Description

Technical Field

[0001] This application belongs to the field of satellite manufacturing auxiliary tooling, and in particular relates to a tooling for assembling and disassembling a coaxial radio frequency connector. Background Technology

[0002] The high degree of integration (modularization) of satellite equipment brings many advantages (such as weight reduction, volume reduction, and shorter internal wiring), but it also leads to a high concentration and excessively small spacing of connectors at their external interfaces on the device panel. For RF connectors such as SMA (SubMiniature version A) and SSMA (Sub-SubMiniature version A) that require precise torque installation, it is impossible to apply effective and uniform torque to the RF connector using standard installation tools to ensure connection reliability within the limited space. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a tooling for assembling and disassembling a coaxial radio frequency connector, so as to solve at least one of the above technical problems.

[0004] To achieve the above-mentioned technical objectives, this application provides a tooling for assembling and disassembling a coaxial radio frequency connector, including a force transmission component. The force transmission component includes a main body, a receiving portion and a force transmission portion extending axially along the main body. The force transmission portion is connected to the main body through the receiving portion. At least one accommodating cavity is formed in the receiving portion and the force transmission portion. Openings communicating with the accommodating cavity are provided on the sidewalls of both the force transmission portion and the receiving portion. The force transmission portion is used to clamp the coaxial radio frequency connector of the satellite, the receiving portion is used to receive the radio frequency wire of the coaxial radio frequency connector, and the main body is used to receive the force transmitted by a standard installation tool.

[0005] In one embodiment, the receiving cavity is formed by the connecting cavity in the force transmission part and the receiving cavity in the receiving part, and the receiving cavity and the connecting cavity are coaxially arranged with the main body.

[0006] In one embodiment, the connecting cavity is polygonal in shape, the receiving cavity is cylindrical in shape, and the diameter of the connecting cavity is larger than the corresponding diameter of the receiving cavity.

[0007] In one embodiment, the main body includes a connecting block and a force-applying part. The connecting block is connected to the receiving part, and the force-applying part is located on the side of the connecting block away from the receiving part. The force-applying part is used to cooperate with a standard installation tool.

[0008] In one embodiment, the connecting block is solid, and the outer contour of the force-applying part is polygonal.

[0009] In one embodiment, the outer surface of the force-applying part is provided with a chamfer, the radius of which is 0.2mm to 0.5mm.

[0010] In one embodiment, the dimensional tolerance threshold of the force-applying part is the same as the dimensional tolerance threshold of the force-transmitting part.

[0011] In one embodiment, the width of the opening is 6mm to 9mm.

[0012] In one embodiment, the force transmission element has a strength of 1000 MPa or more and a hardness of 60 HRC or more.

[0013] In one embodiment, a standard mounting tool is also included, and the force is transmitted to the coaxial RF connector sequentially through the standard mounting tool and the force transmission element.

[0014] By adopting the above technical solution, this application has the following beneficial effects:

[0015] This application, through the concept of forming a communicating accommodating cavity in at least the receiving portion and the force transmission portion of the force transmission member, and having openings communicating with the accommodating cavity on the side walls of both the force transmission portion and the receiving portion, offers an advantage over the prior art. When the force transmission portion clamps onto the coaxial RF connector of the satellite from the opening, and the RF cable of the coaxial RF connector is inserted into the accommodating cavity from the opening, an external force is applied to one end of the force transmission member. Driven by the external force, the force transmission member rotates the coaxial RF connector, thereby disassembling or installing the coaxial RF connector. This is beneficial in solving the problem of not being able to apply effective and uniform torque to the coaxial RF connector using standard installation tools in a confined space.

[0027] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of this application, and not all of them. Based on the description of this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise expressly specified and limited, the terms "set," "install," "connect," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms based on the specific circumstances.

They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar properties, not to indicate or imply relative importance or a specific order.

[0031] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0032] Currently, to reduce the weight, size, and circuit connection distance of satellite equipment, multiple functional units (such as satellite management, reference clock generation, GPS signal reception and processing, and integrated data processing) are typically highly integrated into a single physical device (such as a chassis or module) to achieve high integration (modularization) of satellite equipment. However, this also results in connectors at external interfaces being highly concentrated and spaced too closely together on the device panel. For RF connectors requiring precise torque installation, such as SMA (Sub-Miniature Version A) and SSMA (Sub-Sub-Miniature A), the limited space makes it impossible to apply effective and uniform torque to the RF connector using standard installation tools to ensure connection reliability.

[0033] In order to solve the problems existing in the existing technology, it is necessary to improve the existing tooling structure.

[0034] Please see Figures 1 to 4 The first aspect of this application provides a tooling for disassembling and assembling a coaxial RF connector, used for disassembling or installing a coaxial RF connector for a satellite. It should be noted that the coaxial RF connector referred to herein is an electromechanical integrated component used to connect to cables or instruments to achieve electrical connection or separation in the RF signal transmission path, such as SMA, SSMA, etc. It is worth mentioning that the coaxial RF connector referred to herein includes RF lines (such as RF coaxial cables) connected to or integrally formed with the coaxial RF connector.

[0035] like Figure 2 , Figure 3 As shown, the tooling for assembling and disassembling the coaxial RF connector includes a force transmission component 1, used to apply an effective and uniform force or torque to the coaxial RF connector of the satellite. Preferably, the force transmission component 1 is made of steel with high strength, toughness, and fatigue resistance, such as 50CrV4 spring steel. Compared with the prior art, this is beneficial in ensuring that the strength of the force transmission component 1 is above 1000MPa and the hardness is above 60HRC, such as a strength of 1000MPa and a hardness of 60HRC, or a strength of 1200MPa and a hardness of 70HRC, etc. This is beneficial in ensuring that the mechanical properties of the manufactured force transmission component 1 meet the requirements to achieve the assembly and disassembly of the coaxial RF connector.

