Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

In one embodiment, referring to fig. 2, a rotating plug assembly 10, the rotating plug assembly 10 includes: a conductive sheet 100, a stopper 200, and a plug structure 300. The limiting member 200 is provided with a first limiting portion 210 and a second limiting portion 220 at an interval. The first position-limiting portion 210 and the second position-limiting portion 220 form an included angle. The plug structure 300 includes a conductive shaft 310, a stopper 320, and at least two pins 330. At least two pins 330 are disposed at intervals and electrically connected to the conductive shaft 310. The limiting block 320 is connected to the conductive rotating shaft 310 and abuts against the limiting member 200. The conductive shaft 310 is electrically connected to the conductive sheet 100. When the plug 330 rotates around the axis of the conductive shaft 310 to the retracted position, the limiting block 320 is in limiting fit with the first limiting portion 210. When the pin 330 rotates around the axis of the conductive shaft 310 to the working position, the limiting block 320 is in limiting fit with the second limiting portion 220.

In the above-mentioned rotary plug assembly 10, the conductive sheet 100 is always electrically connected to the conductive shaft 310, which is beneficial to improving the stability and reliability of the conductive contact during the rotation of the pin 330. In addition, the limiting block 320 is disposed on the conductive rotating shaft 310, so that not only the space occupied by the plug structure 300 can be reduced, but also when the plug pins 330 rotate around the axis of the conductive rotating shaft 310 to the folding position or the working position, the limiting block 320 can be respectively in limiting fit with the first limiting portion 210 and the second limiting portion 220 on the limiting member 200, so as to limit the plug structure 300.

It should be noted that, when the plug 330 is disconnected from the utility power and is in the storage state, the plug 330 is in the retracted position; when the pins 330 are connected to the mains electricity, the pins 330 are in the operative position.

It should be further noted that the limiting block 320 is disposed between the two pins 330 connected to the conductive rotating shaft 310 at intervals, so as to fully utilize the space on the conductive rotating shaft 310, which is beneficial to improve the space utilization of the rotating plug assembly 10. In this embodiment, the axis of the conductive rotating shaft 310 is used as a starting point, the extending directions of the two pins 330 are the same, and the extending direction of the limiting block 320 is opposite to the extending direction of the pins 330, so that when the pins 330 rotate around the axis of the conductive rotating shaft 310, the pins 330 can rotate simultaneously, and the limiting block 320 is in limiting contact with the limiting block 200 without affecting the use of the pins 330.

In addition, the first position-limiting portion 210 and the second position-limiting portion 220 may be provided with a recess 230 capable of engaging with the position-limiting block 320, so that when the plug pin 330 rotates to the retracted position (or the working position) around the axis of the conductive rotating shaft 310, the position-limiting block 320 and the first position-limiting portion 210 (or the second position-limiting portion 220) are stably limited, so as to improve the stability of the plug pin 330 in the retracted position (or the working position), and to prevent the problems of loosening of the rotating plug assembly 10 and the like caused by unstable position limitation.

Specifically, in the present embodiment, the second position-limiting portion 220 is provided with a recessed portion 230 at a position close to the first position-limiting portion 210, so that when the pin 330 is located at the working position, an end of the position-limiting block 320 facing away from the conductive rotating shaft 310 can engage with the recessed portion 230, so that the pin 330 is stably kept at the working position.

It is understood that the conductive sheet 100, the conductive shaft 310, and the pins 330 are all conductive elements. The position-limiting member 200 is an elastic member having elasticity.

In one embodiment, referring to fig. 2, the first position-limiting portion 210 and the second position-limiting portion 220 form an obtuse angle. The stopper 320 abuts against at least one of two side surfaces of the first stopper portion 210 and the second stopper portion 220 forming an obtuse angle.

It should be noted that when the limiting block 320 rotates around the axis of the conductive rotating shaft 310, the limiting block 320 can slide on one of two side surfaces of the first limiting portion 210 and the second limiting portion 220 which form an obtuse angle (angle θ in fig. 4). When the stopper 320 moves to the joint of the first stopper portion 210 and the second stopper portion 220, the stopper 320 abuts against two side surfaces of the first stopper portion 210 and the second stopper portion 220 forming an obtuse angle.

Here, the direction of the pins 330 rotating from the working position to the retracted position is defined as a first direction (indicated by an arrow S in fig. 7), and the direction of the pins 330 rotating from the retracted position to the working position is defined as a second direction (indicated by an arrow T in fig. 7), where the first direction is opposite to the second direction.

When the plug 330 is in the retracted position, referring to fig. 6, the length direction of the plug 330 is parallel to the plane of the second position-limiting portion 220, and the position-limiting block 320 abuts against the first position-limiting portion 210. At this time, the first position-limiting portion 210 applies an upward pushing force to the position-limiting block 320, so that the plug 330 can rotate in the first direction to prevent the plug 330 from rotating back to the working position.

When the plug 330 is at the working position, referring to fig. 7, the length direction of the plug 330 is perpendicular to the plane of the second position-limiting portion 220, and the position-limiting block 320 abuts against the recess 230 of the second position-limiting portion 220. At this time, the stopper 320 engages with the recess 230 to stabilize the pin 330.

In addition, the included angle between the first position-limiting portion 210 and the second position-limiting portion 220 is 120-160 °. Specifically, in this embodiment, an included angle formed between the first position-limiting portion 210 and the second position-limiting portion 220 is 140 °, and the first position-limiting portion 210 and the second position-limiting portion 220 respectively have the best position-limiting effect on the position-limiting block 320.

