Description

Technical Field

[0001] This utility model relates to the field of power connection technology, and more specifically to the technology of a magnetically triggered power connection structure. Widely used in power connections for electronic devices such as mobile phones and laptops, this magnetically triggered power connection structure effectively improves the safety and stability of power connections. Background Art

[0002] A power connection structure is a device used to control the on / off state of a circuit and plays a vital role in power systems and electronic equipment. Its basic function is to establish or cut off the current path.

[0003] With the miniaturization and high power demands of electronic devices, the reliability and convenience of power connection structures have become increasingly important. Currently, most power connection devices use traditional mechanical structures, which are widely used due to their simplicity. However, these mechanical connection methods are subject to mechanical wear, resulting in reduced connector reliability after long-term use and potentially posing safety risks.

[0004] Furthermore, the physical contact characteristics of traditional mechanical power connection devices result in slow response times, limiting their performance in applications requiring rapid response. Traditional power connection structures often use mechanical control to turn the power on and off. While this design is simple, it suffers from the following drawbacks:

[0005] 1. The plug is easy to loosen: During repeated plugging and unplugging, the contact point between the plug and the socket may become loose, resulting in poor contact of the plug. Such looseness not only affects the stable connection of the power supply, but may also cause electric sparks and cause fire.

[0006] 2. Leakage safety hazards: In modern electronic devices, the safety and reliability of power connections are crucial. The wires inside traditional sockets are often live and exposed, posing a safety hazard such as accidental electric shock when exposed to conductive media.

[0007] Therefore, it is particularly important to develop a power connection structure that cannot form a circuit loop when the plug is not inserted. Utility Model Content

[0008] The purpose of the present invention is to provide a power connection structure based on magnetic triggering in order to solve the hidden danger that the socket pins in the mechanical power connection device are charged and exposed to the outside, which may easily lead to safety problems.

[0009] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0010] The utility model provides a power connection structure based on magnetic triggering, comprising a socket trigger component and a plug component connected to the socket trigger component. When the socket trigger component and the plug component are not connected, the circuit in the socket trigger component is disconnected. When the socket trigger component and the plug component are connected, the circuit in the socket trigger component is connected.

[0011] In one embodiment, the plug assembly includes a plug housing, two plug pins fixed to the bottom of the plug housing, and a first magnetic element fixed to the inner side of the bottom of the plug housing.

[0012] In one embodiment, a first mounting hole for accommodating the first magnetic element is provided at the bottom of the plug housing. The first mounting hole is located between two plug pins, and a first magnetic element sealing plate is provided at the opening of the first mounting hole.

[0013] In one embodiment, the socket trigger assembly includes a socket housing and a magnetic conduction assembly disposed within the socket housing; a mounting through-hole for mounting the magnetic conduction assembly is disposed within the socket housing and extends vertically therethrough; an upper sealing plate and a lower sealing plate for sealing the mounting through-hole are disposed at both upper and lower ends of the socket housing;

[0014] The magnetic conductive component includes a first shock-absorbing layer, a conductive layer, an insulating layer, a second magnetic element, a second shock-absorbing layer, a third magnetic element, a first conductive terminal, a first conductive wire, and a first connecting terminal;

[0015] The first shock-absorbing layer and the first conductive terminal are fixed in an upper and lower form below the sealing plate on the socket shell and are located at the top of the mounting through-hole. The second shock-absorbing layer is fixed in the middle of the mounting through-hole. A movable gap is provided between the first conductive terminal and the second shock-absorbing layer. The conductive layer, the insulating layer and the second magnetic element are integrated in an upper and lower form and then slidably arranged in the gap. The height of the gap is greater than the sum of the thicknesses of the conductive layer, the insulating layer and the second magnetic element. The gap is the space for the second magnetic element to move up and down. Both ends of the first conductive terminal are connected to the external circuit through the first wire and the first terminal. The middle part of the first conductive terminal is disconnected, and the conductive layer connects the disconnected part of the first conductive terminal to realize the conduction of the first conductive terminal. After the conductive layer leaves the middle part of the first conductive terminal, the first conductive terminal is disconnected.

[0016] The third magnetic element is located below the second shock absorbing layer in the socket housing.

