[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0056] The present application embodiment provides a multi-country converter, such as Figure 1 As shown, the multinational converter includes a socket assembly 100 and a plug assembly 200; the socket assembly 100 includes a first shell 11, and a socket assembly 12 installed on the first shell 11, the socket assembly 12 is used to provide an E-pole contact 1211, an L-pole contact 1221 and an N-pole contact 1231; the plug assembly 200 includes a second shell 21, and a pin assembly 22 installed on the second shell 21, the second shell 21 is detachably connected to the first shell 11, the pin assembly 22 can contact with the socket assembly 12, so that the plug assembly 200 and the socket assembly 100 are electrically connected, wherein the contact between at least one pin in the pin assembly 22 and the corresponding contact is elastic abutment.

[0057] Therefore, when the multinational converter provided in the embodiment of the present application is used, a suitable plug assembly 200 can be selected according to actual needs and installed on the socket assembly 100. Since the first shell 11 and the second shell 21 are detachably connected, the currently installed plug assembly 200 can be removed from the socket assembly 100 when the use is completed or a new plug assembly 200 needs to be replaced; the plug assembly 200 has a two-pole plug or a three-pole plug, and the socket assembly 100 is provided with a socket assembly 12 inside to provide an E-pole contact 1211, an L-pole contact 1221 and an N-pole contact 1231. After the socket assembly 100 and the plug assembly 200 are assembled, each of the plugs of the plug assembly 200 contacts the corresponding contacts respectively, thereby achieving electrical conduction. Therefore, the socket assembly 12 in the multinational converter provided in the embodiment of the present application can provide an E-pole contact 1211, which can be electrically connected with the E-pole plug in the plug assembly 200 to provide effective grounding protection. When the electrical appliance is plugged into the multinational converter, it has better electrical safety.

[0058] In some embodiments of the present application, Figure 2As shown, the first shell wall 111 of the first shell 11 is provided with a first opening 1111, a second opening 1112 and a third opening 1113 at intervals. The shapes and opening sizes of the first opening 1111, the second opening 1112 and the third opening 1113 are designed according to actual needs and can be the same or different. Figure 2 As shown in , the shape of the first opening 1111 is rectangular, and the shapes of the second opening 1112 and the third opening 1113 are circular; the opening area of ​​the first opening 1111 is greater than the opening area of ​​the second opening 1112, and the opening area of ​​the third opening 1113 is equal to the opening area of ​​the second opening 1112. Alternatively, in other examples, the shapes of the first opening 1111, the second opening 1112, and the third opening 1113 can all be rectangular, and the opening areas are equal.

[0059] The first shell wall 111 is a shell wall for assembling the plug assembly 200. Generally speaking, the first shell wall 111 and the panel of the socket assembly 100 (i.e., the second shell wall 112, such as Fig. 9 However, in some embodiments, for example, when the first housing 11 of the socket assembly 100 is a polyhedron or an irregular shape, the first housing wall 1111 and the panel of the socket assembly 100 may not be opposite to each other.

[0060] The socket assembly 12 includes an E-pole socket 121, an L-pole socket 122, and an N-pole socket 123, which are exposed from the first opening 1111, the second opening 1112, and the third opening 1113, respectively, to contact the E-pole plug pin, the L-pole plug pin, and the N-pole plug pin in the plug assembly 200, respectively, to achieve electrical conduction. It should be noted that in the embodiment of the present application, any socket is "exposed" from the corresponding opening, which includes the situation that the socket is completely located in the first shell 11, that is, completely located on the inner side of the opening, and the human eye can see at least a part of the socket when looking from the direction facing the opening; it also includes the situation that at least a part of the socket extends from the inner side of the opening through the opening to the outer side of the opening, so as to be located outside the first shell 11.

[0061] Among them, the part of the E-pole socket 121 exposed from the first opening 1111 is elastic in the axial direction of the first opening 1111; and / or, the part of the L-pole socket 122 exposed from the second opening 1112 is elastic in the axial direction of the second opening 1112; and / or, the part of the N-pole socket 123 exposed from the third opening 1113 is elastic in the axial direction of the third opening 1113. It should be understood that the axial direction of any opening refers to the extension direction of the central axis of the opening, and the central axis is perpendicular to the opening plane of the opening. By making at least one of the E-pole socket 121, the L-pole socket 122 and the N-pole socket 123 elastic, it can be achieved that after the socket assembly 100 is connected to the plug assembly 200, the above-mentioned sockets and the corresponding pins are elastically abutted, thereby ensuring contact reliability and avoiding circuit disconnection or grounding protection failure.