In one embodiment, referring to fig. 2, the number of the conductive sheets 100 is two. The two conductive sheets 100 are electrically connected to two ends of the conductive shaft 310, respectively.

Therefore, the conductive sheet 100 is electrically connected to both ends of the conductive shaft 310, which further improves the stability of the electrical connection in the rotating plug assembly 10.

Further, the two conductive sheets 100 are directly connected to two ends of the conductive rotating shaft 310, so that the conductive sheets 100 and the conductive rotating shaft 310 can be directly and mechanically connected and electrically connected, which is beneficial to reducing the number of necessary components and optimizing the internal space of the rotating plug assembly 10.

It should be noted that, although two conductive sheets 100 are directly connected to two ends of the conductive rotating shaft 310, during the rotation of the conductive rotating shaft 310 around its own axis, the conductive sheet 100 is in a fixed state, that is, the conductive sheet 100 does not rotate with the rotation of the conductive rotating shaft 310. Therefore, the electronic element electrically connected to the end of the conductive sheet 100 away from the conductive rotating shaft 310 can be ensured without being affected by the rotation of the conductive rotating shaft 310.

Specifically, in the present embodiment, the electronic component electrically connected to the end of the conductive sheet 100 away from the conductive rotating shaft 310 is a circuit board.

In one embodiment, referring to fig. 1 and 2, an adapter 1 includes a housing 20, a cover plate 30, and a rotating plug assembly 10 of any one of the above. A bottom wall 21 is provided within the housing 20 for carrying the rotary plug assembly 10. The conductive sheet 100 and the stopper 200 are connected to the bottom wall 21. The cover plate 30 covers the plug structure 300 and is detachably connected to the bottom wall 21.

It can be seen that the cover plate 30 covers the plug structure 300 on the bottom wall 21 to connect the plug structure 300 to the housing 20. Meanwhile, when it is necessary to replace some or all of the components in the plug structure 300, the connection between the cover plate 30 and the bottom wall 21 may be released, so that the plug structure 300 is separated from the housing 20.

In addition, the limiting member 200 and the conductive sheet 100 are detachably connected to the bottom wall 21. The detachable connection mode can be a screw joint mode, a pin joint mode, a clamping mode and the like. Specifically, in the present embodiment, the limiting member 200 and the conductive sheet 100 are both screwed with the bottom wall 21.

It should be noted that the second position-limiting portion 220 of the position-limiting member 200 is attached to the bottom wall 21 and screwed to the bottom wall 21, and the first position-limiting portion 210 forms an included angle with the bottom wall 21.

In one embodiment, referring to fig. 2, the housing 20 is formed with a groove 22. The grooves 22 correspond to the pins 330 one to one. The recess 22 is used to receive the pin 330. When the pins 330 are rotated to the retracted position, the pins 330 are disposed in the grooves 22.

It can be seen that the slots 22 provide a space for the pins 330 to rest when the pins 330 are rotated to the retracted position.

It should be noted that the recess direction of the groove 22 is the same as the rotation direction of the plug 330 when rotating to the retracted position along the first direction. Therefore, when the plug 330 rotates to the retracted position, the first position-limiting portion 210 pushes the plug 330 to rotate along the first direction, and the groove 22 can prevent the plug 330 from rotating along the first direction. That is, the first position-limiting portion 210 and the groove 22 jointly act on the pins 330, so that the pins 330 can be kept stable in the retracted position, which is beneficial for the pins 330 to be stably received in the groove 22 when the adapter 1 is not in use.

In one embodiment, referring to fig. 2, the bottom wall 21 is provided with a first positioning portion 211. The cover plate 30 is provided with a second positioning portion 31. The first positioning portion 211 is detachably connected to the second positioning portion 31.

Alternatively, the first positioning portion 211 has a convex structure, and the second positioning portion 31 has a groove or hole structure; alternatively, the first positioning portion 211 has a groove or hole structure, and the second positioning portion 31 has a convex structure. In addition, the first positioning portion 211 and the second positioning portion 31 may be both provided with screw holes, so that the cover plate 30 may be detachably screwed on the bottom wall 21 by sequentially passing through the second positioning portion 31 and the first positioning portion 211 by screws.

Specifically, in the present embodiment, the first positioning portion 211 and the second positioning portion 31 are both configured with threaded holes.

In one embodiment, referring to fig. 2, the adapter 1 further includes a circuit board (not shown). The conductive sheet 100 is provided with a first contact 110 and a second contact 120. The first contact portion 110 is electrically connected to the conductive shaft 310. The second contact portion 120 is electrically connected to the circuit board.

Therefore, the first contact portion 110 is electrically connected to the conductive shaft 310, and the second contact portion 120 is electrically connected to the circuit board, so that the circuit board and the conductive shaft 310 can be prevented from interfering with each other when the conductive shaft 310 rotates.

The second contact portion 120 may be connected to the circuit board by clamping, welding, or the like, as long as the conductive sheet 100 can be electrically connected to the circuit board.

Further, in the present embodiment, the second contact portion 120 extends with at least two conductive strips 121. At least two conductive strips 121 are used to hold the circuit board. Therefore, by using the conductive strips 121 to clamp the circuit board, the conductive sheet 100 and the circuit board are kept independent, and the conductive sheet 100 and/or the circuit board can be conveniently and specifically adjusted and replaced when needed.
