[0002] A power adapter is a device that converts one type of plug to another, widely used for interchangeable plug standards between different countries or regions, such as USB charging plugs, computer power plugs, and power plugs from various countries. With increasing demands for electrical safety, smart power adapters also utilize technologies such as built-in AC / DC converter modules to achieve power status monitoring and remote control, thus better protecting electrical equipment.

[0003] Different countries and regions have different plug standards. For example, although German standard (Schuko, Type F) and French standard (Type E) plugs look similar, their grounding structures and internal socket structures differ significantly. To meet the needs of different countries, manufacturers usually need to develop dedicated adapters for each standard. However, the development of new products involves mold development, structural design, testing, and certification, which are costly and time-consuming.

[0004] In view of this, the purpose of the present invention is to provide a new technical solution to solve the existing technical problems. Summary of the Invention

[0021] The following is in conjunction with the appendix Figure 1-11 The present invention will be further described below.

[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0023] Reference Figures 1 to 11 This invention provides an intelligent converter, which includes a German-style module 400 or a French-style module 700. The German-style module 400 includes a German-style grounding component 4 and a universal module 100; the French-style module 700 includes a French-style grounding component 7 and the universal module 100. That is, the universal module 100 is a module common to both the German-style module 400 and the French-style module 700. The universal module 100 can be selectively combined with either the German-style grounding component 4 or the French-style grounding component 7 to form either a German-style intelligent converter or a French-style intelligent converter, respectively.

[0024] By setting up a universal module 100 shared by both German and French smart converters, manufacturers only need to develop a mold for the universal module 100, and then develop the outer shell, inner shell and grounding spring for German and French models respectively, thus producing two products, significantly reducing the total cost of molds and parts management costs.

[0025] Reference Figures 1 to 5 The general module 100 includes a circuit board assembly 1 and live / neutral wire pins 2, which are electrically connected to the circuit board assembly 1. Specifically, the live / neutral wire pins 2 are two standard metal pins, which are electrically connected to the live and neutral wires on the circuit board assembly 1, respectively. The circuit board assembly 1 includes a circuit board 11 and a pin spring 12, which is fixedly mounted on the circuit board 11. Specifically, the pin spring 12 has solder feet 121, and a groove 122 is formed at the bottom end of the solder feet 121. The pin spring 12 is soldered to the circuit board 11 through the solder feet 121. By forming a groove 122 at the bottom end of the solder feet 121, the contact area of ​​the soldering area is increased, thereby enhancing the solder adhesion and improving the solder joint strength.

[0026] Reference Figure 3 Furthermore, the pin spring 12 is provided with a spring-back notch 123 on the side facing the circuit board 11. By providing the spring-back notch 123, sufficient spring-back space is provided between the soldered pin spring 12 and the circuit board 11 to avoid the solder solidification causing the pin spring 12 to lose its elasticity.

[0027] Furthermore, the pin spring 12 has an outwardly extending spring 124 on the side facing the plug. When the plug is inserted into the pin spring 12, the extending spring 124 contacts the plug pins. By providing the extending spring 124, the contact area with the plug pins is increased, thereby reducing the contact resistance.

[0028] Reference Figure 2 Furthermore, a support post 112 is fixedly provided on the circuit board 11. The support post 112 is located between the live and neutral wire pins and the plug spring 12 to increase the support strength and reduce the possibility of the circuit board 11 deforming when the plug is inserted.

[0029] Furthermore, the circuit board 11 has a clearance through hole 111 for accommodating the grounding pin 72 when assembling the French smart converter, while the clearance through hole 111 can be left unused in the German converter.

[0030] Reference Figure 4 The general module 100 also includes a safety door assembly 3, which includes a pressure plate 31 and an elastic element.

[0031] Reference Figures 2 to 8 The German-style module 400 includes a German-style outer shell 5, a German-style inner shell 6, a universal module 100, and a German-style grounding component 4. The German-style intelligent converter is assembled from the components of the German-style module 400. The German-style inner shell 6 is detachably disposed within the German-style outer shell 5, and a German-style mounting cavity is formed between the German-style inner shell 6 and the German-style outer shell 5. The universal module 100 is disposed within the German-style mounting cavity, and the German-style inner shell 6 secures and restricts the universal module 100 within the German-style mounting cavity.

