Description

Technical Field

[0001] The present invention relates to the technical field of optical signal connection, and in particular to a waveguide vertical optical coupling structure. Background Art

[0002] At present, the main methods for realizing vertical coupling of "waveguide-fiber" on optical signal boards include photolithography of 45° inclined mirrors on waveguides, photolithography of spherical concave mirrors, embedding of vertical steering coupling elements, soft waveguide method and waveguide grating method.

[0003] In the technical method of vertical coupling, MT optical connectors are often used to achieve vertical coupling between waveguide and optical fiber. The specific operation method is to insert the MT optical connector on the substrate to achieve the vertical coupling state between the waveguide and the optical fiber.

[0004] Existing MT optical connectors are generally installed by inserting two guide pins through round holes. However, this simple plug-in installation has many disadvantages. On the one hand, it is easy to cause the MT optical connector to fall off, which greatly reduces the stability of the connection; on the other hand, it may also cause poor contact of the optical fiber, which seriously affects the stable transmission of the optical signal.

[0005] In addition, in the prior art, a cladding is usually provided on the substrate. This cladding is often adhered to the substrate by an adhesive, and the 45-degree hollow-core optical fiber and the waveguide are both located in the cladding. During long-term use, the temperature of the environment itself and the temperature generated by the long-term operation of the optical fiber may cause the optical fiber to expand to a certain extent. This expansion can easily cause the bonding part between the cladding and the substrate to separate, destroying the stability of the overall structure. When the temperature drops, the MT optical connector may not be able to make good contact with the 45-degree hollow-core optical fiber, which ultimately causes the optical signal to be unable to continue to be transmitted, causing great trouble to practical applications. Therefore, it is necessary to design a waveguide vertical optical coupling structure to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the prior art and propose a waveguide vertical optical coupling structure. The structure can stably connect the MT optical connector 13 with the substrate, so that the optical fiber and the waveguide can be vertically coupled, and the waveguide can be prevented from being separated from the substrate. At the same time, in hot weather, the environment where the waveguide is located is always in a low temperature state, thereby avoiding the situation where the waveguide cannot be stably contacted with the MT optical connector due to thermal expansion, thereby ensuring the stability of optical signal propagation.

[0018] Compared with the prior art, by setting the limit blocks and the limit holes, after the MT optical connector is installed, the pressure plate moves downward and the multiple limit blocks enter the corresponding limit holes, thereby limiting the MT optical connector, making it difficult for the MT optical connector to be separated from the substrate;

[0021] Compared with the prior art, through the setting of the electromagnet, the downward inclination angle of the nozzle can be adjusted according to the temperature, thereby adjusting the rotation speed of the spiral tube, so that the efficiency of heat exchange between the water in the water tank and the airflow will change according to the change of temperature, ensuring that when the temperature is very good, the airflow temperature in the spiral tube can also be quickly reduced to a predetermined value, thereby ensuring that the working environment of the waveguide is always in a constant temperature state.

[0036] The cooling component includes a circulation fan 27, a water tank 24 and an adjustment box 28 arranged on the cover plate 2. The water tank 24 is filled with water. The air outlet of the circulation fan 27 is connected to the front space of the groove. A rotary joint 26 is installed on the right side of the water tank 24. The inner walls on the left and right sides of the water tank 24 are rotatably connected with short tubes 31. The adjacent sides of the two short tubes 31 are fixedly connected with a spiral tube 25.

A rack 39 is fixedly connected to the rear side of the slider, and a wire is connected to the rear side of the resistor plate 6. An electron is provided on the substrate 1, and the electron, two resistor plates 6, the conductive block 5, the circulating fan 27 and the electromagnet 36 form a through the wire. In a circuit, the higher the temperature, the longer the memory wire 4 is stretched, so that the resistance of the two resistor plates 6 connected to the circuit will decrease, and the current passing through the electromagnet 36 and the circulating fan 27 will increase, so that the circulating gas flow rate will increase, and at the same time, the attraction of the electromagnet 36 to the slider will increase, and the upward rotation angle of the nozzle 35 will increase, so that the airflow ejected by the nozzle 35 can better blow the impeller 34 to rotate, so that the impeller 34 drives the rotating rod, the short tube 31 and the spiral tube 25 to increase the rotation speed, and the water disturbance rate in the water tank 24 will increase, thereby improving the efficiency of heat exchange.

