Description

Technical Field

[0001] This utility model relates to the field of power converter technology, and in particular to a multi-telescopic wire 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 power converters, some power converters feature multiple plug types. Users simply push out the required plug and insert it into the target socket. These plugs are typically standard UK or US plugs. Existing power converters on the market require an additional charging cable to charge portable electronic devices, which consumers often forget to bring, causing significant inconvenience for international business trips. Therefore, some power converters now include a built-in charging cable for consumer use; however, a single charging cable often doesn't meet consumer needs. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide a multi-retractable cable conduction structure for power converters. By incorporating multiple sets of retractable data cables within the power converter, the structure saves space and avoids the need for additional plugs for data retractable cable power conversion.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Please refer to Figures 1 to 7This utility model embodiment provides a multi-telescopic wire conduction structure for a power converter 1, including a power converter 1, a PCB board 2 disposed within the power converter 1, and at least two sets of telescopic wire rotating connection devices (3, 4) disposed within the power converter 1 and electrically connected to the PCB board 2, and an insulating plate 5 spacing the at least two sets of telescopic wire rotating connection devices (3, 4). The telescopic wire rotating connection devices (3, 4) include a first terminal assembly (31, 41) and a second terminal assembly (32, 42) rotatably disposed on the first terminal assembly (31, 41); the first terminal assembly (31, 41) includes a first terminal fixing plate (311, 411); the second terminal assembly (31, 41 ... 32, 42) includes a second terminal fixing plate (321, 421) that can be covered on the first terminal fixing plate (311, 411), and a telescopic wire (322, 422) rotatably disposed between the first terminal fixing plate (311, 411) and the second terminal fixing plate (321, 421). At least one outwardly protruding insulating fixing block (3211, 3212, 4211, 4212) is formed on the second terminal fixing plate (321, 421). At least one outwardly protruding insulating groove (51, 52) is formed on the insulating plate 5 for the insulating fixing block (3211, 3212, 4211, 4212) to be inserted. The telescopic wire rotating connecting devices (3, 4) are not directly connected to each other.

[0035] like Figure 7 As shown, the telescopic rotating connecting device (3, 4) and the PCB board 2 can be connected via a flexible connecting wire, thereby achieving electrical connection. Figures 1 to 3 As shown, the retractable cables (322, 422) in the retractable cable rotating connection devices (3, 4) extend outside the power converter 1. When needed, users can pull the retractable cables (322, 422) out of the power converter 1 to directly charge mobile phones, tablets, etc., avoiding the inconvenience of needing an additional plug and retractable cable for power conversion, thus saving space. By setting at least two sets of retractable cable rotating connection devices inside the power converter 1, at least two sets of retractable cables can be pulled out for use, meeting the needs of charging multiple electrical appliances simultaneously, facilitating daily use, and improving the practicality of the power converter 1. Figures 4 to 6As shown, by forming at least one outwardly protruding insulating fixing block (3211, 3212, 4211, 4212) on the second terminal fixing plate (321, 421), and forming at least one outwardly protruding insulating groove (51, 52) on the insulating plate 5 for inserting the insulating fixing block (3211, 3212, 4211, 4212), the insulating fixing block (3211, 3212, 4211, 4212) is correspondingly inserted into the insulating groove (51, 52). Thus, while fixing multiple sets of second terminal fixing plates (321, 421) to fix the positions of multiple sets of telescopic wire rotating connection devices (3, 4), the second terminal fixing plates (321, 421) are also insulated, thereby effectively preventing the problem of short circuit caused by direct conduction between multiple sets of telescopic wire rotating connection devices (3, 4), and ensuring the safety of this telescopic wire conduction structure.

[0036] Preferred, such as Figures 1 to 3 As shown, in order to make it easier for people to use multiple sets of telescopic cables, the telescopic cables (322, 422) in the rotating connection device of different sets of telescopic cables protrude from the outer shell of the power converter 1 at different positions. That is, the telescopic cables (322, 422) can protrude from different side walls of the power converter 1, thereby effectively avoiding the problem that when the power converter 1 is used, one side wall is blocked by an external object, which would prevent the telescopic cable set on that side wall from being used. This improves the practicality of the power converter 1 and is beneficial to people's daily use.

[0037] The specific structure and principle of the telescopic wire rotating connection device and its connection method with the PCB board are existing technologies. Please refer to the utility model patent with patent number 202420088400.1. Therefore, they will not be described in detail in this embodiment.