[0017] Specifically, when the plug assembly is inserted into the socket trigger assembly, a pressed contact is formed between the plug pin and the conductive sheet, and the first magnetic element in the plug assembly and the second magnetic element in the socket trigger assembly generate magnetic attraction, so that the plug assembly and the socket trigger assembly are tightly connected to avoid loosening.

[0018] In one embodiment, when the plug assembly is inserted into the socket trigger assembly, the first magnetic element, the second magnetic element, and the third magnetic element are arranged in the same vertical direction and have the same magnetic direction.

[0019] Specifically, when the plug assembly is inserted into the socket trigger assembly, a press-fit contact is formed between the plug pins and the conductive sheet. Under the action of an external force, the plug assembly drives the first magnetic element to above the first shock-absorbing layer. At this point, the first, second, and third magnetic elements are arranged in order from top to bottom, with their centers located on the same straight line and the same magnetic direction, attracting each other. Under the attraction of the first magnetic element, the second magnetic element approaches the first magnetic element, causing the conductive layer to contact the conductive terminal, closing the circuit and conducting the circuit. Simultaneously, as the distance between the first and second magnetic elements decreases, the attraction increases, causing the socket trigger assembly and the second magnetic element to remain stationary, achieving self-locking.

[0020] When the plug assembly is removed from the receptacle trigger assembly, an external force pulls the first magnetic element away from the first damping layer. As the attraction between the first and second magnetic elements decreases, the second magnetic element, attracted by the third magnetic element, moves toward the second damping layer until it stops, separating the conductive layer from the first conductive terminal and disconnecting the circuit. The second and third magnetic elements attract each other and remain stationary, eliminating the resistance and inconvenience associated with traditional receptacles. This instantaneous power supply and disconnection significantly improves safety and convenience.

[0021] In one embodiment, the socket trigger assembly further includes two conductive plates arranged on both sides of the socket housing, second wires connected to the conductive plates, and second wiring terminals connected to ends of the second wires.

[0022] When the plug assembly is inserted into the socket trigger assembly, the upper surface of the socket shell is provided with two plugging holes for plugging in the plug pins. The top parts of the two conductive sheets are located inside the corresponding plugging holes and are pressed into contact with the sides of the corresponding plug pins.

[0023] Specifically, this solution has the following advantages:

[0024] Stability: The magnetic connection relies on a strong magnetic force to maintain close contact between the plug and the socket, forming a press-fit contact between the plug pins and the conductive plate, ensuring that the connection remains stable and reliable even when the device moves or vibrates. Durability: The wear of this structure only occurs during the press-fit contact between the plug pins and the conductive plate during the plug-in and unplugging process, and does not affect the conductive performance. This makes the design highly durable and reliable, ensuring a stable connection during long-term use. The wear of the magnetic connector is greatly reduced, which prolongs the life of the connector and reduces the unstable connection caused by wear. Finally, the metal contacts in this utility model can be isolated from the outside, thereby preventing the impact of physical and chemical changes such as oxidation or corrosion on the contact quality.

[0025] In one embodiment, the third magnetic element is located in the mounting passage below the second shock-absorbing layer and is fixed to the lower cover plate of the socket housing.

[0026] In one embodiment, a plug trigger assembly follower is further included, which includes a plug trigger follower shell that is slidably inserted into the outside of the socket shell. When the plug assembly is inserted into the socket trigger assembly, the two plug pins contact the top of the plug trigger follower shell, and the third magnetic element is located at the bottom outside the socket shell.

[0027] The beneficial effects of the utility model are as follows:

[0028] 1. In contrast, magnetically triggered power connection structures operate by using changes in the magnetic field to connect and disconnect the circuit. Electrical connection to the conductive sheet is achieved through the circuit layout, and this structure remains disconnected when not triggered. This design effectively prevents the circuit from connecting when disconnected, reducing the risk of electric shock and ensuring user safety.

[0029] 2. The circuit closing and opening in this structure are carried out in a completely sealed and insulated space, which is completely waterproof and dustproof.

