Description

[0001] Adapter socket Technical Field

[0002] This utility model relates to a conversion socket, and more particularly to a conversion socket with high safety. Background Technology

[0003] A power adapter is a device that converts a plug of one type to another, facilitating international use for residents of different countries. Currently, there are six common plug standards: Chinese, American, European, British, Australian, and South African. Power adapters typically incorporate at least three of these standards. Existing power adapters usually use a sliding, retractable plug mechanism for conversion; when needed, the corresponding plug is extended out of the casing, and when not in use, it is pushed back in. However, existing power adapters lack safety locks for each plug. When using one plug, accidental extension of another could energize it, posing a significant safety hazard and the risk of electric shock. Utility Model Content

[0004] The purpose of this invention is to provide a convenient and safe adapter socket.

[0005] To achieve the above objectives, this utility model provides a conversion socket, including a housing, a first pin assembly, a second pin assembly, and a first baffle. The housing has a first sliding groove and a second sliding groove. The first pin assembly is slidably disposed within the housing, and the operating handle of the first pin assembly extends out of the first sliding groove and slides along the first sliding groove. The second pin assembly is slidably disposed within the housing, and the operating handle of the second pin assembly extends out of the second sliding groove and slides along the second sliding groove. The first baffle is slidably disposed within the housing and located between the first pin assembly and the second pin assembly to prevent one of the first pin assembly and the second pin assembly from sliding within their respective sliding grooves, and to release the other of the first pin assembly and the second pin assembly.

[0006] Compared with the prior art, this utility model slidably sets a first baffle on the housing, positioning it between the first and second pin components. This allows the first baffle to block one of the first and second pin components while releasing the other. Therefore, when one of the first and second pin components extends out of the housing and is in use, its operating handle can prevent the first baffle from moving. This forces the first baffle to block the groove of the other pin component, preventing it from entering the groove and thus preventing it from extending out of the housing. This effectively avoids electric shock accidents caused by unused pin components accidentally extending, improving safety. Furthermore, the first baffle moves automatically when the pin component extends, requiring no manual operation and providing automatic forced protection, ensuring both safety and convenience.

[0007] Preferably, the adapter further includes a third prong assembly and a second stop. The third prong assembly is movably disposed within the housing, and the second stop is slidably disposed within the housing and located between the second and third prong assemblies to prevent one of the two prong assemblies from moving while releasing the other. By providing the second stop, which can cooperate with the first stop, when one prong assembly extends outside the housing, the two stops can block the other two prong assemblies, thus allowing only one prong assembly to extend, thereby ensuring the safety of using multi-prong adapters.

[0008] Specifically, the adapter socket further includes a third baffle, the third pin assembly is rotatably mounted on the housing via a rotating shaft, and one end of the rotating shaft is provided with a swing portion. The third baffle is rotatably mounted on the housing so that when the second baffle releases the second pin assembly, it together with the second baffle clamps the swing portion.

[0009] Specifically, the third baffle extends into a pushing portion, which extends toward the second baffle and abuts against the second baffle when the second baffle clamps the swinging portion. When the third pin assembly rotates and extends out of the housing, the swinging portion pushes the third baffle, causing the pushing portion to push the second baffle to a position that prevents the second pin assembly from sliding in the second groove. Since the third pin assembly is rotatably arranged, by rotatably arranging the third baffle, the third baffle and the second baffle can clamp the swinging portion together, achieving the purpose of preventing the third pin assembly from extending. Furthermore, by extending the third baffle into a pushing portion, the pushing portion drives the second baffle, causing the second baffle and the third baffle to move away from each other. Thus, when the third pin assembly rotates and extends, the pushing portion pushes the second baffle and the third baffle away from each other, thereby achieving the purpose of releasing the third pin assembly.

[0010] Specifically, the first baffle has an inclined first pushing surface on the side near the operating handle of the first pin assembly, so as to push the first baffle away from the first slide groove when the first pin assembly slides into the first slide groove; the first baffle has an inclined second pushing surface on the side near the operating handle of the second pin assembly, so as to push the first baffle away from the second slide groove when the second pin assembly slides into the second slide groove; the second baffle has an inclined third pushing surface on the side near the operating handle of the second pin assembly, so as to push the second baffle away from the second slide groove when the second pin assembly slides into the second slide groove. By setting the first, second, and third pushing surfaces, the first and second baffles can automatically slide to the other side under the drive of the operating handle of the first or second pin assembly, thereby automatically blocking other pin assemblies and improving the convenience of operation.

