Description

Technical Field

[0001] This invention relates to the field of fiber optic amplifier technology, specifically a protective fiber optic amplifier. Background Technology

[0002] An optical fiber amplifier (OFA) is a new type of all-optical amplifier used in optical fiber communication lines to amplify signals. Based on its location and function in the optical fiber line, it is generally divided into three types: repeater amplifier, preamplifier, and power amplifier. Compared with traditional semiconductor laser amplifiers (SOAs), OFAs do not require complex processes such as photoelectric conversion, electro-optic conversion, and signal regeneration; they can directly amplify signals optically, exhibiting excellent "transparency," making them particularly suitable for repeater amplification in long-distance optical communication. It can be said that OFAs have laid a technological foundation for realizing all-optical communication.

[0003] When using existing fiber optic amplifiers, the fiber optic tip is inserted into the connection hole on the side of the fiber optic amplifier to connect the fiber optic cable to the amplifier. However, the existing connection method can lead to loosening of the connection between the fiber optic cable and the amplifier. Furthermore, the fiber optic tip protruding from the amplifier can break due to external impacts or pressure. If the amplifier is still operating at the point of fiber breakage and is not shut down or its power reduced in time, the leaked laser may cause harm to the human body. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a protective fiber optic amplifier that allows for convenient and stable installation of optical fibers and prevents fiber optic head breakage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective fiber optic amplifier, comprising a fiber optic amplifier body, circuit devices and optical devices disposed within the fiber optic amplifier body, a protective cover rotatably disposed on one side of the top side of the fiber optic amplifier body, and a connecting mechanism disposed within a connecting hole and connected to the fiber optic body. A connecting hole is provided on the side of the fiber optic amplifier body away from the protective cover and rotatably connected. A buffer groove is provided on the top side of the fiber optic amplifier body away from the protective cover and rotatably connected, and the buffer groove communicates with the interior of the connecting hole. An fiber optic head is provided at the end of the fiber optic body.

[0006] The connection mechanism includes two fixed blocks that are parallel and symmetrically inserted into the connection hole, an elastic component set in the buffer groove and controlling the two fixed blocks to move towards the protective cover rotational connection side, a connecting post inserted into the connection hole and located between the two fixed blocks and fixedly connected to the side of the connection hole, and two protective blocks that are rotatably connected on one side and have clamping grooves that match the fiber optic head on their adjacent end faces. The two protective blocks are far from the rotational connection side and far from each other's end faces, and each of the two protective blocks has a first fixing groove. The two first fixing grooves match the first inclined blocks set on the adjacent end faces of the two fixed blocks. The two fixed blocks rotate the elastic component through a torsion spring.

[0007] The fiber optic head is placed in the clamping grooves on the adjacent end faces of the two protective blocks, and the two protective blocks are rotated to clamp and fix the fiber optic head. Then, the two protective blocks are inserted into the connection hole. During the insertion of the two protective blocks into the connection hole, the elastic component is stretched, which drives the two fixing blocks to be inserted into the connection hole. In this process, the two protective blocks first resist the two fixing blocks and rotate in a direction away from each other. After the first inclined block set at the adjacent end of the two fixing blocks is inserted into the first fixing groove set in the two protective blocks, the tension of the elastic component drives the two fixing blocks to move into the buffer groove, which drives the two clamping fiber optic heads to move towards the bottom of the connection hole. This improves the stability of the fiber optic head installed in the connection hole. The clamping and fixing of the fiber optic head by the two protective blocks improves the stability of the fiber optic head installation and also protects the fiber optic head, preventing the fiber optic head from breaking due to external factors.

[0008] Preferably, the clamping groove wall is provided with a rubber pad; the two protective blocks clamp the optical fiber head and pass it through the connection hole, the connecting post passes through the connecting groove opened on the side of the two protective blocks away from the rotating connection, and the end of the optical fiber head passes through the optical fiber groove opened on the end face of the connecting post.

[0009] Preferably, the connecting mechanism further includes two clamping blocks symmetrically arranged on the top and bottom sides of the connecting column. Both clamping blocks are inclined blocks, and the distance between the adjacent inclined surfaces of the two clamping blocks and the two first inclined blocks gradually decreases from the outside of the connecting hole to the inside. Two protective blocks are inserted into the connecting hole and have two second fixing grooves on one end face, which are respectively opposite to the positions of different clamping blocks. The two protective blocks are inserted into the connecting hole and the two clamping blocks are respectively inserted into different second fixing grooves. The two protective blocks are close to each other.

[0010] Preferably, the connection mechanism further includes a disassembly assembly disposed on the fiber optic amplifier body. The disassembly assembly includes a control rod that is vertically and movably inserted through the side of the fiber optic amplifier body where the connection hole is opened, a control block disposed inside the fiber optic amplifier body and whose end face is fixedly connected to the end of the control rod, a third limiting spring that is movably sleeved on the control rod and whose two ends are respectively connected to the inner wall of the fiber optic amplifier body and the end face of the control block, and two disassembly strips that are parallel and symmetrically disposed on the end faces of the two protective blocks that are far away from each other.

