[0034] 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.

[0035] A plug generally includes a handle and plug electrodes. In some examples, the plug generally has two electrodes. In this case, the plug may include a live (L) pin and a neutral (N) pin. In other examples, the plug may also include a ground (E) pin in addition to the live and neutral pins, increasing the number of plug electrodes to three.

[0036] In some examples, plugs can be further divided into various specifications such as US standard plugs, Japanese standard plugs, or Chinese standard plugs. The plug electrodes (live wire pin and neutral wire pin) of US standard plugs and Japanese standard plugs generally have positioning holes.

[0037] After extensive research, the inventors of this application discovered that, for safety reasons, existing sockets are generally thick, resulting in a generally larger size. Simply reducing the thickness of the socket, while reducing its size, would also result in the plug electrodes not being fully inserted into the socket, leaving them partially exposed to the air. This could increase the risk of electric shock to users and pose a safety hazard. To address this issue, the present application proposes the following embodiments.

[0038] Referring to Figures 1 to 3 , the socket 1 may include a socket body 10, a socket member 20, and a linkage mechanism 30. The socket body 10 may be provided with an electrode member 11. The socket member 20 may have a connector 21 and be arbitrarily mounted on the socket body 10. The linkage mechanism 30 may be disposed on the socket body 10 and in driving connection with the socket member 20. The linkage mechanism 30 is configured to be triggered by the insertion of a plug electrode into the electrode member 11 via the connector 21 in the direction of insertion of the plug electrode, thereby driving the socket member 20 to rise relative to the socket body 10 in the direction of insertion of the plug electrode.

[0039] The direction of elevation of the socket member 20 can be parallel to the direction of insertion of the plug electrode into the socket 21. The socket 21 can be positioned opposite the electrode member 11, for example, above the electrode member 11. The electrode member 11 primarily serves as a conductor. When the plug is inserted into the socket 1, the plug electrode and the electrode member 11 are electrically connected, enabling power transmission. In other examples, the electrode member 11 can also be referred to as a shrapnel or metal shrapnel.

[0040] In this case, the socket member 20 can be raised and lowered relative to the socket body 10, switching between a retracted state and a protruding state. When in the retracted state, the socket member 20 is housed within the socket body 10 (see Figure 2), thereby reducing the size of the socket 1 and making it thinner and lighter. Furthermore, the socket member 20 can rise and switch to a protruding state during the insertion of the plug electrode, which can partially thicken the socket 1 (see Figure 2) and reduce the risk of the plug electrode being exposed.

[0041] Optionally, the linkage mechanism 30 is movably disposed on the socket body 10 and can be pushed by the plug electrode during insertion to drive the socket member 20 upward relative to the socket body 10 in the direction of insertion. In other words, when the plug electrode is inserted, the linkage mechanism 30 can drive the socket member 20 upward under the action of the plug electrode. In this case, the socket member 20 can be responsively switched from the retracted state to the protruding state, reducing the risk of the socket member 20 failing to rise in time, resulting in the plug electrode being exposed.

[0042] Optionally, as shown in Figures 4 and 5 , the linkage mechanism 30 includes a safety gate 31. The safety gate 31 can be movably disposed on the socket body 10 and in driving connection with the receptacle 20. The safety gate 31 is movable relative to the socket body 10 between a first position and a second position. During insertion of the plug electrode, the safety gate 31 is urged by the plug electrode to move from the first position to the second position, thereby driving the receptacle 20 upward relative to the socket body 10 in the direction of insertion. In this case, the linkage mechanism 30 can be improved upon the safety gate 31, thereby reducing the production cost of the socket 1.

[0043] The safety door 31 can at least partially shield the electrode member 11 in the first position, and can expose the electrode member 11 relative to the socket 21 in the second position. In other words, when the safety door 31 is in the first position, it can shield the electrode member 11, reducing the possibility of children or pets accidentally touching the electrode member 11 through the socket 21. When the safety door 31 is in the second position, the plug electrode is inserted into the socket 21 and connected to the electrode member 11. The safety door 31 can be located between the socket body 10 and the socket member 20.

