Description

Technical Field

[0001] This application relates to the field of charging technology, and in particular to a plug assembly 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 assembly and plug that 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 assembly, comprising:

[0006] The first housing has a receiving groove and a clearance opening communicating with the receiving groove;

[0007] A rotating shaft is located in the receiving groove and is rotatably connected to the first housing about a first axis. The peripheral side of the rotating shaft includes a positioning surface. The positioning surface includes a first abutting surface and a second abutting surface arranged along the circumference of the rotating shaft. The first abutting surface and the second abutting surface are arranged at an angle.

[0008] A pin, passing through the recessed opening, is connected to the rotating shaft. The extension direction of the pin is perpendicular to the first axial direction. The rotating shaft can rotate with the pin, and the rotation trajectory of the pin has a retracted position and a first extended position; and...

[0009] A limiting component is located inside the receiving groove and to the side of the positioning surface. The limiting component abuts against the positioning surface. When the pin rotates, the limiting component elastically extends and retracts in a direction that forms an angle with the first axis.

[0010] When the pin is in the storage position, the extension direction of the pin is a first direction, and the limiting component abuts against the first contact surface to fix the rotating shaft; when the pin is in the first unfolded position, the extension direction of the pin is a second direction, and the limiting component abuts against the second contact surface to fix the rotating shaft, and the angle formed by the first direction and the second direction is α, where 0 degrees < α < 90 degrees.

[0011] Secondly, this application also provides a plug, including an electronic control component, a second housing, and a pin assembly. The second housing is disposed opposite to the recessed opening and is connected to the first housing to form a receiving cavity. The electronic control component is disposed in the receiving cavity and is electrically connected to the pins.

[0012] The beneficial effects of this application are as follows: When it is necessary to carry and store the plug, the prongs can be rotated to the storage position, making it more convenient to carry and store the plug. Furthermore, when the prongs switch between the storage position and the first extended position, the elastic extension and retraction of the limiting component allows the limiting component to remain abutting against the positioning surfaces (including the first and second contact surfaces), thereby providing appropriate rotational resistance to the prongs. This design ensures that the prongs can stably remain in the target position when switching between the storage position and the first extended position, preventing accidental rotation due to external force or vibration. In addition, the travel distance of the prongs when switching between the storage position and the first extended position can be shorter, making the switching between these positions faster and more convenient. Moreover, because the rotation range of the prongs is smaller, the length of the clearance opening providing space for the prongs along the prongs' movement trajectory can be designed to be shorter, resulting in a smaller area occupied by the clearance opening on the outer surface of the first housing. This allows for a larger usable area on the outer surface of the first housing for mounting devices such as displays. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] This application provides a plug assembly and plug to solve the problem in the related art where the plug prongs are usually fixed on the plug housing, resulting in a large plug size and inconvenience in carrying and storing the plug.

[0031] Firstly, this application provides a pin assembly, such as... Figure 1 and Figure 2 As shown, the pin assembly includes a first housing 10, a rotating shaft 20, and pins 30.

[0032] The first housing 10 has a receiving groove 11 and a clearance opening 12 communicating with the receiving groove 11. The first housing 10 is used to provide mounting positions and protection for devices such as pins 30. The overall shape of the first housing 10 can be a cuboid, a cube, a cylinder or other shapes, and this application does not impose any specific restrictions.

[0033] The rotating shaft 20 is located in the receiving groove 11 and is rotatably connected to the first housing 10 about the first axis X. The first axis X is the extension direction of the axis of rotation of the rotating shaft 20. The rotating shaft 20 can rotate relative to the first housing 10 about the first axis X.

[0034] The plug 30 passes through the recess opening 12 and is connected to the rotating shaft 20. The extension direction of the plug 30 is perpendicular to the first axis X, and the rotating shaft 20 can rotate with the plug 30. The plug 30 is rotatably connected to the first housing 10 through the rotating shaft 20. The recess opening 12 provides rotation space for the plug 30. The plug 30 is made of metal. The head end of the plug 30 is used to insert into the socket, and the tail end of the plug 30 is used to connect to the rotating shaft 20 and to the electrical control component 91 in the plug (such as...). Figure 12 The connector is connected via pin 30 to electrically connect the plug to the device to be charged, thereby enabling charging of the device. 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 include electronic watches, electronic glasses, electronic helmets, electronic bracelets, electronic necklaces, etc.

