Description

Technical Field

[0001] This utility model relates to the field of power converter technology, and in particular to a circuit board conduction structure for power converters. Background Technology

[0002] Because plugs and sockets differ from country to country, they are not interchangeable. If you need to insert a plug into an incompatible socket, you will need a power adapter. A power adapter is an conversion tool; to use it, you plug the adapter into the target socket and then insert the target plug into the matching socket on the adapter. Power adapters have greatly improved the convenience of traveling, especially when traveling internationally, eliminating worries about incompatibility between the plugs of your electronic devices and local power outlets.

[0003] To improve the versatility of converters, existing power converters often include USB or Type-C ports on their circuit boards, saving users the space of carrying an extra plug. However, most power converters on the market only have one port per circuit board, which cannot meet users' needs for using multiple data cables simultaneously. Furthermore, most power converters on the market lack safety features, offering low security. At most, they may have an internal fuse, but users have no way of knowing the status of the power converter during use, potentially leading to safety hazards. Utility Model Content

[0030] The beneficial effects of this utility model are as follows:

[0031] (1) By configuring the circuit board's conductive structure to include a power converter, at least two sets of circuit boards disposed within the power converter, a neutral wire conductive component disposed within the power converter and electrically connected to the circuit boards, a live wire conductive component disposed within the power converter and electrically connected to the circuit boards, and a fuse disposed within the power converter and connected to the live wire conductive component, the live wire conductive component includes a first live wire connecting piece disposed within the power converter and electrically connected to the circuit boards, a second live wire connecting piece connected to the first live wire connecting piece and electrically connected to the circuit boards, and a fuse disposed between the first live wire connecting piece and the circuit boards.

[0032] By arranging at least two sets of circuit boards on the power converter, which can be arranged opposite each other or on different side walls of the power converter, the interfaces on the circuit boards can be located on different side walls of the power converter. This effectively avoids the problem of one side of the power converter being blocked by external objects, making the charging interface unusable or the indicator light unobservable. Furthermore, the structure of multiple sets of circuit boards allows for a greater number of charging interfaces or indicator lights, or even the simultaneous arrangement of charging interfaces and indicator lights. This satisfies people's charging needs in terms of the number of interfaces and the safety requirements for observing the power converter's usage, facilitating daily use and improving the practicality of the power converter. The live wire connection assembly has a first live wire connecting piece electrically connected to the circuit board, and a second live wire connecting piece electrically connected to the circuit board. The first live wire connecting piece is connected to the live wire socket connection clip via a fuse. An external socket to be converted is inserted into the live wire socket connection clip. The neutral wire connection assembly has a first neutral wire connecting piece electrically connected to the circuit board, and a second neutral wire connecting piece electrically connected to the circuit board. The first neutral wire connecting piece is connected to the neutral wire socket connection clip. An external socket to be converted is inserted into the neutral wire socket connection clip. This allows for the conversion of the external socket's pins while simultaneously ensuring stable power transmission between the interface and / or indicator light on the circuit board and the power converter. This facilitates the direct insertion of an external charging cable into the charging interface and allows users to monitor the power converter's status via indicator lights, ensuring the power converter's safety. By setting a safety element between the first live wire connecting piece and the live wire socket conductive clamp, and the first safety clamping part and the second safety clamping part correspondingly clamping the safety element, the first live wire connecting piece is connected to the live wire socket conductive clamp, realizing the conductive connection of the entire live wire conductive assembly.

By providing a second live wire connecting piece and a third live wire connecting piece to the circuit board on the live wire conducting assembly, and the second live wire connecting piece being connected to the live wire socket conducting clip via a fuse, the external socket to be converted is inserted into the live wire socket conducting clip. Similarly, by providing a second neutral wire connecting piece and a third neutral wire connecting piece to the circuit board on the neutral wire conducting assembly, and the second neutral wire connecting piece being connected to the neutral wire socket conducting clip, the external socket to be converted is inserted into the neutral wire socket conducting clip.

