DETAILED DESCRIPTION

[0036] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0037] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0038] This embodiment provides a magnetic resonance device 1, see Figure 1 The magnetic resonance device 1 may include a body 100 and a connector 200, wherein the body 100 is provided with a connection socket 110. The connector 200 may be adapted to the connection socket 110, the connector 200 may be connected to the connection socket 110, and one end of the connector 200 away from the connection socket 110 may be connected to a power supply device, a control device, etc., to achieve current transmission, control signal transmission, etc.

[0039] In one embodiment, please also refer to Figure 1 as well as Figure 2 The connector 200 can be selectively inserted into the connection base 110 and electrically connected to the connection base 110. Further, the connection base 110 has an insertion port 111. The connector 200 has a plugging direction (eg Figure 2The plug-in direction may be the movable direction for the connector 200 to complete the connection with the connection base 110. The specific plug-in direction needs to be selected and set according to the structure of the connector 200 and the relative position relationship, and this embodiment does not limit it. The connector 200 can be inserted into the connection base 110 from the plug interface 111 along the plug-in direction to complete the electrical connection between the two. Exemplarily, the connector 200 and the connection base 110 may have a first connection part and a second connection part that are detachably connected. The first connection part may be a buckle, and the second connection part may be a slot. The arrangement of the buckle and the slot can achieve a stable connection between the connector 200 and the connection base 110, and prevent the connection base 110 from falling off due to dragging, crushing, etc. of the wiring harness 230.

[0040] In other embodiments, the connection method of the connector 200 and the connection base 110 can also be threaded connection, fastener locking, etc. Different connection methods are based on adapting to the application scenario while ensuring that the connector 200 and the connection base 110 are stably connected.

[0041] In another embodiment, the body 100 may also be configured with other types of connectors that are compatible with the connector 200. For example, see Figure 3 The connector 200 may be a male connector, that is, the connector 200 has a male pin. The body 100 may be configured with a female connector 300, that is, the female connector 300 has a female pin. The male pin and the female pin are arranged to cooperate with each other to achieve electrical connection between the two.

[0042] In this example, see Figure 4 as well as Figure 5 The connector 200 may include a housing 210 and a wiring harness 230, one end of the wiring harness 230 is disposed in the housing 210, and the other end extends from the housing 210. Further, the connector 200 may also include a connector 220, at least a portion of which is disposed in the housing 210, and the connector 220 is electrically connected to the wiring harness 230.

[0043] It is understandable that the connector 200 provided in this embodiment can also be applied to cable equipment, network equipment, industrial control equipment, and power transportation equipment, and this embodiment does not limit it. In addition, the connector 200 has different shapes or sizes under the premise of different application scenarios, so as to be conveniently adapted to different application requirements and adaptation objects.

[0044] The wiring harness 230 may be a coaxial wiring harness, an optical fiber, a DC wiring harness, or a combination thereof. For example, the wiring harness 230 may be a combination of a coaxial wiring harness and an optical fiber, which is not limited in this embodiment.

[0045] Specifically, the housing 210 may be a columnar structure, and further, the cross section of the housing 210 may be circular or elliptical, etc., so that the user can grasp the housing 210 directly. The housing 210 may be a metal housing, such as a stainless steel housing, and the housing 210 may have an electromagnetic shielding effect to avoid external electromagnetic interference.

[0046] Please continue reading Figure 5 The housing 210 may include a bottom housing 211 and a side housing 212, and the bottom housing 211 and the side housing 212 may be configured as an integral body. The side housing 212 is disposed around the edge of the bottom housing 211, and the bottom housing 211 and the side housing 212 form a receiving space 213, and the connector 220 is at least partially disposed in the receiving space 213. Further, the connector 220 is disposed in the receiving space 213, and the receiving space 213 has an opening 216, and at least a portion of the connector 220 may extend from the opening 216 and be used to be electrically connected to the connector 200. The housing 210 may be used to resist external impact to protect the connector 220 and improve the service life of the connector 220.

[0047] In one embodiment, the outer surface of the housing 210 may be provided with a flexible anti-skid portion, which can increase the friction of the outer surface, prevent the connector 200 from slipping out of the hand, and improve the safety of the connector 200.

