TECHNICAL FIELD

[0001] The present disclosure relates to a technical field of plugs, and in particular to a plug with linked flipping pins. BACKGROUND

[0002] A rotating plug is a type of plug that has swiveling pins, hence its name. When in use, the swiveling pins of the rotating plug is rotated from a folded state to a vertical state, and then the swiveling pins are plugged into a power outlet. When not in use, the swiveling pins are rotated back from the vertical state to the folded state, realizing convenient storage of the rotating plug.

[0003] Currently, the swiveling pins of the rotating plug are linked to realize simultaneous deployment or storage. However, linkage between the swiveling pins is not optimal, leading to poor synchronization during rotation. Additionally, since the swiveling pins are linked, rotation stability thereof is compromised, resulting in a subpar user experience. SUMMARY

[0004] The present disclosure provides a plug with linked flipping pins to solve technical problems that linkage between conventional swiveling pins is not optimal, synchronization of the conventional swiveling pins during rotation is poor, rotation stability of the conventional swiveling pins is compromised, and a user experience is poor due to the linkage between the conventional swiveling pins.

[0005] The present disclosure provides the plug with linked flipping pins. The plug comprises a housing, two first rotating pins, a second rotating pin, a first linkage piece, and a second linkage piece.

[0006] One end of the second rotating pin and one end of each of the two first rotating pins are rotatably mounted in the housing. The first linkage piece and the second linkage piece are movably mounted in the housing.

[0007] The first linkage piece is fixedly connected to the two first rotating pins, and the second linkage piece is rotatably connected to the second rotating pin and the first linkage piece, so that the second rotating pin and the two first rotating pins are linked by the first linkage piece and the second linkage piece, and the two first rotating pins are linked by the first linkage piece.

[0008] Optionally, a rotating center of the second linkage piece and a rotating center of the first linkage piece are eccentrically disposed with rotating centers, on the housing, of the two first rotating pins.

[0009] The rotating center of the second linkage piece and a rotating center of the second rotating pin is eccentrically disposed with a rotating center, on the housing, of the second rotating pin.

[0010] Optionally, the first linkage piece comprises a first connecting portion and two first connecting arms. The two first connecting arms are respectively connected to two ends of the first connecting portion at an included angle. The two first rotating pins are respectively rotatably connected to the two first connecting arms. One end of the second linkage piece is rotatably connected to the two first connecting arms.

[0011] Optionally, the second linkage piece comprises two second connecting arms. First ends of the two second connecting arms are respectively rotatably connected to two sides of the second rotating pin, second ends of the two second connecting arms are respectively rotatably connected to the two first connecting arms.

[0012] Optionally, the second linkage piece further comprises a second connecting portion, and the second ends of the two second connecting arms are connected through the second connecting portion.

[0013] Optionally, the second ends of the two second connecting arms and the second connecting portion are disposed between the two first connecting arms, and a rotating gap is defined between the first connecting portion and the second connecting portion.

[0014] Optionally, two receiving grooves are defined in the housing, and a snapping convex plate is disposed between the two receiving grooves in the housing.

[0015] The two second connecting arms are respectively accommodated in the two receiving grooves, and the second connecting portion is snapped on the snapping convex plate.

[0016] Optionally, the plug further comprises an inner pressing cover. The inner pressing cover is mounted in the housing. The inner pressing cover and the housing jointly limit positions of the second rotating pin and the two first rotating pins.

[0017] Optionally, two first positioning grooves are defined on at least one of a rotating end of the second rotating pin and rotating ends of the two first rotating pin. A positioning structure is disposed on one side of the inner pressing cover facing the second rotating pin and the two first rotating pins, and the positioning structure is corresponding to the two first positioning grooves.

[0018] When the second rotating pin and the two first rotating pins are rotated to a use state, the positioning structure is clamped into a first one of the two first positioning grooves. When the second rotating pin and the two first rotating pins are rotated to a storage state, the positioning structure is clamped into a second one of the two first positioning grooves.

[0019] Optionally, two first accommodating grooves and a second accommodating groove are defined in a side surface of the housing. The two first rotating pins are respectively rotatably mounted in the two first accommodating grooves. The second rotating pin is rotatably mounted in the second accommodating groove.

