[0040] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0041] With the development of science and technology and the improvement of people's quality of life, people's material life is becoming more and more abundant, and the electrical equipment used is also in demand. Electricity has become an indispensable and important energy source in people's lives, especially at home, where various new household appliances are emerging in an endless stream.

[0042] like Figure 1 As shown, this embodiment provides a plug, which includes a shell 1 and a plurality of pin assemblies 2. The pin assemblies 2 are arranged on the shell 1 and correspond one-to-one with the jacks of the corresponding socket. When the plug is plugged into the socket, the pin assemblies 2 need to be inserted into the corresponding jacks respectively.

[0043] However, the working voltage of household appliances is much higher than the safety voltage of the human body. When children plug the plug into the socket, they may accidentally touch the pins and cause electric shock accidents, resulting in serious consequences. Currently, neither the plug nor the socket has a structure or function to prevent children from accidentally touching it, which brings safety hazards to the use of the plug.

[0044] like Figure 1 to Figure 5 As shown, in order to solve the above problems, among the multiple pin assemblies 2 provided in this embodiment, at least one pin assembly 2 includes a rotating pin 21 and a driving member 22, the rotating pin 21 is inserted into the shell 1 and can rotate relative to the shell 1, the driving member 22 is movably arranged on the shell 1, and the driving member 22 is configured to drive the rotating pin 21 to rotate so as to change the angle between the rotating pin 21 and the corresponding socket on the socket.

[0045] The rotating pin 21 has a rotating axis, and the moving direction of the driving member 22 is parallel to the rotating axis of the rotating pin 21. The driving member 22 can drive the rotating pin 21 to rotate around the rotating axis, thereby changing the angle between the rotating pin 21 and the corresponding socket on the socket. Since the plug has multiple pin assemblies 2, when at least one pin assembly 2 has a rotating pin 21 and the rotating pin 21 cannot be inserted into the socket, other pins cannot be inserted into the corresponding sockets, thereby preventing children from accidentally touching the pins when plugging the plug into the socket.

[0046] The plug can change the angle between the rotating pin 21 and the socket through the driving member 22 to prevent children from accidentally touching the pin and getting an electric shock, has a fool-proof effect, and improves the safety of the plug.

[0047] It is worth noting that the pin assembly 2 without the rotating pin 21 includes a fixed pin, which is fixedly arranged on the shell 1, so the relative angle between the fixed pin and the shell 1 will not change. As long as the angle of the rotating pin 21 is matched with the corresponding socket of the socket, the plug can be plugged into the socket; as long as the angle of at least one rotating pin 21 changes, so that the rotating pin 21 cannot be matched with the corresponding socket of the socket, it can be ensured that the plug cannot be inserted into the socket, thereby preventing children from accidentally touching the pin and getting an electric shock.

[0048] It is worth noting that the rotating pin 21 has a plug-in portion 211, which is inserted into the socket of the socket, and the cross-section of the plug-in portion 211 is non-circular, so as to avoid the problem that the rotating pin 21 can be inserted into the socket regardless of the angle of rotation of the rotating pin 21. In this embodiment, the cross-section of the plug-in portion 211 is a rectangle, and in other embodiments, the cross-section of the plug-in portion 211 can also be other shapes, such as an ellipse, an oblong, a rhombus, etc.

[0049] For ease of assembly, the housing 1 includes a bottom shell 11 and an upper cover 12 . The bottom shell 11 has an opening. The upper cover 12 can close the opening to form a cavity with the bottom shell 11 . A cable 3 connected to the pin assembly 2 is disposed in the cavity.

[0050] like Figure 3 , Figure 5 to Figure 7 As shown, a driving inclined surface 221 is provided at one end of the driving member 22 facing the rotating pin 21, and a driven protrusion 212 is convexly provided on the rotating pin 21. The driving inclined surface 221 extends along the circumference of the driving member 22 and is inclinedly arranged, and the driven protrusion 212 can slide along the driving inclined surface 221. When the driving member 22 is pressed toward the rotating pin 21, the driving inclined surface 221 will generate a force on the driven protrusion 212 to rotate the rotating pin 21 relative to the driving member 22. When the plug is unplugged from the socket, only the driving member 22 needs to be pressed to prevent the plug-in portion 211 of the rotating pin 21 from being inserted into the corresponding socket, thereby ensuring safety.

[0051] The driving member 22 is provided with a driving protrusion 223 , and a side of the driving protrusion 223 facing the rotating pin 21 forms the driving inclined surface 221 . The driving protrusion 223 cooperates with the driven protrusion 212 , thereby realizing the operation of driving the rotating pin 21 to rotate by pressing.

