Abstract

This invention relates to the field of airtight connector technology, providing a floating blind mating method and airtight connector assembly for high-temperature, high-irradiation environments. The floating blind mating method is as follows: the plug assembly or socket assembly can float in two mutually perpendicular directions within a plane perpendicular to the insertion / removal direction to accommodate radial deviations between the plug assembly and socket assembly; one of the plug assembly and socket assembly is fixed, while the other is driven by a drive mechanism to move along the insertion / removal direction, thereby achieving the insertion or separation of the plug assembly and socket assembly. This invention enables reliable alignment and smooth insertion / removal even with a certain radial offset between the plug and socket through floating self-adaptation, significantly improving the environmental adaptability, operational fault tolerance, and connection reliability of the mating process. It fundamentally avoids risks such as pin damage, insertion / removal jamming, and connection failure caused by misalignment, and is suitable for long-term stable operation and maintenance requirements under extreme conditions.

Description

Technical Field

[0001] This invention relates to the field of hermetically sealed connector technology, and more specifically, to a floating blind mating method and hermetically sealed connector assembly for use in high-temperature and high-irradiation environments. Background Technology

[0002] Hermetic connectors, as critical nodes for signal and energy transmission, play an irreplaceable role in extreme environments such as nuclear reactor internal monitoring, high-temperature experimental devices, deep space exploration spacecraft, and high-energy physics facilities. These environments typically exhibit harsh characteristics such as prolonged high temperatures (above several hundred degrees Celsius), strong particle or electromagnetic radiation, complex thermal cycling, and limited maintenance conditions. Therefore, connectors must not only possess excellent high-temperature stability, radiation resistance, and long-term hermeticity, but also ensure connection reliability under limited operating space and harsh conditions.

[0003] Currently, hermetic connector assemblies used in the aforementioned extreme environments mostly employ rigid alignment and fixed connection designs. To achieve high-fidelity signal transmission and hermeticity requirements, the plug and socket are typically precisely aligned and secured using precision-machined keyways, guide pins, or threaded locking mechanisms. This design ensures good performance under ideal installation conditions.

[0004] However, in practical engineering applications, especially in the extreme environments of high temperature and strong radiation, existing technologies have extremely low tolerance for insertion and removal errors and poor environmental adaptability. Traditional rigid designs have extremely stringent requirements for instantaneous coaxiality and parallelism during installation. During long-term operation, structural thermal deformation caused by differences in the thermal expansion coefficients of different materials, or creep and swelling of materials under strong radiation, can lead to slight but critical offsets in the socket installation position on the equipment panel. In addition, vibration and deformation of the installation platform itself, as well as minor installation deviations, are difficult to avoid. Once there is a misalignment or angular tilt between the central axis of the plug and socket, misalignment between the pins and the socket is very likely to occur, resulting in jamming, scratching, or even damage to expensive precision pins during insertion and removal. In severe cases, components cannot be connected or disconnected at all, making equipment maintenance or module replacement extremely difficult or even impossible, resulting in huge operational risks and economic losses. Summary of the Invention

[0005] The purpose of this invention is to provide a floating blind mating method and an airtight mating assembly for use in high-temperature and high-irradiation environments.

[0006] This invention is achieved through the following technical solution: A floating blind-mating method for high-temperature and high-irradiation environments enables a plug assembly or socket assembly to float in two mutually perpendicular directions within a plane perpendicular to the insertion / removal direction, in order to accommodate radial deviations between the plug assembly and the socket assembly; one of the plug assembly and the socket assembly is fixed, while the other is driven by a drive mechanism to move along the insertion / removal direction, thereby achieving the insertion or separation of the plug assembly and the socket assembly.

[0007] Furthermore, the float of the plug assembly or socket assembly shall not be less than ±5mm.

[0008] This invention also provides a floating blind-mating airtight connector assembly for high-temperature, high-irradiation environments, employing any of the above-described floating blind-mating methods, comprising a plug assembly, a socket assembly, and a base; one of the plug assembly and the socket assembly is fixedly connected to the base, and the other is slidably connected to the base and connected to a driving mechanism; the plug assembly or socket assembly is provided with a floating support structure, which includes a support frame, a floating mounting plate, and a floating support rod; the support frame is connected to the base, and the plug assembly or socket assembly is fixedly mounted on the floating mounting plate; the support frame is provided with a plurality of limiting posts, the limiting posts passing through floating holes on the floating mounting plate and having retaining rings at their ends, the diameter of the floating holes being larger than the diameter of the limiting posts; the floating support rod is connected to the perimeter of the support frame through an elastic structure and abuts against the floating mounting plate.