[0044] Optionally, the safety door 31 is provided with a first guide portion 300 (see FIG4 ). The socket member 20 is provided with a second guide portion 200 (see FIG6 ). The first guide portion 300 and the second guide portion 200 are movably connected. The safety door 31 and the socket member 20 are transmission-connected via the first guide portion 300 and the second guide portion 200.

[0045] Optionally, the relative movement path between the first guide portion 300 and the second guide portion 200 is inclined compared to the insertion direction of the plug electrode and the movement direction of the safety door 31 .

[0046] Optionally, as shown in Figures 7 and 8, the first guide portion 300 includes a slide rail mounted on the safety door 31. The second guide portion 200 includes a slider mounted on the socket 20. The slider is slidably mounted on the slide rail. The slide rail extends at an angle relative to both the direction of movement of the safety door 31 and the direction of insertion of the plug electrode. The slide rail guides the slider in relative sliding motion, thereby enabling the socket 20 to be raised or lowered relative to the socket body 10 along the direction of insertion of the plug electrode. The direction of movement of the safety door 31 can be perpendicular to the direction of insertion of the plug electrode.

[0047] In some embodiments, the moving direction of the safety door 31 can be horizontal, and the insertion direction of the plug electrode can be vertical. In addition, when the safety door 31 is in the first position, the slider can be located on the side of the slide rail near the bottom (away from the socket 21). In this case, when the safety door 31 moves horizontally under the action of the plug electrode, the slide rail will also move accordingly. In addition, the extension direction of the slide rail is inclined to the plug-in direction and the movement direction, which means that the slide rail has an upward component in the extension direction. Therefore, when the slider moves relative to the slide rail, it will also generate an upward movement component, thereby enabling the slider and the socket member 20 to move upward as a whole (compared to the socket body 10).

[0048] Optionally, a receiving groove 22 (see FIG6 ) is provided on the side of the socket member 20 facing the safety door 31, which is connected to the receiving groove 21. At least a portion of the safety door 31 is located within the receiving groove 22. A slide rail is provided on the side wall 24 of the safety door 31. A slider is provided on the wall of the receiving groove 22. Specifically, the slide rail can be provided on the side wall 24 extending parallel to the direction of movement of the safety door 31. Correspondingly, the slider can be provided on the wall of the groove extending parallel to the direction of movement of the safety door 31.

[0049] Optionally, the safety door 31 has an abutment surface 310 (see Figure 4). The abutment surface 310 is arranged at an angle relative to the insertion direction of the plug electrode. When the safety door 31 is in the first position, its abutment surface 310 is located between the connector 21 and the electrode member 11 in the insertion direction of the plug electrode. The abutment surface 310 is used to abut the plug electrode, guiding the plug electrode to slide on the abutment surface 310, thereby pushing the safety door 31 from the first position to the second position. In this case, when the plug electrode is inserted into the connector 21, it can slide along the abutment surface 310, driving the safety door 31 from the first position to the second position.

[0050] Optionally, the socket body 10 defines a housing space 100 and a through hole 101 communicating with the housing space 100 (see FIG3 ). The electrode member 11 and the safety door 31 are disposed within the housing space 100. The socket member 20 can be raised and lowered relative to the socket body 10 through the through hole 101 to switch between a retracted state and a protruding state. In the retracted state, the socket member 20 can be submerged within the through hole 101 or flush with the plane of the through hole 101, and in the protruding state, partially protrude from the through hole 101.

[0051] Optionally, the socket body 10 includes an upper shell 13, a lower shell 14, and a fixing frame 15 disposed between the upper shell 13 and the lower shell 14 (see FIG3 ). The upper shell 13 and the lower shell 14 are assembled to enclose a receiving space 100. A through hole 101 is defined in the upper shell 13. The fixing frame 15 is disposed in the receiving space 100. The electrode member 11 is fixedly disposed on the fixing frame 15. The safety door 31 is slidably disposed on the fixing frame 15 and is movable relative to the fixing frame 15 between a first position and a second position.