[0036] Overall, the force transmission component 1 is shaped like a straight rod. The force transmission component 1 includes a main body 11, a receiving portion 12, and a force transmission portion 13. The main body 11 has a cylindrical structure (such as a rod or bar) for receiving forces transmitted via standard installation tools (such as open-end torque wrenches, socket torque wrenches, adjustable torque wrenches, etc.). The receiving portion 12 extends axially along the main body 11 and is used to receive the radio frequency (RF) wire of the coaxial RF connector. The force transmission portion 13 also extends axially along the main body 11 and is connected to or integrally formed with the main body 11 via the receiving portion 12, for clamping the satellite's coaxial RF connector. Preferably, the axial length of the receiving portion 12 is greater than the axial length of the force transmission portion 13 to receive the RF wire or a portion of the RF wire of the coaxial RF connector, thereby overcoming operational interference when the RF wire applies torque.

[0037] It should be noted that, in order to address the problem of not being able to apply effective and uniform torque directly to the coaxial RF connector using standard mounting tools within a confined space, a communicating accommodating cavity 14 is formed within at least the receiving portion 12 and the force transmitting portion 13, and openings 15 communicating with the accommodating cavity 14 are formed on the sidewalls of both the force transmitting portion 13 and the receiving portion 12. Specifically, the openings 15 are formed on the sidewalls of the receiving portion 12 and the force transmitting portion 13. Preferably, the length of the opening 15 in the axial direction of the main body 11 is greater than or equal to 60 mm, such as 70 mm, 90 mm, 100 mm, 106 mm, etc., and the width S of the opening 15 (e.g., ...) is... Figure 4 The diameter (as shown in the diagram) is 6mm to 9mm, such as 6mm, 6.54mm, 8mm, 9mm, etc., to allow sufficient clearance for the installation and removal of the coaxial RF connector. Thus, compared to existing technologies, within a limited tool space, this application, through the configuration of the force transmission component 1, increases the lever arm of the torque, overcoming the insufficient operating space required for torque transmission. Furthermore, by providing a communicating receiving cavity 14 and opening 15 on the receiving portion 12 and the force transmission portion 13 of the force transmission component 1, when the force transmission portion 13 clamps onto the satellite's coaxial RF connector from the opening 15, and the RF cable of the coaxial RF connector is inserted into the receiving cavity 14 from the opening 15, an external force is applied to the main body 11. Driven by this external force, the force transmission portion 13 rotates the coaxial RF connector, thereby allowing for the removal or installation of the coaxial RF connector. This facilitates the easy application of effective and uniform torque to the coaxial RF connector by the operator through the force transmission component 1, ensuring the reliability of the electrical connection.

[0038] Furthermore, the receiving cavity 14 is jointly formed by the connecting cavity 131 within the force-transmitting portion 13 and the receiving cavity 121 within the receiving portion 12. The connecting cavity 131 extends along the length direction of the force-transmitting portion 13, making the force-transmitting portion 13 hollow. The receiving cavity 121 extends along the length direction of the receiving portion 12, making the receiving portion 12 also hollow. Preferably, the receiving cavity 121 and the connecting cavity 131 are coaxially arranged with the main body portion 11, and the connection between the receiving cavity 121 and the connecting cavity 131 is smoothly connected. It should be noted that the shape of the connecting cavity 131 matches the outer contour of the coaxial RF connector, and the shape of the receiving cavity 121 matches the outer contour of the RF line of the coaxial RF connector. For example, as... Figures 2 to 4 As shown, the receiving cavity 121 is cylindrical, and the connecting cavity 131 is hexagonal, but it is not limited to this. That is, in other embodiments, the connecting cavity 131 may also be dodecagonal, etc. Preferably, the diameter of the connecting cavity 131 is larger than the corresponding diameter of the receiving cavity 121.

[0039] Furthermore, for ease of force application, the main body 11 includes a connecting block 111 and a force-applying part 112. The connecting block 111 is connected to the receiving part 12. The force-applying part 112 is located on the side of the connecting block 111 away from the receiving part 12 and is used for mating with a standard installation tool. Preferably, the main body 11 is solid to improve the strength of the force transmission member 1. The force-applying part 112 is integrally formed with the connecting block 111, and the outer contour of the force-applying part 112 is adapted to the corresponding standard installation tool. For example, as... Figure 2 , Figure 3 As shown, the outer contour of the force-applying part 112 is hexagonal, but it is not limited to this.

[0040] Preferably, the dimensional tolerance threshold of the force-applying part 112 is the same as the dimensional tolerance threshold of the force-transmitting part 13. That is, the difference between the upper and lower deviations at the force-applying part 112 is the same as the difference between the upper and lower deviations at the force-transmitting part 13.

[0041] Furthermore, to increase the contact area between the force-applying part 112 and the standard installation tool during connection, the outer surface of the force-applying part 112 is chamfered. Preferably, the radius of the chamfer is 0.2mm to 0.5mm. This helps ensure that the quality of the manufactured force transmission component 1 meets the requirements.

[0042] Furthermore, the tooling for assembling and disassembling the coaxial RF connector also includes a standard installation tool (not shown in the figure). This standard installation tool is detachably connected to the force transmission component 1, such as an open-end torque wrench, a socket torque wrench, or an adjustable torque wrench. Thus, when the standard installation tool is connected to the coaxial RF connector via the force transmission component 1, the external force applied to the standard installation tool (such as human force) is sequentially transmitted to the coaxial RF connector through the standard installation tool and the force transmission component 1. This makes it easier to convert the external force into the torque required to rotate the coaxial RF connector.

[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
