DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0039] The following describes an embodiment of the present invention based on its overall structure.

[0040] An optical fiber connector, such as Figure 1-15 As shown, it includes a connecting block 110, and a connector body 100 is installed on one side of the connecting block 110. The present invention is intended to solve the problem that the optical fiber may be damaged due to loosening or bending of the optical fiber connection caused by external force at the junction between the optical fiber and the connector, and the problem that the connector is exposed to the outside when not in use, causing dust and particles to contaminate its end face, resulting in a decrease in signal transmission quality or unstable connection when it is used next time.

[0041] To this end, in this embodiment, a fixing assembly 200 is provided on the connecting block 110, and a protective assembly 300 is provided inside the connecting block 110, and opening and closing assemblies 400 are provided on both sides of the fixing assembly 200;

[0042] The fixing assembly 200 includes a left housing 210 disposed on the outside of the connecting block 110. A right housing 220, also disposed on the outside of the connector body 100, is attached to one side of the left housing 210. A circular shaft 230 is rotatably connected to both sides of the interior of the connecting block 110. First cords 240 are wrapped around the upper and lower ends of the circular shaft 230. A first inclined block 250 is fixed to the end of each set of first cords 240 away from the circular shaft 230. A second inclined block 260 is slidably connected to the first inclined block 250, and a clamping rod 280 is fixed to the side of the second inclined block 260 away from the first inclined block 250. A return spring 270 is provided around the clamping rod 280 and fixed to the second inclined block 260.

[0043] The protective component 300 includes an arc-shaped cylinder 310 arranged above the circular shaft 230 and fixed inside the connecting block 110, an arc-shaped rod 320 is sliding inside the arc-shaped cylinder 310, and a coil spring 330 is sleeved on the surface of the arc-shaped rod 320, and an air pipe 340 is connected to one side of the arc-shaped cylinder 310, and the end of the air pipe 340 away from the arc-shaped cylinder 310 is connected to a protective airbag 350, and a movable annular sleeve 360 ​​is sleeved on the surface of the protective airbag 350, and a fixed sleeve 361 is sliding on the surface of the movable annular sleeve 360, and a horizontal block 290 is fixedly connected to one side of the inner wall of the left shell 210 and the right shell 220, and two sets of card shafts 2910 are fixedly connected to the side of the horizontal block 290 close to the circular shaft 230 and are slidably connected to the connecting block 110, and a half groove 291 is provided inside the circular shaft 230 to match the horizontal block 290, and one side of the inner wall of the half groove 291 is opened. A circular groove 2911 is provided to match the two groups of card shafts 2910. The upper and lower ends of the inner walls of the left shell 210 and the right shell 220 are fixedly connected to the limit shaft 390. The upper and lower ends of the connecting block 110 and the connector body 100 are provided with straight grooves 370 for the sliding of the limit shaft 390. One side of the straight groove 370 is provided with an arc groove 380 opened at the upper and lower ends of the connecting block 110. The two groups of limit shafts 390 at the upper ends of the inner walls of the left shell 210 and the right shell 220 are rotatably connected with a threaded screw 3910. The top of the threaded screw 3910 passes through the left shell 210 and the right shell 220 and is fixed with a knob 3920. The bottom end of the arc groove 380 is provided with a limit groove 3911 that matches the threaded screw 3910. The upper and lower ends of the inner wall of the adapter 130 are provided with a fixing groove 281 that matches the card rod 280.

[0044] When the opening and closing plate 420 is opened, continue to pull the moving inclined block 440 to drive the left shell 210 and the right shell 220 to move synchronously. The left shell 210 and the right shell 220 drive the cross block 290 and the limit shaft 390 to move, so that the limit shaft 390 moves in the straight groove 370. When the cross block 290 slides to the inside of the half groove 291, the card shaft 2910 on one side of the cross block 290 will be synchronously inserted into the inside of the circular groove 2911. At the same time, the surface of the limit shaft 390 will fit into the side of the arc rod 320. At this time, the connector body 100 and the adapter 130 are plugged in. After the plugging is completed, the left shell 210 and the right shell 220 are rotated again to make the left shell 210 and the right shell 220 rotate with the circular shaft 230 as the center, thereby driving the circular shaft 230 rotates synchronously, causing the circular shaft 230 to reel in the first cord 240, and the first cord 240 pulls the first inclined block 250 to move, causing the first inclined block 250 to push the second inclined block 260 to move synchronously, and the second inclined block 260 compresses the coil spring 330 and drives the clamping rod 280 to extend from the inside of the connecting block 110, so that the clamping rod 280 is embedded in the fixing groove 281 inside the adapter 130, thereby enhancing the fixing effect between the connector body 100 and the adapter 130, ensuring that there will be no accidental falling off during use, thereby improving the stability and reliability of the connection, and at the same time ensuring that the signal transmission between the optical fibers 120 is not interfered with, thereby improving the performance and stability of the entire communication system;

