Technical Field

[0001] This application relates to the field of power supply structure technology, and more particularly to an adapter. Background Technology

[0002] Currently, power supplies on the market are mainly divided into two designs: wall-mounted and desktop. Wall-mounted power supplies typically use fixed plugs to accommodate different national or regional standards, such as Chinese CCC, European EU, American UL, Australian AU, or British UK. Desktop power supplies, on the other hand, mostly use power sockets designed to work with AC cables (such as C6, C8, or C14), and are connected via corresponding power cables. When users need to switch between different specifications of wall-mounted and desktop power supplies, they often need to use an adapter, which is inconvenient. Utility Model Content

Detailed Implementation

[0032] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0033] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0034] The inventors discovered that when traveling or on business trips internationally, one encounters different wall socket specifications in various countries. This necessitates carrying multiple adapters to adapt to different power outlets, increasing the weight and volume of luggage. Furthermore, at home or in the office, different types of power outlets are required, such as converting from a wall socket to a desktop power outlet. This necessitates frequently changing or carrying adapters, causing inconvenience.

[0035] The first aspect of this application provides an adapter, as shown in the appendix. Figure 1 - Appendix Figure 13 The adapter includes: an adapter body 1, which has an output port 101 for supplying first power to an electronic device and an input port 102 for receiving second power. The input port 102 is provided with a connection terminal 103 and a first connection structure 104. A connector 2 includes a first plug portion 22 for connecting to the input port 102 and a second connection structure 21 for detachably connecting to the adapter body 1. The connector 2 can be detachably connected to the adapter body 1 through the cooperation between the second connection structure 21 and the first connection structure 104. When the connector 2 and the adapter body 1 are in a connected state, the connection terminal 103 is plugged into the first plug portion 22. The connector 2 also includes a second plug portion 23 electrically connected to the first plug portion 22. The second plug portion 23 can be connected to a first type of power supply and / or a second type of power supply.

[0036] In one possible case, such as Figure 1 As shown, the adapter body 1 is the core component of the entire adapter, including a housing and a circuit module located inside the housing, used to convert the specifications of the input current or input voltage (such as voltage adjustment to convert 220V voltage to 5V voltage, 12V voltage, etc.). The adapters of this application include, but are not limited to, AC adapters, DC adapters, etc. The output port 101 is used to output first power to electronic devices, including but not limited to laptops, mobile phones, tablets, etc. The output port 101 can be a USB interface, a Type-C interface, a Type-A interface, etc. The input port 102 of the adapter body 1 can be used to obtain second power, and can establish a physical connection with an external power source (such as a wall socket or power cord) through the connection terminal 103. The connection terminal 103 is the main channel for current to enter the adapter. It may contain metal contacts or spring contacts that can tightly contact the corresponding part of the external power plug or socket to ensure that the current flows into the adapter stably and efficiently. Here, the first power can be the electrical energy specification provided by the adapter to the electronic device through its output port 101, while the second power refers to the electrical energy specification obtained by the adapter from the external power source. For example: the first power source is 5V / 2A DC power, with a total power of 10W, and the second power source is 220V AC power obtained from a household socket.

[0037] The first connecting structure 104 is used to achieve a mechanical connection with the second connecting structure 21 of the plug 2, so that the connecting terminal 103 and the first plug portion 22 always remain in contact to achieve an electrical connection. The first connecting structure 104 may include an annular groove (not shown in the figure) disposed around the input port 102, and the second connecting structure 21 may include an annular flange, which enters the annular groove when the plug 2 is inserted to achieve a detachable connection; or the first connecting structure 104 and the second connecting structure 21 may both include magnetic elements to achieve a detachable connection through magnetic attraction.

