Abstract
Description
Technical Field
[0001] This invention relates to the field of waveguide connection technology, and more specifically, to a waveguide connection structure and method. Background Technology
[0002] High-power microwave transmission typically employs waveguides (to reduce loss), and their connection configurations currently predominantly use flanged waveguides. These waveguides transmit electromagnetic waves through metal tubes, effectively reducing energy loss while ensuring signal transmission efficiency. Flanged waveguides mainly consist of a straight waveguide tube, flanges, and fasteners. The flanges are installed at both ends of the waveguide and connected to adjacent waveguide sections or other components via screws, forming a stable mechanical interface. This flange design ensures a stable and reliable connection of the waveguide. Flanged waveguides are characterized by their robust structure, high durability, and ability to operate in harsh environments.
[0003] like Figure 1 As shown, the typical interface structure of a traditional flange-connected waveguide has the following drawbacks: 1) It uses a connection method with four screws evenly distributed around the waveguide. In many equipment environments, the two screws at the bottom are almost inaccessible, making it almost impossible to install them; especially in confined environments such as airborne.
[0004] 2) Because of the use of screws, it takes a lot of time to put on and take off the screws, and screwdrivers or special tools are required, which makes the operation very inconvenient.
[0005] 3) Due to the use of screws for fastening, there is a frequent risk of the upper and lower screws falling off, and it is very troublesome to find these fallen screws in environments such as airborne environments.
[0006] 4) Screws may come loose, posing a risk to application. If glue is applied, it will be difficult to disassemble later.
[0007] 5) Since a horizontal screwdriver is required for removing and installing screws, a relatively large operating space is needed.
[0008] Adopting such Figure 1The structure shown involves the flanges at both ends moving relative to each other under the guidance of locating pins until the waveguide end faces are tightly fitted together. At this point, the screws are tightened one by one to secure the flanges, ensuring a tight fit between the waveguide end faces. The good end face machining quality and the stable, uniform pressure generated by the screws result in a tight connection between the waveguide ports. This tight connection is extremely important in high-frequency transmission; even the smallest gap can affect microwave transmission. However, even with the pre-guiding alignment of the locating pins, uneven force distribution on the screws during tightening can occur due to torque control and the tightening sequence. This uneven force distribution prevents the waveguide end faces from achieving an ideal tight fit, leaving gaps in the waveguide ports and affecting electrical transmission.
[0009] like Figure 2 As shown, in some confined spaces, flanged waveguide ports that require tools to tighten from different directions can pose challenges to product space design. Even if the waveguide connection ports can be placed within the product, tools cannot be inserted into the intended positions from all four locations when tightening screws, not to mention automated production lines using power tools, where limited space restricts tool application. Summary of the Invention
[0010] The technical problem to be solved by the present invention is to provide a waveguide connection structure and method; The solution adopted by this invention to solve the technical problem is: on the one hand: This invention provides a waveguide connection structure, including a housing that is plugged into a waveguide socket, a threaded sleeve that is coaxially fitted on the outside of the housing and rotatably fitted with the housing, a sliding sleeve that is fitted on the outside of the threaded sleeve and the waveguide socket and plugged into the outside of the waveguide socket, and an elastic element that is fitted on the outside of the threaded sleeve and located between the threaded sleeve and the sliding sleeve; the threaded sleeve is screwed into the waveguide socket. An annular cavity for mounting an elastic element is formed between the outer sides of the sliding sleeve and the threaded sleeve. The sliding sleeve is rotatably fitted with the threaded sleeve and slides along the axial direction of the threaded sleeve.
[0011] In some possible implementations, an anti-rotation tooth is provided on the inner side of the sliding sleeve and at one end near the waveguide socket, which engages with the anti-rotation groove provided on the outer side of the waveguide socket.
[0012] In some possible implementations, an anti-rotation locking point is provided on the inner side of the sliding sleeve and at the end away from the waveguide socket; an anti-rotation locking groove is provided on the outer side of the screw sleeve to cooperate with the anti-rotation locking point.
[0013] In some possible implementations, the anti-rotation slot includes an axial slot arranged along the axial direction of the threaded sleeve and a radial slot connected to the end of the axial slot away from the waveguide socket and forming an L-shaped structure, wherein the center of the radial slot is on the axis of the threaded sleeve.
[0014] In some possible implementations, an annular boss is provided inside the sliding sleeve and between the anti-rotation tooth and the anti-rotation locking point; the elastic element is located between the annular boss and the anti-rotation locking point.