[0009] Furthermore, one of the plug assembly and the socket assembly is provided with a mating guide post, and the other is provided with a mating guide sleeve that mates with the mating guide post, and the end of the mating guide sleeve is provided with a tapered guide portion.

[0010] Furthermore, the elastic structure includes a support sleeve, a threaded sleeve, and a spring. The support sleeve is connected to the support frame by screws and has an open end. The threaded sleeve is connected to the open end of the support sleeve by threads. The floating support rod slides through the end of the threaded sleeve and has a stop at its inner end that can abut against the end of the threaded sleeve. The spring is located inside the threaded sleeve and applies axial thrust to the floating support rod.

[0011] Furthermore, the support frame and the limiting post are connected by rivets passing through the center of the limiting post, and the retaining ring is limited by the rivets.

[0012] Furthermore, the elastic structure includes a guide inner sleeve, an adjusting outer sleeve, and a spring. The adjusting outer sleeve is slidably inserted through the outside of the support frame and has an open inner end. The guide inner sleeve is slidably inserted through the inside of the open end of the adjusting outer sleeve. The floating support rod is slidably inserted through the end of the threaded sleeve and has a stop at its inner end that can abut against the end of the guide inner sleeve. The spring is located inside the guide inner sleeve and applies axial thrust to the floating support rod. Each side of the support frame is provided with an adjustment mechanism, which includes a fixed plate, a guide rod, an adjustment plate and an adjustment screw. There are at least two guide rods, one end of which is fixedly connected to the support frame. The fixed plate is fixedly connected to the other end of the guide rod. The adjustment plate is slidably connected to the guide rod. Each adjustment sleeve on the same side of the support frame is fixedly connected to the adjustment plate. The adjustment screw is rotatably connected between the fixed plate and the support frame, and the adjustment screw and the adjustment plate are connected by a thread.

[0013] Furthermore, the drive mechanism includes a lead screw, a nut seat, and a knob. One of the plug assembly and the socket assembly, which is slidably connected to the base, is located on a sliding support. The nut seat is located at the bottom of the sliding support. The lead screw is rotatably located at the top of the base. The nut seat and the lead screw are threaded together. The knob is located at one end of the lead screw.

[0014] Furthermore, a limiting seat is provided on the base between the plug assembly and the socket assembly, and the limiting seat can abut against the sliding support seat.

[0015] Furthermore, a lock seat is fixedly connected to the sliding support base, a support is fixedly connected to the base, and a lock block is rotatably connected to the support. The lock seat is provided with a lock groove that can cooperate with the lock block. The side of the lock groove away from the lock block has an arc-shaped structure, and the side of the lock groove close to the lock block has a vertical straight structure. When the plug assembly and the socket assembly are plugged in, the lock seat pushes the lock block to rotate. When the plug is fully engaged, the lock block and the lock groove cooperate to prevent the two from separating.

[0016] The technical solution of the present invention has at least the following advantages and beneficial effects: 1. The floating blind mating method for high-temperature, high-irradiation environments proposed in this invention effectively overcomes the radial misalignment problem caused by thermal deformation, material irradiation creep, installation platform vibration, or assembly deviation in traditional rigid mating assemblies under high-temperature, high-irradiation environments by achieving bidirectional floating of the plug or socket assembly in a plane perpendicular to the mating direction. This method allows for reliable alignment and smooth mating even with a certain radial offset between the plug and socket, significantly improving the environmental adaptability, operational fault tolerance, and connection reliability of the mating process. It fundamentally avoids risks such as pin damage, mating jamming, and connection failure caused by misalignment, making it suitable for long-term stable operation and maintenance under extreme conditions.

[0017] 2. In this invention, an adjustment mechanism is provided on each side of the support frame. Turning the adjustment screw can displace the adjustment plate. Since the adjustment sleeves in each elastic structure on the same side of the support frame are fixedly connected to the adjustment plate, the displacement of the adjustment plate can cause the adjustment sleeves in each elastic structure to move, thereby adjusting the preload of the springs in each elastic structure on the same side of the support frame. This method not only allows for direct external adjustment of the spring preload, but also prevents the adjustment sleeves from exerting preload on the springs when the plug assembly and socket assembly are separated for extended periods, avoiding stress relaxation caused by prolonged compression and improving the spring's service life.

