Description

Technical Field

[0001] This application relates to the field of charging technology, and in particular to a plug mechanism and plug. Background Technology

[0002] With the development of technology, there are more and more types of electronic products, and there are also more and more plugs used for electronic products. By inserting the plug's prongs into the socket, electronic products can be charged.

[0003] However, the prongs of the plug are usually fixed to the plug housing, and the plug is relatively large, making it inconvenient to carry and store. Utility Model Content

[0004] This application provides a plug mechanism and plug, which can reduce the storage volume of the plug, making it more convenient to carry and store.

[0005] In a first aspect, this application provides a pin mechanism, comprising:

[0006] The outer casing has a receiving groove and a clearance opening communicating with the receiving groove;

[0007] A pin assembly includes pins and a support shaft. The pins pass through the recessed opening and are rotatably connected to the housing via the support shaft about the axis of the support shaft. The extension direction of the pins is perpendicular to the extension direction of the axis of the support shaft. The rotation trajectory of the pins has a retracted position and a first unfolded position.

[0008] An elastic conductive element is located within the receiving groove and connected to the outer casing;

[0009] An elastic limiting member is located within the receiving groove and is connected to the outer shell;

[0010] When the plug is in the retracted position, the plug and the elastic conductive element are spaced apart, and the elastic limiting element elastically abuts against the plug assembly, so that the elastic limiting element undergoes elastic deformation, thereby providing rotational resistance to the plug; when the plug is in the first unfolded position, the plug and the elastic conductive element elastically abut against each other, so that the elastic conductive element undergoes elastic deformation, thereby providing rotational resistance to the plug.

[0011] Secondly, this application also provides a plug, including an electronic control component, a second housing, and a pin mechanism. The second housing is disposed opposite to the recess opening and is connected to the outer shell to form a receiving cavity with the outer shell. The electronic control component is disposed in the receiving cavity and is electrically connected to the pins through the elastic conductive element.

[0012] The beneficial effects of this application are as follows: the plug's rotation trajectory has a retracted position and a first extended position. When the plug is in the retracted position, the plug mechanism is smaller, resulting in a smaller plug. When carrying and storing the plug, the plug can be rotated to the retracted position, making it more convenient to carry and store. When the plug is in the retracted position, the plug mechanism is in an unusable state, and the plug is separated from the elastic conductive element, preventing the plug from contacting the elastic conductive element. This prevents accidental contact between the plug and the power supply, which could damage the electronic control components or cause electric shock to the user. Furthermore, at this time, the elastic limiting element undergoes elastic deformation due to contact with the plug, which can limit the movement of the plug. The positioning element provides rotational resistance to the pins, allowing them to remain stably in the retracted position and preventing accidental rotation due to external forces or vibrations, thereby improving the safety and reliability of the pin mechanism. Furthermore, when the pins are in the first extended position, they abut against the elastic conductive element, enabling electrical connection between the pins and the electronic control components. This allows the pin mechanism to operate normally. Simultaneously, the elastic conductive element undergoes elastic deformation due to contact with the pins, providing rotational resistance to the pins and ensuring they remain stably in the first extended position, preventing accidental rotation due to external forces or vibrations, thus improving the reliability of the pin mechanism during operation.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] This application provides a plug mechanism and plug to solve the problem that in related technologies, the plug prongs are usually fixed on the plug housing, and the plug is large in size, which makes it inconvenient to carry and store the plug.

[0035] Firstly, this application provides a pin mechanism, such as... Figure 1 and Figure 2 As shown, the pin mechanism includes a housing 10 and a pin assembly.

[0036] The outer casing 10 has a receiving groove 11 (such as...) Figure 3 The outer shell 10 has a recess opening 12 that communicates with the receiving groove 11; the overall shape of the outer shell 10 can be a cuboid, cube, cylinder or other shape, and this application does not impose any specific restrictions.

