Description

Technical Field

[0001] The present invention relates to the field of power connection technology, and more specifically to the field of power connection structure technology based on magnetic force triggering. Widely used in power connection of electronic devices, such as mobile phones, laptops, etc., the magnetic force triggered power connection structure effectively improves the safety and connection stability of the power connection. Background Art

[0002] The power connection structure is a device used to control the on and off 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 requirements 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 have the problem of mechanical wear, which leads to a decrease in the reliability of the connector after long-term use and may cause safety hazards.

[0004] In addition, the physical contact characteristics of traditional mechanical power connection devices make their response speed slow, limiting their performance in application scenarios that require fast response. Traditional power connection structures mostly use mechanical control to turn the power on and off. Although this design is simple, it has the following shortcomings:

[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. There are safety hazards of leakage: In modern electronic devices, the safety and reliability of power connections are crucial. The wires inside traditional sockets are usually energized and exposed. When there is contact with conductive media, it is easy to cause safety hazards such as accidental electric shock.

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

[0008] The purpose of the present invention is 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. The present invention provides a power connection structure based on magnetic triggering. In order to achieve the above purpose, the present invention specifically adopts the following technical solutions:

[0009] The present invention provides a power connection structure based on magnetic triggering, comprising a socket trigger component and a plug component plugged into the socket trigger component. When the socket trigger component and the plug component are not plugged in, the circuit in the socket trigger component is disconnected. When the socket trigger component and the plug component are plugged in, the circuit in the socket trigger component is connected.

[0010] 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.

[0011] In one embodiment, a first mounting hole for accommodating the first magnetic element is disposed 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 disposed at the opening of the first mounting hole.

[0012] In one embodiment, the socket trigger assembly includes a socket shell and a magnetic conduction assembly arranged in the socket shell; a mounting through hole for mounting the magnetic conduction assembly and extending through the socket shell from top to bottom is arranged in the socket shell, and an upper sealing plate of the socket shell and a lower sealing plate of the socket shell for sealing the mounting through hole are arranged at both upper and lower ends of the socket shell;

[0013] The magnetic conduction 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;

[0014] The first shock-absorbing layer and the first conductive terminal are fixed in an up-and-down manner 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 up-and-down manner and then slidably arranged in the gap. The gap height 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 first conductive terminal is disconnected in the middle, and the conductive layer connects the disconnected portion of the first conductive terminal to achieve conduction of the first conductive terminal. After the conductive layer leaves the middle of the first conductive terminal, the first conductive terminal is disconnected.

[0015] The third magnetic element is located below the second shock absorbing layer in the socket housing.

[0016] 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.

[0017] 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.

[0018] 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. Under the action of external force, the plug assembly drives the first magnetic element to the top of the first shock-absorbing layer. At this time, the first magnetic element, the second magnetic element, and the third magnetic element are arranged in sequence from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction and attracting each other. The second magnetic element approaches the first magnetic element under the attraction of the first magnetic element, so that the conductive layer contacts the conductive terminal, the circuit is closed, and the circuit is turned on. At the same time, as the distance between the first magnetic element and the second magnetic element decreases, the attraction increases, and the socket trigger assembly and the second magnetic element remain stationary, achieving self-locking.

[0019] When the plug assembly is pulled out of the socket trigger assembly, the plug assembly moves the first magnetic element away from the first damping layer under the action of external force. At this time, as the suction between the first magnetic element and the second magnetic element decreases, the second magnetic element moves to the second damping layer under the suction of the third magnetic element until it stops, so that the conductive layer is separated from the first conductive terminal. At this time, the circuit is disconnected and the circuit is not conducting. The second magnetic element and the third magnetic element attract each other and remain stationary. The resistance and inconvenience caused by pulling the traditional socket are avoided. This feature of instant power transmission and disconnection greatly improves the safety and convenience of use.

[0020] In one embodiment, the socket trigger assembly further includes two conductive sheets arranged on both sides of the socket housing, second wires connected to the conductive sheets, and second wiring terminals connected to the ends of the second wires;

[0021] 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 the plug pins, and the top parts of the two conductive sheets are located inside the corresponding plugging holes and are pressed and contacted with the side surfaces of the corresponding plug pins.

[0022] Specifically, this solution has the following advantages:

[0023] Stability: The magnetic connection relies on a strong magnetic force to maintain close contact between the plug and the socket, and a pressed contact is formed between the plug pin and the conductive sheet, ensuring that the connection is stable and reliable even when the device moves or vibrates, and is not easy to disconnect; Durability: The wear of this structure only exists in the pressed contact between the plug pin and the conductive sheet during the plug-in process, and does not affect the conductive performance, so that the design has high durability and reliability, ensuring a stable connection during long-term use, and because the wear of the magnetic connector is greatly reduced, this makes the connector life longer and reduces the unstable connection caused by wear. Finally, the metal contacts in the present invention can be isolated from the outside, thereby avoiding the influence of physical and chemical changes such as oxidation or corrosion on the contact quality.

