Description

Technical Field

[0001] This utility model relates to the field of optical fiber connection structures, and in particular to a DVS distributed optical fiber connection structure. Background Technology

[0002] DVS (Distributed Fiber Optic Connection) is a structure used to connect optical fibers, typically employing simple point-to-point fusion splicing or mechanical connection methods.

[0003] The utility model disclosed in CN214151137U is an optical fiber connector and optical fiber connection structure. The key technical points are as follows: by designing the locking clip installed on the outside of the connector housing as a forward protruding arm that can lock and fasten with the adapter-side locking structure by means of elastic deformation recovery, and can also achieve frictionless unlocking of the latch and the adapter-side locking structure by means of the seesaw principle, it can ensure that the latch on the connector end and the locking structure on the adapter end are locked. On the other hand, during the unlocking process, the latch and the locking structure gradually separate away from each other, resulting in a gradual reduction of friction. Therefore, it can avoid mechanical wear on the locking components during the unlocking process, extend the service life of the connector, and ensure the coupling accuracy between the connector and the adapter and the optical fiber communication transmission effect during subsequent connection and use.

[0004] Regarding the above-mentioned issues, the following technical defects have been found: In the use of existing fiber optic connectors, due to the lack of external protective structure, the fiber optic connectors are easily damaged by being stepped on or bumped, which will reduce the service life of the fiber optic connectors.

[0005] Therefore, it is necessary to provide a new DVS distributed optical fiber connection structure to solve the above-mentioned technical problems. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figure 1 and Figure 2 The present invention provides a DVS distributed optical fiber connection structure, comprising: two DVS devices 1, an optical fiber connector 4, and two optical fiber bodies 2. The optical fiber bodies 2 are installed on one side of the DVS devices 1, and the optical fiber connector 4 is installed at the ends of the two optical fiber bodies 2 that are close to each other. The external of the optical fiber connector 4 is provided with a protective component 3.

[0031] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The protective component 3 includes a protective box 301, which is fitted over the fiber optic connector 4. Two sealing plates 302 are affixed to the upper surface of the protective box 301. A sliding plate 303 is fixedly connected to one side of each sealing plate 302. Two support plates 304 are fixedly connected to one side of the outer wall of the protective box 301. A support rod 305 is fixedly connected to the side of the two support plates 304 that are close to each other. An ear plate 307 is slidably connected to the arc surface of the support rod 305. An adjusting ring 306 is threaded onto the arc-shaped surface of the support rod 305. The lower surface of the adjusting ring 306 abuts against the upper surface of the ear plate 307. An adjusting plate 308 is fixedly connected to one side of the ear plate 307. The cross-section of the adjusting plate 308 is an isosceles trapezoid. Sliding holes 309 are provided on both sides of the inclined side of the adjusting plate 308. The inner wall of the sliding hole 309 is slidably connected to the sliding plate 303. Cable guide holes 310 are provided on both sides of the protective box 301. The optical fiber body 2 slides through the inner wall of the cable guide hole 310. By setting the protective component 3, the optical fiber connector 4 can be placed in the sealed space formed by the protective box 301 and the sealing plate 302 during use, thereby preventing the optical fiber connector 4 from being damaged by being stepped on or bumped, and improving the service life of the optical fiber connection structure. A spring 319 is sleeved on the arc-shaped surface of the support rod 305. The two ends of the spring 319 are fixedly connected to the lower surface of the ear plate 307 and the upper surface of one of the support plates 304, respectively. When the rotating adjusting ring 306 moves away from the ear plate 307, the spring 319 pushes the ear plate 307 to move upward automatically, and the ear plate 307 drives the adjusting plate 308 to move upward automatically. A groove 314 is provided at the bottom of the inner wall of the protective box 301. Two clamping plates 316 are slidably connected to the inner wall of the groove 314. A lead screw 315 is threaded through the side of the two clamping plates 316. The arc surface of the lead screw 315 has a bidirectional thread, and the lead screw 315 is rotatably connected to the inner wall of the groove 314. When it is necessary to clamp and limit the fiber optic connector 4 inside the protective box 301, first rotate the lead screw 315 to drive the two clamping plates 316, so that the two clamping plates 316 move towards each other simultaneously along the inner wall of the slide groove 314. When the clamping plates 316 abut against the side of the fiber optic connector 4, the clamping and positioning of the fiber optic connector 4 is completed. When it is necessary to release the clamping and positioning of the fiber optic connector 4, rotate the lead screw 315 in the opposite direction. The lead screw 315 drives the two clamping plates 316 to separate from the fiber optic connector 4, thus releasing the positioning of the fiber optic connector 4. By setting the above structure, fiber optic connectors 4 of different sizes can be fixed and securely fixed inside the protective box 301, improving the applicability of the protective component 3. A rotating rod 318 is rotatably inserted on one side of the outer wall of the protective box 301. The cross-section of the rotating rod 318 is "T" shaped, and one end of the rotating rod 318 is fixedly connected to one end of the lead screw 315. Personnel can rotate the rotating plate to drive the lead screw 315 to rotate, achieving the effect of convenient control of the lead screw 315. Rubber pads 317 are fixedly connected to the sides of the two clamping plates 316 that are close to each other, and the rubber pads 317 are adapted to the size of one side of the clamping plate 316.Rubber pad 317 increases the friction of clamp 316 near fiber optic connector 4, thereby improving the limiting effect of clamp 316 on fiber optic connector 4. Positioning rods 312 are fixedly connected to both sides of the outer wall of protective box 301, and positioning plates 311 are fixedly connected to the opposite sides of the two sealing plates 302. The positioning plates 311 are slidably connected to the arc surfaces of the positioning rods 312. When the sliding plate 303 moves the sealing plate 302, the positioning plates 311 fixed to the sealing plate 302 move along the arc surfaces of the positioning rods 312, thereby improving the stability of the sealing plate 302 during movement. Reinforcing ribs 313 are fixedly connected to the four corners of the inner wall of protective box 301. The reinforcing ribs 313 are made of aluminum alloy. By setting aluminum alloy reinforcing ribs 313 on the inner wall of protective box 301, the overall strength of protective box 301 can be effectively improved, thereby increasing the extrusion resistance of protective box 301.

