Description

[Technical Field]

[0001] The present invention relates to the technical field of power converters, and more particularly to a compact power converter pin combination structure. [Background technology]

[0002] Plugs and sockets are not universal because standards vary from country to country. If you need to plug into a socket with a different standard, you need to use a power converter. A power converter is an adapter tool. To use it, insert the power converter into the target socket, and then insert the target plug into the corresponding socket hole on the power converter to perform the conversion. The advent of power converters has made people's lives more convenient, especially when traveling across borders. There is no need to worry about problems caused by the plug of an electronic device not fitting into the local socket.

[0003] In conventional power converters, the pins are generally fixed and extended. In the case of a power converter with multiple pins, the multiple pins must be individually installed to avoid mutual influence between the pins. However, such an individually installed method makes the overall size of the power converter too large, which makes it inconvenient to carry when traveling and affects the user experience. Summary of the Invention [Problem to be solved by the invention]

[0004] In response to the above drawbacks, the objective of the present invention is to provide a compact pin combination structure for a power converter, which reduces the overall length and volume of the power converter by overlapping the spaces occupied by the American standard pin unit, the European standard pin unit, and the British standard pin unit, making it more convenient to carry when traveling.

DETAILED DESCRIPTION OF THE INVENTION

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose, specific embodiments of the present invention will be described in detail below with reference to the drawings and preferred examples.

[0029] In addition, in the description of this invention, the orientations or positional relationships indicated by terms such as "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," and "outside" are orientations or positional relationships based on the drawings, and are intended to facilitate and simplify the description of this invention. They do not indicate or imply that the indicated devices or elements must have a specific orientation, or be configured or operate in a specific orientation, and therefore do not limit this invention.

[0030] Furthermore, the terms "first" and "second" are for descriptive purposes only and cannot be understood to denote or imply relative importance or the number of technical features depicted. Thus, a feature qualified by "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "plurality" means two or more, unless otherwise expressly specified.

[0031] In the present invention, unless otherwise expressly defined and limited, the terms "attach," "couple," "connect," "fixed," etc. should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or an integral connection. They may also refer to a mechanical connection or an electrical connection. They may also refer to a direct connection, an indirect connection via an intermediate medium, an internal communication between two elements, or an interactive relationship between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art depending on the circumstances.

[0032] Example 1 1 to 12, an embodiment of the present invention provides a compact power converter pin assembly structure, which includes an American standard pin unit 1 installed in the power converter and a British standard pin unit 2 installed in the power converter, the British standard pin unit 2 including a British standard shared slide base 21 slidably installed in the power converter and a British standard ground wire pin 22 installed in the British standard shared slide base 21, the British standard shared slide base 21 having an overall U-shape and a retreat space 211 formed therein, the American standard pin unit 1 including an American standard shared slide base 11 installed in the power converter and slidably installed in the retreat space 211, the American standard shared slide base 11 having a British standard ground wire retreat slot 111 recessed inward to fit the British standard ground wire pin 22, the British standard ground wire pin 22 moving along the British standard ground wire retreat slot 111. As the American standard pin unit 1 slides within the retraction space 211, the space occupied by the American standard pin unit 1 and the space occupied by the British standard pin unit 2 overlap, and the British standard grounding wire pin 22 moves linearly along the British standard grounding wire retraction slot 111, thereby further saving the space occupied by the British standard grounding wire pin 22 and the American standard pin unit 1, reducing the overall length and volume of the power converter, making it more convenient to carry when traveling.

[0033] Preferably, to further improve the practicality of the power converter, as shown in FIGS. 2-3 , 5 , 6 , and 8 , the power converter pin assembly structure of the present invention further includes a European pin unit 3 installed within the power converter and sliding within the retraction space 211. The European pin unit 3 includes a European common sliding base 31 installed within the power converter and sliding within the retraction space 211, one European hot pin 32 installed within the European common sliding base 31, and one European neutral pin 33 installed within the European common sliding base 31. The installation of the European pin unit 3 within the power converter further improves the selectability of pins that can be used, improving the practicality of the power converter and facilitating use during travel. When the European pin unit 3 needs to be used, simply push the European common sliding base 31 out of the power converter, and push the European hot pin 32 and the European neutral pin 33 out of the power converter to achieve European pin conversion. When the European standard pin unit 3 moves within the evacuation space 211, the space occupied by the European standard pin unit 3, the space occupied by the US standard pin unit 1, and the space occupied by the British standard pin unit 2 overlap, reducing the overall length and volume of the power converter, making it more convenient to carry when traveling.

