Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, also not within the protection scope required by the present application.

[0040] Please refer to Figures 1 to 6 An embodiment of the present application provides a power plug 1000, which comprises a fixing seat 100, a rotating plug assembly 200 and an electricity connection assembly 300. The fixing seat 100 has a containing cavity 110, and the containing cavity 110 has an open cavity opening 111. The rotating plug assembly 200 comprises a rotating seat 210, at least two plug pins 220 and at least two conductive connecting pieces 230. The rotating seat 210 is rotatably arranged in the containing cavity 110. The at least two plug pins 220 are arranged on the rotating seat 210, and the at least two plug pins 220 are exposed outside the fixing seat 100 through the cavity opening 111. The at least two conductive connecting pieces 230 are arranged on the rotating seat 210 along the plug-in direction of the plug pins 220, and the at least two conductive connecting pieces 230 are arranged to be insulated from each other. The at least two plug pins 220 and the at least two conductive connecting pieces 230 are electrically connected one by one.

[0041] The electricity connection assembly 300 comprises at least two electricity connection clamping pieces 310. The at least two electricity connection clamping pieces 310 are arranged in the containing cavity 110. The at least two conductive connecting pieces 230 are driven to rotate relative to the at least two electricity connection clamping pieces 310 by the rotating seat 210. The at least two electricity connection clamping pieces 310 correspond to the at least two conductive connecting pieces 230 one by one. The at least two electricity connection clamping pieces 310 are used for clamping the corresponding conductive connecting pieces 230.

[0042] The fixing seat 100 is the basic structure part of the whole power plug 1000, and the containing cavity 110 is arranged in the fixing seat 100. The cavity opening 111 is open, so that other components can be conveniently mounted and subsequently connected with the outside and the like. The containing cavity 110 provides mounting space for the rotating plug assembly 200 and the electricity connection assembly 300, and plays a role of accommodating and positioning each component.

[0043] The at least two conductive connecting pieces 230 are mounted on the rotating seat 210 and exposed outside the fixing seat 100 through the cavity opening 111, and are used for being inserted into a socket to realize physical connection with an external power supply. The at least two conductive connecting pieces 230 are the key contact parts of the power plug 1000 and the external circuit.

[0044] It should be noted that the at least two pins 220 include at least a live pin and a neutral pin, which are respectively connected with a conductive connecting piece 230, wherein the live pin is responsible for transmitting current and providing energy to drive the electrical appliance; the neutral pin is a path for current return, forming a complete circuit to ensure that the current can correctly flow from the power source to the power plug 1000, thereby ensuring the stable flow of current.

[0045] Further, the at least two pins 220 can also include a ground pin, which is connected with a corresponding conductive connecting piece 230. Although the ground pin does not normally participate in the regular power transmission and circuit operation of the electrical appliance, it plays a crucial role in the case of safety hazards such as electrical leakage in the electrical appliance. When the metal shell of the electrical appliance is electrified due to insulation damage or other reasons, the ground pin provides a direct and safe path for the accidental leakage of current to the ground, thereby avoiding electric shock when the operator touches the device shell and greatly ensuring the safety of personnel and equipment.

[0046] In this embodiment, the power contact clamping pieces 310 are also at least two, which are arranged on the fixed seat 100 in the plug-in direction of the pins 220 and are insulated from each other. The power contact clamping pieces 310 are electrically connected one-to-one with the pins 220, thereby serving as a bridge for conducting current between the pins 220 and the power contact assembly 300, and ensuring that the current can be smoothly transmitted from the pins 220 to the power contact assembly 300.

[0047] Preferably, the at least two conductive connecting pieces 230 have the same structure and shape, thereby reducing the number of parts and the production mold for manufacturing the conductive connecting pieces 230. Correspondingly, the at least two power contact clamping pieces 310 can also be set to have the same structure and shape, thereby reducing the number of parts and the production mold for manufacturing the power contact clamping pieces 310.

