[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0053] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0054] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0055] The converter usually needs to use the plug assembly on the back of the converter to plug into a fixed wall socket to get power. Users can use the extended socket on the converter. The converter is usually designed to be the same size as the wall socket to pursue better aesthetics and plug-in stability. However, there are many different forms of fixed wall sockets, such as straight five-hole sockets, oblique five-hole sockets, and terraced sockets. Since the plug assembly on the back of the converter is fixed in position, after the converter is plugged into different forms of wall sockets, the relative position relationship between the converter and the wall socket is different, and it is impossible to ensure that the converter and the wall socket are completely aligned, which greatly affects the aesthetics and plug-in stability of the converter.

[0056] Therefore, the present application provides a plug assembly and a converter, wherein the plug assembly has the characteristic of being able to move along a specific track. In a converter using the plug assembly, the position of the plug assembly on the converter can be adjusted so as to adapt to the usage scenarios of different wall sockets and meet the aesthetic effect and plug-in stability of the converter.

[0057] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0058] On the one hand, combined with Figure 1 and Figure 2 As shown, this embodiment provides a plug assembly 100, which includes: an L-pole assembly 2, an N-pole assembly 3 and an E-pole assembly 4, and an insulating shell 1 covering the L-pole assembly 2, the N-pole assembly 3 and the E-pole assembly 4.

[0059] The L-pole assembly 2 includes an L-pole connection point 23, the N-pole assembly 3 includes an N-pole connection point 33, and the E-pole assembly 4 includes an E-pole connection point 43; at least one of the L-pole connection point 23, the N-pole connection point 33, and the E-pole connection point 43 is located on the first side 101 of the insulating housing 1, and the other two are located on the second side 102 of the insulating housing 1, and the second side 102 is arranged opposite to the first side 101. The plug assembly 100 can move along the motion track defined by the first side 101 and the second side 102.

[0060] The plug assembly 100 of the present application is suitable for converter products. The L-pole assembly 2, the N-pole assembly 3 and the E-pole assembly 4 in the plug assembly 100 are simultaneously wrapped in the insulating shell 1, and at least one of the L-pole connection point 23, the N-pole connection point 33 and the E-pole connection point 43 is located on the first side 101 of the insulating shell 1, and the other two are located on the second side 102 of the insulating shell 1, that is, the three connection points are respectively arranged on opposite sides. The plug assembly 100 can move along the motion trajectory defined by the first side 101 and the second side 102. The three connection points are connected to the outside on the first side 101 and the second side 102 respectively, which will not hinder the movement of the plug assembly 100, so that the plug assembly 100 can adjust its position according to different usage scenarios, thereby improving the use range and convenience of converter products.

[0061] In some possible implementations, reference Figure 1 and Figure 2 As shown, the first side 101 and the second side 102 of the insulating housing 1 are distributed along the first direction a, so that the movement trajectory defined by the first side 101 and the second side 102 is shown as the second direction b, and the first direction a and the second direction b are arranged perpendicular to each other. The plug assembly 100 can move along the second direction b to adjust its position on the converter, so that the converter can adapt to a variety of different forms of sockets to meet the needs of a variety of different usage scenarios.

[0062] In some possible implementations, at least one of the L-pole connection point 23, the N-pole connection point 33, and the E-pole connection point 43 is located on the first side 101 of the insulating housing 1, and the other two are located on the second side 102 of the insulating housing 1. Alternatively, one of the three connection points is located on the second side 102, and the other two are located on the first side 101 of the insulating housing 1. The first side 101 and the second side 102 are temporarily defined in this embodiment for the sake of clarity of description. The insulating housing 1 of the plug assembly 100 does not have a strict first side 101 and a second side 102. In theory, the positions of the first side 101 and the second side 102 can be interchanged.

[0063] Exemplarily, the L-pole connection point 23 is located alone on one of the first side 101 and the second side 102, and the N-pole connection point 33 and the E-pole connection point 43 are located at the other of the first side 101 and the second side 102. Alternatively, the N-pole connection point 33 is located alone on one of the first side 101 and the second side 102, and the L-pole connection point 23 and the E-pole connection point 43 are located at the other of the first side 101 and the second side 102. Alternatively, the E-pole connection point 43 is located alone on one of the first side 101 and the second side 102, and the L-pole connection point 23 and the N-pole connection point 33 are located at the other of the first side 101 and the second side 102.

[0064] For example, the L-pole connection point 23 and the N-pole connection point 33 are both located on the first side 101 of the insulating housing 1 , and the E-pole connection point 43 is located alone on the second side 102 of the insulating housing 1 .

[0065] In some embodiments, the insulating shell 1 is an integrated plastic-coated structure. The L-pole component 2, the N-pole component 3 and the E-pole component 4 are wrapped by the insulating shell 1 of the integrated plastic-coated structure, so that the three components are combined into a complete plug assembly 100, which can be moved as a whole.

[0066] Combination Figure 1 and Figure 3 As shown, in some embodiments, the L pole component 2 further includes an L pole pin 21 and an L pole connecting piece 22 , the N pole component 3 further includes an N pole pin 31 and an N pole connecting piece 32 , and the E pole component 4 further includes an E pole pin 41 and an E pole connecting piece 42 .

