Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, and in particular to a multi-interface combined power adapter. Background Technology

[0002] Power adapters, as indispensable accessories for smartphones, laptops, and other portable electronic devices, primarily function to convert standard AC power into the low-voltage DC power required by these devices. With the acceleration of globalization and the increasing frequency of business and tourism activities, it has become commonplace for people to carry electronic devices across regions and countries. However, there are significant differences in electrical outlet standards between different countries and regions. Traditional power adapters typically use a fixed plug integrated into the adapter itself. This design means that it can only be used in a specific country or region. When traveling internationally, users have to carry multiple chargers of different specifications or bulky adapters, greatly increasing the burden of travel and reducing convenience.

[0003] Furthermore, during daily use, users often need to operate the device while charging, such as answering calls, browsing information, or moving. In such dynamic usage scenarios, the connector of the data cable connected to the USB or Type-C interface of the power adapter is frequently subjected to external forces such as pulling, shaking, and twisting. Existing connection methods rely solely on the friction and holding force of the interface and connector for fixation. This connection force is relatively weak and easily leads to poor contact due to external interference, causing charging interruptions and data transmission failures. More seriously, long-term shaking and stress concentration may also accelerate the wear and damage of the adapter interface and data cable connector, shortening the product's lifespan and posing safety hazards. Therefore, this utility model proposes a multi-interface combination power adapter to address the shortcomings of existing technologies. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-interface combination power adapter, which aims to improve the problems of existing power adapters, such as fixed single plug type, poor compatibility for cross-regional use, low reliability of data cable connection, and easy loosening and detachment due to external pulling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-interface combination power adapter includes: an adapter body, a plug, a connecting block disposed on the adapter body; a limiting component disposed on the adapter body, and a disassembly / removal component for connecting the plug and the connecting block.

[0006] The disassembly and assembly assembly includes a threaded block formed on the plug and a threaded groove formed on the connecting block.

[0007] Furthermore, the plug and the connecting block are detachably connected by the threaded block and the threaded groove in a threaded engagement manner; the limiting component includes a slidable limiting plate and a screw for fixing the limiting plate.

[0008] Preferably, the plug is provided with a first conductive piece, and the connecting block is provided with a second conductive piece. When the plug is connected to the connecting block, the first conductive piece and the second conductive piece are interlocked.

[0009] Preferably, the limiting component further includes a mounting cover fixed to the adapter body, the mounting cover having a sliding groove, and the limiting plate being slidably disposed in the mounting cover via the sliding groove.

[0010] Preferably, the mounting cover is provided with a second threaded groove, and the screw passes through the limiting plate and is threadedly connected to the second threaded groove.

[0011] Preferably, a pull rod is connected to the limiting plate to facilitate the user to push and pull the limiting plate.

[0012] Preferably, the limiting plate has a limiting groove for constraining the data cable body.

[0013] Preferably, the adapter body is provided with a USB interface and a Type-C interface, and the limiting component is disposed on the outside of the USB interface and the Type-C interface.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a disassembly and assembly component consisting of a threaded block and a threaded groove, the plug and the connecting block are detachably threadedly connected, which solves the problem of incompatibility and poor universality of existing power adapters due to fixed plug types when used in different regions. It achieves the technical effect of allowing different plug specifications to be combined into one adapter body, thereby improving the applicability and convenience of the equipment.

[0015] 2. In this utility model, by setting a limiting component including a sliding limiting plate and a locking screw on the adapter body, the limiting groove on the limiting plate is used to physically limit and fix the data cable inserted into the USB interface or Type-C interface, which solves the problem of the data cable connection being not firm and easily loosened or falling off due to pulling, and achieves the technical effects of stable connection, preventing charging interruption, and protecting the interface and connector.

[0016] 3. The overall structure of this utility model is ingenious and compact, integrating the plug replacement function with the data cable fixing function. The threaded connection of the disassembly and assembly components ensures the stability and electrical reliability after plug replacement. The sliding locking structure of the limit component is intuitive to operate, effectively improving the reliability and durability of the product in various complex usage environments.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Please refer to the accompanying drawings. This utility model provides a multi-interface combination power adapter, which aims to solve the problems of existing power adapters having a single plug type, poor applicability, and unstable data cable connection that is easy to fall off. The multi-interface combination power adapter includes an adapter body 1, a plug 3, and a connecting block 2. The connecting block 2 is fixedly disposed at one end of the adapter body 1, and the plug 3 is installed on the side of the connecting block 2 away from the adapter body 1.

[0024] In this embodiment, the plug 3 and the connecting block 2 are detachably connected by the disassembly and assembly component 8, and a limiting component 6 for fixing the data cable is provided on the adapter body 1.

