Description

Technical Field

[0001] The utility model relates to the technical field of plugs, and particularly relates to a power plug. Background Art

[0002] As an electrical connection device, the power plug plays an important role in electrically connecting electrical equipment to a power socket. In modern society, with the popularization and wide application of various electrical equipment, such as household appliances, office equipment, industrial equipment, etc., the power plug has become an essential electrical accessory.

[0003] The pins and wires of existing power plugs are fixedly connected together, and the pins cannot rotate, which limits the direction of inserting the pins into the socket. In order to insert the pins into the socket, the wires have to be twisted, which will bring potential safety hazards after long-term use. Moreover, when the space where the socket is located is too small, it is more difficult for the pins to align with the sockets on the socket, making it inconvenient to use.

[0004] To solve the above problems, some rotatable power plugs have emerged on the market. By setting pin electrodes and pins that can rotate relative to the pin electrodes, users are allowed to freely adjust the direction and angle of the pins according to needs, so as to better adapt to different positions of power sockets and usage scenarios. However, the contact between the pins and the pin electrodes of these power plugs is all through point contacts. During the rotation process, it is easy to cause the contact surface between the pins and the plug electrodes to be too small, resulting in poor contact between the pins and the pin electrodes, increased contact resistance, and thus heat generation at the contact part of the pin electrodes.

[0042] Please refer to Figures 1 to 4 , the present utility model provides a power plug 100, which includes a fixed seat 10, a rotating pin assembly 20, and a power connection assembly 30. The fixed seat 10 has a receiving cavity 11, and the receiving cavity 11 has an open cavity opening 12;

[0043] The rotating pin assembly 20 includes a rotating seat 21, at least two pins 22, and at least two conductive connectors 23. The rotating seat 21 is rotatably disposed in the receiving cavity 11. At least two pins 22 are disposed on the rotating seat 21, and at least two pins 22 are exposed outside the fixed seat 10 through the cavity opening 12. At least two conductive connectors 23 are disposed on the rotating seat 21, and at least two conductive connectors 23 are insulated and separated from each other. At least two pins 22 are electrically connected to at least two conductive connectors 23 in a one-to-one correspondence.

[0044] It should be noted that at least two pins 22 at least include a live wire pin and a neutral wire pin, which are respectively connected to a conductive connector 23. Among them, the live wire pin is responsible for transmitting current and providing energy to drive the electrical appliance; the neutral wire pin is the path for current to flow back, forming a complete circuit to ensure that the current can correctly flow from the power source to the power plug 100, ensuring the stable flow of current.

[0045] In this embodiment, the structures and shapes of at least two conductive connectors 23 are the same, reducing the number of parts and the production molds for manufacturing the conductive connectors 23.

[0046] The power connection assembly 30 includes at least two power connection members 31. At least two power connection members 31 are disposed in the receiving cavity 11. At least two power connection members 31 are electrically connected to at least two conductive connectors 23 in a one-to-one correspondence. At least two conductive connectors 23 slide relative to at least two power connection members 31 under the drive of the rotating seat 21.

[0047] In this embodiment, the electrical connectors 31 and the conductive connecting members 23 are connected in a sliding manner, allowing the conductive connecting members 23 to slide relative to the electrical connectors 31, so as to adapt to different electrical connection requirements and provide a flexible power transmission method. Through this design, the rotary plug can adapt to power connections at different angles and positions, enhancing its applicability and convenience of use. In addition, this sliding connection method also helps to reduce friction and resistance during electrical connection, improving the stability and reliability of the electrical connection.

[0048] Among them, each conductive connecting member 23 has a first arc-shaped contact surface 231, and each electrical connector 31 has a second arc-shaped contact surface 311 adapted to the first arc-shaped contact surface 231. The first arc-shaped contact surface 231 is in electrical contact with the second arc-shaped contact surface 311 to realize the electrical connection between the conductive connecting member 23 and the electrical connector 31.

