[0054] An embodiment of this application provides a foldable plug structure, as Figures 1 to 5 shown, the foldable plug structure includes a live pin 10, a neutral pin 20, and a housing 30;

[0055] The live pin 10 has a first fixed end 11 and a first extension end 12;

[0056] The neutral pin 20 is arranged at an interval from the live pin 10, and the neutral pin 20 has a second fixed end 21 and a second extension end 22;

[0057] An accommodation space is formed in the housing 30, and a bracket 31 is rotatably arranged in the housing 30. The bracket 31 is fixedly connected to the first fixed end 11 and the second fixed end 21 respectively, and the first fixed end 11 and the second fixed end 21 are located in the accommodation space. The first extension end 12 and the second extension end 22 pass through the housing 30 and are located outside the housing 30. A storage groove 300 is provided on the outer surface of the housing 30, and the storage groove 300 is used to accommodate the live pin 10 and the neutral pin 20.

[0058] For the foldable plug structure provided by the embodiment of this application, the live pin 10 and the neutral pin 20 are fixed to the bracket 31, and then the bracket 31 is rotatably arranged in the housing 30, so as to realize the rotation of the live pin 10 and the neutral pin 20. When it is necessary to store the foldable plug structure, the first extension end 12 and / or the second extension end 22 can be rotated and rotated into the storage groove 300 for storage, and the live pin 10 and the neutral pin 20 are stored and folded, so as to be hidden, avoiding the end of the plug from scratching other valuable items stored together with it, especially laptops, mobile phones or other jewelry, etc.

[0059] In application, the live pin 10 and the neutral pin 20 are insert - molded, and by integrally injection - molding the two pins, namely the live pin 10 and the neutral pin 20, with the bracket 31, the integration of the two pins is achieved, enabling the neutral pin 20 and the live pin 10 to be directly rotatably connected to the housing 30 through the bracket 31. That is, by rotating either pin, the two pins can be folded or opened simultaneously.

[0060] In some embodiments, as Figure 5 and Figure 6 shown, the foldable plug structure further includes a ground pin 40 and a connecting member 50;

[0061] The ground pin 40 has a third fixed end 41 and a third extension end 42;

[0062] One end of the connecting member 50 is rotatably connected to the bracket 31, and the other end of the connecting member 50 is fixedly connected to the third end;

[0063] Among them, by rotating at least one of the live pin 10, the neutral pin 20, and the ground pin 40, the folding of the three pins is realized. Through the connection of the connecting member 50, the three pins are in series, so that rotating any one pin can realize the rotation of the other two, which greatly facilitates daily use.

[0064] In application, the ground pin 40 (also known as the earthing pin) in the power plug mainly serves for safety considerations. It is to prevent the metal shell of the electrical equipment from being electrified and causing electric shock accidents. Specifically, the functions of the ground pin 40 include: providing a low - impedance path: when a fault occurs inside the electrical appliance, such as insulation damage resulting in current leakage to the shell, the ground wire can provide a low - impedance path for this current to directly return to the ground, thus preventing the human body from becoming the path through which the current passes. Reducing the risk of electric shock: If the shell of the electrical appliance is accidentally electrified, the presence of the grounding pin can significantly reduce the risk of electric shock. Because in most cases, the resistance of the ground wire is much smaller than that of the human body, and the current will tend to flow through the ground wire to the earth rather than through the human body. Protecting electrical equipment: In addition to protecting personal safety, grounding can also help protect the electrical appliance itself from abnormal conditions such as over - voltage or lightning strikes, and extend the service life of the electrical appliance.

[0065] In application, the connecting member 50 is a link structure, and its two ends are respectively rotatably connected to the bracket 31 and the third fixed end 41 of the ground pin 40, thereby realizing the synchronous folding and opening of the three pins.

[0066] In some embodiments, the receiving groove 300 is also used to receive the ground pin 40. That is, the receiving groove 300 is a large groove. When the plug is in the folded state, the live pin 10, the neutral pin 20, and the ground pin 40 are simultaneously received and hidden, thereby preventing the pins from scratching other objects. Thus, it is also relatively easy to form the receiving groove 300.

[0067] In some embodiments, as Figures 1 to 4 shown, the receiving groove 300 includes a first receiving groove 301, a second receiving groove 302, and a third receiving groove 303 that are spaced apart from each other. The first receiving groove 301 and the second receiving groove 302 are arranged in parallel, and the third receiving groove 303 is located between the first receiving groove 301 and the second receiving groove 302. The first receiving groove 301 is used to receive the live pin 10, the second receiving groove 302 is used to receive the neutral pin 20, and the third receiving groove 303 is used to receive the ground pin 40.

[0068] In this way, the types of the pins can be effectively and quickly distinguished, and the shapes of different types of pins can be specifically set, so that each pin can be better received. Generally speaking, the live pin 10 and the neutral pin 20 have the same outer shape, while the ground pin 40 is different and has a larger volume. Therefore, the volume of the third receiving groove 303 needs to be set larger, and the position of the ground pin 40 is generally on the midline between the live pin 10 and the neutral pin 20. Therefore, the third receiving groove 303 also needs to be between the first receiving groove 301 and the second receiving groove 302.

