[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The current converter and socket-plug combination device provided by the present invention are described in detail below with reference to the embodiments.

[0035] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram from a first angle of an embodiment of the current converter of the present application; Figure 2 It is a second angle schematic diagram of an embodiment of the current converter of the present application. The present application provides a current converter. The current converter 10 includes a conversion shell 11, a conversion socket 12 and a conversion plug 13. The conversion shell 11 is formed with a mounting cavity 113. The mounting cavity 113 provides mounting space for the conversion socket 12 and the conversion plug 13. The conversion socket 12 is arranged in the mounting cavity 113. For example, the conversion socket 12 can be detachably connected to the mounting cavity 113. The conversion socket 12 includes a ground wire spring 1211. One end of the conversion socket 12 is used to connect to the power plug 20. For example, one end of the conversion socket 12 is connected to the power plug 20; or the conversion socket 12 is disconnected from the power plug 20. The power plug 20 can be, but is not limited to, a car charger (not shown in the figure), etc.

[0036] The conversion plug 13 is arranged in the installation cavity 113. The conversion plug 13 is electrically connected to the conversion socket 12. The conversion plug 13 includes a first ground terminal 1311. The first ground terminal 1311 is connected to the ground spring 1211. For example, the first ground terminal 1311 and the ground spring 1211 are detachably connected. The first ground terminal 1311 at least partially extends out of an end surface of the installation cavity 113. For example, the conversion plug 13 is connected to a power socket (not shown in the figure); or the conversion plug 13 is disconnected from the power socket. The conversion plug 13 is used to connect to the power socket. The power socket can be a conventional socket and is not limited here.

[0037] See also Figure 3 、 Figure 4 and Figure 5 , Figure 3 is a cross-sectional schematic diagram of an embodiment of the current converter of the present application; Figure 4 This is a first partial schematic diagram of an embodiment of the current converter of the present application; Figure 5 This is an exploded diagram of an embodiment of the current converter of the present application. Figure 1 and Figure 2 The current converter 10 also includes a first temperature measuring component 14 and a signal component 15. The first temperature measuring component 14 is arranged in the installation cavity 113. One end of the first temperature measuring component 14 is connected to the ground wire spring 1211. The first temperature measuring component 14 can detect the first temperature inside the current converter 10 in real time. When the first temperature exceeds the first preset temperature threshold, the power plug 20 and the current converter 10 are automatically disconnected to achieve the first layer of temperature protection. The signal component 15 is arranged in the installation cavity 113. One end of the signal component 15 is connected to the other end of the first temperature measuring component 14. The other end of the signal component 15 is used to connect to the power plug 20. The signal component 15 can transmit signals. The above-mentioned first temperature measuring component 14 and signal component 15 can be directly placed or confined in the installation cavity 113, etc.

[0038] When the power plug 20 is plugged into the conversion socket 12, the signal element 15 contacts and conducts with the corresponding connection terminal (such as the signal terminal 244) on the power plug 20. The power plug 20 can obtain the current signal on the signal element 15 and adjust the output current to match the current specification of the power socket according to the current signal, thereby ensuring the safety of electricity use. Furthermore, the first temperature measuring element 14 measures the first temperature inside the current converter 10 in real time. The signal element 15 feeds back the first temperature signal to the power plug 20 until the first temperature exceeds the first preset temperature threshold. The power plug 20 disconnects from the current converter 10, further improving the safety of use. Therefore, by adding the signal element 15 and the first temperature measuring element 14 to the current converter 10 at the same time, not only is the signal recognition and feedback function added, so that the power plug 20 can identify the current converter 10 and limit the current when it is used to ensure the safety of electricity use, but also the temperature measurement protection function is added, thereby improving the safety of use.

[0039] For example, let's take the charging of electric vehicles as an example. Electric vehicles are charged using a charger, and the charger (not shown in the figure) includes a power plug 20, a control module (not shown in the figure) and a charging gun head (not shown in the figure). The control module, the charging gun head and the power plug 20 are electrically connected. The control module is used to control the output current of the charging gun head, and the charging gun head is used to charge the electric vehicle. A signal terminal 244 is provided on the power plug 20, and the signal terminal 244 is connected to the signal member 15. When the power plug 20 is connected to the conversion socket 12 of the current converter 10, the signal terminal 244 abuts against the signal member 15 and is turned on. The control module can obtain the current of the current converter 10. The control module intelligently recognizes that the power plug 20 is inserted into the current converter 10 based on the current adjustment signal, and then controls the charging gun head to output a current of 16A, so that the charger can charge the electric vehicle normally and ensure the safety of use between the charger and the power socket.

