Rotatable plug

Abstract

This utility model discloses a rotatable plug, including a base, a rotating cover, and multiple pins. The bottom wall has annular partitions; these partitions divide the space enclosed by the side walls into multiple rotating cavities. The rotating cover is rotatably connected to the top of the base and has multiple sockets. Multiple pins are fixed to their corresponding sockets, and each pin is electrically connected to a corresponding electrode plate via a contact piece. Each contact piece is rotatably positioned within its corresponding rotating cavity. This utility model, by using annular partitions within the base to divide the side wall space into multiple independent rotating cavities, ensures physical isolation of the circuitry of each pin. Thus, when the rotating cover rotates the pins, the contact piece rotates synchronously around its axis within the rotating cavity, maintaining a 360° circumferential conductive path through its annular sliding contact surface with the base electrode plate. The plug can be rotated to any target angle before insertion, completely eliminating cable tangling problems and further improving power supply stability.

Description

Technical Field

[0001] This utility model relates to the field of plug technology, and in particular to a rotatable plug. Background Technology

[0002] Traditional plugs, with their fixed pin orientation, present significant limitations in use. When the power socket's installation direction is restricted (e.g., non-standard orientation of wall sockets) or when equipment cables require multiple bends, fixed plugs often lead to difficulties in insertion, cable twisting and tangling, and even wear and tear on the pins or socket due to repeated insertion and removal adjustments. This is especially true for multi-prong plugs (such as three-prong plugs), which require strict matching to the socket angle, resulting in a poor user experience and safety hazards. While existing rotatable plugs attempt to address the orientation issue, they often employ a single rotating structure, making internal conductive components prone to misalignment and poor contact during rotation, or causing arcing due to electrode friction during rotation. This makes it difficult to simultaneously meet the dual requirements of free rotation at multiple angles and continuous, stable power supply. Therefore, maintaining a stable electrical connection between the pins and the power electrodes at any rotation angle is a pressing problem that needs to be solved. Utility Model Content

[0017] The rotatable plug provided by this utility model divides the side wall space into multiple independent rotating cavities by setting an annular partition inside the base, ensuring physical isolation of the circuits of each pin. Thus, when the rotating cover drives the pins to rotate, the contact plate rotates synchronously around the axis within the rotating cavity, maintaining a 360° circumferential conductive path through its annular sliding contact surface with the base electrode plate. Therefore, it has the following technical effects:

The annular contact surface design ensures that the electrode plate and the electrode plate always maintain surface contact, eliminating the generation of electric arc during rotation.

[0020] (3) Structural reliability and extended service life: The independent rotating cavities separated by partitions prevent short circuits between adjacent circuits, while reducing the number of times the pins are plugged in and unplugged (only rotation is needed to adjust the direction), significantly reducing interface wear.

It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0035] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0036] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0037] In this embodiment of the invention, a rotatable plug 100 is provided for insertion into a socket to enable current input to an external power source, thereby providing power to electronic devices. Different plugs, such as US, EU, UK, Japanese, Chinese, and Australian plugs, can be provided simultaneously to enhance the product's applicability.

[0038] like Figures 1-6 As shown, the rotatable plug 100 includes: a base 10, a rotating cover 20, and multiple prongs.

[0039] The base 10 is fixed inside the outer shell 200 of the plug and connected to the main board 300, so that the external power supply can be converted by the main board 300 to obtain and output current suitable for electronic devices.

[0040] Specifically, the base 10 includes a circular bottom wall 11 and side walls 12 extending vertically from the edge of the bottom wall 11. The bottom wall 11 and the side walls 12 together enclose a cylindrical space. The bottom wall 11 is provided with annular partitions (131, 132). The number of partitions can be one (for two-prong plugs) or two (for three-prong plugs). The partitions divide the space enclosed by the side walls into multiple rotating cavities.

[0041] In this embodiment, combined with Figure 6 As shown, the partition includes a first partition 131 and a second partition 132, both annular and concentrically arranged with the bottom wall 11. That is, the first partition 131, the second partition 132, and the side wall 12 form a concentric circle structure, with the first partition 131 located at the innermost edge of the concentric circle and the side wall 12 at the outermost edge. Correspondingly, the plurality of rotating cavities (101, 102, 103) include a first rotating cavity 101 formed by the first partition 131, a second rotating cavity 102 formed by the first partition 131 and the second partition 132, and a third rotating cavity 103 formed by the second partition 132 and the side wall 12. Therefore, all three rotating cavities are annular and concentrically arranged.

[0042] Combination Figures 2-4 As shown, the rotating cover 20 is rotatably connected to the top of the base 10 to enclose the space enclosed by the base 10. The rotating cover 20 has multiple insertion holes (21, 22) at preset positions. Multiple pins (31, 32) are inserted and fixed into the corresponding insertion holes.