[0067] The first end 2201 of the L-pole connecting piece 22 is located in the insulating housing 1 , the second end 2202 of the L-pole connecting piece 22 extends to the first side 101 of the insulating housing 1 , the L-pole plug 21 is electrically connected to the first end 2201 , and the L-pole connection point 23 is located on the second end 2202 .

[0068] The third end 3201 of the N-pole connecting piece 32 is located in the insulating housing 1 , the fourth end 3202 of the N-pole connecting piece 32 extends to the first side 101 or the second side 102 of the insulating housing 1 , the N-pole plug 31 is electrically connected to the third end 3201 , and the N-pole connection point 33 is located on the fourth end 3202 .

[0069] The fifth end 4201 of the E-pole connecting piece 42 is located in the insulating housing 1 , the sixth end 4202 of the E-pole connecting piece 42 extends to the first side 101 or the second side 102 , the E-pole plug 41 is electrically connected to the fifth end 4201 , and the E-pole connection point 43 is located on the sixth end 4202 .

[0070] In the plug assembly 100 of this embodiment, in the L-pole assembly 2, the N-pole assembly 3 and the E-pole assembly 4, the plugs and the connection points are respectively arranged at the two ends of the connecting piece, the plugs realize the electrical connection between the plug assembly 100 and the socket, and the connection points realize the electrical connection between the plug assembly 100 and the plug sleeve assembly 08 in the converter. Since the positions of the three plugs are relatively fixed, the connection points corresponding to the plugs can be extended to the corresponding first side 101 or second side 102 through the connecting piece, so that at least one of the L-pole connection point 23, the N-pole connection point 33 and the E-pole connection point 43 is located on the first side 101 of the insulating housing 1, and the other two are located on the second side 102 of the insulating housing 1.

[0071] In some possible implementations, reference Figure 3 The insulating housing 1 is provided with three pin extension holes 11, which are used to accommodate the L-pole pin 21, the N-pole pin 31 and the E-pole pin 41 respectively.

[0072] In some other possible implementations, when the insulating shell 1 is an integrated plastic-coated structure, in order to prevent the L-pole pin 21, the N-pole pin 31 and the E-pole pin 41 from jumping in position during the plastic-coating process, three process holes 13 are provided on the insulating shell 1 for fixing the position of the pins during the plastic-coating process.

[0073] In some other possible implementations, at least one of the L-pole plug 21 , the N-pole plug 31 and the E-pole plug 41 is provided with a gripping structure 211 , such as a hole, a groove or a notch opened on the surface of the plug.

[0074] Combination Figure 1 and Figure 3 As shown, in some embodiments, the L-pole plug 21 and the N-pole plug 31 are arranged close to the second side 102, and the E-pole plug 41 is arranged close to the first side 101. In this way, the L-pole plug 21, the N-pole plug 31 and the E-pole plug 41 can be arranged in a herringbone shape, which can be suitable for most three-hole sockets.

[0075] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the E-pole connecting piece 42 extends to the second side 102 along the middle of the L-pole plug 21 and the N-pole plug 31. The E-pole plug 41 of this embodiment is arranged in the middle of the L-pole plug 21 and the N-pole plug 31, and the E-pole connecting piece 42 extends to the second side 102 along the middle of the L-pole plug 21 and the N-pole plug 31, thereby ensuring that the E-pole connection point 43 is located on the second side 102 of the insulating housing 1 and in the middle of the L-pole plug 21 and the N-pole plug 31, which is conducive to improving the convenience and stability of the electrical connection of the E-pole connection point 43.

[0076] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the L-pole connecting piece 22 and the N-pole connecting piece 32 extend to the first side 101 along both sides of the E-pole plug 41, respectively. The L-pole plug 21 and the N-pole plug 31 of this embodiment are arranged on both sides of the E-pole plug 41, and the L-pole connecting piece 22 and the N-pole connecting piece 32 extend from both sides of the E-pole plug 41 to the first side 101, respectively, which can ensure that the L-pole connection point 23 and the N-pole connection point 33 are located on the first side 101 of the insulating housing 1, and are respectively located at both ends of the E-pole plug 41, which is conducive to improving the convenience and stability of the electrical connection of the E-pole connection point 43.

[0077] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, at least one of the L-pole connecting plate 22 , the N-pole connecting plate 32 and the E-pole connecting plate 42 is provided with a concave-convex structure 223 , and the concave-convex structure 223 is located in the insulating shell 1 .

[0078] By utilizing the concavo-convex structure 223 provided on the connecting piece, the injection molding reliability of the connecting piece and the insulating housing 1 can be improved, and parallel movement of the connecting piece and the insulating housing 1 can be prevented, thereby ensuring the structural reliability of the plug assembly 100.