[0034] Regarding the specific form of the electrical connection between the European standard pin unit 3 and the power converter, as shown in Figures 2 to 3, 5, 6 and 8, the European standard pin unit 3 further includes a European standard live conductor piece 34 mounted on the European standard shared slide base 31, extending outward and electrically connected to the European standard live pin 32, and a European standard neutral conductor piece 35 mounted on the European standard shared slide base 31, extending outward and electrically connected to the European standard neutral pin 33. When the European standard live pin 32 and the European standard neutral pin 33 are pushed out by the European standard shared slide base 31, the European standard live conductor piece 34 and the European standard neutral conductor piece 35 provided in the European standard shared slide base 31 move synchronously therewith, and the European standard live conductor piece 34 and the European standard neutral conductor piece 35 are inserted into the conductive mechanism in the power converter, thereby realizing an electrical connection through conduction between the European standard pin unit 3 and the power converter. This process ensures stable conduction and improves conduction efficiency.

[0035] 2 to 3, 5, 6 and 8, to further save space within the power converter and facilitate pushing out the European-standard pin unit 3 for use, the British standard shared slide base 21 is formed with a European-standard conductor retraction slot 212 recessed at an end away from the retraction space 211, through which the European-standard live conductor 34 and the European standard neutral conductor 35 move when linearly driven by the European standard shared slide base 31. The European standard live conductor 34 and the European standard neutral conductor 35 move up and down within the European standard conductor retraction slot 212, so that the space occupied by the European standard live conductor 34 and the European standard neutral conductor 35 overlaps with the space occupied by the British standard shared slide base 21. This further saves space within the power converter, reduces the overall length and volume of the power converter, makes it more convenient to carry when traveling, and facilitates pushing out the European-standard pin unit 3 for use.

[0036] Regarding other configurations of the British Standard pin unit 2, as shown in Figure 6, the British Standard earth wire pin 22 is provided at one end of the U-shaped structure of the British Standard shared slide base 21, and the British Standard pin unit 2 further includes a British Standard neutral wire pin 24 provided on one side of the other end of the U-shaped structure of the British Standard shared slide base 21, and a British Standard live wire pin 23 provided on the other side of the other end of the U-shaped structure of the British Standard shared slide base 21.

[0037] Regarding other configurations of the American standard pin unit 1, as shown in FIG. 7, the American standard pin unit 1 further includes an American standard live pin 12 mounted on the American standard shared slide base 11 and an American standard neutral pin 13 mounted on the American standard shared slide base 11, and the American standard live pin 12 and the American standard neutral pin 13 are located on both sides of the British standard grounding pin 22, so that the spaces occupied by the American standard pin unit 1 and the British standard pin unit 2 overlap, reducing the overall length and volume of the power converter, and making it more convenient to carry when traveling.

[0038] As for the specific form for pushing out the British Standard pin unit 2 from the power converter, as shown in FIG. 6, the British Standard shared slide base 21 is provided with a British Standard pin lever 213 that extends outside the power converter, and the user can simply press the British Standard pin lever 213 to push out the British Standard shared slide base 21 and structures such as the British Standard live line pin 23, British Standard neutral line pin 24, and British Standard earth line pin 22 provided on the British Standard shared slide base 21 from the power converter, making it simple and easy to use.

[0039] As for the specific form for pushing out the US standard pin unit 1 from the power converter, as shown in FIG. 7, the US standard shared slide base 11 is provided with a US standard pin lever 112 that extends outside the power converter, and the user can simply press the US standard pin lever 112 to push out the US standard shared slide base 11 and structures such as the US standard live line pin 12 and US standard neutral line pin 13 provided on the US standard shared slide base 11 from the power converter, making it simple and easy to use.