[0020] Compared with the prior art, in the present disclosure, the plug with linked flipping pins realizes simultaneous linkage of the second rotating pin and the two first rotating pins by providing the first linkage piece and the second linkage piece. In this way, when folding or unfolding three pins (i.e., the second rotating pin and the two first rotating pins), only one of the second rotating pin and the two first rotating pins needs to be rotated to fold or open the second rotating pin and the two first rotating pins synchronously.

DETAILED DESCRIPTION

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other. In conjunction with the accompanying drawings, preferred embodiments of the present disclosure are described in detail.

[0034] Embodiments of the present disclosure provide a plug with linked flipping pins. As shown in FIGS. 1-4, the plug comprises a housing 1, two first rotating pins 5, a second rotating pin 2, a first linkage piece 3, and a second linkage piece 4. One end of the second rotating pin 2 and one end of each of the two first rotating pins 5 are rotatably mounted in the housing 1. The first linkage piece 3 and the second linkage piece 4 are movably mounted in the housing 1.

[0035] The first linkage piece 3 is fixedly connected to the two first rotating pins 5, and the second linkage piece 4 is rotatably connected to the second rotating pin 2 and the first linkage piece 3, so that the second rotating pin 2 and the two first rotating pins 5 are linked by the first linkage piece 3 and the second linkage piece 4, and the two first rotating pins 5 are linked by the first linkage piece 3.

[0036] In the present disclosure, the plug with linked flipping pins realizes simultaneous linkage of the second rotating pin 2 and the two first rotating pins 5 by providing the first linkage piece 3 and the second linkage piece 4. In this way, when folding or unfolding the three pins (i.e., the second rotating pin 2 and the two first rotating pins 5), only one of the second rotating pin 2 and the two first rotating pins 5 needs to be rotated to fold or open the second rotating pin 2 and the two first rotating pins 5 synchronously. More importantly, the first linkage piece 3 of the present disclosure directly connects the two first rotating pins 5 while being rotatably connected to the second linkage piece 4, so that the two first rotating pins 5 are fixedly connected through the first linkage piece 3. In this way, it is ensured that a driving force is directly transmitted between the two first rotating pins 5 through the first linkage piece 3, so that the two first rotating pins 5 are smoothly synchronously rotated. The first linkage piece 3 is linked to the second linkage piece 4 to realize the linkage of the three pins, so that a linkage effect of the second rotating pin 2 and the two first rotating pins 5 is good, the consistency of a synchronous rotation of the three pins is good, an overall rotation of the three pins is stable, and a rotation experience is good.

[0037] Specifically, the first linkage piece 3 is integrally formed with the two first rotating pins 5, or the first linkage piece 3 and the two first rotating pins 5 are fixedly connected by fixing pieces or fixing structures such as screws and fasteners.

[0038] Specifically, a rotating center of the second linkage piece 4 and a rotating center of the first linkage piece 3 are eccentrically disposed with rotating centers, on the housing 1, of the two first rotating pins 5. Similarly, the rotating center of the second linkage piece 4 and a rotating center of the second rotating pin 2 is eccentrically disposed with a rotating center, on the housing 1, of the second rotating pin 2. In the embodiment, the rotating center of the second linkage piece 4 and the rotating center of the second rotating pin 2 are eccentrically disposed with respect to the rotating center of the second rotating pin 2 on the housing 1, and the second rotating pin 2 is connected to the housing 1, so the rotating center of the second rotating pin 2 on the housing 1 is not shift. In this way, when the second rotating pin 2 is rotated, the second linkage piece 4 is pushed to move forward and backward by eccentric arrangements of the the rotating center of the second linkage piece 4 and the rotating center of the second rotating pin 2. The rotating center of the second linkage piece 4 and the rotating center of the first linkage piece 3 are eccentrically disposed with respect to the rotating centers, on the housing 1, of the two first rotating pins 5, and the two first rotating pins 5 are connected to the housing 1, so the rotating centers, on the housing 1, of the two first rotating pins 5 do not shift. When the second linkage piece 4 moves forward and backward, the second linkage piece 4 drives the first linkage piece 3 to flip through eccentrically arrangement of the rotating center of the second linkage piece 4 and the rotating center of the first linkage piece 3,, thereby driving the two first rotating pins 5 and the second rotating pin 2 to synchronously flip and realizing synchronous storage or unfolding of the second rotating pin 2 and the two first rotating pins 5.