[0049] In this embodiment, the contact surfaces between the conductive connecting member 23 and the electrical connector 31 are designed as arcs, which can provide better electrical conductivity and stability. Specifically, this design has the following advantages:

[0050] 1. Maintaining a large effective contact area: When the first arc-shaped contact surface 231 of the conductive connecting member 23 contacts the second arc-shaped contact surface 311 of the electrical connector 31, a relatively large effective contact area can be formed. This design helps to ensure the uniform distribution of current, reduce hot spots and resistance, thereby improving the electrical conductivity efficiency and stability.

[0051] 2. Improving the conduction rate: The design of the arc-shaped contact surface can increase the number of contact points and reduce the contact resistance, thereby improving the conduction rate. This design helps to reduce the voltage drop and improve the current transmission efficiency.

[0052] 3. Enhancing mechanical stability: The design of the arc-shaped contact surface not only has advantages in electrical performance, but also can enhance mechanical stability. This design can better adapt to mechanical vibration and thermal expansion, reduce the situation of poor contact or disconnection, and thus ensure the reliability of the connection.

[0053] In summary, the electrical contact between the first arc-shaped contact surface 231 and the second arc-shaped contact surface 311 realizes the surface contact between the conductive connecting member 23 and the electrical connector 31, increasing the electrical contact area. In this way, when the plug rotates relative to the fixed seat 10, the conductive connecting member 23 and the electrical connector 31 maintain surface-to-surface contact, avoiding poor contact and increased contact resistance between the two, which may cause the electrode contact part of the pin 22 to heat up, and thus extending the service life of the power plug 100.

[0054] In some embodiments, the conductive connecting member 23 has an annular structure. The conductive connecting member 23 is sleeved outside the rotating seat 21, and the surface of the conductive connecting member 23 facing away from the rotating seat 21 forms the first arc-shaped contact surface 231.

[0055] In this embodiment, the design of the conductive connecting member 23 in a ring structure allows the conductive connecting member 23 to be closely sleeved outside the rotating seat 21, ensuring the tightness and stability of the connection. It not only guarantees the effective transmission of electrical signals or current, but also adapts to the shape of the rotating seat 21, enabling the entire power plug 100 to maintain a stable electrical connection during the rotation process. In addition, a first arc-shaped contact surface 231 is formed on the surface of the conductive connecting member 23 facing away from the rotating seat 21, which helps to reduce the friction and wear between the conductive connecting member 23 and the power receiving member 31 during the rotation process, while ensuring good electrical contact.

[0056] Please refer to Figure 4 , in some embodiments, the power receiving member 31 includes an arc-shaped power receiving portion 312. A second arc-shaped contact surface 311 is formed on the surface of the arc-shaped power receiving portion 312 facing the conductive connecting member 23. The arc-shaped power receiving portion 312 has elasticity, and the arc-shaped power receiving portion 312 is elastically sleeved outside the conductive connecting member 23 so that the first arc-shaped contact surface 231 is in contact with the second arc-shaped contact surface 311 to achieve electrical contact.

[0057] In this embodiment, the elastic characteristic of the arc-shaped power receiving portion 312 is utilized to enable it to flexibly sleeve outside the conductive connecting member 23. In this way, the first arc-shaped contact surface 231 and the second arc-shaped contact surface 311 can be closely attached to each other, thereby realizing electrical connection and ensuring the effective transmission of current. At the same time, due to its elastic and arc-shaped characteristics, it can also adapt to a certain degree of mechanical deformation, improving the stability and reliability of the electrical connection, helping to reduce the contact resistance, improving the current transmission efficiency, reducing heat generation, and thus extending the service life of the power plug 100.

[0058] In some embodiments, a rib 313 is radially protruded on the surface of the arc-shaped power receiving portion 312 facing away from the conductive connecting member 23.

[0059] In this embodiment, the design of the rib 313 enhances the elasticity of the arc-shaped power receiving portion 312. When the conductive connecting member 23 slides relative to the power receiving member 31 driven by the rotating seat 21, the arc-shaped power receiving portion 312 can undergo a certain degree of elastic deformation under the action of an external force, thereby automatically adjusting its position to ensure close fitting with the conductive connecting member 23, reducing the problems of increased resistance and heat generation caused by poor contact. In addition, this design can also maintain the stability of the electrical connection between the power receiving member 31 and the conductive connecting member 23 through the elastic restoring force during long-term use, reducing the problem of poor contact caused by loosening or vibration.