[0024] 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.

[0025] In one embodiment, it also includes a plug trigger assembly follower, 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, 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.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. In contrast, the working principle of the magnetically triggered power connection structure is to achieve the conduction and disconnection of the circuit through the change of the magnetic field. The electrical connection with the conductive sheet is achieved through the circuit layout, and this structure remains disconnected when not triggered. This design effectively prevents the conduction of the circuit when it is not connected, reduces the risk of electric shock, and ensures the safety of the user.

[0028] 2. The circuit closing and disconnection in this structure is carried out in a completely sealed and insulated space, which is completely waterproof and dustproof.

[0029] 3. Compared with the traditional mechanical structure, the performance of the mechanical power connection of the structure of the present invention 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 mechanical wear and slow response speed make it prone to failure after long-term use, reduce its reliability, and cause safety hazards. The present structure utilizes 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 all 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.

[0030] 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 can have the function of circuit data transmission.

[0031] 5. The position of the conductive sheet and the contact position and shape of the plug pins can be changed arbitrarily according to specific design requirements, aiming to provide greater flexibility and adaptability. The size and configuration of the power connection structure can be adjusted according to actual usage requirements to meet the power requirements of different devices and scenarios.

[0032] 6. The power connection structure shown in the present invention is a dual-plug mode, but it can also be applied to the neutral and live wire ports of three plugs 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 sheets, at least one of which maintains a circuit disconnected state when the structure is not triggered when the external power is connected, and the first conductive terminal, the first wire and the first wiring terminal of the power connection component are each composed of two parts, and the electrical connection with the conductive sheet is achieved through the circuit layout to ensure that the conductive sheet serving as the live wire remains voltage-free when the structure is not triggered. The first conductive terminal, the first wire and the first wiring terminal of the component can be further configured to consist of four parts, and the electrical connection with the conductive sheet is achieved through the circuit layout to ensure that the two conductive sheets remain current-free when the structure is not triggered).

[0064] In order to make the technical problems, technical solutions and technical effects of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0065] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0066] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0067] 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 inventive product is usually placed when used. 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, and therefore cannot be understood as a limitation on the present invention.

[0068] The present invention 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 inside the socket trigger component 2 is disconnected. When the socket trigger component 2 and the plug component 1 are plugged in, the circuit inside the socket trigger component 2 is connected.

[0069] 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 .

[0070] In one embodiment, a first mounting hole for accommodating the first magnetic element 4 is disposed at the bottom of the plug housing 11 , the first mounting hole is located between two plug pins 12 , and a first magnetic element sealing plate 14 is disposed at the opening of the first mounting hole.

[0071] In one embodiment, the socket trigger assembly 2 includes a socket housing 26 and a magnetic conduction assembly disposed in the socket housing 26; a mounting through hole for mounting the magnetic conduction assembly and extending through the socket housing 26 is disposed in the socket housing 26, and an upper socket housing sealing plate 21 and a lower socket housing sealing plate 203 for sealing the mounting through hole are disposed at both upper and lower ends of the socket housing 26;

[0072] The magnetic conductive component 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 conductive wire 28 and a first connecting terminal 29;

[0073] The first shock-absorbing layer 22 and the first conductive terminal 27 are fixed in an up-and-down 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 up-and-down manner and then slidably arranged in the gap. The gap height 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 is the 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 wiring 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 realize the connection or disconnection of the first conductive terminal 27.

[0074] The third magnetic element 6 is located below the second shock absorbing layer 25 in the socket housing 26 .

[0075] 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 effect, so that the plug assembly 1 and the socket trigger assembly 2 are tightly connected to avoid loosening.

[0076] 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.

[0077] Specifically, when the plug assembly 1 is inserted into the socket trigger assembly 2, a press-fit contact is formed between the plug pin 12 and the conductive sheet 200. Under the action of external force, the plug assembly 1 drives the first magnetic element 4 to the top of the first shock-absorbing layer 22. At this time, the first magnetic element 4, the second magnetic element 5, and the third magnetic element 6 are arranged from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction and attracting each other. The second magnetic element 5 approaches the first magnetic element 4 under the attraction of the first magnetic element 4, so that the conductive layer 23 contacts the conductive terminal 27, and the circuit is turned on. 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 socket trigger assembly 2 and the second magnetic element 5 remain stationary, achieving self-locking.

[0078] When the plug assembly 1 is pulled out of the socket trigger assembly 2, the plug assembly 1 moves the first magnetic element 4 away from the first shock-absorbing layer 22 under the action of external force. At this time, as the suction between the first magnetic element 4 and the second magnetic element 5 decreases, the second magnetic element 5 moves to the second shock-absorbing layer 25 under the suction 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. The second magnetic element 5 and the third magnetic element 6 attract each other and remain stationary. The resistance and inconvenience caused by pulling the traditional socket are avoided. This feature of instant power transmission and disconnection greatly improves the safety and convenience of use.