[0035] Among them, see Figures 1 to 4 As shown, the rotation trajectory of pin 30 has a storage position (such as...). Figure 1 and Figure 2 ) and the first unfolding position (e.g. Figure 3 and Figure 4The retracted position and the first extended position are two positions on the rotation trajectory of the prong 30. The prong 30 can rotate from the retracted position to the first extended position in either a clockwise or counterclockwise direction. The length of the prong 30 extending beyond the first housing 10 in the retracted position is less than the length of the prong 30 extending beyond the first housing 10 in the first extended position. This makes the prong assembly smaller in the retracted position, resulting in a smaller plug. When carrying and storing the plug is needed, the prong 30 can be rotated to the retracted position for easier carrying and storage. When charging is needed, the prong 30 can be rotated to the first extended position, where the length of the prong 30 extending beyond the first housing 10 is longer, making it easier to insert the prong 30 into the socket.

[0036] Specifically, the circumferential surface of the rotating shaft 20 includes a positioning surface 21, and the pin assembly also includes a limiting component 40. The limiting component 40 is located within the receiving groove 11 and to the side of the positioning surface 21. The limiting component 40 abuts against the positioning surface 21. When the pin 30 rotates, the limiting component 40 elastically extends and retracts in a direction that forms an angle with the first axis X. It can be understood that when the pin 30 switches between the retracted position and the first unfolded position, the elastic extension and retraction of the limiting component 40 allows it to remain abutted against the positioning surface 21. This provides appropriate rotational resistance to the pin 30, ensuring that the pin 30 can stably remain in the target position when switching between the retracted and first unfolded positions, preventing accidental rotation due to external force or vibration. Furthermore, the rotational resistance provided by the limiting component 40 during the pin 30's rotation provides clear tactile feedback to the customer, thereby improving the user experience.

[0037] More specifically, the positioning surface 21 includes a first abutting surface 211 and a second abutting surface 212 arranged circumferentially along the rotation axis 20. The first abutting surface 211 and the second abutting surface 212 are arranged at an angle. When the plug 30 is in the storage position, the extension direction of the plug 30 is the first direction A, and the limiting component 40 abuts against the first abutting surface 211 to fix the rotation axis 20. When the plug 30 is in the first unfolded position, the extension direction of the plug 30 is the second direction B, and the limiting component 40 abuts against the second abutting surface 212 to fix the rotation axis 20.

[0038] Understandably, compared to setting the positioning surface 21 as an arc surface continuously extending around the first axis X, the contact area between the limiting component 40 and the positioning surface 21 is smaller, making slippage more likely when the limiting component 40 abuts against the positioning surface 21. This results in less rotational resistance provided by the limiting component 40 to the rotating shaft 20. In this application, the first wall surface 121 and the second wall surface are located on different planes. When the rotating shaft 20 rotates, the position and orientation of the pin 30 change, and the positions of the first abutment surface 211 and the second abutment surface 212 also change. For example, using... Figure 2 Taking the shown perspective as an example, when the pin 30 is in the storage position, the first abutment surface 211 faces upwards, and the second abutment surface 212 faces left. Figure 4 Taking the shown viewpoint as an example, pin 30 is... Figure 2 Rotate the storage compartment clockwise to... Figure 4 When the first unfolded position is reached, the first abutment surface 211 moves to face right and the second abutment surface 212 moves to face upward. This allows the limiting component 40 to abut against the first abutment surface 211 and the second abutment surface 212 respectively when the pin 30 is in the retracted position and the first unfolded position. The large contact area between the limiting component 40 and the first abutment surface 211 and the second abutment surface 212 provides greater rotational resistance to the rotating shaft 20, thereby allowing the pin 30 to be stably stopped in the retracted position and the first unfolded position, preventing the pin 30 from rotating accidentally due to external force or vibration.