[0039] Of course, in actual use, the user is able to move any one of the second rotating pin 2 and the two first rotating pins 5 to realize the synchronous storage or unfolding of the second rotating pin 2 and the two first rotating pins 5.

[0040] Specifically, the first linkage piece 3 comprises a first connecting portion 31 and two first connecting arms 32. The two first connecting arms 32 are respectively connected to two ends of the first connecting portion 31 at an included angle. The two first rotating pins 5 are respectively rotatably connected to the two first connecting arms 32. One end of the second linkage piece 4 is rotatably connected to the two first connecting arms 32. By providing the first connecting portion 31 and the two first connecting arms 32, the linkage between the two first rotating pins 5 is realized through the first linkage piece 3. When the plug is folded or unfolded, the second linkage piece 4 drives the first linkage piece 3 to rotate, so as to realize storage or unfolding of the two first rotating pins 5. Specifically, a rotating center of one end, rotatably connected to the two first connecting arms 32, of the second linkage piece 4 is eccentrically disposed between the rotating centers of the two first rotating pins 5 on the housing 1, so that the second linkage piece 4 drives the first linkage piece 3 to flip, and the two first rotating pins 5 are driven to be folded or unfolded. The two first connecting arms 32 are vertically connected to two ends of the first connecting portion 31, which improves convenience of connections between second connecting arms 41 and the first connecting arms 32 and reduces driving difficulty of the second connecting arms 41 on the first connecting arms 32, so that the second connecting arms 41 drive the first connecting arms 32 stably, smoothly and effortlessly.

[0041] Furthermore, the second linkage piece 4 comprises two second connecting arms 41. First ends of the two second connecting arms 41 are respectively rotatably connected to two sides of the second rotating pin 2, and second ends of the two second connecting arms 41 are respectively rotatably connected to the two first connecting arms 32. The second linkage 4 comprises the two second connecting arms 41, the two second connecting arms 41 are rotatably connected to the two sides of the second rotating pin 2 and are respectively rotatably connected to the two first connecting arms 32, so as to drive the second rotating pin 2 and the first linkage piece 3, which effectively improves rotation stability of the second rotating pin 2 and the first linkage piece 3. Therefore, rotation force of the second rotating pin 2 and the first linkage piece 3 is balanced, and the rotation of the second rotating pin 2 and the first linkage piece 3 is smooth, stable and labor-saving. Specifically, the rotating centers, rotatably connected to the two sides of the second rotating pin 2, of the first ends of the two second connecting arms 41 are eccentrically disposed with respect to the rotating center, on the housing 1, of the second rotating pin 2. The rotating centers, rotatably connected to the two first connecting arms 32, of second ends of the two second connecting arms 41 are eccentrically disposed with respect to the rotating center of the first rotating pin 5 on the housing 1. In this way, when the three pins are rotated to be folded or unfolded, the second linkage piece 4 moves forward and backward under driving of any one of the three pins, thereby driving the first linkage piece 3 to flip. The second rotating pin 2 and the two first rotating pins 5 are synchronously folded or unfolded.

[0042] The second linkage piece 4 further comprises a second connecting portion 42. The second ends of the two second connecting arms 41 are connected through the second connecting portion 42. Because the two second connecting arms 41 need to drive the first linkage piece 3 and the two first rotating pins 5 to rotate, and the rotating centers, rotatably connected to the two first connecting arms 31, of the second ends of the two second connecting arms 41 are eccentrically disposed with respect to the rotating center of the two first rotating pins 5 on the housing 1, during the rotation of the three pins, the force on the second ends of the two second connecting arms 41 rotatably connected to the two first connecting arms 32 is relatively large, and structural strength and stability of the second ends of the two second connecting arms 41 are required to be relatively high. Therefore, in the embodiment, the second ends, rotatably connected to the two first connecting arms 32, of the two second connecting arms 41 are connected through the second connecting portion 42. The second connecting portion 42 strengthens the structural strength and stability of the second ends of the two second connecting arms 41, improves structural stability of the second ends of the two second connecting arms 41, ensures that the second linkage piece 4 stably drives the first linkage piece 3 and the two first rotating pins 5, and avoids the two first connecting arms 32 from being damaged by excessive force or having poor connection.

