Description
Technical Field
[0001] The present application relates to the technical field of power supply, and particularly to a power connection device. Background Art
[0002] In the use and debugging of electronic devices such as servers, a power supply unit (PSU) is connected to a socket through a 220V power cord for power supply. However, there are many problems with traditional 220V PSU power cords and sockets. Its plug is designed with three cores (live wire, neutral wire, and ground wire). Although it has an anti-misinsertion function, it is difficult to align the plug with the socket holes, and it is easy to damage the device or cause accidents due to poor contact. When the plug is not fully inserted, some metal pins are exposed outside without insulation treatment, which is easy to cause electric shock. Although the safety shielding piece set inside the socket can improve safety, it requires greater force when plugging and unplugging, and is easy to wear. After increasing the number of uses, problems such as stuck holes and poor contact may occur. In the research and development and debugging of electronic products, frequent plugging and unplugging of the power cord can easily fatigue the debugging personnel and there is a risk of loose connection.
[0003] Therefore, there is an urgent need for a power connection device that can improve convenience, safety, and reliability during the connection process between the plug and the socket to meet the actual use requirements. Summary of the Invention

[0006] Wherein, the vertical distance of the anti-electric shock module on the socket base surface is greater than the vertical distance of the conductive pin group on the socket base surface;
[0007] During the process of the first guiding module and the second guiding module being cooperatively connected, the power supply pin group approaches the conductive pin group in a preset moving direction until power conduction is achieved between the socket and the plug.

[0013] In one embodiment, the diameters of the ground-line power supply pin ring, the zero-line power supply pin ring and the live-line power supply pin ring decrease in sequence.
[0014] In one embodiment, the first radius difference between the ground-line power supply pin ring and the zero-line power supply pin ring is less than a preset value, and the second radius difference between the zero-line power supply pin ring and the live-line power supply pin ring is less than the preset value.

[0030] Referring to Figure 1 , Figure 1 FIG. 1 shows a schematic diagram of a socket 1 that meets the mains standard in the prior art; the socket 1 is designed to receive a standard three-core power plug 2, including a live wire, a neutral wire and a ground wire. The live wire and the neutral wire are responsible for providing power and a return circuit respectively, while the ground wire is used for safety grounding to prevent electric shock caused by electric leakage when an electrical device fails. Figure 1 In FIG. 1, the upper part of the socket 1 is a ground wire jack, the left side is a neutral wire jack, and the right side is a live wire jack. This layout complies with the safety standards in most regions and ensures the safety of users during use. However, as mentioned above, this traditional three-core plug 2 design has some inconveniences in actual use, such as difficult insertion and removal, poor contact and other problems, which may affect the stability and safety of the device.
[0031] To solve the above technical problems, Figure 2 FIG. 2 shows an overall schematic diagram of a power connection device in an embodiment of the present application. The device includes a socket 1 and a plug 2. The socket 1 includes a socket base surface 11, and an electric shock prevention module 12, a first guiding module 13 and a conductive pin group 14 disposed on the socket base surface 11; one end of the plug 2 is connected to the mains, and the other end includes a power supply pin group 21 and a second guiding module 22, and the power supply pin group 21 and the second guiding module 22 are fixedly connected; wherein, the vertical distance of the electric shock prevention module 12 on the socket base surface 11 is greater than the vertical distance of the conductive pin group 14 on the socket base surface 11; during the process of the first guiding module 13 and the second guiding module 22 being cooperatively connected, the power supply pin group 21 approaches the conductive pin group 14 in a preset moving direction until power conduction is achieved between the socket 1 and the plug 2.
[0032] Specifically, the socket 1 includes a socket base surface 11, an electric shock prevention module 12, a first guiding module 13 and a conductive pin group 14; wherein:
[0033] The socket base surface 11 is the main part of the socket 1, providing an installation foundation; the electric shock prevention module 12 is located on the socket base surface 11, aiming to prevent users from accidentally contacting the live parts when plugging and unplugging the power cord, thus avoiding electric shock accidents; the vertical distance of the electric shock prevention module 12 on the socket base surface 11 is greater than the vertical distance of the conductive pin group 14 on the socket base surface 11, indicating that when the plug 2 is not fully inserted, the conductive pin group 14 will not be exposed, thus increasing safety.
