Description

Adapter socket

[0001] This application claims priority to Chinese Patent Application No. 202411999120.7, filed on December 31, 2024, entitled "Converter Socket", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electrical equipment technology, and more specifically, to a converter socket. Background Technology

[0003] Because of the differences in adapter sockets between countries, and the different charger or plug standards in each country, adapter sockets that integrate plugs from major countries around the world have emerged to meet the needs of global business, travel abroad, and study abroad.

[0004] However, when using one plug in an existing adapter socket, the other plugs are electrically connected to the electrical connection components and are in a energized state. This can cause electric shock when the user touches the other plugs, and the other plugs are prone to sparking and breaking down inside the adapter socket, causing the adapter socket to heat up, or even causing a fire, posing a safety hazard. Summary of the Invention

[0005] This application provides a converter socket designed to disconnect the electrical connection between a plug in a retracted state and an electrical connection component via a rocker assembly, thereby placing the plug in a power-off state and improving the safety of the converter socket.

[0006] This application provides a converter socket, which includes a housing, a first plug, at least one rocker assembly, and an electrical connection assembly. The electrical connection assembly is disposed within the housing. The rocker assembly is disposed within the housing and includes a rocker that can rotate relative to the housing. The first plug includes at least two first prongs rotatably mounted on the housing. At least one first prong slides against a rocker for electrical connection. During rotation of the first prong, the first prong has a state that drives the rocker to rotate to an upright state that is electrically connected to the electrical connection assembly, and a state that drives the rocker to rotate to a retracted state that is electrically disconnected from the electrical connection assembly. The second plug is mounted on the housing, and the second prong has at least a usage state that is connected to mains power and electrically connected to the electrical connection assembly. When the second plug is in the usage state, the first plug switches to the retracted state.

[0007] Based on the adapter socket of this application, when the second plug is in use, the first plug is switched to the retracted state, and the first prong is disconnected from the electrical connection component via a rocker arm, thereby preventing electric shock when the user touches the first prong and improving the safety of the adapter socket. Simultaneously, when the first plug is switched to the upright state, the first prong is electrically connected to the electrical connection component via the rocker arm, allowing the user to connect the first plug to mains power to use the adapter socket.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please refer to Figures 1 and 2 together. This application embodiment provides a conversion socket 1, which includes a housing 11, a first plug 12, at least one rocker assembly 13, an electrical connection assembly 14, and a second plug 17.

[0026] It should be noted that the housing 11 has a plug interface 114, into which external devices can extend and connect to the electrical connection assembly 14. The plug interface 114 can be a socket or a USB port; no specific limitation is made here. The first plug 12 has many specifications; it can be a European plug, an American plug, or a British plug; no specific limitation is made here.

[0027] Please refer to Figure 2. The first plug 12 includes at least two first prongs 121 rotatably mounted on the housing 11. At least one first prong 121 slides against a rocker 131 for electrical connection. During the rotation of the first prong 12, the first prong 12 has the ability to drive the rocker 131 to rotate to an upright state that is electrically connected to the electrical connection assembly 14, and to drive the rocker 131 to rotate to a retracted state that is electrically disconnected from the electrical connection assembly 14.

[0028] The first plug 12 is configured to connect to an external socket for access to mains power. When the first plug 121 is in the upright state, the first plug 121 needs to partially extend out of the housing 11 so that the first plug 121 can connect to the external socket. When the first plug 121 is in the retracted state, the first plug 121 can be laid flat on the surface of the housing 11 or can be housed inside the housing 11. No specific limitation is made here.

[0029] Preferably, referring to Figure 2, the housing 11 is provided with a receiving groove 115, and the first plug 121 is located in the receiving groove 115. When the first plug 121 is in the upright state, one end of the first plug 121 extends out of the groove opening of the receiving groove 115. When the first plug 121 is in the retracted state, the first plug 121 is completely contained in the receiving groove 115, so that the housing 11 can protect the first plug 121, and at the same time reduce the size of the adapter 1, making it easier for the user to store.

[0030] The second plug 17 is installed on the housing 11. The second plug 17 includes at least a use state in which it is connected to the mains power and electrically connected to the electrical connection component 14. When the second plug 17 is in the use state, the first plug 12 is switched to the storage state.