[0040] As for the specific method for pushing out the European standard pin unit 3 from the power converter, as shown in FIG. 8, the European standard shared slide base 31 is provided with a European standard pin lever 311 that extends outside the power converter. By simply pressing the European standard pin lever 311, the user can push out the European standard shared slide base 31 and structures such as the European standard live line pin 32 and the European standard neutral line pin 33 provided on the European standard shared slide base 31 from the power converter, making it simple and easy to use.

[0041] In order to allow users to select different pin units more accurately, the British standard pin lever 213, the American standard pin lever 112, and the European standard pin lever 311 are arranged alternately, as shown in Figures 1 and 2. The staggered configuration allows users to easily use different pin units and effectively prevents multiple levers from being pressed unintentionally.

[0042] Preferably, as shown in Figures 1 and 2, the initial height of the European standard pin lever 311 is greater than the initial height of the British standard pin lever 213 and the initial height of the American standard pin lever 112. This provides a staggered configuration, which can effectively prevent multiple levers from being pressed unintentionally.

[0043] Regarding the electrical connection configuration within the power converter, as shown in Figures 2 and 9-10, the power converter pin assembly structure of the present invention further includes a socket hot conductor clip 4 and a socket neutral conductor clip 5 provided within the power converter. When the British standard pin unit 2 is used in an extruded state, the British standard hot conductor tab provided on the British standard shared slide base 21 is inserted into the socket hot conductor clip 4, and the British standard neutral conductor tab provided on the British standard shared slide base 21 is inserted into the socket neutral conductor clip 5, thereby achieving a conductive connection between the British standard pin unit 2 and the power converter. When the American standard pin unit 1 is used in an extruded state, the American standard hot conductor tab provided on the American standard shared slide base 11 is inserted into the socket hot conductor clip 4, and the American standard neutral conductor tab provided on the American standard shared slide base 11 is inserted into the socket neutral conductor clip 5, thereby achieving a conductive connection between the American standard pin unit 1 and the power converter. When the European standard pin unit 3 is pushed out for use, the European standard live conductor piece 34 provided on the European standard shared slide base 31 is inserted into the socket live conductor clip 4, and the European standard neutral conductor piece 35 provided on the European standard shared slide base 31 is inserted into the socket neutral conductor clip 5, thereby realizing a conductive connection between the European standard pin unit 3 and the power converter.

[0044] In order to further save space inside the power converter, as shown in FIGS. 2 and 9 to 10, the socket live wire conductive clip 4 is bent upward in a "U" shape to form a European standard live wire conductive retraction slot 41 for retracting the European standard pin unit 3, and the socket neutral wire conductive clip 5 is bent upward in a "U" shape to form a European standard neutral wire conductive retraction slot 51 for retracting the European standard pin unit 3. By providing the European standard live wire conductive retraction slot 41 for retracting the European standard pin unit 3 in the socket live wire conductive clip 4, different pin units are connected in the socket live wire conductive clip 4, and the space occupied by it overlaps with the European standard pin unit 3, so that the overall length of the power converter becomes smaller, the overall volume of the power converter becomes smaller, and it is more convenient to carry during travel. By providing the European standard neutral wire conductive retraction slot 51 for retracting the European standard pin unit 3 in the socket neutral wire conductive clip 5, different pin units are connected in the socket neutral wire conductive clip 5, and the space occupied by it overlaps with the European standard pin unit 3, so that the overall length of the power converter becomes smaller, the overall volume of the power converter becomes smaller, and it is more convenient to carry during travel.

[0045] 9 to 12, the socket live wire conductive clip 4 further includes live wire conductive clips 42, which are provided at both ends of the European standard live wire conductive recess 41 and into which the external plug is inserted. The live wire conductive clips 42 may include live wire clamps suitable for various plug models, such as a British standard live wire clamp suitable for the British standard live wire pins of the external plug, a US standard live wire clamp suitable for the US standard live wire pins of the external plug, an Australian standard or Chinese standard live wire clamp suitable for the Australian standard or Chinese standard live wire pins of the external plug, or a European standard live wire clamp suitable for the European standard pins of the external plug, thereby meeting various plug conversion needs and facilitating use during travel. The staggered arrangement of the various live wire clamps effectively reduces the overall space occupied by the power converter, effectively reducing the overall volume and making it more convenient to carry when traveling.

