[0028] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0029] The present application provides a plug assembly 100, which is applied to an electronic device. The plug assembly 100 is used to be plugged with a socket assembly 201 in the electronic device to form an electrical connection, so as to supply power to the electronic device and transmit signals. Figure 1 and Figure 2The plug assembly 100 includes a first connector 10, a first circuit board 20, a first cable 30 and a first switch 41. The first connector 10 includes a first detection terminal 11, and the first connector 10 is electrically connected to the first circuit board 20. The first circuit board 20 is provided with a connection circuit 21, and the first detection terminal 11 on the first connector 10 is connected to the first cable 30 through the connection circuit 21. The first switch 41 is arranged on the first circuit board 20 and connected to the connection circuit 21, and the first switch 41 is configured to conduct or disconnect the connection circuit 21. When the plug assembly 100 needs to be unplugged from the electronic device, the user disconnects the connection circuit 21 by pressing the first switch 41, and at this time, a power-off signal is triggered to disconnect the power between the first connector 10 and the electronic device, and then the plug assembly 100 is unplugged and separated, which can effectively avoid the arc phenomenon caused by the direct unplugging of the first connector 10 and the electronic device in the state of electrical conduction, and can effectively protect the plug assembly 100 and the electronic device, and increase the service life and safety of both.

[0030] For the above-mentioned plug assembly 100, please refer to Figure 1 and Figure 2 The plug assembly 100 further includes a first housing 50 and a first pressing portion 61. Part of the first connector 10, the first circuit board 20, the first switch 41 and part of the first cable 30 are arranged inside the first housing 50. The first pressing portion 61 is connected to the first housing 50 and the first switch 41 respectively. The first pressing portion 61 is configured to receive an external force to drive the first switch 41 to connect or disconnect the connection circuit 21. By providing a structure in which the first pressing portion 61 is connected to the first switch 41, the contact area of ​​the user pressing the first switch 41 can be increased, and the difficulty of pressing can be reduced.

[0031] For the first housing 50 mentioned above, please refer to Figure 1 and Figure 3 , along the first direction X, the first shell 50 has a first side portion 51 and a second side portion 52 that are arranged opposite to each other. Along the second direction Y, the first shell 50 has a top portion 53 and a bottom portion 54 that are arranged opposite to each other. Among them, the first direction X and the second direction Y are perpendicular to each other. The first pressing portion 61 is arranged on one of the first side portion 51, the second side portion 52, the top portion 53 and the bottom portion 54 of the first shell 50. Since the first pressing portion 61 is connected to the first switch 41, when separating the plug assembly 100 from the electronic device, the user only needs to apply force to press the first pressing portion 61 to drive the first switch 41 to disconnect the connection circuit 21, and there is no specific restriction on the position of the first pressing portion 61 on the first shell 50.

[0032] In some embodiments, see Figure 2, the plug assembly 100 further includes a second pressing portion 62, which is connected to the first shell 50, and is disposed on one of the first side portion 51, the second side portion 52, the top portion 53 and the bottom portion 54 of the first shell 50, and the first pressing portion 61 and the second pressing portion 62 are disposed adjacent to or opposite to each other on the first shell 50. When the user unplugs the plug assembly 100, a force is usually applied to the adjacent or opposite surface of the first shell 50, so that the first pressing portion 61 and the second pressing portion 62 are disposed at adjacent positions or opposite positions on the first shell 50, which can further reduce the difficulty of unplugging the plug assembly 100. In a further example, the first pressing portion 61 and the second pressing portion 62 are preferably disposed opposite to each other in the first direction X or in the second direction Y, so that the user can press the first pressing portion 61 and the second pressing portion 62 on the first shell 50 by, for example, pinching two fingers, which is more in line with the user's operating habits.