[0031] Please refer to Figures 3 and 4. The rocker assembly 13 is disposed within the housing 11. The rocker assembly 13 includes a rocker 131 that can rotate relative to the housing 11. At least one first pin 121 slides against the rocker 131 to achieve an electrical connection between them. The first pin 121 is electrically connected to the electrical connection assembly 14 through the rocker 131. The rocker 131 needs to be made of a conductive material, such as copper, aluminum, or graphite. There are many ways for the rocker 131 to rotate relative to the housing 11. The rocker 131 can be rotatably connected to the housing 11 via a pivot, or the rocker 131 can be rotated around the support 132 by a support member 132 that abuts against the middle of the rocker 131. No specific limitation is made here.

[0032] There are many ways in which the first plug 12 and the rocker assembly 13 can be coupled. One of the two first pins 121 can slide against the rocker 131. When the first plug 12 is in the retracted state, the electrical connection between one of the first pins 121 and the electrical connection assembly 14 can be disconnected so that the two first pins 121 cannot form a circuit with the electrical connection assembly 14, thereby disconnecting the electrical connection between the first plug 12 and the electrical connection assembly 14. Alternatively, the two first pins 121 can slide against the two rockers 131 respectively. When the first plug 12 is in the retracted state, both first pins 121 can be disconnected from the electrical connection assembly 14, thereby disconnecting the first plug 12 from the electrical connection assembly 14. No specific limitation is made here.

[0033] The electrical connection assembly 14 is disposed inside the housing 11. When the first pin 121 switches from the retracted state to the upright state, the first pin 121 drives the rocker arm 131 to rotate until it contacts the electrical connection assembly 14, so that the electrical connection assembly 14 is electrically connected to the first pin 121. When the first pin 121 switches from the upright state to the retracted state, the first pin 121 drives the rocker arm 131 to rotate until it separates from the electrical connection assembly 14, so that the electrical connection assembly 14 is disconnected from the first pin 121.

[0034] There are many ways in which the first pin 121 drives the rocker 131 to rotate. For example, one end of the rocker 131 is rotatably mounted on the housing 11, and the other end of the rocker 131 is connected to the first pin 121, so that the rocker 131 has a rotating end and an abutting end. The first pin 121 can slide on the abutting end to drive the abutting end to rotate around the rotating end. When the first pin 121 is in the upright state, the abutting end abuts against the electrical connection component 14. When the first pin 121 is in the retracted state, the abutting end is disconnected from the electrical connection component 14.

[0035] For example, the rocker 131 is rotatably mounted on the housing 11 at its center. The rocker 131 has two abutting ends located on both sides of its own rotation axis. The rocker 131 can slide on one of its abutting ends to drive the other abutting end to move. When the first pin 121 is in the upright state, the other abutting end abuts against the electrical connection assembly 14. When the first pin 121 is in the retracted state, the other abutting end is disconnected from the electrical connection assembly 14.

[0036] For example, the rocker arm 131 is rotatably mounted on the housing 11 at its center. The rocker arm 131 has a first abutment end and a second abutment end located on both sides of its rotation axis. The rocker arm 131 can slide on the first abutment end and the second abutment end. When the first pin 121 is in the upright state, the first pin 121 abuts against the first abutment end, and the first abutment end abuts against the electrical connection assembly 14. When the first pin 121 is in the retracted state, the first pin 121 abuts against the second abutment end, and the first abutment end is disconnected from the electrical connection assembly 14. Further examples are not listed here.

[0037] Based on the adapter socket 1 of this application, when the second plug 17 is in use, the first plug 12 is switched to the retracted state. The first plug 12 is disconnected from the electrical connection assembly 14 via the rocker arm 131, thereby preventing electric shock when the user touches the first prong 121 and improving the safety of the adapter socket 1. Simultaneously, when the first plug 12 is switched to the upright state, the first prong 121 is electrically connected to the electrical connection assembly 14 via the rocker arm 131, allowing the user to connect the first plug 12 to mains power to use the adapter socket 1.

[0038] Please refer to Figures 3 and 4 together. In some embodiments of this application, the rocker assembly 13 further includes a support member 132. The support member 132 is disposed within the housing 11 and abuts against the surface of the rocker 131 opposite to the first pin 121, so that the rocker 131 can rotate around the support member 132. With this arrangement, the support member 132 and the first pin 121 are respectively disposed on both sides of the rocker 131, so as to avoid interference between the first pin 121 and the support member 132 when the first pin 121 rotates. At the same time, it makes full use of the space of the rocker 131 in the direction of approaching or away from the first pin 121.