[0034] The first guiding module 13 is located between the electric shock prevention module 12 and the conductive pin group 14, and is used to guide the correct insertion of the plug 2 into the socket 1. It helps ensure that the power supply pin group 21 can be accurately aligned and connected to the conductive pin group 14.
[0035] The conductive pin group 14 is responsible for establishing an electrical connection with the power supply pin group 21 of the plug 2 to achieve power transmission.
[0036] The plug 2 includes a power supply pin group 21 and a second guiding module 22, where:
[0037] One end of the power supply pin group 21 connected to the mains is responsible for transmitting electricity from the mains to the device. The power supply pin group 21 is fixedly connected to the second guiding module 22 to ensure correct alignment during insertion.
[0038] The second guiding module 22 cooperates with the first guiding module 13 to ensure that the power supply pin group 21 can approach and connect to the conductive pin group 14 along a preset moving direction. This design helps simplify the plugging and unplugging process and reduces poor contact or damage caused by improper alignment.
[0039] The working principle is as follows: When the plug 2 is inserted into the socket 1, the second guiding module 22 interacts with the first guiding module 13 to guide the power supply pin group 21 to approach the conductive pin group 14 along a preset moving direction. During the insertion process, the electric shock prevention module 12 ensures that users will not contact the live parts before the power supply pin group 21 is fully aligned with the conductive pin group 14, thus improving safety. Once the power supply pin group 21 is correctly docked with the conductive pin group 14, the power is conducted between the socket 1 and the plug 2, and the device starts to receive power.
[0040] In the embodiment of the present application, by controlling the vertical distance between the electric shock prevention module 12 and the conductive pin group 14, it is further ensured that only when the plug 2 is fully inserted, the power supply pin group 21 can contact the conductive pin group 14, thus ensuring the correct connection of the circuit. This design not only improves the reliability of the power connection but also adapts to various application scenarios, bringing a safer and more convenient power connection experience to users.
[0041] In an exemplary embodiment, the electric shock prevention module 12 is disposed around the side of the conductive pin group 14, and the first guiding module 13 is disposed on one side of the electric shock prevention module 12 close to the power supply pin group 21.
[0042] Specifically, the following different structural forms are listed:
[0043] 1. The electric shock prevention module 12 can be designed into a structure that surrounds the conductive pin group 14, similar to an annular or semi-annular shield, completely surrounding the side of the conductive pin group 14. The first guiding module 13 can be designed into a shape that closely cooperates with the electric shock prevention module 12, such as a wedge shape or an inclined plane, to guide the smooth insertion of the power supply pin group 21.
[0044] 2. The electric shock prevention module 12 can be designed into a slidable structure. When the plug 2 is inserted, the electric shock prevention module 12 slides along the guide rail, exposing the conductive pin group 14. The first guiding module 13 can be integrated with the sliding electric shock prevention module 12 to ensure that the power supply pin group 21 can be accurately aligned with the conductive pin group 14 during the sliding process.
[0045] 3. The electric shock prevention module 12 can be designed into a foldable structure. When the plug 2 is inserted, the electric shock prevention module 12 folds to one side, exposing the conductive pin group 14. The first guiding module 13 can be designed to cooperate with the folding mechanism to ensure that the power supply pin group 21 can be smoothly aligned with the conductive pin group 14 during the folding process.
[0046] 4. The electric shock prevention module 12 can be designed into a telescopic structure. When the plug 2 is inserted, the electric shock prevention module 12 retracts backward, exposing the conductive pin group 14. The first guiding module 13 can be integrated with the telescopic mechanism to ensure that the power supply pin group 21 can be accurately aligned with the conductive pin group 14 during the telescopic process.
[0047] In this embodiment, the above-listed structural forms are all aimed at improving the safety and convenience of use of the socket 1 through a physical barrier and a guiding mechanism. Through different mechanical designs, a balance between safety and convenience during the insertion and extraction of the plug 2 can be achieved.
[0048] In an exemplary embodiment, the first guiding module 13 includes a guiding ring groove, the guiding ring groove is opened on the side wall of the electric shock prevention module 12 close to the conductive pin group 14, and the central axis of the guiding ring groove is perpendicular to the socket base surface 11; the second guiding module 22 includes a guiding block adapted to the shape of the guiding ring groove; wherein, the cross-sectional area of the guiding ring groove on the side away from the power supply pin group 21 is larger than the cross-sectional area on the side close to the power supply pin group 21.