[0030] 3. Compared with the traditional mechanical structure, the performance of the mechanical power connection of the utility model is mainly affected by the frequency of use. Taking mobile devices (such as mobile phones and laptops) as an example, their connection stability can usually withstand multiple plugging and unplugging. Its problems of mechanical wear and slow response speed make it prone to failure after long-term use, reduce its reliability, and cause safety hazards. However, this structure uses the change in suction between the first magnetic element, the second magnetic element, and the third magnetic element to control the circuit in the air. The three magnetic elements and the conductive terminals can be sealed, which not only has the advantages of dust and corrosion resistance, but also has the advantages of isolating the circuit and preventing electrical leakage of the conductive terminals. In the socket trigger component of this structure, mechanical wear is no longer the main factor affecting the service life of the power connection device. Its service life is mainly affected by magnetic attenuation. Taking the common neodymium iron boron magnet as an example, in the natural environment, the magnetic attenuation is slow, and this structure can still play a role.

[0031] 4. The magnetically triggered power connection structure has shown broad application potential and development prospects due to its advantages such as rapid response, high reliability and long life. In the power connection structure of the present invention, the magnetic conduction component can be interchangeably configured between the plug component and the socket trigger component. Whether the magnetic conduction component is placed at the plug component end or the socket trigger component end, effective magnetic attraction and connection can be achieved. This design significantly enhances the flexibility of the structure and can adapt to the needs of different equipment and environments, thereby improving the convenience and adaptability of use. The magnetically triggered power connection structure is not only suitable for power connection, but also has the function of circuit data transmission.

[0032] 5. The position of the conductive sheet and the contact position and shape of the plug pins can be modified according to specific design requirements, providing greater flexibility and adaptability. The size and configuration of the power connection structure can be adjusted according to actual usage needs to meet the power requirements of different devices and scenarios.

[0033] 6. The power connection structure shown in the present invention is a dual-plug mode, but it can also be used for the neutral and live wire ports of a three-plug to adapt to the connection scenarios of different electrical equipment and improve the compatibility and applicability of the equipment (the present invention includes at least two conductive plates, at least one of which maintains a circuit disconnected state when the structure is not triggered when the external power is connected. The first conductive terminal, the first wire and the first terminal of the power connection component are each composed of two parts, and the electrical connection with the conductive plate is achieved through the circuit layout to ensure that the conductive plate serving as the live wire remains voltage-free when the structure is not triggered. The first conductive terminal, the first wire and the first terminal of the component can be further configured to consist of four parts, and the electrical connection with the conductive plate is achieved through the circuit layout to ensure that the two conductive plates remain current-free when the structure is not triggered).

Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0069] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0070] The utility model provides a power connection structure based on magnetic triggering, including a socket trigger component 2 and a plug component 1 plugged into the socket trigger component 2. When the socket trigger component 2 and the plug component 1 are not plugged in, the circuit in the socket trigger component 2 is disconnected; when the socket trigger component 2 and the plug component 1 are plugged in, the circuit in the socket trigger component 2 is connected.

[0071] In one embodiment, the plug assembly 1 includes a plug housing 11 , two plug pins 12 fixed to the bottom of the plug housing 11 , and a first magnetic element 4 fixed to the inner side of the bottom of the plug housing 11 .

[0072] In one embodiment, a first mounting hole for accommodating the first magnetic element 4 is provided at the bottom of the plug housing 11 . The first mounting hole is located between the two plug pins 12 , and a first magnetic element sealing plate 14 is provided at the opening of the first mounting hole.

[0073] In one embodiment, the socket trigger assembly 2 includes a socket housing 26 and a magnetic conductive assembly disposed within the socket housing 26. The socket housing 26 is provided with a mounting through-hole extending vertically therethrough for mounting the magnetic conductive assembly. An upper socket housing sealing plate 21 and a lower socket housing sealing plate 203 are provided at both upper and lower ends of the socket housing 26 for sealing the mounting through-hole.

[0074] The magnetic conductive assembly includes a first damping layer 22, a conductive layer 23, an insulating layer 24, a second magnetic element 5, a second damping layer 25, a third magnetic element 6, a first conductive terminal 27, a first wire 28 and a first terminal 29;

[0075] The first shock-absorbing layer 22 and the first conductive terminal 27 are fixed in an upper and lower manner below the sealing plate 21 on the socket housing and are located at the top of the mounting through-hole. The second shock-absorbing layer 25 is fixed in the middle of the mounting through-hole. A movable gap is provided between the first conductive terminal 27 and the second shock-absorbing layer 25. The conductive layer 23, the insulating layer 24 and the second magnetic element 5 are integrated in an upper and lower manner and then slidably arranged in the gap. The height of the gap is greater than the sum of the thicknesses of the conductive layer 23, the insulating layer 24 and the second magnetic element 5. The gap provides space for the second magnetic element 5 to move up and down. Both ends of the first conductive terminal 27 are connected to the external circuit through the first wire 28 and the first terminal 29. The middle of the first conductive terminal 27 is disconnected, and the conductive layer 23 cooperates with the disconnected portion in the middle of the first conductive terminal 27 to achieve the connection or disconnection of the first conductive terminal 27.

