Abstract
Description
Technical Field
[0001] This utility model relates to the field of power switching equipment technology, and in particular to an automatic power switching device for redundant power supplies of hot-swappable modules. Background Technology
[0002] In the field of electronic equipment, hot-swappable modules are being used more and more widely, especially in scenarios such as servers and industrial control equipment. To ensure the continuous and stable operation of the equipment, redundant power supply designs are often used.
[0003] However, existing hot-swappable power switching devices are prone to generating static electricity during the plugging and unplugging process, which affects the performance and lifespan of the power module and equipment; in addition, the power connection structure is not stable enough and there are cases of poor contact, which may cause momentary power outages during switching, reducing the reliability of equipment operation.
[0004] In addition, the existing switching devices have poor fault tolerance for plugging and unplugging operations, and even a slight deviation in operation may cause malfunctions.
[0005] Therefore, this utility model proposes an automatic power switching device for redundant power supplies of hot-swappable modules. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic power switching device for redundant power supplies of hot-swappable modules.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automatic power switching device for redundant power supplies of a hot-swappable module, including a socket assembly, the socket assembly being composed of a socket cover, and further comprising:
[0008] The plug assembly consists of a plug socket and a plug block disposed on one side of the socket cover. The plug socket is connected to the socket cover via the plug block. Both ends of the plug block are provided with sliding holes. A trigger rod is disposed inside the plug socket and passes through the plug socket. A connecting plate is disposed at one end of the trigger rod inside the plug socket. There are two connecting plates in total, and a rectangular frame is disposed between the two connecting plates. A conductive post is disposed at one end of the rectangular frame near the plug block.
[0009] Furthermore, a total of four conductive posts are provided, and the four conductive posts are respectively located at the four corners of the rectangular frame. A static elimination plate is provided at one end of the plug block near the plug socket, and the static elimination plate is in contact with the conductive posts.
[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: When the device is working, during the insertion of the plug assembly, the static elimination plate contacts the conductive post, which can quickly neutralize the static electricity generated by plugging and unplugging, and avoid static electricity interference with the operation of the power module and damage to equipment components. The four conductive posts distributed at the corners of the rectangular frame increase the contact area of the power connection and evenly distribute the force. Combined with the guiding design of the plug block, the connection between the plug and the socket is more stable, reducing loosening and poor contact, ensuring smooth and uninterrupted power transmission, and improving the reliability and stability of the entire redundant power automatic switching device.
[0011] Furthermore, an insulating spring is provided at one end of the trigger rod located inside the plug socket, and the two ends of the insulating spring are in contact with the plug socket and the connecting plate, respectively.
[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: the two ends of the insulating spring at the inner end of the trigger rod are in contact with the plug socket and the connecting plate, respectively. When the plug assembly is inserted, the trigger rod is pressed, which drives the connecting plate to compress the spring, so that the conductive structure is connected and the power is switched. When pulled out, the spring releases its elastic force to push the trigger rod to reset and disconnect the power connection. This design utilizes the elastic reset characteristics of the spring to ensure that the trigger rod can automatically complete the triggering and resetting actions during the insertion and removal process. At the same time, the insulating spring isolates the circuit to avoid the risk of leakage, making the power switching operation smoother and improving the safety and stability of the device.
[0013] Furthermore, each socket cover has a socket component plug socket inside. There are two socket component plug sockets, and the two socket component plug sockets are symmetrical about the center of the socket cover. Each socket component plug socket is provided with a pressing slider, and the pressing slider is provided with a sliding buckle that is slidably connected to the socket component plug socket. The pressing slider is in contact with the trigger rod.
[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: Two plug sockets are symmetrically arranged inside the socket cover. The pressing sliders on them are slidably connected by a sliding buckle and contact the trigger rod. When the plug assembly is inserted, the slider is pressed and slides along the sliding buckle, pushing the trigger rod and triggering the power switching. When the plug is pulled out, the slider returns to its original position. The symmetrical structure makes the plug evenly stressed and the insertion more stable. The sliding cooperation between the slider and the sliding buckle ensures accurate triggering action, making the power switching process smooth and reliable. The dual plug socket design can also realize the automatic switching of redundant power supplies, improving the stability and reliability of the device.
