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.

The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] This utility model provides the following technical solution: As attached Figure 1-8 As shown, this utility model discloses a novel converter, including a converter body 1. A cavity 2 is formed within the converter body 1, and a conductive component 3 and a movable connector 4 are disposed within the cavity 2. The movable connector 4 is movably disposed on the inner wall of the converter body 1, and one side of the movable connector 4 is connected to the conductive component 3. The conductive component 3 includes an integrally formed conductive mounting base 5 and a conductive sheet 6 disposed on the conductive mounting base 5. The conductive mounting base 5 has a moving part 7 connected to the movable connector 4 and a mounting part 8 for mounting the conductive sheet 6. In this embodiment, the integrally formed conductive mounting base 5 improves the stability and reliability of the converter's internal structure. By integrating the moving part 7 and the mounting part 8 into a single structure, the fitting gaps and loosening problems that may occur during the assembly of multiple components in traditional designs are avoided. The conductive component 3 fulfills the core function of electrical connection and ensures the stability and safety of current transmission. The integrally formed conductive mounting base 5 not only simplifies the manufacturing process but also reduces the number of contact points in the conductive circuit through structural optimization, thereby reducing resistance loss and the risk of heat generation. The tight fit between the conductive plate 6 and the conductive mounting base 5 ensures the reliability of the electrical connection, maintaining stable performance even under long-term use or vibration environments. Simultaneously, this design facilitates modular production and maintenance; the entire conductive assembly 3 can be quickly disassembled for replacement or repair, improving the maintainability and lifespan of the converter. By integrating the moving part 7 with the mounting part 8, the conductive assembly 3 effectively coordinates the relationship between mechanical movement and electrical connection, enabling the converter to maintain stable electrical performance while meeting flexible connection requirements.

[0023] Furthermore, a guide strip 9 protrudes from the end face of the moving part 7 near the moving connector 4. The side of the moving connector 4 near the moving part 7 connects to the guide strip 9, and the guide strip 9 limits the longitudinal position of the moving connector 4 on the moving part 7. In this embodiment, the function of the moving part 7 is to provide precise and stable movement guidance for the moving connector 4. At least two parallel guide strips 9 form a clear motion trajectory constraint, ensuring that the moving connector 4 maintains the correct position and orientation during longitudinal movement. This design not only effectively prevents possible offset or wobbling of the moving connector 4 during movement, but also reduces wear caused by mechanical friction through the tight fit between the guide strip 9 and the moving connector 4, extending the service life of the component. Simultaneously, the protruding structure of the guide strip 9 enhances the structural strength of the moving part 7, enabling it to better withstand the stress generated during connector movement, ensuring the reliability and stability of the converter during long-term use. In practical applications, this guiding design can adapt to moving connectors 4 of different specifications. By adjusting the spacing and size of the guide strips 9, the versatility and flexibility of the converter are improved. In this embodiment, there are two guide bars 9, and the two guide bars 9 extend along the length direction of the moving part 7 and are parallel.

[0024] Furthermore, the mounting portion 8 is a seat structure protruding from one end face of the moving portion 7. A fixing groove 10 for fixing the conductive component 3 is formed on the mounting portion 8, and the conductive sheet 6 is disposed within the fixing groove 10. In this embodiment, the mounting portion 8 provides a stable and precise mounting platform for the conductive sheet 6. Through the protruding seat structure, the mounting portion 8 not only enhances the overall structural strength of the conductive mounting base 5 but also achieves reliable positioning and fixing of the conductive sheet 6 through the design of the fixing groove 10. This design ensures the positional accuracy of the conductive sheet 6 during installation, avoiding poor electrical contact caused by improper installation. Simultaneously, the size and shape of the fixing groove 10 are precisely designed to closely match the contour of the conductive sheet 6, effectively preventing loosening or displacement of the conductive sheet 6 under vibration or external force. The protruding structure of the mounting portion 8 also maintains a certain safe distance between the conductive sheet 6 and the moving portion 7, further improving the safety and reliability of the converter. In practical applications, this mounting design can adapt to conductive sheets 6 of different specifications, and by adjusting the size and shape of the fixing groove 10, the versatility and flexibility of the converter are improved.

[0025] Furthermore, the converter body 1 includes a panel 11 and a rear cover 12. A movable slot 13 is formed on the rear cover 12, and the movable connector 4 is movably disposed within the movable slot 13, with one end of the connector 4 extending out of the slot 13. In this embodiment, the design of the rear cover 12 and the movable slot 13 provides a stable and constrained movement space for the movable connector 4. The opening position and size of the movable slot 13 are precisely planned to ensure that the movable connector 4 can move smoothly within it, while preventing possible displacement or dislodgement during movement. As an important component of the converter body 1, the rear cover 12 not only protects the internal electrical components from external environmental influences but also achieves precise control of the movable connector 4 through the design of the movable slot 13. This design allows the converter to maintain structural integrity and electrical performance stability while meeting flexible plug-in requirements. In practical applications, the opening size and shape of the movable slot 13 can be adjusted according to the specific specifications of the movable connector 4, thereby improving the converter's versatility and adaptability.