[0032] Furthermore, refer to Figure 6 and Figure 7 The German-style grounding assembly 4 includes a German-style grounding spring 41, which includes a mounting portion 411 and a spring arm 412. A grounding through hole is provided on the mounting portion 411, and a plug sleeve 413 is fixedly mounted on one end face of the mounting portion 411, corresponding to the position of the grounding through hole. The spring arm 412 is integrally formed on both ends of the mounting portion 411 and extends towards the plug sleeve 413. A contact spring 415 is provided at the end of the spring arm 412 away from the mounting portion 411. The contact spring 415 has a "C"-shaped structure, and the contact springs 415 on the two elastic arms are mirror-shaped. The contact spring 415 is designed as a "C"-shaped reinforcing structure to increase the rigidity of the contact end of the German-style grounding spring 41.

[0033] The German-style outer casing 5 has a German-style pin through-hole 53 on the end face away from the German-style inner casing 6, through which the neutral and live wire pins 2 pass. When the universal module 100 is installed in the German-style mounting cavity, the two metal pins of the neutral and live wire pins 2 protrude from the pin through-hole. The end face of the German-style inner casing 6 has a German-style socket 61, which corresponds to the position of the pin spring 12. The plug of the electrical equipment can be inserted into the German-style mounting cavity through the German-style socket 61 and electrically connected to the pin spring 12.

[0034] Reference Figure 6 and Figure 7 The German-style outer casing 5 has a mounting groove 411 for accommodating the mounting part 411 of the German-style grounding spring 41, and a socket groove 54 for accommodating the plug socket 413 on its end face away from the German-style inner casing 6. The socket groove 54 is connected to the mounting groove. The inner wall of the German-style outer casing 5 has a mounting slot 51 for accommodating the spring arm 412 of the German-style grounding spring 41. When the mounting part 411 is installed in the mounting groove, the spring arm 412 is inserted into the mounting slot 51. A one-way spring buckle 4121 is integrally formed on the spring arm 412. A limiting step 52 is provided on the inner wall of the German-style outer casing 5. When the spring arm 412 is inserted into the mounting slot 51 and installed in place, the one-way spring buckle 4121 abuts against the limiting step 52, forming a one-way snap-fit, which can only be inserted and cannot be removed. At this time, the German-style grounding spring 41 and the German-style outer casing 5 are limited and fixed, ensuring the reliability of the assembly.

[0035] Furthermore, a spring shoulder 414 is provided at the connection between the contact spring 415 and the spring arm 412. A slot 62 corresponding to the position of the contact spring 415 is provided on the German-style inner shell 6. When the German-style ground spring 41 is installed in place, the contact spring 415 passes through the slot 62, and the spring shoulder 414 abuts against the edge of the end face of the slot 62 to support the contact spring 415. This changes the fulcrum position of the contact spring 415, thereby reducing the lever arm of the German-style ground spring 41. This allows the contact spring 415 to still generate a large clamping force even when the German-style ground spring 41 is made of thin copper sheet, ensuring reliable contact with the grounding spring of the German plug.

[0036] In this embodiment, the German-style grounding spring 41 is a one-piece stamped metal part made of thin copper sheet.

[0037] Reference Figures 4 to 6 The safety door assembly 3 is used to close the German-style socket 61, wherein the pressure plate 31 is rotatably mounted, and the elastic member is used to keep the pressure plate 31 closed in the German-style socket 61. In this embodiment, a fixing member 33 for limiting the position of the pressure plate 31 is also provided.

[0038] Furthermore, the pressure plate 31 has a two-bladed paddle-shaped structure, allowing it to rotate in a plane parallel to the German-style inner shell 6. Specifically, a rotating shaft is located in the center of the side of the German-style inner shell 6 facing the German-style mounting cavity, and a rotating hole is opened in the center of the pressure plate 31. The rotating hole cooperates with the rotating shaft, allowing the pressure plate 31 to rotate horizontally around the rotating shaft. The fixing member 33 is connected to the German-style inner shell 6, and the pressure plate 31 is positioned between the German-style inner shell 6 and the fixing member 33. The fixing member 33 limits the pressure plate 31 to prevent it from detaching from the German-style inner shell 6.