[0040] Furthermore, when the first temperature detected by the first temperature measuring element 14 exceeds a first preset temperature threshold, the control module disconnects the power plug 20 from the current converter 10, thereby implementing a first level of temperature protection. The first temperature measuring element 14 may be, but is not limited to, a first temperature sensor (not shown).

[0041] See also Figure 6 and Figure 7 , Figure 6 This is a schematic structural diagram of the first protective cover in the current converter of the present application; Figure 7 This is a first structural diagram of the second protective cover and protective assembly in the current converter of the present application. Figures 1 to 4 In some embodiments, the conversion socket 12 includes a protective component 122. The protective component 122 includes a protective shell (not shown in the figure). The signal part 15 includes a first signal part 151 and a second signal part 152. The first signal part 151 and the second signal part 152 are bent between each other. The first signal part 151 and the second signal part 152 are fixedly connected. The first signal part 151 is located on a side of the protective shell away from the conversion plug 13. That is, the first signal part 151 is used to connect to the power plug 20. The second signal part 152 passes through the protective shell so that the signal part 15 is connected to the protective shell. The second signal part 152 is connected to the other end of the first temperature measuring part 14. By connecting the signal part 15 to the protective shell, the signal part 15 can be limited, thereby improving the stability of the installation of the signal part 15.

[0042] The conversion housing 11 defines a conversion hole 114. The orthographic projection of the conversion hole 114 onto the first signal portion 151 is located within the first signal portion 151. When the power plug 20 is connected to the conversion socket 12, the conversion hole 114 allows for contact and communication with the first signal portion 151 of the signal member 15. The orthographic projection of the conversion hole 114 onto the first signal portion 151 can be smaller than or equal to the area of ​​the first signal portion 151. This ensures that the power plug 20 contacts and connects with the signal member 15 through the conversion hole 114, while also minimizing safety concerns associated with an overly large conversion hole 114.

[0043] In some embodiments, the protective housing includes a first protective cover 1221 and a second protective cover 1222. The first protective cover 1221 is provided with a first signal hole 12211. The first signal hole 12211 provides an installation location for the second signal portion 152. A signal groove 12212 is provided on a side of the first protective cover 1221 facing away from the second protective cover 1222. The first signal hole 12211 and the signal groove 12212 are connected. The second signal portion 152 is plugged into the first signal hole 12211. The first signal portion 151 is embedded in the signal groove 12212. By means of the above-mentioned plugging and embedding of the signal member 15, the stability of the signal member 15 installed in the protective assembly 122 is improved.

[0044] The shape of the signal groove 12212 can match the shape of the first signal portion 151 to ensure that the signal member 15 can be stably connected to the protective housing. Of course, in other embodiments, the shape of the signal groove 12212 can also be different from the shape of the first signal portion 151, as long as the size of the signal groove 12212 is larger than the size of the first signal portion 151.

[0045] The signal member 15 may be, but is not limited to, a signal sheet (not shown). The first signal portion 151 of the signal sheet may be, but is not limited to, a flat circular, oval, or square shape. The shape of the first signal portion 151 can increase the contact area. The second signal portion 152 of the signal sheet may be, but is not limited to, a flat, elongated strip.

[0046] In some embodiments, the second protective cover 1222 is provided with a second signal hole (not shown). The second signal hole provides a mounting location for the second signal unit 152. The second signal unit 152 is plugged into both the first signal hole 12211 and the second signal hole. At the same time, the end of the second signal unit 152, which is away from the first signal unit 151, extends from the side of the second protective cover 1222 that faces away from the first protective cover 1221, and then connects to the other end of the first temperature measuring element 14. This further improves the stability of the signal unit 15 installed in the protective housing.