[0039] Further, referring to Figure 5, the rocker 131 includes a contact segment 1311, which is located at one end of the rocker 131 in its extending direction and is spaced apart from the support member 132. When the first plug 121 is in the retracted state, the contact segment 1311 is separated from the electrical connection assembly 14; when the first plug 121 is in the upright state, the contact segment 1311 is in contact with the electrical connection assembly 14. This configuration allows the contact segment 1311 to have a large range of rotation, thus ensuring that the contact segment 1311 is separated from the electrical connection assembly 14 when the first plug 121 is in the retracted state and that the contact segment 1311 abuts against the electrical connection assembly 14 when the first plug 121 is in the upright state.

[0040] It should be noted that, please refer to Figures 3 and 4 as well. The rocker assembly 13 also includes an electrical connector 134. The electrical connector 134 is installed on the contact section 1311. The contact section 1311 abuts against and is electrically connected to the electrical connection assembly 14 through the electrical connector 134. This arrangement can reduce the collision between the contact section 1311 and the electrical connection assembly 14, thereby reducing the wear on the rocker 131. At the same time, when the electrical connector 134 is damaged, only the electrical connector 134 needs to be replaced, so there is no need to replace the entire rocker 131, thereby reducing the maintenance cost of the rocker assembly 13 in the later stage.

[0041] In some embodiments of this application, referring to FIG5, the rocker 131 further includes a first abutting section 1312 and abutting section 1314, the first abutting section 1312 and the second abutting section 1314 being located on both sides of the support member 132 respectively, and the end of the first abutting section 1312 away from the second abutting section 1314 being connected to the contact section 1311; when the first pin 121 is in the retracted state, the first pin 121 abuts against the second abutting section 1314, and the contact section 1311 is separated from the electrical connection assembly 14, so that the electrical connection assembly 14 is disconnected from the first pin 121; when the first pin 121 is in the retracted state, the first pin 121 abuts against the first abutting section 1312, and the contact section 1311 contacts the electrical connection assembly 14, so that the electrical connection assembly 14 is electrically connected to the first pin 121.

[0042] With this configuration, when the first pin 121 is in the upright position, it abuts against the first abutment section 1312. The first abutment section 1312 and the contact section 1311 are located on the same side of the support member 132, thus allowing the first pin 121 to be configured as the side of the rocker arm 131 with the contact section 1311, ensuring that the contact section 1311 can stably abut against the electrical connection assembly 14. When the first pin 121 is in the retracted position, it abuts against the second abutment section 1314. The second abutment section 1314 and the contact section 1311 are located on opposite sides of the support member 132, thus allowing the first pin 121 to be configured as the side of the rocker arm 131 away from the contact section 1311, ensuring that the contact section 1311 is separated from the electrical connection assembly 14. Simultaneously, the contact section 1311 has a large range of rotation.

[0043] As can be understood, referring to Figure 5, the rocker 131 has a contact section 1311, a first abutment section 1312, a support section 1313, and a second abutment section 1314 connected in sequence, with the support member 132 abutting against the support section 1313. When the first prong 121 switches from the retracted state to the upright state, the first prong 121 starts from the second abutment section 1314, passes through the support section 1313, and then abuts against the first abutment section 1312. When the first prong 121 switches from the upright state to the retracted state, the first prong 121 starts from the first abutment section 1312, passes through the support section 1313, and then abuts against the second abutment section 1314.

[0044] Further, referring to Figure 5, a limiting groove 1315 is provided on the surface of the rocker 131 away from the support member 132. The two groove walls of the limiting groove 1315 in the extension direction of the rocker 131 are located at the first abutting section 1312 and the second abutting section 1314, respectively. When the first plug 12 is in the retracted state, the first pin 121 abuts against the groove wall of the limiting groove 1315 located at the second abutting section 1314; when the first plug 12 is in the upright state, the first pin 121 abuts against the groove wall of the limiting groove 1315 located at the first abutting section 1312.

[0045] With this configuration, the limiting groove 1315 can cooperate with the first pin 121 to prevent the first pin 121 from being misaligned with the rocker 131 during the rotation of the first plug 12.