[0046] 9 to 12, the socket neutral conductor clip 5 includes neutral conductor conductive clips 52 disposed at both ends of the European standard neutral conductor conductive recessing slot 51 for receiving an external plug. The socket neutral conductor clip 5 further includes neutral conductor conductive clips 52 disposed at both ends of the European standard neutral conductor recessing slot 51 for receiving an external plug. The neutral conductor conductive clips 52 may include neutral conductor clamps suitable for neutral conductors of various plug models, such as a British standard neutral conductor clamp for fitting the British standard neutral conductor pin of an external plug, an American standard neutral conductor clamp for fitting the American standard neutral conductor pin of an external plug, an Australian standard or Chinese standard neutral conductor clamp for fitting the Australian standard or Chinese standard neutral conductor pin of an external plug, or a European standard neutral conductor clamp for fitting the European standard pin of an external plug, thereby meeting the needs of various plug conversions and facilitating use during travel. By arranging various neutral wire clamping portions alternately, the overall space occupied is effectively reduced, the overall volume of the power converter is effectively reduced, and it is more convenient to carry when traveling.

[0047] As for other configurations of the socket live wire conductive clip 4 and the socket neutral wire conductive clip 5, their specific structures and operating modes are conventional technologies in the relevant field, and therefore are not particularly limited in this embodiment and may be installed according to actual conditions.

[0048] In order to improve the safety of the power converter, as shown in Figures 2 and 10 to 12, the power converter pin combination structure of the present invention further includes a safety device 6 installed in the power converter, which is connected to the conductive structure in the power converter to protect the circuit of the power converter and effectively improve the safety of the power converter.

[0049] In order to further save space within the power converter, as shown in Figures 3 to 6 and 12, the British Standard shared slide base 21 is recessed into the evacuation space 211 and has a British Standard fuse evacuation section 214 for evacuating the safety device 6. This allows the space occupied by the safety device 6 and the space occupied by the British Standard pin unit 2 to overlap, further saving space within the power converter, reducing the overall length and volume of the power converter, making it more convenient to carry when traveling.

[0050] Preferably, as shown in Figures 3 to 6 and 12, the British Standard fuse retraction portion 214 is inclined, which provides more space for retracting the safety device 6 and makes it easier to install and use the safety device 6.

[0051] Regarding the specific configuration of the safety device 6, the safety device 6 may be a fuse tube, a fuse wire, a fusing device, etc., and may be installed according to the actual situation, and is not particularly limited in this embodiment.

[0052] Example 2 As shown in Figures 13 to 24, the power converter pin combination structure of the present invention includes an American standard pin unit 1 and a British standard pin unit 2 installed in the power converter, the British standard pin unit 2 includes a British standard shared slide base 21 slidably installed in the power converter and a British standard ground wire pin 22 installed in the British standard shared slide base 21, the British standard shared slide base 21 is generally U-shaped and has an evacuation space 211 formed therein, the British standard ground wire pin 22 is located outside the evacuation space 211, the American standard pin unit 1 includes an American standard shared slide base 11 installed outside the evacuation space 211, the American standard shared slide base 11 has a British standard ground wire evacuation slot 111 recessed inward to fit the British standard ground wire pin 22, and the British standard ground wire pin 22 is configured to move along the British standard ground wire evacuation slot 111. The American standard pin unit 1 slides out of the retraction space 211, and the British standard grounding pin 22 moves along the British standard grounding retraction slot 111. This allows the space occupied by the American standard pin unit 1 and the space occupied by the British standard pin unit 2 to partially overlap, thereby reducing the overall length and volume of the power converter and making it more convenient to carry when traveling. Other internal structures of the power converter may also be provided in the retraction space 211, thereby further saving space within the power converter.

