Description

Technical Field

[0001] This invention belongs to the field of waveguide connection technology, and more specifically, relates to a waveguide quick connector for fast, low-loss connection of two waveguide ports. Background Technology

[0002] Traditional waveguide connection methods, such as Figure 1 As shown, the two waveguides 1 that need to be connected first align the screw holes 201 of their respective flanges 2 at the connection end, and then tighten the two flanges 2 at the connection end by screwing screws (not shown) into the screw holes 201. First, when connecting waveguides, it is necessary to ensure that each screw is tightened. If it is not tightened, it will cause serious leakage. Second, this waveguide connection method requires tightening a lot of screws, and the inconvenience of tightening them leads to a long assembly time. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and propose a waveguide fast connector to achieve fast and tight connection of input and output waveguides.

[0004] To achieve the above-mentioned objective, the waveguide fast connector of the present invention is characterized by comprising:

[0005] Both input and output waveguide structures have standard rectangular waveguides running through them, and both are three-step structures along the waveguide axis. The first and second steps are cuboids, and the width and height of the cuboid of the second step are both greater than those of the cuboid of the first step. The third step is a cylinder, and its diameter is greater than the width and height of the cuboid of the second step.

[0006] Two identical flange ring structures, with the same dimensions as a standard flange. For each flange ring structure, there is a circular hole in the middle of one side, with the same diameter and thickness as the third-step cylinder of the input and output waveguide structure, but it does not penetrate the flange ring structure. The other side has a rectangular hole in the middle, with the same width and height as the second-step cuboid of the input and output waveguide structure, and it penetrates through the circular hole.

[0007] Left-hand and right-hand waveguide support structures are used to fix the two input and output waveguide structures respectively. They are cylindrical structures with external threads on the cylindrical surface. The external threads of the left-hand and right-hand waveguide support structures are opposite in direction and mirror-symmetrical with respect to their end faces. The center of the cylindrical surface of the left-hand and right-hand waveguide support structures has a through rectangular hole with the same size as the first step of the input and output waveguides. There are four through holes with threads on the cylindrical surface near one end of the cylinder, which are used to fix the input and output waveguide structures inserted into the rectangular holes. There are four pin holes evenly distributed on the cylindrical surface near the other end of the cylinder for pin connection of the left-hand and right-hand waveguide support structures and to ensure that the ports of the two input and output waveguides are aligned.

[0008] The bidirectional threaded support connection structure is a nut structure, with its internal thread consisting of two sections of internal threads in opposite directions. The size of the internal thread is consistent with the size of the external thread of the left-hand and right-hand waveguide support structures.

[0009] A pin is inserted into each of the four pin holes on the right-hand waveguide support structure. Then, one end of the pin is inserted into a threaded hole on the side of the bidirectional threaded support connection structure that matches the external thread of the right-hand waveguide support structure. Then, one end of the left-hand waveguide support structure with a pin hole is inserted into the threaded hole on the other side of the bidirectional threaded support connection structure. During insertion, the rectangular holes of the left-hand and right-hand waveguide support structures are aligned, and the pins inserted into the four pin holes on the left-hand waveguide support structure are inserted into the four pin holes on the right-hand waveguide support structure. Finally, the bidirectional threaded support connection structure is rotated to move the left-hand and right-hand waveguide support structures toward the middle to achieve connection. The length of the pin is less than twice the depth of the pin hole and greater than the sum of the pin depth and the thickness of the bidirectional threaded support connection structure, i.e., the length of the thread.

[0010] The first step segment of an input / output waveguide structure is inserted from one side of the circular hole in a flange ring structure and then into the rectangular hole in a left-handed waveguide support structure. Finally, the input / output waveguide structure inserted into the rectangular hole is secured with rubber-headed screws. The first step segment of another input / output waveguide structure is inserted from one side of the circular hole in another flange ring structure and then into the rectangular hole in a right-handed waveguide support structure. Finally, the input / output waveguide structure inserted into the rectangular hole is secured with rubber-headed screws.

[0011] The objective of this invention is achieved as follows.