[0011] Specifically, the adapter also includes an upper connection terminal and a lower connection terminal, which are arranged vertically within the housing and electrically connected to each other. When the first pin assembly, the second pin assembly, or the third pin assembly 7 extends out of the housing, it is electrically connected to the lower connection terminal.

[0012] Preferably, the width of the first baffle is equal to the distance between the center lines of the first and second slide grooves, and the sliding stroke of the first baffle is equal to the width of the first slide groove. This ensures that when one of the first and second pin assemblies extends, the other is blocked by the first baffle, eliminating the need for manual operation and improving ease of use.

[0020] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] Please see Figures 1 to 4The adapter socket 100 of this utility model includes a housing 1, a first pin assembly 2, a second pin assembly 3, a first baffle 4, an upper connecting terminal 5, and a lower connecting terminal 6. The upper connecting terminal 5 and the lower connecting terminal 6 are arranged vertically within the housing 1 and are electrically connected to each other. The first pin assembly 2 and the second pin assembly 3 are slidably disposed within the housing 1. When the first pin assembly 2 and the second pin assembly 3 extend out of the housing 1, they are electrically connected to the lower connecting terminal 6. The upper side of the housing 1 has several sockets (not shown) to facilitate the connection of the plug of an electrical device to the upper connecting terminal 5 through the sockets. The lower side of the housing 1 has several through holes 13, each corresponding to a pin of the first pin assembly 2 and the second pin assembly 3, to facilitate the extension of each pin out of the housing 1. One side wall of the housing 1 has a first sliding groove 11 and a second sliding groove 12, the extending direction of the first sliding groove 11 being in the same direction as the sliding direction of the first pin assembly. The first slide groove 11 is parallel to the second slide groove 12. The operating handle 21 of the first pin assembly 2 extends out of the first slide groove 11 and slides along it. The operating handle 31 of the second pin assembly 3 extends out of the second slide groove 12 and slides along it. The first baffle 4 is slidably disposed on one side of the housing 1 and located between the first pin assembly 2 and the second pin assembly 3 to prevent one of the first pin assembly 2 and the second pin assembly 3 from sliding within their respective slide grooves, and to release the other of the first pin assembly 2 and the second pin assembly 3. The sliding direction of the first baffle 4 is perpendicular to the sliding direction of the first pin assembly 2. The width of the first baffle 4 is equal to the distance between the center line of the first slide groove 11 and the center line of the second slide groove 12, and the sliding stroke of the first baffle 4 is equal to the width of the first slide groove 11. The width of the first slide groove 11 is equal to the width of the second slide groove 12. When one side 4a of the first baffle 4 slides to one side of the first slide groove 11, the first baffle 4 blocks the first slide groove 11, thereby preventing the operating handle 21 of the first pin assembly 2 from sliding within the first slide groove 11. Simultaneously, the other side 4b of the first baffle 4 moves away from the second slide groove 12, thereby releasing the second pin assembly 3 and allowing the operating handle 31 of the second pin assembly 3 to slide within the second slide groove 12. This ensures that when one of the first pin assembly 2 and the second pin assembly 3 extends, the other is blocked by the first baffle 4, eliminating the need for manual operation and improving ease of use.

[0022] Please see again Figures 2 to 4Preferably, the adapter socket 100 further includes a third pin assembly 7 and a second baffle 8. The third pin assembly 7 is movably disposed within the housing 1. In this embodiment, the third pin assembly 7 is pivotally connected to the housing 1 via a rotating shaft 72. When the third pin assembly 7 extends out of the housing 1, it is electrically connected to the lower connecting terminal 6. The second baffle 8 is slidably disposed within the housing 1 and located between the second pin assembly 3 and the third pin assembly 7, thereby preventing the movement of one of the second pin assembly 3 and the third pin assembly 7 and releasing the other. When the second pin assembly 3 slides out of the housing 1 through the second slide groove 12, one side of the second baffle 8 blocks the movement of the third pin. When the third pin assembly 7 moves and extends out of the housing 1, the other side of the second baffle 8 slides onto the second slide groove 12, blocking the second pin assembly 3 from sliding within the second slide groove 12. Simultaneously, the second baffle 8 pushes the first baffle 4 to slide onto the first slide groove 11, causing one side 4a of the first baffle 4 to block the first pin assembly 2 from sliding within the first slide groove 11. The sliding direction of the second baffle 8 is the same as the sliding direction of the first baffle 4. By setting the second baffle 8, it can cooperate with the first baffle 4. When one pin assembly extends out of the housing 1, the two baffles can block the other two pin assemblies, thus allowing only one pin assembly to extend. This ensures the safety of using the multi-pin adapter 100.