[0060] In some embodiments, the power receiving member 31 further includes an outwardly protruding power receiving portion 314 radially protruding along the arc-shaped power receiving portion 312, and the outwardly protruding power receiving portion 314 is used for electrically connecting with the power cord 60.

[0061] In this embodiment, the provision of the outwardly protruding electrical connection portion 314 enhances the applicability and functionality of the electrical connection member 31, enabling it to adapt to different power connection requirements. Specifically, by providing the arc-shaped electrical connection portion 312 and the outwardly protruding electrical connection portion 314, it is allowed that the electrical connection member 31 can be electrically connected to the conductive connection member 23 not only through the arc-shaped electrical connection portion 312, but also directly connected to the power cord 60 through the outwardly protruding electrical connection portion 314, enabling the transmission of current between the pin 22 and the power cord 60.

[0062] In some embodiments, a notch 111 is provided in the accommodation cavity 11, and the outwardly protruding electrical connection portion 314 is provided at the notch 111.

[0063] In this embodiment, by placing the outwardly protruding electrical connection portion 314 at the notch 111, when the pin 22 rotates, even under the action of friction, it can be restricted by the notch 111 to prevent the electrical connection member 31 from moving, thereby preventing the occurrence of unstable or disconnected electrical connections caused by friction and ensuring the stability and reliability of the electrical connection.

[0064] Please refer to Figure 2 and Figure 5 , in some embodiments, the rotating base 21 includes a pin base 211 and an isolation base 212. The pin base 211 is connected to the isolation base 212. The pin 22 is provided on the pin base 211, and at least two conductive connection members 23 are sleeved outside the isolation base 212;

[0065] Among them, at least one outwardly protruding annular flange 213 is provided on the outer wall of the isolation base 212. The annular flange 213 is located between adjacent two conductive connection members 23 and is used to separate at least two conductive connection members 23.

[0066] In this embodiment, by providing the outwardly protruding annular flange 213, a physical isolation area can be formed between adjacent two conductive connection members 23 to avoid direct contact between the conductive connection members 23, thereby reducing the risk of short circuit or electrical failure and improving the overall safety and reliability of the power plug 100.

[0067] The pin base 211 and the isolation base 212 can be detachably connected, such as snap connection. This design not only facilitates the use of users, but also allows for the quick disassembly and assembly between the pin base 211 and the isolation base 212. When replacement or maintenance is required, the pin base 211 can be quickly detached from the isolation base 212, improving the convenience of use and the efficiency of maintenance.

[0068] Please refer to Figure 2 and Figure 3, in some embodiments, the rotating pin assembly 20 further includes a grounding connection member 24. The grounding connection member 24 is disposed in the receiving cavity 11. The grounding connection member 24 has a connection end 241 for electrically connecting with the pin 22 and a suspended end 242 located in the receiving cavity 11. The suspended end 242 is located at the rotation center of the rotating base 21;

[0069] The power plug 100 further includes a grounding conductive member 40. The grounding conductive member 40 is disposed in the receiving cavity 11. One end of the grounding conductive member 40 is in electrical contact with the suspended end 242, and the other end of the grounding conductive member 40 is electrically connected to the power cord 60.

[0070] In this embodiment, the suspended end 242 is located at the rotation center of the rotating base 21 and is in electrical contact with the grounding conductive member 40. This design ensures that the suspended end 242 remains in contact with the grounding conductive member 40 during the rotation of the rotating base 21, thereby maintaining a stable grounding state.

[0071] In this embodiment, the pin 22 further includes a grounding pin. The grounding pin is electrically connected to the grounding connection member 24, so that the power plug 100 has a grounding function, which plays a role in safety protection. By connecting to the ground, leakage of electricity is prevented, thereby protecting users from electric shock.

