[0023] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only 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.

[0024] In the related art, the conversion plug of the multi-country travel charger needs to integrate the pins of multiple different countries, so the overall size of the plug is large, which is not convenient for users to carry with them when traveling.

[0025] For the above situation, please see Figure 1-Figure 3 The present application proposes a plug 1, comprising a main body 10, a first pin assembly 20 and a second pin assembly 30, wherein the first pin assembly 20 is mounted on the main body 10, the first pin assembly 20 comprises a first pin 21, the main body 10 and the first pin assembly 20 form a complete plug 1, and the first pin 21 can be plugged into a socket for power supply operation; the second pin assembly 30 is detachably connected to the first pin assembly 20, and the second pin assembly 30 comprises a shell 32 and a second pin 31 disposed on the shell 32. The first pin 21 and the second pin 31 are two different types of pins, for example, the first pin 21 is a flat pin of smaller size such as Chinese standard, American standard or Japanese standard, and the second pin 31 is a pin of larger size such as European standard or British standard.

[0026] Among them, the second pin assembly 30 has a use state. When the first pin 21 does not match the socket, the second pin assembly 30 can be installed on the first pin assembly 20. At this time, the second pin assembly 30 is in a use state. The second pin assembly 30 is plugged and matched with the first pin assembly 20 along the first direction L1, so that the plug 1 is replaced from the first pin 21 to the second pin 31, and the first pin 21 is electrically connected to the second pin 31, so that the second pin 31 can be inserted into the socket for power-taking operation, that is, the first direction L1 is the plugging direction of the first pin assembly 20 and the second pin assembly 30.

[0027] like Figure 4-Figure 6 As shown, a slot 22 is provided on the first pin assembly 20, and the second pin assembly 30 also includes a snap-in component 34, which is disposed on the housing 32. When the second pin assembly 30 is in use, the snap-in component 34 is snapped into the slot 22 to fix the second pin assembly 30 on the first pin assembly 20.

[0028] It can be understood that when the second pin assembly 30 is in use, the first pin 21 is inserted into the socket 321 on the shell 32, and at the same time, the clamping piece 34 on the shell 32 is clamped in the slot 22, that is, there is a connection relationship between multiple parts of the first pin assembly 20 and the second pin assembly 30, and the connection includes the plugging of the first pin assembly 20 and the second pin assembly 30, the clamping of the clamping piece 34 and the slot 22, etc., so as to improve the connection strength between the two, that is, make the connection between the first pin assembly 20 and the second pin assembly 30 more secure.

[0029] Among them, Figure 3 As shown, the first pin assembly 20 includes a cover body 24, and the first pin 21 is arranged on the top of the cover body 24. The present embodiment does not specifically limit the arrangement positions of the card slot 22 and the card connector 34. For example, the card slot 22 can be located at the top of the cover body 24, and the card connector 34 is located on the side of the shell 32 away from the second pin 31, or the card connector 34 and the second pin 31 are respectively located on two adjacent side surfaces of the shell 32. When the second pin assembly 30 is in use, the shell 32 contacts the top of the cover body 24, and at the same time, the card connector 34 enters the card slot 22 and is engaged with it; for another example, the card slot 22 is located on the side of the cover body 24, and the card connector 34 is also located on the side of the shell 32. When the second pin assembly 30 is in use, the shell 32 contacts the top of the cover body 24, and the card connector 34 can enter the card slot 22 and be engaged with it through elastic deformation or external force. In some alternative structures, the clamping member 34 may also be disposed on the cover 24 of the first pin assembly 20 , and the clamping slot 22 may be correspondingly disposed on the housing 32 of the second pin assembly 30 .

[0030] Specifically, the second pin assembly 30 may include multiple pins, and the second pins 31 in the multiple second pin assemblies 30 are all different types of pins. Users can carry different second pin assemblies 30 according to their needs, so that the plug 1 can be applied to more power usage scenarios. The embodiment of the present application does not limit the specific connection method between the first pin assembly 20 and the second pin assembly 30. For example, the connection method between the second pin assembly 30 and the first pin assembly 20 may include at least one of snap-on, plug-in, and magnetic attraction.

[0031] It should be noted that the embodiment of the present application provides a second pin assembly 30 that can be installed separately, so that the plug 1 can switch between the first pin 21 and the second pin 31 at any time, thereby improving the universality of the plug 1. At the same time, the second pin assembly 30 can be removed from the first pin assembly 20 to facilitate the storage of the plug 1, thereby reducing the overall volume of the plug 1 and making it convenient to carry outside.