[0038] like Figure 3 , Figure 4 , Figure 7 , Figure 8As shown, the first plug-in portion 22 is part of the plug connector 2 and makes direct electrical contact with the connection terminal 103 on the adapter body 1. The bottom of the plug connector 2 has a clearance groove 25, which is adapted to the shape and position of the connection terminal 103 to provide clearance space for the connection terminal 103 when the plug connector 2 is inserted into the slot 1041. The first plug-in portion 22 is placed within the clearance groove 25. The first plug-in portion 22 can consist of multiple metal pins, the number and arrangement of which are set according to actual needs: such as two pins or three pins (not shown in the figure). The connection terminal 103 can be a set of metal sockets that match the metal pins or metal pins protruding from the adapter body 1. When the plug connector 2 is inserted, the pins enter the socket and make tight contact with the socket wall, or the pins of the plug connector 2 contact the metal pins of the adapter body 1, completing the electrical connection. Alternatively, the first plug-in portion 22 can be a flat metal plate or metal ring with a polished surface to reduce contact resistance. The metal plate has positioning grooves or protrusions for alignment with the adapter body 1. The connecting terminal 103 is a set of planar metal contacts that are fully fitted to the metal plate of the first plug-in portion 22. After the plug-in 2 is inserted, a large-area contact is formed between the metal plate and the contacts, reducing resistance. The plug-in 2 can also integrate a second plug-in portion 23 for first-type and / or second-type power input. The second plug-in portion 23 can simultaneously connect to one first-type power supply, or one second-type power supply, or both. The second plug-in portion 23 can be a fixed plug, customized according to the power supply standard of the target market (e.g., two-prong flat plug, two-cylinder plug, etc.). The second plug-in portion 23 can simultaneously integrate a fixed plug and a pluggable socket module to enable connection of different types of power supplies through a single plug-in 2. For example, one side of the plug-in 2 is a fixed plug, and the other side is a socket that can accept various standard AC cables, allowing users to choose which method to use for power connection according to their actual needs. In addition, inside the connector 2, the first connector 22 and the second connector 23 are connected together by a highly conductive metal sheet or wire to ensure that the current can be smoothly transmitted from the second connector 23 to the first connector 22 and finally reach the adapter body 1.

[0039] This application provides an adapter that solves the problem of traditional power adapters requiring additional adapters when changing usage scenarios. By detachably connecting the connector 2 to the adapter body 1 and replacing different second connectors 23, the connector 2 gains wider applicability. Whether facing standard plugs from different countries or requiring AC cable connections, users can easily switch between wall-mounted and desktop modes simply by replacing the corresponding connector 2, eliminating the need to carry multiple adapters or complex conversion devices. This improves the flexibility and convenience of adapter use, enabling stable operation in various environments and meeting diverse needs.

[0040] In some embodiments, the connector 2 includes a second plug portion 23 of a first type for connection to a first type of power source; or, the connector 2 includes a second plug portion 23 of a second type for connection to a second type of power source; or, the connector 2 includes second plug portions 23 of different types for electrical connection to a first type of power source and a second type of power source, respectively.

[0041] In one possible scenario, the adapter's connector 2 may include a first type of second connector 23 and a second type of second connector 23. Connectors 2 equipped with different second connectors 23 can respectively adapt to a first type of power supply (e.g., a wall-mounted plug) and a second type of power supply (e.g., a desktop socket). Equipping the adapter with different second connectors 23 can enhance its versatility and flexibility. Figure 3 As shown, the second plug portion 23 of the first type protrudes from the plug surface 24 of the plug 2, enabling it to establish a more stable connection with an external power source (such as a wall socket or AC cable). This is suitable for scenarios requiring frequent plugging and unplugging (such as wall-mounted plug 2 used during travel), reducing contact problems caused by unstable plugging. Figure 7 As shown, the plug surface 24 of the connector 2 has a receiving groove, and the second type of second plug portion 23 protrudes from the bottom surface of the receiving groove and is partially exposed within the receiving groove. By providing a receiving groove on the plug surface 24 and partially exposing the second type of second plug portion 23 within the receiving groove, the overall size of the connector 2 can be effectively reduced, improving portability. This makes it suitable for scenarios where frequent replacement of the connector 2 is not required or where portability is a high priority (such as desktop connector 2), while also protecting the second plug portion 23 from physical damage. Furthermore, the first type of second plug portion 23 and the second type of plug portion 23 can be integrated into a single connector 2 for use in scenarios requiring dual power supplies.

[0042] In some embodiments, the second connector 23 of the first type includes two pins; and / or, the second connector 23 of the second type includes three pins.