[0047] In some embodiments, the conversion socket 12 also includes a live wire spring 1212. The conversion plug 13 also includes a first live wire terminal 1312. The current converter 10 also includes a temperature overload protector 16. One end of the temperature overload protector 16 is connected to the live wire spring 1212. The other end of the temperature overload protector 16 is connected to the first live wire terminal 1312. The temperature overload protector 16 can detect the second temperature of the live wire terminal of the current converter 10 and its surroundings in real time. When the second temperature exceeds the second preset temperature threshold, the temperature overload protector 16 automatically disconnects, and the current converter 10 cannot be powered on. When the second temperature is lower than the second preset temperature threshold, the temperature overload protector 16 operates normally. By providing the temperature overload protector 16 in the current converter 10, the current converter 10 can add a power-off protection function, realize a second layer of temperature protection, thereby protecting the current converter 10 and preventing the internal temperature of the current converter 10 from being too high and causing a fire, thereby improving safety performance.

[0048] The thermal overload protector 16 and the first temperature measuring element 14 of the current converter 10 work together to provide dual temperature protection for the current converter 10, further enhancing safety. The specific value of the second preset temperature threshold in the thermal overload protector 16 can be set based on the type of current converter 10 and is not limited here. The operating principle of the thermal overload protector 16 is conventional for those skilled in the art and will not be further described here.

[0049] In some embodiments, the conversion socket 12 is a three-stage socket (not shown in the figure). The conversion plug 13 is a three-stage plug (not shown in the figure). Specifically, the conversion socket 12 also includes a neutral wire spring 1213. The conversion plug 13 also includes a first neutral wire terminal 1313. The neutral wire spring 1213 is connected to the first neutral wire terminal 1313. The first ground wire terminal 1311, the first live wire terminal 1312, and the first neutral wire terminal 1313 all at least partially extend out of one end face of the mounting cavity 113. The first ground wire terminal 1311, the first live wire terminal 1312, and the first neutral wire terminal 1313 are all mounted on a side face of the second protective cover 1222 facing away from the first protective cover 1221 through corresponding brackets. For example, the first ground terminal 1311 is mounted on the second protective cover 1222 via a ground bracket (not shown in the figure), the first live terminal 1312 is mounted on the second protective cover 1222 via a live bracket (not shown in the figure), and the first neutral terminal 1313 is mounted on the second protective cover 1222 via a neutral bracket (not shown in the figure). The neutral spring clip 1213 is detachably connected to the first neutral terminal 1313, such as by riveting. The ground spring clip 1211 is detachably connected to the first ground terminal 1311, such as by riveting. The first live terminal 1312 is detachably connected to the live bracket, etc. Through the above-described method, the stability of the internal electrical connection of the current converter 10 is achieved.

[0050] See also Figures 8 to 10 , Figure 8 This is a second structural schematic diagram of the second protective cover and protective assembly in the current converter of the present application; Figure 9 It is a schematic diagram of the structure of the protection gate in the current converter of the present application; Figure 10 This is a schematic diagram of the structure of the second protective cover in the current converter of the present application. Figures 4 to 7 In some embodiments, the conversion socket 12 includes a protective assembly 122. The protective assembly 122 includes a second protective cover 1222 and a protective door 1223. The second protective cover 1222 is provided with three second terminal jacks 1224. The second terminal jacks 1224 are used to be plugged into the power plug 20. The protective door 1223 rotates horizontally relative to the second protective cover 1222. During the horizontal rotation of the protective door 1223 relative to the second protective cover 1222, the protective door 1223 has at least a first state and a second state. When the protective door 1223 is in the first state, the protective door 1223 can cover the three second terminal jacks 1224 at the same time. When the protective door 1223 is in the second state, the protective door 1223 can open one second terminal jack 1224 at the same time.

[0051] By horizontally rotating the protective door 1223 relative to the second protective cover 1222, the three second terminal jacks 1224 can be covered or opened, achieving automatic opening and closing of the protective door 1223, thereby improving ease of use and safety. When the protective door 1223 covers the three second terminal jacks 1224, the protective door 1223 can provide a shielding effect, thereby improving safety in use.

[0052] In some embodiments, the protective door 1223 includes a driving portion 12231 and a rotating portion 12232. The driving portion 12231 is connected to the rotating portion 12232. For example, the driving portion 12231 may be detachably or fixedly connected to the rotating portion 12232. As in this embodiment, the driving portion 12231 and the rotating portion 12232 are integrally formed and connected. The driving portion 12231 is provided with an openable and closable cover over one second terminal receptacle 1224. When the protective door 1223 is in the first state, the driving portion 12231 covers one second terminal receptacle 1224. When the protective door 1223 is in the second state, the driving portion 12231 opens one second terminal receptacle 1224. The rotating portion 12232 is provided with an openable and closable cover over two second terminal receptacles 1224. When the protective door 1223 is in the first state, the rotating portion 12232 covers the two second terminal receptacles 1224. When the protection door 1223 is in the second state, the rotating portion 12232 opens the two second terminal insertion holes 1224 .