[0037] The plug assembly includes a plug 21 and a support shaft 22. The plug 21 passes through a recess opening 12 and is rotatably connected to the housing 10 via the support shaft 22 about its axis X, allowing the plug 21 to rotate about the axis X. The extension direction of the plug 21 is perpendicular to the extension direction of the axis X. It is understood that the recess opening 12 provides rotational space for the plug 21. The plug 21 is made of metal. The head end of the plug 21 is used for insertion into the socket, and the tail end of the plug 21 is used for connection to the support shaft 22 and to the electrical control component 50 (such as...) in the plug. Figure 17The plug is connected via pin 21 to achieve electrical connection between the plug and the device to be charged, thereby enabling charging of the device to be charged. The device to be charged can be a mobile phone, tablet, gaming device, AR (Augmented Reality) device, data storage device, audio playback device, video playback device, desktop computing device, or wearable device. Wearable devices can be electronic watches, electronic glasses, electronic helmets, electronic bracelets, electronic necklaces, etc.

[0038] Among them, such as Figures 1 to 7 As shown, the rotation trajectory of pin 21 has a storage position (such as...). Figures 1 to 4 ) and the first unfolding position (e.g. Figures 5 to 7 The retracted position and the first extended position are two positions on the rotation trajectory of the plug 21. The plug 21 can rotate from the retracted position to the first extended position in a clockwise or counterclockwise direction. The length of the part of the plug 21 extending out of the outer casing 10 in the retracted position is less than the length of the part of the plug 21 extending out of the outer casing 10 in the first extended position, making the plug mechanism smaller in the retracted position, and thus making the plug using the plug mechanism smaller. When it is necessary to carry and store the plug, the plug 21 can be rotated to the retracted position, making it more convenient to carry and store the plug; when it is necessary to charge the plug, the plug 21 can be rotated to the first extended position, at which time the length of the part of the plug 21 extending out of the outer casing 10 is longer, making it easier to insert the plug 21 into the socket hole.

[0039] Specifically, the pin mechanism also includes an elastic conductive element 30 and an elastic limiting element 40. Both the elastic conductive element 30 and the elastic limiting element 40 are formed of elastic material (such as elastic steel), and both the elastic conductive element 30 and the elastic limiting element 40 are capable of elastic deformation.

[0040] The elastic conductive element 30 is located in the receiving groove 11 and connected to the outer shell 10. The elastic conductive element 30 is used as a connector between the pin 21 and the electronic control component 50, so that the pin 21 and the electronic control component 50 can be electrically connected. The elastic limiting element 40 is located in the receiving groove 11 and connected to the outer shell 10.

[0041] like Figure 3 and Figure 4 As shown, when the pin 21 is in the retracted position, the pin 21 and the elastic conductive element 30 are spaced apart, and the elastic limiting element 40 elastically abuts against the pin assembly, so that the elastic limiting element 40 undergoes elastic deformation, thereby providing rotational resistance to the pin 21; as Figure 6 and Figure 7As shown, when the pin 21 is in the first unfolded position, the pin 21 abuts against the elastic conductive element 30, so that the elastic conductive element 30 undergoes elastic deformation, thereby providing rotational resistance to the pin 21.

[0042] Understandably, when pin 21 is in the retracted position, the pin mechanism is in an unusable state. Pin 21 is separated from the elastic conductive element 30, preventing contact between them. This prevents pin 21 from conducting electricity to the electronic control component 50 via the elastic conductive element 30, thus preventing accidental contact between pin 21 and the power supply, which could damage the electronic control component 50 or cause electric shock to the user. Furthermore, the elastic limiting element 40, due to its contact with pin 21, undergoes elastic deformation, providing rotational resistance to pin 21. This allows pin 21 to remain stably in the retracted position, preventing accidental rotation due to external force or vibration, thereby improving the safety and reliability of the pin mechanism. In addition... When the pin 21 is in the first unfolded position, the pin 21 abuts against the elastic conductive element 30, allowing the pin 21 to be electrically connected to the electronic control component 50 through the elastic conductive element 30, thereby enabling the pin mechanism to work normally. At the same time, the elastic conductive element 30 undergoes elastic deformation due to abutting against the pin 21, providing rotational resistance to the pin 21, so that the pin 21 can be stably stopped in the first unfolded position, preventing the pin 21 from rotating accidentally due to external force or vibration. This can improve the reliability of the pin mechanism during operation, and eliminate the need for additional stabilizing elements to keep the pin 21 stably stopped in the first unfolded position, reducing the number of components in the pin mechanism and making the pin mechanism easier to assemble and manufacture.