[0048] The connector 220 can be installed in the housing 210, and the connector 220 can be insulated relative to the housing 210 to avoid affecting the normal use of the connector 220. The connector 220 has a plug-in direction (eg Figure 4 As shown in L2 in the figure, the connector 220 can be plugged into the connector base 110 along the plugging direction. Further, the opening 216 of the housing 210 can be opened in the housing 210, and one end of the connector 220 can extend from the opening 216 and be connected to the connector base 110 along the plugging direction.

[0049] In a more specific implementation, please also refer to Figure 5 as well as Figure 6 The connector 220 may include a guide ring 221, an insulating seat 222, and a plurality of pins 223. The insulating seat 222 is disposed in the accommodating space 213, the guide ring 221 is sleeved on the outer wall of the insulating seat 222, and the plurality of pins 223 are disposed on the insulating seat 222 and at least partially extend out of the insulating seat 222, and the pins 223 can be electrically connected to the wiring harness 230.

[0050] The plug pin 223 may be a PIN pin, and the PIN pin may be a conductive component used to complete the electrical signal in the connector 200. The plug pin 223 may be a columnar structure, and its cross section may be circular, rectangular, etc. The plug pin 223 may extend along the plugging direction to ensure that both ends of the plug pin 223 can be electrically connected to the wiring harness 230 and the connector 110, respectively, to achieve signal transmission or power transmission between the wiring harness 230 and the connector 110.

[0051] The insulating seat 222 can be made of materials such as polytetrafluoroethylene (PTFE) and nylon (PA). The insulating seat 222 can fix the pin 223. The insulating seat 222 can ensure that the pin 223 inside is insulated relative to the housing 210, thereby ensuring the safety of the connector 220. A portion of the insulating seat 222 extends out of the accommodating space 213, and a portion of the insulating seat 222 can be inserted into the connecting seat 110 to ensure that the pin 223 can be stably connected to the connecting seat 110.

[0052] The cross section of the insulating seat 222 may be circular, the structure of the insulating seat 222 may be cylindrical, and the pins 223 may extend along the axis of the cylinder. Further, the cross section of the housing 210 may be configured as a circle, and the mutually adapted shape settings may enable the housing 210 to accommodate a larger size of the insulating seat 222. As the size of the insulating seat 222 becomes larger, the number of the built-in pins 223 thereof is further increased, thereby improving the application scope of the connector 200. Moreover, under the premise that the housing 210 meets the maximum holding size, the insulating seat 222 with a cylindrical structure may accommodate more pins 223.

[0053] In another implementation, the cross-section of the insulating seat 222 may also be elliptical, rectangular, etc., which is not limited in this embodiment.

[0054] For more details, see Figure 7 The insulating seat 222 includes a first area 224, a second area 225 and a third area 226. The second area 225 surrounds the first area 224, and the third area 226 surrounds the second area 225. Exemplarily, the insulating seat 222 can be a cylinder, and the cross section of the insulating seat 222 is circular. The first area 224, the second area 225 and the third area 226 can be distributed radially. The insulating seat 222 is configured with multiple areas, and different areas can be configured with different types of pins 223. This configuration can make the design of the insulating seat 222 more standardized and can also reduce the difficulty of designing the pins 223.

[0055] In one embodiment, if Figure 7 As shown in Figure 7Only a schematic diagram of the structure of the insulating seat 222 with 30 pins 223 is shown. The number of pins 223 arranged in the first area 224 is 4, the number of pins 223 arranged in the second area 225 can be 10, and the number of pins 223 arranged in the third area 226 can be 16. This configuration is conducive to the standardization of the distribution of pins 223 inside the insulating seat 222, reducing the types of connectors 200. In addition, when the insulating seat 222 is a cylinder, the distribution of multiple pins 223 can also be configured to be symmetrical along the axis, which can ensure that the connector 200 can be inserted into the connection seat 110 in a variety of states, thereby improving the plug-in efficiency of the connector 200. With this structure as a reference, other embodiments can design and select other numbers of pins 223.