[0079] Exemplarily, the L-pole connecting piece 22 is provided with a concavo-convex structure 223; or, the N-pole connecting piece 32 is provided with a concavo-convex structure 223; or, the E-pole connecting piece 42 is provided with a concavo-convex structure 223. In another exemplary embodiment, the L-pole connecting piece 22 and the N-pole connecting piece 32 are provided with a concavo-convex structure 223 respectively; or, the L-pole connecting piece 22 and the E-pole connecting piece 42 are provided with a concavo-convex structure 223 respectively; or, the N-pole connecting piece 32 and the E-pole connecting piece 42 are provided with a concavo-convex structure 223 respectively. In another exemplary embodiment, the L-pole connecting piece 22, the N-pole connecting piece 32 and the E-pole connecting piece 42 are provided with a concavo-convex structure 223 respectively.

[0080] Optionally, the concavo-convex direction of the concavo-convex structure 223 is perpendicular to the plane where the first direction a and the second direction b are located.

[0081] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, at least one of the L-pole connection point 23 , the N-pole connection point 33 and the E-pole connection point 43 is a contact connection position, and the contact connection position is provided with a folding surface 221 .

[0082] In this embodiment, at least one of the three connection points can be designed as a contact connection position. By utilizing the contact connection position, the connection point can achieve electrical contact with the external circuit structure, thereby ensuring that the plug assembly 100 can be electrically connected to the external circuit structure without hindrance during movement or when moved to any position, thereby ensuring the electrical connection stability between the plug assembly 100 and other circuit structures in the converter.

[0083] Exemplarily, the L pole connection point 23 is set as a contact connection position; or, the N pole connection point 33 is set as a contact connection position; or, the E pole connection point 43 is set as a contact connection position. In another exemplary embodiment, the L pole connection point 23 and the N pole connection point 33 are respectively set as contact connection positions; or, the L pole connection point 23 and the E pole connection point 43 are respectively set as contact connection positions; or, the N pole connection point 33 and the E pole connection point 43 are respectively set as contact connection positions. In another exemplary embodiment, the L pole connection point 23, the N pole connection point 33 and the E pole connection point 43 are respectively set as contact connection positions.

[0084] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, at least one of the L-pole connection point 23, the N-pole connection point 33 and the E-pole connection point 43 is a contact connection position, and the contact connection position is provided with a horizontal plane 421, and a raised moving contact is provided on the side of the horizontal plane 421 facing away from the L-pole plug 21, the N-pole plug 31 or the E-pole plug 41.

[0085] When at least one of the L-pole connection point 23, the N-pole connection point 33 and the E-pole connection point 43 is a contact connection position, a horizontal plane 421 is set at the contact connection position, and a raised moving contact is set on the side of the horizontal plane 421 facing away from the pin. When the plug assembly 100 is matched with the converter, since the plug assembly 100 needs to be arranged on the back of the converter and the pin is arranged toward the back of the converter, the moving contact faces the front of the converter, so that it can abut against the static contact in the converter, which is conducive to reducing the design difficulty of the electrical connection structure between the plug assembly 100 and the converter and improving the stability of the electrical connection between the plug assembly 100 and the converter.

[0086] Combination Figure 2As shown, in some embodiments, the L-pole connection point 23 and the N-pole connection point 33 are located on the same side of the insulating housing 1, and both the L-pole connection point 23 and the N-pole connection point 33 are contact connection positions; the distances between the L-pole connection point 23 and the N-pole connection point 33 and the insulating housing 1 are not equal. Therefore, the L-pole connection point 23 and the N-pole connection point 33 are staggered along the first direction a, and the two corresponding static contacts also need to be staggered along the first direction a, so as to avoid position interference between the two static contacts.

[0087] Combination Figure 2 As shown, in some embodiments, the L-pole connection point 23 and the N-pole connection point 33 are located on the same side of the insulating housing 1, and both the L-pole connection point 23 and the N-pole connection point 33 are contact connection points; one of the L-pole connection point 23 and the N-pole connection point 33 extends outward in the horizontal direction to lengthen the horizontal spacing between the L-pole connection point 23 and the N-pole connection point 33. Thus, the L-pole connection point 23 and the N-pole connection point 33 are staggered in position along the first direction a, and the two corresponding static contacts also need to be staggered in position along the first direction a, so as to avoid position interference between the two static contacts.

[0088] Combination Figure 2 , 4 5, in some embodiments, the vertical distance between the second end 2202 and the first end 2201 is L1, and the vertical distance between the fourth end 3202 and the third end 3201 is L2, wherein L1<L2. Thus, the L-pole connection point 23 and the N-pole connection point 33 are staggered along the first direction a, and the two corresponding static contacts also need to be staggered along the first direction a, so as to avoid position interference between the two static contacts.

[0089] Combination Figure 2 and Figure 5 As shown, in some embodiments, the N-pole connecting piece 32 is provided with an avoidance bend 321, which is recessed in a direction away from the L-pole connecting point 23, and the avoidance bend 321 is used to avoid the L-pole static contact contacting the L-pole connecting point 23. Fig. 9 By providing an avoidance bend 321 on the N-pole connecting piece 32 , the position of the L-pole static contact corresponding to the L-pole connecting point 23 can be avoided.