[0053] In one embodiment, the drive unit 12231 is provided with a driving bevel 12233. The driving bevel 12233 is positioned toward the rotating shaft 1225 and the elastic member 1226. When the power plug 20 is plugged into the conversion socket 12, the power plug 20 acts on the driving bevel 12233 on the drive unit 12231, causing one side of the protective door 1223 to rotate a certain angle toward the elastic member 1226 and the rotating shaft 1225, thereby opening the three second terminal receptacles 1224. The provision of the driving bevel 12233 on the drive unit 12231 makes rotating the protective door 1223 more labor-efficient and time-saving, thereby improving the user experience.

[0054] In another embodiment, the rotating portion 12232 is provided with an escape groove 12234. The escape groove 12234 can provide a certain degree of escape, making it easier for the power plug 20 to be plugged into the conversion socket 12. The driving portion 12231 is located above the rotating portion 12232. One side of the rotating portion 12232 is sleeved on the rotating shaft 1225.

[0055] Specifically, the three second terminal jacks 1224 on the second protective cover 1222 are a ground jack 12241, a neutral jack 12242, and a live jack 12243. The driving unit 12231 is provided with a retractable cover on the ground jack 12241. The rotating unit 12232 is provided with a retractable cover on the neutral jack 12242 and the live jack 12243.

[0056] In some embodiments, the protective assembly 122 further includes a rotation shaft 1225. The rotation shaft 1225 is disposed on the second protective cover 1222. The rotation shaft 1225 can be detachably or fixedly connected to the second protective cover 1222. In this embodiment, the rotation shaft 1225 is integrally formed with the second protective cover 1222. Furthermore, the rotation shaft 1225 is located on one side of the protective door 1223. One side of the protective door 1223 is sleeved on the rotation shaft 1225. The protective door 1223 rotates horizontally via the rotation shaft 1225, so that the protective door 1223 has a first state and a second state, thereby enabling the protective door 1223 to open and close.

[0057] In addition, the protective assembly 122 also includes an elastic member 1226. The first elastic leg of the elastic member 1226 abuts (not shown) against the second protective cover 1222. The second elastic leg of the elastic member 1226 abuts against one side of the protective door 1223. The elastic member 1226 can provide a restoring force to restore the protective door 1223 to its original state. The elastic member 1226 can be, but is not limited to, a torsion spring. The elastic member 1226 can achieve automatic opening and closing of the protective door 1223, thereby improving user convenience and safety.

[0058] A first stopper 1227 is provided on the side of the second protective cover 1222 facing the first protective cover 1221. The first stopper 1227 can limit the first elastic leg of the elastic member 1226. A second stopper 1228 is also provided on the side of the second protective cover 1222 facing the first protective cover 1221. When the protective door 1223 returns to its original position under the action of the elastic member 1226, the second stopper 1228 can limit further rotation of the protective door 1223, thereby preventing excessive rotation of the protective door 1223.

[0059] In some embodiments, the protective assembly 122 further includes a first protective cover 1221. A protective cavity (not shown) is formed between the first protective cover 1221 and the second protective cover 1222. The protective door 1223, the rotating shaft 1225, the elastic member 1226, the first limiting portion 1227, and the second limiting portion 1228 are all located within the protective cavity. The first protective cover 1221 and the second protective cover 1222 are detachably connected. The first protective cover 1221 and the second protective cover 1222 are each detachably connected to the conversion housing 11.

[0060] Furthermore, the conversion housing 11 includes a conversion cover 111 and a conversion outer shell 112. The conversion cover 111 and the conversion outer shell 112 define the aforementioned mounting cavity 113. The conversion cover 111 defines three conversion terminal jacks 1111. The first protective cover 1221 defines three first terminal jacks 12213. The three conversion terminal jacks 1111, the three first terminal jacks 12213, and the three second terminal jacks 1224 are positioned relative to each other.