[0043] In one possible scenario, to adapt to power standards of different countries or regions and meet the electrical safety requirements of equipment, the second connector 23 of the first type can be a two-prong plug 231, such as a two-prong flat connector 2, a double cylindrical connector 2, or a two-prong parallel flat connector. The second connector 23 of the second type can be a three-prong plug 231, such as a three-prong rectangular connector 2 or a three-prong V-shaped connector 2. By setting different second connectors 23 and equipping them with two-prong and three-prong plug 231 connectors respectively, the versatility and safety of the adapter can be enhanced. For example, the two-prong 231 second connector 23 is suitable for low-power devices and portable applications, while the three-prong 231 second connector 23 is suitable for high-power devices and applications requiring grounding protection.

[0044] In some embodiments, the second connection structure 21 includes two elastic portions disposed on opposite side walls of the connector 2 where neither the second plug portion nor the first plug portion is disposed; the first connection structure 104 includes: a slot 1041 disposed on the adapter body 1 for accommodating the connector 2, and the slot 1041 having an opening, and a connection terminal 103 disposed within the slot 1041; a connection portion 1042 disposed on opposite side walls of the slot 1041 and corresponding to the elastic portion 211; wherein, the elastic portion 211 can deform under external force, causing it to elastically abut against or move away from the connection portion 1042, so that the connector 2 switches between a first position and a second position relative to the slot 1041; in the first position, the connector 2 is accommodated in the slot 1041, the second plug portion 23 is exposed in the opening, and the connection terminal 103 is inserted into the first plug portion 22; in the second position, the connector 2 disengages from the slot 1041, and the first plug portion 22 is disconnected from the connection terminal 103.

[0045] In one possible case, such as Figure 1 , Figure 5 , Figure 6As shown, the second connection structure 21 may include two elastic portions 211 disposed opposite to each other on the side walls of the connector 2, and the elastic portions 211 are disposed on the opposite side walls of the connector 2 where neither the second insertion portion 23 nor the first insertion portion 22 is provided. The elastic portions 211 may be made of a material with a certain elasticity (such as spring steel or plastic), capable of deforming under external force and returning to their original shape after the external force is removed. The first connection structure 104 may include a slot 1041, which may be disposed on the top of the adapter body 1 for accommodating the connector 2. The slot 1041 has an opening, allowing the connector 2 to be inserted from the outside. The connection terminal 103 may be disposed in the slot 1041, responsible for electrical connection with the first insertion portion 22 of the connector 2. The connection portions 1042 are disposed opposite to each other on the side walls of the slot 1041, corresponding one-to-one with the elastic portions 211 on the connector 2. The connection portions 1042 may be a pair or more protrusions located on the inner side of the side walls of the slot 1041. These protrusions may have a certain slope or rounded corners to guide the deformation of the elastic part 211 when the connector 2 is inserted. When the connector 2 is inserted, the elastic arm slides along the slope of the protrusion and gradually compresses until the elastic arm completely passes over the protrusion and enters the groove 10422, forming a locked state, such as... Figure 2 As shown. When the user needs to unplug connector 2, press the elastic arm to further deform it, overcoming the locking force with the protrusion, and then gently pull out connector 2 to complete the separation of connector 2 from adapter body 1, as shown. Figure 1 As shown. Alternatively, the elastic part 211 can be a pair of spring clips, installed on the side walls of the connector 2. The connecting part 1042 can be a pair or more locking holes, located on the inner side of the side walls of the slot 1041. These locking holes can be small holes or grooves of a certain depth for receiving the spring clips. When the connector 2 is inserted, the spring clips slide along the inner wall of the slot 1041 until they automatically spring into the locking holes, forming a locked state. When the user needs to remove the connector 2, press the spring clips to disengage them from the locking holes, and then gently pull out the connector 2.