[0039] Among them, such as Figure 5 As shown, the angle formed by the first direction A and the second direction B is α, where 0 degrees < α < 90 degrees. It should be noted that, 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 for a shorter travel distance of the pin 30 when switching between the retracted and first unfolded positions, resulting in faster and more convenient switching. Furthermore, because the rotation range of the pin 30 is smaller, the length of the clearance opening 12 providing space for the pin 30 along its trajectory can be designed to be shorter. This results in a smaller area occupied by the clearance opening 12 on the outer surface of the first housing 10, allowing for a larger usable area on the outer surface of the first housing 10 for mounting devices such as displays.

[0040] In some embodiments, during the rotation stroke of the plug 30, when the plug 30 is in the retracted position, the length of the part of the plug 30 extending outside the first housing 10 is the shortest, making the plug the smallest in size and more convenient to carry and store; when the plug 30 is in the first unfolded position, the length of the part of the plug 30 extending outside the first housing 10 is the longest, making it more convenient to insert the plug 30 into the socket and improving the connection strength between the plug 30 and the socket.

[0041] In some embodiments, 45 degrees ≤ α ≤ 85 degrees. It is understood that, for ease of use of the pin 30, the length of the portion of the pin 30 extending beyond the first housing 10 is at its maximum when the pin 30 is in the first unfolded position. As the pin 30 rotates from the first unfolded position to the retracted position, the length of the portion extending beyond the first housing 10 typically decreases gradually. When α is less than 45 degrees, the length of the portion extending beyond the housing in the retracted position is relatively large, resulting in a larger plug size. When α is greater than 85 degrees, the rotation range of the pin 30 is too large, requiring a longer length of the clearance opening 12 along the movement trajectory of the pin 30. 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.

[0042] See also Figure 4 As shown, in some embodiments, the included angle formed by the first abutment surface 211 and the second abutment surface 212 is β1, where α + β1 = 180 degrees. For example, when α is 16 degrees, β1 is 174 degrees. It is understood that, see [reference needed] Figure 2 and Figure 4 As shown, the side of the limiting component 40 that abuts against the positioning surface 21 is the limiting surface 411. The first axis K1 of the first abutting surface 211 is perpendicular to the first abutting surface 211. The second axis K2 of the second abutting surface 212 is perpendicular to the second abutting surface 212. The third axis K3 of the limiting surface 411 is perpendicular to the limiting surface 411. The angle between the first axis K1 and the second axis K2 is β2, where β1 + β2 = 180 degrees. See also... Figure 2 As shown, at this time, the first abutting surface 211 can be parallel and fit against the limiting surface 411, and the first axis K1 coincides with the third axis K3, thereby increasing the contact area between the first abutting surface 211 and the limiting surface 411. Since the pin 30 rotates around the same axis as the rotating shaft 20 (i.e., the axis of the rotating shaft 20), the rotation angle of the pin 30 is the same as the rotation angle of the rotating shaft 20; see also Figure 4 As shown, when the pin 30 rotates clockwise by an angle α from the storage position to the first unfolded position, both the first axis K1 and the second axis K2 rotate by an angle α. If α + β1 is not equal to 180 degrees, then α and β2 are not equal. At this time, the second axis K2 will not coincide with the third axis K3, which will cause the second contact surface 212 to tilt relative to the limiting surface 411, reducing the contact area between the second contact surface 212 and the limiting surface 411, thereby reducing the limiting effect of the limiting component 40 on the rotating shaft 20.