[0015] In some possible implementations, the anti-rotation jamming points are in two sets and are symmetrically arranged, and the anti-rotation jamming slots are arranged in a one-to-one correspondence with the anti-rotation jamming points.
[0016] In some possible implementations, the housing includes a plug-in boss with a locating pin installed at one end and a locating keyway provided on the outside, a rotating part disposed on the side of the plug-in boss away from the locating pin and fitted inside a threaded sleeve, and a base disposed on the side of the rotating part away from the plug-in boss and located on the outside of the threaded sleeve. The waveguide socket is provided with a plug interface that engages with the plug-in boss, and a pin hole is provided at the bottom of the plug interface that communicates with the plug interface and engages with the positioning pin; a positioning key is provided on the inner side of the plug interface for use with the positioning keyway.
[0017] In some possible implementations, an annular groove is provided on the outer side of the rotating part, and an annular groove is provided on the inner side of the threaded sleeve to cooperate with the annular groove and form an annular mounting cavity, and an annular retaining ring is installed in the annular mounting cavity.
[0018] In some possible implementations, the threaded sleeve includes a rotating sleeve fitted on the outside of the housing and having an annular groove on its inner side, an anti-rotation part disposed on the side of the rotating sleeve near the waveguide socket and having an internal thread on its inner side, and a sleeve disposed on the side of the anti-rotation part away from the rotating part. An outer edge is provided on the outer surface of the sleeve at the end away from the anti-rotation part, and the annular boss is located between the outer edge and the anti-rotation part; The anti-rotation slot is located on the outside of the anti-rotation part.
[0019] on the other hand: This invention provides a waveguide connection method, based on the waveguide connection structure described above, specifically including the following steps: The control sleeve moves away from the waveguide socket, the elastic element changes from the initial state to the compressed state, and the rotation of the sleeve causes the sleeve to engage with the threaded sleeve. Insert the waveguide socket into the housing, and rotate the screw sleeve to make the housing and the waveguide socket fit together on one side. The rotating sleeve returns to its original position, no longer locked in place by the screw sleeve. Under the action of elasticity, the sleeve slides towards the side closer to the waveguide socket and inserts into the outer side of the waveguide socket, completing the connection.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention achieves the positive pressure required for the connection between the waveguide socket and the housing end face through the screw engagement of the screw sleeve and the waveguide socket, eliminating the need to tighten multiple screws and avoiding the impact of unbalanced force on the electrical connection. This invention limits the relative rotation between the threaded sleeve and the waveguide socket by setting a sliding sleeve and an elastic element to cooperate, ensuring a reliable connection between the threaded engagement, thereby enabling the waveguide connection to reliably and stably make electrical contact with the port connection surface even in a vibration environment.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0023] The present invention will now be described in detail.
[0024] like Figures 1-11 As shown: A waveguide connection structure includes a housing 1 that is inserted into a waveguide socket 10, a threaded sleeve 2 that is coaxially fitted on the outside of the housing 1 and rotatably fitted with the housing 1, a sliding sleeve 3 that is fitted on the outside of the threaded sleeve 2 and the waveguide socket 10 and inserted into the outside of the waveguide socket 10, and an elastic member 4 that is fitted on the outside of the threaded sleeve 2 and located between the threaded sleeve 2 and the sliding sleeve 3; the inner surface of the threaded sleeve 2 is threaded into the outer surface of the waveguide socket 10. An annular cavity for installing the elastic element 4 is formed between the outer sides of the sliding sleeve 3 and the screw sleeve 2; the housing 1 serves as a waveguide plug and is plugged into the waveguide socket 10. The sliding sleeve 3 is rotatably engaged with the threaded sleeve 2 and is also slidably engaged with the threaded sleeve 2 along the axial direction of the threaded sleeve 2.
[0025] When assembling the waveguide socket 10 with the present invention, firstly, control the sliding sleeve 3 to move away from the waveguide socket 10 and engage with the outer side of the screw sleeve 2. At this time, the elastic element 4 will be compressed. Then, insert the waveguide socket 10 into the housing 1. Then, rotate the screw sleeve 2 around its axis and drive the sliding sleeve 3 to rotate, so that the waveguide socket 10 moves towards the housing 1. After the waveguide socket 10 and the housing 1 are in contact and fit together on their respective sides, control the sliding sleeve 3 to no longer engage with the screw sleeve 2. The elastic element 4 will return from the compressed state to the initial state, so that the sliding sleeve 3 moves away from the waveguide socket 10 and engages with the outer side of the waveguide socket 10. This effectively restricts the rotation of the sliding sleeve 3 around its axis and achieves a reliable connection.