[0026] Furthermore, the panel 11 has a front insertion surface 14 and a bottom insertion surface 15, both of which are provided with insertion holes 16. The conductive sheet 6 includes a live wire conductive sheet 17, a neutral wire conductive sheet 18, and a ground wire conductive sheet 19. The live wire conductive sheet 17 and the neutral wire conductive sheet 18 respectively have a live wire forward insertion portion 20 and a neutral wire forward insertion portion 21 corresponding to the front insertion surface 14, and a live wire bottom insertion portion 22 and a neutral wire bottom insertion portion 23 corresponding to the bottom insertion surface 15. In this embodiment, the panel 11 adopts a dual insertion surface design with both front and bottom insertion surfaces, which significantly improves the space utilization and wiring flexibility of the converter. By providing insertion holes 16 in two different positions, users can choose the optimal insertion method according to the actual installation environment and usage requirements, which is suitable for bottom insertion in horizontal scenarios such as desktops, and also meets the requirements for front insertion in vertical scenarios such as walls. The live wire conductive piece 17 and the neutral wire conductive piece 18 adopt a regional design. Their forward insertion part and bottom insertion part are electrically connected through an integrated live wire conductive piece 17 structure and a neutral wire conductive piece 18 structure. This layout not only ensures the electrical consistency of multi-directional insertion, but also reduces mutual interference when using sockets 16 in different directions through independent insertion areas. The ground wire conductive piece 19, as the core component for safety protection, is provided with an independent insertion position to ensure reliable grounding protection. This multi-directional insertion design not only meets the usage requirements in different scenarios, but also achieves a balance between electrical performance and mechanical reliability through structural optimization, providing a strong guarantee for the stable operation of the converter in complex environments. In this embodiment, the conductive mounting base 5 is also provided with a pressure cover 24 and a safety door 25 on the side near the panel 11. The pressure cover 24 and the safety door 25 can provide safety protection for the converter. Through a movable design, the safety door 25 can automatically close when the pin is not engaged, effectively preventing foreign objects from entering the cavity 2 and avoiding the risk of short circuit caused by accidental contact or conductive impurities. When the latch moves along the guide rail 34 to the connection position, its top will push the safety door 25 to open, ensuring a smooth electrical connection.

[0027] Furthermore, the socket 16 includes at least one three-prong socket 26 and at least one two-prong socket 27 formed on the forward insertion surface 14, and at least one bottom two-prong socket 28 formed on the bottom insertion surface 15. The live wire forward insertion part 20 and the neutral wire forward insertion part 21 have slots 29 corresponding to the three-prong socket 26 and the two-prong socket 27, and the ground wire conductive piece 19 has at least one ground wire slot 30 corresponding to the three-prong socket 26. In this embodiment, the design of the socket 16 fully considers the diverse power needs of users. The three-prong socket 26 is suitable for high-power appliances that require reliable grounding, such as air conditioners and refrigerators, ensuring electrical safety during use; the two-prong socket 27 can meet the power needs of general small appliances, such as table lamps and chargers; the design of the bottom two-prong socket 28 further expands the application scenarios of the converter, allowing it to be conveniently connected to appliances even in space-constrained environments. The corresponding slots 29 of the live wire positive plug 20 and the neutral wire positive plug 21 can accurately mate with the plug pins, ensuring the stability of the electrical connection. The ground wire slot 30 of the ground wire conductive plate 19 provides a reliable grounding path for the appliance, effectively preventing leakage accidents. This socket 16 layout not only improves the versatility of the converter, but also avoids interference when different types of appliances are plugged in through reasonable partitioning design, ensuring stable electrical performance. In practical applications, users can flexibly choose to connect to the positive plug surface 14 or the bottom plug surface 15 according to the type of appliance and plugging requirements, greatly improving the convenience and flexibility of use. In this embodiment, the positive plug surface 14 has two three-prong sockets 26 and two two-prong sockets 27, and the bottom plug surface 15 has two bottom two-prong sockets 28. The live wire conductive plate 17, the neutral wire conductive plate 18, and the ground wire conductive plate 19 are all integrated conductive plate structures.