[0043] like Figure 1 and Figure 3As shown, in some embodiments, the clearance opening 12 extends along a preset direction to restrict the pin 30 from rotating along its rotation trajectory. The inner wall of the clearance opening 12 includes a first wall 121. Along the rotation trajectory of the pin 30, the first wall 121 is located on the side of the storage position away from the first unfolded position. When the pin 30 is in the storage position, the pin 30 contacts the first wall 121 to prevent the pin 30 from continuing to rotate away from the first unfolded position, allowing the pin 30 to stop conveniently and stably in the storage position. Furthermore, the first wall 121 is the end position of one end of the clearance opening 12, eliminating the need to provide more rotation space for the pin 30. This allows the length of the clearance opening 12 to be designed to be shorter, thereby reducing the area occupied by the clearance opening 12 on the outer surface of the first housing 10. The preset direction can be selected according to the shape of the first housing 10, enabling the clearance opening 12 to provide rotational limitation for the pin 30, thereby allowing the clearance opening 12 to rotate along the preset rotation trajectory.

[0044] See also Figure 2 and Figure 4 As shown, in some embodiments of this application, the limiting component 40 has a first locking portion 43 on the side facing the rotation shaft 20, and the first abutment surface 211 and the second abutment surface 212 are both provided with second locking portions 22. The first locking portion 43 is used to lock with the second locking portion 22 on the first abutment surface 211 when the plug 30 is in the retracted position, and is also used to lock with the second locking portion 22 on the second abutment surface 212 when the plug 30 is in the first unfolded position, so as to lock the limiting component 40 and the rotation shaft 20. When the first locking portion 43 and the second locking portion 22 are locked, and the plug 30 rotates under the action of external force, the first locking portion 43 and the second locking portion 22 are unlocked.

[0045] Understandably, when the plug 30 rotates to the retracted position, the first locking part 43 on the limiting component 40 can lock with the second locking part 22 on the first abutment surface 211, thereby locking the limiting component 40 with the rotating shaft 20 and fixing the plug 30, allowing the plug 30 to stop more stably in the retracted position. Similarly, when the plug 30 rotates to the first unfolded position, the first locking part 43 on the limiting component 40 can lock with the second locking part 22 on the second abutment surface 212, allowing the plug 30 to stop more stably in the first unfolded position. When the first locking part 43 and the second locking part 22 are locked, when the plug 30 rotates under external force (such as when the user manually rotates the plug 30), it can drive the rotating shaft 20 to rotate, causing the second locking part 22 to unlock from the first locking part 43, allowing the plug 30 to rotate more smoothly.

[0046] In one embodiment, the first locking part 43 includes a locking protrusion, and the second locking part 22 includes a locking groove for engaging with the locking protrusion. When the locking protrusion is engaged with the locking groove, the first locking part 43 and the second locking part 22 are locked together; when the locking protrusion is disengaged from the locking groove, the first locking part 43 and the second locking part 22 are unlocked.

[0047] It should also be noted that in other embodiments, the first locking part 43 and the second locking part 22 can also be locked in other ways. For example, the first locking part 43 may include a first magnetic attractant, and the second locking part 22 may include a first magnetic attractant. The locking of the first locking part 43 and the second locking part 22 is achieved by the magnetic attraction connection between the first magnetic attractant and the second magnetic attractant.

[0048] like Figures 5 to 7 As shown, in some embodiments of this application, the pin 30 also has a second unfolded position on its rotation trajectory. Along the rotation trajectory of the pin 30, the second unfolded position is located on the side of the first unfolded position away from the storage position. That is, the storage position, the first unfolded position and the second unfolded position are arranged sequentially along the rotation trajectory of the pin 30.

[0049] The positioning surface 21 also includes a third abutment surface 213. The first abutment surface 211, the second abutment surface 212, and the third abutment surface 213 are arranged sequentially along the circumference of the rotation shaft 20. When the plug 30 is in the second unfolded position, the limiting component 40 abuts against the third abutment surface 213 to fix the rotation shaft 20. It can be understood that when charging is required, the plug 30 can also be rotated to the second unfolded position. The plug 30 has two working positions, the first unfolded position and the second unfolded position, which allows the angle of the plug 30 to be flexibly adjusted when encountering different types of sockets, so that the plug 30 can be inserted into the socket hole more easily, preventing problems such as unstable plugging, blocking of adjacent sockets, and interference with other plugs.