[0011] Preferably, the elastic component includes a control plate that passes vertically through the buffer groove and has a first control block located on the top side of the fiber amplifier body; a second telescopic rod that passes horizontally through the buffer groove and has its two ends connected to the end face of the control plate away from the fixed block and the wall of the buffer groove, respectively; and a second limiting spring that is movably sleeved on the second telescopic rod.

[0012] The beneficial effects of this invention are as follows: The fiber optic head at the end of the optical fiber body is placed in the clamping groove opened at the adjacent end face of the two protective blocks, and the two protective blocks are rotated to clamp and fix the fiber optic head. Then, the two protective blocks are inserted into the connection hole. During the process of inserting the two protective blocks into the connection hole, the elastic component is controlled to stretch, which drives the two fixing blocks to be inserted into the connection hole. During this process, the two protective blocks first abut against the two fixing blocks and rotate in a direction away from each other. After the first inclined block set at the adjacent end of the two fixing blocks is inserted into the first fixing groove opened by the two protective blocks, the tension of the elastic component drives the two fixing blocks to move into the buffer groove, which drives the two clamping fiber optic heads to move towards the bottom of the connection hole. This improves the stability of the fiber optic head installed in the connection hole. By clamping and fixing the fiber optic head with the two protective blocks, the stability of the fiber optic head installation is improved on the one hand, and the fiber optic head is also protected on the other hand, avoiding the fiber optic head from breaking due to external factors.

[0020] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0021] Please see Figure 1-5 A protective fiber optic amplifier includes a fiber optic amplifier body 1, circuit devices and optical devices disposed within the fiber optic amplifier body 1, a protective cover 7 rotatably disposed on one side of the top side of the fiber optic amplifier body 1, and a connection mechanism disposed in a connection hole 2 and connected to the fiber optic body 19. The fiber optic amplifier body 1 has a connection hole 2 on the side away from the protective cover 7 for rotatable connection. A buffer groove 4 is provided on the top side of the fiber optic amplifier body 1 away from the protective cover 7 for rotatable connection, and the buffer groove 4 communicates with the interior of the connection hole 2. An fiber optic head is provided at the end of the fiber optic body 19.

[0022] The connection mechanism includes two fixed blocks 30 that are symmetrically inserted into the connection hole 2, an elastic component that is set in the buffer groove 4 and controls the two fixed blocks 30 to rotate and move towards the protective cover 7 on the connection side, a connecting post 25 that is inserted into the connection hole 2 and located between the two fixed blocks 30 and is fixedly connected to the side of the connection hole 2, and two protective blocks 22 that are rotatably connected on one side and have clamping grooves 23 that match the fiber optic head on their adjacent end faces. The two protective blocks 22 are far away from the rotatable connection side and far away from each other on their respective end faces, and the two first fixing grooves 27 are matched with the first inclined blocks set on the adjacent end faces of the two fixed blocks 30. The two fixed blocks 30 rotate the elastic component by a torsion spring.

[0023] like Figure 1-5 As shown, the fiber optic head on the end of the fiber optic body 19 is placed directly into the clamping groove 23 on the adjacent end face of the two rotating connecting protective blocks 22. The two protective blocks 22 are then rotated to clamp and fix the fiber optic head, and the two protective blocks 22 are controlled to pass through the connection hole 2. The elastic component is stretched to drive the two fixing blocks 30, which are set on the elastic component by a torsion spring, to pass through the connection hole 2. The first inclined block set on the fixing block 30 passes through the first fixing groove 27. The elastic component is then released, and the two protective blocks 22 are pulled into the connection hole 2 under the pulling force of the elastic component. This ensures the stability of the fiber optic head installed on the fiber amplifier body 1 and protects the fiber optic head from breakage due to external factors.

[0024] The clamping groove 23 has a rubber pad on its wall; two protective blocks 22 clamp the optical fiber head and insert it into the connection hole 2; the connecting post 25 is inserted into the connecting groove 24 on the side of the two protective blocks 22 away from the rotating connection, and the end of the optical fiber head is inserted into the optical fiber groove 26 on the end face of the connecting post 25.

[0025] like Figure 4 As shown, after the two protective blocks 22 are inserted into the connecting holes 2, the connecting post 25 is inserted into the connecting grooves 24 opened in the two protective blocks 22. At this time, the fiber optic head is inserted into the fiber optic groove 26 opened in the connecting post 25, so that the fiber optic head and the fiber optic groove 26 can be connected. The two first inclined blocks set on the two fixing blocks 30 are inserted into the first fixing grooves 27, and through the pulling force of the elastic component, the two protective blocks 22 are driven to move towards the connecting post 25, which ensures the stability of the installation between the fiber optic head and the fiber optic groove 26 opened on the connecting post 25.

[0026] The connecting mechanism also includes two clamping blocks 29 symmetrically arranged on the top and bottom sides of the connecting column 25. Both clamping blocks 29 are inclined blocks, and the distance between the two clamping blocks 29 and the adjacent inclined surfaces of the two first inclined blocks gradually decreases from the outside of the connecting hole 2 to the inside. Two protective blocks 22 are inserted into the connecting hole 2, and two second fixing grooves 28 are opened on one end face, which are respectively opposite to the positions of different clamping blocks 29. The two protective blocks 22 are inserted into the connecting hole 2, and the two clamping blocks 29 are respectively inserted into different second fixing grooves 28. The two protective blocks 22 are close to each other.