[0048] The rotating seat 210 is rotatably arranged in the accommodating cavity 110 of the fixed seat 100. When the pins 220 are rotated by external force, the rotating seat 210 is rotated, and the conductive connecting pieces 230 are rotated relative to the power contact clamping pieces 310 under the driving of the rotating seat 210. Due to the clamping action of the power contact clamping pieces 310 on the conductive connecting pieces 230, the two always maintain close physical contact and electrical connection. Compared with the traditional simple contact type connection, the power contact clamping pieces 310 can provide a larger contact area and more stable contact pressure, effectively preventing displacement and loosening of the connection part during the rotation of the pins 220, greatly reducing the risk of poor contact, avoiding power failure caused by poor contact, reducing the possibility of arc spark generation, and ensuring that the electrical equipment can continuously and stably obtain power supply, thereby greatly reducing the hidden danger of serious safety accidents such as fire or explosion when using the power plug 1000.

[0049] Please refer to Figure 5 andFigure 7 In some embodiments, each conductive connecting piece 230 has a connecting portion 231 exposed outside the rotating seat 210, and each electrical contact clamping piece 310 is provided with a clamping groove 311 on one side facing the corresponding connecting portion 231, the connecting portion 231 is clamped in the corresponding clamping groove 311 and is electrically connected with the corresponding electrical contact clamping piece 310.

[0050] The connecting portion 231 of the conductive connecting piece 230 extends outward from the rotating seat 210 and becomes a key part for physical contact and electrical conduction with the electrical contact clamping piece 310. The exposed part facilitates the cooperation operation with the electrical contact clamping piece 310, and when the rotating seat 210 drives the conductive connecting piece 230 to rotate, the connecting portion 231 can relatively flexibly move in the corresponding structure of the electrical contact clamping piece 310 to maintain the electrical connection state.

[0051] Because the connecting portion 231 and the inner wall of the clamping groove 311 are in close contact, when the current is conducted from the pin 220 to the conductive connecting piece 230, it is transmitted along the connecting portion 231 to the inner wall of the clamping groove 311 which is in close contact with it, and then conducted to the subsequent circuit through the electrical contact clamping piece 310, realizing a complete and stable electrical conduction process. This way of realizing electrical conduction through close contact guarantees the reliability of contact by the clamping structure, maximally reduces the problems of increased resistance, heating and arc caused by poor contact, and guarantees the electrical conductivity and safety of the power plug 1000 as a whole.

[0052] Please refer to Figure 2 and Figure 7 The electrical contact clamping piece 310 comprises a first clamping piece 312 and a second clamping piece 313 connected with each other, and the clamping groove 311 is formed between the first clamping piece 312 and the second clamping piece 313.

[0053] At least one of the first clamping piece 312 and the second clamping piece 313 is elastic, so that the connecting portion 231 is elastically clamped in the corresponding clamping groove 311.

[0054] The electrical contact clamping piece 310 is composed of the first clamping piece 312 and the second clamping piece 313 connected with each other, and the clamping groove 311 for clamping the connecting portion 231 of the conductive connecting piece 230 is formed by the cooperation of the first clamping piece 312 and the second clamping piece 313. The first clamping piece 312 and the second clamping piece 313 are arranged relatively in position to clamp the connecting portion 231, thereby realizing the fixation and electrical connection thereof. The shape and size of the first clamping piece 312 and the second clamping piece 313 are adapted to the connecting portion 231, ensuring that the connecting portion 231 can be accurately and stably placed in the clamping groove 311 formed between the two.

[0055] At least one of the first clamping piece 312 and the second clamping piece 313 is elastic, so that the first clamping piece 312 and the second clamping piece 313 can be deformed to a certain extent when subjected to external force, and can return to the original state after the external force disappears. For example, if the first clamping piece 312 is elastic, when the connecting part 231 of the conductive connecting piece 230 is inserted into the clamping groove 311, the first clamping piece 312 will be elastically deformed outward under the extrusion of the connecting part 231, thereby leaving a space for the connecting part 231; when the connecting part 231 is completely inserted, the first clamping piece 312 restores to the surface of the connecting part 231 by its own elastic restoring force, realizing the effect of elastic clamping.

