[0026] 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.
[0027] See also Figure 1 and Figure 6 The present application provides a plug assembly 100, which is used to be plugged and connected with a socket assembly 200 or an electronic device to form the transmission of electric energy and data signals. The plug assembly 100 includes a first connector 10, a first circuit board 20, a first switch 30 and a locking component 40. The first connector 10 includes a first detection terminal 11, a detection circuit (not shown) is provided on the first circuit board 20, and the first detection terminal 11 is connected to the first circuit board 20 through the detection circuit. The first detection terminal 11 is used to connect with the detection terminal on the socket assembly 200 or the electronic device to trigger a power-on signal or a power-off signal, so as to control whether the first connector 10 is electrically conductive with the socket assembly 200 or the electronic device. The first switch 30 is arranged on the first circuit board 20 and is electrically connected to the detection circuit. The locking component 40 is disposed on the first circuit board 20 and connected to the first switch 30. The locking component 40 is configured to lock or unlock the first connector 10 plugged into the socket assembly 200, and the locking component 40 also controls the first switch 30 to realize the connection or disconnection of the detection circuit.
[0028] Specifically, see Figure 1 and Figure 7 In the initial state, the locking component 40 controls the first switch 30 to make the detection circuit in the on state. When the first connector 10 is plugged into the socket assembly 200, the other terminals 12 on the first connector 10 first contact with the terminals 2012 on the socket assembly 200, and then the first detection terminal 11 on the first connector 10 contacts with the detection terminal 2011 on the socket assembly 200 and triggers the power-on signal. The locking component 40 locks the first connector 10 on the socket assembly 200 to ensure the stability of the connection between the two. When the first connector 10 needs to be separated from the socket assembly 200, By applying force on the locking component 40, the locking component 40 presses the first switch 30 to control the detection circuit to be in an open circuit state to trigger a power-off signal, so that the other terminals 12 on the first connector 10 are not electrically connected to the terminals 2012 on the socket assembly 200. The locking component 40 unlocks the first connector 10 from the socket assembly 200. At this time, when the first connector 10 is not electrically connected to the socket assembly 200, the first connector 10 is pulled out and separated from the socket assembly 200, which can avoid arcing and ensure the safety of the plug assembly 100 and the socket assembly 200. At the same time, the locking component 40 has the function of locking and unlocking the first connector 10, and also has the function of controlling the first switch 30 to control the detection circuit to be in a pass state or an open circuit state. The user only needs to press the locking component 40 to complete the triggering of the power-off signal and unlocking the first connector 10, which greatly reduces the defective rate and improves the stability of the product.
[0029] In some embodiments, see Figure 1 and Figure 2 The first connector 10 includes a first body 13, and the locking component 40 includes a button 41 and a locking member 42. The locking member 42 is movably arranged on the first body 13. The button 41 is respectively connected to the first switch 30 and the locking member 42. The button 41 is configured to receive a force to press the first switch 30 so as to control the detection circuit to an open circuit state to trigger a power-off signal, and drive the locking member 42 to move to unlock the first connector 10.
[0030] The locking member 42 can be slidably disposed on the first body 13, or can be rotatably disposed on the first body 13. As one example, see Figure 2 and Figure 3The first locking member 42 includes a first rotating portion 421, and the first body 13 is provided with a second rotating portion 131, and the first rotating portion 421 and the second rotating portion 131 are rotatably connected. When the button 41 drives the locking member 42 to move, the locking member 42 rotates relative to the first circuit board 20, so that the locking member 42 has a locking position and an unlocking position relative to the first circuit board 20, and the button 41 drives the locking member 42 to switch between the locking position and the unlocking position. When the locking member 42 is in the locking position, the locking member 42 locks the first connector 10 on the socket assembly 200; when the locking member 42 is in the unlocking position, the first connector 10 can be separated relative to the socket assembly 200.
[0031] Furthermore, the locking member 42 has a first end and a second end opposite to each other, and the first rotating portion 421 can be disposed at the first end of the locking member 42, or between the first end of the locking member 42 and the second end of the locking member 42. As an example, refer to Figure 2 The first rotating portion 421 is disposed between the first end of the locking member 42 and the second end of the locking member 42. The first end of the locking member 42 is provided with a first locking hook 422. The button 41 is connected to the second end of the locking member 42. Figure 3 , Figure 3 It is a schematic diagram of the locking member 42 in the locking position. When observed in a direction perpendicular to the surface of the first circuit board 20, when the locking member 42 is in the locking position, the first locking hook 422 protrudes from the first connector 10. When the locking member 42 is in the unlocking position, the first locking hook 422 is located in the first connector 10.
[0032] In some implementations, see Figure 4 The locking component 40 further includes a first reset member 43, which is connected to the button 41 and the locking member 42 respectively, and supports the button 41. The first reset member 43 is configured to drive the button 41 and the locking member 42 to reset, that is, to drive the locking member 42 to reset from the unlocked position to the locked position and remain in the locked position, and at the same time drive the button 41 to move in a direction away from the first switch 30, so that the button 41 does not press the first switch 30, so that the detection circuit remains in a conductive state.