[0056] In other embodiments, the number of the pins 223 disposed in the first area 224 may be greater than or equal to 4, such as 4, 6, 8, etc., which is not limited in this embodiment. The number of the pins 223 disposed in the second area 225 may be greater than or equal to 10, such as 10, 14, 18, etc., which is not limited in this embodiment. The number of the pins 223 disposed in the third area 226 may be greater than or equal to 16, such as 16, 20, 24, etc., which is not limited in this embodiment.

[0057] It is understandable that the adapter of the insulating seat 222 cannot fully utilize all the pins 223. The unused pins 223 in this embodiment can be configured as insulating pins or removed to avoid short circuit or interference with the plugging of the connector 200. Exemplarily, the insulating seat 222 has 30 male pins, and the connecting seat 110 is only equipped with 20 female pins. In order to ensure the connection stability between the insulating seat 222 and the connecting seat 110, the redundant pins of the insulating seat 222 can be removed to avoid interference with the connection effect between the insulating seat 222 and the connecting seat 110.

[0058] Please review Figure 5 The guide ring 221 may be provided with a guide block 227, and the connecting seat 110 is correspondingly provided with a guide groove 112, and the guide block 227 is provided corresponding to the guide groove 112. The guide block 227 is embedded in the guide groove 112, which can ensure that the connector 220 and the connecting seat 110 cooperate with each other along the predetermined position and limit the freedom of the connector 220 to rotate around the plug-in direction. The guide ring 221 can make the insulating seat 222 and the pin 223 inside it corresponding to the connecting seat 110, avoid the misalignment of the pin 223 or the insulating seat 222, ensure that the connector 200 can be plugged in place, and improve the safety of the connector 200.

[0059] In one embodiment, the guide ring 221 can be configured as a metal material, and the guide ring 221 has certain wear resistance, strength, etc. The guide ring 221 can be inserted into the connector 200 along with the connector 220, and the guide ring 221 is arranged outside the connector 220. The guide ring 221 can avoid friction between the connector 220 and the connector 200, reduce the wear of the connector 220, and protect the connector 220 from external impact, etc., effectively improving the service life of the connector 220.

[0060] In this embodiment, please also refer to Figure 3 as well as Figure 5 The connector 200 further includes a snap-fitting portion 240, which cooperates with the slot of the connector base 110. The snap-fitting portion 240 is located between the connector 220 and the housing 210, and the snap-fitting portion 240 can selectively be embedded in the slot of the connector base 110 or withdraw from the slot of the connector base 110. When the snap-fitting portion 240 is embedded in the slot of the connector base 110, the freedom of the connector 220 in the plugging direction is limited, and the connector 200 can be locked in the connector base 110. When the snap-fitting portion 240 withdraws from the slot of the connector base 110, the restriction of the connector 220 in the plugging direction is released, and the connector 200 can be separated from the connector base 110. The snap-fitting portion 240 realizes the locking between the connector 200 and the connector base 110, prevents the connector 200 from falling off when being dragged by external force, and ensures the stability of the connector 200.

[0061] More specifically, the side shell 212 is provided with a card slot 214, which penetrates the housing 210, and the engaging portion 240 may include a card connection portion 241, an elastic member 242, a button 243 and a baffle 244. The button 243 corresponds to the card slot 214 and can be embedded in the card slot 214. The card slot 214 enables the button 243 to be set in the housing 210, and the user can press the button 243 through the card slot 214. The baffle 244 is set in the accommodating space 213, and the baffle 244 can isolate the card connection portion 241 and the elastic member 242 from the connector 220, and the baffle 244 has a protective effect. Among them, the baffle 244 can be configured as a metal baffle 244, which has the characteristics of high strength, etc., and further improves the protective effect. The elastic member 242 abuts between the baffle 244 and the button 243, and the card connection portion 241 connects the button 243 and extends out of the housing 210 along the plugging direction. The elastic member 242 deforms to generate elastic force, which drives the button 243 and the clamping part 241 to fit into the slot of the connector 110. The user can use the button 243 to drive the clamping part 241 out of the slot of the connector 110 to release the restriction of the connector 220 in the plugging direction.

[0062] In one embodiment, the number of the card slots of the engaging portion 240 and the connecting seat 110 can be set to at least two. Taking two sets of mutually cooperating engaging portions 240 and the card slots of the connecting seat 110 as an example, the card slots of the two connecting seats 110 can be symmetrically arranged, and the two engaging portions 240 can be correspondingly arranged in the card slots of the two connecting seats 110. The user can press from both sides of the connector 200 to ensure that the connector 200 is evenly stressed, thereby improving the use effect and service life of the connector 200.