[0045] When the left shell 210 and the right shell 220 rotate, they will also drive the limiting shaft 390 to move synchronously along the arc groove 380, so that the limiting shaft 390 squeezes the arc rod 320, and the arc rod 320 stretches the coil spring 330 and compresses the gas inside the arc cylinder 310, so that the gas enters the protective airbag 350 through the air pipe 340, so that the protective airbag 350 expands. When the protective airbag 350 expands to a certain coefficient, it will extend to the side close to the optical fiber 120, thereby driving the movable annular sleeve 360 ​​to move synchronously, so that the protective airbag 350 tightly wraps the connection between the connecting block 110 and the optical fiber 120, forming a stable protective layer, avoiding loosening or bending of the optical fiber 120 connection due to external force, ensuring that the signal transmission between the optical fibers 120 is not interfered with, thereby improving the overall optical fiber 120 connection system, while also helping to extend the service life of the optical fiber 120 and the connecting block 110, and reducing the cost of maintenance and replacement. Finally, by turning the knob 3920, the threaded screw 3910 is driven down, and the threaded screw 3910 is inserted into the limiting groove 3911, and the fixing component 200 and the protective component 300 are stably limited. When not in use, the left shell 210 and the right shell 220 are re-covered on the outside of the connector body 100, and the opening and closing plates 420 on both sides are reset, which can effectively prevent dust and other tiny particles from entering the interior of the connector body 100. Dust and particles may contaminate its end face, resulting in a decrease in signal transmission quality or unstable connection, thereby ensuring that the connector body 100 remains clean when used next time.

[0046] Please refer to Figures 1 to 3 An optical fiber 120 is provided on the other side of the connecting block 110, and an adapter 130 is plugged into the side of the connector body 100 away from the connecting block 110. The adapter 130 is provided with a ferrule that matches the Pin pin and is plugged into it.

[0047] By plugging the connector body 100 and the adapter 130 into each other, better transmission of the signal source is facilitated.

[0048] Please refer to Figures 7 to 15 The surfaces of the two groups of first ropes 240 are provided with guide shafts 241 for changing their extension directions. Torsion springs 231 are installed at the upper and lower ends of the circular shaft 230. The first inclined block 250 and the second inclined block 260 both slide one end of the arc rod 320 inside the connecting block 110 and extend into the arc groove 380. The protective airbag 350 is provided at the intersection between the connecting block 110 and the optical fiber 120, and the fixing sleeve 361 is fixed to the connecting block 110.

[0049] By providing the guide shaft 241 , the direction in which the first rope 240 pulls the first inclined block 250 can be changed, and the protective airbag 350 can better protect the intersection between the connecting block 110 and the optical fiber 120 .

[0050] Please refer to Figures 3 to 6 The opening and closing assembly 400 includes a round rod 410 rotatably connected to one side of the left shell 210 and the right shell 220, an opening and closing plate 420 is fixedly connected to the surface of the round rod 410, and a torsion spring is provided at the connection between the round rod 410 and the left shell 210 and the right shell 220. A second wire rope 430 is wound around the middle of the surface of the round rod 410, and the end of the second wire rope 430 away from the round rod 410 is fixedly connected to a moving inclined block 440, a base rod 450 is fixed inside the moving inclined block 440, and a rocker 460 is rotatably connected to the surface of the base rod 450, and a rocker 460 is fixed on the side close to the left shell 210. The arc-shaped clamping shaft 470 and the movable bevel block 440 are provided with a groove 481 inside, and a circular plate 480 fixed to the arc-shaped clamping shaft 470 is provided inside the groove 481. A limit spring 490 is provided on one side of the circular plate 480 and is sleeved on the arc-shaped clamping shaft 470. The arc-shaped clamping shaft 470 passes through one side of the movable bevel block 440, and a slider 4910 is fixedly connected to one side of the movable bevel block 440. A sliding groove 4911 that matches the slider 4910 is provided on one side of the left shell 210 and the right shell 220, and a clamping shaft groove 471 that matches the arc-shaped clamping shaft 470 is provided on the left shell 210 and the right shell 220.