[0039] Furthermore, the portion of the pressure plate 31 facing the German-style socket 61 is designed as an inclined surface 311, meaning both blades of the pressure plate 31 have inclined surfaces 311. When an external force is applied to the inclined surfaces 311, they guide the movement of the pressure plate 31, causing it to rotate around the axis. The elastic element is a spring 32, with one end connected to one side of the blades of the pressure plate 31 and the other end connected to the German-style inner shell 6. When the electrical equipment plug is not inserted, the pressure plate 31 is pushed by the spring 32 to close the German-style socket 61, meaning the two blades of the pressure plate 31 are directly above the two pin springs 12, blocking the German-style socket 61. When the electrical equipment plug is inserted into the German-style socket 61, the pressure plate 31 is pressed by the metal pins of the plug. Guided by the inclined surfaces 311, the pressure plate 31 rotates horizontally and presses the spring 32, opening the German-style socket 61.

[0040] Safety door assembly 3 is provided. When the metal prongs of the electrical device plug are inserted into the German-style socket 61, the elastic element is squeezed or stretched to open the pressure plate 31 and connect the circuit. When the metal prongs of the plug are pulled out of the socket, the pressure plate 31 returns to its original position with the elastic element and re-closes the German-style socket 61, preventing people or animals from accidentally touching the electrical socket and causing danger. The pressure plate 31 rotates parallel to the plane of the German-style inner shell 6, which saves more internal space of the German-style outer shell 5 compared to the top-and-bottom flip-up structure.

[0041] Reference Figure 8 The German-style inner shell 6 is detachably installed inside the German-style outer shell 5. Specifically, the inner wall of the German-style outer shell 5 is provided with a shell tenon 55, and the outer wall of the German-style inner shell 6 is provided with an inner shell tenon 64. The shell tenon 55 and the inner shell tenon 64 correspond one-to-one to form a mortise and tenon structure. The inner wall of the German-style outer shell 5 is provided with a shell tenon 56, and the outer wall of the German-style inner shell 6 is provided with an inner shell tenon 63. The shell tenon 56 and the inner shell tenon 63 correspond one-to-one to form a mortise and tenon structure. The German-style inner shell 6 and the German-style outer shell 5 are installed and fixed through the mortise and tenon structure, which is simple in structure and has high assembly efficiency.

[0042] Reference Figure 5Furthermore, the general module 100 also includes a switch 13. In the German-style module 400, the switch 13 is located on the side of the German-style housing 5 and is connected in series with the pin spring 12. When the electrical equipment is not used for a long time, to protect the safety of the electrical equipment, the power supply to the equipment can be disconnected by turning off the switch 13 on the German-style housing 5 without unplugging the plug.

[0043] Reference Figure 2 and Figure 10 The French module 700 includes a French outer shell 8, a French inner shell 9, a universal module 100, and a French grounding component 7. The French smart converter is assembled from the components of the French module 700. The French inner shell 9 is detachably housed within the French outer shell 8, forming a French mounting cavity between them. The universal module 100 is housed within this cavity, and the French inner shell 9 secures and restricts the universal module 100 within it. The connection structure between the French inner shell 9 and the French outer shell 8 is similar to the connection structure between the German inner shell 6 and the German outer shell 5. The universal module 100 is identical to that used in the German module 400, meaning the circuit board assembly 1, live and neutral wire pins 2, safety door assembly 3, and switch 13 are the same set of components. It can share production lines and molds with the German module 400, and will not be described further here.

