Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber isolators, in particular to a component for improving the stability of optical fiber isolators. Background Art

[0002] Fiber isolators mainly use the Faraday effect of magneto-optical crystals to isolate reflected light, allowing light to only be transmitted in a single direction. This passive magneto-optical device rotates the polarization state of the input light by a certain angle through the Faraday rotation effect in the magneto-optical material, making the reflected light orthogonal to the incident light in polarization state, thereby isolating the reflected light.

[0003] Fiber optic isolators can solve the reflection problem between optical devices, but existing fiber optic isolators do not have the function of automatic heat dissipation, and cannot be automatically opened and closed. If the internal hardware temperature is too high, it is likely to cause unstable operation. Therefore, a component that improves the stability of the fiber optic isolator is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a component for improving the stability of an optical fiber isolator.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a component for improving the stability of the optical fiber isolator, including an isolator body and a stabilizing frame, the bottom bolts in the stabilizing frame are connected to the isolator body, both sides of the top of the isolator body are embedded with side plates, both sides of the top front and back of the stabilizing frame are installed with temperature controllers, and the bottom of the temperature controller is electrically connected to an infrared thermometer.

[0006] Preferably, a transmission plug is clamped inside the side plate, and a heat dissipation sleeve frame is clamped outside the transmission plug.

[0007] Preferably, the front side of the temperature controller is electrically connected to a fan controller, and a fan unit is installed at the bottom of the fan controller.

[0008] Preferably, a middle connection block is welded to the middle of the top end of the isolator body, and a partition plate is clamped to the bottom of the top of the isolator body near the middle connection block.

[0009] Preferably, a top window is opened on the top of the isolator body, and the top of the isolator body is divided into four groups of top windows by a middle connecting block and a partition.

[0010] Preferably, driving motors are installed on both sides of the middle joint block, and the ends of the driving motors are drivingly connected to driving couplings, and the ends of the driving couplings are connected to the side plates.

[0011] Preferably, the inside of the top window is slidably connected with a folding plate layer, a driving coupling passes through the middle of the folding plate layer, a sleeve is clamped at the top connection of the folding plate layer, the sleeve is slidably connected to the front and back sides of the top window, and the driving coupling passes through the sleeve and is threadedly connected.

[0012] Beneficial Effects

[0013] In the utility model, the stabilizing frame will protect the isolator body, and the four groups of infrared thermometers on the top of the stabilizing frame will measure the temperature of the front and back sides of the top of the isolator body in real time. The infrared thermometer is an existing device that can measure the temperature of opaque objects. The infrared thermometer in this device mainly measures the temperature of the hardware in the isolator body through the outer shell. The four groups of temperature measurement components detect four different positions. After the temperature value is detected, the detected value will be transmitted to the temperature controller. The temperature controller here is a control computer for temperature comparison. The temperature controller will compare the detected temperature value with the temperature limit value. When the detected value exceeds the limit value, it will transmit an open signal to the fan controller and the corresponding drive motor through the built-in MCU, so as to facilitate the cooling of the detection area.

[0014] In the utility model, after receiving the command signal transmitted by the relative temperature controller, the driving motor will control the driving shaft to rotate clockwise. When the driving shaft rotates clockwise, the sleeve will continuously slide in the direction of the driving motor. When the sleeve slides in the direction of the driving motor, it will drive the folding plate layer to fold up as shown in the figure. After the folding plate layer is folded up, the top window at the corresponding position will be exposed. At this time, the fan unit started from the top can dissipate heat for the hardware at the corresponding position in the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0025] Reference Figure 1-5 A component for improving the stability of an optical fiber isolator includes an isolator body 1 and a stabilizing frame 2. The isolator body 1 is connected to the bottom bolts of the stabilizing frame 2. Side plates 10 are embedded on both sides of the top of the isolator body 1. Temperature controllers 7 are installed on both sides of the front and back of the top of the stabilizing frame 2. The bottom of the temperature controller 7 is electrically connected to an infrared temperature detector 8.

[0026] First, the stabilizing frame 2 will protect the isolator body 1. The four groups of infrared thermometers 8 on the top of the stabilizing frame 2 will measure the temperature of the front and back sides of the top of the isolator body 1 in real time. The infrared thermometer 8 is an existing device that can measure the temperature of opaque objects. In this device, the infrared thermometer 8 mainly measures the temperature of the hardware in the isolator body 1 through the outer shell. The four groups of temperature measurement components are used to detect four different positions. After the temperature value is detected, the detected value will be transmitted to the temperature controller 7. The temperature controller 7 here is a control computer for temperature comparison. A set of temperature limit values ​​will be set in advance in the temperature controller 7. The temperature controller 7 will compare the detected temperature value with the temperature limit value. When the detected value exceeds the limit value, it will transmit a start signal to the fan controller 5 and the corresponding drive motor 14 through the built-in MCU.