[0056] Because at least one of the first clamping piece 312 and the second clamping piece 313 is elastic, the clamping groove 311 can realize self-adaptive adjustment to the connecting part 231 within a certain tolerance range of different size specifications. Even if there is a slight deviation in the size of the connecting part 231 during the production process, or the size of the connecting part 231 changes due to wear and tear and other reasons as the use time increases and the number of insertions and extractions increases, the elastic clamping groove 311 can still adjust the clamping force and the fitting degree of the connecting part 231 through the elastic deformation of the first clamping piece 312 and the second clamping piece 313, to ensure tight and stable contact.

[0057] Moreover, during the use of the power plug 1000, whether it is normal insertion and extraction operation, or slight displacement or rotation of the rotating seat 210 and the conductive connecting piece 230 due to external factors (such as vibration, occasional external force pulling, etc.), the power clamping piece 310 can still play a role. When the connecting part 231 has a small amplitude of position change in the clamping groove 311, the elastic first clamping piece 312 and the second clamping piece 313 will produce corresponding deformation to adapt to the change, and always maintain sufficient pressure on the connecting part 231, so that the connecting part 231 and the inner wall of the clamping piece maintain good electrical contact. This dynamic elastic adjustment ensures that the current can be continuously and stably conducted from the connecting part 231 to the power clamping piece 310, avoiding problems such as power failure and arc generation caused by poor contact, and ensuring the electrical conductivity of the entire power plug 1000 and the normal operation of the electrical equipment.

[0058] In this embodiment, the conductive connecting piece 230 and the power clamping piece 310 can be made of materials with good electrical conductivity, such as metal materials such as copper, which can rely on the elasticity of the power clamping piece 310 itself to tightly clamp the connecting part 231 in the clamping groove 311, ensuring that the connecting part 231 can stably stay in the clamping groove 311 even when the rotating seat 210 drives the conductive connecting piece 230 to rotate, without displacement or loosening that affects electrical connection.

[0059] Please continue to refer toFigure 7 In some embodiments, the first clamping piece 312 and the second clamping piece 313 each include a straight segment 314 and a bent segment 315 connected to each other, the bent segment 315 of the first clamping piece 312 is connected to the bent segment 315 of the second clamping piece 313 through a connecting segment 316, and the straight segment 314 of the first clamping piece 312 is arranged opposite to the straight segment 314 of the second clamping piece 313 and approaches each other.

[0060] The two straight segments 314 are arranged opposite to each other and approach each other, forming a clamping groove 311, which plays a role of clamping the conductive connecting piece 230. The two straight segments 314 have a relatively regular and straight shape, which can provide a relatively stable and large-area contact surface. When the connecting part 231 of the conductive connecting piece 230 is placed in the clamping groove 311, the inner surface of the straight segment 314 will be in close contact with the connecting part 231, ensuring good contact effect and helping to stabilize the conduction of current. Moreover, the opposite and approaching arrangement makes the clamping groove 311 form a relatively regular and closed space in this area, which can more effectively limit the movement of the connecting part 231 in the horizontal direction and enhance the fixation of the connecting part 231.

[0061] The existence of the bent segment 315 changes the overall shape of the first clamping piece 312 and the second clamping piece 313. Through bending, the relative positional relationship between the first clamping piece 312 and the second clamping piece 313 and the spatial layout of the whole power connection clamping piece 310 can be better adjusted, creating favorable conditions for subsequent cooperation with other components and realization of its own functions. For example, the bent segment 315 can make the first clamping piece 312 and the second clamping piece 313 have a certain stretching or shrinking space in a certain direction, which is convenient for coping with different external force conditions or adapting to different structural requirements during installation and use.

[0062] The bent segment 315 of the first clamping piece 312 is connected to the bent segment 315 of the second clamping piece 313 through the connecting segment 316, which plays a key role in connecting the two clamping pieces into a whole, and it ensures that the relative positional relationship between the first clamping piece 312 and the second clamping piece 313 remains stable, so that the whole power connection clamping piece 310 has a certain structural rigidity and integrity.

[0063] Please continue to refer to Figure 6 In some embodiments, the conductive connecting piece 230 is arranged in a ring shape, and the conductive connecting piece 230 is provided with a connecting end 232 extending into the ring-shaped ring, and the connecting end 232 is connected to one end of the pin 220.