[0043] In this embodiment, the plurality of pins (31, 32) include a cylindrical first pin 31 and two plate-shaped second pins 32, thereby forming a three-prong plug. Correspondingly, the plurality of sockets (21, 22) include a first socket 21 for the first pin 31 to pass through and two second sockets 22 for the second pins 32 to pass through.

[0044] Specifically, in combination Figure 5 As shown, the inner wall of the first insertion hole 21 is provided with a limiting protrusion 211. A first limiting groove 311, adapted to the limiting protrusion 211, is provided on the side of the first insertion pin 31 near the base 10. The limiting protrusion 211 engages with the first limiting groove 311 to fix the first insertion pin 31 onto the rotating cover 20, thus preventing the first insertion pin 31 from detaching from the first insertion hole 21. Since the second insertion pin 32 is plate-shaped, the second insertion hole 22 is a strip-shaped hole, and a fixing rod 221 is provided along the width direction in the middle of the inner wall of the second insertion hole 22. A limiting block 222 is provided at one or both ends of the inner wall of the second insertion hole 22 along the length direction. Here, there are two limiting blocks 222, spaced apart on both sides of the fixing rod 221. A fixing hole 321 and a second limiting groove 322 adapted to the limiting block 222 are provided on the side of the second insertion pin 32 near the base 10. The fixing rod 221 passes through the fixing hole 321, and the limiting block 222 is inserted into the corresponding second limiting groove 322 to fix the second pin 32 on the rotating cover 20, so that the second pin 32 will not come out of the corresponding second socket 22.

[0045] Each pin is electrically connected to its corresponding electrode via a contact piece. Each contact piece is rotatably mounted in its corresponding rotating cavity so that the electrical connection between the pin and the corresponding contact piece can be maintained when the rotating cover 20 rotates synchronously with the pin.

[0046] Specifically, the plurality of contact pieces (41, 42) includes a first contact piece 41 and two second contact pieces 42. The first contact piece 41 is rotatably disposed in the first rotating cavity 101 and fixedly connected to the first pin 31. Therefore, when the first pin 31 rotates with the rotating cover 20, the first contact piece 41 will rotate synchronously within the first rotating cavity 101. The two second contact pieces 42 are rotatably disposed in the second rotating cavity 102 and the third rotating cavity 103 respectively, and fixedly connected to the two second pins 32 respectively. Therefore, when the second pins 32 rotate with the rotating cover 20, the second contact pieces 42 will rotate synchronously within the second rotating cavity 102 and the third rotating cavity 103 respectively.

[0047] Furthermore, a first conductive sheet 1011 is attached to the bottom of the first rotating cavity 101, and a first through hole 1012 is provided on the edge. One end of the first plug-in piece 1013 is electrically connected to the first conductive sheet 1011, and the other end passes through the first through hole 1012 and extends out of the bottom wall 11 on the side away from the first pin 31, so that the first plug-in piece 1013 leads the first conductive sheet 1011 out to the bottom of the base 10, so as to facilitate connection with the motherboard 300 through the corresponding electrode piece.

[0048] A second conductive sheet 1021 is attached to the bottom of the second rotating cavity 102, and a second through hole 1022 is provided on the edge. One end of the second plug-in piece 1023 is electrically connected to the second conductive sheet 1021, and the other end passes through the second through hole 1022 and extends out of the bottom wall 11 on the side away from the second pin 32, so that the second plug-in piece 1023 leads the second conductive sheet 1021 out to the bottom of the base 10, so as to facilitate connection with the main board 300 through the corresponding electrode piece.

[0049] A third conductive sheet 1031 is attached to the bottom of the third rotating cavity 103, and a third through hole 1032 is provided on the edge. One end of the third plug-in piece 1033 is electrically connected to the third conductive sheet 1031, and the other end passes through the third through hole 1032 and extends out of the bottom wall 11 on the side away from the second pin 32, so that the third plug-in piece 1033 leads the third conductive sheet 1031 out to the bottom of the base 10, so as to connect with the main board 300 through the corresponding electrode piece.

[0050] The electrode plates (51, 52, 53) include a first electrode plate 51, a second electrode plate 52, and a third electrode plate 53. The first electrode plate 51 has a first snap-fit ​​hole 511 that snaps into the first plug-in piece 1013, the second electrode plate 52 has a second snap-fit ​​hole 521 that snaps into the second plug-in piece 1023, and the third electrode plate 53 has a third snap-fit ​​hole 531 that snaps into the third plug-in piece 1033, thereby forming an electrical connection.

