Description

Technical Field

[0001] This utility model relates to the field of soft waveguide assembly technology, and in particular to a flange for soft waveguide assemblies. Background Technology

[0002] Flexible waveguide components are important components for signal transmission in microwave communication, radar and other systems. They need to be connected and fixed by flanges. As a connection interface, the flange must not only ensure the stability of the structural installation, but also provide reliable sealing performance to prevent external moisture or contaminants from entering the waveguide and affecting the signal transmission quality.

[0003] In the existing technology, the flange is made of metal, while the part connected to the flexible waveguide needs to be transitioned and sealed by a flexible rubber sleeve. The connection between the flange and the rubber sleeve is usually achieved by adhesive bonding or simple interference fit. However, the thermal expansion coefficients of metal and rubber materials are quite different, and in working environments with vibration or pressure fluctuations, the simple bonding interface will generate stress concentration, resulting in micro cracks or delamination of the bonding layer.

[0004] This debonding phenomenon directly damages the airtightness of the connection, causing gas or moisture leakage. This not only seriously affects the electrical performance of the flexible waveguide assembly, but also significantly shortens the service life of the flange assembly. The existing flange structure lacks an effective mechanical interlocking mechanism to share the stress of the bonding interface and provide additional physical limits, thus failing to fundamentally guarantee the long-term reliability and sealing of the connection.

[0005] Therefore, this invention proposes a flange for soft waveguide assemblies to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems existing in the flanges used for flexible waveguide components, such as insufficient air tightness between the flange and the rubber sleeve, weak connection structure leading to delamination and air leakage, and limited service life, this utility model aims to provide a flange for flexible waveguide components with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a flange for a flexible waveguide assembly, comprising: a flange, a rubber sleeve, a limiting ring, an inner groove, a through hole, a positioning hole, a nut, a vertical protrusion, a horizontal protrusion, and an annular groove.

[0008] The flange has a fixed connection to a limit ring on its outer wall, and the outer wall has an inner groove, a through hole and multiple sets of positioning holes. The outer wall of the flange has multiple sets of nuts and annular grooves, and the outer wall of the rubber sleeve has multiple sets of vertical protrusions and multiple sets of horizontal protrusions.

[0009] Furthermore, the rubber sleeve and the flange are fixedly connected by a molding and vulcanization process. The extruded part of the inner wall of the rubber sleeve is combined with the inner groove opened in the middle of the outer wall of the flange by a snap-fit ​​method to form a horizontal mechanical limit. The right end of the rubber sleeve and the right ends of the vertical and horizontal protrusions on the outer wall of the rubber sleeve are combined with the annular groove opened on the outer wall of the flange by a snap-fit ​​method to form a vertical mechanical limit.

[0010] Preferably, the inner groove of the flange is an annular groove structure, and the cross-sectional shape can be rectangular or trapezoidal. The extruded part of the inner wall of the rubber sleeve forms a tight snap-fit ​​with the inner groove along the circumference. This full-circumferential interlocking structure greatly enhances the ability to resist axial pull-out.

[0011] Preferably, the annular groove of the flange is a groove with a rounded rectangular cross-section, and the right edge of the vertical and horizontal protrusions is designed with chamfers or rounded corners, which can form a tight fit with the inner wall of the annular groove, thus optimizing the smoothness of the assembly process and the firmness of the positioning.

[0012] Preferably, the vertical protrusions of the rubber sleeve are arranged at equal intervals along the outer wall of the rubber sleeve. The vertical protrusions form a ring structure that cooperates with the annular groove. After the rubber is filled in, the vertical protrusions can cooperate with the annular groove to strengthen the bond between the rubber sleeve and the flange, improve the adhesion of the sleeve, and prevent it from detaching.

[0013] Preferably, the horizontal protrusions of the rubber sleeve are annular protrusions surrounding the outer wall of the rubber sleeve. These continuous annular blocks form an annular structure that mates with the annular groove. After the rubber is filled in, this structure can mate with the inner groove, making the rubber sleeve more adhesive, less prone to detachment, and giving the product better airtightness.