[0032] See also Figure 1 In some embodiments of the present application, the first pin assembly 20 also includes a mounting base 23, the first pin 21 is arranged on the mounting base 23, and the mounting base 23 is rotatably connected to the main body 10; the second pin assembly 30 is detachably connected to the mounting base 23, and when the second pin assembly 30 is in use, the mounting base 23 can drive the second pin assembly 30 to rotate relative to the main body 10.

[0033] Specifically, when the first pin 21 is used, the mounting seat 23 can be rotated according to the size of the available space on the socket, so as to control the relative direction of the mounting seat 23 and the main body 10, thereby reducing the interference of the main body 10 with other plugs on the socket. The second pin assembly 30 is connected to the mounting seat 23, so that the mounting seat 23 drives the second pin assembly 30 to rotate when rotating. Among them, a mounting groove can be provided on the main body 10, and the mounting seat 23 is arranged in the mounting groove, and the mounting seat 23 is rotatably connected to the inner side wall of the mounting groove. The mounting seat 23 can rotate relative to the inner side wall of the mounting groove. The mounting groove provides a setting foundation and installation space for the mounting seat 23 to reduce the interference of external wire winding on the rotation of the mounting seat 23.

[0034] See also Figure 2-Figure 4 In some embodiments of the present application, a socket 321 is provided on the housing 32 , and the first pin 21 is plugged into the socket 321 , that is, the socket 321 is used for the first pin 21 to be inserted.

[0035] Specifically, when the second pin assembly 30 is in use, the first pin 21 is inserted into the socket 321, that is, a portion of the first pin 21 enters the interior of the housing 32 from the socket 321, and is conductively connected to the second pin 31 inside the housing 32. The housing 32 can provide protection for the conductive connection between the first pin 21 and the second pin 31 to reduce the occurrence of leakage. The embodiment of the present application does not specifically limit the location of the socket 321. For example, the socket 321 can be located on the side of the housing 32 away from the second pin 31. After the first pin 21 is inserted from the socket 321, the orientation of the first pin 21 is the same as that of the second pin 31. For another example, the socket 321 and the second pin 31 are respectively located on two adjacent sides of the housing 32. After the first pin 21 is inserted from the socket 321, the orientation of the first pin 21 is perpendicular to that of the second pin 31.

[0036] For further information, please see Figure 2-Figure 4 In some embodiments of the present application, the second pin assembly 30 also includes a conductive member 33, which is disposed in the housing 32 and is in conductive contact with the second pin 31. The conductive member 33 includes a clamping portion 331 corresponding to the socket 321.

[0037] Specifically, when the second pin assembly 30 is in use, the first pin 21 passes through the insertion hole 321 and is clamped in the clamping portion 331. It is easy to understand that the first pin 21 is clamped in the clamping portion 331, which can reduce the shaking of the first pin 21 and ensure that the first pin 21 and the second pin 31 can be in stable contact and conduction. Exemplarily, the clamping portion 331 may include a conductive spring sheet. After the first pin 21 passes through the insertion hole 321, the first pin 21 is inserted into the clamping portion 331. At this time, the first pin 21 applies a force to the conductive spring sheet, which deforms and clamps the first pin 21, so that the first pin 21 is in close contact with the conductive spring sheet, reducing the possibility of the first pin 21 loosening and improving the reliability of the electrical connection. Figure 4 As shown, the conductive member 33 may further include a contact portion 332 arranged at an angle with the clamping portion 331 , the contact portion 332 having a through hole, and the end of the second pin 31 may penetrate the through hole and be in conductive contact with the contact portion 332 .

[0038] Illustratively, a guiding bevel is provided at one end of the clamping portion 331 close to the socket 321. When the first pin 21 is inserted into the clamping portion 331, the end of the first pin 21 first contacts the guiding bevel. Subsequently, the end of the first pin 21 can slide along the guiding bevel until it enters the clamping portion 331. The guiding bevel provides guidance for the first pin 21.

[0039] See also Figure 3-Figure 5 In some embodiments of the present application, in the second direction L2 which is at an angle to the first direction L1, the first direction L1 is the plugging direction of the first pin assembly 20 and the second pin assembly 30, and the clamping member 34 is movably connected with the housing 32 along the second direction L2; the second pin assembly 30 further includes a pressing member 35, which is slidably connected with the housing 32 along the third direction L3, and the pressing member 35 is linked with the clamping member 34. The first direction L1, the second direction L2 and the third direction L3 can be arranged at an angle to each other, and for example, the first direction L1, the second direction L2 and the third direction L3 are perpendicular to each other.