[0012] This invention relates to a waveguide quick connector that uses a bidirectional threaded support connection structure to connect left-hand and right-hand waveguide support structures. In use, the two input / output waveguide structures are inserted into the left-hand and right-hand waveguide support structures respectively, and then secured with rubber-headed screws to the rectangular holes, completing the quick connection of the waveguides. This method only requires ensuring no slippage in the horizontal direction; even if some screws are not tightened, leakage will not occur. Furthermore, only four rubber-headed screws are needed, and the radial tightening is convenient, significantly reducing assembly time and achieving a quick and tight connection of the input and output waveguides.

[0013] Furthermore, the present invention is a controllable spacing waveguide assembly with a relatively simple overall structure, which is easy to process. Compared with the conventional method of connecting two waveguide ports using flanges, it has the advantages of supporting the connection of different waveguide materials and supporting non-contact low-loss transmission.

[0023] The specific embodiments of the present invention will now be described with reference to the accompanying drawings to enable those skilled in the art to better understand the invention. It should be particularly noted that in the following description, detailed descriptions of known functions and designs that might obscure the main content of the invention will be omitted here.

[0024] Figure 2 This is a schematic diagram of the overall structure of the waveguide fast connector of the present invention.

[0025] In this embodiment, as Figure 2 As shown, the waveguide quick connector of the present invention includes two input and output waveguide structures 101 and 102 located at the left and right ends, two identical flange ring structures 201 and 202, left-hand and right-hand waveguide support structures 301 and 302, and a bidirectional threaded support connection structure 4 located in the middle. The specific structure is described below.

[0026] In this embodiment, as Figure 3 , 4As shown, both input and output waveguide structures 101 and 102 have standard rectangular waveguides running through them. They are all in a three-step shape along the waveguide axis. The first and second steps are both cuboids, and the width and height of the cuboid of the second step are both greater than those of the cuboid of the first step. The third step is a cylinder, and its diameter is greater than the width and height of the cuboid of the second step.

[0027] In this embodiment, the first step is a cuboid with a width of 6mm, a height of 5.2mm, and a length of 7mm; the second step is a cuboid with a width of 7mm, a height of 6mm, and a length of 7mm; and the third step is a cylinder with a radius of 4.6mm. In this embodiment, whether the input / output waveguide structure is used as an input or output depends on the specific circumstances. Figure 3 The input-output waveguide structure shown is an input waveguide structure. It has a right photonic crystal structure and a matching structure designed near the waveguide port of the third step. The specific structure is not the subject of this invention and will not be described in detail here. Figure 4 The input and output waveguide structures shown are used as the output waveguide structures.

[0028] In this embodiment, the two identical flange ring structures 201 and 202 have the same dimensions as the standard flange. For each flange ring structure, such as Figure 5 As shown, there is a circular hole 2011 in the middle of one side (labeled as a flange ring structure 201). The diameter of the hole is the same as the diameter and thickness of the third stepped cylinder of the input and output waveguide structure, but it does not penetrate the flange ring structure 201. There is a rectangular hole 2012 in the middle of the other side. Its width and height are the same as the second stepped cuboid of the input and output waveguide structure, and it penetrates through the circular hole.

[0029] In this embodiment, the flange ring structure 201 is used to connect the test instrument and the input / output waveguide structure. The circular hole 2011 has a radius of 4.6 mm, and on one side there is a rectangular hole 2012 with a width of 7 mm and a height of 6 mm, so that the test instrument and the input / output waveguide structure can be tightly connected.

[0030] Left-handed and right-handed waveguide support structures 301 and 302 are used to fix the two input and output waveguide structures 101 and 102, respectively. In this embodiment, as shown... Figure 6 , 7As shown, the structure is cylindrical with external threads on the cylindrical surface. The external threads of the left-hand and right-hand waveguide support structures 301 and 302 are opposite in direction and mirror-symmetrical with respect to their end faces. The left-hand and right-hand waveguide support structures 301 and 302 have through rectangular holes 3011 and 3021 at the center of their circular surfaces. The size of these holes is the same as the first step of the input and output waveguides. There are four through holes 3012 and 3022 on the cylindrical surface near one end of the cylinder. These holes are threaded and fitted with rubber-headed screws to fix the input and output waveguide structures inserted into the rectangular holes. There are four pin holes 3013 and 3023 evenly distributed on the circular surface near the other end of the cylinder. These are used to connect the left-hand and right-hand waveguide support structures with pins and to ensure that the two input and output waveguide ports are aligned.