[0014] Preferably, the through hole of the flange is a through hole whose central axis coincides with the central axis of the flange. The coaxial design facilitates the smooth flow of gas or fluid, reduces flow resistance, and simplifies the alignment and assembly process of the components.

[0015] Preferably, the positioning hole of the flange is a through hole structure, and the connection between the flange and the nut is a threaded connection. The nut can be designed as a nut with a flange or gasket to increase the contact area during fixing and provide a reliable and detachable fixing method for subsequent installation of the flange.

[0016] This utility model has the following beneficial effects: 1. This utility model uses a molding and vulcanization process to fix the flange and rubber sleeve together. A limiting ring and an inner groove are provided on the flange, and grooves in both vertical and horizontal directions are provided on the outer wall of the flange. These, along with the vertical and horizontal protrusions on the outer wall of the rubber sleeve, form a multi-limiting structure. This solves the problems of insufficient airtightness, weak connection, and easy delamination and air leakage when connecting the flange and rubber sleeve in existing systems. It significantly enhances the airtightness of the connection between the flange and the rubber sleeve, improves connection stability, and increases the adhesion of the product sleeve. The product maintains good stability even when inflated, preventing air leakage and making the sleeve less prone to detachment.

[0017] 2. This utility model solves the problem of insufficient structural strength and poor deformation resistance of existing flange connection components, which leads to limited service life, by forming a reinforcing rib structure through the annular groove of the flange after the product is sealed with glue, and by providing support through the vertical and horizontal protrusions on the outside of the rubber sleeve. It achieves the effect of improving the overall strength and support of the connection area and effectively extending the service life of the flange and the rubber sleeve.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model. Example

[0021] Please refer to Figures 1 to 4This utility model provides a flange for a flexible waveguide assembly, which aims to solve the structural defects of existing flanges when connected to flexible waveguides, such as insufficient air tightness of the rubber sealing sleeve, easy delamination and air leakage, and weak structural connection that affects service life.

[0022] Please refer to Figure 1 and Figure 2 The flange used for the flexible waveguide assembly includes a flange 3 and a rubber sleeve 1. The rubber sleeve 1 is fixedly connected to one side of the flange 3 by a molding and vulcanization process. The flange 3 serves as the core carrier and installation platform of the entire flange assembly, providing the connection interface with other components. The rubber sleeve 1 serves as a flexible sealing element connected to the flexible waveguide assembly, designed to provide excellent sealing and cushioning.

[0023] Furthermore, a limiting ring 6 is fixedly connected to the inner wall of the flange 3. The limiting ring 6 is used to ensure the precision and consistency of product manufacturing, avoid airtightness problems caused by molding and vulcanization deviations, and thus improve the stability of the connection between the flange 3 and the rubber sleeve 1. An inner groove 10 is opened in the middle of the inner wall of the flange 3. The inner groove 10 is an annular groove structure. After the rubber sleeve 1 is fixedly connected to the flange 3 through the molding and vulcanization process, an extruded part will be generated on the inner wall of the rubber sleeve 1. The extruded part is precisely designed to match the shape of the inner groove 10, so that the extruded part of the inner wall of the rubber sleeve 1 can be tightly inserted into the inner groove 10 inside the flange 3. The snap-fit ​​fixing method forms a continuous mechanical interlocking structure along the circumference of the inner groove 10, thereby completing the horizontal direction limiting of the rubber sleeve 1. It can effectively prevent the rubber sleeve 1 from sliding or detaching when subjected to axial force, greatly enhance the airtightness of the connection between the flange 3 and the rubber sleeve 1, significantly improve the sealing effect, and prevent potential degumming caused by material pressure or tension.

[0024] A through hole 8 is also provided in the middle of the inner wall of the flange 3. The through hole 8 is a through hole whose central axis coincides with the central axis of the flange 3. It is used for the flow of gas or fluid inside the soft waveguide assembly to ensure that it can pass smoothly through the flange connection area during operation.