[0043] like Figure 3 and Figure 8 As shown, the elastic conductive element 30 has a first slot 31 on the side facing the pin 21. When the pin 21 is in the first unfolded position, the pin 21 engages with the first slot 31, so that the elastic conductive element 30 can provide greater rotational resistance to the pin 21, thereby locking the pin 21 in the first unfolded position. This allows the pin 21 to stay more stably in the first unfolded position, improving the reliability of the pin mechanism during operation. Furthermore, the pin 21 can rotate under external force (such as a person manually moving the pin 21), allowing the pin 21 to disengage from the first slot 31 and unlock, thus ensuring that the pin 21 can smoothly rotate to other positions. In addition, the contact between the pin 21 and the slot wall of the first slot 31 can increase the contact area between the pin 21 and the elastic conductive element 30, making the electrical connection between the pin 21 and the elastic conductive element 30 more stable.

[0044] In some embodiments, when the plug 21 switches between the retracted position and the first extended position, the plug 21 remains elastically abutting against the elastic conductive element 30, so that the plug 21 is always subject to the movement resistance of the elastic conductive element 30 when switching between the retracted position and the first extended position, which can provide customers with obvious tactile feedback and thus improve the user experience. In addition, the rotational resistance provided by the elastic conductive element 30 can be used to allow the plug 21 to stop in other positions besides the retracted position and the first extended position, and the plug 21 also maintains contact with the elastic conductive element 30 in other positions, so that the plug 21 can have more working angles, and the angle of the plug 21 can be flexibly adjusted when encountering different types of sockets.

[0045] In some embodiments, the plug 21 includes a plug portion 211 and a contact portion 212 connected to the plug portion 211; the plug portion 211 passes through the recess opening 12 and is rotatably connected to the housing 10 via a support shaft 22 about the axis X of the support shaft 22; the plug portion 211 is the part of the plug 21 used to be plugged into the socket hole of the socket; the contact portion 212 is the part of the plug 21 used to contact the elastic conductive member 30; both the contact portion 212 and the plug portion 211 are conductors; the contact portion 212 and the plug portion 211 can be integrally formed or separately formed and then spliced.

[0046] The elastic conductive element 30 includes a wiring portion 33 and an elastic portion 34 connected to the wiring portion 33. The elastic portion 34 is located to the side of the contact portion 212. It is understood that the wiring portion 33 is the part used for electrical connection with the electronic control component 50. Both the elastic portion 34 and the wiring portion 33 are conductors. The elastic portion 34 and the wiring portion 33 can be integrally formed or separately formed and then spliced.

[0047] Among them, such as Figure 3 As shown, when the pin 21 is in the retracted position, the contact portion 212 and the elastic conductive element 30 are spaced apart, so that the pin 21 and the elastic conductive element 30 are spaced apart; as Figure 6 As shown, when the pin 21 is in the first unfolded position, the contact portion 212 elastically abuts against the elastic conductive member 30 to achieve electrical connection between the pin 21 and the elastic conductive member 30, thereby achieving electrical connection between the pin 21 and the electronic control component 50. Furthermore, the contact portion 212 compresses the elastic portion 34, causing the elastic portion 34 to undergo elastic deformation. This provides sufficient rotational resistance to the pin 21 through the elastic portion 34, and makes the contact between the pin 21 and the elastic portion 34 tighter, ensuring the reliability of the electrical connection between the pin 21 and the elastic conductive member 30.

[0048] Furthermore, such as Figure 6 and Figure 9As shown, the contact portion 212 and the plug portion 211 are arranged at intervals along the extension direction of the axis X of the support shaft 22. The elastic conductive element 30 and the plug portion 211 are located on the same side of the contact portion 212. The elastic part 34 is located on the side of the contact portion 212 away from the support shaft 22, and the elastic part 34 extends along the rotation trajectory of the contact portion 212. This allows the plug 21 to be pressed and deformed by the contact portion 212 when switching between the retracted position and the first unfolded position. This ensures the reliability of the electrical connection between the plug 21 and the elastic conductive element 30 when switching between the retracted position and the first unfolded position. Furthermore, the plug 21 can rotate smoothly under the action of external force, preventing the plug 21 from being blocked by the elastic conductive element 30 and causing jamming.