[0023] Please see again Figures 2 to 4Preferably, the adapter socket 100 further includes a third baffle 9. One end of the rotation shaft 72 of the third pin assembly 7 is provided with a swing portion 71. The swing portion 71 has an elongated structure, with one end fixedly connected to the rotation shaft 72 and the other end offset from the center of the rotation shaft 72. The third baffle 9 is rotatably disposed on the housing 1 so that the second baffle 8, when releasing the second pin assembly 3, together with the second baffle 8, clamps the swing portion 71. A clamping portion 91 for clamping the swing portion 71 extends from the lower side of the third baffle 9, and a pushing portion 92 extends from the upper end of the third baffle 9. The pushing portion 92 extends toward the second baffle 8 and abuts against the second baffle 8 when the second baffle 8 clamps the swing portion 71. The end face of the pushing portion 92 is provided with a apex angle 921 and an abutting plane 922. The abutting plane 922 can abut against the side of the second baffle 8 when the clamping portion 91 and the second baffle 8 jointly clamp the swing portion 71. The distance from the apex 921 to the center of rotation is greater than the distance from the abutment plane to the center of rotation. When the third pin assembly 7 rotates and extends out of the housing 1, the eccentric end of the swing part 71 pushes against the clamping part 91 of the third baffle 9, causing the third baffle 9 to rotate, which in turn causes the pushing part 92 to rotate. The pushing part 92 pushes the second baffle 8 onto the second slide groove 12 through the apex 921, thereby preventing the second pin assembly 3 from sliding in the second slide groove 12. Since the third pin assembly 7 is rotatably arranged, the third baffle 9, by rotatably arranging the third baffle 9, can clamp the swinging part 71 together with the second baffle 8, thereby preventing the third pin assembly 7 from extending. Furthermore, by extending the third baffle 9 to form a pushing part 92, the pushing part 92 drives the second baffle 8, causing the second baffle 8 and the third baffle 9 to move away from each other. Thus, when the third pin assembly 7 rotates and extends, the pushing part 92 pushes the second baffle 8 and the third baffle 9 away from each other, thereby releasing the third pin assembly 7.

[0024] Please see Figure 3 and Figure 4The first baffle 4 has an inclined first pushing slope 41 on the upper end of the side 4a near the operating handle 21 of the first pin assembly 2, so that when the first pin assembly 2 slides into the first slide groove 11, the first baffle 4 is pushed away from the first slide groove 11 by the first pushing slope 41; the first baffle 4 has an inclined second pushing slope 42 on the upper end of the other side 4b near the operating handle 31 of the second pin assembly 3, so that when the second pin assembly 3 slides into the second slide groove 12, the first baffle 4 is pushed away from the second slide groove 12 by the second pushing slope 42; the second baffle 8 has an inclined third pushing slope 81 on the side near the operating handle 31 of the second pin assembly 3, so that when the second pin assembly 3 slides into the second slide groove 12, the second baffle 8 is pushed away from the second slide groove 12 by the third pushing slope 81. By setting the first pushing slope 41, the second pushing slope 42 and the third pushing slope 81, the first baffle 4 and the second baffle 8 can automatically slide to the other side under the drive of the operating handle 21 of the first pin assembly 2 or the operating handle 31 of the second pin assembly 3, so as to automatically block other pin assemblies and improve the convenience of operation.

[0025] Based on the above and in conjunction with Figures 4 to 7, the working principle of the conversion socket 100 of this utility model will be described in detail below:

[0026] like Figure 4 As shown, when the adapter socket 100 is in a non-use state, the first pin assembly 2, the second pin assembly 3, and the third pin assembly 7 are all folded into the housing 1 and disconnected from the lower connecting terminal 6. At this time, the first pin assembly 2 is located at the upper end of the first slide groove 11, and the second pin assembly 3 is located at the upper end of the second slide groove 12. Figure 5As shown, when the first pin assembly 2 needs to be used, the operating handle 21 of the first pin assembly 2 is pushed, causing the operating handle 21 of the first pin assembly 2 to slide within the first slide groove 11. Initially, the operating handle 21 of the first pin assembly 2 pushes against the first pushing slope 41 of the first baffle 4, causing the first baffle 4 to slide towards the second slide groove 12 and block it. At this time, since the operating handle 21 of the first pin assembly 2 is located within the first slide groove 11, the first baffle 4 cannot move, thereby preventing the operating handle 31 of the second pin assembly 3 from sliding within the second slide groove 12, and the second pin assembly 3 cannot extend out of the housing 1. At the same time, during the movement of the first baffle 4, the first baffle 4 pushes against the second baffle 8, causing the second baffle 8 to move towards the direction of the third pin assembly 7. The second baffle 8 pushes the pushing part 92 to rotate, thereby causing the second baffle 8 and the clamping part 91 at the lower end of the third baffle 9 to jointly clamp the swinging part 71, and the third pin assembly 7 cannot rotate and extend out of the housing 1. When the operating handle 21 of the first pin assembly 2 is slid to the lowest end of the first slide groove 11, the first pin assembly 2 can be fully extended out of the housing 1 and electrically connected to the lower connection terminal 6. At this time, the first pin assembly 2 is in a usable state.

[0027] like Figure 6 As shown, similarly, when the second pin assembly 3 needs to be used, the first pin assembly 2 needs to be folded into the housing 1 first, so that the operating handle 21 of the first pin assembly 2 will not block the first baffle 4. At this time, the second pin assembly 3 can be pushed to slide into the second slide groove 12. Initially, the operating handle 31 of the second pin assembly 3 pushes against the first pushing slope 41 and the second pushing slope 42, thereby causing the first baffle 4 to slide towards the first slide groove 11 and finally block the first slide groove 11, thereby preventing the first pin assembly 2 from extending. Meanwhile, the second baffle 8 slides towards the swing part 71 of the third pin assembly 7 and finally clamps the swing part 71 together with the third baffle 9, thereby preventing the third pin assembly 7 from rotating and extending. At this time, a gap is formed between the first baffle 4 and the second baffle 8, which coincides with the second slide groove 12. Therefore, the second pin assembly 3 can slide into the second slide groove 12. Finally, the second pin assembly 3 slides to the bottom of the second slide groove 12, and the second pin assembly 3 can then fully extend out of the housing 1 and be electrically connected to the lower connection terminal 6. At this time, the second pin assembly 3 is in a usable state.

[0028] like Figure 7As shown, when the third pin assembly 7 needs to be used, the second pin assembly 3 must first be folded into the housing 1 so that the operating handle 31 of the second pin assembly 3 does not obstruct the second baffle 8. Then, the third pin assembly 7 can be pushed to rotate and extend out of the housing 1. At the start of rotation, the rotating shaft 72 drives the swinging part 71 to rotate. The swinging part 71 pushes the clamping part 91 of the third baffle 9, causing the third baffle 9 to rotate. The rotation of the third baffle 9 drives the pushing part 92 to rotate. The apex 921 of the pushing part 92 pushes the second baffle 8, causing the second baffle 8 to slide towards the second slide groove 12, thereby blocking the second slide groove 12 and preventing the second pin assembly 3 from extending. At this time, since the clamping parts 91 of the second baffle 8 and the third baffle 9 are both far from the swinging part 71, the swinging part 71 is unrestricted, allowing the third pin assembly 7 to fully rotate and extend out of the housing 1. After rotation, the third pin assembly 7 is electrically connected to the lower connecting terminal 6, and the third pin assembly 7 is in a usable state.

[0029] Compared with the prior art, this utility model slidably arranges a first baffle 4 on the housing 1, and positions the first baffle 4 between the first pin assembly 2 and the second pin assembly 3. This allows the first baffle 4 to block one of the first pin assembly 2 and the second pin assembly 3, while releasing the other. Therefore, when one of the first pin assembly 2 and the second pin assembly 3 extends out of the housing 1 and is in use, the operating handle of that pin assembly can block the movement of the first baffle 4, so that the first baffle 4 can only block the groove of the other pin assembly. This prevents the pin assembly from entering the corresponding groove and thus prevents it from extending out of the housing 1, effectively avoiding electric shock accidents caused by unused pin assemblies accidentally extending, thus improving safety. Furthermore, the first baffle 4 is automatically pushed and moved when the pin assembly extends, requiring no manual operation, providing automatic forced protection, ensuring both safety and convenience.

[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model shall still fall within the scope of the present utility model.