[0072] Among them, the neutral pin, the live pin, and the grounding pin can be designed to form different national specifications of arrangement shapes according to requirements. For example, it can be the arrangement shape of a US standard socket, or the arrangement shape of a UK standard socket, or the arrangement shape of other national standard sockets. Specific limitations are not made here.

[0073] Please refer to Figure 2 、 Figure 3 and Figure 6 , in some embodiments, the rotating base 21 has an inner cavity 214 and an avoidance hole 215 communicating with the inner cavity 214. The grounding connection member 24 is disposed in the inner cavity 214, the grounding conductive member 40 is disposed outside the rotating base 21, and a protrusion 41 is provided at one end of the grounding conductive member 40. The protrusion 41 extends into the inner cavity 214 through the avoidance hole 215 and is in electrical contact with the suspended end 242.

[0074] In this embodiment, the protrusion 41 of the grounding conductive member 40 extends into the inner cavity 214 through the avoidance hole 215 and is in electrical contact with the suspended end 242, ensuring the stable grounding of the power plug 100, and at the same time avoiding interference between the grounding conductive member 40 and the rotating pin assembly 20, resulting in the inability of the rotating pin assembly 20 to rotate.

[0075] In some embodiments, the power plug 100 further includes a fixing bracket 50. The fixing bracket 50 is disposed in the receiving cavity 11 and is used for installing the grounding conductive member 40; and / or,

[0076] The rotating pin assembly 20 further includes an elastic member 25, and the elastic member 25 is connected to the suspended end 242, so that the suspended end 242 is in electrical contact with the grounding conductive member 40 under the elastic action of the elastic member 25.

[0077] In this embodiment, the function of the fixing bracket 50 is to support and fix the grounding conductive member 40, prevent it from moving or falling off during use, so as to ensure that the current can be stably and safely transmitted through the grounding conductive member 40.

[0078] In this embodiment, through the elastic action of the elastic member 25, the suspended end 242 can maintain good electrical contact with the grounding conductive member 40, and the continuity of the electrical connection can be maintained even when the rotating base 21 rotates.

[0079] Please refer to Figure 7 , in some embodiments, each conductive connecting member 23 is provided with a connecting arm 232, and each connecting arm 232 is electrically connected to a pin 22; and / or,

[0080] Abutting ribs 112 protrude from the cavity wall of the accommodating cavity 11 facing away from the pins 22, and the abutting ribs 112 are used for abutting against the surface of the conductive connecting member 23 facing away from the pins 22.

[0081] In this embodiment, the conductive connecting member 23 forms an electrical path with the pin 22 through the connecting arm 232, thereby realizing the transmission of current. This design not only ensures the stability and reliability of the electrical connection, but also improves the safety and convenience of use of the device, and can effectively transmit the current from the power source to the power plug 100, while ensuring the stability and safety of the current, and avoiding electrical failures or safety hazards caused by poor contact or unstable connection.

[0082] In this embodiment, the abutting ribs 112 are used for abutting against the surface of the conductive connecting member 23 facing away from the pins 22, which can reduce the friction between the conductive connecting member 23 and the fixed seat 10 when rotating, help improve the rotation smoothness of the conductive connecting member 23, reduce the resistance generated by friction, and extend its service life.

[0083] Since the fixing bracket 50 is fixed to the fixed seat 10 only by a screw, one end of the fixing bracket 50 extending into the accommodating cavity 11 may be in a suspended state due to lack of sufficient support. In this case, the bracket is prone to shift under the influence of external forces.

[0084] To solve this problem, the abutting rib 112 in this embodiment is also used to limit the fixing bracket 50 to enhance the stability of the fixing bracket 50. Specifically, the function of the abutting rib 112 is to provide additional support and fixing force through its close contact with the fixing bracket 50, thereby preventing the fixing bracket 50 from shifting. This design not only improves the stability of the fixing bracket 50 but also enhances its safety in use, preventing displacement due to external forces or vibrations, etc., thus ensuring the overall stability and safety of the equipment and system.

[0085] The above embodiments of the present utility model are merely examples for clearly illustrating the present utility model and are not limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
