Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly to a coil plugging module and a magnetic resonance imaging device. Background Art

[0002] With the continuous development of technology, magnetic resonance imaging technology has become one of the important means of modern medical clinical diagnosis, which has the advantages of high tissue density contrast, arbitrary azimuth layer imaging, and no ionizing radiation. In a magnetic resonance imaging device, it is usually necessary to electrically conduct between a magnetic resonance coil and a control system through a plug and a socket to transmit radio frequency signals. In the related art, if it is necessary to separate the plug and the socket in a connected state, the operation is relatively troublesome and the separation efficiency is low. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a coil plugging module and a magnetic resonance imaging device, which are more convenient and faster to operate when separating the plug and the socket in a connected state.

[0004] A coil plugging module is applied to a magnetic resonance imaging device, and the coil plugging module includes:

[0005] A socket, including a socket housing, a socket connector, and a first elastic member, the socket connector is connected to the socket housing; and

[0006] A plug, including a plug connector and a locking assembly connected thereto; wherein, the locking assembly includes a pressing plate and a locking member connected to the pressing plate;

[0007] When the plug is plugged into the socket, the locking member is locked to the socket housing, the plug connector contacts the socket connector, and the first elastic member is compressed by the pressing plate and abuts against the socket housing.

[0008] In some embodiments, one of the socket housing and the locking member includes a clamping block, and the other includes a clamping groove. When the plug is plugged into the socket, the clamping block is snapped into the clamping groove.

[0009] In some embodiments, the locking assembly further includes a button, the button is connected to the locking member, and the button is configured to be operably pressed to drive the locking member to rotate so that the clamping block disengages from the clamping groove.

[0010] In some embodiments, the locking assembly includes an elastic mechanism, the locking member, the button, and the pressing plate are arranged at intervals in sequence, and the locking member and the button are connected to the pressing plate through the elastic mechanism so that the button is movably connected to the locking member.

[0011] In some embodiments, the elastic mechanism includes a second elastic member and a third elastic member. The second elastic member abuts between the button and the pressing plate, and the third elastic member abuts between the locking member and the pressing plate.

[0012] In some embodiments, the plug includes two sets of the locking assemblies. The locking member in one set of the locking assemblies has a first connecting arm, and the locking member in the other set of the locking assemblies has a second connecting arm. The first connecting arm and the second connecting arm engage with each other.

[0013] In some embodiments, the locking member in each set of the locking assemblies includes the first connecting arm and the second connecting arm. The first connecting arm in each set of the locking assemblies engages with the second connecting arm in the other set of the locking assemblies.

[0014] In some embodiments, the plug includes a plug housing and a protective member. A part of the button protrudes outward from the outer wall of the plug housing, and the protective member is disposed on the plug housing around the button.

[0015] In some embodiments, the socket includes a top block. When the plug is inserted into the socket, one end of the first elastic member abuts against the top block, and the other end abuts against the socket housing. The pressing plate compresses the first elastic member through the top block.

[0016] A magnetic resonance imaging device includes the above-mentioned coil plugging module, and further includes a magnetic resonance coil and a control system. One of the magnetic resonance coil and the control system is connected to the socket, and the other is connected to the plug.

[0017] For the above-mentioned coil plugging module and magnetic resonance imaging device, when the plug is inserted into the socket, the plug connector contacts the socket connector to achieve electrical connection therebetween, thereby realizing electrical conduction between the magnetic resonance coil and the control system. At the same time, the locking member is locked to the socket housing so that the plug and the socket maintain the current inserted state and will not separate from each other to cause the electrical connection to be disconnected. Since the first elastic member is compressed by the pressing plate and abuts against the socket housing, that is, the first elastic member is in a compressed deformation state. Then, when the locking member is operated so that it is no longer locked to the socket housing, the first elastic member can push the pressing plate to move in the reverse direction through its own resilience, and further separate the plug and the socket. It can be seen that if you want to separate the plug and the socket in the connected state, you only need to operate the locking member so that it is no longer locked to the socket housing, and then the first elastic member can provide assistance to quickly and automatically separate the plug and the socket, without the operator manually disassembling the two, and the operation is more convenient and fast.

[0040] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown in FIGS.

[0041] In the coil plugging module in the above embodiments, when the plug 200 is plugged into the socket 100, the plug connector 210 and the socket connector 110 are in contact to achieve electrical connection therebetween, thereby realizing electrical conduction between the magnetic resonance coil and the control system. At the same time, the locking member 220 is locked to the socket housing 130 to keep the plug 200 and the socket 100 in the current plugged state and prevent them from separating from each other and causing the electrical connection to be disconnected. Since the first elastic member 121 is compressed by the pressing plate 251 and abuts against the socket housing 130, that is, the first elastic member 121 is in a compressed deformation state, when the locking member 220 is operated so that it is no longer locked to the socket housing 130, the first elastic member 121 can push the pressing plate 251 to move in the reverse direction through its own resilience, thereby separating the plug 200 and the socket 100. It can be seen that if it is necessary to separate the plug 200 and the socket 100 in the connected state, only the locking member 220 needs to be operated so that it is no longer locked to the socket housing 130, and then the first elastic member 121 can provide assistance to quickly and automatically separate the plug 200 and the socket 100 without the operator manually disassembling the two, and the operation is more convenient and fast.