[0033] For the above-mentioned plug assembly 100, please refer to Figure 4 The plug assembly 100 further includes a second switch 42, which is disposed on the first circuit board 20 and connected to the second pressing portion 62. The second switch 42 is connected to the connection circuit 21, and the second pressing portion 62 is configured to receive an external force to drive the second switch 42 to turn on or off the connection circuit 21. By arranging the first switch 41 and the second switch 42 on the connection circuit 21, the first switch 41 and the second switch 42 can form a synergistic effect or a redundant design.

[0034] As another example, see Figure 4 The first switch 41 and the second switch 42 are arranged in series on the connection circuit 21, so that pressing one of the first switch 41 and the second switch 42 can disconnect the connection circuit 21, and the pressable area on the first housing 50 can be increased. Therefore, the first switch 41 and the second switch 42 in this example form a redundant design. In this example, the first switch 41 and the second switch 42 are preferably arranged adjacent to each other on the first housing 50, so that the user can trigger the power-off signal regardless of whether he presses the first housing 50 in the first direction X or in the second direction Y.

[0035] As an example, see Figure 5 The first switch 41 and the second switch 42 are arranged in parallel on the connection circuit 21, so that the connection circuit 21 can be disconnected only when both the first switch 41 and the second switch 42 are pressed, thereby preventing power failure caused by accidentally touching the first switch 41 or the second switch 42. Therefore, the first switch 41 and the second switch 42 in this example form a synergistic effect. In this example, the first switch 41 and the second switch 42 are preferably arranged relative to each other in the first direction X or the second direction Y.

[0036] For the first housing 50 mentioned above, please refer to Figure 6 The first housing 50 is provided with a first groove 55 and a first through hole 56. The first groove 55 is configured to accommodate at least part of the first pressing portion 61. The first through hole 56 communicates the first groove 55 with the interior of the first housing 50. A portion of the first switch 41 is inserted through the first through hole 56 and connected to the first pressing portion 61. By providing the first groove 55 on the first housing 50, on the one hand, at least part of the first pressing portion 61 can be accommodated. On the other hand, it can be prevented that the interior of the first housing 50 is directly exposed due to the first pressing portion 61 being provided on the first housing 50, and that external water vapor and debris directly enter the interior of the first housing 50 to interfere with components such as the first circuit board 20. By providing the first through hole 56, a portion of the first switch 41 is inserted through so as to be connected to the first pressing portion 61. Of course, the first switch 41 can also be sealed at the first through hole 56 to further reduce the direct entry of water vapor and debris into the interior of the first housing 50.

[0037] Similarly, in the example where the plug assembly 100 includes the first pressing portion 61 and the second pressing portion 62, the first housing 50 is further provided with a second groove 57 and a second through hole 58, the second groove 57 is configured to accommodate at least a portion of the second pressing portion 62, the second through hole 58 communicates the second groove 57 with the interior of the first housing 50, a portion of the second switch 42 is passed through the second through hole 58, and is connected to the second pressing portion 62. The functions of the second groove 57 and the second through hole 58 can be referred to the first groove 55 and the first through hole 56 described above, and will not be described in detail here.

[0038] The present application also provides a connector device 200, which includes a socket assembly 201 and a plug assembly 100 in any of the above embodiments. The socket assembly 201 can be provided in an electronic device or can be an independent component. Figure 1 The first connector 10 further includes a first terminal group 12, and the first terminal group 12 is configured to transmit power and signal data. Figure 7 and Figure 8, the socket assembly 201 includes a second connector 202 and a second circuit board 203, the second connector 202 is arranged on the second circuit board 203, and the second connector 202 includes a second terminal group 2022 and a second detection terminal 2021. The second terminal group 2022 is configured to transmit power and signal data. The first detection terminal 11 and the second detection terminal 2021 are configured to trigger a power-off signal, so that the electrical connection between the first terminal group 12 and the second terminal group 2022 is disconnected to avoid arcing when the plug assembly 100 and the socket assembly 201 are plugged in the third direction Z, the first connector 10 is plugged in with the second connector 202, so that the first terminal group 12 is connected to the second terminal group 2022, and when the first detection terminal 11 is connected to the second detection terminal 2021, the power-on signal is triggered, so that the first terminal group 12 and the second terminal group 2022 form power transmission and signal data transmission. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. When it is necessary to separate the plug assembly 100 and the socket assembly 201, force is applied to the first pressing portion 61 and / or the second pressing portion 62 to trigger the first switch 41 and / or the second switch 42, disconnect the connection circuit 21, trigger a power-off signal, and thereby disconnect the electrical connection between the first terminal group 12 and the second terminal group 2022, and then the plug assembly 100 is pulled out and separated from the socket assembly 201. This can effectively avoid arcing caused by directly pulling out the first connector 10 and the second connector 202 when they are electrically connected, and can effectively protect the plug assembly 100 and the socket assembly 201, thereby increasing the service life and safety of both.