[0046] The cooperation between the first connecting structure 104 and the second connecting structure 21 enables a detachable connection between the connector 2 and the adapter body 1, allowing the connector 2 to switch between a first position and a second position relative to the slot 1041. In the first position, as... Figure 2 , Figure 9 , Figure 13 As shown, the connector 2 is fully inserted into the slot 1041 of the adapter body 1, and the second connector 23 is exposed at the opening of the slot 1041 for connecting to an external power source. The first connector 22 is in close contact with the connection terminal 103 inside the adapter body 1, forming an electrical connection. In the second position, as... Figure 1As shown, the connector 2 detaches from the slot 1041 of the adapter body 1, and the first plug portion 22 disconnects from the connection terminal 103, thus interrupting the electrical connection. With the connector 2 completely detached from the slot 1041, the user can replace it with another type of connector 2 or store it. Through the cooperation of the first connection structure 104 and the second connection structure 21, the connector 2 can achieve a secure and easy-to-operate detachable connection in the slot 1041 of the adapter body 1, improving the adapter's versatility and flexibility, enhancing the user's operating experience, improving the safety and stability of the electrical connection, extending the product's lifespan, and saving costs and resources.

[0047] In some embodiments, the elastic portion 211 includes: spring arms 2111, disposed on opposite sides of the connector 2 along a first direction A, and the spring arms 2111 can move closer to or away from the connector 2 along the first direction A under the action of an external force; each spring arm 2111 has a first engaging portion 2112 on the side facing away from the connector 2, and the first engaging portion 2112 protrudes from the spring arm 2111; each first engaging portion 2112 has a second engaging portion 2113 on the side facing away from the spring arm 2111, and the second engaging portion 2113 protrudes from the first engaging portion 2112; the connecting portion 1042 includes: a slot 10421, which is adapted to the first engaging portion 2112, and the slot 10421 extends to the opening edge of the slot 1041; a groove 10422, disposed in the slot 10421 and forming a stepped groove with the slot 10421, and the groove 10422 abuts against the elastic portion 211 of the second engaging portion 2113.

[0048] In one possible case, such as Figure 5 , Figure 6As shown, the spring arm 2111 can be made of a highly elastic material, such as stainless steel or high-strength plastic. The spring arm 2111 can be flat, with one end fixed to the side wall of the connector 2 and the other end being a free end, allowing it to deform under external force, moving it closer to or away from the connector 2 along the first direction A, thereby providing the necessary elastic deformation. Alternatively, the spring arm 2111 can be U-shaped, with both ends fixed to the side wall of the connector 2 and the middle part being a free end. Each spring arm 2111 has a first engaging portion 2112 on the side facing away from the connector 2. The first engaging portion 2112 protrudes from the surface of the spring arm 2111 and is used to engage with the slot 10421 on the adapter body 1. The slots 10421 are disposed on both side walls of the slot 1041 and are adapted to the first engaging portion 2112. The slots 10421 extend to the edge of the opening of the slot 1041, ensuring that the connector 2 can smoothly guide the spring arm 2111 into the slots 10421 and form a lock during insertion. To enhance the abutment force between the spring arm 211 and the inner wall of the slot 1041, each first engaging portion 2112 has a second engaging portion 2113 on the side opposite to the spring arm 2111. The second engaging portion 2113 protrudes from the surface of the first engaging portion 2112 and can be a protrusion or a stepped structure, used to cooperate with the groove 10422 on the adapter body 1 to provide additional locking force. The groove 10422 is disposed in the slot 10421, forming a stepped groove structure with the slot 10421.

[0049] The user aligns the connector 2 with the opening of the slot 1041 in the adapter body 1 and gently pushes it in. When the connector 2 is inserted, the first engaging portion 2112 on the spring arm 2111 first contacts the entrance of the slot 10421, causing the spring arm 2111 to deform under pressure and retract inwards. As the connector 2 continues to be inserted, the first engaging portion 2112 fully enters the slot 10421 and passes the locking point of the slot 10421, at which point the spring arm 2111 returns to its original shape, forming a preliminary lock. Simultaneously, the second engaging portion 2113 enters the groove 10422 and elastically abuts against it, providing additional locking force to securely fix the connector 2 to the adapter body 1. The first plug portion 22 makes tight contact with the connection terminal 103, completing the electrical connection. When it is necessary to disassemble the connector 2, sliding the connector 2 towards the opening of the slot 1041 will allow the first engaging portion 2112 of the spring arm 2111 to slide out of the slot 10421 and the second engaging portion 2113 to slide out of the groove 10422, thereby removing the connector 2 from the adapter body 1. The engagement of the first engaging portion 2112 with the slot 10421 and the second engaging portion 2113 with the groove 10422 provides a double locking mechanism, enhancing the stability of the connector 2 and preventing loosening due to vibration or accidental impact.