[0053] Preferably, to further improve the practicality of the power converter, as shown in Figures 13 to 24, the power converter pin assembly structure of the present invention further includes a European pin unit 3 installed within the power converter and sliding within the retraction space 211. The European pin unit 3 includes a European shared sliding base 31 installed within the power converter and linearly moving within the retraction space 211, one European live pin 32 installed on the European shared sliding base 31, and one European neutral pin 33 installed on the European shared sliding base 31. The installation of the European pin unit 3 within the power converter further improves the selectability of pins that can be used, improving the practicality of the power converter and facilitating use during travel. When the European pin unit 3 needs to be used, simply push the European shared sliding base 31 out of the power converter, and push the European live pin 32 and the European neutral pin 33 out of the power converter to achieve European pin conversion. When the European standard pin unit 3 moves within the evacuation space 211, the space occupied by the European standard pin unit 3, the space occupied by the US standard pin unit 1, and the space occupied by the British standard pin unit 2 overlap, reducing the overall length and volume of the power converter, making it more convenient to carry when traveling.

[0054] Regarding the specific form of the electrical connection between the European standard pin unit 3 and the power converter, as shown in FIG. 20 , the European standard pin unit 3 further includes a European standard live conductor piece 34 mounted on the European standard shared slide base 31, extending outward and electrically connected to the European standard live pin 32, and a European standard neutral conductor piece 35 mounted on the European standard shared slide base 31, extending outward and electrically connected to the European standard neutral pin 33. When the European standard live pin 32 and the European standard neutral pin 33 are pushed out by the European standard shared slide base 31, the European standard live conductor 34 and the European standard neutral conductor 35 provided in the European standard shared slide base 31 move synchronously therewith, and then the European standard live conductor 34 and the European standard neutral conductor 35 are inserted into the conductive mechanism in the power converter, thereby realizing an electrical connection through conduction between the European standard pin unit 3 and the power converter. This process ensures stable conduction and improves conduction efficiency.

[0055] Preferably, as shown in Figures 15 to 16, 18 and 20, in order to further save space within the power converter and make it easier to push out the European-standard pin unit 3 for use, the British standard shared slide base 21 is formed with a European-standard conductor retraction slot 212 recessed at an end away from the retraction space 211, through which the European-standard live conductor 34 and the European standard neutral conductor 35 move when linearly driven by the European standard shared slide base 31. The European standard live conductor 34 and the European standard neutral conductor 35 move up and down within the European standard conductor retraction slot 212, so that the space occupied by the European standard live conductor 34 and the European standard neutral conductor 35 overlaps with the space occupied by the British standard shared slide base 21. This further saves space within the power converter, reduces the overall length and volume of the power converter, makes it more convenient to carry when traveling, and makes it easier to push out the European-standard pin unit 3 for use.

[0056] Regarding other configurations of the British Standard pin unit 2, as shown in FIG. 18, the British Standard earth wire pin 22 is provided at one end of the U-shaped structure of the British Standard shared slide base 21, and the British Standard pin unit 2 further includes a British Standard neutral wire pin 24 provided on one side of the other end of the U-shaped structure of the British Standard shared slide base 21, and a British Standard live wire pin 23 provided on the other side of the other end of the U-shaped structure of the British Standard shared slide base 21.

[0057] Regarding other configurations of the American standard pin unit 1, as shown in FIG. 19, the American standard pin unit 1 further includes an American standard live line pin 12 mounted on the American standard shared slide base 11 and an American standard neutral line pin 13 mounted on the American standard shared slide base 11, and the American standard live line pin 12 and the American standard neutral line pin 13 are located on both sides of the British standard ground line pin 22, so that the spaces occupied by the American standard pin unit 1 and the British standard pin unit 2 overlap, reducing the overall length and volume of the power converter, and making it more convenient to carry when traveling.

