[0032] In related technologies, three-pronged adapters are equipped with ground, live, and neutral pins, while charging heads have live and neutral pins. By using a three-pronged adapter to connect a two-pronged charger, the charger can successfully charge devices requiring grounding protection. However, because the charging head and adapter are detachably connected in these technologies, the connection between the charger and adapter is unstable, and there is a risk of grounding failure, leading to insufficient electrical safety.

[0033] In view of this, refer to Figures 1 to 7 This application provides a power converter 100, which includes an adapter 10 and a power conversion body 20. The power conversion body 20 can be a mobile phone charger or a computer charger, etc.

[0034] The adapter 10 includes a first mounting base 16, a first ground wire conductor 15, and a live wire adapter pin 13, a neutral wire adapter pin 14, and a ground wire adapter pin 12 disposed on the first mounting base 16.

[0035] The first mounting base 16 is provided with a first plug-in protrusion 11, and a first ground wire conductor 15 is disposed on the first plug-in protrusion 11 and electrically coupled to the ground wire adapter pin 12. The first ground wire conductor 15 can be connected to the ground wire adapter pin 12 through the first connecting piece 152, thereby realizing the electrical coupling between the first ground wire conductor 15 and the ground wire adapter pin 12.

[0036] The power conversion body 20 is detachably connected to the adapter 10. The power conversion body 20 includes a second mounting base 26 and a live wire pin 23, a neutral wire pin 24, and a second ground wire conductor 25 disposed on the second mounting base 26. The first plug-in protrusion 11 is inserted into the first assembly groove 22.

[0037] The second mounting base 26 is provided with a first mounting slot 22, where the live wire pin 23 is electrically coupled to the live wire adapter pin 13 to conduct the live wire, and the neutral wire pin 24 is electrically coupled to the neutral wire adapter pin 14 to conduct the neutral wire.

[0038] The first ground wire conductor 15 is plugged into the second ground wire conductor 25.

[0039] In the above embodiments, by providing a first insertion protrusion 11 on the first mounting base 16 and an assembly groove on the second mounting base 26, the first insertion protrusion 11 and the assembly groove cooperate with each other, making it difficult for the first mounting base 16 and the second mounting base 26 to separate. Furthermore, by inserting the first ground wire conductor 15 on the adapter 10 into the second ground wire conductor 25 on the power conversion body 20, the first ground wire conductor 15 and the second ground wire conductor 25 mutually restrain each other, maintain close contact, and are not easily separated. Thus, the power conversion body 20 and the adapter 10 are not easily separated, which helps to improve the connection stability between the power conversion body and the adapter and improve electrical safety.

[0040] Reference Figure 7 In some embodiments, the first grounding conductor 15 may include a first connecting piece 152 and a pin 151 connected to each other. The second grounding conductor 25 may include a second connecting piece 252 and a spring piece 251 connected to each other. The second connecting piece 252 is used for other electrical connections (not shown) on the power conversion body 20 to achieve power grounding. After the first grounding conductor 15 and the second grounding conductor 25 are inserted, the spring piece 251 abuts against the periphery of the pin 151.

[0041] The spring 251 is a metal part, which can be made of highly conductive materials such as copper, copper alloys, and stainless steel. These materials not only have good electrical conductivity, but also good mechanical strength and corrosion resistance.

[0042] For example, such as Figure 7 As shown, the pin 151 can be constructed as a cylinder, with a spring piece 251 abutting against the circumferential surface of the pin 151. Three spring pieces 251 can be provided, spaced apart circumferentially around the pin 151. A flared portion 2511 can be provided at the end of the spring piece 251 facing the pin 151, and a constricted neck 2512 can be provided near the flared portion 2511. The flared portion 2511 has an expanding tendency; when the first ground wire conductor 15 and the second ground wire conductor 25 are inserted, the flared portion 2511 expands, helping the pin 151 to align and insert into the first ground wire conductor 15. The constricted neck 2512 has a tightening tendency; after the first ground wire conductor 15 and the second ground wire conductor 25 are inserted, the constricted neck 2512 firmly abuts against the circumferential surface of the pin 151, making it difficult for the pin 151 to dislodge.

[0043] In the above embodiments, the spring piece 251 abuts against the circumferential surface of the pin 151, which reduces the difficulty of connecting the first ground wire conductor 15 and the second ground wire conductor 25 and has high connection stability.

[0044] It should be understood that in other embodiments, the second ground conductor 25 may also be configured as a structure such as a metal ring fitted around the outer periphery of the pin 151.

[0045] In some embodiments, the neutral wire pin 24 is foldably disposed on the second mounting base 26, with the neutral wire pin 24 folded toward the first mounting groove 22. After folding, a portion of the neutral wire pin 24 is located in the first mounting groove 22. The live wire pin 23 is foldably disposed on the second mounting base 26, with the live wire pin 23 folded toward the first mounting groove 22. After folding, a portion of the live wire pin 23 is located in the first mounting groove.