[0026] Furthermore, the elastic element 4 is a compression spring.
[0027] In some possible implementations, an anti-rotation tooth 32 is provided on the inner side of the sliding sleeve 3 and at one end near the waveguide socket 10, which engages with the anti-rotation groove 101 provided on the outer side of the waveguide socket 10. The anti-rotation tooth 32 and the anti-rotation groove 101 are arranged in a one-to-one correspondence. After the waveguide socket 10 contacts and fits against the housing 1, the anti-rotation tooth 32 will be inserted into the corresponding anti-rotation groove 101, thereby effectively restricting the relative rotation between the sliding sleeve 3 and the waveguide socket 10.
[0028] In some possible implementations, in order to effectively limit the relative rotation between the sliding sleeve 3 and the screw sleeve 2, and to ensure that the sliding sleeve 3 and the screw sleeve 2 can be effectively engaged during the assembly of the waveguide socket 10 and the housing 1, so as to prevent the sliding sleeve 3 from moving along its axial direction and interfering with the assembly of the waveguide socket 10 and the housing 1, an anti-rotation locking point 31 is provided on the inner side of the sliding sleeve 3 and at the end away from the waveguide socket 10; an anti-rotation locking groove 21 is provided on the outer side of the screw sleeve 2 to cooperate with the anti-rotation locking point 31; the anti-rotation locking groove 21 includes an axial groove arranged along the axial direction of the screw sleeve 2 and a radial groove connected to the end of the axial groove away from the waveguide socket 10 and forming an L-shaped structure, the center of the radial groove being on the axis of the screw sleeve 2; Specifically, before assembly, the control sleeve 3 moves away from the waveguide socket 10, causing the anti-rotation locking point 31 to move from the axial groove to the radial groove. After the anti-rotation locking point 31 moves axially into the radial groove, the sleeve 3 is rotated, causing the anti-rotation locking point 31 to rotate and enter the radial groove. The radial groove restricts the movement of the anti-rotation locking point 31 along the axial direction of the threaded sleeve 2, thereby achieving the locking and limiting of the sleeve 3 and the threaded sleeve 2. At this time, the compression spring will be in a compressed state, and then the waveguide socket 10 can be inserted into the housing 1. The rotation of the threaded sleeve makes the waveguide socket 10 contact and fit with the housing 1. After the two come into contact and fit together, rotate the sliding sleeve 3 so that the anti-rotation locking point 31 moves from the radial groove to the axial groove side. Under the elastic force provided by the compression spring, the sliding sleeve 3 is driven to move along the axial groove towards the side closer to the waveguide socket 10 until the anti-rotation tooth 32 is inserted into the anti-rotation tooth groove 101 provided on the outside of the waveguide socket 10. At this time, the anti-rotation locking point 31 will still be located in the axial groove and the compression spring will still be in a compressed state. Since the anti-rotation locking point 31 is located in the axial groove and the anti-rotation tooth 32 is inserted into the anti-rotation tooth groove 101, the rotation of the sliding sleeve 3 around its axis is effectively restricted. Since the compression spring is still in a compressed state at this time, it will apply an elastic force to the side of the waveguide socket 10 on the threaded sleeve 2 and the housing 1, ensuring a reliable connection between the threaded waveguide socket 10 and the threaded sleeve 2. This allows the end face of the waveguide socket 10 and the housing 1 to achieve reliable and stable electrical contact even under vibration.
[0029] In some possible implementations, an annular boss 33 is provided inside the sliding sleeve 3 and between the anti-rotation tooth 32 and the anti-rotation locking point 31; the elastic element 4 is located between the annular boss 33 and the anti-rotation locking point 31.
[0030] Specifically, the anti-rotation locking points 31 are in two sets and are symmetrically arranged on a 180° symmetrical plane, and the anti-rotation locking slots 21 are arranged in a one-to-one correspondence with the anti-rotation locking points 31.