[0069] In some embodiments, as Figure 5 and Figure 6 shown, the connecting member 50 includes a first connecting arm 51, a second connecting arm 52, and a fixing arm 53; the second connecting arm 52 is parallel and spaced from the first connecting arm 51. The two ends of the fixing arm 53 are respectively connected to the middle parts of the first connecting arm 51 and the second connecting arm 52. One ends of the first connecting arm 51 and the second connecting arm 52 are respectively rotatably connected to the bracket 31, and the other ends of the first connecting arm 51 and the second connecting arm 52 are rotatably connected to the third fixing end 41.

[0070] In some embodiments, as Figure 5 and Figure 6 shown, the connecting member 50 further includes a first rotating shaft 54, a second rotating shaft 55, and a third rotating shaft 56. Through holes are formed at both ends of the first connecting arm 51 and the second connecting arm 52. The first rotating shaft 54 connects the first connecting arm 51 and the bracket 31, the second rotating shaft 55 connects the second connecting arm 52 and the bracket 31, and the third rotating shaft 56 connects the first connecting arm 51, the second connecting arm 52, and the third fixing end 41. By connecting through rotating shafts, the joints can rotate, thereby realizing the folding and opening of the three pins.

[0071] In some embodiments, such as Figure 5 and Figure 9 shown, the foldable plug structure further includes a first conductive member 60 and a second conductive member 70. One end of the first conductive member 60 is connected to the middle of the live pin 10, and the other end of the first conductive member 60 is fixed to the housing 30. The live pin 10 is electrically connected to the power cord through the first conductive member 60. One end of the second conductive member 70 is connected to the middle of the neutral pin 20, and the other end of the second conductive member 70 is fixed to the housing 30. The neutral pin 20 is electrically connected to the power cord through the second conductive member 70.

[0072] In some embodiments, such as Figure 5 and Figure 9 shown, the foldable plug structure further includes a third conductive member 80. One end of the third conductive member 80 is connected to the middle of the ground pin 40, and the other end of the third conductive member 80 is fixedly connected to the housing 30.

[0073] In some embodiments, such as Figure 5 and Figure 7 shown, the third conductive member 80 includes a support plate, a fixing portion 82 and a conductive portion 83;

[0074] The fixing portions 82 are arranged at both ends of the support portion 81, and the fixing portions 82 are used for connecting with the housing 30;

[0075] The conductive portion 83 is arranged in the middle of the support portion 81, and the conductive portion 83 is used for connecting with the ground pin 40. In this way, the third conductive member 80 can effectively improve the overall stability to ensure the stable grounding of the ground pin 40, thus playing a protective role.

[0076] In some embodiments, the first conductive member 60, the second conductive member 70 and the third conductive member 80 are all conductive copper sheets, and in other embodiments, they can also be other conductive metal sheets.

[0077] In some embodiments, such as Figure 5 and Figure 8 shown, the housing 30 includes a cover body 32 and a bottom shell 33. The cover body 32 and the bottom shell 33 are detachably connected. A first positioning rib 321 is arranged on one side of the cover body 32 close to the bottom shell 33. The first positioning rib 321 is used for cooperating with the bottom shell 33 to fix and position the components inside the housing 30;

[0078] The bottom shell 33 is provided with second positioning ribs 331 for positioning the pins. There are a plurality of second positioning ribs 331, which respectively fix and position the live pin 10, the neutral pin 20 and the ground pin 40. The bottom shell 33 is also provided with fixing columns 332 for fixing the bottom shell 33 and the cover body 32. Blind holes are provided on the fixing columns 332. By passing a screw through the cover body 32 and entering the blind hole, the connection between the bottom shell 33 and the cover body 32 is realized.

[0079] As Figure 9 and Figure 10 shown, when the live pin 10 or the neutral pin 20 rotates, the ground pin 40 is driven to rotate together through the connecting member 50 (rotating with the shaft as the center pivot), so as to achieve the folding purpose as Figure 10 shown.

[0080] The embodiment of the present application further provides a device (not shown) including a foldable plug structure, including a data cable and the foldable plug structure described in the first aspect, and the data cable is connected to the foldable plug structure.

[0081] In applications, the device including the foldable plug structure includes but is not limited to mobile phone chargers, power adapters for computers, plugs for various electrical appliances, etc. Especially chargers for some portable electronic products, such as chargers for small fans, power banks, mobile phones, tablets, laptop computers, etc. Thus, when storing these electronic products and their chargers together, the pins of the plug can be stored and hidden, so as to avoid scratching or damaging valuable items such as mobile phones and computers by the metal pins.

[0082] In the above embodiments, the descriptions of the respective embodiments have their own emphases. For parts not detailed or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