[0039] For the above-mentioned socket assembly 201, please refer to Figure 7 and Figure 8 The socket assembly 201 further includes a second housing 204, at least part of the second connector 202 and the second circuit board 203 are arranged inside the second housing 204, and the second housing 204 is provided with a first buckling portion 2041. The end of the first pressing portion 61 on the plug assembly 100 is provided with a second buckling portion 611, and when the plug assembly 100 and the socket assembly 201 are plugged in the third direction Z, the first buckling portion 2041 and the second buckling portion 611 are buckled and connected. When the plug assembly 100 and the socket assembly 201 are separated, while applying force on the first pressing portion 61 to drive the first switch 41 to move, the first buckling portion 2041 moves and separates from the second buckling portion 611, and then the plug assembly 100 is driven to separate from the socket assembly 201 in the third direction Z. By providing the second buckling portion 611 on the first pressing portion 61, when a force is applied to the first pressing portion 61, the first switch 41 can be pressed and the first buckling portion 2041 and the second buckling portion 611 can be unlocked simultaneously, thereby improving the convenience of operation.

[0040] In other embodiments, the second housing 204 is further provided with a third buckling portion 2042, and the second pressing portion 62 on the plug assembly 100 is provided with a fourth buckling portion 621, and when the first housing 50 and the second housing 204 are plugged in the third direction Z, the third buckling portion 2042 is buckled and connected with the fourth buckling portion 621. The structure and function of the fourth buckling portion 621 provided on the second pressing portion 62 can refer to the structure and function of the second buckling portion 611 provided on the first pressing portion 61, and will not be repeated here.

[0041] In some embodiments, see Figure 5 , along the third direction Z, the second buckle portion 611 extends beyond the first housing 50. And / or, along the third direction Z, the fourth buckle portion 621 extends beyond the first housing 50. Through the above-mentioned structural arrangement, when the plug assembly 100 and the socket assembly 201 are plugged and connected, the second buckle portion 611 and the fourth buckle portion 621 can extend into the second housing 204, thereby enhancing the firmness of the connection between the plug assembly 100 and the socket assembly 201.

[0042] The plug assembly 100 of the embodiment of the present application includes a first connector 10, a first circuit board 20, a first cable 30 and a first switch 41. The first connector 10 includes a first detection terminal 11, and the first connector 10 is electrically connected to the first circuit board 20. The first circuit board 20 is provided with a connection circuit 21, and the first detection terminal 11 on the first connector 10 is connected to the first cable 30 through the connection circuit 21. The first switch 41 is arranged on the first circuit board 20 and connected to the connection circuit 21, and the first switch 41 is configured to conduct or disconnect the connection circuit 21. When the plug assembly 100 needs to be unplugged from the electronic device, the user disconnects the connection circuit 21 by pressing the first switch 41, and at this time, a power-off signal is triggered to disconnect the power between the first connector 10 and the electronic device, and then the plug assembly 100 is unplugged and separated, which can effectively avoid the arc phenomenon caused by the direct unplugging of the first connector 10 and the electronic device in the state of electrical conduction, and can effectively protect the plug assembly 100 and the electronic device, and increase the service life and safety of both.