[0051] In this embodiment, the first contact piece 41 includes a first connecting piece 411 and a first sliding piece 412 and a first fixing piece 413 respectively connected to both ends of the first connecting piece 411. The first pin 31 is connected to the first fixing piece 413, and the first sliding piece 412 is slidably connected to the first conductive piece 1011, thereby forming an electrical connection contact surface between the first sliding piece 412 and the first conductive piece 1011. Due to the presence of the first connecting piece 411, the first fixing piece 413 has a certain elasticity to accommodate the pressing action of the first pin 31.

[0052] The second contact piece 42 includes a second connecting piece 421 and a second sliding piece 422 and a second fixing piece 423 respectively connected to both ends of the second connecting piece 421. Two second pins 32 are respectively connected to the two second fixing pieces 423. The two second sliding pieces 422 are slidably connected to the second conductive piece 1021 and the third conductive piece 1031, respectively, thereby forming electrical connection contact surfaces with the second conductive piece 1021 and the third conductive piece 1031. Due to the presence of the second connecting piece 421, the second fixing piece 423 has a certain elasticity to accommodate the pressing action of the second pins 32.

[0053] The first fixing piece 413 has a first limiting hole 4131, and the second fixing piece 423 has a second limiting hole 4231. A first driving block 23 and two second driving blocks 24 are vertically positioned on the side of the rotating cover 20 near the base 10. The first driving block 23 is inserted and engaged with the first limiting hole 4131, and the two second driving blocks 24 are respectively inserted and engaged with their corresponding second limiting holes 4231, so that when the rotating cover 20 rotates, it can synchronously drive the first contact piece 41 and the second contact piece 42 to rotate. That is, when the rotating cover 20 rotates, it can drive the three pins to rotate synchronously, and the three driving blocks can also drive the three fixing pieces to rotate on their corresponding conductive pieces, achieving 360° circumferential conductive path maintenance.

[0054] Furthermore, in some embodiments, combined with Figures 3-5 As shown, a first receiving groove 251 is formed on the side wall of the rotating cover 20, with the opening of the first receiving groove 251 facing the side wall 12 of the base 10. A positioning block 26 is provided in the first receiving groove 251. The positioning block 26 has a second receiving groove 252 with its opening facing the rotating cover 20, and a positioning cone 261 is provided on the side away from the rotating cover 20. A compression spring 27 is provided between the bottom of the first receiving groove 251 and the bottom of the second receiving groove 252. When the compression spring 27 is compressed, it tends to push the positioning block 26 outward. Correspondingly, a number of positioning grooves 121 are formed by extending outward from the preset position of the side wall 12, for example, three positioning grooves 121 evenly distributed along the circumference.

[0055] The compression spring 27 drives the positioning block 26 so that the positioning cone 261 extends into any positioning groove 121, playing a certain positioning and limiting role, and preventing the rotating cover 20 from easily rotating relative to the side wall 12 of the base 10. When it is necessary to rotate the pins (31, 32) by an angle, the user rotates with a little force to compress the compression spring 27, causing the positioning cone 261 to disengage from the positioning groove 121 until the positioning cone 261 is aligned with the next positioning groove 121. At this time, under the push of the compression spring 27, the positioning cone 261 is engaged in the positioning groove 121 to maintain the rotation angle of the rotating cover 20 within a certain force range. Furthermore, the positioning groove 121 has a slope or arc transition on both sides along the rotation direction of the positioning cone 261 to reduce the difficulty of rotating the rotating cover 20, making the rotation of the rotating cover 20 smoother.

[0056] It should be noted that the aforementioned contact plate, conductive plate, electrode plate, and pin are all made of conductive material, while the partition and side wall 12 are made of insulating material.

[0057] In summary, the rotatable plug 1100 provided by this utility model, by providing an annular partition (131, 132) inside the base 10, divides the space of the side wall 12 into multiple independent rotating cavities (101, 102, 103), ensuring that the circuits of each pin (31, 32) are physically isolated. Thus, when the rotating cover 20 drives the pins to rotate, the contact plates (41, 42) rotate synchronously around the axis within the rotating cavity. Through their annular sliding contact surface with the electrode plates (51, 52) of the base 10, a 360° circumferential conductive path is maintained. Therefore, it has the following technical effects:

[0058] (1) Full-angle free adaptation: The plug can be rotated to the target angle before plugging in (such as rotating 90° to avoid obstacles), completely eliminating the problem of cable tangling, especially suitable for narrow spaces or unconventional sockets;

[0059] (2) Improved power supply stability: The electrode plate rotates in a closed rotating cavity to avoid external interference. The annular contact surface design ensures that the electrode plate and the electrode plate always maintain surface contact, eliminating the generation of electric arc during rotation.

[0060] (3) Structural reliability and extended service life: The independent rotating cavities separated by partitions prevent short circuits between adjacent circuits, while reducing the number of times the pins are plugged in and unplugged (only rotation is needed to adjust the direction), significantly reducing interface wear.

[0061] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