[0074] Example 1

[0075] Please refer to Figures 1 to 16 This utility model embodiment provides a circuit board conduction structure for a power converter 1, including a power converter 1, at least two circuit boards disposed within the power converter 1, a neutral wire conduction component 5 disposed within the power converter 1 and electrically connected to the circuit boards, a live wire conduction component 4 disposed within the power converter 1 and electrically connected to the circuit boards, and a fuse 6 disposed within the power converter 1 and connected to the live wire conduction component 4. The live wire conduction component 4 includes a first live wire connecting piece 41 disposed within the power converter 1 and electrically connected to the circuit boards, a second live wire connecting piece 42 connected to the first live wire connecting piece 41 and electrically connected to the circuit boards, and a fuse 6 disposed within the first live wire connecting piece 41. The circuit includes a first safety clamping part 43 that clamps the lower end of the fuse 6 between the first safety clamp 41 and the second live wire connecting piece 42; a live wire socket conductive clip 44 disposed on the power converter 1; and a second safety clamping part 45 disposed on the live wire socket conductive clip 44 that clamps the upper end of the fuse 6. The neutral wire conductive assembly 5 includes a first neutral wire connecting piece 51 disposed inside the power converter 1 and electrically connected to the circuit board; a second neutral wire connecting piece 52 connected to the first neutral wire connecting piece 51 and electrically connected to the circuit board; and a neutral wire socket conductive clip 53 disposed on the power converter 1 and electrically connected to the first neutral wire connecting piece 51. The circuit board is provided with a charging interface and / or an indicator light.

[0076] By setting at least two sets of circuit boards on the power converter 1, the circuit boards can be arranged opposite each other or on different side walls of the power converter 1, so that the charging interfaces on the circuit boards can be set on different side walls of the power converter 1. This effectively avoids the problem that the charging interfaces or indicator lights on one side of the power converter 1 cannot be used or cannot be observed because they are blocked by external objects when in use. Furthermore, the structure of multiple sets of circuit boards allows for more charging interfaces or more indicator lights, or even simultaneous installation of charging interfaces and indicator lights, thereby meeting people's charging needs in terms of the number of interfaces and safety needs for observing the use of the power converter 1, which is beneficial for people's daily use and improves the practicality of the power converter 1. The live wire connection assembly 4 has a first live wire connecting piece 41 electrically connected to the circuit board, and a second live wire connecting piece 42 electrically connected to the circuit board. The first live wire connecting piece 41 is connected to the live wire socket connection clip 44 via a fuse 6. An external socket to be converted is inserted into the live wire socket connection clip 44. The neutral wire connection assembly 5 has a first neutral wire connecting piece 51 electrically connected to the circuit board, and a second neutral wire connecting piece 52 electrically connected to the circuit board. The first neutral wire connecting piece 51 is connected to the neutral wire socket connection clip 53. An external socket to be converted is inserted into the neutral wire socket connection clip 53. This allows for the conversion of the external socket's pins while simultaneously ensuring stable power transmission between the interface and / or indicator light on the circuit board and the power converter 1. This facilitates the direct insertion of an external charging cable into the charging interface for charging and allows users to monitor the power converter 1's usage status through indicator lights, ensuring the safety of the power converter 1. By setting a safety element 6 between the first live wire connecting piece 41 and the live wire socket conductive clamp 44, and the first safety clamping part 43 and the second safety clamping part 45 respectively clamping the safety element 6, the first live wire connecting piece 41 is connected to the live wire socket conductive clamp 44, realizing the conductive connection of the entire live wire conductive assembly 4. The safety element 6 melts and cuts off the current when the current of the live wire conductive assembly 4 rises abnormally, thereby protecting the internal circuit of the power converter 1 and improving the safety of the power converter 1.

[0077] Regarding the specific settings of the charging interface, as follows: Figures 1 to 16As shown, the charging interface is one or a combination of Standard Type-A USB interface, Micro Type-B interface, Type-C interface, and Lightning interface. The choice can be made according to the actual situation, so no specific limitation is made in this embodiment. The Standard Type-A USB interface, Micro Type-B interface, Type-C interface, and Lightning interface mentioned above are all conventional components in the art, and their structures and principles are existing technologies, so they will not be described in detail in this embodiment.

[0078] Regarding the specific settings of the indicator lights, such as Figures 1 to 16 As shown, the indicator light is one or a combination of surge protection indicator light and voltage indicator light, which can be selected according to the actual situation. Therefore, no specific limitation is made in this embodiment.