[0063] See also Figure 5 For ease of understanding, the following content explains the working principle of the engaging portion 240:

[0064] Before the connector 200 is inserted into the connection base 110, the user can press the button 243, and the button 243 drives the clamping part 241 to exit the clamping slot of the connection base 110. At the same time, the button 243 can also drive the elastic member 242 to deform, so that the connector 200 can be smoothly inserted into the connection base 110. When the user releases the button 243, the deformed elastic member 242 can drive the button 243 and the clamping part 241 to return to their original state, that is, the clamping part 241 is embedded in the clamping slot of the connection base 110. When the connector 200 needs to be unplugged, the user can press the button 243 again, and the button 243 drives the clamping part 241 to exit the clamping slot of the connection base 110, so that the connector 200 can be smoothly unplugged from the connection base 110.

[0065] In one embodiment, please refer to Figure 5 The end of the clamping portion 241 close to the plugging direction may be configured with an inclined surface. When the user inserts the connector 200 into the connection seat 110, the inclined surface abuts against the connection seat 110. As the user continues to insert, the clamping portion 241 is driven and automatically embedded in the card slot of the connection seat 110, thereby preventing the clamping portion 241 from affecting the connection between the connector 200 and the connection seat 110. During the plugging process of the connector 200, the user can complete the plugging operation without pressing the button 243, thereby improving the plugging efficiency of the connector 200.

[0066] Preferably, the button 243 is provided with an anti-slip member, or the surface of the button 243 is subjected to an anti-slip treatment. Exemplarily, the anti-slip treatment may be provided with a plurality of protrusions on the surface of the button 243, the protrusions increase the surface friction of the button 243, and the protrusions are convenient for the user to press or plug and unplug, and also have a different touch, and the touch is different from the housing 210, so that the user can perform plug and unplug operations without looking at the connector 200.

[0067] In this example, see Figure 4One end of the wire harness 230 is electrically connected to the connector 220, and the other end can extend from the housing 210. The connection between the wire harness 230 and the connector 220 can be welding or fastener connection, etc., which is not limited by the present application. Further, one end of the wire harness 230 close to the connector 220 can be welded to the pin 223 of the connector 220 to ensure a stable connection between the wire harness 230 and the pin 223.

[0068] The housing 210 is provided with a through hole 215. Furthermore, the through hole 215 is provided in the bottom housing 211 or the side housing 212 so that the end of the wire harness 230 away from the connector 220 can extend from the housing 210, and the wire harness 230 can rotate relative to the housing 210. Figure 4 When subjected to external pulling force, the wire harness 230 is driven to rotate appropriately to avoid stress between the wire harness 230 and the connector 200. In addition, in a narrow space, the rotatable wire harness 230 has multiple extension directions, which enhances the adaptability of the connector 200 and improves the service life and adaptability of the connector 200.

[0069] In one embodiment, see Figure 4 as well as Figure 5 , through hole 215 can be formed in side shell 212, wire harness 230 extends out of through hole 215, and the aperture of through hole 215 can be larger than the outer diameter of wire harness 230, so that wire harness 230 can be movably arranged in through hole 215. A rotation gap is formed between wire harness 230 and the inner wall surrounding through hole 215, and wire harness 230 can realize rotation effect through the through hole 215 structure, and wire harness 230 can rotate around the plug-in direction. Exemplarily, the extension direction of wire harness 230 intersects with the plug-in direction, and further, the extension direction of wire harness 230 is perpendicular to the plug-in direction. Figure 4 As shown, the plugging direction of the connector 200 is as follows Figure 4 In the z direction, the extension direction of the wire harness 230 can be as follows Figure 4 In the x direction, the harness 230 can rotate around the plug-in direction, that is, the harness 230 can rotate around Figure 4 The x-direction rotation settings in .