[0027] The connection mechanism also includes a disassembly assembly disposed on the fiber optic amplifier body 1. The disassembly assembly includes a control rod 16 that is vertically and movably inserted through the side of the fiber optic amplifier body 1 where the connection hole 2 is opened; a control block 18 disposed inside the fiber optic amplifier body 1 and whose end face is fixedly connected to the end of the control rod 16; a third limiting spring 17 that is movably sleeved on the control rod 16 and whose two ends are respectively connected to the inner wall of the fiber optic amplifier body 1 and the end face of the control block 18; and two disassembly strips 21 that are parallel and symmetrically disposed on the end faces of the two protective blocks 22 that are far away from each other.

[0028] like Figure 1-4 As shown, when the fiber optic head is removed from the connection hole 2, the control lever 16 is pressed and moved into the fiber optic amplifier body 1, which moves the control block 18 into the fiber optic amplifier body 1. This causes the two disassembly strips 21 to move towards the two fixing blocks 30. The two disassembly strips 21 then press against the two fixing blocks 30 from the sides, causing the two fixing blocks 30 to move away from each other. This causes the first inclined block on the fixing block 30 to leave the first fixing groove 27, making it easier to pull the two protective blocks 22 out of the connection hole 2. This allows for convenient disassembly of the fiber optic body 19. Simultaneously, the two fixing blocks 30 are moved into the buffer groove 4 by the elastic component.

[0029] The elastic component includes a control plate 20 that passes vertically through the buffer groove 4 and has a first control block 5 located on the top side of the fiber amplifier body 1; a second telescopic rod 14 that passes horizontally through the buffer groove 4 and has its two ends connected to the end face of the control plate 20 away from the fixed block 30 and the wall of the buffer groove 4, respectively; and a second limiting spring 15 that is movably sleeved on the body of the second telescopic rod 14.

[0030] like Figure 3 As shown, when the two fixed blocks 30 are located in the buffer groove 4, the second limiting spring 15 is in the normal extended state. When the two protective blocks 22 are inserted into the connecting hole 2, the first control block 5 drives the control plate 20 to move towards the connecting hole 2. At this time, the fixed blocks 30 set on the control plate 20 are inserted into the connecting hole 2, and the two fixed blocks 30 and the two protective blocks 22 abut against each other. At this time, the two fixed blocks 30 will rotate and rotate the torsion spring. After the first inclined block set on the fixed block 30 is inserted into the first fixed groove 27, the first control block 5 is released. Under the action of the second limiting spring 15, the control plate 20 will be pulled to move away from the connecting hole 2, which can pull the two protective blocks 22 into the connecting hole 2, ensuring the stability of the fiber head inserted into the fiber groove 26.

[0031] A positioning block 8 is perpendicularly arranged near one end of the protective cover 7 and away from the position where it is rotatably connected to the fiber optic amplifier body 1. When the protective cover 7 is rotatably set on the top side of the fiber optic amplifier body 1, the positioning block 8 on the protective cover 7 passes through the positioning groove 3 opened on the top side of the fiber optic amplifier body 1. A moving block 12 is movably passed through the wall of the positioning groove 3, and a locking block 13 fixedly set on the end face of the moving block 12 passes through the positioning groove 3. The moving block 12 movably passes through the control plate 20 and passes through the buffer groove 4. The end face of the moving block 12 is connected to the wall of the buffer groove 4 through the first telescopic rod 10. A first limiting spring 11 is movably sleeved on the first telescopic rod 10. The first limiting spring 11 is in a compressed state. A locking hole 9 is opened on the positioning block 8 for the locking block 13 to pass through.

[0032] When the protective cover 7 is rotated and set on the top side of the fiber optic amplifier body 1, the positioning block 8 set on the protective cover 7 passes through the positioning groove 3. During the process of the positioning block 8 passing through the positioning groove 3, the positioning block 8 first abuts against the locking block 13 and moves into the buffer groove 4, compressing the first limiting spring 11. When the positioning block 8 moves to the position where the locking hole 9 is opposite to the locking block 13, the locking block 13 will be driven to pass through the locking hole 9 under the action of the first limiting spring 11, so that the protective cover 7 is on the top side of the fiber optic amplifier body 1.

[0033] A connecting rod is horizontally arranged inside the buffer groove 4. One end of the connecting rod is fixedly connected to the side of the moving block 12, and the other end extends out of the fiber amplifier body 1. A second control block 6 is fixedly connected to the end of the connecting rod that extends out of the fiber amplifier body 1. By controlling the second control block 6 to move on the side of the fiber amplifier body 1, the moving block 12 can drive the card block 13 to move into the buffer groove 4, thereby controlling the card block 13 to leave the card hole 9, and thus controlling the protective cover 7 to rotate on the top side of the fiber amplifier body 1.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