[0076] The third magnetic element 6 is located below the second shock-absorbing layer 25 in the socket housing 26 .

[0077] Specifically, when the plug assembly 1 is inserted into the socket trigger assembly 2, a pressed contact is formed between the plug pin 12 and the conductive sheet 200, and the first magnetic element 4 in the plug assembly 1 and the second magnetic element 5 in the socket trigger assembly 2 generate a magnetic attraction, so that the plug assembly 1 and the socket trigger assembly 2 are tightly connected to avoid loosening.

[0078] In one embodiment, when the plug assembly 1 is inserted into the socket trigger assembly 2 , the first magnetic element 4 , the second magnetic element 5 , and the third magnetic element 6 are arranged in the same vertical direction and have the same magnetic direction.

[0079] Specifically, when plug assembly 1 is inserted into receptacle trigger assembly 2, a press-fit contact is formed between plug pin 12 and conductive sheet 200. External force exerted on plug assembly 1 drives first magnetic element 4 above first damping layer 22. At this point, first, second, and third magnetic elements 4, arranged in descending order, lie on the same straight line, with the same magnetic orientation, attracting each other. Under the attraction of first magnetic element 4, second magnetic element 5 approaches first magnetic element 4, bringing conductive layer 23 into contact with conductive terminal 27, completing the circuit. Simultaneously, as the distance between first and second magnetic elements 4 and 5 decreases, the attraction increases, causing receptacle trigger assembly 2 and second magnetic element 5 to remain stationary, achieving self-locking.

[0080] When the plug assembly 1 is removed from the receptacle trigger assembly 2, an external force pulls the first magnetic element 4 away from the first damping layer 22. As the attraction between the first magnetic element 4 and the second magnetic element 5 decreases, the second magnetic element 5, attracted by the third magnetic element 6, moves to the second damping layer 25 until it stops, separating the conductive layer 23 from the first conductive terminal 27 and disconnecting the circuit. The second and third magnetic elements 5 and 6 attract each other and remain stationary, eliminating the resistance and inconvenience associated with traditional receptacles. This instantaneous power supply and disconnection significantly improves safety and convenience.

[0081] In one embodiment, the socket trigger assembly 2 further includes two conductive plates 200 disposed on both sides of the socket housing 26 , second wires 201 communicating with each conductive plate 200 , and second wiring terminals 202 connected to ends of each second wire 201 ;

[0082] When the plug assembly 1 is inserted into the socket trigger assembly 2; the upper surface of each socket shell 26 is provided with two plug holes for plugging in the plug pins 12, and the top part of each conductive sheet 200 is located inside the corresponding plug hole and is in press-fit contact with the side of the corresponding plug pin 12.

[0083] Example 1

[0084] like Figures 1 to 8 As shown, this embodiment provides a power connection structure based on magnetic triggering, including a plug assembly 1, a socket trigger assembly 2, a plug shell 11, a plug pin 12, a first magnetic element 4, a first magnetic element sealing plate 14, an upper sealing plate 21 of the socket shell, a second magnetic element 5, a third magnetic element 6, a first shock-absorbing layer 22, a conductive layer 23, an insulating layer 24, a second shock-absorbing layer 25, a socket shell 26, a first conductive terminal 27, a lower sealing plate 203 of the socket shell, a conductive sheet 200, a second wire 201, and a second terminal 202.