[0049] It should also be noted that the pin 21 can be formed together with the support shaft 22 by in-mold injection molding. Part of the pin 21 is covered inside the support shaft 22, which can improve the connection strength between the pin 21 and the support shaft 22. The contact part 212 extends out of the support shaft 22 to facilitate the contact part 212 and the elastic conductive element 30.

[0050] In some embodiments, the first slot 31 is located at the connection between the wiring portion 33 and the elastic portion 34. When the pin 21 is in the first unfolded position, the contact portion 212 engages with the first slot 31 to... Figure 6 Taking the shown perspective as an example, when the plug 21 is rotated counterclockwise to the storage position, the contact part 212 rotates counterclockwise to disengage from the first slot 31 and rotates towards the wiring part 33. Subsequently, the contact part 212 gradually moves away from the elastic conductive member 30. When the plug 21 is rotated to the storage position, the contact part 212 separates from the elastic conductive member 30 to disconnect the electrical connection with the elastic conductive member 30.

[0051] like Figures 10 to 12 As shown in some embodiments of this application, the rotation trajectory of the plug 21 also includes a second unfolded position. The storage position, the first unfolded position, and the second unfolded position are arranged sequentially. When the plug 21 is in the first unfolded position, the plug 21 elastically abuts against the elastic conductive member 30, so that the elastic conductive member 30 provides rotational resistance to the plug 21. It can be understood that the second unfolded position and the first unfolded position are two different positions. When charging is required using the plug mechanism, the plug 21 can also be rotated to the second unfolded position. The plug 21 has two working positions, the first unfolded position and the second unfolded position, so that the angle of the plug 21 can be flexibly adjusted when encountering different types of sockets, so that the plug 21 can be inserted into the socket hole more conveniently, preventing problems such as unstable plugging, blocking of adjacent sockets, and interference with other plugs around it.

[0052] In some embodiments, the elastic conductive element 30 is provided with a second slot 32 on the side facing the pin 21. When the pin 21 is in the second unfolded position, the pin 21 engages with the second slot 32, so that the elastic conductive element 30 can provide greater rotational resistance to the pin 21, thereby locking the pin 21 in the second unfolded position. This allows the pin 21 to stop more stably in the second unfolded position, improving the reliability of the pin mechanism during operation. In addition, the contact between the pin 21 and the slot wall of the second slot 32 can increase the contact area between the pin 21 and the elastic conductive element 30, making the electrical connection between the pin 21 and the elastic conductive element 30 more stable.

[0053] Specifically, the second slot 32 is located in the elastic part 34, and the second slot 32 and the first slot 31 are arranged sequentially along the rotation trajectory of the contact part 212, so as to... Figure 11 Taking the shown perspective as an example, when the plug 21 is in the second unfolded position, the contact part 212 engages with the second slot 32. At this time, when the plug 21 is rotated counterclockwise, the contact part 212 disengages from the second slot 32 and remains against the elastic part 34. When the plug 21 is rotated to the first unfolded position, the contact part 212 engages with the first slot 31. Then, the plug 21 is rotated counterclockwise, and the contact part 212 disengages from the first slot 31. When the plug 21 is rotated to the first retracted position, the contact part 212 separates from the conductive connection part.

[0054] In some embodiments, the support shaft 22 is rotatably connected to the housing 10 about the axis X of the support shaft 22, and the pin 21 is connected to the support shaft 22. The pin 21 can rotate with the support shaft 22. The pin 21 and the support shaft 22 form a coaxial rotation mechanism to realize the synchronous linkage of the pin assembly.

