Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, and in particular to an integrated small American standard AC plug. Background Technology

[0002] With the widespread use of electric vehicles and various electronic devices, the performance and design optimization of American standard AC plugs, as important electrical connection components, have become increasingly crucial.

[0003] Traditional American standard AC plugs have significant shortcomings. In terms of structural design, they are mostly assembled in a decentralized manner, and the components lack a tight overall integration. This not only makes the plugs large in size, taking up a lot of space and making them inconvenient to carry and store, but also greatly limits their application in some space-constrained usage scenarios, such as inside small charging devices or compact charging areas.

[0004] In terms of connection stability, traditional plugs perform poorly. Frequent plugging and unplugging can easily cause the connecting parts to loosen, resulting in poor contact, which in turn affects charging efficiency and may even cause safety hazards due to unstable current, threatening the safety of equipment and users.

[0005] Safety is also a major drawback of traditional plugs. They lack effective current-blocking devices, meaning that when abnormal current occurs in the circuit, such as overload or short circuit, the current cannot be cut off in time, easily causing equipment damage or even serious accidents such as fires. At the same time, the charging port's protective measures are inadequate, making it susceptible to corrosion from external dust and moisture, reducing the plug's reliability and lifespan. Utility Model Content

[0006] To address some of the problems existing in the prior art, this utility model provides an integrated miniature American standard AC plug. This utility model employs a snap-fit ​​structure combined with limiting and resetting devices to ensure a secure connection; a current interruptor is included to promptly cut off abnormal current and ensure safety. The annular clamping ring and anti-slip texture of the cable fixing assembly securely hold the cable, and the protective design at the charging front extends the plug's lifespan.

[0007] To achieve the above objectives, this utility model provides an integrated small American standard AC plug, including an AC plug body, the AC plug body including a charging gun body, the charging gun body being covered by a main body shell, a charging front end and a charging rear end respectively provided on both sides of the charging gun body, a connecting component provided on the upper part of the side of the charging gun body near the charging front end, a cable fixing component provided on the other side of the charging gun body, and a charging connection part provided with the charging front end.

[0008] As a further improvement of this utility model, in order to make the connection operation more convenient and quick and improve the efficiency of connection and disassembly, the connection component includes a connection protective shell disposed on the main body shell, and a pressing shell that can move up and down is also disposed on one side of the connection protective shell. A buckle plate is disposed below the pressing shell, and a buckle connector is disposed on one side of the buckle plate.

[0009] As a further improvement of this utility model, in order to accurately limit the movement of the buckle plate and prevent the buckle plate from moving excessively or deviating during the pressing process, and to ensure the accuracy and stability of the buckle connection, a limiting structure is provided inside the pressing housing in conjunction with the buckle plate. The limiting structure includes multiple limiting posts provided on the inner wall of the pressing housing and a limiting block provided at the end of the inner wall of the pressing housing.

[0010] As a further improvement of this utility model, in order to realize the connection and separation operation of the buckle and make the operation smoother, a mounting hole is provided on one side of the buckle plate, a cylindrical linkage button is provided inside the mounting hole, the top of the cylindrical linkage button is connected to the housing, and a fixing block is provided on one side of the cylindrical linkage button.

[0011] As a further improvement of this utility model, in order to accurately trigger the blocking switch of the current interruptor by pressing the rib plate and realize the rapid cutting off of the current, thereby further improving the safety of the plug, a current interruptor is provided on the lower side of one side of the buckle plate, a blocking switch is provided on one side of the upper part of the current interruptor, and a pressing rib plate is provided on the other side. The end of the pressing rib plate is provided between the current interruptor and the fixing block, and the end of the pressing rib plate is vertically arranged with the current interruptor and the fixing block.

[0012] As a further improvement of this utility model, in order to enable the buckle plate to rotate around the rotation axis and achieve flexible movement of the buckle plate, so that the buckle plate can automatically reset after the pressing operation is completed and return to the initial state, facilitating the next connection operation and improving the convenience and efficiency of use, the main body shell is provided with fixing blocks on both sides, the buckle plate is provided with connecting blocks on both sides, and a rotation axis is provided between the two fixing blocks. The buckle plate is set on the rotation axis through the connecting blocks, and a reset spring is provided on the rotation axis between the two connecting blocks.