[0050] In some embodiments, when the pin 30 is in the second extended position, the extension direction of the pin 30 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 213 is perpendicular to the second abutment surface 212, so that the position of the first housing 10 on the socket can be adjusted within a large angle range, preventing the first housing 10 from blocking adjacent sockets and interfering with other plugs around it after the pin 30 is inserted into the socket hole.

[0051] In some embodiments, the inner wall of the clearance opening 12 further includes a second wall. Along the rotation trajectory of the pin 30, the second wall is located on the side of the second unfolded position away from the first unfolded position. When the pin 30 is in the second unfolded position, the pin 30 contacts the second wall to prevent the pin 30 from continuing to rotate away from the first unfolded position, so that the pin 30 can be conveniently and stably stopped at the second bonding position. The second wall is the end position of the clearance opening 12, so there is no need to provide more rotation space for the pin 30, so that the length of the clearance opening 12 can be designed to be shorter.

[0052] In some embodiments, the third abutment surface 213 is also provided with a second locking part 22. When the pin 30 is rotated to the second unfolded position, the first locking part 43 on the limiting component 40 locks with the second locking part 22 on the third abutment surface 213, which can make the pin 30 stop more stably in the second unfolded position.

[0053] In some embodiments, when the pin 30 is in the first unfolded position, the length of the portion of the pin 30 extending outside the first housing 10 is L1; when the pin 30 is in the second unfolded position, the length of the portion of the pin 30 extending outside the first housing 10 is L2, and L2=L1, which makes it more convenient to insert the pin 30 into the socket and can improve the connection strength between the pin 30 and the socket.

[0054] like Figures 8 to 10 As shown, in some embodiments, the positioning surface 21 is located in the middle of the rotating shaft 20. Compared with setting the positioning surface 21 at the end of the rotating shaft 20, in order to prevent the rotating shaft 20 from tilting due to force on one end and causing the rotating shaft 20 to jam, two positioning surfaces 21 need to be set at both ends of the rotating shaft 20, and two sets of limiting components 40 need to be provided for each of the two positioning surfaces 21. This will increase the cost of the pin assembly, and in order to provide space for the two sets of limiting components 40, the first housing 10 needs to have a larger volume, which will increase the volume of the plug. In this embodiment, the positioning surface 21 is set in the middle of the rotating shaft 20, and the overall force on the rotating shaft 20 is more uniform. Only one positioning surface 21 needs to be set, and a set of limiting components 40 needs to be provided for the positioning surface 21. This can reduce the production cost of the pin assembly and reduce the volume of the plug.

[0055] like Figures 7 to 10As shown, in some embodiments, a mounting bracket 50 is provided on the side of the rotating shaft 20 near the clearance opening 12. The mounting bracket 50 is located in the receiving groove 11 and connected to the first housing 10. The rotating shaft 20 is rotatably connected to the mounting bracket 50 so that the rotating shaft 20 is rotatably connected to the first housing 10. The mounting bracket 50 has a first mounting groove 51 with the opening facing the rotating shaft 20, and the limiting component 40 is located in the first mounting groove 51. It can be understood that the rotating shaft 20 is rotatably connected to the first housing 10 through the mounting bracket 50, which makes the connection between the rotating shaft 20 and the first housing 10 more convenient, and eliminates the need to open a shaft hole for mounting the rotating shaft 20 on the first housing 10, so that the outer surface of the first housing 10 can have a larger usable area for mounting devices such as displays. In addition, by accommodating the limiting component 40 in the first mounting groove 51 formed by the mounting bracket 50, the space occupied by the mounting bracket 50 can be fully utilized, making the arrangement of each device in the receiving groove 11 more compact, thereby reducing the volume of the first housing 10 and thus reducing the volume of the pin assembly.