[0028] Furthermore, a conductive switch 31 is provided on the housing. One end of the conductive switch 31 extends into the cavity 2 and is electrically connected to the conductive sheet 6. The conductive switch 31 controls the on / off state of the conductive sheet 6. In this embodiment, the conductive switch 31 functions to achieve precise control over the on / off state of the conductive sheet 6, thereby ensuring the electrical safety and ease of use of the converter. The conductive switch 31 extending into the cavity 2 and connecting to the conductive sheet 6 allows the switch to sense the electrical state of the conductive sheet 6 in real time and quickly cut off or connect the circuit when needed. When the converter is not in use or requires maintenance, the conductive switch 31 can cut off the circuit of the conductive sheet 6, preventing electrical accidents caused by accidental contact or external factors, and ensuring the personal safety of the user. Simultaneously, when the converter needs to be used, the conductive switch 31 can quickly connect the circuit to ensure normal power supply to the electrical appliance. This design not only improves the safety of the converter but also enhances the user experience by simplifying the operation process. In addition, the precise control function of the conductive switch 31 enables the converter to adapt to the power needs of different electrical appliances. Whether it is a high-power appliance or a small appliance, a stable electrical connection can be achieved through the conductive switch 31. In this embodiment, one end of the conductive switch 31 is fixedly mounted on the rear cover 12, and the other end of the conductive switch extends out of the panel 11. Furthermore, the movable connector 4 has a pin portion 32 and a support portion 33. One side of the support portion 33 is connected to the conductive mounting base 5, and the other side is connected to the rear cover 12. A guide rail 34 protrudes from the rear cover 12, and the support portion 33 is embedded in the guide rail 34, allowing the movable connector 4 to move along the guide rail 34 on the rear cover 12. In this embodiment, the movable connector 4 serves to achieve reliable electrical connection and precise position control between the converter and external devices. The pin portion 32, as the core component of the electrical connection, transmits power to the conductive component 3 via the power supply, and then from the conductive component 3 to the inserted electrical appliance, ensuring the continuity of current transmission. The support portion 33, through its dual connection with the conductive mounting base 5 and the rear cover 12, constructs a stable mechanical support structure. The guide rail 34 is designed to provide a precise movement path for the movable connector 4. Its protruding rear cover 12 not only enhances the rail's strength but also, through its embedded fit with the support 33, effectively restricts the movement direction of the movable connector 4, preventing offset or tilting. This structure allows the movable connector 4 to maintain a smooth movement trajectory during insertion and removal, improving operational convenience and avoiding electrical contact problems caused by mechanical stress. Simultaneously, the fit clearance between the guide rail 34 and the support 33 is precisely calculated to minimize looseness while ensuring smooth movement, thereby guaranteeing the converter's reliability during long-term use.

[0029] Furthermore, the guide rail 34 includes a body portion 35 and a limiting portion 36 disposed on at least one side along the length of the body portion 35. The support portion 33 is provided with an elastic limiting arm 37 corresponding to the limiting portion 36. One end of the elastic limiting arm 37 is provided with a fixed end 38, which extends into the limiting portion 36 for connection. In this embodiment, the limiting portion 36 is specifically designed with a wave-like structure on the body portion 35, and the fixed end 38 is configured to correspond to the wave shape. In other embodiments, the limiting portion may also be a protruding structure, or other structures that can achieve a limiting effect during movement; these will not be listed here. The cooperation mechanism between the guide rail 34 and the support portion 33 achieves precise positioning and reliable limiting of the movable connector 4. The wave-shaped limiting part 36, through its continuously undulating curved surface structure, provides multi-level locking positions for the elastic limiting arm 37. When the movable connector 4 moves along the guide rail 34, the fixed end 38 of the elastic limiting arm 37 will sequentially embed into the troughs of the limiting part 36, forming a positioning effect that can be fixed at each position. This design not only ensures the positional accuracy of the connector during movement, but also absorbs mechanical vibration through elastic deformation, effectively preventing displacement or loosening caused by external impact.

[0030] In this embodiment, a terminal block 39 is also provided inside the support part 33. One side of the terminal block 39 is connected to the pin part 32, and the other side of the terminal block 39 is provided with a wire 40. The wire 40 connects the conductive component 3 and the terminal block 39. Electricity is transmitted to the terminal block 39 through the pin part 32, transmitted to the conductive component 3 through the terminal block 39, and then transmitted to the equipment that needs electricity by the conductive component 3.

[0031] Furthermore, a mounting wall 41 is formed by a partial protrusion on the edge of the end face of the movable part 7 near the movable connector 4, and the mounting wall 41 is in contact with the rear cover 12. In this embodiment, the mounting wall 41 enhances the connection stability between the conductive mounting base 5 and the rear cover 12. The structure of the partially protruding mounting wall 41 not only increases the contact area between the conductive mounting base 5 and the rear cover 12, but also achieves reliable mechanical fixation through precise shape matching. At the same time, it further limits the position of the movable connector 4, preventing possible displacement or shaking during movement, thereby ensuring the stability of the internal structure of the converter and the reliability of the electrical connection.
