Description

Technical Field

[0001] The invention relates to the technical field of optical fiber amplifiers, in particular to a protective optical fiber amplifier. Background Art

[0002] Optical Fiber Amplifier (OFA) refers to a new type of all-optical amplifier used in optical fiber communication lines to achieve signal amplification. According to its position and function in the optical fiber line, it is generally divided into three types: relay amplification, pre-amplification and power amplification. Compared with the traditional semiconductor laser amplifier (SOA), OFA does not need to go through complex processes such as photoelectric conversion, electro-optical conversion and signal regeneration, and can directly perform all-optical amplification on the signal. It has good "transparency" and is particularly suitable for relay amplification in long-distance optical communications. It can be said that OFA has laid a technical foundation for the realization of all-optical communication.

[0003] When using an existing optical fiber amplifier, the optical fiber head at the end of the optical fiber is inserted into a connection hole opened on the side of the optical fiber amplifier to connect the optical fiber to the optical fiber amplifier. However, the existing connection method causes the connection between the optical fiber and the optical fiber amplifier to become loose. On the other hand, the optical fiber head extending out of the optical fiber amplifier may break due to collision or pressure from external factors. At the broken part of the optical fiber, if the optical amplifier is still working and is not shut down or the power is not reduced in time, the leaked laser may cause harm to the human body. Summary of the invention

[0020] See also Figure 1-5 A protective optical fiber amplifier comprises an optical fiber amplifier body 1, circuit devices and optical path devices arranged in the optical fiber amplifier body 1, a protective cover 7 rotatably arranged on the top side of the optical fiber amplifier body 1, and a connecting mechanism arranged in a connecting hole 2 and connected to an optical fiber body 19, a connecting hole 2 is provided on a side of the optical fiber amplifier body 1 that is away from the protective cover 7 for rotational connection, a buffer groove 4 is provided on the top side of the optical fiber amplifier body 1 that is away from the protective cover 7 for rotational connection, and the buffer groove 4 is connected to the inside of the connecting hole 2, and an optical fiber head is provided at the end of the optical fiber body 19;

[0021] The connecting mechanism includes two fixed blocks 30 which are symmetrically arranged in parallel and symmetrically in the upper and lower parts and pass through the connecting hole 2, an elastic component which is arranged in the buffer groove 4 and controls the two fixed blocks 30 to move toward the side of the protective cover 7 for rotational connection, a connecting column 25 which is arranged in the connecting hole 2 and is located between the two fixed blocks 30 and whose side is fixedly connected to the side of the connecting hole 2, and two protective blocks 22 which are rotationally connected on one side and have clamping grooves 23 matching the optical fiber head on the adjacent end faces. The two protective blocks 22 are respectively provided with first fixed grooves 27 on the end faces away from the rotational connection side and away from each other. The two first fixed grooves 27 match the first inclined blocks arranged on the adjacent end faces of the two fixed blocks 30, and the two fixed blocks 30 rotate the elastic component through a torsion spring.

[0022] like Figure 1-5 As shown, the optical fiber head on the end of the optical fiber body 19 is directly placed in the clamping groove 23 provided on the adjacent end surface of the two rotating connecting protective blocks 22, and then the two protective blocks 22 are rotated to clamp and fix the optical fiber head, and the two protective blocks 22 are controlled to pass through the connecting hole 2, and the elastic component is controlled to stretch to drive the two fixed blocks 30 set on the elastic component through the torsion spring to pass through the connecting hole 2, and the first inclined block set on the fixed block 30 is passed through the first fixed groove 27, and then the elastic component is released. Under the tension of the elastic component, the two protective blocks 22 can be pulled to move into the connecting hole 2, thereby ensuring the stability of the optical fiber head installed on the optical fiber amplifier body 1, and protecting the optical fiber head through the two protective blocks 22 to avoid the breakage of the optical fiber head due to external reasons.

[0023] The clamping groove 23 is provided with a rubber pad on the groove wall; two protective blocks 22 clamp the optical fiber head and are inserted into the connecting hole 2, the connecting column 25 is inserted into the connecting groove 24 opened 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 opened on the end face of the connecting column 25.

[0024] like Figure 4 As shown, after the two protective blocks 22 are inserted into the connecting hole 2, the connecting column 25 is inserted into the connecting groove 24 opened by the two protective blocks 22. At this time, the optical fiber head is inserted into the optical fiber groove 26 opened by the connecting column 25, so that the optical fiber head and the optical fiber groove 26 can be connected. The two first inclined blocks arranged on the two fixed blocks 30 are inserted into the first fixed groove 27, and the two protective blocks 22 are driven to move toward the connecting column 25 through the pulling force of the elastic component, thereby ensuring the stability of the installation between the optical fiber head and the optical fiber groove 26 opened on the connecting column 25.

[0025] The connecting mechanism also includes two clamping blocks 29 symmetrically arranged on the top and bottom sides of the connecting column 25. The two clamping blocks 29 are both inclined block structures, 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 to the inside of the connecting hole 2; two protective blocks 22 are penetrated into the connecting hole 2 and are provided on the end surface of one end and are respectively opposite to the positions of different clamping blocks 29; the two protective blocks 22 are penetrated into the connecting hole 2 and the two clamping blocks 29 are respectively penetrated in different second fixed grooves 28, and the two protective blocks 22 are close to each other.