[0056] In some embodiments, the limiting assembly 40 includes a limiting member 41 and an elastic member 42. The limiting member 41 is located within the receiving groove 11 and has a limiting surface 411. The elastic member 42 is located on the side of the limiting member 41 away from the rotating shaft 20. The elastic member 42 is connected to the limiting member 41 and the first housing 10. The elastic member 42 causes the limiting member 41 to abut against the positioning surface 21. The elastic member 42 can be a spring or an elastic block, etc. The elastic member 42 can provide elastic force to the limiting member 41, so that during the rotation of the rotating shaft 20, the limiting member 41 elastically expands and contracts in a direction intersecting the first axial direction X, thereby ensuring that the limiting member 41 always remains in contact with the positioning surface 21, thus providing rotational resistance to the rotating shaft 20 during the rotation of the pin 30. The elastic expansion and contraction direction of the limiting member 41 can be parallel to the second direction B. Of course, the elastic expansion and contraction direction of the limiting member 41 can also be other directions perpendicular to the first axial direction X.

[0057] It should also be noted that, compared to using a spring sheet to provide rotational resistance to the rotating shaft 20, where the first end of the spring sheet is fixed and the second end is raised and in contact with the rotating shaft 20, 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 to the rotating shaft 20, thus shortening the stability and lifespan of the plug. In this embodiment, the elastic element 42 provides elastic force to the limiting element 41. The elastic element 42 does not directly contact the rotating shaft 20, which can prevent the elastic element 42 from rubbing against the rotating shaft 20 and causing wear. Furthermore, both ends of the elastic element 42 are supported, making the elastic force applied by the elastic element 42 to the limiting element 41 more stable, thereby making the motion resistance applied by the limiting element 41 to the rotating shaft 20 more stable, thus improving the stability and lifespan of the plug assembly.

[0058] It should also be noted that the rotation process of the plug 30 from the retracted position to the second unfolded position can be as follows: When the plug 30 is in the retracted position, under the elastic force of the elastic member 42, the limiting surface 411 of the limiting member 41 abuts against the first abutting surface 211, and the locking protrusion of the limiting member 41 inserts into the locking groove on the first abutting surface 211, thereby locking the plug 30 and allowing the plug 30 to be stably stopped in the retracted position. At this time, when the plug 30 is moved to the first unfolded position, the plug 30 rotates under the action of external force, driving the rotating shaft 20 to rotate, causing the locking protrusion to disengage from the locking groove on the first abutting surface 211, and the limiting member 41 and the rotating shaft 20 to unlock. When the plug 30... When rotated to the first unfolded position, the limiting surface 411 of the limiting member 41 abuts against the second abutting surface 212, and the locking protrusion of the limiting member 41 inserts into the locking groove on the second abutting surface 212, thereby locking the pin 30 and allowing the pin 30 to be stably stopped in the storage position. When the pin 30 is continued to be moved to the second unfolded position, the pin 30 rotates under the action of external force, causing the locking protrusion to disengage from the locking groove on the second abutting surface 212. When the pin 30 is rotated to the second unfolded position, the limiting surface 411 of the limiting member 41 abuts against the third abutting surface 213, and the locking protrusion of the limiting member 41 inserts into the locking groove on the third abutting surface 213, thereby locking the pin 30.

[0059] See also Figure 7 As shown, in some embodiments, a limiting post 53 is provided in the first mounting groove 51, and the elastic member 42 is sleeved on the limiting post 53. A limiting groove 412 is provided on the side of the limiting member 41 facing the elastic member 42. The end of the elastic member 42 near the limiting member 41 is located in the limiting groove 412. Both the limiting post 53 and the limiting groove 412 extend along the elastic extension and contraction direction of the limiting member 41, so that the elastic extension and contraction of the elastic member 42 can be more stable, thereby allowing the limiting member 41 to elastically extend and contract in a predetermined direction.

[0060] like Figure 8 and Figure 9 As shown, in some embodiments, the pin assembly further includes a faceplate 60, which is located on the side of the rotating shaft 20 away from the clearance opening 12 and is connected to the first housing 10. The faceplate 60 is used to limit the rotating shaft 20 and prevent the rotating shaft 20 from disengaging from the first housing 10.