[0055] Among them, such as Figure 4 As shown, the peripheral surface of the support shaft 22 includes a positioning surface 221. An elastic limiting member 40 is located to the side of the positioning surface 221. The side of the elastic limiting member 40 closest to the support shaft 22 has a limiting surface 41. When the pin 21 is in the retracted position, the limiting surface 41 elastically abuts against the positioning surface 221 to provide rotational resistance to the pin 21. It can be understood that the elastic limiting member 40 provides rotational resistance to the support shaft 22, thereby providing rotational resistance to the pin 21. The elastic limiting member 40 does not directly contact the pin 21, preventing short circuits between the pin 21 and other components through the elastic limiting member 40. Furthermore, the elastic limiting member 40 and the elastic conductive member 30 act on the support shaft 22 and the pin 21 respectively, allowing the elastic limiting member 40 and the elastic conductive member 30 to be arranged alternately, making their arrangement more convenient. The elastic limiting member 40 can be formed of an insulating material to prevent short circuits between the pin 21 and the elastic limiting member 40.

[0056] Further, the positioning surface 221 includes a first abutment surface 221a and a second abutment surface 221b arranged circumferentially along the support shaft 22, the first abutment surface 221a and the second abutment surface 221b being arranged at an included angle; wherein, as Figure 4 As shown, when the pin 21 is in the retracted position, the elastic limiting member 40 elastically abuts against the first abutting surface 221a; as Figure 7 As shown, when the pin 21 is in the first unfolded position, the elastic limiting member 40 elastically abuts against the first contact surface.

[0057] Understandably, compared to setting the positioning surface 221 as an arc surface that extends continuously around the axis X, the contact area between the limiting surface 41 and the positioning surface 221 is small. When the elastic limiting member 40 abuts against the positioning surface 221, slippage is likely to occur. The elastic limiting member 40 provides less rotational resistance to the support shaft 22. In this application, the first abutting surface 221a and the second abutting surface 221b are located on different planes. When the support shaft 22 rotates, the position and orientation of the pin 21 change, and the positions of the first abutting surface 221a and the second abutting surface 221b also change. This allows the elastic limiting member 40 to abut against the first abutting surface 221a and the second abutting surface 221b respectively when the pin 21 is in the retracted position and the first unfolded position. The contact area between the elastic limiting member 40 and the first abutting surface 221a and the second abutting surface 221b is large, which can provide greater rotational resistance to the support shaft 22, thereby allowing the pin 21 to be stably stopped in the retracted position.

[0058] In some embodiments, such as Figure 12 As shown, the positioning surface 221 also includes a third abutting surface 221c. The first abutting surface 221a, the second abutting surface 221b and the third abutting surface 221c are arranged sequentially along the circumference of the support shaft 22. When the pin 21 is in the second unfolded position, the elastic limiting member 40 elastically abuts against the third abutting surface 221c, thereby providing greater rotational resistance to the support shaft 22, so that the pin 21 can be stably stopped in the second unfolded position.

[0059] like Figure 9 As shown, in some embodiments, two pins 21 are provided. The two pins 21 are arranged at intervals along the extension direction of the axis X of the support shaft 22, and the two pins 21 are connected to both ends of the support shaft 22. The two pins 21 are equipped with two elastic conductive elements 30, and the elastic conductive elements 30 are arranged one-to-one with the pins 21. The two pins 21 can rotate synchronously with the support shaft 22, and the two pins 21 are respectively subjected to the motion resistance provided by the two elastic conductive elements 30, so that both ends of the support shaft 22 are subjected to force when rotating, and the force on the support shaft 22 is more uniform. This can prevent the support shaft 22 from tilting due to force on one end, which would cause the support shaft 22 to jam.

[0060] In some embodiments, the positioning surface 221 is located in the middle of the support shaft 22. Compared to setting the positioning surface 221 at the end of the support shaft 22, in order to prevent the support shaft 22 from tilting due to force on one end and causing the support shaft 22 to jam, two positioning surfaces 221 need to be set at both ends of the support shaft 22, and two elastic limiting members 40 need to be provided for each of the two positioning surfaces 221. This will increase the cost of the pin mechanism, and in order to provide sufficient space to accommodate the two elastic limiting members 40, the outer shell 10 needs to have a larger volume, which will increase the volume of the plug. In this embodiment, the positioning surface 221 is set in the middle of the support shaft 22, and the overall force on the support shaft 22 is more uniform. Only one positioning surface 221 needs to be set, and one elastic limiting member 40 needs to be provided for the positioning surface 221. This can reduce the production cost of the pin mechanism, reduce the volume of the plug, and increase the distance between the elastic limiting member 40 and the elastic conductive member 30 to prevent the elastic limiting member 40 and the elastic conductive member 30 from affecting each other.