[0038] The functional principle of the present invention can be explained by the following operation mode: firstly, the cladding 22 with the waveguide, the supporting optical fiber and the forty-five-degree hollow optical fiber is adhered to the inner bottom of the groove by an adhesive, and then the circular holes 43 on the two MT optical connectors 13 are aligned with the corresponding guide pins 44 and inserted, so that the guide pins 44 pass through the corresponding circular holes 43, so that the optical fiber and the waveguide are vertically coupled;

[0039] After the MT optical connector 13 is installed, the staff rotates the knob 9, and the knob 9 drives the first threaded rod 10 to rotate. Since the first threaded rod 10 is in a meshing state with the threaded sleeve 12, the threaded sleeve 12 drives the pressure plate 21 to move downward and press on the cladding 22. In the process of the first threaded rod 10 rotating, since the two first bevel gears are meshed with the second bevel gear, the first threaded rod 10 drives the two transmission rods 15 to rotate during the rotation, and then drives the corresponding two second threaded rods 18 to rotate through the transmission assembly 17. In the process of the two second threaded rods 18 rotating, the corresponding two limit blocks 19 will move relative to each other, so that the limit blocks 19 enter the limit groove, and the MT optical connector 13 is limited, so as to avoid the situation that the MT optical connector 13 is separated from the base and the optical signal cannot be transmitted;

[0040] At room temperature, the memory wire 4 is in a contracted state, the conductive block 5 is not in contact with the two resistor plates 6, and the circulating fans 27 and 27 are both in a power-off state. When the external temperature is too high, due to the characteristics of the memory wire 4, the memory wire 4 will be stretched and restored, and the higher the temperature, the longer the stretched length of the memory wire 4.

[0041] After the memory metal wire 4 is stretched, the conductive block 5 will move backward and contact the two resistor plates 6. At this time, the thermostatic component 29 and the circulating fan 27 are powered on and run. The operation of the thermostatic component 29 ensures that the water in the water tank 24 is always at room temperature. The operation of the circulating fan 27 causes the gas in the groove to pass through the adjustment box 28 and the spiral tube 25 and then be blown into the groove by the circulating fan 27. When the airflow flows in the spiral tube 25, it will exchange heat with the water in the water tank 24, so that the gas temperature is reduced, and then the environment around the waveguide is at room temperature, so as to avoid the situation where the position of the connection with the optical fiber is offset due to the thermal expansion of the waveguide, thereby ensuring the stable transmission of the optical signal.

[0042] During the process of gas circulation and cooling, the airflow sprayed from the nozzle 35 will spray toward the impeller 34, and the impeller 34 will drive the rotating rod to rotate. Since the first gear 32 and the second gear 33 are in a meshing state, the rotation of the rotating rod drives the short tube 31 on the left to rotate, thereby causing the spiral tube 25 to rotate, disturbing the water in the water tank 24, improving the heat exchange efficiency between the airflow and the water in the spiral tube 25, so that the temperature of the airflow flowing out of the spiral tube 25 can always be kept at a constant temperature;

[0043] When the outside temperature is low, the distance that the conductive block 5 moves backward is small, so that the length of the two resistor plates 6 connected to the circuit is short, the resistance of the two resistor plates 6 connected to the circuit is large, and the current passing through the electromagnet 36 is small, so that the attraction of the electromagnet 36 to the slider is small. At this time, the nozzle position of the nozzle 35 is tilted downward, and the ejected air flow blows to the area of ​​the impeller 34 close to the rotating rod, so that the impeller 34 drives the rotating rod to rotate at a slower speed;

[0044] When the outside temperature is high, the distance that the conductive block 5 moves backward is large, the resistance of the two resistor plates 6 connected to the circuit is small, and the current passing through the electromagnet 36 is large, so that the slider and the rack 39 move a large distance, so that the nozzle 35 rotates upward, and the ejected airflow blows to the area of ​​the impeller 34 away from the rotating rod, so that the impeller 34 drives the rotating rod to rotate at a slower speed, so that the rotation speed of the spiral tube 25 can be changed according to the change of the outside temperature, so that in high temperature weather, the heat exchange efficiency between the airflow and water in the spiral tube 25 can be increased with the increase of temperature;

[0045] It is worth mentioning that, as the resistance of the two resistor plates 6 connected to the circuit decreases, the wind speed generated by the circulating fan 27 will also increase. Thus, the increase in the rotation speed of the spiral tube 25 can keep the circulating airflow at a lower temperature as much as possible, thereby avoiding thermal expansion of the waveguide.

[0046] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