[0015] Furthermore, a fault-tolerant sleeve is provided between the extrusion slider and the socket cover, and the fault-tolerant sleeve is made of rubber.
[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the rubber fault-tolerant sleeve between the extrusion slider and the socket cover utilizes the elastic deformation characteristics of rubber to buffer and offset the lateral force during the insertion process when the insertion angle of the plug assembly is slightly deviated, avoiding the slider jamming or trigger rod deformation due to operation errors. Its fault-tolerant design can adapt to a certain range of insertion and removal offsets, reduce the installation accuracy requirements, make the insertion and removal operation smoother, reduce component wear, improve the device's tolerance to operation errors, and enhance the overall structural reliability and service life.
[0017] Furthermore, a second connecting wire is provided on one side of the socket cover, and a first connecting wire is provided on one side of the plug socket.
[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: the second connecting line on one side of the socket cover and the first connecting line on the other side of the plug socket are respectively used for connecting the external main power supply, the backup power supply and the hot-swappable module. After the two are connected by structures such as conductive posts, the power path can be automatically switched during plugging and unplugging, so that the main and backup power supplies are connected through the second connecting line and then supply stable power to the module through the first connecting line. This wiring design clearly divides the power input and output paths, ensures stable power signal transmission, makes the redundant power switching process more reliable, and ensures the continuity and safety of the equipment power supply.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0020] In this invention, the plug socket of the plug assembly is connected to the socket cover via a plug block with a sliding hole. The sliding hole provides guidance for insertion, allowing the plug block to move smoothly along a predetermined path. When inserted, the plug block pushes the trigger rod, which in turn drives the connecting plate and the rectangular frame, causing the conductive post to contact the conductive structure inside the socket, thus achieving power connection. When pulled out, the trigger rod resets under the action of a spring, disconnecting the connection. This structure converts the insertion and removal action into the linear motion of the trigger rod. The rectangular frame ensures that multiple conductive posts move synchronously, achieving fast and stable power switching. At the same time, the sliding hole guide design reduces insertion resistance, improving operational smoothness and connection reliability. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figure 1-5 As shown, this utility model provides a technical solution: an automatic power switching device for redundant power supplies of a hot-swappable module, including a socket assembly 2, which is composed of a socket cover 21, and further including:
[0031] The plug assembly 1 consists of a plug socket 11 and a plug block 13 disposed on one side of the socket cover 21. The plug socket 11 is connected to the socket cover 21 via the plug block 13. Both ends of the plug block 13 have sliding holes 131. A trigger rod 15 is disposed inside the plug socket 11, penetrating the plug socket 11. A connecting plate 17 is disposed at one end of the trigger rod 15 inside the plug socket 11. Two connecting plates 17 are disposed, and a rectangular frame 14 is disposed between the two connecting plates 17. A conductive post 141 is disposed at the end of the rectangular frame 14 near the plug block 13. The plug socket 11 of the plug assembly 1 connects to the plug block 13 with the plug socket 11 via the sliding holes 131. The socket cover 21 is connected, and the sliding hole 131 provides a guide for insertion, allowing the plug block 13 to move smoothly along a predetermined path. When inserted, the plug block 13 pushes the trigger rod 15, which drives the connecting plate 17 and the rectangular frame 14, so that the conductive post 141 contacts the conductive structure inside the socket, realizing power connection. When pulled out, the trigger rod 15 resets under the action of the spring and disconnects the connection. This structure converts the insertion and removal action into the linear movement of the trigger rod 15. The rectangular frame 14 ensures that multiple conductive posts 141 move synchronously, realizing fast and stable power switching. At the same time, the guiding design of the sliding hole 131 reduces insertion resistance and improves the smoothness of operation and connection reliability.