[0061] Continue to participate Figure 12 As shown, in some embodiments, the elastic limiting member 40 includes an elastic limiting portion 42 and two elastic arms 43. The elastic limiting portion 42 has a limiting surface 41; the two elastic arms 43 are respectively connected to both ends of the elastic limiting portion 42 and are connected to the outer casing 10. It should be noted that both the elastic limiting portion 42 and the elastic arms 43 are elastic, so that during the rotation of the support shaft 22, the elastic limiting member 40 can elastically extend and retract in the direction intersecting with the axis X, thereby ensuring that the elastic limiting member 40 always remains in contact with the positioning surface 221, thus providing rotational resistance to the support shaft 22 during the rotation of the pin 21.

[0062] It should also be noted that, compared to using a spring sheet to provide rotational resistance for the support shaft 22, where the first end of the spring sheet is fixed and the second end is raised and in contact with the support shaft 22, during use, because the second end of the spring sheet is not supported, it is prone to wear, loosening, and bending, resulting in the spring sheet not being able to provide stable rotational resistance for the support shaft 22, thus shortening the stability and lifespan of the plug. In this embodiment, both ends of the elastic limiting part 42 are connected to the outer shell 10 through elastic arms 43, so that both ends of the elastic limiting part 42 are supported, allowing the support shaft 22 to rotate. When the limiting surface 41 switches between different contact surfaces (first contact surface 221a, second contact surface 221b and third contact surface 221c), the elastic limiting member 40 will generate non-linear deformation characteristics, which will cause the elastic force applied by the elastic limiting member 40 to the support shaft 22 to gradually change, providing rotational resistance to the support shaft 22. This makes the elastic force applied by the elastic limiting part 42 to the support shaft 22 more stable, and thus makes the motion resistance applied by the elastic limiting member 40 to the support shaft 22 more stable, which can improve the stability and life of the pin mechanism.

[0063] like Figure 13 and Figure 14 As shown, in some embodiments of this application, the outer casing 10 includes a first housing 13 and a mounting bracket 14; the first housing 13 has a receiving groove 11 and a clearance opening 12; the mounting bracket 14 is located in the receiving groove 11, and the mounting bracket 14 is located on the side of the support shaft 22 near the clearance opening 12, and the pin 21 is rotatably connected to the mounting bracket 14 through the support shaft 22.

[0064] The pin 21 is rotatably connected to the mounting bracket 14. The mounting bracket 14 has a first mounting groove 141 and a second mounting groove 142 on the side facing the support shaft 22. The elastic conductive element 30 and the elastic limiting element 40 are respectively located in the first mounting groove 141 and the second mounting groove 142. It can be understood that the pin 21 is rotatably connected to the mounting bracket 14 through the support shaft 22, which makes the connection between the support shaft 22 and the first housing 13 more convenient, and eliminates the need to open a shaft hole for mounting the support shaft 22 on the first housing 13, so that the outer surface of the first housing 13 can have a larger usable area for mounting devices such as displays. In addition, by accommodating the elastic conductive element 30 and the elastic limiting element 40 in the first mounting groove 141 and the second mounting groove 142 respectively, the space occupied by the mounting bracket 14 can be fully utilized, making the arrangement of the devices in the accommodating groove 11 more compact, thereby reducing the volume of the housing 10 and thus reducing the volume of the pin mechanism.

[0065] In some embodiments, a limiting post 15 is provided on the mounting bracket 14, and the elastic conductive element 30 is sleeved on the limiting post 15, thereby realizing the positioning and installation of the elastic conductive element 30.

[0066] In some embodiments, the housing 10 further includes a cover 16 located on the side of the support shaft 22 away from the mounting bracket 14 and connected to the mounting bracket 14. The cover 16 is used to limit the support shaft 22 and prevent the support shaft 22 from detaching from the mounting bracket 14.

[0067] like Figure 15 As shown, in some embodiments, when the pin 21 is in the retracted position, the extension direction of the pin 21 is the first direction; when the pin 21 is in the first unfolded position, the extension direction of the pin 21 is the second direction, and the angle formed by the first direction and the second direction is α, where 0 degrees < α < 90 degrees.