[0025] Specifically, the detachable structure between the plug 3 and the connecting block 2 is a disassembly assembly 8. The disassembly assembly 8 consists of a threaded block 801 formed at the end of the plug 3 and a threaded groove 802 formed on the connecting block 2. The threaded block 801 and the threaded groove 802 are connected and separated by threaded engagement. A conductive sheet 9 is also fixedly provided on the connecting end face of the plug 3. A conductive sheet 10 is provided at a corresponding position inside the connecting block 2. When the threaded block 801 is fully screwed into the threaded groove 802, the conductive sheet 9 and the conductive sheet 10 are tightly engaged to form a conductive path.

[0026] The adapter body 1 is also fixed with a limiting component 6. The limiting component 6 is located at the other end of the adapter body 1. This end of the adapter body 1 is provided with a USB interface 12 and a Type-C interface 13. The limiting component 6 includes a mounting cover 602 fixedly connected to the adapter body 1. The mounting cover 602 has a sliding groove 4 inside. The limiting plate 601 is located inside the mounting cover 602 and is slidably connected by cooperating with the sliding groove 4. The limiting plate 601 has a limiting groove 7. One end of the limiting plate 601 extends to form a pull rod 5. The mounting cover 602 also has a threaded groove 11. A screw 603 passes through the limiting plate 601 and is threadedly engaged with the threaded groove 11. By rotating the screw 603, the limiting plate 601 can be locked in any sliding position inside the mounting cover 602.

[0027] The AC / DC conversion circuit inside the adapter body 1 is a well-known technology in the field and will not be described in detail here.

[0028] As a preferred embodiment, the disassembly and assembly component 8 is composed of a threaded block 801 on the plug 3 and a threaded groove 802 on the connecting block 2. The plug 3 can be quickly replaced by screwing the threaded block 801 and the threaded groove 802 together and separating them. A conductive sheet 9 is fixed on the end face of the plug 3, and a conductive sheet 10 is fixed inside the connecting block 2. The conductive sheet 9 and the conductive sheet 10 are used to contact each other after the plug 3 is installed in place so as to connect the power supply.

[0029] As another preferred embodiment, the limiting component 6 is specifically constructed as follows: a mounting cover 602 is fixedly installed on the adapter body 1, a sliding groove 4 is formed on the inner wall of the mounting cover 602, and a limiting plate 601 is installed inside the mounting cover 602 by slidingly engaging with the sliding groove 4. The limiting plate 601 is provided with a limiting groove 7 for holding the data cable, and the limiting plate 601 is also connected to a pull rod 5 for conveniently pushing or pulling the limiting plate 601. The mounting cover 602 is also provided with a threaded groove 11, and a screw 603 is threadedly engaged with the threaded groove 11 to fix the limiting plate 601 in the desired position.

[0030] As another preferred embodiment, the adapter body 1 integrates both a USB interface 12 and a Type-C interface 13 to meet the charging needs of different electronic devices. The limiting component 6 is positioned directly opposite the outside of the USB interface 12 and the Type-C interface 13 to effectively fix the data cable inserted into either interface.

[0031] Working principle: When using the device, if it is necessary to replace the plug 3 according to the type of the power strip interface, the plug 3 can be twisted outward first. At this time, the threaded block 801 in the disassembly and assembly assembly 8 rotates outward in the threaded groove 802. The conductive piece 9 and the conductive piece 10 gradually disengage as the plug 3 moves outward until the threaded block 801 disengages from the connecting block 2. Then, find the corresponding plug 3, align the threaded block 801 with the threaded groove 802, and then rotate it inward. Under the action of the threaded block 801 and the threaded groove 802, the plug 3 gradually approaches the connecting block 2. At the same time, the conductive piece 9 also gradually approaches the conductive piece 10 until the plug 3 is fixed on the outside of the connecting block 2. At this time, the conductive piece 9 and the conductive piece 10 are tightly engaged with each other, thus completing the replacement of the plug 3.

[0032] When it is necessary to fix the data cable, first insert the data cable connector into the USB interface 12 or Type-C interface 13 on the outside of the adapter body 1. Then, push the limiting plate 601 in the limiting assembly 6 inward by pulling the lever 5. At this time, the limiting plate 601 slides inward in the middle of the mounting cover 602 through the sliding groove 4, and the limiting groove 7 slides close to the outside of the data cable until it slides to the innermost side of the mounting cover 602. Then, turn the two screws 603 inward. Under the action of the threaded groove 11, the screws 603 fix the limiting plate 601 in the middle of the mounting cover 602. At this time, the data cable connector is restricted from moving back and forth under the action of the limiting plate 601, so that the data cable connector can be stably installed in the USB interface 12 or Type-C interface 13.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