[0031] In some possible embodiments, the housing 1 includes a plug-in boss with a positioning pin 11 installed at one end and a positioning keyway 12 provided on the outside, a rotating part provided on the side of the plug-in boss away from the positioning pin 11 and fitted inside the screw sleeve 2, and a base provided on the side of the rotating part away from the plug-in boss and located on the outside of the screw sleeve 2; the positioning keyway 12 is provided with an opening on the side away from the rotating part; the plug-in boss, the rotating part, and the base are coaxially arranged; Specifically, the waveguide socket 10 is provided with a plug interface that engages with the plug-in boss, and a pin hole 103 is provided at the bottom of the plug interface that communicates with the plug interface and engages with the positioning pin 11; a positioning key 102 is provided on the inner side of the plug interface that engages with the positioning keyway 12. A gap is formed between the plug-in boss and the screw sleeve 2. The outer side of the plug-in interface in the waveguide socket 10 will be located in the gap and screwed into the screw sleeve 2. When the waveguide socket 10 is inserted into the housing 1, the insertion boss will be fitted into the insertion interface, the positioning pin 11 will be located in the pin hole 103, and the positioning key 102 will be located in the positioning keyway 12, thereby effectively positioning the waveguide socket 10 and the housing 1, which serves as the waveguide plug.
[0032] In some possible implementations, an annular groove 13 is provided on the outer side of the rotating part, and an annular groove is provided on the inner side of the threaded sleeve 2 to cooperate with the annular groove 13 and form an annular mounting cavity. An annular retaining ring 5 is installed in the annular mounting cavity. The setting of the annular retaining ring 5 will effectively prevent the threaded sleeve 2 from falling off. The setting of the annular retaining ring 5 will also transmit the elastic force of the compression spring to the housing 1 after assembly, so that the contact surface between the housing 1 and the waveguide socket 10 always remains in contact.
[0033] Specifically, the cross-section of the annular slot 13 is stepped, including a slot one located near the waveguide socket and a slot two connected to slot one and located on the side of slot one away from the waveguide socket. The inner diameter of slot one is larger than the inner diameter of slot two. After assembly, the annular slot 13 will be located in slot one.
[0034] In some possible implementations, the screw sleeve 2 includes a rotating sleeve fitted on the outside of the housing 1 and having an annular groove on its inner side, an anti-rotation part disposed on the side of the rotating sleeve near the waveguide socket 10 and having an internal thread on its inner side, and a sleeve disposed on the side of the anti-rotation part away from the rotating part. An outer edge 22 is provided on the outer side of the sleeve at the end away from the anti-rotation part, and the annular boss 33 is located between the outer edge 22 and the anti-rotation part; The anti-rotation slot 21 is provided on the outside of the anti-rotation part; the rotating seat, the anti-rotation part, and the sleeve are coaxially connected; the outer diameter of the anti-rotation part is larger than the outer diameter of the sleeve, and the side of the anti-rotation part near the sleeve serves as the contact surface of the elastic element. Specifically, when the end face of the waveguide socket 10 contacts and fits against the end face of the housing 1, the sliding sleeve 3 is rotated and rotated from the radial groove to the axial groove. When the anti-rotation locking point 31 rotates to the point where the axial groove and the radial groove are connected, the elastic element 4 will recover from the compressed state to the initial state. Under the elastic force, it will drive the sliding sleeve 3 to move closer to the waveguide socket 10. When the annular boss 33 contacts the outer edge 22, the elastic element 4 is still in the compressed state. At this time, the sliding sleeve 3 will no longer be able to move axially closer to the waveguide socket 10. The anti-rotation tooth 32 will mesh with the anti-rotation tooth groove 101. At the same time, the anti-rotation locking point 31 will be located in the axial groove and at the end of the axial groove closer to the waveguide socket 10. The present invention, through the cooperation of the anti-rotation locking point 31 and the axial groove, and the cooperation of the anti-rotation tooth 32 and the anti-rotation tooth groove 101, prevents relative rotation between the threaded sleeve 2 and the waveguide socket 10. The compression spring, which is still in a compressed state, will apply an elastic force to the housing 1 towards the waveguide socket 10 through the threaded sleeve 2 to the annular retaining ring 5, thereby ensuring a reliable connection between the internal thread on the inner side of the threaded sleeve 2 and the external thread of the waveguide socket 10.