[0058] As for the specific form for pushing out the British Standard pin unit 2 from the power converter, as shown in FIG. 18, the British Standard shared slide base 21 is provided with a British Standard pin lever 213 that extends outside the power converter, and the user can simply press the British Standard pin lever 213 to push out the British Standard shared slide base 21 and structures such as the British Standard live line pin 23, British Standard neutral line pin 24, and British Standard earth line pin 22 provided on the British Standard shared slide base 21 from the power converter, making it simple and easy to use.

[0059] As for the specific form for pushing out the US standard pin unit 1 from the power converter, as shown in Figure 19, the US standard shared slide base 11 is provided with a US standard pin lever 112 that extends outside the power converter, and the user can simply press the US standard pin lever 112 to push out the US standard shared slide base 11 and structures such as the US standard live line pin 12 and US standard neutral line pin 13 provided on the US standard shared slide base 11 from the power converter, making it simple and easy to use.

[0060] As for the specific method for pushing out the European standard pin unit 3 from the power converter, as shown in FIG. 20, the European standard shared slide base 31 is provided with a European standard pin lever 311 that extends outside the power converter, and the user can simply press the European standard pin lever 311 to push out the European standard shared slide base 31 and structures such as the European standard live line pin 32 and European standard neutral line pin 33 provided on the European standard shared slide base 31 from the power converter, making it easy and convenient to use.

[0061] In order to allow users to select different pin units more accurately, the British standard pin lever 213, the American standard pin lever 112, and the European standard pin lever 311 are arranged in a staggered manner, as shown in Figure 13. The staggered arrangement allows users to easily use different pin units and effectively prevents multiple levers from being pressed unintentionally.

[0062] Preferably, as shown in Figure 13, the initial height of the European standard pin lever 311 is greater than the initial height of the British standard pin lever 213 and the initial height of the American standard pin lever 112. This provides a staggered configuration, which effectively prevents multiple levers from being pressed unintentionally.

[0063] Regarding the electrical connection configuration within the power converter, as shown in Figures 14, 21 and 22, the power converter pin assembly structure of the present invention further includes a socket hot conductor clip 4 and a socket neutral conductor clip 5 provided within the power converter. When the British standard pin unit 2 is used in an extruded state, the British standard hot conductor tab provided on the British standard shared slide base 21 is inserted into the socket hot conductor clip 4, and the British standard neutral conductor tab provided on the British standard shared slide base 21 is inserted into the socket neutral conductor clip 5, thereby achieving a conductive connection between the British standard pin unit 2 and the power converter. When the American standard pin unit 1 is used in an extruded state, the American standard hot conductor tab provided on the American standard shared slide base 11 is inserted into the socket hot conductor clip 4, and the American standard neutral conductor tab provided on the American standard shared slide base 11 is inserted into the socket neutral conductor clip 5, thereby achieving a conductive connection between the American standard pin unit 1 and the power converter. When the European standard pin unit 3 is pushed out for use, the European standard live conductor piece 34 provided on the European standard shared slide base 31 is inserted into the socket live conductor clip 4, and the European standard neutral conductor piece 35 provided on the European standard shared slide base 31 is inserted into the socket neutral conductor clip 5, thereby realizing a conductive connection between the European standard pin unit 3 and the power converter.

[0064] In order to further save space inside the power converter, as shown in FIGS. 14 and 21 to 22, the socket live wire conductive clip 4 is bent upward in a "U" shape to form a European standard live wire conductive retraction slot 41 for retracting the European standard pin unit 3. The socket neutral wire conductive clip 5 is bent upward in a "U" shape to form a European standard neutral wire conductive retraction slot 51 for retracting the European standard pin unit 3. By providing the European standard live wire conductive retraction slot 41 for retracting the European standard pin unit 3 in the socket live wire conductive clip 4, different pin units are connected in the socket live wire conductive clip 4, and the space it occupies overlaps with the European standard pin unit 3, reducing the overall length of the power converter and the overall volume of the power converter, making it more convenient to carry during travel. By providing the European standard neutral wire conductive retraction slot 51 for retracting the European standard pin unit 3 in the socket neutral wire conductive clip 5, different pin units are connected in the socket neutral wire conductive clip 5, and the space it occupies overlaps with the European standard pin unit 3, reducing the overall length of the power converter and the overall volume of the power converter, making it more convenient to carry during travel.