[0027] The front side of the temperature controller 7 is electrically connected to the fan controller 5 , and the bottom side of the fan controller 5 is equipped with a fan unit 6 .

[0028] The fan controller 5 and the drive motor 14 are both equipped with receiving ports specifically for receiving command signals. After receiving the signal, the fan controller 5 will control the fan unit 6 to start fanning the bottom. It should be noted that each group of temperature controllers 7 corresponds to the nearest fan controller 5 and the nearest drive motor 14 to the bottom. Specific embodiment 2:

[0030] Reference Figure 1-5 The transmission plug 3 is connected to the inside of the side plate 10, and the heat dissipation sleeve 11 is connected to the outside of the transmission plug 3. The heat dissipation sleeve 11 on the transmission plug 3 is made of heat-conducting material and can conduct away the temperature generated when the transmission plug 3 is working.

[0031] A middle connecting block 4 is welded to the middle of the top of the isolator body 1 , and a partition plate 12 is clamped to the bottom of the top of the isolator body 1 near the middle connecting block 4 .

[0032] A top window 13 is provided on the top of the isolator body 1 , and four groups of top windows 13 are separated on the top of the isolator body 1 by the middle connecting block 4 and the partition plate 12 .

[0033] A driving motor 14 is installed on both sides of the middle connecting block 4 , and the end of the driving motor 14 is drivingly connected to a driving coupling 15 , and the end of the driving coupling 15 is connected to the side plate 10 .

[0034] The inside of the top window 13 is slidably connected with a folding plate layer 9, a driving coupling 15 passes through the middle of the folding plate layer 9, a sleeve 16 is clamped at the top connection of the folding plate layer 9, the sleeve 16 is slidably connected to the front and back sides of the top window 13, and the driving coupling 15 passes through the sleeve 16 and is threadedly connected.

[0035] After receiving the instruction signal transmitted by the relative temperature controller 7, the driving motor 14 controls the driving shaft 15 to rotate clockwise. When the driving shaft 15 rotates clockwise, the sleeve 16 will continuously slide in the direction of the driving motor 14. When the sleeve 16 slides in the direction of the driving motor 14, it will drive the folding plate layer 9 to fold up. Figure 4 As shown, after the folding plate layer 9 is folded up, the top window 13 at the corresponding position will be exposed. At this time, the fan unit 6 started from the top can dissipate heat for the hardware at the corresponding position in the equipment. After an interval of five minutes, the driving motor 14 will automatically control the driving coupling 15 to rotate clockwise, so that the sleeve 16 slides outward. When the sleeve 16 slides outward, the folding plate layer 9 will be pulled open to cover the top window 13.

[0036] In summary:

[0037] 1. The stabilizing frame 2 will protect the isolator body 1. The four sets of infrared thermometers 8 on the top of the stabilizing frame 2 will measure the temperature of the front and back sides of the top of the isolator body 1 in real time. The infrared thermometer 8 is an existing device that can measure the temperature of opaque objects. In this device, the infrared thermometer 8 mainly measures the temperature of the hardware in the isolator body 1 through the outer shell. The four sets of temperature measurement components are used to detect four different positions. After the temperature value is detected, the detected value will be transmitted to the temperature controller 7. The temperature controller 7 here is a control computer for temperature comparison. A set of temperature limit values ​​will be set in advance in the temperature controller 7. The temperature controller 7 will compare the detected temperature value with the temperature limit value. When the detected value exceeds the limit value, it will transmit an open signal to the fan controller 5 and the corresponding drive motor 14 through the built-in MCU.

[0038] 2. After receiving the command signal transmitted by the relative temperature controller 7, the driving motor 14 controls the driving shaft 15 to rotate clockwise. When the driving shaft 15 rotates clockwise, the sleeve 16 will continue to slide in the direction of the driving motor 14. When the sleeve 16 slides in the direction of the driving motor 14, it will drive the folding plate layer 9 to fold up. Figure 4 As shown, after the folding plate layer 9 is folded up, the top window 13 at the corresponding position will be exposed. At this time, the fan unit 6 started from the top can dissipate heat for the hardware at the corresponding position in the equipment. After an interval of five minutes, the driving motor 14 will automatically control the driving coupling 15 to rotate clockwise, so that the sleeve 16 slides outward. When the sleeve 16 slides outward, the folding plate layer 9 will be pulled open to cover the top window 13.