[0064] The conductive connecting piece 230 adopts a design form of a ring-shaped sheet, and the ring-shaped structure presents a closed ring in space, having good symmetry and stability. The conductive connecting piece 230 can be uniformly distributed around the central axis of the rotating seat 210, and when the rotating seat 210 drives rotation, each part is relatively uniformly stressed, and is not prone to deformation, damage and the like due to uneven local stress.

[0065] The connecting end 232 is located in the inner region of the ring, extends from the main body of the ring-shaped structure to the inside, and is connected to one end of the pin 220. Such a layout makes the connection between the pin 220 and the conductive connecting piece 230 more compact and concealed, and makes the overall structure layout more regular and orderly, and also reduces the possibility of connection loosening or damage due to direct influence of external factors (such as collision, pulling, etc.) on the connection part, thereby playing a certain role in protecting the connection point.

[0066] In some embodiments, the connecting end 232 and one end of the pin 220 can adopt a plug-in buckle manner. When assembling the plug, it is only necessary to align one end of the pin 220 with the connecting end 232 of the conductive connecting piece 230, and then insert it into the corresponding buckle structure to complete the connection, which is convenient and simple in assembly process.

[0067] Please refer to Figure 2 , Figure 5 and Figure 6 In some embodiments, the rotating seat 210 includes a pin seat 211 and at least one isolation seat 212, the pin seat 211 is connected with the at least one isolation seat 212, and the pin 220 is arranged on the pin seat 211.

[0068] The outer wall of the isolation seat 212 is provided with at least one outwardly protruding annular flange 213, and the annular flange 213 is located between the adjacent two conductive connecting pieces 230, and is used for separating the at least two conductive connecting pieces 230.

[0069] In this embodiment, the pin seat 211 provides a stable mounting basis for the pin 220, ensures that the pin 220 can accurately dock with an external socket during use, and when the rotating seat 210 rotates, the pin seat 211 drives the pin 220 to rotate together, so that the pin 220 can be inserted or pulled out of the socket at a suitable angle and position, maintaining normal plug-in and pull-out operations and current conduction functions.

[0070] The outer wall of the isolation seat 212 is provided with the outwardly protruding annular flange 213, which can effectively separate the adjacent conductive connecting pieces 230, ensure that each conductive connecting piece 230 is in a mutually insulated state, avoid abnormal conditions such as short circuit of current between different conductive connecting pieces 230, and thus ensure the electrical safety and normal current conduction order of the entire power plug 1000.

[0071] It should be understood that the foot seat 211 and the isolation seat 212 can be detachably connected, for example, a snap connection, which not only facilitates the use of the user, but also allows the foot seat 211 and the isolation seat 212 to be quickly disassembled and assembled, and when replacement or maintenance is required, the foot seat 211 can be quickly disassembled from the isolation seat 212, improving the convenience of use and the efficiency of maintenance.

[0072] Please refer to Figure 2 , Figure 5 and Figure 8 In some embodiments, the power plug 1000 further comprises a mounting seat 214 arranged in the accommodating cavity 110 and spaced apart from the isolation seat 212, and the mounting seat 214 is provided with at least two spaced apart mounting grooves 215 along the plug-in direction of the pin 220, and each mounting groove 215 is used to install an electrical contact holder 310.

[0073] Among them, the isolation seat 212 is mainly used to separate the conductive connecting pieces 230, to ensure the insulation between the conductive connecting pieces 230 and the independence of current conduction, and the mounting seat 214 provides a mounting position for the electrical contact holder 310, and the two are spaced apart to avoid mutual interference and to enable the respective functions to be better achieved, for example, to prevent accidental contact between components due to too close distance, affecting electrical safety or normal clamping and electrical connection of the electrical contact holder 310 to the conductive connecting piece 230, etc.

[0074] The mounting seat 214 is provided with at least two spaced apart mounting grooves 215 along the plug-in direction of the pin 220, and each mounting groove 215 is correspondingly used to install an electrical contact holder 310. This one-to-one mounting method enables the electrical contact holder 310 to be accurately and stably positioned in the mounting groove 215, ensuring that the electrical contact holder 310 does not move or dislocate randomly during use, thereby ensuring that the relative positional relationship between the electrical contact holder 310 and the conductive connecting piece 230 remains stable, which is conducive to maintaining reliable electrical connection.