[0065] 21 to 24, the socket live wire conductive clip 4 further includes live wire conductive clips 42 disposed at both ends of the European standard live wire conductive recess 41 for receiving the external plug. The live wire conductive clips 42 may include live wire clamps suitable for various plug models, such as a British standard live wire clamp suitable for the British standard live wire pins of the external plug, a US standard live wire clamp suitable for the US standard live wire pins of the external plug, an Australian standard or Chinese standard live wire clamp suitable for the Australian standard or Chinese standard live wire pins of the external plug, or a European standard live wire clamp suitable for the European standard pins of the external plug, thereby meeting various plug conversion needs and facilitating travel. The staggered arrangement of the various live wire clamps effectively reduces the overall space occupied by the power converter, effectively reducing the overall volume and making it more convenient to carry when traveling.

[0066] 21 to 24, the socket neutral conductor clip 5 includes neutral conductor conductive clips 52 disposed at both ends of the European standard neutral conductor conductive recessing slot 51 and adapted for insertion of an external plug. The socket neutral conductor clip 5 further includes neutral conductor conductive clips 52 disposed at both ends of the European standard neutral conductor recessing slot 51 and adapted for insertion of an external plug. The neutral conductor conductive clips 52 may include neutral conductor clamps adapted to the neutral conductors of various plug models, such as a British standard neutral conductor clamp adapted to the British standard neutral pin of an external plug, an American standard neutral conductor clamp adapted to the American standard neutral pin of an external plug, an Australian standard or Chinese standard neutral conductor clamp adapted to the Australian standard or Chinese standard neutral pin of an external plug, or a European standard neutral conductor clamp adapted to the European standard pin of an external plug, thereby meeting various plug conversion needs and facilitating use during travel. By arranging various neutral wire clamping portions alternately, the overall space occupied is effectively reduced, the overall volume of the power converter is effectively reduced, and it is more convenient to carry when traveling.

[0067] As for other configurations of the socket live wire conductive clip 4 and the socket neutral wire conductive clip 5, their specific structures and operating modes are conventional technologies in the relevant field, and therefore are not particularly limited in this embodiment and may be installed according to actual conditions.

[0068] In order to improve the safety of the power converter, as shown in Figures 14 and 21 to 24, the power converter pin combination structure of the present invention further includes a safety device 6 installed in the power converter, which is connected to the conductive structure in the power converter to protect the circuit of the power converter and effectively improve the safety of the power converter.

[0069] In order to further save space within the power converter, as shown in Figures 15 to 18 and 24, the British Standard shared slide base 21 is recessed into the evacuation space 211 and has a British Standard fuse evacuation section 214 for evacuating the safety device 6, so that the space occupied by the safety device 6 and the space occupied by the British Standard pin unit 2 overlap, thereby further saving space within the power converter, reducing the overall length and volume of the power converter, and making it more convenient to carry when traveling.

[0070] Preferably, as shown in Figures 15 to 18 and 24, the British standard fuse retraction section 214 has an inclined portion near the US standard shared slide base 11. If this portion is used as a space for retracting the US standard shared slide base 11, it becomes easier to push out the US standard pin unit 1 for use, the overall length of the power converter becomes smaller, and the overall volume of the power converter becomes smaller, making it more convenient to carry when traveling.

[0071] Regarding the specific configuration of the safety device 6, the safety device 6 may be a fuse tube, a fuse wire, a fusing device, etc., and may be installed according to the actual situation, and is not particularly limited in this embodiment.

[0072] It should be noted that the compact power converter pin combination structure disclosed in the present invention is an improvement of the specific structure, and the specific control method is not an innovation of the present invention. The US standard hot pin, US standard neutral pin, British standard neutral pin, British standard hot pin, British standard ground pin, European standard hot pin, European standard neutral pin, and other components of the present invention may be general standard components or components known to those skilled in the art, and their structures, principles, and control methods are all known to those skilled in the art through technical manuals, conventional experimental methods, etc.

[0073] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention.