[0085] The first magnetic element 4 is fixed in the plug assembly 1 and sealed with the first magnetic element sealing plate 14. In the socket trigger assembly 2, the first shock-absorbing layer 22 is fixed under the sealing plate 21 on the socket shell and is closely connected to the first conductive terminal 27. The first conductive terminal 27 is close to the lower part of the first shock-absorbing layer 22. The surface of the second magnetic element 5 is sequentially attached with an insulating layer 24 and a conductive layer 23 from bottom to top. The second shock-absorbing layer 25 is located below the second magnetic element 5 and fixed to the bottom of the mounting hole on the socket shell 26. A movable gap is provided between the first conductive terminal 27 and the second shock-absorbing layer 25. The gap height is greater than the sum of the thickness of the second magnetic element 5, the insulating layer 24 and the conductive layer 23, and provides space for the second magnetic element 5 to move up and down. The third magnetic element 6 is located below the second shock-absorbing layer 25 and is fixed on the lower sealing plate 203 of the socket shell. The first wire 28 is used to connect the first conductive terminal 27 to the external circuit. The socket shell 26 is provided with a conductive sheet 200, which is connected to the external circuit through the second wire 201.

[0086] When the plug assembly 1 is inserted into the receptacle trigger assembly 2, the plug pin 12 and the conductive plate 200 press and contact, driving the first magnetic element 4 above the first damping layer 22 and toward the second magnetic element 5. At this point, the first, second, and third magnetic elements 4, arranged in descending order, are aligned with their centers on the same straight line and have the same magnetic orientation, attracting each other. When the attraction between the first and second magnetic elements 4 and 5 is greater than the attraction between the second and third magnetic elements 5 and 6, the second magnetic element 5 moves toward the first magnetic element 4 under the attraction of the first magnetic element 4, bringing the conductive layer 23 into contact with the first conductive terminal 27. This completes the circuit, with the plug pin 12 and the conductive plate 200 fully press and contact, and the circuit is on. At this point, the attraction between the first and second magnetic elements 4 and 5 is greater than the attraction between the second and third magnetic elements 5 and 6. The first and second magnetic elements 4 and 5 remain stationary and attract each other, achieving a self-locking function.

[0087] When the plug assembly 1 is pulled out of the socket trigger assembly 2, the plug assembly 1 is separated from the socket trigger assembly 2, the first magnetic element 4 moves away from the first shock-absorbing layer 22, and the second magnetic element 5 moves to the second shock-absorbing layer 25 under the suction force of the third magnetic element 6 until it stops, so that the conductive layer 23 is separated from the first conductive terminal 27, and the circuit is disconnected. At this time, the current of the conductive sheet 200 is interrupted, the circuit is not conductive, the plug pin 12 is completely separated from the conductive sheet 200, and the third magnetic element 6 and the second magnetic element 5 remain stationary and attract each other, thereby realizing the self-locking function.

[0088] Example 2

[0089] like Figures 9 to 17As shown, this embodiment provides a power connection structure based on magnetic triggering. Compared with Example 1, the main change in Example 2 is the addition of a plug trigger assembly follower 3. The plug trigger assembly follower 3 includes a plug trigger follower housing 300 and a third magnetic element 6. The third magnetic element 6 is fixed to the bottom of the plug trigger follower housing 300. The inner wall of the plug trigger follower housing 300 is provided with a conductive plate groove for accommodating the conductive plate 200. The first magnetic element sealing plate 14 of the plug assembly 1 and the second shock-absorbing layer 25 of the socket trigger assembly 2 are eliminated. The first magnetic element 4 is moved to the bottom of the sealing plate 21 on the socket housing and fixed there. The other structural functions remain unchanged.

[0090] Through this structural design, when the plug assembly 1 is inserted into the receptacle trigger assembly 2, the first magnetic element 4 is driven above the first damping layer 22 and toward the second magnetic element 5. The plug pin 12 pushes the plug trigger assembly follower 3 downward, causing the plug pin 12 to press and contact the conductive plate 200. At this point, the third magnetic element 6 moves away from the second magnetic element 5. The first, second, and third magnetic elements 4, 5, and 6 are arranged sequentially from top to bottom, with their centers aligned and magnetically directed, attracting each other. As the third magnetic element 6 moves away, when the attractive force between the first and second magnetic elements 4 and 5 becomes greater than the attractive force between the second and third magnetic elements 5 and 6, the second magnetic element 5, attracted by the first magnetic element 4, moves toward the first magnetic element 4, bringing the conductive layer 23 into contact with the first conductive terminal 27. This completes the circuit. Simultaneously, as the distance between the first and second magnetic elements 4 and 5 decreases, the attractive force increases, fully pressuring the plug pin 12 and the conductive plate 200, and conducting the circuit. At this time, the friction force of the pressed contact between the plug pin 12 and the conductive sheet 200 is greater than the sum of the attractive forces of the second magnetic element 5 and the third magnetic element 6 and the gravity of the plug assembly 1. The plug assembly 1, the socket trigger assembly 2 and the plug trigger assembly follower 3 remain stationary, realizing the self-locking function.