[0070] In another embodiment, the through hole 215 can be provided in the bottom shell 211, and the wire harness 230 can also extend from the bottom shell 211. The wire harness 230 extends out of the through hole 215, and the distribution direction of the wire harness 230 can be parallel to the plug-in direction. The axis of the through hole 215 can be parallel to the plug-in direction, and can be configured according to the extension direction of the wire harness 230. The aperture of the through hole 215 can be larger than the outer diameter of the wire harness 230, and the wire harness 230 can swing along the plane where the plug-in direction is located. Exemplarily, the extension direction of the wire harness 230 is parallel to the plug-in direction, and further, the extension direction of the wire harness 230 is colinear with the plug-in direction. Figure 8As shown, the plugging direction of the connector 200 is as follows Figure 8 In the z direction, the extension direction of the wire harness 230 may be the same as Figure 8 In the direction opposite to the z direction in FIG. 1 , the wiring harness 230 can rotate around a direction perpendicular to the plugging direction, that is, the wiring harness 230 can rotate around Figure 8 The y-direction rotation setting in .

[0071] It is understandable that the angle between the extension angle of the wire harness 230 and the plugging direction can be 90° and 180°, that is, the extension angle of the wire harness 230 and the plugging direction are perpendicular or parallel to each other. The extension angle of the wire harness 230 is convenient for users to hold or grab. The wire harness 230 with multiple different extension angles is suitable for scenes with small space and limited opening space of the connector 110, so that the wire harness 230 has more layout methods and improves the use range of the connector 200.

[0072] For more details, please refer to Figure 5 The housing 210 may include a first housing 217 and a second housing 218. The first housing 217 and the second housing 218 are arranged opposite to each other and connected by a card pin 219. The connection by the card pin 219 makes the connection between the first housing 217 and the second housing 218 more stable. In addition, the first housing 217 and the second housing 218 may be connected by fastener connection, snap connection, etc. The first housing 217 and the second housing 218 enclose a housing space 213, and a through hole 215 is opened in the first housing 217 and the second housing 218. Exemplarily, the first housing 217 is provided with a first notch, and the second housing 218 is provided with a second notch. When the first housing 217 and the second housing 218 are connected to each other, the first notch and the second notch correspond to and form a through hole 215. Further, when the housing 210 is installed, the wiring harness 230 may be placed in the first notch or the second notch, and the second housing 218 or the first housing 217 is installed so that the wiring harness 230 can be installed in the through hole 215.

[0073] In another embodiment, the housing 210 may be integrally formed, and the wiring harness 230 may be installed in the through hole 215 by threading, thereby improving the structural stability of the housing 210 .

[0074] The side shell 212 can be configured to be arc-shaped, and the arc-shaped structure fits the palm of the user more closely, so that the user can take the connector 200 more easily. The through hole 215 is configured as a strip hole opened along the circumference of the side shell 212, and the wire harness 230 arranged in the through hole 215 can be slidably arranged along the circumference of the side shell 212. Furthermore, the plug-in direction can be parallel to the axial direction of the side shell 212, and the wire harness 230 can be rotated around the plug-in direction. The wire harness 230 has more arrangement methods to avoid the wire harness 230 interfering with the use effect of the connector 200.

[0075] In this embodiment, please also refer to Figure 4 as well as Figure 5 The connector 200 may also include a decorative piece 250. The decorative piece 250 may be made of metal, which is more wear-resistant and more beautiful. The decorative piece 250 may be rotatably disposed on the side shell 212 and cover the through hole 215. The decorative piece 250 may prevent the internal structure of the connector 200 from being exposed, so as to make the connector 200 more beautiful. In addition, the decorative piece 250 may separate the accommodating space 213 from the outside world, so as to prevent the internal components of the connector from falling off. The wiring harness 230 is fixed to the decorative piece 250. The decorative piece 250 may fix the wiring harness 230 to the side shell 212. The degree of freedom of the wiring harness 230 in the axial direction of the through hole 215 is limited, so as to ensure the safe use of the wiring harness 230.

[0076] Furthermore, the decorative member 250 can be rotatably arranged on the inner wall of the side shell 212, the outer surface of the decorative member 250 can be arranged in contact with the inner wall surrounding the through hole 215, the decorative member 250 can be arranged between the side shell 212 and the connector 200, and the decorative member 250 can be rotatably arranged along the circumferential direction of the side shell 212. The decorative member 250 can be rotatably arranged together with the wire harness 230, which can not only ensure the rotatable arrangement of the wire harness 230, but also make the connector 200 more beautiful.