[0018] 3. In this invention, when the plug assembly and the socket assembly are inserted, the locking seat on the sliding support pushes the locking block to rotate, causing the locking block to rotate into the locking groove on the locking seat. Since the side of the locking groove near the locking block is a vertical straight structure, the locking block and the locking groove can restrict the separation of the plug assembly and the socket assembly after they are engaged, thus preventing the drive mechanism from being unable to lock itself under strong vibration and causing the insertion to become loose. When the plug assembly and the socket assembly need to be separated, the locking block can be manually rotated out of the locking groove first, and then the plug assembly and the socket assembly can be separated by the drive mechanism.

Detailed Implementation

[0020] Example 1 A floating blind-mating method for high-temperature, high-irradiation environments allows the plug assembly 1 or socket assembly 2 to float in two mutually perpendicular directions within a plane perpendicular to the insertion / removal direction. Since the plug assembly 1 and socket assembly 2 engage and disengage along the pin axis, they can float in two directions within the radial plane of the pins to accommodate radial deviations between them. Furthermore, one of the plug assembly 1 and socket assembly 2 is fixed, while the other is driven by a drive mechanism to move along the insertion / removal direction. This drive mechanism enables the engagement or disengagement of the plug assembly 1 and socket assembly 2 without manual alignment (i.e., blind mating).

[0021] This invention effectively overcomes the radial misalignment problem caused by thermal deformation, material irradiation creep, installation platform vibration, or assembly deviation in traditional rigid connectors under high-temperature and high-irradiation environments by achieving bidirectional floating of the plug assembly 1 or socket assembly 2 in a plane perpendicular to the insertion / removal direction. This method enables reliable alignment and smooth insertion / removal even with a certain radial offset between the plug and socket through adaptive floating, significantly improving the environmental adaptability, operational fault tolerance, and connection reliability of the insertion process. It fundamentally avoids risks such as pin damage, insertion / removal jamming, and connection failure caused by misalignment, making it suitable for long-term stable operation and maintenance under extreme conditions.

[0022] In this embodiment, the float of the plug assembly 1 or the socket assembly 2 is ±5mm. If the two float directions are considered as the X and Y coordinate axes, and the initial state of either the plug assembly 1 or the socket assembly 2 is at the origin, then it is allowed to float 5mm in each of the positive and negative directions of the X and Y axes. It should be understood that in other embodiments, the float in the positive and negative directions of the X and Y axes can of course be greater than 5mm.

[0023] refer to Figures 1-3This invention also provides a floating blind-mating airtight connector assembly for high-temperature, high-irradiation environments. Employing the aforementioned floating blind-mating method, it includes a plug assembly 1, a socket assembly 2, and a base 5. One of the plug assembly 1 and the socket assembly 2 is fixedly connected to the base 5, while the other is slidably connected to the base 5 and connected to a driving mechanism. Alternatively, in this embodiment, the plug assembly 1 slides while the socket assembly 2 is fixed. Based on this, the driving mechanism is connected to the plug assembly 1, driving the plug assembly 1 closer to or further away from the socket assembly 2, thereby achieving insertion or separation. Specifically, the socket assembly 2 is disposed on a fixed support 3, and the plug assembly 1 is disposed on a sliding support 4, which is slidably connected to the base 5. It is readily understood that in other embodiments, the socket assembly 2 can also slide while the plug assembly 1 is fixed.

[0024] refer to Figures 3-7 The plug assembly 1 or the socket assembly 2 is provided with a floating support structure. As an option, in this embodiment, the floating support structure is provided on the plug assembly 1, that is, the plug assembly 1 can float bidirectionally in a plane perpendicular to the insertion and removal direction. It is easy to understand that in other embodiments, the floating support structure can also be provided on the socket assembly 2. The floating support structure includes a support frame 6, a floating mounting plate 7, and a floating support rod 10; the support frame 6 is connected to the base 5. It should be understood that when the floating support structure is provided on the plug assembly 1, the support frame 6 is connected to the sliding support seat 4, and the connection with the base 5 is achieved through the sliding support seat 4. The plug assembly 1 is fixed to the floating mounting plate 7. The support frame 6 has several limiting posts 8, which pass through floating holes on the floating mounting plate 7 and have retaining rings 9 at their ends. The diameter of the floating holes is larger than the diameter of the limiting posts 8. The limiting posts 8 and the floating holes work together to limit the maximum floating amount of the floating mounting plate 7. The retaining rings 9 limit the displacement of the floating mounting plate 7 in the insertion and removal direction. It is easy to understand that a small amount of displacement of the floating mounting plate 7 in the insertion and removal direction should be allowed to ensure that the floating mounting plate 7 can float in a plane perpendicular to the insertion and removal direction. The floating support rod 10 is connected to the support frame 6 around the perimeter through an elastic structure and abuts against the floating mounting plate 7. That is, the floating support rod 10 can elastically extend and retract, ensuring that the plug assembly 1 and the socket assembly 2 can float and plug in. After the plug assembly 1 and the socket assembly 2 are separated, the floating mounting plate 7 can also be reset under the action of the floating support rod 10 for easy insertion next time.

