Description

Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to a plug and an electrical device. Background Art

[0002] The connector and pin of a general electronic product are called a plug. With the rapid development of electronic products, people have set the power pins of the plug to be rotatable and foldable to reduce the size of the plug itself, making it easier for people to carry and use in daily life.

[0003] Existing foldable plugs include pins and metal springs, which are electrically connected to the circuit board. This takes up space within the plug for wiring, making it difficult to route and connect the wires, which in turn poses a safety hazard. Furthermore, existing foldable plugs are only suitable for low-output currents and cannot meet high-output current requirements. When plugs with high-output currents are inserted into a socket, sparks can easily occur because the metal springs do not make full contact with the pins, reducing the plug's stability and safety during use.

[0038] like Figures 1-9 As shown, this embodiment provides a plug, which includes a base 1, an inserting member 3 and a connecting member 2. A receiving groove 11 is provided in the base 1, and the inserting member 3 includes a rotating shaft 32 and two lead members 33. The two lead members 33 are arranged at intervals on the rotating shaft 32. The rotating shaft 32 is rotatably connected to the base 1 and can rotate the two lead members 33 to extend or retract in the receiving groove 11. The connecting member 2 is provided on the base 1. The connecting member 2 is provided with a first connecting portion 21, a second connecting portion 22 and a third connecting portion 23. The second connecting portion 22 is electrically connected to the two lead members 33 in the extended state. A wire beam channel 12 is formed between the first connecting portion 21 and the inner wall of the receiving groove 11. The wire beam channel 12 is configured to pass a wire. The first connecting portion 21 is used to connect the wire core of the wire, and the third connecting portion 23 is kept in contact with the side wall of the lead member 33.

[0039] In this embodiment, the base 1 is provided with a receiving slot 11. The plug 3 includes a rotating shaft 32 and two lead-out members 33, spaced apart from the rotating shaft 32 and used to connect the live and neutral wires, respectively, to ensure normal use of the plug. The rotating shaft 32 is rotatably connected to the base 1 and can rotate the two lead-out members 33 to extend or retract within the receiving slot 11, allowing the plug 3 to be positioned between a folded position and a plugged position to meet the user's different plug usage requirements. The connector 2 includes a first connecting portion 21, a second connecting portion 22, and a third connecting portion 23. The second connecting portion 22 is electrically connected to the two lead-out members 33 in the extended position, ensuring the stability of the plug during power supply operation. A wire channel 12 for routing wires is formed between the first connecting portion 21 and the inner wall of the receiving slot 11, making wire routing and connection more convenient and improving the space utilization and safety of the plug's internal structure. The first connecting portion 21 is used to connect to the conductor core of the wire, ensuring electrical connection between the connector 2 and the conductor core, and meeting the requirements of high output current. The third connecting portion 23 maintains contact with the sidewall of the lead-out member 33, ensuring that the lead-out member 33 maintains electrical connection with the connector 2 during rotation, thereby improving the safety and stability of the plug and preventing sparks when the plug is inserted into a socket. Through the above arrangement, the plug of this embodiment can meet the demand for high output current while providing greater safety.

[0040] The specific structure of the plug is described below:

[0041] Specifically, if Figures 1-9 As shown, the plug-in component 3 includes a rotating shaft 32 and two lead-out pieces 33. The rotating shaft 32 is rotatably connected to the base 1, allowing the plug-in component 3 to flexibly rotate around the rotating shaft 32 on the base 1, thereby realizing the functions of folding, storing, and extending and unfolding the plug-in component 3. The two lead-out pieces 33 are spaced apart on the rotating shaft 32 and are used to connect the live wire and the neutral wire, respectively, thereby ensuring the normal use of the plug. In addition, a limit block is provided on the rotating shaft 32. When the rotating shaft 32 rotates relative to the base 1, the limit block abuts against the base 1, which can limit the rotation of the rotating shaft 32 and prevent the plug-in component 3 from rotating excessively.