[0033] In some embodiments, see Figure 3 and Figure 4 There are two locking members 42, which are respectively arranged on both sides of the first switch 30. The first reset member 43 includes a first straight section 431, a bent section 432 and a second straight section 433 which are sequentially connected. The first straight section 431 and the second straight section 433 are respectively arranged on both sides of the bent section 432. Figure 5, wherein the first straight section 431 and the second straight section 433 are in the same plane, while the bent section 432 is not in the same plane as the first straight section 431 and the second straight section 433, so that the bent section 432 can be deformed and have an elastic force, and the elastic force is used to drive the locking member 42 and the button 41 to perform a reset movement. The button 41 is arranged on the bent section 432, the first straight section 431 is connected to one of the locking members 42, and the second straight section 433 is connected to the other locking member 42.
[0034] Specifically, see Figure 4 When the first connector 10 needs to be unplugged and separated from the socket assembly 200, a force is applied to the button 41 to drive the button 41 to move in a direction close to the first switch 30. The first switch 30 is pressed to put the detection circuit in an open circuit state. The movement of the button 41 causes the bent section 432 to deform and drives the first straight section 431 and the second straight section 433 to move apart, respectively. The locking member 42 rotates relative to the first circuit board 20, and the second end of the locking member 42 moves in a direction away from the first switch 30, so that the first end of the locking member 42 retracts into the interior of the first connector 10 to be in an unlocked position.
[0035] When the force on the button 41 is released, under the elastic force of the bending section 432, the button 41 is driven to move in a direction away from the first switch 30, so that the first switch 30 controls the detection circuit to restore the circuit state, and the bending section 432 pulls the first straight portion and the second straight portion to move toward each other, and the locking member 42 rotates in the opposite direction relative to the first circuit board 20, that is, the second end of the locking member 42 moves in a direction close to the first switch 30, and the first end of the locking member 42 protrudes from the first connector 10 to restore to the locked position.
[0036] In some embodiments, see Figure 5 The bending section 432 is provided with a first through hole 4321 penetrating therethrough, the button 41 comprises a second body 411 and an extension column 412 connected to each other, the second body 411 is located at a side of the bending section 432 away from the first switch 30, and the extension column 412 is passed through the first through hole 4321 and abuts against the first switch 30. By providing the extension column 412 on the button 41, the button 41 can be easily abutted against the first switch 30 to adapt to the structure of the arched bending portion.
[0037] In some embodiments, see Figure 1 and Figure 4The locking component 40 further includes a second reset member 44, which is connected to the first switch 30 and the extension column 412 respectively, so as to further increase the reset capability of the button 41, and prevent the button 41 from always pressing on the first switch 30, causing the detection circuit to remain in the disconnected state. It can be understood that the first reset member 43 can be a part with elastic deformation capability such as a spring, a pressure sheet, or a compression spring, and the second reset member 44 can be a spring, etc.
[0038] In some embodiments, see Figure 1 and Figure 3 The side wall of the first connector 10 is provided with a second through hole 14 therethrough. When the locking piece 42 is in the locking position, the first locking hook 422 of the locking piece 42 protrudes from the first connector 10 through the second through hole 14. Thus, when the first connector 10 is plugged into the socket assembly 200, the protruding first locking hook 422 can engage with the socket assembly 200 to lock the first connector 10 on the socket assembly 200.
[0039] The present application also provides an embodiment of a connector device 1000, see Figure 6 The connector device 1000 includes a socket assembly 200 and a plug assembly 100 in any of the above embodiments. The socket assembly 200 includes a second connector 201, and the second connector 201 includes a second detection terminal 2011. The second detection terminal 2011 is configured to connect with the first detection terminal 11 when the first connector 10 and the second connector 201 are connected to trigger a power-on signal. The specific structure and function of the plug assembly 100 can be referred to the above embodiments, and will not be repeated here.
[0040] It is worth mentioning that please refer to Figure 2 and Figure 7 In addition to the first detection terminal 11, the first connector 10 on the plug assembly 100 also includes other terminals; in addition to the second detection terminal 2011, the second connector 201 on the socket assembly 200 also includes other terminals; the other terminals on the first connector 10 are connected with the other terminals on the second connector 201 to realize the transmission of power and data between the plug assembly 100 and the socket assembly 200, and the first detection terminal 11 is used to connect with the second detection terminal 2011 to control the power on or off of the other terminals on the first connector 10 and the other terminals on the second connector 201.
[0041] In some embodiments, see Figure 7The socket assembly 200 also includes a shell 202, and the second connector 201 is at least partially arranged inside the shell 202. The side wall of the shell 202 is also provided with a third through hole 2021, and the third through hole 2021 is configured to be connected with the first locking hook 422 in the locking component 40, so that the first connector 10 is locked in the second connector 201, avoiding the first connector 10 and the second connector 201 from separating in an electrically conductive state and generating an arc phenomenon, thereby enhancing the stability of the connection between the first connector 10 and the second connector 201 and ensuring the safety of the plug assembly 100 and the socket assembly 200.