[0025] The inner wall of the flange 3 has multiple sets of positioning holes 7. The positioning holes 7 are through holes and are evenly distributed at specific positions on the inner wall of the flange 3. They serve as the basis for subsequent precise connection and fixation with other components, providing standardized and reliable installation points.

[0026] The outer wall of flange 3 is provided with multiple sets of nuts 4, which correspond to the positioning holes 7. Nuts 4 and positioning holes 7 are connected by threads. The two work together to provide precise positioning and firm fixation for the subsequent installation of flange 3 with other soft waveguide components or other system components.

[0027] Please refer to Figure 1 , Figure 2 and Figure 4 The outer wall of the rubber sleeve 1 is provided with multiple sets of vertical protrusions 2. The vertical protrusions 2 are arranged at equal intervals along the outer wall of the rubber sleeve 1. These protrusions are perpendicular to the axial direction of the rubber sleeve 1, providing multi-point contact and limiting function, and enhancing the stability of the connection. At the same time, the outer wall of the rubber sleeve 1 is also provided with multiple sets of horizontal protrusions 9. The horizontal protrusions 9 are annular protrusions surrounding the outer wall of the rubber sleeve 1. These annular protrusions and the vertical protrusions 2 together form the complex geometry of the outer side of the rubber sleeve 1, which is intended to form a multi-dimensional and multi-layer mechanical interlock with the flange 3. The outer wall of the flange 3 is provided with an annular groove 5 in the middle. The annular groove 5 is a groove with a rounded rectangular cross-section. Its shape and size are precisely designed so as to cooperate with the protrusion structure on the rubber sleeve 1.

[0028] In the assembled state, when the rubber sleeve 1 is inserted into the flange 3, the right end of the rubber sleeve 1, as well as the right ends of the vertical protrusion 2 and the horizontal protrusion 9, will precisely engage with the annular groove 5 on the outside of the flange 3. This results in a tight engagement between the right ends of the vertical protrusion 2 and the horizontal protrusion 9 and the cross section of the annular groove 5. Consequently, the connection between the rubber sleeve 1 and the flange 3 is surrounded by the annular groove 5, forming a firm vertical limit and effectively preventing the rubber sleeve 1 from detaching or displacing in the radial or perpendicular axial direction.

[0029] As a preferred embodiment, in order to ensure that the rubber sleeve 1 can be accurately fixed on the flange 3 during the compression molding and vulcanization process, the depth and width of the limiting ring 6 can provide sufficient positioning support, so that the rubber material of the compression molding and vulcanization remains stable before curing. This provides accurate positioning guidance for the compression molding and vulcanization of the flange 3 and the rubber sleeve 1, avoids airtightness problems caused by position deviation, and improves the precision of product manufacturing.

[0030] As another preferred embodiment, the inner groove 10 is designed as an annular groove structure. The annular groove forms a continuous recess in the middle of the inner wall of the flange 3. The cross-sectional shape can be rectangular or trapezoidal to ensure that the extruded part of the inner wall of the rubber sleeve 1 can be uniformly and tightly inserted into the inner groove 10 in the circumference after molding and vulcanization. The full circumferential snap-fit ​​fixation provides an ultimate horizontal limiting effect. Even when the waveguide assembly is subjected to axial tension or compression force, it can firmly maintain the connection and significantly enhance the airtightness of the connection interface.

[0031] As another preferred embodiment, the annular groove 5 is designed as a groove with a rounded rectangular cross-section, which facilitates the smooth deformation and repositioning of the rubber sleeve 1 during insertion. It can also form a tight shape fit and engagement with the right ends of the vertical protrusion 2 and the horizontal protrusion 9. The edges of the vertical protrusion 2 and the horizontal protrusion 9 can be designed with chamfers or rounded corners to optimize the smoothness of the insertion process and the firmness of the engagement. The tight engagement structure provides a strong limiting effect in the vertical direction, further preventing the rubber sleeve 1 from displacing in the radial or vertical direction.

[0032] As a preferred embodiment, the vertical protrusions 2 are arranged at equal intervals along the outer wall of the rubber sleeve 1, which ensures the balanced distribution of support and limiting forces, avoids local stress concentration, and thus improves the overall stability and durability of the rubber sleeve 1. The specific number and spacing can be adjusted according to the support force and airtightness requirements required in actual applications to achieve the best performance.