[0032] Four conductive posts 141 are provided, and the four conductive posts 141 are respectively located at the four corners of the rectangular frame 14. A static elimination plate 18 is provided at the end of the plug block 13 near the plug socket 11. The static elimination plate 18 and the conductive posts 141 are in contact with each other. When the device is working, during the insertion of the plug assembly 1, the static elimination plate 18 and the conductive posts 141 are in contact, which can quickly neutralize the static electricity generated by plugging and unplugging, and avoid static electricity interference with the operation of the power module and damage to equipment components. The four conductive posts 141 distributed at the corners of the rectangular frame 14 increase the contact area of the power connection and evenly distribute the force. Combined with the guiding design of the plug block 13, the connection between the plug and the socket is more stable, reducing loosening and poor contact, ensuring smooth and uninterrupted power transmission, and improving the reliability and stability of the entire redundant power automatic switching device.
[0033] An insulating spring 16 is provided at one end of the trigger rod 15 located inside the plug socket 11. The two ends of the insulating spring 16 are in contact with the plug socket 11 and the connecting plate 17, respectively. When the plug assembly 1 is inserted, the trigger rod 15 is pressed, which causes the connecting plate 17 to compress the spring, so that the conductive structure is connected and the power is switched. When it is pulled out, the spring releases its elastic force and pushes the trigger rod 15 to reset, disconnecting the power connection. This design utilizes the elastic reset characteristic of the spring to ensure that the trigger rod 15 can automatically complete the triggering and resetting actions during insertion and removal. At the same time, the insulating spring 16 isolates the circuit to avoid the risk of leakage, making the power switching operation smoother and improving the safety and stability of the device.
[0034] The socket cover 21 has two socket components 2 plug sockets 11 inside, and the two socket components 2 plug sockets 11 are symmetrical about the center of the socket cover 21. The socket component 2 plug socket 11 is provided with a pressing slider 23, and the pressing slider 23 is provided with a sliding buckle 231 that is slidably connected to the socket component 2 plug socket 11. The pressing slider 23 contacts the trigger rod 15. The two plug sockets 11 are symmetrically arranged inside the socket cover 21, and the pressing slider 23 on them is slidably connected to the trigger rod 15 through the sliding buckle 231. When the plug component 1 is inserted, the slider is pressed and slides along the sliding buckle 231 and pushes the trigger rod 15, triggering the power switching. When it is pulled out, the slider returns to its original position. The symmetrical structure makes the plug evenly stressed and the insertion more stable. The sliding cooperation between the slider and the sliding buckle 231 ensures accurate triggering action and makes the power switching process smooth and reliable. The dual plug socket 11 design can also realize the automatic switching of redundant power supplies, improving the stability and reliability of the device.
[0035] A fault-tolerant sleeve 24 is provided between the extrusion slider 23 and the socket cover 21. The fault-tolerant sleeve 24 is made of rubber. The rubber fault-tolerant sleeve 24 between the extrusion slider 23 and the socket cover 21 utilizes the elastic deformation characteristics of rubber to buffer and offset the lateral force during the insertion process when the insertion angle of the plug assembly 1 is slightly deviated. This prevents the slider from getting stuck or the trigger rod 15 from deforming due to operation errors. Its fault-tolerant design can adapt to a certain range of insertion and removal offsets, reduce the installation accuracy requirements, make the insertion and removal operation smoother, reduce component wear, improve the device's tolerance to operation errors, and enhance the overall structural reliability and service life.
[0036] A second connecting line 22 is provided on one side of the socket cover 21, and a first connecting line 12 is provided on one side of the plug socket 11. The second connecting line 22 on one side of the socket cover 21 and the first connecting line 12 on the side of the plug socket 11 are respectively used to connect the main power supply, the backup power supply, and the hot-swappable module. After the two are connected by structures such as the conductive post 141, the power path can be automatically switched when plugging and unplugging, so that the main and backup power supplies are connected through the second connecting line 22, and then the module is stably powered through the first connecting line 12. This wiring design clearly divides the power input and output paths, ensures stable power signal transmission, makes the redundant power switching process more reliable, and ensures the continuity and safety of the equipment power supply.
