft 12 is provided with a rotating groove, and the inner wall of the limiting bracket 13 is provided with a limiting protrusion that matches the rotating groove. When the limiting bracket 13 is in a vertical state, the limiting protrusion and the rotating groove abut against each other. Through this limiting rotation, when the limiting bracket 13 rotates downward, it can only be in a vertical state, thereby ensuring that the threaded rod 14 can be accurately connected with the inner shell 2. Conversely, the upward rotation angle of the limiting bracket 13 does not affect the pulling of the inner shell 2.

[0025] Furthermore, the inner shell 2 has a threaded hole adapted to the threaded rod 14, and when the limiting bracket 13 is in a vertical state, the threaded rod 14 and the threaded hole are coaxially distributed. The compression ring 15 is used for compression abutment against the outer wall of the baffle 21. The end of the threaded rod 14 is provided with an anti-slip handwheel. The anti-slip handwheel can improve the friction with the hand, thereby improving the stability of the rotation of the threaded rod 14. Thus, when the limiting bracket 13 is in a vertical state, the rotation of the threaded rod 14 makes the threaded rod 14 and the threaded hole of the inner shell 2 connect with each other. At this time, their connection is mutually limited, so that the threaded rod 14 can only be axially displaced. Thus, through its displacement, the compression ring 15 is pressed against the baffle 21, thereby ensuring the sealing compression between the baffle 21 and the outer shell 1.

[0026] Furthermore, the corners of the inner shell 2 and the baffle 21 are fixedly connected by rivets, and the height of the inner shell 2 is less than the height of the baffle 21. The front of the baffle 21 is integrally formed with a support plate 22, and the support plate 22 has an L-shaped structure. The support plate 22 is used for auxiliary support and guidance of the plug-in cable. The setting of the support plate 22 can provide auxiliary support and guidance for the cable of the external plug-in terminal of the optical fiber terminal 3, further improving the stability and safety of its wiring.

[0027] Furthermore, the inner housing 2 has symmetrically distributed fiber optic terminals 3 at one end of the baffle 21, and the fiber optic terminals 3 are fixedly connected to the inner housing 2 by screws. The center of the baffle 21 has a limiting groove adapted to the height of the fiber optic terminals 3.

[0028] Working principle: The outer shell 1 and fiber optic terminal 3 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. When using this utility model, the inner shell 2 is first pulled out, and then the fiber optic terminal 3 is laid and installed. Finally, the inner shell 2 is pushed back, and then the limiting bracket 13 is rotated so that the limiting bracket 13 is in a vertical state. At this time, the rotating threaded rod 14 can be connected with the threaded hole of the inner shell 2. Continuous rotation causes the compression ring 15 to abut against the outer wall of the baffle 21, thereby pushing the baffle 21 and the outer shell 1 to squeeze each other, thus achieving a sealed closure and effectively preventing water vapor from entering.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