[0013] As a further improvement of this utility model, in order to prevent the cable from loosening or falling off during use and to ensure the stability of current transmission, the cable fixing assembly includes one or more annular clamping rings, the inner wall of which is provided with anti-slip texture and contacts the cable sheath.

[0014] As a further improvement of this utility model, in order to prevent external dust, moisture and other substances from entering the charging port and extend the service life of the charging port, a protective ring is provided on the inner side of the charging front end, and a number of charging ports are provided inside the protective ring. The charging port is provided with a terminal fixing module for fixing.

[0015] When this invention is in operation, first ensure that the charging device and the charging connector are compatible. Hold the charging gun and align the charging tip with the charging interface of the device to be charged. Slowly approach and insert it, ensuring that the charging connector fits tightly against the device interface. At this time, the protective ring at the charging tip effectively prevents external impurities from entering the charging port, and the internal terminal fixing module ensures a stable terminal connection and smooth current transmission.

[0016] Next, perform the connection locking operation. Press the pressing housing on the connecting assembly with your finger. The pressing housing moves downward, and its internal multi-layered limiting posts and blocks precisely limit the movement to prevent excessive pressing. The pressing housing drives the cylindrical linkage button downward. The cylindrical linkage button drives the buckle plate to rotate around the rotating axis through the mounting hole. The connecting blocks on both sides of the buckle plate rotate on the rotating axis, and at the same time, the return spring is compressed. The fixed pressure block located on one side of the cylindrical linkage button moves downward and comes into contact with the pressing rib plate. Under the linkage action of the pressing rib plate, the internal circuit is connected, and the current can pass normally. The rotation of the buckle plate causes the buckle connector to engage with the corresponding buckle structure on the device to be charged, realizing a firm connection between the charging gun body and the device.

[0017] The cable is then secured using the cable fixing assembly. The cable is placed inside the annular clamping ring; the anti-slip texture on the inner wall of the clamping ring increases friction with the cable sheath, preventing the cable from loosening and falling off, and ensuring cable stability during charging.

[0018] After charging is complete, press the housing down again. This will rotate the locking plate via the cylindrical linkage button. As the button moves slightly downwards under pressure, the fixing block on one side of the button moves downwards and contacts the pressing rib plate. The internal circuit is then disconnected by the pressing rib plate, separating the locking connector from the device's locking structure. The locking plate automatically returns to its initial state under the action of the return spring. Finally, remove the charging gun from the device to be charged, completing the charging process.

[0019] The beneficial effects of this utility model are as follows:

[0020] Secure connection and easy operation: The connection components are ingeniously designed, and the protective housing effectively protects the internal structure. The movable press-fit housing, along with the snap-fit ​​plate and snap-fit ​​connector, allows for quick connection and disconnection of the plug and device with a simple press, saving time and effort. Multiple limiting posts and blocks within the press-fit housing precisely limit the pressing stroke, preventing excessive pressure from damaging components and ensuring the stability and reliability of the connection operation. The snap-fit ​​plate is mounted on the main housing via a rotating shaft and a return spring, automatically resetting after connection and disconnection for easy next use.

[0021] Reliable cable fixing: The inner wall of the annular clamping ring of the cable fixing assembly is provided with anti-slip texture, which can increase the friction with the cable sheath, effectively prevent the cable from loosening or falling off during use, ensure the stability of current transmission, and reduce safety hazards caused by poor contact.

[0022] The charging port is well protected: the protective ring on the inner side of the charging front prevents dust and moisture from entering the charging port, extending its lifespan. The internal terminal fixing module ensures stability when the terminal is connected to the device, improving charging efficiency and quality. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solutions in this application, the following description is provided in conjunction with the appendix. Figure 1-7 The present invention will be further described below. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the protection scope of the present invention.

[0033] like Figure 1-7 The diagram shows an integrated miniature American standard AC plug, including an AC plug body, which includes a charging gun body 1. The charging gun body 1 is covered by a main body shell 2. A charging front end 3 and a charging rear end 4 are respectively provided on both sides of the charging gun body 1. A connecting component 5 is provided on the upper part of the side of the charging gun body 1 near the charging front end 3. A cable fixing component 6 is provided on the other side of the charging gun body 1. A charging connection part 7 is provided in cooperation with the charging front end 3.