[0032] The working principle of the DVS distributed optical fiber connection structure provided by this utility model is as follows: When it is necessary to use the protective component 3 to seal and protect the optical fiber connector 4, first place the optical fiber connector 4 to be protected into the protective box 301, then rotate the rotating rod 318 to drive the lead screw 315 to rotate. The lead screw 315 drives the two clamping plates 316, so that the two clamping plates 316 move towards each other along the inner wall of the slide groove 314. When the clamping plates 316 drive the rubber pad 317 to abut against the side of the optical fiber connector 4, the clamping and positioning of the optical fiber connector 4 can be completed. After the optical fiber connector 4 is fixed and stable, rotate the adjusting ring 306 to move it downward along the arc surface of the support rod 305. When the adjusting ring 306 moves downward, it will move the ear plate 307. The pressure causes the ear plate 307 to move downwards, which in turn moves the adjusting plate 308 downwards. As the adjusting plate 308 moves, it uses its two oblique sliding holes 309 to drive two sliding plates 303, causing the two sliding plates 303 to move the two sealing plates 302 towards each other simultaneously. Once the two sealing plates 302 block the upper opening of the protective box 301, the rotation of the adjusting ring 306 stops, thus sealing the protective box 301. The fiber optic connector 4 is then placed within the sealed space formed by the protective box 301 and the sealing plates 302, effectively preventing damage to the fiber optic connector 4 caused by stepping or bumping. When it is necessary to open the sealing plates 302 to remove the fiber optic connector 4 from inside the protective box 301, first... Rotating the adjusting ring 306 causes it to move upward along the arc of the support rod 305. As the adjusting ring 306 moves away from the ear plate 307, the spring 319 pushes the ear plate 307 to move upward automatically. The ear plate 307 then drives the adjusting plate 308 to move upward automatically. The adjusting plate 308, through its two oblique side sliding holes 309, drives the two sliding plates 303, causing the two sliding plates 303 to drive the two sealing plates 302 to move away from each other simultaneously. Once the sealing plates 302 open, the rotation of the adjusting ring 306 stops. Then, rotating the rotating rod 318 in the opposite direction causes the lead screw 315 to rotate in the opposite direction. The lead screw 315 drives the two clamping plates 316 to move away from each other simultaneously. When the clamping plates 316 drive the rubber pad 317... After separation from the fiber optic connector 4, the limiting effect on the fiber optic connector 4 can be released, and personnel can then remove the fiber optic connector 4 from the protective box 301. The rubber pad 317 can increase the friction of the clamping plate 316 near the fiber optic connector 4, thereby improving the limiting effect of the clamping plate 316 on the fiber optic connector 4. In addition, when the sliding plate 303 moves the sealing plate 302, the positioning plate 311 fixed on the sealing plate 302 will move along the arc surface of the positioning rod 312, thereby improving the stability of the sealing plate 302 during movement. Finally, by setting the aluminum alloy reinforcing ribs 313 on the inner wall of the protective box 301, the overall strength of the protective box 301 can be effectively improved, thereby improving the extrusion resistance of the protective box 301.