[0043] Furthermore, the second ends of the two second connecting arms 41 and the second connecting portion 42 are disposed between the two first connecting arms 32, which improves assembly compactness between the first linkage piece 3 and the second linkage piece 4 and is conducive to miniaturization of the plug. A rotating gap is defined between the first connecting portion 31 and the second connecting portion 42, which ensures normal rotation of the first linkage piece 3, so the first linkage piece 3 is not affected by interference of the second connecting portion 42. During the process of folding or unfolding the three pins, the first linkage piece 3 is flipped above the second connecting portion 42, and the first connecting portion 31 passes over the second connecting portion 42.

[0044] Optionally, two receiving grooves 111 are defined in the housing 1, and a snapping convex plate 112 is disposed between the two receiving grooves 111 in the housing 1. The two second connecting arms 41 are respectively accommodated in the two receiving grooves 111, and the second connecting portion 42 is snapped on the snapping convex plate. The two accommodating grooves 111 limit positions of the two second connecting arms 41 and are for mounting the two second connecting arms 41, thereby improving mounting stability and movement stability of the second linkage piece 4. The second connecting portion 42 is snapped on the snapping convex plate 112, which further improves the mounting stability and the movement stability of the second linkage piece 4.

[0045] Furthermore, a first groove 112a corresponding to the first connecting portion 31 is defined in the snapping convex plate 112. When the two first rotating pins 5 are in use, the first connecting portion 31 is accommodated in the first groove 112a.

[0046] As shown in FIGS. 5 and 6, the plug further comprises an inner pressing cover 6. The inner pressing cover 6 is mounted in the housing 1. The inner pressing cover 6 and the housing 1 jointly limit positions of the second rotating pin 2 and the two first rotating pins 5. In the embodiment, the inner pressing cover 6 cooperates with the housing I to realize the rotatable mounting of the second rotating pin 2 and the two first rotating pins 5. The second rotating pin 2 and the two first rotating pins 5 comprise rotating shafts, and the inner pressing cover 6 and the housing 1 are comprise mounting grooves. The rotating shafts of the second rotating pin 2 and the two first rotating pins 5 are respectively mounted in the mounting grooves and are pressed by the inner pressing cover 6, so that the second rotating pin 2 and the two first rotating pins 5 are mounted and fixed.

[0047] Two first positioning grooves 21 are defined on at least one of a rotating end of the second rotating pin 2 and rotating ends 51 of the two first rotating pins 5. A positioning structure 61 is disposed on one side of the inner pressing cover 6 facing the second rotating pin 2 and the two first rotating pins 5, and the positioning structure 61 is corresponding to the two first positioning grooves 21.

[0048] When the second rotating pin 2 and the two first rotating pins 5 are rotated to a use state, the positioning structure 61 is clamped into a first one of the two first positioning grooves 21. When the second rotating pin 2 and the two first rotating pins 5 are rotated to a storage state, the positioning structure 61 is clamped into a second one of the two first positioning grooves 21.

[0049] The first one of the first positioning groove 21 cooperates with the positioning structure 61 to position the second rotating pin 2 and the two first rotating pins 5 in the use state. The positioning structure 61 is a protrusion.

[0050] Optionally, two first accommodating grooves 114 and a second accommodating groove 113 are defined in a side surface of the housing 1. The two first rotating pins 5 are respectively rotatably mounted in the two first accommodating grooves 114. The second rotating pin is rotatably mounted in the second accommodating groove 113. The second accommodating groove 113 and the two first accommodating grooves 114 facilitate the storage of the second rotating pin 2 and the two first rotating pins 5.

[0051] As shown in FIGS. 5-9, the plug with linked flipping pins further comprises conductive sheets 7. Each of the conductive sheets 7 comprises a mounting portion 71, a first bending portion 72, a positioning portion 73, and a second bending portion 74. Each of the conductive sheets 7 is mounted in the plug through each mounting portion 71. A first end of each first bending portion 72 is connected to one end of a corresponding mounting portion 71, a first end of each positioning portion 73 is connected to a second end of a corresponding first bending portion 72, and one end of each second bending portion 74 is connected to a second end of a corresponding positioning portion 73.