[0079] In one embodiment, the socket trigger assembly 2 further includes two conductive sheets 200 disposed on both sides of the socket housing 26, second wires 201 communicating with each conductive sheet 200, and second wiring terminals 202 connected to the ends of each second wire 201;

[0080] 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 plugging holes for plugging the plug pins 12, and the top portion of each conductive sheet 200 is located inside the corresponding plugging hole and is in press-fit contact with the side of the corresponding plug pin 12.

[0081] Example 1

[0082] 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 a 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 a socket shell, a conductive sheet 200, a second wire 201, and a second terminal 202.

[0083] 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 with 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 attached with the insulating layer 24 and the conductive layer 23 from bottom to top in sequence. 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. An active 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 and 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 with the external circuit. The socket shell 26 is provided with a conductive sheet 200, and the conductive sheet 200 is connected to the external circuit through the second wire 201.

[0084] When the plug assembly 1 is inserted into the socket trigger assembly 2, the plug pin 12 and the conductive sheet 200 are pressed and contacted, and the first magnetic element 4 is driven to the top of the first shock-absorbing layer 22 and close to the second magnetic element 5. At this time, the first magnetic element 4, the second magnetic element 5, and the third magnetic element 6 are arranged from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction, and attract each other. 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 approaches the first magnetic element 4 under the attraction of the first magnetic element 4, so that the conductive layer 23 contacts the first conductive terminal 27. At this time, the circuit is closed, the plug pin 12 and the conductive sheet 200 are completely pressed and contacted, and the circuit is turned on. At this time, 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 first magnetic element 4 and the second magnetic element 5 remain stationary and attract each other to achieve a self-locking function.

[0085] 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 is 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 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.

[0086] Example 2

[0087] like Figures 9 to 17As shown, this embodiment provides a power connection structure based on magnetic force triggering. Compared with the embodiment 1, the main change of the embodiment 2 is that a plug trigger assembly follower 3 is added. 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 first magnetic element sealing plate 14 of the plug assembly 1 and the second shock absorbing layer 25 in the socket trigger assembly 2 are cancelled, and the first magnetic element 4 is moved to the lower part of the sealing plate 21 on the socket housing and fixed, and other structural functions remain unchanged.

[0088] Through the design of this structure, when the plug assembly 1 is inserted into the socket trigger assembly 2, the first magnetic element 4 is driven to the top of the first damping layer 22 and close to the second magnetic element 5, and the plug pin 12 pushes the plug trigger assembly follower 3 to move downward so that the plug pin 12 and the conductive sheet 200 are pressed and contacted. At this time, the third magnetic element 6 is 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 sequence from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction, and attract 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 approaches the first magnetic element 4 under the attraction of the first magnetic element 4, so that the conductive layer 23 contacts the first conductive terminal 27, and the circuit is closed. At the same time, as the distance between the first magnetic element 4 and the second magnetic element 5 decreases, the attraction increases, the plug pin 12 and the conductive sheet 200 are completely pressed and contacted, and the circuit is turned on. 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 attraction of the second magnetic element 5 and the third magnetic element 6 and the gravity of the plug assembly 1, and the plug assembly 1, the socket trigger assembly 2 and the plug trigger assembly follower 3 remain stationary to achieve a self-locking function.

[0089] 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 sealing 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.

[0090] Example 3

[0091] like Figures 18 to 26 As shown, this embodiment provides a power connection structure based on magnetic force triggering. Compared with the embodiment 1, the main change of the embodiment 3 is that the plug trigger assembly follower 3 is added. 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. Other structural functions remain unchanged.

[0092] Through the design of this structure, when the plug assembly 1 is inserted into the socket trigger assembly 2, the first magnetic element 4 is driven to the top of the first damping layer 22 and close to the second magnetic element 5, and the plug pin 12 pushes the plug trigger assembly follower 3 to move downward, so that the plug pin 12 and the conductive sheet 200 are pressed and contacted. At this time, the third magnetic element 6 is away from the second magnetic element 5, and the first magnetic element 4, the second magnetic element 5, and the third magnetic element 6 are arranged in sequence from top to bottom, and the centers of the three magnetic elements are located on the same straight line, with the same magnetic direction, and attract 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 approaches the first magnetic element 4 under the attraction of the first magnetic element 4, so that the conductive layer 23 contacts the first conductive terminal 27, and the circuit is closed. At the same time, as the distance between the first magnetic element 4 and the second magnetic element 5 decreases, the attraction increases, the plug pin 12 and the conductive sheet 200 are completely pressed and contacted, and the circuit is turned on. 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.

[0093] 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 is 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 sealing 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, and the self-locking function is realized.