[0061] The mounting bracket 50 and the face cover 60 are provided with a positioning post 71, and the other mounting bracket 50 and the face cover 60 are provided with a positioning hole 72 for the positioning post 71 to pass through; the mounting bracket 50 and the face cover 60 are provided with a mounting post 73, and the other mounting bracket 50 and the face cover 60 are provided with a mounting hole 74 for the positioning post 71 to pass through. The positioning of the face cover 60 is achieved by positioning the positioning post 71 and the positioning hole 72, and the installation of the face cover 60 is achieved by cooperating with the mounting post 73 and the mounting hole 74.

[0062] See Figures 9 to 11 As shown in some embodiments of this application, the plug assembly further includes two elastic conductive elements 80. The two elastic conductive elements 80 are located in the receiving groove 11 and connected to the first housing 10. The two elastic conductive elements 80 are respectively located at both ends of the rotating shaft 20 along the first axial direction X. Part of the plug 30 passes through the rotating shaft 20 and contacts the elastic conductive elements 80. The plug 30 can be formed together with the rotating shaft 20 by in-mold injection molding, which can improve the connection strength between the plug 30 and the rotating shaft 20. The elastic conductive elements 80 are used to electrically connect the plug 30 to the electrical control component 91 of the plug, and the elastic conductive elements 80 can undergo elastic deformation, so that the rotating shaft 20 can always maintain contact with the plug 30 during rotation, thereby ensuring the reliability of the electrical connection between the plug 30 and the elastic conductive elements 80.

[0064] In some embodiments, the receiving groove 11 has a mounting opening 13 disposed opposite to the clearance opening 12. The mounting opening 13 is the groove of the receiving groove 11. The elastic conductive element 80 and the rotating shaft 20 and other devices can enter the receiving groove 11 through the mounting opening 13, making the installation of the elastic conductive element 80 and the rotating shaft 20 and other devices more convenient. The elastic conductive element 80 includes a connecting part 81 and a guiding part 82. The connecting part 81 is connected to the first housing 10 and contacts the tail end. The guiding part 82 is located on the side of the connecting part 81 facing the mounting opening 13 and is connected to the connecting part 81.

Then, the rotating shaft 20 can be placed into the receiving slot 11 through the mounting opening 13. The end of the rotating shaft 20 first contacts the guide part 82, and then it is inserted between the two elastic conductive elements 80 along the guide part 82. The guide part 82 can provide installation guidance for the rotating shaft 20, so that the rotating shaft 20 can be inserted between the two elastic conductive elements 80 more smoothly. When installing the rotating shaft 20, the head end of the pin 30 passes through the first clearance opening 12 and exits the receiving slot 11. Then, the face cover 60 can be placed on the mounting bracket 50 through the cooperation of the positioning post 71 and the positioning hole 72. The face cover 60 is fixed by passing the screw through the mounting hole 74 and connecting it with the mounting post 73.

[0066] In some embodiments, a conductive groove 811 is provided on the side of the connecting part 81 facing the rotating shaft 20, and the end of the rotating shaft 20 is inserted into the conductive groove 811 to provide a limit for the rotating shaft 20 and prevent the rotating shaft 20 from separating from the connecting part 81.

[0067] In some embodiments, the elastic conductive element 80 further includes a wiring portion 83, which is located to the side of the connecting portion 81 and connected to the connecting portion 81. The electronic control component 91 can be connected to the wiring portion 83 via a conductive connecting wire, thereby realizing an electrical connection between the connecting portion 81 and the electronic control component 91. The wiring portion 83 may be located to the side of the connecting portion 81 along a third direction C, or it may be located to other sides of the connecting portion 81.

[0068] Secondly, based on the aforementioned pin assembly, this application also provides a plug, such as... Figure 12 and Figure 13 As shown, it includes an electronic control component 91, a second housing 92, and a pin assembly as described in any of the above embodiments. The second housing 92 is disposed opposite to the clearance opening 12. The second housing 92 is connected to the first housing 10 to form a receiving cavity with the first housing 10. The electronic control component 91 is disposed in the receiving cavity and is electrically connected to the pin 30.

[0069] The electronic control component 91 may include a control circuit board, which is electrically connected to the elastic conductive element 80 through a conductive connecting wire, thereby realizing the electrical connection between the electronic control component 91 and the pin 30.