[0046] Please refer to Figures 3 and 4 together. In some embodiments of this application, the rocker assembly 13 further includes an elastic element 133. One end of the elastic element 133 is connected to the support member 132, and the other end of the elastic element 133 is connected to the housing 11. The elastic element 133 is configured to drive the support member 132 to move toward the rocker 131. With this configuration, during the rotation of the first plug 12, the elastic element 133 drives the support element 132 to float, thereby reducing the rigid wear between the rocker arm 131 and the support element 132, and thus improving the service life of the first plug 12 and the rocker arm 131. At the same time, the elastic element 133 applies an elastic force to the support element 132 in the direction of the rocker arm 131. When the first pin 121 abuts against the first contact section 1312 or the second contact section 1314, the support section 1313 will move towards the pin under the drive of the support element 132, thereby restricting the drive unit 18 to the first contact section 1312 or the second contact section 1314. This allows the first plug 12 to be stably positioned in the upright or retracted state, preventing the first pin 121 from rotating when the adapter socket 1 is shaken, thus affecting the user's use.

[0047] It should be noted that there are many types of elastic elements 133. Elastic element 133 can be a spring or an elastic body, and no specific limitation is made here.

[0048] Furthermore, please refer to Figures 3 and 4. The housing 11 is recessed with a mounting groove 111, and the surface of the support member 132 away from the rocker arm 131 is recessed with an abutment groove 1321. Part of the support member 132 extends into the mounting groove 111. One end of the elastic member 133 is connected to the bottom of the mounting groove 111, and the other end of the elastic member 133 is connected to the bottom of the abutment groove 1321. This arrangement guides the elastic member 133 through the mounting groove 111, preventing the support member 132 from moving along the extension direction of the rocker arm 131 under the drive of the elastic member 133, thus preventing the support member 132 from detaching from the support section 1313. Simultaneously, the abutment groove 1321 on the support member 132, by extending one end of the elastic member 133 into the abutment groove 1321, prevents misalignment between the support member 132 and the elastic member 133 during movement, thus preventing the elastic member 133 from detaching from the support member 132.

[0049] Please refer to Figures 5 and 6. In some embodiments of this application, the housing 11 is further provided with a movable groove 112. Limiting grooves 113 are provided on the two groove walls of the movable groove 112 along the rotational axis of the rocker 131. The limiting grooves 113 extend in a direction close to or away from the corresponding first pin 121. The rocker 131 is located within the movable groove 112. Limiting portions 1316 protrude from both ends of the supporting section 1313 of the rocker 131 along its own rotational axis, and the limiting portions 1316 extend into the corresponding limiting grooves 113. This arrangement ensures that the rocker 131 moves in a direction close to or away from the corresponding first pin 121 through the cooperation of the limiting portions 1316 and the limiting grooves 113, preventing the rocker 131 from moving along its own extension direction and causing misalignment between the rocker 131 and the abutment section.

[0050] It should be noted that the bottom of the movable groove 112 is recessed with an installation groove 111, and the support member 132 is located inside the movable groove 112.

[0051] In some embodiments of this application, please refer to Figures 2, 7 to 9. The rotation axes of the two first pins 121 are arranged parallel to each other. The free ends of the two first plugs 12 move away from each other to switch from an upright state to a retracted state, and the free ends of the two first plugs 12 move towards each other to switch from a retracted state to an upright state. With this arrangement, when the two first pins 121 are in the retracted state, the free ends of the two first pins 121 extend in a direction away from each other, and when the two first pins 121 are in the upright state, the free ends of the two first pins 121 extend in a direction parallel to each other.

[0052] In some embodiments of this application, please refer to Figures 7 to 9 together. The adapter socket 1 further includes a rack 15 and two gears 16. The rack 15 is slidably mounted on the housing 11 and can move towards or away from each other along the free ends of the two first pins 121. The rack 15 is provided with an upper tooth 151 and a lower tooth 152. The two gears 16 are installed one-to-one with the two first pins 121. The two gears 16 mesh with the upper tooth 151 and the lower tooth 152 respectively, so that the rotation directions of the two first pins 121 are opposite and the two pins rotate synchronously. It can be understood that the rotation axis of the gear 16 is collinear with the rotation axis of the corresponding pin.