[0068] It should be noted that the extension direction of the pin 21 is the same as the extension direction of the plug portion 211. Compared to designing α to be greater than or equal to 90 degrees, in this application, α is less than 90 degrees, making α smaller. This allows the pin 21 to have a shorter travel distance when switching between the retracted position and the first unfolded position, thus making the switching between the retracted position and the first unfolded position faster and more convenient. In addition, since the rotation range of the pin 21 is smaller, the length of the clearance opening 12 that provides the movement space for the pin 21 on the movement trajectory of the pin 21 can be designed to be shorter. This results in the clearance opening 12 occupying a smaller area on the outer surface of the housing 10, thereby allowing the outer surface of the housing 10 to have a larger usable area for mounting devices such as displays.

[0069] In some embodiments, during the rotation stroke of the plug 21, when the plug 21 is in the retracted position, the length of the part of the plug 21 extending out of the housing 10 is the shortest, making the plug the smallest in size and more convenient to carry and store; when the plug 21 is in the first unfolded position, the length of the part of the plug 21 extending out of the housing 10 is the longest, making it more convenient to insert the plug 21 into the socket and improving the connection strength between the plug 21 and the socket.

[0070] In some embodiments, 45 degrees ≤ α ≤ 85 degrees. It is understood that, for ease of use of the pin 21, the length of the portion of the pin 21 extending beyond the housing 10 is at its maximum when the pin 21 is in the first unfolded position. As the pin 21 rotates from the first unfolded position to the retracted position, the length of the portion extending beyond the housing 10 typically decreases gradually. When α is less than 45 degrees, the length of the portion extending beyond the housing 10 in the retracted position will be relatively large, resulting in a larger plug size. When α is greater than 85 degrees, the rotation range of the pin 21 is too large, requiring a longer length of the clearance opening 12 along the movement trajectory of the pin 21. α can be 74 degrees; however, depending on actual needs, α can also be 45 degrees, 50 degrees, 65 degrees, 85 degrees, or other degrees.

[0071] In some embodiments, the clearance opening 12 extends along the rotation trajectory of the pin 21, and the inner wall surface of the clearance opening 12 includes a first wall surface 121 (e.g., Figure 5 Along the rotation trajectory of the pin 21, the first wall surface 121 is located on the side of the storage position away from the first unfolded position. When the pin 21 is in the storage position, the pin 21 contacts the first wall surface 121 to prevent the pin 21 from continuing to rotate away from the first unfolded position, so that the pin 21 can be conveniently and stably stopped in the storage position. The first wall surface 121 is also the end position of one end of the clearance opening 12, so there is no need to provide more rotation space for the pin 21, so that the length of the clearance opening 12 can be designed to be shorter, thereby making the clearance opening 12 occupy a smaller area on the outer surface of the outer shell 10.

[0072] In some embodiments, when the pin 21 is in the second extended position, the extension direction of the pin 21 is the third direction C, the angle formed by the third direction C and the second direction B is 90 degrees, and the third abutment surface 221c is perpendicular to the second abutment surface 221b, so that the position of the outer shell 10 of the pin mechanism on the socket can be adjusted within a large angle range, preventing the outer shell 10 from blocking the adjacent socket and interfering with other plugs around it after the pin 21 is inserted into the socket hole.

[0073] Secondly, based on the aforementioned pin mechanism, this application also provides a plug, such as... Figure 16 and Figure 17 As shown, the plug includes an electronic control component 50, a second housing 60, and a pin mechanism as described in any of the above embodiments. The second housing 60 is disposed opposite to the clearance opening 12. The second housing 60 is connected to the outer shell 10 to form a receiving cavity with the outer shell 10. The electronic control component 50 is disposed in the receiving cavity and is electrically connected to the pin 21 through an elastic conductive member 30.

[0074] The second housing 60 is connected to the first housing 13 to form a container. The electronic control component 50 may include a control circuit board. The control circuit board is electrically connected to the elastic conductive member 30 through a conductive connecting line, thereby realizing the electrical connection between the electronic control component 50 and the pin 21.

[0075] 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.