[0077] In another embodiment, the decorative member 250 is rotatably disposed on the inner wall of the bottom shell 211. The decorative member 250 can ensure the rotatable setting of the wiring harness 230 and make the connector 200 more beautiful. This embodiment will not be described in detail.

[0078] For more details, please refer to Figure 4 The decorative member 250 may include a covering portion 251 and a limiting portion 252, the covering portion 251 and the limiting portion 252 are connected to each other, and the covering portion 251 is used to cover the through hole 215. The decorative member 250 also has a mounting hole that runs through the covering portion 251 and the limiting portion 252, and the wire harness 230 is inserted into the mounting hole. And there is an interference fit between the wire harness 230 and the mounting hole, so that the wire harness 230 can be fixed in the decorative member 250. The covering portion 251 is slidably disposed between the connector 220 and the housing 210, and the covering portion 251 can always cover the through hole 215 during the sliding process of the decorative member 250, thereby improving the aesthetics of the connector 200. The limiting portion 252 extends into the through hole 215, and the outer diameter of the limiting portion 252 is smaller than the aperture of the second through hole 215. The limiting portion 252 selectively abuts against or separates from the hole wall of the second through hole 215 during the sliding of the covering portion 251. The movable range of the limiting portion 252 is limited by the through hole 215 to limit the movable range of the decorative part 250 and the wiring harness 230, thereby preventing the decorative part 250 and the wiring harness 230 from being damaged due to excessive rotation.

[0079] Preferably, the shape of the covering portion 251 can be arranged to fit the inner wall of the housing 210 , so that the covering portion 251 can completely cover the through hole 215 , and the connector 200 has a more beautiful effect.

[0080] It is understandable that when the wire harness 230 extends from the bottom shell 211, the decorative member 250 can also be configured to be rotatably disposed on the inner wall of the bottom shell 211 to ensure the rotation of the wire harness 230 and make the connector 200 more beautiful.

[0081] If the rotation angle of the wire harness 230 is too large, the wire harness 230 may be entangled and the wire harness 230 may be easily damaged. If the rotation angle of the wire harness 230 is too small, the rotation effect of the wire harness 230 is poor, and the extension range of the wire tail is too small, which affects the adaptability and service life of the connector 200. The wire harness 230 has an appropriate rotation angle, which can ensure the safety of the use of the wire harness 230 and improve the adaptability and service life of the connector 200. Fig. 9 as well as Fig.10 , Fig. 9 shows a schematic structural diagram of the wiring harness 230 in a first state, Fig.10 FIG. 2 shows a schematic diagram of the structure of the wiring harness 230 in the second state. In this embodiment, the rotation angle (eg, Fig.10 The angle a in the figure can be 0-36°, for example, the rotation angle can be 0, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 36°, etc., which is not specifically limited in this embodiment. In some other embodiments, the rotation angle of the wiring harness 230 around the plugging direction can also be other values, which is not limited in this embodiment.

[0082] The wire harness 230 is rotated to one end of the through hole 215 (eg Fig. 9 As shown), the wire harness 230 takes this end as the initial position and rotates around the plug-in direction, and the angle formed between the current position and the initial position of the wire harness 230 is the rotation angle.

[0083] In the connector 200 provided in the embodiment of the present application, one end of the wire harness 230 is disposed in the accommodating space 213, and the wire harness 230 can be electrically connected to other components or devices. When the connector 200 is plugged into other connection sockets or connectors, the wire harness 230 can be electrically connected to other connection sockets or connectors, and the wire harness 230 can rotate relative to the housing 210. The rotating wire harness 230 can avoid entanglement or twisting, facilitate the routing of the wire harness 230, and help extend the service life of the wire harness 230.

[0084] When the magnetic resonance device 1 using the connector 200 moves, the harness is forced to drive the connector 200 to rotate. The harness 230 can rotate according to the wiring requirements to avoid bending of the harness 230 during wiring, thereby ensuring the safety of the magnetic resonance device 1.

[0085] The above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various implementation modes of the present application, and should all be included in the protection scope of the present application.