[0031] In this embodiment, the left-hand and right-hand waveguide support structures are cylinders with a radius of 7.5 mm, and the rectangular hole in the middle is 6 mm wide and 5.2 mm high.

[0032] In this embodiment, the bidirectional threaded support connection structure 4 is a nut structure, and its internal thread consists of two sections of internal threads in opposite directions. The size of the internal thread is consistent with the size of the external threads of the left-hand and right-hand waveguide support structures 301 and 302.

[0033] In this embodiment, as Figure 8 As shown, the bidirectional threaded support connection structure 4 is used to connect the left-hand and right-hand waveguide support structures 301 and 302. It is generally a cuboid with a width of 19mm, a height of 19mm, and a length of 12mm, with an internal hole of 7.5mm radius. It has left-hand and right-hand internal threads on both sides. In this embodiment, each of the four sides of the cuboid has a through rectangular hole 401 for inserting a standard thickness metal sheet to control the spacing between the input and output waveguide structures. Each of the four chamfered edges has a pair of through holes 402 with internal threads, which are fitted with rubber-headed screws of the same size to fix the bidirectional threaded support connection structure to the left-hand and right-hand waveguide support structures 301 and 302.

[0034] Figure 9 This is a schematic diagram of the assembly process of the waveguide quick connector of the present invention.

[0035] In this embodiment, as Figure 9 As shown, the assembly process is as follows:

[0036] Step 1: Insert a pin 5 into each of the four pin holes on the right-hand waveguide support structure 302;

[0037] Step 2: Then insert one end of the inserted pin 5 into the threaded hole on the side where the external thread of the bidirectional threaded support connection structure 4 and the right-hand waveguide support structure 302 are the same;

[0038] Step 3: Then, insert the end of the left-hand waveguide support structure 301 with the pin hole into the threaded hole on the other side of the bidirectional threaded support connection structure 4. During insertion, the rectangular holes of the left-hand and right-hand waveguide support structures 301 and 302 are aligned, and the pins inserted into the four pin holes on the left-hand waveguide support structure are inserted into the four pin holes on the right-hand waveguide support structure. Finally, rotate the bidirectional threaded support connection structure 4 to move the left-hand and right-hand waveguide support structures 301 and 302 toward the middle to achieve connection. The length of the pin 5 is less than twice the depth of the pin hole and greater than the sum of the pin depth and the thickness of the bidirectional threaded support connection structure 4, i.e., the length of the thread.

[0039] Step 4: Insert the first stepped segment of one input / output waveguide structure 101 into one side of the circular hole of a flange ring structure 201, and insert the first stepped segment of another input / output waveguide structure 102 into one side of the circular hole of another flange ring structure 202.

[0040] Step 5: Insert the components into the rectangular holes of the left-hand and right-hand waveguide support structures 301 and 302 respectively. Finally, use rubber-tipped screws to fix the input and output waveguide structures 101 and 102 inserted into the rectangular holes.

[0041] Existing waveguide quick connectors are only suitable for waveguides made of materials with good ductility. If the waveguide has poor ductility, such as a silicon waveguide, connecting it to a metal waveguide may cause the silicon waveguide to break. In this embodiment, the entire structure is made of metal, which facilitates screw installation; it is also compatible with the flange assembly structure currently used in the market, saving costs.

[0042] This invention relates to a rapid connection structure for waveguide ports, primarily used for rapid connection of input and output waveguides and testing of non-contact waveguide transmission. In this embodiment, the invention is a non-contact rectangular waveguide connection structure loaded with a photonic crystal. This structure utilizes photonic crystals of different structures to constrain electromagnetic waves of different structures, maintaining good transmission characteristics even if the waveguide is not fully connected due to rapid assembly.

[0043] Although the illustrative specific embodiments of the present invention have been described above to enable those skilled in the art to understand the invention, it should be understood that the invention is not limited to the scope of the specific embodiments. For those skilled in the art, various changes are obvious as long as they are within the spirit and scope of the invention as defined and determined by the appended claims, and all inventions utilizing the concept of the present invention are protected.