[0061] See also Figures 11 to 13 , Figure 11 This is a partial exploded schematic diagram of an embodiment of the socket-plug combination device of the present application; Figure 12 It is a partial schematic diagram of the electrical plug used in the socket-plug combination device of the present application; Figure 13 This is a partial cross-sectional diagram of the electrical plug used in the socket and plug combination device of the present application. Figures 1 to 10 The present application provides a socket-plug combination. The socket-plug combination (not shown) includes a current converter 10 and a power plug 20. The power plug 20 includes a signal terminal 244. The signal terminal 244 is capable of signal recognition. The signal terminal 244 is releasably engaged with the signal element 15 in the current converter 10. Alternatively, the signal terminal 244 and the signal element 15 are released from engagement.

[0062] The current converter 10 and the power plug 20 described above cooperate with each other. By providing a signal terminal 244 on the power plug 20, when the power plug 20 is plugged into the current converter 10, the power plug 20 can perform signal recognition and control the current within the rated range, thereby preventing safety accidents and improving safety performance. It should be noted that the current converter 10 in this embodiment is the current converter 10 described in the above embodiment and will not be described in detail here. The signal terminal 244 is conventional technology used by those skilled in the art and is not limited here.

[0063] Specifically, the power plug 20 includes a first signal input line 251. The signal terminal 244 is connected to the first signal input line 251, enabling signal transmission feedback, signal recognition, and improved safety. When the power plug 20 is plugged into the current converter 10, the first ground terminal 1311, the ground spring 1211, the first temperature measuring element 14, the signal element 15, the signal terminal 244, and the first signal input line 251 form a signal loop.

[0064] In some embodiments, the power plug 20 further includes a second temperature measuring element 245, a second ground terminal 241, and a second signal input line 252. One end of the second temperature measuring element 245 is connected to the second ground terminal 241. The other end of the second temperature measuring element 245 is connected to the second signal input line 252. The second temperature measuring element 245 may be, but is not limited to, a second temperature sensor, etc. The second temperature measuring element 245 can detect the third temperature inside the power plug 20 in real time. When the third temperature exceeds the third preset temperature threshold, the power plug 20 is automatically disconnected from the current converter 10 to achieve a third level of temperature protection. In the above manner, temperature monitoring is achieved, thereby improving safety performance. Among them, the ground wire, the second ground terminal 241, the second temperature measuring element 245, and the second signal input line 252 are connected in sequence.

[0065] In some embodiments, the power plug 20 includes a power housing 21 and a power bracket 22. A signal terminal 244 is connected to the power bracket 22 so that the signal terminal 244 is fixed to the power bracket 22. Furthermore, the signal terminal 244 protrudes from the surface of the power bracket 22. When the power plug 20 is plugged into the current converter 10, the signal terminal 244 can abut against the first signal portion 151 through the conversion hole 114 of the conversion housing 11. This arrangement of the signal terminal 244 not only secures the signal terminal 244 but also ensures accurate connection between the signal terminal 244 and the signal member 15.

[0066] See also Figure 14 , Figure 14 This is a partial exploded schematic diagram of the electrical plug in the socket and plug combination device of this application. Figures 1 to 13In some embodiments, the power support 22 is provided with three power terminal jacks (not shown in the figure). The three power terminal jacks are used to respectively install the second ground terminal 241, the second live terminal 242 and the second neutral terminal 243, etc. The power support 22 is penetrated by a first limiting groove 221, and the signal terminal 244 is inserted into the first limiting groove 221, wherein the signal terminal 244 at least partially protrudes from the surface of the first limiting groove 221. Among them, the signal terminal 244 is arranged perpendicular to the surface of the power support 22. The first limiting groove 221 can be set in the three power terminal jacks or in the three power terminal jacks. As in this embodiment, the first limiting groove 221 is located on the outer peripheral surface of the three power terminal jacks. In addition, a second limiting groove (not shown in the figure) is provided on one end face of the power support 22 facing the power shell 21. The second limiting groove can be used to install the second temperature measuring component 245, etc. The second limiting groove can be located in the three power terminal jacks.

[0067] In some embodiments, the power plug 20 further includes a cable 25. The cable 25 includes the first signal input line 251 and the second signal input line 252 described above. The power housing 21 is injection molded and entirely surrounds the power bracket 22 and one end of the cable 25, such that the signal terminal 244, the second ground terminal 241, the second live terminal 242, the second neutral terminal 243, and the second temperature measuring element 245 are all located within the power housing 21.