[0040] Specifically, the user can control the movement of the clamping member 34 by applying a force along the third direction L3 to the pressing member 35, that is, the pressing member 35 is acted upon by an external force, the pressing member 35 slides along the third direction L3 relative to the housing 32, and the pressing member 35 drives the clamping member 34 to move along the second direction L2, thereby achieving the purpose of engaging or releasing the clamping member 34 from the card slot 22. The pressing member 35 can be connected to the clamping member 34 so that the pressing member 35 drives the clamping member 34 to move, or the pressing member 35 can also abut against the clamping member 34, and a force is applied to the clamping member 34 by the pressing member 35 to drive the clamping member 34 to move.

[0041] For example, Figure 5-Figure 6 As shown, a first step structure 221 is provided on the inner wall of the slot 22, and a second step structure 344 is provided on the clamping piece 34. When the second pin assembly 30 moves along the first direction L1, the second pin assembly 30 gradually approaches the first pin assembly 20. When the clamping piece 34 is clamped with the slot 22, the second step structure 344 and the first step structure 221 are arranged along the first direction L1, and the second step structure 344 buckles the first step structure 221. When the clamping piece 34 is unclamped from the slot 22, the second step structure 344 is disengaged from the first step structure 221 in a direction perpendicular to the first direction L1, so that the second step structure 344 is disengaged from the second step structure 344 by force contact. At this time, the clamping piece 34 can be disengaged from the slot 22, so that the first pin assembly 20 can be withdrawn from the second pin assembly 30.

[0042] In some embodiments, Figure 3-Figure 4 As shown, the second pin assembly 30 may include two pressing members 35 and two clamping members 34, and the pressing members 35 and the clamping members 34 are linked and connected in a one-to-one correspondence. The two clamping members 34 are located in the same plane as the jack 321, and the two clamping members 34 are arranged on opposite sides of the jack 321 in the second direction L2, and the two pressing members 35 are arranged on opposite sides of the shell 32 in the third direction L3. When the first pin 21 is inserted into the jack 321, the user applies a force along the third direction L3 to the pressing members 35 on both sides of the shell 32, so that the pressing members 35 drive the clamping members 34 to slide along the second direction L2, so that the clamping members 34 are clamped with the card slot 22, and the second pin assembly 30 becomes in use.

[0043] For further information, see Figure 7-Figure 8 In some embodiments of the present application, the clamping member 34 includes a first part 341 and a second part 342 that are arranged opposite to each other, the first part 341 and the second part 342 are arranged independently of each other, and the first part 341 and the second part 342 are both slidably connected to the housing 32 in the second direction L2.

[0044] The pressing member 35 includes two connected linkage parts 351, and the two linkage parts 351 are located on the opposite sides of the clamping member 34 in the second direction L2, wherein the first part 341 and the second part 342 are located between the two linkage parts 351. When the pressing member 35 slides along the third direction L3 relative to the shell 32, the linkage part 351 can drive the first part 341 and the second part 342 to move closer to each other or away from each other along the second direction L2.

[0045] Further, such as Figure 5-Figure 8 As shown, the first part 341 and the second part 342 both include a snap-on structure 345, which is located on the side of the shell 32 facing the first pin assembly 20. When the first part 341 and the second part 342 move toward each other along the second direction L2, the snap-on structure 345 can be separated from the slot 22. When the first part 341 and the second part 342 move away from each other along the second direction L2, the snap-on structure 345 can be snap-on with the slot 22. Specifically, the second step structure 344 is located on the clamping structure 345. In the second direction L2, when the first part 341 and the second part 342 slide toward each other, the two clamping structures 345 on the first part 341 and the second part 342 get closer and closer, that is, the distance between the two clamping structures 345 is reduced, and the space occupied by the two clamping structures 345 is reduced. The first step structure 221 and the second step structure 344 are disengaged, so that the clamping connection between the clamping structure 345 and the slot 22 is released, and the two clamping structures 345 can be inserted into or leave the slot 22 from the opening of the slot 22, thereby making the first pin 22 The component 20 can be inserted into the second pin component 30 or withdrawn from the second pin component 30; when the first part 341 and the second part 342 slide back to back, the two clamping structures 345 on the first part 341 and the second part 342 become farther and farther apart, that is, the distance between the two clamping structures 345 increases, and the space occupied by the two clamping structures 345 increases. The second step structure 344 on the clamping structure 345 can abut against the first step structure 221 of the slot 22 to clamp the two clamping structures 345 in the slot 22, thereby clamping the first pin component 20 in the second pin component 30.