[0034] The connecting component 5 includes a connecting protective housing 8 disposed on the main body shell 2. A pressing housing 9 that can move up and down is also provided on one side of the connecting protective housing 8. A buckle plate 10 is provided below the pressing housing 9. A buckle connector 11 is provided on one side of the buckle plate 10.

[0035] The inside of the pressing housing 9 is equipped with a buckle plate 10 and a limiting structure 12. The limiting structure 12 includes multiple limiting posts 13 disposed on the inner wall of the pressing housing 9 and a limiting block 14 disposed at the end of the inner wall of the pressing housing 9.

[0036] A mounting hole 15 is provided on one side of the buckle plate 10. A cylindrical linkage button 16 is provided inside the mounting hole 15. The top of the cylindrical linkage button 16 is connected to the housing 9. A fixing block 17 is provided on one side of the cylindrical linkage button 16.

[0037] A current blocker 18 is provided on one side of the buckle plate 10. A blocking switch 19 is provided on one side of the upper part of the current blocker 18, and a pressing rib plate 20 is provided on the other side. The end of the pressing rib plate 20 is located between the current blocker 18 and the fixing block 17. The end of the pressing rib plate 20 is vertically arranged with the current blocker 18 and the fixing block 17.

[0038] The main body shell 2 is provided with fixing blocks 21 on both sides, the buckle plate 10 is provided with connecting blocks 22 on both sides, and a rotating shaft 23 is provided between the two fixing blocks 21. The buckle plate 10 is mounted on the rotating shaft 23 through the connecting blocks 22. A return spring 24 is provided on the rotating shaft 23 between the two connecting blocks 22.

[0039] The cable fixing assembly 6 includes one or more annular clamping rings 25, the inner wall of which is provided with anti-slip texture and contacts the cable sheath.

[0040] The inner side of the charging front end 3 is provided with a protective ring 26, and a number of charging ports 27 are provided inside the protective ring 26. The charging ports 27 are provided with terminal fixing modules 28 for fixing.

[0041] When this utility model is in operation, first ensure that the charging device matches the charging connection part 7. Hold the charging gun body 1, align the charging front end 3 with the charging interface of the device to be charged, slowly approach and insert it, so that the charging connection part 7 fits tightly with the device interface. At this time, the protective ring 26 of the charging front end 3 can effectively prevent external impurities from entering the charging port 27, and the internal terminal fixing module 28 ensures a stable terminal connection and ensures smooth current transmission.

[0042] Next, the connection locking operation is performed. Press the pressing housing 9 on the connecting assembly 5 with your finger. The pressing housing 9 moves downward, and the multi-layer limiting posts 13 and limiting blocks 14 inside precisely limit the movement to prevent excessive pressing. The pressing housing 9 drives the cylindrical linkage button 16 to move downward. The cylindrical linkage button 16 drives the buckle plate 10 to rotate around the rotating shaft 23 through the mounting hole 15. The connecting blocks 22 on both sides of the buckle plate 10 rotate on the rotating shaft 23, and at the same time, the return spring 24 is compressed. The fixed pressure block 17 located on one side of the cylindrical linkage button 16 moves downward and comes into contact with the pressing rib plate 20. Under the linkage action of the pressing rib plate 20, the internal circuit is connected and the current can pass normally. The rotation of the buckle plate 10 causes the buckle connector 11 to engage with the corresponding buckle structure on the device to be charged, realizing a firm connection between the charging gun body 1 and the device.

[0043] The cable is then secured using the cable fixing assembly 6. The cable is placed inside the annular clamping ring 25. The anti-slip texture on the inner wall of the annular clamping ring 25 increases the friction with the cable sheath, preventing the cable from loosening and falling off, and ensuring the stability of the cable during charging.

[0044] After charging is complete, press down on the housing 9 again. This will cause the cylindrical linkage button 16 to rotate the latch plate 10. As the cylindrical linkage button 16 moves slightly downward under pressure, the fixing block 17 on one side of the cylindrical linkage button 16 moves downward and contacts the pressing rib plate 20. Under the linkage action of the pressing rib plate 20, the internal circuit is disconnected, causing the latch connector 11 to separate from the device's latching structure. Under the action of the return spring 24, the latch plate 10 automatically returns to its initial state. Finally, pull the charging gun body 1 out of the device to be charged to complete the entire charging process.

[0045] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