[0026] The connecting mechanism also includes a disassembly component arranged on the optical fiber amplifier body 1, and the disassembly component includes a control rod 16 vertically and movably arranged on the side of the optical fiber amplifier body 1 on which the connecting hole 2 is opened, a control block 18 arranged in the optical fiber amplifier body 1 and whose end face is fixedly connected to the end of the control rod 16, a third limit spring 17 movably sleeved on the rod body of the control rod 16 and whose two ends are respectively connected to the inner wall of the optical fiber amplifier body 1 and the end face of the control block 18, and two disassembly bars 21 arranged vertically and parallelly and symmetrically on the end faces of two protective blocks 22 away from each other.

[0027] like Figure 1-4As shown, when the optical fiber head is removed from the connecting hole 2, the control rod 16 is pressed to move into the optical fiber amplifier body 1, driving the control block 18 to move in the optical fiber amplifier body 1, that is, driving the two disassembly bars 21 to move in the direction of the two fixed blocks 30, and the two fixed blocks 30 can be driven away from each other by the sides of the two disassembly bars 21 against the two fixed blocks 30, so that the first inclined block set on the fixed block 30 leaves the first fixed groove 27, so as to facilitate pulling the two protective blocks 22 to be removed in the connecting hole 2, and the optical fiber body 19 can be conveniently disassembled, and the two fixed blocks 30 will be driven to move into the buffer groove 4 under the action of the elastic component.

[0028] The elastic component includes a control board 20 which is vertically inserted into the buffer groove 4 and has a first control block 5 located on the top side of the optical fiber amplifier body 1 on the top, a second telescopic rod 14 which is horizontally inserted into the buffer groove 4 and has two ends respectively connected to an end face of the control board 20 away from the fixed block 30 and a groove wall of the buffer groove 4, and a second limit spring 15 which is movably sleeved on the rod body of the second telescopic rod 14.

[0029] like Figure 3 As shown, when the two fixed blocks 30 are located in the buffer groove 4, the second limit spring 15 is in a normal extension state. When the two protective blocks 22 are inserted into the connecting hole 2, the control board 20 is driven to move toward the connecting hole 2 through the first control block 5. At this time, the fixed block 30 set on the control board 20 is inserted into the connecting hole 2, and the two fixed blocks 30 are against the sides of the two protective blocks 22. At this time, the two fixed blocks 30 will rotate to rotate the torsion spring, and 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. The control board 20 will be pulled by the second limit spring 15 to move away from the connecting hole 2, and the two protective blocks 22 can be pulled to move into the connecting hole 2, thereby ensuring the stability of the optical fiber head inserted into the optical fiber groove 26.

[0030] A positioning block 8 is vertically arranged on the protective cover 7 near one end of the optical fiber amplifier body 1 and away from the rotational connection position with the optical fiber amplifier body 1. When the protective cover 7 is rotatably arranged on the top side of the optical fiber amplifier body 1, the positioning block 8 arranged on the protective cover 7 is penetrated into the positioning groove 3 provided on the top side of the optical fiber amplifier body 1. A moving block 12 is movably penetrated through the groove wall of the positioning groove 3, and a clamping block 13 fixedly arranged on the end face of the moving block 12 is penetrated in the positioning groove 3. The moving block 12 movably passes through the control board 20 and is penetrated in the buffer groove 4, and one end face of the moving block 12 penetrated in the buffer groove 4 is connected to the groove wall of the buffer groove 4 through a first telescopic rod 10. A first limit spring 11 is movably sleeved on the rod body of the first telescopic rod 10, and the first limit spring 11 is in a compressed state. A clamping hole 9 for the clamping block 13 to penetrate is opened on the positioning block 8.

[0031] When the protective cover 7 is rotated and set on the top side of the optical fiber amplifier body 1, the positioning block 8 set on the protective cover 7 is inserted into the positioning groove 3, and in the process of the positioning block 8 being inserted into the positioning groove 3, the positioning block 8 first presses against the clamping block 13 and moves into the buffer groove 4 to compress the first limit spring 11, and when the positioning block 8 moves to the relative position of the clamping hole 9 and the clamping block 13, the clamping block 13 will be driven to be inserted into the clamping hole 9 under the action of the first limit spring 11, so that the protective cover 7 can be placed on the top side of the optical fiber amplifier body 1.

[0032] A connecting rod is horizontally arranged in the buffer groove 4, and one end of the connecting rod is fixedly connected to the side of the moving block 12 and the other end is movable to pass through the outside of the optical fiber amplifier body 1. A second control block 6 is fixedly connected to the end of the connecting rod passing through the optical fiber amplifier body 1. By controlling the second control block 6 to move on the side of the optical fiber amplifier body 1, the moving block 12 can be used to drive the clamping block 13 to move into the buffer groove 4, and the clamping block 13 can be controlled to leave the clamping hole 9, thereby controlling the protective cover 7 to rotate on the top side of the optical fiber amplifier body 1.