[0049] It should be noted that the first guiding module 13 may further include a first smooth member (such as a slide rail or a smooth layer) disposed in the guiding ring groove for reducing the moving friction; the second guiding module 22 further includes a second smooth member (such as a slide rail or a smooth layer) disposed on the guiding block.
[0050] Specifically, the guiding ring groove is a structure opened on the side wall of the electric shock prevention module 12. It can be a circular ring groove or a ring groove of any polygon, and is located on the side of the electric shock prevention module 12 close to the conductive pin group 14. The central axis of this ring groove is perpendicular to the socket base surface 11, indicating that it extends along the normal direction of the socket base surface 11. The design of the guiding ring groove is to cooperate with the guiding block of the second guiding module 22 to ensure that the plug 2 can move in the correct direction when inserted into the socket 1.
[0051] The guiding block of the second guiding module 22 is a structure on the plug 2, and its shape is adapted to the guiding ring groove of the first guiding module 13, so that the guiding block can be smoothly inserted into the guiding ring groove. The function of the guiding block is to guide the power supply pin group 21 to approach the conductive pin group 14 along a preset moving direction until the power is turned on.
[0052] The cross-sectional area of the guiding ring groove on the side away from the power supply pin group 21 is larger than that on the side close to the power supply pin group 21. The purpose is to provide a certain guiding force during the insertion process of the plug 2 to help the power supply pin group 21 more stably align with the conductive pin group 14. The larger cross-sectional area can provide a better guiding effect to ensure that the plug 2 will not deviate from the correct direction during the insertion process.
[0053] As Figure 2 and Figure 3 shown, the structures of the PSU power socket 1 and the plug 2 are shown. One end of the plug 2 is connected to the mains power, and the other end includes a power supply pin group 21 and a second guiding module 22. The first guiding module 13 is disposed on the side of the electric shock prevention module 12 close to the power supply pin group 21, and the guiding ring groove thereon cooperates with the guiding block of the second guiding module 22 to ensure that the power supply pin group 21 can move in the correct direction. When the power plug 2 is inserted into the socket 1, the guiding block of the second guiding module 22 moves along the guiding ring groove of the first guiding module 13 to guide the power supply pin group 21 to approach the conductive pin group 14 until the power is turned on.
[0054] In this embodiment, through the cooperation of the guiding ring groove and the guiding block, the accuracy and stability of the insertion of the plug 2 are improved, and the safety during use is also enhanced.
[0055] In an exemplary embodiment, the cross-section of the guiding ring groove is circular, and at least one circle of guiding threads is provided on two adjacent side walls of the guiding ring groove and the guiding block close to each other. The rotational displacement direction of the guiding threads is the preset moving direction.
[0056] Specifically, the cooperation between the guiding ring groove and the guiding block can be achieved in the following ways:
[0057] Method 1: Unidirectional spiral guiding thread structure: The cross-section of the guiding ring groove is circular, and a unidirectional spiral guiding thread is provided on its inner wall. A unidirectional spiral guiding thread matching the thread on the inner wall of the guiding ring groove is also provided on the corresponding side of the guiding block.
[0058] Working principle: When the power plug 2 is inserted into the socket 1, the thread on the guiding block meshes with the thread in the guiding ring groove. Due to the unidirectional design of the thread, the power supply pin group 21 can only move along the preset moving direction (for example, clockwise or counterclockwise along the direction perpendicular to the base surface 11 of the socket), so as to ensure correct alignment and connection.
[0059] Method 2: Bidirectional spiral guiding thread structure: Bidirectional spiral guiding threads are provided on both the guiding ring groove and the guiding block, that is, the thread can rotate in two directions.
[0060] Working principle: During the insertion process, the bidirectional spiral guiding thread ensures that the power supply pin group 21 moves along the preset moving direction. During the extraction process, the other direction of the thread can provide stable guiding to prevent the plug 2 from falling off accidentally.
[0061] Method 3: Multi-turn guiding thread structure: Multi-turn guiding threads are provided on both the guiding ring groove and the guiding block, and the pitch and angle of each turn of the thread may be different to adapt to different insertion depths and guiding requirements.
[0062] Working principle: The multi-turn thread design can provide more precise control during the insertion process to ensure that the power supply pin group 21 can be correctly aligned with the conductive pin group 14 at different stages. This design can also provide additional stability and control when pulling out the plug 2.