[0052] Optionally, as shown in FIG6 , the socket member 20 includes a housing 23 and a sidewall 24 connected to the housing 23. The connecting jack 21 may be provided in the housing 23. The sidewall 24 is movably disposed through the through-hole 101. The socket body 10 is provided with a guide post 25 extending toward the accommodating space 100 along the insertion direction of the plug electrode. One of the socket member 21 and the socket body 10 is provided with a positioning portion 12. The positioning portion 12 may have a positioning groove 120. That is, in some embodiments, the positioning portion 12 may be provided on the socket body 10 or integrally formed with the socket body 10, and the positioning portion 12 may be provided on the socket member 21 or integrally formed with the socket member 21. In other embodiments, the positioning portion 12 may be provided on the socket member 21 or integrally formed with the socket member 21, and the guide post 25 may be provided on the socket body 10 or integrally formed with the socket body 10.

[0053] The guide post 25 is movably inserted into the positioning slot 120 to guide the relative movement of the socket member 20 with respect to the socket body 10 in the direction of insertion of the plug electrode. In this case, the movement range of the socket member 20 can be limited to movement in the vertical direction, thereby reducing the possibility of the socket member 20 moving horizontally during the movement of the safety door 31. As a result, the socket member 20 can be sensitively raised during the movement of the safety door 31 (or during the insertion of the plug electrode).

[0054] Optionally, guide posts 25 are disposed on sidewalls 24 and spaced apart from face shell 23. In a projection direction parallel to the insertion direction of the plug electrodes, the projection of guide posts 25 is at least partially located outside the projections of face shell 23 and sidewalls 24. In this case, guide posts 25 can also serve as position limits. When the jack 20 is raised, the portion of guide posts 25 located outside sidewalls 24 can move to contact the upper shell 13 of the socket body 10, thereby limiting further upward movement of the jack 21.

[0055] Optionally, there are at least two electrode members 11. Each electrode member 11 includes at least one electrode contact portion. The number of connectors 21 is correspondingly at least two, and the at least two connectors 21 correspond one-to-one to the at least two electrode contacts. The two electrode members 11 can be connected to the live wire and the neutral wire, respectively. In this case, the socket 1 can be used for inserting a plug with two pins. The safety door 31 blocks at least part of the electrode contact portion when in the first position.

[0056] Optionally, there are three electrode members 11 (see Figures 2-6). Each electrode member 11 includes an electrode contact portion. There are three sockets 21. The three electrode members 11 can be connected to the live wire, the neutral wire, and the ground wire, respectively. In this case, the socket 1 can be used to insert a plug with three pins.

[0057] It should be noted that when the number of electrode members 11 and the connecting holes 21 changes, the shape of the linkage mechanism and the surface shell can be adaptively changed.

[0058] Optionally, referring to Figures 9, 10, 11 and 12, the number of electrode members 11 is three. Among them, two electrode members 11 each include two electrode contact portions. Another electrode member 11 includes one electrode contact portion. The above-mentioned electrode members 11 each including two electrode contact portions can be used to connect the live wire and the neutral wire, respectively. The electrode member 11 including one electrode contact portion can be used to connect the ground wire. Correspondingly, the number of connectors 21 is five. In this case, the socket 1 can be inserted with a plug having three pins and / or a plug having two pins. Regarding the working principle of the linkage mechanism 30, please refer to the relevant description above and will not be repeated here.

[0059] Optionally, referring to Fig. 9, the socket 1 further comprises a first elastic member 40. The first elastic member 40 is provided on the socket body 10 to drive the socket member 20 to switch from the protruding state to the retracted state.