[0062] In some embodiments of the present application, Figure 3 As shown, the E-pole socket 121 includes a first connecting portion 1212 and a first clamping portion 1213, the first connecting portion 1212 includes at least two connecting segments connected by bending, a first connecting segment 12121 of the at least two connecting segments is connected to the first clamping portion 1213, and a second connecting segment 12122 of the at least two connecting segments is exposed from the first opening 1111.

[0063] It should be noted that, in the embodiment of the present application, the second connecting section 12122 is exposed from the first opening 1111, which includes the situation that the second connecting section 12122 is completely located in the first shell 11, and the human eye can see at least a portion of the second connecting section 12122 when looking from the direction facing the first opening 1111; it also includes the situation that at least a portion of the second connecting section 12122 passes through the first opening 1111 and extends to the outside of the first shell 11.

[0064] Optionally, the E-pole socket 121 can be formed by bending a conductive metal strip multiple times, and each connecting segment on the E-pole socket 121 can be elastically deformed, so that when the E-pole plug on the plug assembly 200 elastically abuts against the second connecting segment 12122 to electrically connect the socket assembly 100 and the plug assembly 200, the reliability of electrical contact can be ensured. Exemplarily, the conductive metal strip is a copper strip.

[0065] Optionally, the length of the second connecting section 12122 for contacting and mating with the E-pole plug on the plug assembly 200 is greater than the length of the first connecting section 12121 connected to the first clamping portion 1213. The length direction of the first connecting section 12121 is parallel to the length direction of the second connecting section 12122 and to the length direction of the first opening 1111, and the length direction of the first opening 1111 is perpendicular to the line connecting the center of the second opening 1112 and the center of the third opening 1113.

[0066] Therefore, compared with the case where the E-pole plug is directly matched with the first connecting section 12121, this embodiment is equivalent to increasing the length of the portion of the E-pole socket 121 that can contact and match with the E-pole plug, thereby enriching the types of plug assemblies 200 that the socket assembly 100 can adapt to. For example, in standard plugs of various countries, the distance between the E-pole plug and the L and N-pole pins of the German standard / French standard plug is smaller, and the distance between the E-pole pin and the L and N-pole pins of the British standard plug is larger. The multi-country converter of this embodiment adopts the above-mentioned socket assembly 100, which is suitable for the conversion of both German standard / French standard sockets and British standard sockets, and has better versatility. Continue to see Figure 3 In some embodiments of the present application, at least two connecting segments of the first connecting portion 1212 further include a third connecting segment 12123, and the third connecting segment 12123 is connected between the first connecting segment 12121 and the second connecting segment 12122. The length direction of the third connecting segment 12123 is perpendicular to the length direction of the first connecting segment 12121 and to the length direction of the second connecting segment 12122. The length directions of the first connecting segment 12121 and the second connecting segment 12122 are the same and are positioned oppositely.

[0067] Compared to the solution of directly connecting the first connecting segment 12121 and the second connecting segment 12122, the third connecting segment 12123 is arranged between the first connecting segment 12121 and the second connecting segment 12122 in this embodiment, which can make it easier for the first connecting portion 1212 to undergo elastic deformation, so that when the socket assembly 100 is connected to the plug assembly 200, the second connecting segment 12122 can provide a greater elastic force to the E-pole pin, thereby further improving the electrical contact reliability.

[0068] Optionally, the length of the third connecting segment 12123 is smaller than that of the first connecting segment 12121 and smaller than that of the second connecting segment 12122. On the one hand, this enables the third connecting segment 12123 to elastically deform when pressed and is less likely to yield. On the other hand, it can prevent the first connecting portion 1212 from occupying too much space in the first shell 11, thereby helping to miniaturize the multinational converter.

[0069] At the same time, since the second connecting section 12122 is the longest, on the one hand, the second connecting section 12122 can have better elasticity, and on the other hand, the second connecting section 12122 can be adapted to the E-pole pins at different positions on the plug assembly 200.

[0070] In some embodiments of the present application, Figure 3As shown, the at least two connecting segments also include a fourth connecting segment 12124, which is connected to an end of the second connecting segment 12122 away from the third connecting segment 12123, and the third connecting segment 12123 and the fourth connecting segment 12124 have the same length direction and are positioned oppositely.

[0071] like Figure 4 and Figure 5 As shown, the second connecting section 12122 is located in the first opening 1111 , and the third connecting section 12123 and the fourth connecting section 12124 have gaps 1114 with the hole walls on opposite sides of the first opening 1111 .

[0072] Since there are gaps 1114 between the third connecting section 12123 and the fourth connecting section 12124 of the E-pole socket 121 and the inner wall of the first opening 1111, the E-pole socket 121 can be allowed to move in position due to elastic deformation in the first opening 1111, thereby ensuring the existence of interaction force with the abutting E-pole pin.