[0075] In this embodiment, the design of the mounting seat 214 and the mounting groove 215 enables the layout of the components inside the power plug 1000 to be more regular and orderly, fully utilizes the space inside the accommodating cavity 110, avoids cluttered accumulation or unreasonable space occupation between components, improves the compactness and rationality of the internal structure of the entire power plug 1000, helps to realize more functions in a limited space, and also facilitates assembly operation during production and manufacturing process, improving production efficiency.

[0076] In some embodiments, the mounting seat 214 is provided with at least one avoiding groove 216 along the plug-in direction of the pin 220, and the annular flange 213 is at least partially accommodated in the avoiding groove 216.

[0077] The annular flange 213 is at least partially accommodated in the avoiding groove 216, so that the isolation seat 212 and the mounting seat 214 form a nested form in space. The outwardly protruding part of the annular flange 213 can be accurately embedded in the avoiding groove 216, so that the isolation seat 212 and the mounting seat 214 are more closely combined in structure, and at the same time, it is ensured that there is no conflict in spatial layout, avoiding affecting the normal assembly and function realization of the internal structure of the power plug 1000 due to mutual interference.

[0078] The design of accommodating the annular flange 213 by the avoiding groove 216 makes the isolation seat 212 play its role of separation in the correct position, preventing short circuit and other electrical faults between the conductive connecting pieces 230. At the same time, it is also helpful to maintain the accurate correspondence and good electrical connection state between the power contact clamping piece 310 and the conductive connecting piece 230, so that the spatial positions of the components can be accurately matched, and the original conductive path and insulation layout will not be damaged due to space conflict, thereby guaranteeing the current conduction function and electrical safety of the power plug 1000 as a whole.

[0079] In some embodiments, the outer peripheral wall of the rotating seat 210 is provided with an annular protruding rib 217, which is used to abut the inner side edge of the cavity opening 111. In the assembly and use process of the power plug 1000, the annular protruding rib 217 abuts the inner side edge of the cavity opening 111, which can effectively limit the movement of the rotating seat 210 along the plug-in direction of the plug 220 (that is, the axial direction). For example, in normal use, even if the plug is pulled by external force, the force during plugging, etc., the abutment of the annular protruding rib 217 and the edge of the cavity opening 111 can prevent the rotating seat 210 from being pulled out of the accommodating cavity 110, maintain the relative stable connection and cooperation relationship between the components, and guarantee the integrity of the structure of the entire power plug 1000 and the normal function of each component.

[0080] In addition, one of the conductive connecting piece 230 and the rotating seat 210 is provided with a limiting groove 233, and the other is provided with a limiting rib 218 matched with the limiting groove 233, and the limiting rib 218 and the limiting groove 233 are engaged to connect the conductive connecting piece 230 and the rotating seat 210.

[0081] The reliable connection between the conductive connecting piece 230 and the rotating seat 210 is realized through the clamping cooperation of the limiting ribs 218 and the limiting grooves 233. When assembling the power plug 1000, the limiting ribs 218 are inserted into the limiting grooves 233, so that the conductive connecting piece 230 is stably installed on the rotating seat 210, the position of the conductive connecting piece 230 is determined, and the conductive connecting piece 230 is prevented from being randomly moved or misaligned on the rotating seat 210. For example, during the rotation of the rotating seat 210, the cooperation of the limiting grooves 233 and the limiting ribs 218 can ensure that the conductive connecting piece 230 moves synchronously with the rotating seat 210, the relative position relationship between the conductive lines is maintained stable, and the current can be conducted along the established path, and problems such as open circuit or short circuit caused by displacement of the conductive connecting piece 230 are avoided.

[0082] Compared with some connection methods such as complex screw fixing and welding, the clamping cooperation operation is more convenient and fast, workers only need to insert the limiting ribs 218 into the limiting grooves 233 to complete the connection, the requirement for the operation skill of workers is reduced, and the speed and efficiency of assembly are improved. Moreover, since the shape and size of the limiting grooves 233 and the limiting ribs 218 are accurately matched, the installation position of the conductive connecting piece 230 on the rotating seat 210 is accurate, the assembly precision is improved, and product quality problems caused by assembly errors are reduced.