[0042] Specifically, the locking member 220 has a locking position locked to the socket housing 130 and an unlocking position unlocked from the socket housing 130. When the plug 200 is plugged into the socket 100, the locking member 220 is located at the locking position. The locking member 220 is configured to be operably moved. When it reaches the unlocking position from the locking position, the first elastic member 121 pushes the pressing plate 251 through its own resilience, thereby quickly and automatically separating the plug 200 and the socket 100.

[0043] Refer to Figures 4 to 6, in some embodiments, the plug 200 includes a plug housing 260, the plug housing 260 includes an abutting block 261, or the plug housing 260 and the abutting block 261 are fixedly connected. The abutting block 261 is fixedly connected to the pressing plate 251, and the pressing plate 251 is fixedly connected to the plug housing 260. The socket 100 has an open cavity, and the whole plug 200 is inserted into the cavity. When the plug 200 is just inserted, the plug connector 210 and the socket connector 110 are not in contact yet, and there is a certain distance between them. As the plug 200 is inserted, the abutting block 261 will press down the first elastic member 121, deforming and compressing it. When the plug 200 is inserted to a certain depth and the plug connector 210 and the socket connector 110 are in contact, it means that the plug 200 has been inserted in place. At this time, as long as the locking member 220 reaches the locking position, the plug 200 and the socket 100 can be locked to prevent the plug 200 from withdrawing from the socket 100. When it is necessary to separate the plug 200 and the socket 100, first operate the locking member 220 to make it reach the unlocking position, that is, release the position locking of the plug 200 and the socket 100. The first elastic member 121 has a tendency to stretch and recover. When it stretches and recovers, it will push the abutting block 261, and then push the plug 200 out of the socket 100.

[0044] In some embodiments, when the plug 200 is plugged into the socket 100, the plug connector 210 and the socket connector 110 are plugged and matched to achieve electrical connection between the two. In other embodiments, when the plug 200 is plugged into the socket 100, the plug connector 210 and the socket connector 110 are abutted to achieve electrical connection between the two.

[0045] Refer to Figure 3 、 Figure 5 And Figure 6 , in some embodiments, one of the socket housing 130 and the locking member 220 includes a clamping block 2211, and the other includes a clamping groove 131; when the plug 200 is plugged into the socket 100, the clamping block 2211 is snapped into the clamping groove 131.

[0046] Specifically, when the locking member 220 is in the locking position, the clamping block 2211 is snapped into the clamping groove 131; when the locking member 220 is in the unlocking position, the clamping block 2211 withdraws from the clamping groove 131. In the embodiment shown in the drawings, the socket housing 130 includes the clamping groove 131, and the locking member 220 includes the clamping block 2211. Further, the clamping groove 131 is formed on the inner side wall of the socket housing 130. The shapes and sizes of the clamping block 2211 and the clamping groove 131 can be selected from any specifications in the prior art, as long as their shapes and sizes are adapted to achieve clamping. In other embodiments, the positions of the clamping block 2211 and the clamping groove 131 can also be interchanged, that is, the socket housing 130 includes the clamping block 2211, and the locking member 220 includes the clamping groove 131.

[0047] In the embodiment shown in the drawings, the direction in which the latch 2211 engages or disengages from the slot 131 is perpendicular to the direction in which the plug 200 is inserted into or withdrawn from the socket 100. In other embodiments, the direction in which the latch 2211 engages or disengages from the slot 131 may also be parallel to the direction in which the plug 200 is inserted into or withdrawn from the socket 100.

[0048] Referring to Figures 5 to 7 , in some embodiments, the locking assembly includes a button 230. The button 230 is connected to the locking member 220 and is configured to be operably pressed to disengage the latch 2211 from the slot 131 by driving the locking member 220 to rotate.

[0049] Specifically, the locking member 220 includes a rod portion 221 and a rotating shaft 222 that are connected to each other. The aforementioned latch 2211 is formed at one end of the rod portion 221 facing away from the rotating shaft 222. An inner wall of the plug housing 260 is provided with a rotating shaft groove 262. The rotating shaft 222 is installed in the rotating shaft groove 262 and can rotate within the rotating shaft groove 262. When the button 230 is pressed, the rod portion 221 will be pushed, thereby driving the entire locking member 220 to rotate inwardly toward the plug housing 260 around the rotating shaft 222, causing the latch 2211 to withdraw from the slot 131, and the locking member 220 reaches the unlocked position.