[0052] like Figure 8 As shown, the housing 1 is provided with a locking sleeve 13, the pin assembly 2 is inserted into the locking sleeve 13 and can move along the axial direction of the locking sleeve 13, and a retaining rib 131 is protruded from the inner wall of the locking sleeve 13. The retaining rib 131 corresponds to the driving inclined surface 221 and can abut against the rotating pin 21 to prevent the rotating pin 21 from rotating. When the driving member 22 is pressed, the rotating pin 21 can pass over the retaining rib 131.

[0053] like Figure 5 As shown, the retaining rib 131 can prevent the rotating pin 21 from rotating, which is equivalent to limiting the rotating pin 21 so that the rotating pin 21 can be kept at an angle. Whether it is to prevent the plug-in portion 211 from being inserted into the socket or to insert the plug-in portion 211 into the socket during normal use, the stable use of the rotating pin 21 can be ensured. Figure 6 and Figure 7 As shown, when the operator presses the driving member 22, the driving member 22 pushes the rotating pin 21 to move along the axis of the rotating shaft of the rotating pin 21. When the rotating pin 21 passes over the retaining rib 131, the rotating pin 21 can rotate along the driving inclined surface 221 to achieve the switching of the angle of the plug-in portion 211.

[0054] Among them, the locking sleeve 13 is located in the cavity and fixedly connected to the bottom shell 11. The retaining rib 131 can be connected to the bottom plate of the bottom shell 11 or spaced apart from the bottom plate of the bottom shell 11. However, the top of the retaining rib 131 needs to be spaced apart from the upper cover 12, and the spacing size allows the rotating pin 21 to pass over the retaining rib 131 when rotating.

[0055] In this embodiment, the retaining rib 131 prevents the rotation of the rotating pin 21 by abutting against the driven protrusion 212 in the circumferential direction. The driven protrusion 212 realizes the two functions of driving the rotating pin 21 to rotate and preventing the rotating pin 21 from rotating, which greatly simplifies the structure of the rotating pin 21 and saves space in the housing 1. It can be understood that in some embodiments, the rotating pin 21 can also be provided with a special protrusion structure to cooperate with the retaining rib 131 to prevent the rotating pin 21 from rotating.

[0056] like Figure 3 As shown, the side wall of the driving member 22 is recessed with a guide groove 222, and one end of the guide groove 222 opens to the driving inclined surface 221, and the retaining rib 131 is partially located in the guide groove 222. The retaining rib 131 can limit the rotation of the driving member 22 through the guide groove 222, so that the driving member 22 can only move along the pressing direction, so the position of the driving inclined surface 221 of the driving member 22 in the circumferential direction will not change, and the rotation angle of the rotating pin 21 can be controlled.

[0057] In this embodiment, the slope of the end surface of the retaining rib 131 facing the rotating pin 21 is the same as the slope of the driving inclined surface 221. This arrangement allows the end surface of the retaining rib 131 to overlap with the driving inclined surface 221 when the driving member 22 is pressed, so that when the driven protrusion 212 passes over the retaining rib 131, the movement of the driven protrusion 212 is smoother.

[0058] like Figure 5 to Figure 7As shown, the pin assembly 2 also includes a first elastic member 23, one end of the first elastic member 23 abuts against the shell 1, and the other end of the first elastic member 23 abuts against the rotating pin 21. The first elastic member 23 is configured to drive the rotating pin 21 to move in a direction away from the upper cover 12. When the driving member 22 is pressed, the rotating pin 21 is always abutted against the driving member 22, so that the driven protrusion 212 can move along the driving inclined surface 221.

[0059] In this embodiment, the rotating pin 21 is provided with a plurality of driven protrusions 212, and the plurality of driven protrusions 212 are connected end to end along the circumferential direction of the rotating pin 21. When the driving member 22 is pressed to drive the rotating pin 21 to rotate, the driven protrusions 212 of the rotating pin 21 move along the corresponding driving inclined surface 221, and when the driven protrusions 212 move to the bottom of the driving inclined surface 221, the rotating pin 21 stops rotating. At this time, the driving member 22 is moved in the reverse direction, and the rotating pin 21 is continuously rotated, so that the next section of the driven protrusions 212 abuts against the retaining rib 131, so that the driving member 22 can drive the rotating pin 21 to rotate continuously.

[0060] It is worth noting that since the retaining rib 131 is located in the middle position of the driving inclined surface 221, when the driving inclined surface 221 rotates the rotating pin 21 through the driven protrusion 212, the next driven protrusion 212 will abut the driving protrusion 223. When the driving member 22 moves in the direction away from the rotating pin 21, the rotating pin 21 and the driving member 22 have no relative movement in the circumferential direction. At this time, pressing the driving member 22 will not be able to continue to drive the rotating pin 21 to rotate. The operator needs to manually rotate the rotating pin 21, which is inconvenient.

[0061] To solve the above problem, a driven slope 213 is provided at one end of the driven protrusion 212 facing the driving member 22. The inclination direction of the driven slope 213 is the same as the inclination direction of the driving slope 221. The end of the retaining rib 131 can abut against the driven slope 213 and slide relative to the driven slope 213.