[0052] The positioning portion 73 of each of the conductive sheets 7 is bent toward a first side of each of the conductive sheets 7 to form a positioning groove, and the first bending portion 72 and the second bending portion 74 of each of the conductive sheets 7 are bent toward a second side of each of the conductive sheets 7 to form a first limiting slope 721 and a second limiting slope 741. Each positioning groove is configured to engage with a conductive contact 52 of a corresponding rotating end 51 of each of the first rotating pins 5 when the first rotating pins 5 of the plug is in the use state, so that the first rotating pins 5 are positioned.

[0053] The plug with linked flipping pins comprises the conductive sheets 7. Each of the conductive sheets 7 comprises the mounting portion 71, the first bending portion 72, the positioning portion 73, and the second bending portion 74. The positioning portion 73 of each of the conductive sheets 7 is bent toward the first side of each of the conductive sheets 7 to form the positioning groove, Each positioning groove is configured to engage with the conductive contact 52 of the corresponding rotating end 51 of each of the first rotating pins 5 when the first rotating pins 5 of the plug is in the use state, so that the two first rotating pins 5 are well positioned, the first rotating pins 5 are more reliably maintained in a fully erected state, and the plug is easily plugged into a power outlet. In addition, the first bending portion 72 and the second bending portion 74 , respectively disposed on two ends of the corresponding positioning portion 73, of each of the conductive sheets 7 are bent toward the second side of each of the conductive sheets 7.

[0054] The first bending portion 72 and the second being portion 74 of each of the conductive sheets 7 further enhance an abutting effect of the corresponding positioning portion 73 against the conductive contact 52 of the rotating end 51 of a corresponding first rotating pin 5, thereby ensuring electrical connections between the conductive sheets 7 and the first rotating pins 5. At the same time, the first limiting slope 721 and the second limiting slope 741 of each of the conductive sheets 7 are formed by bending at two ends of a corresponding positioning groove. The first limiting slope 721 and the second limiting slope 741 of each of the conductive sheets 7 and the corresponding positioning groove jointly limits a position of a corresponding conductive contact 52, thereby well positioning the first rotating pins 5.

[0055] In addition, when each conductive contact 52 is rotated from an outside of a corresponding positioning groove through a corresponding second bending portion 74 into the corresponding positioning groove. Since each second bending portion 74 is bent, each second bending portion 74 provides a corresponding first rotating pin 5 with a rotating "feeling" (i.e., each of the first rotating pins 5 is lifted up by each second bending portion 74 and each of the first rotating pins 5 is suddenly fallen into each positioning groove), thereby improving the user experience.

[0056] Specifically, the positioning portion 73, the first bending portion 72, and the second bending portion 72 of each of the conductive sheets 7 are respectively bent toward two sides of each of the conductive sheets 7. The conductive sheets 7 may be copper sheets.

[0057] The rotating end 51 of each of the first rotating pins 5 is inserted into one side of the housing 1 and is rotatably mounted in the housing 1. Each of the conductive sheets 7 is mounted in the housing 1 and corresponds to the rotating end 51 of each of the first rotating pins 5. When the first rotating pins 5 are in the use state, the conductive contact 52 of the rotating end 51 of each of the first rotating pins 5 is clamped in the corresponding positioning groove to position each of the first rotating pins 5.

[0058] Furthermore, the housing 1 comprises mounting columns 115, and the inner pressing cover 6 comprises fitting grooves 62 corresponding to the mounting columnsll5. Each mounting portions 71 defines a mounting hole 711. Each of the conductive sheets 7 is mounted on a corresponding mounting columns 115 through the mounting hole 711 thereof The inner pressing cover 6 is pressed on the conductive sheets 7, and the mounting columns 115 are respectively inserted into the fitting grooves 62. The inner pressing cover 6 is mounted in the housing 1. Each of the conductive sheets 7 is mounted on a corresponding mounting columns 115 through a corresponding mounting hole 711. The inner pressing cover 6 is pressed on the conductive sheets 7 through the fitting grooves 62 and the mounting columns 115, so that the conductive sheets 7 are stably mounted.