[0053] With this configuration, only one pin needs to be driven to rotate, which drives the corresponding gear 16 to rotate. The corresponding gear 16 engages with the upper tooth 151 to drive the rack 15 to move. The rack 15 engages with the other gear 16 through the lower tooth 152, thereby driving the other pin to rotate. Thus, only one pin needs to be rotated to drive the other pin to rotate, which makes it convenient for the user to switch the first plug 12 between the upright state and the retracted state.

[0054] Further, referring to Figures 7 to 9, the second plug 17 is slidably mounted on the housing 11 to have an upright state and a retracted state; the adapter socket 1 also includes a drive unit 18 and a blocking member 19. The drive unit 18 is connected to the second plug 17 and partially exposed outside the housing 11 to drive the second plug 17 to switch between the upright state and the retracted state; the blocking member 19 is movably mounted on the housing 11 and can abut against the rack 15 and the drive unit 18; when the first pin 121 switches from the retracted state to the upright state, the rack 15 drives the blocking member 19 to move, so that the blocking member 19 blocks the drive unit 18 to lock the second plug 17 in the retracted state; when the second plug 17 switches from the retracted state to the upright state, the drive unit 18 drives the blocking member 19 to move, so that the blocking member 19 blocks the rack 15 to lock the first pin 121 in the retracted state. It should be noted that the blocking member 19 blocks the drive unit 18 by extending part of it into the movement path of the drive unit 18, and the blocking member 19 blocks the rack 15 by extending part of it into the movement path of the rack 15.

[0055] With this configuration, when the first plug 12 is in the upright position, the drive unit 18 of the second plug 17 is limited by the blocking member 19, preventing it from extending out of the housing 11. When the second plug 17 is in the upright position, the rack 15 is also limited by the blocking member 19, preventing the first plug 12 from switching to the upright position. This avoids the first plug 12 and the second plug 17 being in the upright position simultaneously, and prevents the second plug 17 from extending out of the housing 11 when the first plug 12 is in the upright position and energized, thus avoiding potential contact with the second plug 17 and electric shock, thereby improving the safety of the adapter socket 1. Simultaneously, the user can drive the second plug 17 to move via the drive unit 18, making it easier for the user to use.

[0056] It should be noted that the second plug 17 includes at least two second prongs 171. The second prongs 171 are slidably mounted on the housing 11. When the second plug 17 is in the upright state, the second prongs 171 extend out of the housing 11 so that the second plug 17 can be connected to an external socket to access the mains power, thereby switching to the use state. When the second plug 17 is in the retracted state, the second prongs 171 are housed inside the housing 11.

[0057] There are many ways in which the blocking member 19 can be movably installed on the housing 11. The blocking member 19 can be slidably installed on the housing 11 or rotatedly installed on the housing 11. No specific limitation is made.

[0058] When the blocking member 19 is slidably mounted on the housing 11, the blocking member 19 can move in directions where the driving part 18 and the rack 15 approach or move away from each other. There are many ways in which the driving part 18 drives the blocking member 19 to slide. For example, the blocking member 19 may be provided with a driving channel, which is inclined from the direction near the driving part 18 towards the direction near the rack 15. The driving part 18 is at least partially located within the driving channel, and the driving part 18 drives the blocking member 19 to move by cooperating with the channel wall of the driving channel. Another example is that the outer peripheral wall of the blocking member 19 may be provided with a ramp, which is inclined from the direction near the driving part 18 towards the direction near the rack 15. The driving part 18 drives the blocking member 19 to move by cooperating with the ramp. These are just a few examples.

[0059] When the blocking member 19 is rotatably mounted on the housing 11, the rotation axis of the blocking member 19 is located between the rack 15 and the blocking member 19, and the rotation axis of the blocking member 19 is parallel to the sliding direction of the second plug 17. The blocking member 19 has a first blocking end and a second blocking end. When the second plug 17 switches from the retracted state to the upright state, the second plug 17 drives the first blocking end to move, causing the second blocking end to move towards the rack 15. The second blocking end is located on the movement path of the rack 15 to lock the first pin 121 in the retracted state. When the first plug 12 switches from the retracted state to the upright state, the rack 15 drives the second blocking end to move, causing the first blocking end to move towards the second plug 17. The second blocking end is located on the movement path of the drive unit 18 to lock the second plug 17 in the retracted state.

[0060] In some embodiments of this application, please refer to Figures 2 and 10 together. The adapter socket 1 also includes a third plug 1a and at least two electrical connectors 1b.

