Description

Technical Field

[0001] This utility model belongs to the field of fiber optic couplers and relates to a waterproof fiber optic coupler. Background Technology

[0002] An optical fiber coupler is a device that allows for detachable connection between optical fibers. It precisely aligns the two end faces of the optical fibers to maximize the coupling of the light energy output from the transmitting fiber to the receiving fiber and integrate it into the optical link, thereby minimizing the impact on the system. For waveguide-type optical fiber couplers, it is generally a component with a Y-shaped branch, which can divide the optical signal input from a single optical fiber into equal parts.

[0003] Application No. 202122889708.5 discloses a waterproof and corrosion-resistant fiber optic coupler. The technical purpose of this application is to dissipate heat. However, the fiber optic coupler still has a problem: when the fiber optic plug and the fiber optic socket are not connected, the fiber optic plug is scattered on the ground and is prone to tangling. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a waterproof fiber optic coupler.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a waterproof fiber optic coupler, including a fiber optic plug and a fiber optic socket, each connected to a fiber optic cable. The fiber optic plug has snap-fit ​​units connected to both sides. Each snap-fit ​​unit includes a fixed base and a slide rail fixedly connected to the fiber optic plug. A sliding seat is slidably connected to the slide rail. A rotating rod is rotatably connected to the fixed base. The rotating rod is threadedly connected to the sliding seat. Screw-hole seats are fixedly connected to both sides of the fiber optic socket. A threaded hole is provided at the end of the rotating rod away from the fixed base. A snap-fit ​​plate is provided at the upper end of both the fixed base and the sliding seat. The snap-fit ​​plate has snap-fit ​​grooves for positioning the fiber optic cable.

[0006] Preferably, the rotating rod is fixedly connected to two baffles, which are arranged on both sides of the fixed base.

[0007] Preferably, the fiber optic socket is provided with a rubber sealing ring.

[0008] Preferably, both the fixed seat and the movable seat have grooves at their top ends, and the grooves are connected to a rotating groove.

[0009] Preferably, the end of the rotating rod near the fixed base is provided with a rotating handle.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention includes a snap-fit ​​unit comprising a fixed base and a rotating rod rotatably connected to the fixed base. The rotating rod is threadedly connected to a sliding base. By rotating the rotating rod, the sliding base moves, thereby adjusting the distance between the two snap-fit ​​plates. This facilitates the snap-fitting of the two snap-fit ​​plates onto tabletops of different thicknesses. The snap-fit ​​plates are provided with snap-fit ​​grooves for positioning fiber optic cables. Furthermore, the snap-fit ​​plates are rotatable and foldable. Therefore, this invention facilitates snap-fitting onto tabletops, easy connection to another fiber optic cable, and convenient storage and organization of fiber optic plugs. Additionally, this invention is easy to use. Attached Figure Description

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a waterproof fiber optic coupler includes a fiber optic plug 1 and a fiber optic socket 2. Each of the fiber optic plug 1 and the fiber optic socket 2 is connected to a fiber optic cable 3. For easy storage and organization, the fiber optic plug 1 is connected to two snap-fit ​​units 4 on both sides. Each snap-fit ​​unit 4 includes a fixed base 41 fixedly connected to the fiber optic plug 1 and a slide rail 42. A sliding seat 43 is slidably connected to the slide rail 42. A rotating rod 44 is rotatably connected to the fixed base 41, and the rotating rod 44 is threadedly connected to the sliding seat 43, passing through the sliding seat 43. Therefore, when the rotating rod 44 is rotated, its position relative to the fixed seat 41 remains unchanged, while the sliding seat 43 moves along the rotating rod 44. The fiber optic socket 2 is fixedly connected to screw hole seats 11 on both sides. The screw hole seats 11 are provided with threaded holes 111 at the end of the rotating rod 44 away from the fixed seat 41. The rotating rod 44 can be threadedly connected to the screw hole seats 11, thereby fixing the fiber optic plug 1 to the fiber optic socket 2. The fixed seat 41 and the sliding seat 43 are both provided with snap-fit ​​plates 45 at their upper ends. The snap-fit ​​plates 45 are provided with snap-fit ​​grooves 451 for positioning the fiber optic cable 3.

[0021] Specifically, the steps for fixing the fiber optic plug 1 and the fiber optic socket 2 according to this utility model are as follows: insert the fiber optic plug 1 into the fiber optic socket 2, and insert the end of the rotating rod 44 away from the fixing base 41 into the screw hole seat 11. Then, rotate the rotating rod 44 to fix the fiber optic plug 1 and the fiber optic socket 2. This utility model achieves a convenient storage and organization method: when the fiber optic plug 1 and the fiber optic socket 2 are separated, rotate the rotating rod 44 to adjust the distance between the fixing base 41 and the sliding base 43, so that the distance between the connecting plates 45 is adjusted accordingly to adapt to tabletops 5 of different thicknesses, thereby allowing the fiber optic plug 1 to be snapped onto the tabletop 5. At the same time, the connecting plate 45 on the side of the fiber optic plug 1 away from the tabletop 5 can also be snapped onto the fiber optic cable 3 of the fiber optic socket 2.

[0022] Furthermore, the rotating rod 44 is fixedly connected to two baffles 46, which are located on both sides of the fixed base 41. The baffles 46 cannot pass through the fixed base 41, thereby restricting the movement of the rotating rod 44.

[0023] Furthermore, a rubber sealing ring 12 is provided inside the fiber optic socket 2, and the fiber optic plug 1 presses the rubber sealing ring 12 to improve the waterproofness of the connection between the two.

[0024] Furthermore, both the fixed base 41 and the movable base have grooves 411 at their top ends. The grooves 411 are connected to a rotating groove 412. The grooves 411 have openings on the top side and a vertical side of the fixed base 41 / movable base, and the rotating groove 412 is located in the lower middle part of the grooves 411. The snap-fit ​​plate 45 is fixedly connected to a rotating shaft 452, which is inserted into the rotating groove 412. Therefore, the snap-fit ​​plate 45 can rotate. In this invention, its rotation range is limited to 90° by the grooves 411. Therefore, the snap-fit ​​plate 45 can be rotated and folded when not in use. When the two snap-fit ​​plates 45 in one snap-fit ​​unit 4 are folded, they rotate in different directions, but both are screwed into the space between the fixed base 41 and the sliding base 43.

[0025] Furthermore, a rotating handle 47 is provided at the end of the rotating rod 44 near the fixed base 41.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