[0046] In some embodiments, the pressing member 35 may include two pressing parts, and the two pressing parts are respectively connected to their corresponding linkage parts 351. Each pressing part can drive a linkage part 351 to slide. In addition, a reset spring can be arranged between the pressing part and its corresponding linkage part 351. When the pressing part is released, the linkage part 351 can be reset under the action of the reset spring.

[0047] Or, if Figure 7-Figure 8As shown, the pressing member 35 may also include only one pressing part, and the two linkage parts 351 are respectively arranged at both ends of the pressing part. By applying a force along the third direction L3 to the pressing part, the pressing part drives the two linkage parts 351 to slide synchronously. The specific sliding method here is described in detail below.

[0048] See also Figure 7-Figure 9 In some embodiments of the present application, a guide groove 343 is provided on the side of the first part 341 away from the second part 342, and a guide groove 343 is also provided on the side of the second part 342 away from the first part 341. When the second pin assembly 30 is in use, the linkage portion 351 is inserted into the corresponding guide groove 343; when force is applied to the pressing piece 35, the pressing piece 35 slides relative to the shell 32, and the linkage portion 351 disengages from the corresponding guide groove 343 and abuts against the side wall of the corresponding first part 341 or the second part 342.

[0049] Among them, Figure 8-Figure 9 As shown, the first part 341 and the second part 342 are spaced apart along the second direction L2, and the first part 341 and the second part 342 can slide along the second direction L2, and the linkage part 351 slides along the side walls of the first part 341 and the second part 342, that is, the linkage part 351 can slide along the third direction L3, and the third direction L3 is perpendicular to the second direction L2. When the first pin assembly 20 is plugged into the second pin assembly 30 and the second pin assembly 30 is in use, the two linkage parts 351 are inserted into the corresponding guide grooves 343, one linkage part 351 is engaged with the groove of the first part 341, and the other linkage part 351 is engaged with the groove of the second part 342. At this time, the distance between the first part 341 and the second part 342 is a, and the groove can be recessed from the side wall of the first part 341 or from the side wall of the second part 342, and the groove can have an inclined groove wall; the first pin assembly 20 needs to be inserted into the second pin assembly 30. When the foot assembly 30 or the second pin assembly 30 is withdrawn, an external force is applied to the pressing member 35 along the third direction L3, and the linkage portion 351 slides from the bottom wall of the corresponding guide groove 343 to the outside of the guide groove 343, until the linkage portion 351 slides out of the corresponding groove of the first part 341 or the groove of the second part 342, until the corresponding side wall of the first part 341 or the side wall of the second part 342 abuts, that is, the linkage portion 351 drives the first part 341 and the second part 342 to slide toward each other, and at this time, the distance between the first part 341 and the second part 342 is b, a>b. It can be understood that, taking the depth of the guide groove 343 as c, the linkage portion 351 slides out of the guide groove 343, that is, the first part 341 and the second part 342 both slide a distance c along the second direction L2, so the distance relationship between the first part 341 and the second part 342 satisfies b=a-2c.

[0050] Exemplarily, the groove side wall of the guide groove 343 has a first inclined surface, and during the sliding process of the linkage part 351, the linkage part 351 can enter and exit the guide groove 343 along the first inclined surface, and the first inclined surface provides a guide for the linkage part 351 to enter and exit.

[0051] For further information, please see Figure 7-Figure 9 In some embodiments of the present application, the second pin assembly 30 further includes an elastic member 36 , which is disposed between the first portion 341 and the second portion 342 , and is used to reset the first portion 341 and the second portion 342 .

[0052] Specifically, when the first part 341 and the second part 342 slide toward each other, the distance between the first part 341 and the second part 342 decreases, and the first part 341 and the second part 342 compress the elastic member 36, and at this time, the clamping structure 345 is in contact with the clamping slot 22; when the clamping structure 345 completely enters the clamping slot 22 or completely leaves the clamping slot 22, the external force on the pressing member 35 disappears, and the elastic force of the elastic member 36 causes the first part 341 and the second part 342 to slide back to each other, and the distance between the first part 341 and the second part 342 increases, and the linkage part 351 slides into the guide groove 343 along the first inclined surface, and at this time, the first part 341 and the second part 342 are reset under the action of the elastic member 36. The elastic member 36 can be a spring.

[0053] In the second aspect, the embodiment of the present application further provides a charger, including an electrical interface, a conductive wire, and a plug 1 as described in any of the above embodiments, wherein the electrical interface and the plug 1 are connected to opposite ends of the conductive wire.