[0042] More specifically, in this embodiment, lead member 33 is a metal plate that provides electrical contact with the socket. It is typically made of a high-toughness metal material such as iron or nickel-plated copper to ensure resistance to deformation during insertion and removal, ensuring durability. The shaft 32 is insulated from the lead member 33 to prevent short circuits. In other embodiments, lead member 33 may be a rod-shaped structure; as long as it can achieve the aforementioned functions, the specific structure of lead member 33 is not particularly limited.

[0043] Specifically, if Figure 4 and Figure 8 and Figure 9 As shown, each lead-out member 33 is provided with an abutment portion 31, and the connector 2 is provided with two. The two connectors 2 can abut against the two abutment portions 31 in a one-to-one correspondence, ensuring that when the plug-in member 3 is rotated to the plug-in position (i.e., the lead-out member 33 extends from the accommodating groove 11), the abutment portion 31 of each lead-out member 33 can accurately and reliably abut against the second connecting portion 22 on the corresponding connector 2, thereby ensuring the normal operation of the plug and reducing electrical faults caused by poor contact or connection errors. When the plug-in member 3 is rotated to the folded position (i.e., the lead-out member 33 is retracted into the accommodating groove 11), the abutment portion 31 and the second connecting portion 22 are spaced apart to prevent the abutment portion 31 from accidentally contacting and connecting with the second connecting portion 22.

[0044] More specifically, in this embodiment, the abutment portion 31 is a protrusion. When the plug-in member 3 is rotated from the folded position to the plug-in position, the protrusion gradually approaches the second connection portion 22 until the protrusion elastically abuts against the second connection portion 22, thereby achieving a stable and reliable electrical connection between the plug-in member 3 and the connector 2. When the lead-out member 33 is inserted into the socket, the current can smoothly pass through the lead-out member 33, the second connection portion 22, and the first connection portion 21 and then be transmitted to the wire and the corresponding electrical device, thereby ensuring the normal operation of the plug and the electrical device. In other embodiments, the abutment portion 31 is a columnar structure, that is, as long as it can achieve the above-mentioned functional effects, the specific structure of the abutment portion 31 is not further limited.

[0045] Specifically, if Figure 4-Figure 9 As shown, the third connecting portion 23 includes an extension 232 and a clamping plate 231. The extension 232 extends axially along the rotating shaft 32, allowing the third connecting portion 23 to extend and maintain contact with the side walls of the lead-out member 33. Clamping plates 231 extend from either side of the extension 232 toward the rotating shaft 32. The two clamping plates 231 resiliently clamp the side walls of the lead-out member 33, ensuring a stable electrical connection between the lead-out member 33 and the connector 2 during rotation of the insert 3 relative to the base 1. This effectively prevents sparks caused by poor contact and improves the safety and stability of the plug.

[0046] Specifically, if Figure 4-Figure 9 As shown, the side wall of the lead-out piece 33 is provided with an extension end 331, and the extension end 331 extends along the axial direction of the rotating shaft 32, ensuring that when the plug-in piece 3 rotates around the axis of the rotating shaft 32, the lead-out piece 33 can always maintain a stable connection state with the third connecting portion 23, thereby enhancing the stability of the electrical connection. The two clamping plates 231 are provided with arc-shaped contact portions 2311 that match the shape of the extension ends 331, so that the clamping plates 231 can fit more closely to the surface of the extension ends 331, thereby ensuring the firmness of the electrical connection. When the plug-in piece 3 rotates or is subjected to other external forces, the electrical connection can also be kept stable. Such a setting not only improves the safety of the plug, but also enables the plug to maintain a good contact state during long-term use.

[0047] More specifically, in this embodiment, the extended end 331 is a guide post, which is arranged on the side wall of the lead-out piece 33 and extends along the axial direction of the rotating shaft 32. The guide post is clamped between the two arc-shaped contact portions 2311 to ensure that the connector 2 can always be electrically connected to the lead-out piece 33 through the guide post, thereby improving the safety and stability of the plug and avoiding sparks when the plug is inserted into the socket.