[0050] In some embodiments, the adapter further includes: a sliding inlet 3, wherein a sliding inlet 3 is provided on one side wall of the slot 1041 adjacent to the opening, for the connector 2 to slide into the slot 1041; two sliding grooves 4, which are disposed on opposite side walls of the connector 2 along a first direction A, and extend along the sliding direction of the connector 2; and two sliders 5, which are disposed opposite to each other on the two inner walls of the slot 1041 along the first direction A, and extend along the sliding direction of the connector 2 and correspond one-to-one with and adapt to the sliding grooves 4.

[0051] In one possible case, such as Figure 1 , Figure 3 , Figure 5 As shown, the sliding inlet 3 is located on the side wall of the slot 1041 adjacent to the opening, providing a clearance for the connector 2 to slide into the slot 1041. For example, if the opening of the slot 1041 faces the top of the adapter body 1, then the sliding inlet 3 faces the side of the adapter body 1. Two sliding grooves 4 are disposed opposite each other on the two side walls of the connector 2 along the first direction A. The sliding grooves 4 extend along the direction in which the connector 2 slides in, ensuring that the connector 2 can slide along a predetermined path during insertion. The sliding grooves 4 can be straight or have a certain curvature to match the shape of the sliders 5 and provide a stable guiding function. Two sliders 5 are disposed opposite each other on the two inner walls of the slot 1041 along the first direction A. The sliders 5 extend along the direction in which the connector 2 slides in and correspond one-to-one with the sliding grooves 4. The sliders 5 can be protruding structures that match the sliding grooves 4, allowing them to slide smoothly within the sliding grooves 4 and providing a precise guiding function. The user aligns the connector 2 with the sliding inlet 3 on the adapter body 1 and gently pushes it in. When the connector 2 begins to slide in, the grooves 4 on both sides of the connector 2 contact the slider 5 in the slot 1041. The slider 5 enters the groove 4, providing a precise guiding function so that the connector 2 can be accurately aligned and smoothly slide into the slot 1041.

[0052] In some embodiments, the starting end of the slider 5 is provided with a guide surface 51 that forms an obtuse angle with the inner wall of the slot 1041; and / or, the width of the starting segment of the groove 4 increases in the direction from the end to the starting end.

[0053] In one possible case, such as Figure 5 As shown, the starting end of the slider 5 can be a guide surface 51 forming an obtuse angle with the inner wall of the slot 1041. This angle can be between 90° and 135°, and the specific angle can be adjusted according to actual needs. Figure 1As shown, the width of the initial section of the groove 4 gradually increases from the end to the beginning, forming a shape similar to a trumpet. The guide surface 51 of the slider 5 provides initial guidance for the connector 2, allowing it to slide along a predetermined path. The increasing width of the groove 4 further expands the entrance space, ensuring that the slider 5 can smoothly enter the groove 4. Even if the angle of the connector 2 deviates slightly, the guide surface 51 and the increasing width setting can automatically correct the path, ensuring that the connector 2 slides smoothly into the slot 1041.

[0054] In some embodiments, the second connection structure 21 is an annular insertion groove 212, and the annular insertion groove 212 extends outward to form a limiting edge 213, the limiting edge 213 having a notch 214; the second insertion portion 23 is exposed on the insertion surface 24 of the plug 2, and the first insertion portion 22 is exposed on the inner ring of the annular insertion groove 212; the first connection structure 104 is a boss 1043 protruding from the adapter body, the outer peripheral edge of the boss 1043 having a buckle 1044 extending outward and adapted to the notch 214, the connection terminal 103 being disposed on the boss 1043 and corresponding to the first insertion portion 22; wherein, the annular insertion groove 212 and the boss 1043 are rotatably engaged to lock or disengage the plug 2 from the adapter body 1.