[0025] In this embodiment, one of the plug assembly 1 and the socket assembly 2 is provided with a mating guide post 101, and the other is provided with a mating guide sleeve 201 that mates with the mating guide post 101. The end of the mating guide sleeve 201 is provided with a tapered guide portion. It should be understood that during the mating process of the plug assembly 1 and the socket assembly 2, the mating guide post 101 first contacts the tapered guide portion at the end of the mating guide sleeve 201. The tapered guide portion can guide the two components (i.e., the plug assembly 1 and the socket assembly 2) to slide into the correct axial alignment even if there is a residual radial deviation, followed by the precise docking of the plug assembly 1 and the socket assembly 2. As an alternative, in this embodiment, the mating guide post 101 is provided on the plug assembly 1, and the mating guide sleeve 201 is provided on the socket assembly 2. In other embodiments, of course, the mating guide post 101 can be provided on the socket assembly 2, and the mating guide sleeve 201 can be provided on the plug assembly 1.

[0026] In this embodiment, the elastic structure includes a support sleeve 11, a threaded sleeve 12, and a spring 13. The support sleeve 11 is connected to the support frame 6 by screws and has one open end. The threaded sleeve 12 is threadedly connected to the open end of the support sleeve 11. The floating support rod 10 slides through the end of the threaded sleeve 12, and its inner end is provided with a stop that abuts against the end of the threaded sleeve 12. The stop prevents the floating support rod 10 from sliding out of the threaded sleeve 12, similar to the connection between a piston rod (and piston) and a piston cylinder. The spring 13 is located inside the threaded sleeve 12 and applies axial thrust to the floating support rod 10. That is, one end of the spring 13 abuts against the end face of the stop, and the other end abuts against the inner bottom of the support sleeve 11. Furthermore, it is worth noting that by threading the threaded sleeve 12 and the support sleeve 11, their relative axial positions can be adjusted, thereby adjusting the compression of the spring 13 and thus adjusting the magnitude of the restoring force applied to the floating mounting plate 7.

[0027] In this embodiment, the support frame 6 and the limiting post 8 are connected by a rivet (not shown) passing through the center of the limiting post 8, and the retaining ring 9 is limited by the rivet. In other embodiments, the limiting post 8 and the support frame 6 can be fixed in other ways, such as the limiting post 8 and the support frame 6 are connected by screws, and the limiting ring is connected to the limiting post 8 by threads or screws.

[0028] Refer again Figure 1In this embodiment, the drive mechanism includes a lead screw 14, a nut seat 16, and a knob 15. The nut seat 16 is located at the bottom of the sliding support 4 of the aforementioned connector assembly 1. The lead screw 14 is rotatably mounted on the top of the base 5. The nut seat 16 and the lead screw 14 are threaded together. The knob 15 is located at one end of the lead screw 14. In actual use, by rotating the knob 15 in both directions, the sliding support 4 can be moved back and forth, thereby realizing the insertion or separation of the connector assembly 1 and the socket assembly 2. In other embodiments, the drive mechanism can of course adopt other structures, such as a gear and rack mechanism, and the drive source can be manual or automatic (e.g., motor drive).

[0029] A limiting seat 17 is provided on the base 5 between the plug assembly 1 and the socket assembly 2. The limiting seat 17 can abut against the sliding support seat 4. That is, the limiting seat 17 restricts the final position of the plug assembly 1 when it is inserted. In other words, when the sliding support seat 4 abuts against the limiting seat 17, the insertion depth is determined, so that each insertion can reach the predetermined and optimal contact depth, ensuring the stability and reliability of electrical connection and airtight performance.

[0030] In this embodiment, the sliding support 4 and the base 5 are slidably connected as follows: guide rails 18 are provided on both sides of the top of the base 5, and a slider 19 that cooperates with the guide rails 18 is provided at the bottom of the sliding support 4. In other embodiments, the sliding support 4 and the base 5 can of course be slidably connected in other ways, such as by a guide rod cooperating with a linear bearing, that is, a guide rod is fixedly provided on the base 5, and a linear bearing that cooperates with the guide rod is provided on the sliding support 4.

[0031] The lubrication between the guide rail 18 and the slider 19, as well as between the lead screw 14 and the nut seat 16, uses nuclear-grade grease to improve lubrication stability under high radiation environments. It is easy to understand that other lubrication methods suitable for different environments can also be selected for use in other environments.