[0061] The third plug 1a includes at least two third pins 11a, which are rotatably mounted on the housing 11 to have an upright state and a retracted state. The third plug 1a has many specifications; it can be a European standard plug, an American standard plug, or a British standard plug, without any specific limitation here.

[0062] Each connector 1b is connected to a third pin 11a in a one-to-one correspondence. Each connector 1b is provided with a rocker assembly 13. When the third pin 11a switches from the retracted state to the upright state, the third pin 11a drives the connector 1b to rotate, and the connector 1b drives the corresponding rocker 131 to rotate until it contacts the electrical connection assembly 14. When the third pin 11a switches from the upright state to the retracted state, the third pin 11a drives the connector 1b to rotate, and the connector 1b drives the corresponding rocker 131 to rotate until it separates from the electrical connection assembly 14.

[0063] This configuration improves the practicality of the adapter socket 1 by providing a third plug 1a. At the same time, the third pin 11a can be powered on and off by the connecting part 1b and the corresponding rocker assembly 13, thereby improving the safety of the adapter socket 1.

[0064] In some embodiments of this application, the connector 1b includes a connecting portion 11b and an abutting portion 12b. One end of the connecting portion 11b is connected to the corresponding third pin 11a, and the other end of the connecting portion 11b extends along the rotational axis of the corresponding third pin 11a and connects to the abutting portion 12b. The abutting portion 12b extends radially along the connecting portion 11b, and the connecting portion 11b can drive the abutting portion 12b to rotate about the rotational axis of the third pin 1a. It is understood that the axial direction of the connecting portion 11b is collinear with the rotational axis of the third pin 11a.

[0065] When the abutment part 12b abuts against the corresponding rocker arm 131, and the third pin 11a switches from the retracted state to the upright state, the third pin 11a drives the abutment part 12b to rotate, and the abutment part 12b drives the corresponding rocker arm 131 to rotate until it contacts the electrical connection assembly 14; when the third pin 11a switches from the upright state to the retracted state, the third pin 11a drives the abutment part 12b to rotate, and the abutment part 12b drives the corresponding rocker arm 131 to rotate until it separates from the electrical connection assembly 14.

[0066] With this configuration, the third pin 11a slides against the corresponding rocker arm 131 via the abutment portion 12b, allowing the rocker arm 131 to be positioned on both sides of the third pin 1a along its rotational axis, thus fully utilizing the space of the rocker arm 131 along its rotational axis. The connecting portion 11b extends along the rotational axis of the third pin 11a. By providing the abutment portion 12b at the end of the connecting portion 11b away from the third pin 11a, which slides against the rocker arm 131, interference between the third pin 11a and the rocker arm assembly 13 can be avoided when the third pin 11a rotates.

[0067] Please refer to Figure 2. In some embodiments of this application, the rocker assembly 13 is configured to correspond one-to-one with the first pin 121 and the third pin 11a. It can be understood that each first pin 121 and each third pin 11a is provided with a rocker assembly 13. This configuration ensures that when the first plug 12 and the second plug 17 are in the retracted state, the first pin 121 and the third pin 11a are disconnected from the electrical connection assembly 14 through the rocker assembly 13, thereby improving the safety of the adapter socket 1.

[0068] In some embodiments of this application, the first plug 12 is a US standard plug, the second plug 17 is a UK standard plug, and the third plug 1a is a European standard plug. With this arrangement, since the prongs of the European standard plug are longer, arranging them with the same rotation axis can reduce the space occupied by the European standard plug in the width direction of the housing 11. On the other hand, the prongs of the US standard plug are shorter, and arranging the rotation axes of the two prongs of the US standard plug in parallel can reduce the space occupied by the US standard plug in the length direction of the housing 11, thereby reducing the volume of the housing 11.

[0069] Please refer to Figure 1. In some embodiments of this application, the first plug 12, the second plug 17, and the third plug 1a, all in the upright position, extend from the same surface of the housing 11. With this configuration, when the first plug 12 and the second plug 17 are both in the upright position, the first plug 12 connects to the external socket, and the second plug 17 interferes with the external socket, thereby preventing the first plug 12 from connecting to the external circuit. Thus, the adapter socket 1 can only connect to the external socket when one of the first plug 12, the second plug 17, and the third plug 1a is in the upright position, thereby ensuring the safety of the adapter socket 1.

[0070] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