[0044] Reference Figures 9 to 11 The French grounding assembly 7 includes a French grounding spring 71 and a grounding pin 72. The French grounding spring 71 includes a horizontal portion 711, a plug arm 712, and a riveting arm 713. A French socket 714 is provided on one end face of the horizontal portion 711. The plug arm 712 is located at both ends of the horizontal portion 711 and extends towards the French socket 714. The riveting arm 713 is connected and fixed to the horizontal portion 711 and extends along one side of the French socket 714, with the riveting arm 713 located on one side of the French socket 714. A riveting hole 7131 is provided at the end of the riveting arm 713 away from the horizontal portion 711, and the grounding pin 72 is riveted and fixed to the riveting hole 7131. During assembly, the grounding pin 72 passes through the clearance through hole 111 on the circuit board 11.

[0045] A French grounding spring 71 is inserted into the French housing 8. Specifically, the end face of the French housing 8 away from the French inner housing 9 has a horizontal recess 711 for accommodating the French grounding spring 71, and a riveting recess 84 for accommodating the French insert 714 and the riveting arm 713. The horizontal recess and the riveting recess 84 are connected. The bottom of the riveting recess 84 has a recessed through hole for the grounding pin 72 to pass through. The inner wall of the French housing 8 has a French slot 81 for accommodating the insert arm 712 of the French grounding spring 71. When the horizontal part 711 is installed in the horizontal recess, the insert arm 712 is inserted into the French slot 81, the riveting arm 713 and the French insert 714 are installed in the riveting recess 84, and the grounding pin 72 passes through the recessed through hole. The plug arm 712 has an integrally formed plug spring 7121, and the inner wall of the French housing 8 is provided with a snap-fit ​​step 82. When the plug arm 712 is inserted into the French slot 81 and installed in place, the French spring abuts against the snap-fit ​​step 82 to form a one-way snap-fit, which can only be inserted and cannot be removed. At this time, the French ground wire spring 71 and the French housing 8 are limited and fixed to ensure the reliability of the assembly.

[0046] In this embodiment, the French grounding spring 71 is a one-piece stamped metal part made of thin copper sheet.

[0047] The French-style outer shell 8 has a French-style pin through-hole 83 on the end face away from the French-style inner shell 9, through which the neutral and live wire pins 2 pass. When the universal module 100 is installed in the French-style mounting cavity, the two metal pins of the neutral and live wire pins 2 extend out from the French-style pin through-hole 83. The end face of the French-style inner shell 9 has a French-style socket 91, which corresponds to the position of the pin spring 12. The end face of the French-style inner shell 9 also has a pin through-hole 92 for the grounding pin 72 to pass through. When the French-style grounding assembly 7 is installed on the French-style outer shell 8, the grounding pin 72 extends out from the pin through-hole 92. The plug of the electrical equipment can be inserted into the French-style mounting cavity through the French-style socket 91 and electrically connected to the pin spring 12. The grounding pin 72 can be grounded with the plug of the electrical equipment.

[0048] During assembly, the general module 100 is first installed into the French housing 8, and then the French inner housing 9 is covered. Then, the French grounding spring 71 with the grounding pin 72 already riveted is inserted from the end face of the French housing 8, so that the grounding pin 72 passes through the recessed through hole on the French housing 8, the clearance through hole 111 on the circuit board 11, and the pin through hole 92 on the French inner housing 9 in sequence.

[0049] It should be noted that the intelligent converter of the present invention also includes structures commonly used in intelligent converters, such as AC / DC converter modules. The specific structural forms and implementation principles are based on existing technologies and will not be elaborated here.

[0050] The intelligent converter of this invention uses the same universal module 100 for both the German-style module 400 and the French-style module 700. During production, the universal module 100 can be mass-produced and then assembled with components specific to either the German-style intelligent converter (German-style outer shell 5, German-style inner shell 6, German-style grounding component 4) or the French-style intelligent converter (French-style outer shell 8, French-style inner shell 9, French-style grounding component 7) according to order requirements, forming the finished German-style or French-style intelligent converter. Since only one mold for the universal module 100 needs to be developed, and the dedicated components for the German and French styles are independent but relatively simple in structure, the overall mold cost is significantly reduced compared to developing two separate complete products. Furthermore, the standardized production of the universal module 100 helps improve production efficiency and quality management.