[0032] Furthermore, each component is selected from either metallic or non-metallic materials based on actual needs. Both metallic and non-metallic materials are made of high-temperature and radiation-resistant materials to ensure the environmental adaptability of the connector assembly under long-term operation in high-temperature and high-radiation conditions. Metallic materials can be passivated stainless steel, copper, etc.; non-metallic materials can be radiation-resistant low-phenyl silicone rubber (with good elasticity and radiation resistance), polyetheretherketone (PEEK) (with high temperature resistance and excellent mechanical strength), nitrile rubber and silicone rubber (for sealing structures in high-temperature and radiation environments), glass and ceramics (as inorganic non-metallic materials used for insulating components and supporting structures).

[0033] Example 2 The difference between this embodiment and Embodiment 1 lies in the specific structure of the elastic structure. In this embodiment, the elastic structure includes a guide inner sleeve 20, an adjusting outer sleeve 21, and a spring 13. The adjusting outer sleeve 21 slides through the outside of the support frame 6 with its inner end open. The guide inner sleeve 20 slides through the inside of the open end of the adjusting outer sleeve 21. The floating support rod 10 slides through the end of the threaded sleeve 12, and its inner end is provided with a stop that abuts against the end of the guide inner sleeve 20. The spring 13 is located inside the guide inner sleeve 20 and applies axial thrust to the floating support rod 10. That is, one end of the spring 13 abuts against the end face of the stop, and the other end abuts against the inner bottom of the adjusting outer sleeve 21. It should be understood that when the adjusting outer sleeve 21 is axially displaced, the preload of the spring 13 changes accordingly.

[0034] Based on the above, each side of the support frame 6 is provided with an adjustment mechanism. The adjustment mechanism includes a fixed plate 23, a guide rod 24, an adjustment plate 25, and an adjustment screw 26. In this embodiment, there are two guide rods 24 (in other embodiments, it can be designed to have more than two). One end of the guide rod 24 is fixedly connected to the support frame 6, and the fixed plate 23 is fixedly connected to the other end of the guide rod 24. The adjustment plate 25 is slidably connected to the guide rod 24. Each adjustment sleeve 21 on the same side of the support frame 6 is fixedly connected to the adjustment plate 25 (so that when the adjustment plate 25 moves, each adjustment sleeve 21 on the same side moves simultaneously). The adjustment screw 26 is rotatably connected between the fixed plate 23 and the support frame 6, and the adjustment screw 26 and the adjustment plate 25 are connected by a thread.

[0035] In practical applications, turning the adjusting screw 26 can move the adjusting plate 25. Since the adjusting sleeves 21 in each elastic structure on the same side of the support frame 6 are fixedly connected to the adjusting plate 25, the displacement of the adjusting plate 25 can move the adjusting sleeves 21 in each elastic structure, thereby adjusting the preload of the springs 13 in each elastic structure on the same side of the support frame 6. This method not only allows for direct external adjustment of the preload of the springs 13, but also prevents the adjusting sleeves 21 from exerting a preload on the springs 13 when the plug assembly 1 and the socket assembly 2 are separated for a long period of time. This avoids stress relaxation caused by long-term compression of the springs 13 and improves the service life of the springs 13.

[0036] Example 3 The difference between this embodiment and embodiment 1 is that, in this embodiment, the limiting seat 17 is not provided, but a locking seat 27 is fixedly connected to the sliding support seat 4, a support 29 is fixedly connected to the base 5, and a locking block 28 is rotatably connected to the support 29. The locking seat 27 is provided with a locking groove that can cooperate with the locking block 28. The side of the locking groove away from the locking block 28 has an arc-shaped structure, and the side of the locking groove close to the locking block 28 has a vertical straight structure. It should be understood that the locking block 28 also has an arc-shaped structure on one side and a vertical straight structure on the other side.

[0037] When the plug assembly 1 and the socket assembly 2 are inserted, the locking seat 27 on the sliding support 4 pushes the locking block 28 to rotate, causing the locking block 28 to rotate into the locking groove on the locking seat 27. Since the side of the locking groove near the locking block 28 is a vertical straight structure, the locking block 28, after engaging with the locking groove, can restrict the separation of the plug assembly 1 and the socket assembly 2, preventing the drive mechanism from failing to self-lock under strong vibration and causing loosening of the connection. When the plug assembly 1 and the socket assembly 2 need to be separated, the locking block 28 is manually rotated out of the locking groove first (even if the locking block 28 faces...). Figure 10 By rotating clockwise, the plug assembly 1 can be separated from the socket assembly 2 via the drive mechanism.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