[0035] Furthermore, in order to facilitate the sliding sleeve 3 to be fitted onto the outside of the screw sleeve 2, multiple sets of opening slots are provided on one end of the sleeve with an outer edge 22 and along its circumference, and the multiple sets of opening slots are equally spaced; when assembling the sliding sleeve 3 and the screw sleeve 2, by shrinking the end of the sleeve with an outer edge 22 inward, the annular boss 33 can be fitted onto the side of the outer edge 22 away from the waveguide socket 10.
[0036] Furthermore, the outer side of the rotating sleeve has a polygonal structure, specifically a regular tetrahedron or a regular hexagon. When controlling the rotation of the screw sleeve 2, a wrench can be fitted on the outer side of the rotating sleeve to tighten reliably in one direction at once. Compared with the existing technology, it is not necessary to lock in four positions, which greatly facilitates the spatial structure design of the product. Furthermore, waveguide ports 100 are respectively provided on the side of the housing 1 near the waveguide socket 10 and on the side of the waveguide socket 10 near the housing 1, with two sets of waveguide ports 100 being provided correspondingly.
[0037] Furthermore, the locating pins 11 and locating keys 102 are in two sets; the planes on which the two sets of locating keys 102 are located are perpendicular to the planes on which the two sets of locating pins 11 are located.
[0038] on the other hand: This invention provides a waveguide connection method, based on the waveguide connection structure described above, specifically including the following steps: Control the sliding sleeve 3 to move away from the waveguide socket 10, and the elastic element 4 located in the annular cavity changes from the initial state to the compressed state. Rotate the sliding sleeve 3 to make the sliding sleeve 3 engage with the screw sleeve 2. Specifically, the anti-rotation jamming point 31 moves along the sliding sleeve 3 and moves towards the radial groove. When the sliding sleeve 3 is rotated, the anti-rotation jamming point 31 will move around the axis of the sliding sleeve 3 and enter the radial groove. At this time, the anti-rotation jamming point 31 will engage with the radial groove, thereby restricting the movement of the sliding sleeve 3 along the axis of the sliding sleeve 3 and realizing the engagement with the screw sleeve 2. Insert the waveguide socket 10 into the housing 1, and rotate the screw sleeve 2 to make the housing 1 and the waveguide socket 10 close to each other on one side. Among them, the control positioning key 102 is located in the positioning keyway 12, the plug-in boss is fitted in the plug-in interface, and the positioning pin 11 will be located in the pin hole 103 to realize the guidance of the assembly of the two. Specifically, firstly, the positioning key 102 will enter the positioning keyway 12. After the two work together to guide the alignment, the insertion will continue. During alignment, the two positioning pins 11 and the positioning holes are also pre-aligned to ensure the smooth insertion and accurate positioning of the subsequent insertion. Subsequently, the rotating sleeve is rotated so that the bottom of the insertion interface and the insertion boss come into contact and fit together. When the rotating sleeve rotates, the sliding sleeve 3 and the screw sleeve 2 will be engaged due to the snap-fit. The sliding sleeve 3 will not affect the normal screwing. At the same time, due to the cooperation between the positioning pin 11 and the pin hole 103 and the cooperation between the positioning key 102 and the positioning keyway 12, when the screw sleeve 2 rotates, the waveguide socket 10 can only move along the axial direction of the screw sleeve 2. This allows the waveguide port 100 after the waveguide socket 10 and the housing 1 are fitted together to fit as required. Then, the rotating sleeve 3 is reset, and the sleeve 3 is no longer engaged with the screw sleeve 2. Under the elastic action of the compression spring, the sleeve 3 slides towards the side closer to the waveguide socket 10 and inserts into the outer side of the waveguide socket 10 to complete the connection.
[0039] Specifically, rotating the sliding sleeve 3 causes the anti-rotation locking point 31 to move from the radial groove to the axial groove side. Under the elastic tension of the compression spring, the sliding sleeve 3 moves closer to the waveguide socket 10, and the anti-rotation locking point 31 slides into the axial groove until the anti-rotation tooth 32 and the anti-rotation tooth groove 101 are engaged. At this time, the sliding sleeve 3 cannot rotate relative to the waveguide socket 10 under the action of the anti-rotation tooth 32, and the anti-rotation locking point 31 is located in the axial groove, which also prevents the sliding sleeve 3 from rotating relative to the threaded sleeve 2. By preventing the threaded sleeve 2 from rotating relative to the socket waveguide, a reliable connection between the internal thread of the threaded sleeve 2 and the external thread of the socket waveguide is ensured. Conversely, the waveguide socket 10 can be disassembled from the housing 1.
[0040] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