[0062] When the driven protrusion 212 slides to the bottom end along the driving inclined surface 221 and abuts against the next driving protrusion 223, as the driving member 22 moves away from the rotating pin 21, the first elastic member 23 drives the rotating pin 21 to move so that the driven inclined surface 213 abuts against the retaining rib 131. At this time, the end of the retaining rib 131 slides relative to the driven inclined surface 213, thereby driving the driven protrusion 212 to rotate, so that the driven inclined surface 213 partially overlaps with the driving inclined surface 221 in the axial direction. At this time, continue to press the driving member 22 to drive the rotating pin 21 to rotate through the driven inclined surface 213.

[0063] In this embodiment, the driving member 22 includes a plurality of driving protrusions 223 arranged along the circumferential direction, and each driving protrusion 223 forms a driving inclined surface 221 on a side facing the rotating pin 21, and the plurality of driving protrusions 223 are connected end to end along the circumferential direction of the rotating pin 21. The plurality of driving inclined surfaces 221 can drive the rotating pin 21 to rotate through the plurality of driven protrusions 212, so that the driving force on the rotating pin 21 in the circumferential direction is evenly distributed, and the eccentric force causes the rotating pin 21 to deviate and increase the rotation resistance or get stuck.

[0064] It is worth noting that the locking sleeve 13 is provided with a retaining rib 131 corresponding to each driving protrusion 223 .

[0065] like Figure 5 to Figure 7 As shown, the pin assembly 2 further includes a second elastic member 24, which is configured to drive the driving member 22 to move in a direction away from the rotating pin 21. The second elastic member 24 can reset the driving member 22 when it is not pressed. At this time, the driving member 22 is separated from the rotating pin 21, and the end of the retaining rib 131 slides relative to the driven inclined surface 213, thereby driving the driven protrusion 212 to rotate, so that the driven inclined surface 213 partially overlaps with the driving inclined surface 221 in the axial direction, so that each time the driving member 22 is pressed, the rotating pin 21 can be driven to rotate. In addition, the second elastic member 24 improves the relative stability between the driving member 22 and the housing 1, so that the driving member 22 will not shake relative to the housing 1, and it is also convenient for the operator to press the next time.

[0066] Specifically, the second elastic member 24 can be disposed between the driving member 22 and the rotating pin 21, or between the housing 1 and the driving member 22, as long as the driving member 22 can be moved away from the rotating pin 21. In this embodiment, the second elastic member 24 is located between the housing 1 and the driving member 22.

[0067] In this embodiment, the driving member 22 has three driving protrusions 223, and the rotating pin 21 has three driven protrusions 212, so each time the driving member 22 is pressed, the rotating pin 21 will rotate 120 degrees. It is worth noting that the driving protrusions 223 and the driven protrusions 212 can also be other numbers, such as four, six or twelve, etc. Correspondingly, each time the driving member 22 is pressed, the rotating pin 21 will rotate 90 degrees, 60 degrees or 30 degrees.

[0068] In order to further improve the safety of the plug, a pressing groove is provided on the side of the housing 1 away from the rotating pin 21 extending out of the housing 1, and the driving member 22 partially extends out of the housing 1, and the part of the driving member 22 extending out of the housing 1 is completely located in the pressing groove. This arrangement ensures that the driving member 22 does not protrude from the surface of the housing 1, greatly reduces the probability that a child accidentally touches the driving member 22 to change the angle of the rotating pin 21, and avoids the situation where a child accidentally touches the plug and causes it to be inserted into the socket. In this embodiment, the pressing groove is provided on the bottom shell 11.

[0069] It is understandable that the plug usually includes a plurality of pin assemblies 2, the plug of a low-power electrical appliance includes two pin assemblies 2, and the plug of a high-power electrical appliance includes three pin assemblies 2. Among them, at least one pin assembly 2 has a rotating pin 21, which can play a fool-proof role. Of course, in order to be more secure, all the pin assemblies 2 can also have rotating pins 21. In this case, the angle between each rotating pin 21 and the socket of the socket needs to be adjusted correctly before plugging can be performed. It is worth noting that the plug can also have more than three pin assemblies 2, which will not be repeated here.

[0070] like Fig. 9 As shown, the cable 3 includes a conductive ring 31, the rotating pin 21 includes a connecting rod 214, the connecting rod 214 is partially located in the driving member 22, the cable 3 is inserted into the driving member 22, and the conductive ring 31 is sleeved on the connecting rod 214 and electrically connected to the connecting rod 214. When the rotating pin 21 rotates, the connecting rod 214 rotates in the conductive sleeve, and the connecting rod 214 is always in contact with the conductive sleeve, thereby ensuring the reliability of the electrical connection between the rotating pin 21 and the cable 3.

[0071] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