[0063] Method 4: Adjustable guiding thread structure: The guiding threads on the guiding ring groove and the guiding block can be adjustable, for example, the tightness or rotation direction of the thread can be changed through an external adjustment mechanism.
[0064] Working principle: This design allows the guiding thread to be adjusted according to different types of plugs 2 and sockets 1 to adapt to different application requirements. The adjustable thread can provide greater flexibility during installation or maintenance.
[0065] Method 5: Composite guiding thread structure: The guiding threads on the guiding ring groove and the guiding block can be composite, that is, different thread types (such as unidirectional and bidirectional threads) are combined on the same thread.
[0066] Working principle: The composite thread can provide different guiding and locking functions during the insertion and extraction processes, ensuring that the power supply pin group 21 moves in the correct direction and can stably maintain its position after connection.
[0067] In this embodiment, the cooperation between the guiding ring groove and the guiding block is realized through a guiding thread. This design can provide precise guiding and positioning, ensuring that the power supply pin group 21 can smoothly approach the conductive pin group 14 along the preset moving direction.
[0068] In an exemplary embodiment, the power supply pin group 21 includes a neutral wire power supply pin ring, a live wire power supply pin ring, and a ground wire power supply pin ring with the same central axis but different radii; the conductive pin group 14 includes a neutral wire conductive pin ring, a live wire conductive pin ring, and a ground wire conductive pin ring with the same central axis but different radii; wherein, the neutral wire conductive pin ring is used to contact the neutral wire power supply pin ring, the live wire conductive pin ring is used to contact the live wire power supply pin ring, and the ground wire conductive pin ring is used to contact the ground wire power supply pin ring.
[0069] Specifically, the power supply pin group 21 includes three pin rings with the same central axis but different radii, namely the neutral wire power supply pin ring, the live wire power supply pin ring, and the ground wire power supply pin ring. The same central axis of these pin rings means that they are all arranged around the same center point, but their radii are different, which helps to distinguish and correctly align during insertion.
[0070] The conductive pin group 14 also includes three pin rings with the same central axis but different radii, namely the neutral wire conductive pin ring, the live wire conductive pin ring, and the ground wire conductive pin ring. These conductive pin rings are also arranged around the same center point but have different radii to ensure correct contact with the corresponding pin rings in the power supply pin group 21.
[0071] In this embodiment, the neutral wire conductive pin ring is used to contact the neutral wire power supply pin ring, the live wire conductive pin ring is used to contact the live wire power supply pin ring, and the ground wire conductive pin ring is used to contact the ground wire power supply pin ring. This design ensures that when the plug 2 is inserted into the socket 1, each line (neutral wire, live wire, and ground wire) can be correctly and stably connected, thereby providing the required power for the device. By ensuring independent contact points for the neutral wire, live wire, and ground wire, this design helps to improve the safety of the electrical system and prevent short circuits or electrical faults. In addition, the design with different radii helps to reduce misoperations during the plugging and unplugging processes and improve the reliability of the connection.
[0072] In practical applications, this design can be used for various devices that require a stable power connection, such as household appliances, industrial equipment, or electronic devices. By ensuring the correct connection of the neutral wire, live wire, and ground wire, this design helps to improve the operating stability and safety of the device.
[0073] In an exemplary embodiment, the conductive regions of the neutral power supply pin ring, the live power supply pin ring, and the ground power supply pin ring are all located on the outer sidewall of the corresponding pin ring; the conductive regions of the neutral conductive pin ring, the live conductive pin ring, and the ground conductive pin ring are all located on the inner sidewall of the corresponding pin ring.
[0074] Specifically, the conductive region of the neutral power supply pin ring is located on the outer sidewall of the pin ring, and the conductive region of the neutral conductive pin ring is located on the inner sidewall of the pin ring. When the plug 2 is inserted into the socket 1, the outer sidewall of the neutral power supply pin ring will contact the inner sidewall of the neutral conductive pin ring; the conductive region of the live power supply pin ring is located on the outer sidewall of the pin ring, and the conductive region of the live conductive pin ring is located on the inner sidewall of the pin ring, ensuring that the outer sidewall of the live power supply pin ring will contact the inner sidewall of the live conductive pin ring; the conductive region of the ground power supply pin ring is also located on the outer sidewall of the pin ring, and the conductive region of the ground conductive pin ring is located on the inner sidewall of the pin ring, making the outer sidewall of the ground power supply pin ring contact the inner sidewall of the ground conductive pin ring.