[0038] To further prevent short circuits caused by direct contact between the telescopic cable rotating connection devices (3, 4), the first terminal fixing plate (311, 411) and the second terminal fixing plate (321, 421) are made of insulating material, thereby effectively isolating the terminals of multiple sets of telescopic cable rotating connection devices (3, 4) from direct contact and short circuits.

[0039] Preferred, such as Figures 1 to 6 As shown, there are two sets of telescopic cable rotating connection devices, namely a first telescopic cable rotating connection device 3 and a second telescopic cable rotating connection device 4, which are installed in the power converter 1.

[0040] Regarding the specific structural configuration of the first telescopic line rotating connection device 3, as follows: Figures 4 to 6As shown, the first telescopic cable rotating connection device 3 includes a first terminal assembly A 31 disposed within the power converter 1 and a second terminal assembly A 32 rotatably disposed on the first terminal assembly A 31. The first terminal assembly A 31 includes a first terminal fixing plate A 311. The second terminal assembly A 32 includes a second terminal fixing plate A 321 that can cover the first terminal fixing plate A 311 and a telescopic cable A 322 rotatably disposed between the first terminal fixing plate A 311 and the second terminal fixing plate A 321. A left insulating fixing block A 3211 protruding outward is formed on the left side of the second terminal fixing plate A 321, and a right insulating fixing block A 3212 protruding outward is formed on the right side of the second terminal fixing plate A 321. The telescopic cable A 322 extends out of the power converter 1. When needed, the telescopic cable A 322 can be extended by connecting the telescopic cable A 322. The 322 power converter 1 can be pulled out to directly charge mobile phones, tablets, etc., avoiding the trouble of having to configure an additional plug and connect a retractable cable for power conversion, and saving space.

[0041] Regarding the specific structural configuration of the second telescopic line rotary connection device 4, as follows: Figures 4 to 6 As shown, the first telescopic cable rotating connection device 3 includes a first terminal assembly B 41 disposed within the power converter 1 and a second terminal assembly B 42 rotatably disposed on the first terminal assembly B 41; the first terminal assembly B 41 includes a first terminal fixing plate B 411; the second terminal assembly B 42 includes a second terminal fixing plate B 421 that can cover the first terminal fixing plate B 411, and a telescopic cable B 422 rotatably disposed between the first terminal fixing plate B 411 and the second terminal fixing plate B 421; a left insulating fixing block B 4211 protruding outward is formed on the left side of the second terminal fixing plate B 421, and a right insulating fixing block B 4212 protruding outward is formed on the right side of the second terminal fixing plate B 421; the telescopic cable B 422 extends out of the power converter 1, and can be used by extending the telescopic cable B 422 when needed. The 422 power converter 1 can be pulled out to charge mobile phones, tablets, etc. directly, avoiding the trouble of having to configure an additional plug and connect a retractable cable for power conversion, and saving space.

[0042] Regarding the specific manner in which the insulating plate 5 separates the first telescopic wire rotating connection device 3 and the second telescopic wire rotating connection device 4, as follows: Figures 4 to 6As shown, a left insulating groove 51 is formed on the left side of the middle part of the insulating plate 5 for the left insulating fixing block A3211 and the left insulating fixing block B4211 to be inserted, and a right insulating groove 52 is formed on the right side of the middle part of the insulating plate 5 for the right insulating fixing block A3212 and the right insulating fixing block B4212 to be inserted. The second terminal fixing plate A321 and the second terminal fixing plate B421 are arranged adjacent to each other. The left insulating fixing block A3211 on the second terminal fixing plate A321 and the left insulating fixing block B4211 on the second terminal fixing plate B421 are simultaneously placed into the left insulating groove 51 and fixed by the left insulating groove 51. The right insulating fixing block A3212 on the second terminal fixing plate A321 and the right insulating fixing block B4211 are simultaneously placed into the right insulating groove 52 and fixed by the right insulating groove 52. The multiple blocks cooperate with each other to fix the second terminal fixing plate A321 and the second terminal fixing plate B421, thereby fixing the first telescopic wire rotating connecting device 3 and the second telescopic wire rotating connecting device 4. At the same time, it achieves the purpose of insulating the first telescopic wire rotating connecting device 3 and the second telescopic wire rotating connecting device 4, preventing the first telescopic wire rotating connecting device 3 and the second telescopic wire rotating connecting device 4 from being directly connected and causing a short circuit.