[0046] With this configuration, the power converter unit 20 can be used independently after the neutral wire pin 24 and the live wire pin 23 are unfolded, which helps improve the compatibility of the power converter 100. When the neutral wire pin 24 and the live wire pin 23 are folded, they are easy to carry, which helps improve the portability of the power converter 100.

[0047] In some embodiments, with the neutral pin 24 and the live pin 23 folded, the adapter 10 is connected to the power charging body, which reduces the overall size of the power converter 100 and helps to meet the miniaturization requirements of the power converter 100.

[0048] In some embodiments, the second mounting base 26 is further provided with a second insertion protrusion 21, and the first insertion protrusion 11 is further provided with a second mounting groove 114 that mates with the second insertion protrusion 21. The first ground wire conductor 15 is disposed in the second mounting groove 114. For example, as shown... Figure 5 As shown, the first electrical connector is located inside the first mounting base 16, and the pin 151 extends into the second mounting groove 114.

[0049] By partially placing the first ground wire conductor 15 in the second mounting groove 114, the first plug-in protrusion 11 can provide a certain degree of shielding for the first ground wire conductor 15. This arrangement reduces the risk of electric shock for the user during the connection between the adapter 10 and the power conversion body 20. Simultaneously, it also provides a larger connection area between the first ground wire conductor 15 and the second ground wire conductor 25, thereby improving the connection stability between them. Furthermore, the cooperation between the second plug-in protrusion 21 and the second mounting groove 114 increases the connection area between the first mounting base 16 and the second mounting base 26, making them less prone to separation, which also contributes to improving the connection stability between the first ground wire conductor 15 and the second ground wire conductor 25.

[0050] In some embodiments, the first insertion protrusion 11 includes a first guide rail 111, a second guide rail 112, and a connecting portion 113. The first guide rail 111 and the second guide rail 112 are disposed opposite to each other, and the connecting portion 113 connects the first guide rail 111 and the second guide rail 112. The first guide rail 111, the second guide rail 112, and the connecting portion 113 define a second mounting groove 114. The first mounting groove 22 includes a first guide groove 221 that mates with the first guide rail 111 and a second guide groove 222 that mates with the second guide rail 112.

[0051] When the adapter 10 is connected to the power conversion body 20, the first guide rail 111 is inserted into the first guide groove 221 and the second guide rail 112 is inserted into the second guide groove 222, thereby guiding the first plug-in protrusion 11 to be assembled into the first assembly groove (22). The adapter 10 and the power conversion body 20 are quickly assembled, which helps to improve the assembly efficiency of the adapter 10 and the power conversion body 20.

[0052] In some embodiments, the first guide rail 111 is provided with a neutral wire pin slot 11111 for inserting a folded neutral wire pin 24. The neutral wire pin 24 is configured to be electrically coupled to the neutral wire adapter pin 14 after the first plug-in protrusion 11 is fitted into the first mounting groove 22. The second guide rail 112 is provided with a live wire pin slot 11211 for inserting a folded live wire pin 23. The live wire pin 23 is configured to be electrically coupled to the live wire adapter pin 13 after the first plug-in protrusion 11 is fitted into the first mounting groove 22.

[0053] In some embodiments, the extension directions of the first guide rail 111, the second guide rail 112, and the first ground wire conductor 15 can be the same, so that the assembly directions of the first mounting base 16 and the second mounting base 26 are the same as the assembly directions of the first ground wire conductor 15 and the second ground wire conductor 25, which helps to reduce the assembly difficulty of the adapter 10 and the power conversion body 20.

[0054] In some embodiments, such as Figure 5 As shown, a first slide rail 1112 can also be provided on the first guide rail 111. The first slide rail 1112 is used to guide the first guide rail 111 into the first guide groove 221. A second slide rail 1122 can also be provided on the second guide rail 112. The second slide rail 1122 is used to guide the second guide rail 112 into the second guide groove 222.

[0055] In some embodiments, the first guide rail 111 is provided with a first limiting part 1111, which is configured to restrict the first guide rail 111 from disengaging from the first guide groove 221 after the first guide rail 111 is assembled into the first guide groove 221, so as to further improve the connection stability between the first mounting base 16 and the second mounting base 26.

[0056] In some embodiments, the second guide rail 112 is further provided with a second limiting part 1121, which is configured to restrict the second guide rail 112 from disengaging from the first guide groove 221 after the second guide rail 112 is assembled into the second guide groove 222, so as to further improve the connection stability between the first mounting base 16 and the second mounting base 26.

[0057] In some embodiments, the first limiting part 1111 is a buckle disposed at the end of the first guide rail 111.

[0058] In some embodiments, the second limiting part 1121 is a buckle disposed at the end of the second guide rail 112.

[0059] In other embodiments, the first limiting part 1111 may also be a protrusion structure disposed on the outer peripheral surface of the first ground wire conductor 15, and correspondingly, the second limiting part 1121 may also be a protrusion structure disposed on the outer peripheral surface of the second ground wire conductor 25.

[0060] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