[0075] In this embodiment, the design of the conductive regions on the outer and inner sidewalls enables each line (neutral, live, and ground) to be stably connected, thereby providing the required power for the device. By ensuring independent contact points for the neutral, live, and ground lines, this design helps improve the safety of the electrical system and prevent short circuits or electrical failures. In addition, the design of the conductive regions on different sidewalls helps reduce misoperations during plugging and unplugging processes and improves the reliability of the connection. The design of the conductive regions on the outer and inner sidewalls can also provide additional structural stability to ensure that the pin rings will not be easily deformed or damaged during the connection process.
[0076] In an exemplary embodiment, the diameters of the ground power supply pin ring, the neutral power supply pin ring, and the live power supply pin ring decrease in sequence.
[0077] Specifically, ground connection is prioritized: The ground wire is usually used for safety grounding and has the largest diameter, which means that when the plug 2 is inserted into the socket 1, the ground power supply pin ring will contact the ground conductive pin ring first, thus establishing the ground connection first. This helps ensure that the device housing is grounded before the device is powered on, reducing the risk of electric shock. The live power supply pin ring has the smallest diameter, which means that when the plug 2 is unplugged from the socket 1, the live power supply pin ring will be disconnected last. This can ensure that the device has been disconnected from the power supply before the plug 2 is unplugged, further reducing the risk of electric shock.
[0078] In this embodiment, since the diameters of the pin rings decrease in sequence, the plug 2 can be more easily aligned when inserted into the socket 1. The larger pin ring first makes contact and guides the plug 2 into the correct position, while the smaller pin rings ensure a secure final connection. This design can also reduce the likelihood of insertion errors. Due to the different sizes of the pin rings, users can visually identify each pin ring during insertion, thereby reducing the probability of incorrect insertion. The design of pin rings with different diameters can also enhance the stability of the connection. The larger pin rings can provide more stable physical support, while the smaller pin rings can ensure the tightness of the electrical connection.
[0079] In an exemplary embodiment, the first radius difference between the ground wire power supply pin ring and the neutral wire power supply pin ring is less than a preset value, and the second radius difference between the neutral wire power supply pin ring and the live wire power supply pin ring is less than a preset value.
[0080] Specifically, the first radius difference refers to the radius difference between the ground wire power supply pin ring and the neutral wire power supply pin ring. This difference is controlled below a preset value to ensure that the two pin rings can be smoothly separated during insertion, avoiding insertion difficulties or poor contact caused by overly small sizes. The second radius difference refers to the radius difference between the neutral wire power supply pin ring and the live wire power supply pin ring. Similarly, this difference is also controlled below a preset value to ensure that the neutral wire and live wire pin rings can be correctly aligned and make contact during insertion.
[0081] In an exemplary embodiment, the preset value is 1 millimeter.
[0082] Specifically, when the preset value is 1 millimeter (or other safety distances suitable for users), and the design requirement is to ensure that fingers cannot touch the conductive area, this means that when designing the power plug 2 and the socket 1, it is necessary to ensure that there is at least a 1 - millimeter distance between any conductive part (such as the power supply pin ring and the conductive pin ring) and the surface of the socket 1 or the plug 2 housing. Such a design is mainly for safety considerations, aiming to prevent users from accidentally touching the live part during normal use or plugging and unplugging the plug 2, thereby avoiding electric shock accidents. The following is a specific understanding of this design:
[0083] In this embodiment, the 1 - millimeter safety distance is a minimum value, ensuring that even under manufacturing tolerances or wear, users' fingers will not touch any live conductive area. By maintaining at least a 1 - millimeter distance, the risk of accidental electric shock can be reduced.
[0084] In an exemplary embodiment, the materials of both the first guiding module 13 and the second guiding module 22 are insulating materials.
[0085] Specifically, the guiding module is usually located near the connection area of the power plug 2 and the socket 1. If these components use conductive materials, they may accidentally come into contact with the conductive parts of the power supply, resulting in a short circuit. Using insulating materials can prevent such accidental contact, thus avoiding short circuits and other related electrical problems. Insulating materials usually have good chemical resistance and temperature resistance, which means that even under harsh environmental conditions, the guiding module can maintain its performance and will not degrade due to environmental factors. This durability helps to improve the reliability of the power connection.
[0086] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this application.
[0087] The above-described embodiments merely represent several implementation manners of this application. The description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of this application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application shall be subject to the appended claims.