[0060] Optionally, a first elastic member 40 is disposed between the guide post 25 and the socket body 10 to apply an elastic force to the guide post 25 toward the positioning slot 120, thereby driving the socket 20 downward relative to the socket body 10. In other words, the first elastic member 40 can deform and store energy during the ascent of the socket 20, and then elastically reset and release energy to drive the socket 20 downward relative to the socket body 10 after the plug electrode is removed.

[0061] Specifically, the first elastic member 40 can be elastically connected to the bottom of the positioning groove 120 and the guide column 25. In this case, the first elastic member 40 can be stretched during the ascending process of the jack member 20, and after the plug electrode is pulled out, the first elastic member 40 elastically resets and drives the jack member 20 to descend relative to the socket body.

[0062] The first elastic member 40 can also be positioned between the guide post 25 and the upper shell 13 of the socket body 10. A mounting slot can be provided on the side of the guide post 25 facing the upper shell 13, with the first elastic member 40 positioned within the slot and elastically abutting the upper shell 13. In this case, the first elastic member 40 can be compressed during the ascent of the socket 20. After the plug electrode is removed, the first elastic member 40 elastically returns to its original position, causing the socket 20 to descend relative to the socket body 10.

[0063] In other examples, the socket 1 may not include the first elastic member 40. In this case, when the plug electrode is inserted into the socket 21, the safety door 31 and the socket member 20 can also be driven to rise. When the plug electrode is pulled out, the user can manually press the socket member 20 to reset it.

[0064] Optionally, the cross-sectional shape of the sidewall 24, perpendicular to the direction of elevation of the jack 20, matches the shape of the through-hole 101, so that the through-hole 101 serves to guide the relative movement of the sidewall 24 within the through-hole 101. In other words, in some examples, the through-hole 101 can also guide the relative movement of the jack 20 relative to the socket body 10 in the direction of insertion of the plug electrode, while restricting movement of the jack 20 in other directions. This means that the guide post 25 and the positioning portion 12 are not required.

[0065] Optionally, the socket 1 may further include a first elastic member 40. The first elastic member 40 elastically abuts between the socket member 20 and the socket body 10, and is used to drive the socket member 20 to descend relative to the socket body 10 along the insertion direction of the plug electrode, thereby driving the safety door 31 to reset from the second position to the first position.

[0066] Optionally, as shown in Figure 11 , the socket 1 may include a second elastic member 41. This second elastic member 41 elastically abuts the socket body 10 and the safety door 31, and is used to reset the safety door 31 from the second position to the first position, thereby driving the socket member 20 downward relative to the socket body 10 in the direction of insertion of the plug electrode. In this case, when the plug electrode is removed, the second elastic member 41 releases energy to reset the safety door 31.

[0067] In other embodiments, the socket 1 may not include the second elastic member 41. In this case, since the safety door 31 and the socket member 20 are linked, when the socket member 20 is reset, the elastic member will also be reset.

[0068] Optionally, referring to FIG13 , one of the mounting bracket 15 and the safety door 31 may have a matching groove 50, and the other may have a matching protrusion 51. The matching protrusion 51 is slidably disposed in the matching groove 50 to enable the safety door 31 to move relative to the mounting bracket 15. The extending directions of the matching groove 50 and the matching protrusion 51 may be parallel to the moving direction of the safety door 31.

[0069] Optionally, as shown in FIG13 , a first stopper 500 is provided within the mating groove 50. A second stopper 510 is provided on the mating protrusion 51. The first stopper 500 and the second stopper 510 cooperate to limit the distance between the mating groove 50 and the mating member. The first stopper 500 and the second stopper 510 are elongated, and both extend parallel to the direction of movement of the safety door 31.

[0070] In addition, the jack 20 is further provided with a universal serial bus interface (not shown), which is spaced apart from the connector 21. The universal serial bus interface may also be referred to as a USB interface, and may specifically include at least one of a Standard type-A interface, a Mini type-A interface, a Micro type-A interface, a Standard type-B interface, a Mini type-B interface, a Micro type-B interface, and a Type-C interface.

[0071] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application.