[0051] By sliding the movable bevel blocks 440 on both sides, the movable bevel blocks 440 can better move on the outer walls of the left shell 210 and the right shell 220 through the cooperation between the slider 4910 and the slide groove 4911, so that the movable bevel blocks 440 pull the second rope 430 to move synchronously, and then drive the round rod 410 and the opening and closing plate 420 to rotate and open through the second rope 430. When the movable bevel block 440 moves to a certain position, the arc-shaped clamping shaft 470 is inserted into the clamping shaft groove 471 under the action of the limit spring 490 to complete the fixation of the movable bevel block 440, preventing the movable bevel block 440 from sliding under the action of the torsion spring.

[0052] When in use, by sliding the moving inclined blocks 440 on both sides, the moving inclined blocks 440 can better move on the outer walls of the left shell 210 and the right shell 220 through the cooperation of the sliders 4910 and the slide grooves 4911, so that the moving inclined blocks 440 pull the second rope 430 to move synchronously, and then drive the round rod 410 and the opening and closing plate 420 to rotate and open through the second rope 430. When the moving inclined blocks 440 move to a certain position, the arc-shaped clamping shaft 470 is inserted into the clamping shaft groove 471 under the action of the limit spring 490, thereby completing the fixing of the moving inclined blocks 440, preventing the moving inclined blocks 440 from sliding under the action of the torsion spring;

[0053] When the opening and closing plate 420 is opened, continue to pull the moving inclined block 440 to drive the left shell 210 and the right shell 220 to move synchronously. The left shell 210 and the right shell 220 drive the cross block 290 and the limit shaft 390 to move, so that the limit shaft 390 moves in the straight groove 370. When the cross block 290 slides to the inside of the half groove 291, the card shaft 2910 on one side of the cross block 290 will be synchronously inserted into the inside of the circular groove 2911. At the same time, the surface of the limit shaft 390 will fit into the side of the arc rod 320. At this time, the connector body 100 and the adapter 130 are plugged in. After the plugging is completed, the left shell 210 and the right shell 220 are rotated again to make the left shell 210 and the right shell 220 rotate with the circular shaft 230 as the center, thereby driving the circular shaft 230 rotates synchronously, causing the circular shaft 230 to reel in the first cord 240, and the first cord 240 pulls the first inclined block 250 to move, causing the first inclined block 250 to push the second inclined block 260 to move synchronously, and the second inclined block 260 compresses the coil spring 330 and drives the clamping rod 280 to extend from the inside of the connecting block 110, so that the clamping rod 280 is embedded in the fixing groove 281 inside the adapter 130, thereby enhancing the fixing effect between the connector body 100 and the adapter 130, ensuring that there will be no accidental falling off during use, thereby improving the stability and reliability of the connection, and at the same time ensuring that the signal transmission between the optical fibers 120 is not interfered with, thereby improving the performance and stability of the entire communication system;

[0054] When the left shell 210 and the right shell 220 rotate, they will also drive the limiting shaft 390 to move synchronously along the arc groove 380, so that the limiting shaft 390 squeezes the arc rod 320, and the arc rod 320 stretches the coil spring 330 and compresses the gas inside the arc cylinder 310, so that the gas enters the protective airbag 350 through the air pipe 340, causing the protective airbag 350 to expand. When the protective airbag 350 expands to a certain coefficient, it will extend to the side close to the optical fiber 120, thereby driving the movable annular sleeve 360 ​​to move synchronously, so that the protective airbag 350 tightly wraps the connection between the connecting block 110 and the optical fiber 120, forming a stable protective layer, avoiding loosening or bending of the optical fiber 120 connection caused by external force, ensuring that the signal transmission between the optical fibers 120 is not interfered with, thereby improving the stability and performance of the entire optical fiber 120 connection system. At the same time, it also helps to extend the service life of the optical fiber 120 and the connecting block 110, and reduce the cost of maintenance and replacement. Finally, by turning the knob 3920, the threaded screw 3910 is driven down, and the threaded screw 3910 is inserted into the limit groove 3911, so as to stably limit the fixing component 200 and the protective component 300. When not in use, the left shell 210 and the right shell 220 are re-covered on the outside of the connector body 100, and the opening and closing plates 420 on both sides are reset, which can effectively prevent dust and other tiny particles from entering the interior of the connector body 100. Dust and particles may contaminate its end face, resulting in a decrease in signal transmission quality or unstable connection, thereby ensuring that the connector body 100 remains clean when used next time. The parts not involved in this device are the same as the existing technology or can be implemented using existing technology.