[0033] As another preferred embodiment, the horizontal protrusion 9 is an annular protrusion surrounding the outer wall of the rubber sleeve 1, providing continuous radial support and limiting. Together with the vertical protrusion 2, it forms a three-dimensional limiting support network, ensuring that the connection interface of the rubber sleeve 1 inside the flange 3 can resist external stress from all directions. At the same time, it provides a solid foundation for the engagement of the annular groove 5, further consolidating the firmness of the connection.

[0034] As another preferred embodiment, the through hole 8 is designed as a through hole whose central axis coincides with the central axis of the flange 3, which ensures the smooth flow of gas or fluid through the flange connection area, reduces fluid resistance, simplifies the alignment requirements during assembly, and ensures the integration efficiency of the flange assembly in the entire waveguide system.

[0035] In a preferred embodiment, the positioning hole 7 is a through hole structure, which is machined on the inner wall of the flange 3 and is connected to the nut 4 by a thread. The nut 4 can be designed as a nut with a flange or a gasket to increase the contact area with the connecting parts. The threaded connection provides a reliable and detachable fixing means for the subsequent installation and fixing of the flange 3, such as fixing the flange 3 to other structures of the soft waveguide assembly or to a specific mounting base, ensuring the stability and reliability of the entire assembly after assembly.

[0036] Working principle: When the flange 3 and the rubber sleeve 1 are connected by compression molding and vulcanization, firstly, the limiting ring 6 on the inner wall of the flange 3 provides limiting guidance for the compression molding and vulcanization process, ensuring that the rubber sleeve 1 can be accurately fixed in the preset position of the flange 3. After the rubber sleeve 1 is cured, the extruded part of the inner wall of the rubber sleeve 1 will be tightly inserted into the inner groove 10 inside the flange 3. The inner groove 10 is an annular groove structure. This clamping and fixing forms a horizontal limiting on the rubber sleeve 1, effectively preventing the rubber sleeve 1 from sliding or detaching when subjected to axial force, and enhancing the airtightness of the connection. The outer wall of the rubber sleeve 1 is provided with multiple sets of vertical protrusions 2 and multiple sets of horizontal protrusions 9. After the rubber sleeve 1 is inserted into the flange 3, the right end of these protrusions will precisely engage with the annular groove 5 in the middle of the outer wall of the flange 3. The annular groove 5 is a groove with a rounded rectangular cross-section. This engagement makes the connection between the rubber sleeve 1 and the flange 3 surrounded by the annular groove 5, thereby forming a firm vertical limit and effectively preventing the rubber sleeve 1 from displacing in the radial or vertical direction. The vertical protrusions 2 and horizontal protrusions 9 not only provide mechanical limit, but also make the annular groove 5 form a firm reinforcing rib structure after the product is sealed. Moreover, the protrusions on the outside of the rubber sleeve 1 can provide good support compared with the smooth surface, enhancing the overall strength and stability of the connection. When gas or fluid is introduced into the through hole 8 in the middle of the inner wall of flange 3, the connection area between flange 3 and rubber sleeve 1 has a double limiting structure of inner groove 10 and annular groove 5. The through hole 8 is a through hole whose central axis coincides with the central axis of flange 3. The dual structure works together to greatly reduce the possible delamination and air leakage at the connection between rubber sleeve 1 and flange 3, ensuring the sealed transmission of fluid and improving the reliability of the component. In addition, the multiple sets of positioning holes 7 on the inner wall of flange 3 are through hole structures, which are threadedly connected to the multiple sets of nuts 4 on the outer wall of flange 3. This provides precise positioning and firm fixing effect for the subsequent installation of flange 3 with other soft waveguide components. Through the above mechanism, the problems of insufficient airtightness, weak connection and limited service life in the prior art are effectively solved, the airtightness of the connection between flange 3 and rubber sleeve 1 is enhanced, and the service life is improved.