[0091] When the plug assembly 1 is pulled out of the socket trigger assembly 2, the plug assembly 1 is separated from the socket trigger assembly 2, and the third magnetic element 6 drives the plug trigger assembly follower 3 to move upward under the attraction of the second magnetic element 5. When the attraction between the third magnetic element 6 and the second magnetic element 5 is greater than the attraction between the first magnetic element 4 and the second magnetic element 5, the second magnetic element 5 moves to the lower cover plate 203 of the socket shell under the suction force of the third magnetic element 6 until it stops, so that the conductive layer 23 is separated from the first conductive terminal 27, and the circuit is disconnected. At this time, the current of the conductive sheet 200 is interrupted, the circuit is not conductive, the plug pin 12 is completely separated from the conductive sheet 200, the socket trigger assembly 2 and the plug trigger assembly follower 3 remain stationary, and the attraction between the third magnetic element 6 and the second magnetic element 5 is greater than the mutual attraction between the first magnetic element 4 and the second magnetic element 5, thereby realizing the self-locking function.

[0092] Example 3

[0093] like Figures 18 to 26 As shown, this embodiment provides a power connection structure based on magnetic triggering. Compared with Example 1, the main difference in Example 3 is the addition of a plug trigger assembly follower 3. The plug trigger assembly follower 3 includes a plug trigger follower housing 300 and a third magnetic element 6. The third magnetic element 6 is fixed to the bottom of the plug trigger follower housing 300. The inner wall of the plug trigger follower housing 300 is provided with a conductive sheet groove for accommodating the conductive sheet 200. The other structural functions remain unchanged.

[0094] Through this structural design, when the plug assembly 1 is inserted into the receptacle trigger assembly 2, the first magnetic element 4 is driven above the first damping layer 22 and toward the second magnetic element 5. The plug pin 12 pushes the plug trigger assembly follower 3 downward, causing the plug pin 12 to press and contact the conductive plate 200. At this time, the third magnetic element 6 moves away from the second magnetic element 5. The first magnetic element 4, the second magnetic element 5, and the third magnetic element 6 are arranged in order from top to bottom, with the centers of the three magnetic elements located on the same straight line and the same magnetic direction, attracting each other. As the third magnetic element 6 moves away, when the attraction between the first magnetic element 4 and the second magnetic element 5 is greater than the attraction between the second magnetic element 5 and the third magnetic element 6, the second magnetic element 5 moves toward the first magnetic element 4 under the attraction of the first magnetic element 4, causing the conductive layer 23 to contact the first conductive terminal 27, thus closing the circuit. At the same time, as the distance between the first magnetic element 4 and the second magnetic element 5 decreases, the attraction increases, and the plug pin 12 and the conductive plate 200 are fully pressed and contacted, thus completing the circuit. At this time, the attraction between the first magnetic element 4 and the second magnetic element 5 is greater than the attraction between the third magnetic element 6 and the second magnetic element 5, and the plug assembly 1, the socket trigger assembly 2 and the plug trigger assembly follower 3 remain stationary, achieving a self-locking function.

[0095] When the plug assembly 1 is pulled out of the socket trigger assembly 2, the plug assembly 1 is separated from the socket trigger assembly 2, the first magnetic element 4 moves away from the first shock-absorbing layer 22, the third magnetic element 6 and the second magnetic element 5 attract each other, driving the plug trigger assembly follower 3 to move upward, and the second magnetic element 5 moves to the lower cover plate 203 of the socket shell under the suction force of the third magnetic element 6 until it stops, so that the conductive layer 23 is separated from the first conductive terminal 27, and the circuit is disconnected. At this time, the current of the conductive sheet 200 is interrupted, the circuit is not conductive, the socket trigger assembly 2 and the plug trigger assembly follower 3 remain stationary, the third magnetic element 6 and the second magnetic element 5 attract each other, realizing the self-locking function.