[0073] In some embodiments of the present application, Figure 2 As shown, in the specified direction, the length of the first opening 1111 is greater than the length of the second opening 1112, and greater than the length of the third opening 1113. The specified direction is perpendicular to the line connecting the center of the first opening 1111 and the center of the second opening 1112, and the specified direction can also be regarded as the length direction of the first opening 1111.

[0074] Generally speaking, in order to adapt to the positions of the E-pole plug, the L-pole plug and the N-pole plug in the plug assembly 200, the first opening 1111, the second opening 1112 and the third opening 1113 are usually arranged in a triangular shape. By setting the length of the first opening 1111 to be relatively large, the E-pole plug at different heights on the plug assembly 200 can be adapted. It should be noted that in some examples, the shape of the first opening 1111, the second opening 1112 or the third opening 1113 may be circular, for example, Figure 3 As shown in , the second opening 1112 and the third opening 1113 are circular in shape. In this case, the length of the circular opening in a specified direction refers to the diameter of the circular opening.

[0075] Optionally, the length of the first opening 1111 is 2-5 times the length of the second opening 1112; or 2-5 times the length of the third opening 1113. Exemplarily, the length of the second opening 1112 is equal to the length of the third opening 1113, and the length of the first opening 1111 is 3 or 4 times the length of the second opening 1112.

[0076] Optionally, the length of the first opening 1111 is 30%-70% of the length of the first shell 11, and the length direction of the first shell 11 is the same as the length direction of the first opening 1111. Exemplarily, the length of the first opening 1111 is 40%, 50% or 60% of the length of the first shell 11.

[0077] Figures 6 to 10 A socket assembly 12 provided in an embodiment of the present application is shown, wherein an L-pole socket 122 and an N-pole socket 123 are respectively located on both sides of an E-pole socket 121. The structural features of the socket assembly 12 are described below in conjunction with the accompanying drawings.

[0078] In some embodiments of the present application, Figure 7 As shown, the L-pole plug sleeve 122 includes a first plug sleeve 1222, a first conductive member 1223 and a first elastic member 1224; the first plug sleeve 1222 is located inside the first shell 11 and is electrically connected to the first conductive member 1223; the first conductive member 1223 is elastically connected to the first plug sleeve 1222 through the first elastic member 1224, and one end of the first conductive member 1223 away from the first plug sleeve 1222 extends out of the second opening 1112.

[0079] Therefore, if Figure 1 As shown, one end of the first conductive member 1223 extends out from the second opening 1112 to form an L-pole contact 1221, which is used to contact and cooperate with the L-pole plug in the plug assembly 200. Among them, the first elastic member 1224 is a conductor and has conductivity. After the current on the L-pole plug flows to the first conductive member 1223, it flows to the first plug set 1222 through the first elastic member 1224 that is in contact and conductive with the first conductive member 1223, so as to provide power to the outside. Under the elastic force provided by the first elastic member 1224, the first conductive member 1223 maintains elastic contact with the L-pole plug, so it has good contact reliability and improves the stability of the circuit.

[0080] Optionally, continue to see Figure 7 The first conductive member 1223 includes a first conductor portion 12231 and a first stop portion 12232. One end of the first conductor portion 12231 is movably connected to the first plug-in kit 1222, and the other end of the first conductor portion 12231 passes through the second opening 1112. The first stop portion 12232 is located inside the first shell 11 and connected to the middle part of the first conductor portion 12231. The first stop portion 12232 is used to prevent the first conductor portion 12231 from escaping from the first shell 11 through the second opening 1112. The first elastic member 1224 is sleeved between the first plug-in kit 1222 and the first stop portion 12232 and is in an elastically compressed state.

[0081] In some embodiments of the present application, Figure 7As shown, the L-pole socket 122 includes a first adapter 1225, which is used to establish a reliable electrical connection between the first socket set 1222 and the first conductive member 1223, while reducing the difficulty of installing the first conductive member 1223 on the first socket set 1222, thereby improving the assembly efficiency of the L-pole socket 122.

Specifically, as Figure 8 As shown, a second plug-in portion 12324 is formed on the second plug-in kit 1232. After the second adapter 1235 is plugged into the second plug-in portion 12324, the second plug-in portion 12324 can apply a clamping force to the second adapter 1235, thereby realizing the plug-in fit between the second adapter 1235 and the second plug-in kit 1232; at the same time, the second conductive member 1233 is movably connected to an end of the second adapter 1235 away from the second plug-in portion 12324, for example, the second conductive member 1233 is connected to an axial structure, a hole structure is formed on the second adapter 1235, and the axial second conductive member 1233 is inserted into the hole structure on the second adapter 1235, and cooperates with the gap 1114 of the hole structure to realize axial movement.