[0059] The housing 1 comprises a front cover 11 and a rear cover (not shown in the drawings), the rotating end 51 of each of the first rotating pins 5 is inserted into the housing 1 from one side of the front cover 11. The mounting columns 115 are disposed on the front cover 11. The front cover 11 covers on the rear cover, the inner pressing cover 6 is mounted in the front cover 11 and the rear cover, and the rotating end 51 of each of the first rotating pins 5 is rotatably mounted between the front cover 11 and the inner pressing cover 6.

[0060] Furthermore, each of the conductive sheets 7 further comprises an extension portion 75. One end of each extension portion 75 is connected to one end of a corresponding second bending portion 74 away from the corresponding positioning portion 73. Each extension portion 75 always abuts against the conductive contact 52 of the rotating end 51 of each of the first rotating pins 5 when each of the first rotating pins 5 of the plug is rotated from the storage state to the use state. Each extension portion 75 enables each of the conductive sheets 7 to always abut against the conductive contact 52 of the rotating end 51 of each of the first rotating pins 5, ensuring that each conductive contact 52 is always in contact with a corresponding conductive sheet 7. Therefore, when each conductive contact 52 rotates, each conductive contact 52 directly enters a corresponding positioning groove along a corresponding extension portion 75, so that each conductive contact 52 is not separated from the corresponding conductive sheet 7 in the storage state or before being rotated into the corresponding positioning groove, and each conductive contact 52 does not interfere with the corresponding conductive sheet 7. Thus, the rotation of the first rotating pins 5 is not affected. Specifically, each conductive contact 52 abuts against a surface of each extension portion 75 on the same side as a bending side of a corresponding first bending portion 72 and a bending side of the corresponding second bending portion 74.

[0061] Each extension portion 75 is bending outwards, and a bending direction of each extension portion 75 is on the same side as a bending direction of the corresponding positioning portion 73. In the embodiment, each extension portion 75 is bending, and the bending direction of each extension portion 75 is on the same side as the bending direction of the corresponding positioning portion 73, so that each extension portion 75 is more easily pressed against a corresponding conductive contact 52. At the same time, a bending degree of each extension portion 75 is consistent with a rotation trajectory of the corresponding conductive contact 52, which facilitates a rotation of each conductive contact 52.

[0062] Furthermore, as shown in FIG. 2, an included angle a formed between each extension portion 75 and a corresponding mounting portion 71 at a bending side of the corresponding first bending portion 72 and the corresponding second bending portion 74 is 90°-160°. The included angle a is 90°-160°, so that each extension portion 75 provides a more appropriate and sufficient resistance to the corresponding conductive contact 52, ensuring that each extension portion 75 is in contact with the corresponding conductive contact 52, and ensuring that each of the first rotating pins 5 is easy to rotate. Specifically, the included angle a is selected from 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, and 160°. Optionally, the included angle a is 130°-150°.

[0063] Furthermore, each mounting portion 71 defines mounting holes 711 for mounting each of the conductive sheets 7 in the plug. The mounting holes 711 of each mounting portion 71 are configured to mount and fix each of the conductive sheets 7. Mounting columns!15 are disposed in the housing 1 of the plug, and the mounting holes 711 are one-to-one sleeved on the mounting columns 115 to realize the mounting of the conductive sheets 7.

[0064] Each of the conductive sheets 7 further comprises an electrical connecting portion 76. Each electrical connecting portion 76 is configured to connect to a corresponding wire in the plug. Each electrical connecting portion 76 is tilted toward a bending side of a corresponding positioning portion 73. In the embodiment, each electrical connecting portion 76 is tilted toward the bending side of the corresponding positioning portion 73, so that each electrical connecting portion 76 is allowed to extend from a corresponding opening 63 on the inner pressing cover 6 of the plug and tilt, so that each electrical connecting portion 76 is electrically connected to the corresponding wire. Each electrical connecting portion 76 is welded to the corresponding wire by soldering. Specifically, each electrical connecting portion 76 comprises a connecting hole 761 configured to connect to the corresponding wire in the plug. Each wire is connected to a corresponding connecting hole 761, ensuring a firm connection between each electrical connecting portion 76 and the corresponding wire.