[0048] Specifically, if Figure 4-Figure 9 As shown, the first connecting portion 21 includes a first bent section 211 and a second bent section 212, which are connected in sequence. The first bent section 211 extends along a first direction, and the second bent section 212 extends along a second direction. The first and second directions are arranged at an angle. This arrangement allows the second bent section 212 to easily connect to the conductor core of the wire, thereby ensuring the stability and reliability of the electrical connection. Riveting arms 2121 are provided on both sides of the second bent section 212. The riveting arms 2121 are used to rivet the conductor core of the wire, thereby ensuring the stability of the electrical connection between the first connecting portion 21 and the conductor core, meeting the requirements of high output current of the plug.

[0049] Specifically, if Figure 4 and Figure 5As shown, two limiting plates 24 are spaced apart on the connector 2, and a raised portion 13 is provided on the base 1. The raised portion 13 is assembled between the two limiting plates 24 so that during assembly, the raised portion 13 can be smoothly inserted along the space between the two limiting plates 24, ensuring proper assembly between the connector 2 and the base 1. In this embodiment, the raised portion 13 is a block-shaped or rod-shaped protrusion, and the specific structure of the raised portion 13 is not further limited herein.

[0050] Specifically, if Figure 4 and Figure 5 As shown, the connector 2 is provided with a positioning hole 25, and the base 1 is provided with a positioning member 14. The positioning member 14 is inserted into the positioning hole 25. The cooperation between the positioning hole 25 and the positioning member 14 ensures that the connector 2 and the base 1 are precisely aligned during assembly, thereby facilitating assembly operations and improving efficiency. The positioning member 14 in this embodiment is a positioning rod or a positioning block, and the specific structure of the positioning member 14 is not further limited herein.

[0051] Specifically, if Figure 2-Figure 9 As shown, the plug also includes a pressing plate 4, which is connected to the base 1. The connecting member 2 is provided with a connecting groove 26. The pressing plate 4 is clamped in the connecting groove 26, so that the pressing plate 4, the connecting member 2 and the base 1 form a stable overall structure, and can protect the electrical components between the pressing plate 4 and the base 1, thereby improving the safety and reliability of the plug.

[0052] More specifically, if Figure 8 As shown, one end of the connecting member 2 is folded and extended toward one side of the connecting member 2 to form a second connecting portion 22, and the other end of the connecting member 2 is folded toward the other side of the connecting member 2 to form a connecting groove 26. The folding setting of the connecting member 2 simplifies the processing process, reduces production costs and processing difficulty, and improves production efficiency.

[0053] Specifically, if Figure 2-Figure 9 As shown, one of the connecting member 2 and the pressure plate 4 is provided with a snap-in hole 27, and the other is provided with a protrusion 41 snapped into the snap-in hole 27. The cooperation between the snap-in hole 27 and the protrusion 41 can not only simplify the assembly process, but also ensure a firm connection between the connecting member 2 and the pressure plate 4, preventing loosening or falling off due to vibration or impact during use.

[0054] More specifically, in this embodiment, each connector 2 is provided with a snap-fit ​​hole 27, and a protrusion 41 is provided on the pressure plate 4. During assembly, the pressure plate 4 extends into the connection slot 26 and engages with the snap-fit ​​hole 27 via the protrusion 41, thereby achieving a secure connection between the pressure plate 4 and the connector 2. In other embodiments, the snap-fit ​​hole 27 is provided on the pressure plate 4, and the protrusion 41 is provided on the connector 2. The specific locations of the snap-fit ​​hole 27 and the protrusion 41 are not particularly limited, as long as they can achieve the aforementioned functions.

[0055] Specifically, if Figures 1-9 As shown, the connector 2 is made of phosphor bronze. Since phosphor bronze has a high hardness, the connector 2 made of phosphor bronze can withstand greater stress and load and is not prone to deformation or breakage.

[0056] This embodiment also provides an electrical device comprising a wire and a plug. The wire passes through a wiring harness channel 12 and is connected to a first connection portion 21. This device can meet the demand for high output current and provides enhanced safety. The electrical device includes, but is not limited to, a water dispenser, a laptop, a washing machine, an electric fan, and an air conditioner. The specific structure and purpose of the electrical device are not specifically defined herein.

[0057] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