[0055] In one possible case, such as Figure 10 , Figure 11 , Figure 12 As shown, the annular insertion groove 212 is located on one side of the connector 2 and is circular or annular in shape. The annular insertion groove 212 extends outward to form a limiting edge 213, which limits the insertion depth of the connector 2 and provides additional mechanical fixation. The limiting edge 213 has one or more notches 214 for engaging with the latches 1044 on the adapter body 1 to achieve locking and unlocking functions. The first insertion part 22 is exposed in the inner ring of the annular insertion groove 212 and is used to establish an electrical connection with the connection terminal 103 in the adapter body 1. The first connection structure 104 is a boss 1043 protruding from the adapter body 1, which is circular or annular in shape and matches the annular insertion groove 212 of the connector 2. The outer peripheral edge of the boss 1043 has latches 1044 extending outward, which are adapted to the notches 214 on the annular insertion groove 212 to achieve locking and unlocking functions. The connecting terminal 103 is disposed on the boss 1043 and corresponds to the first plug portion 22 of the plug 2.

[0056] like Figure 14As shown, the connector 2 may include a socket front cover 6, an adapter metal terminal group 7, a rotating retaining ring 8, a fixed support 9, and a rotating base 10. The socket front cover 6 is a protective outer shell with a receiving cavity, the shape of which can be customized according to actual needs. The adapter metal terminal group 7 is located within the receiving cavity of the socket front cover 6 and fixed within the rotating retaining ring 8. The rotating retaining ring 8 may be annular, providing mechanical support and rotational function. The rotating retaining ring 8 has an annular insertion groove 212, forming a limiting edge 213, and a notch 214. The fixed support 9 is located below the rotating retaining ring 8, providing support for the overall structure. Located at the bottom of the entire connector 2, it provides stability and a connection point for the overall structure. The rotating base 10 is connected to the fixed support 9, ensuring the stability of the overall structure.

[0057] The user aligns the connector 2 with the boss 1043 on the adapter body 1 and gently pushes it in. The annular groove 212 fits onto the boss 1043, ensuring a tight fit. When the connector 2 is fully inserted, the notch 214 of the annular groove 212 aligns with the latch 1044 on the boss 1043. Rotating the connector 2 causes the latch 1044 to disengage from the notch 214, allowing the latch 1044 to engage with the interior of the annular groove 212, forming a mechanical lock. At this point, the first connector 22 is in close contact with the connection terminal 103, completing the electrical connection. The user can release the lock by rotating the connector 2 in the opposite direction, realigning the notch 214 of the annular groove 212 with the latch 1044 on the boss 1043, and pulling the connector 2 outward. The engagement of the annular insertion groove 212 and the boss 1043, along with the locking mechanism of the notch 214 and the latch 1044, provides a dual locking effect, enhancing the stability of the connector 2 and preventing loosening due to vibration or accidental collisions. Furthermore, users can complete the locking and unlocking operations simply by aligning, inserting, and rotating, without requiring complex tools or steps, thus improving operational convenience.

[0058] In some embodiments, each pin 231 of the second connector 23 includes an adapter terminal and a socket terminal, wherein the socket terminal is detachably connected to the adapter terminal.

[0059] In one possible case, such as Figure 15As shown, the adapter terminal is used to transmit current from an external power source to the adapter body 1. The socket terminal is the exposed part of the pin 231, which is directly inserted into an external power socket (such as a wall socket or extension cord socket) and detachably connected to the adapter terminal. The adapter terminal can be made of a highly conductive material (such as copper or nickel-plated copper). The socket terminal is detachably connected to the adapter terminal through a standardized interface, allowing users to replace different types of socket terminals as needed to adapt to different power standards. For example, the plug 2 is a circular three-prong plug 2, which includes three pins 231, namely the pin 231 formed by the socket live wire terminal 11 and the live wire adapter terminal 12, the pin 231 formed by the socket neutral wire terminal 13 and the neutral wire adapter terminal 14, and the pin 231 formed by the socket ground wire terminal 15 and the ground wire adapter terminal 16. By setting the pin 231 as a modular structure consisting of an adapter terminal (first plug-in part 22) and a socket terminal (second plug-in part 23) and adopting a detachable connection method, the versatility and flexibility of the adapter are improved.