[0050] In other embodiments, the locking member 220 can also be driven to move from the locked position to the unlocked position by pressing the button 230.

[0051] Referring to Figure 1 and Figure 13 , in other embodiments, the button 230 can also be replaced with a push button 280. The push button 280 is pushed along the insertion or withdrawal direction of the plug 200 and the socket 100 to achieve the switching of the locking member 220 between the locked position and the unlocked position.

[0052] Referring to Figure 3 , Figure 5 , Figure 6 and Figure 8 , in some embodiments, the plug 200 includes an elastic mechanism 240. The locking member 220, the button 230, and the pressing plate 251 are arranged at intervals in sequence, and the locking member 220 and the button 230 are connected to the pressing plate 251 through the elastic mechanism 240, so that the button 230 is movably connected to the locking member 220.

[0053] Specifically, the elastic mechanism 240 drives the locking member 220 to rotate and reset to the locked position through its own resilience. When the button 230 is not pressed, the locking member 220 is in the locked position, and the latch 2211 extends out of the plug housing 260 and is exposed ( Figure 3When the plug 200 needs to be inserted into the socket 100, first press the button 230 against the elastic force of the elastic mechanism 240 to rotate the locking member 220 to the unlocking position, and the latch 2211 retracts into the plug housing 260 to prevent the exposed latch 2211 from interfering with the smooth insertion of the plug 200. At this time, the elastic mechanism 240 is compressed and deformed. When the plug 200 is inserted into the socket 100 to a certain depth, the plug connector 210 and the socket connector 110 are in contact, and the latch 2211 just reaches the entrance of the slot 131. At this time, release the button 230, and the elastic mechanism 240 stretches and returns, which will push the locking member 220 to rotate to the locking position, and the latch 2211 is snapped into the slot 131 to realize the locking of the plug 200 and the socket 100.

[0054] Refer to Figures 5 to 8 , in some embodiments, the elastic mechanism 240 includes a second elastic member 241 and a third elastic member 242. The second elastic member 241 abuts between the button 230 and the pressing plate 251, and the third elastic member 242 abuts between the locking member 220 and the pressing plate 251.

[0055] The button 230 pressed to a preset degree abuts against the locking member 220 and drives the locking member 220 to rotate. The third elastic member 242 drives the locking member 220 to reset through its own resilience, and the second elastic member 241 drives the button 230 to reset through its own resilience.

[0056] Specifically, the pressing plate 251 is located on the side of the locking member 220 away from the button 230, and the button 230 is inserted into the pressing plate 251 along its own pressing direction. Further, a convex post 252 protrudes from the side of the pressing plate 251 facing the locking member 220. The button 230 has a button shaft 231, and the button shaft 231 is inserted into the convex post 252 to guide the movement of the button 230. The second elastic member 241 is sleeved outside the convex post 252, and both ends of the second elastic member 241 are respectively abutted against the button 230 and the pressing plate 251. Both ends of the third elastic member 242 are respectively abutted against the locking member 220 and the pressing plate 251. A through hole 225 is provided on the locking member 220 for accommodating the second elastic member 241 and the third elastic member 242. The button 230 and the locking member 220 are not fixedly connected. Before the button 230 is pressed, the two are arranged at intervals, and there is a certain gap between them. When the button 230 is pressed, the button 230 will gradually approach the locking member 220 until it abuts against the rod portion 221 of the locking member 220. When the button 230 abuts against the rod portion 221, when the button 230 is continuously pressed, it will push the rod portion 221 to rotate inwardly towards the plug housing 260 around the rotation shaft 222, so that the latch 2211 exits the card slot 131, and the locking member 220 reaches the unlocking position. During the above process of pressing the button 230, both the second elastic member 241 and the third elastic member 242 are compressed and deformed. When the button 230 is released, the third elastic member 242 stretches and returns, pushing the locking member 220 to reset. At the same time, the second elastic member 241 stretches and returns, pushing the button 230 to reset.

[0057] It can be understood that the action of the locking member 220 switching between the unlocking position and the locking position is rotation, and the pressing and resetting actions of the button 230 are movement. In the above embodiment, the button 230 is movably connected to the locking member 220, and elastic members for resetting are respectively provided for the two. At the same time, the movement of the button 230 is guided by inserting the button shaft 231 into the convex post 252, so that the pressing and resetting of the button 230 will not be affected by the rotation of the locking member 220, that is, the button 230 always maintains the movement mode of moving, and will not rotate due to the rotation of the locking member 220, resulting in the button 230 itself being skewed, and the operation experience will be better.

[0058] Of course, in other embodiments, if the above factors are not considered, the button 230 and the locking member 220 can also be fixedly connected, and any one of the second elastic member 241 and the third elastic member 242 can be removed. At this time, as long as the button 230 is pressed, the locking member 220 will immediately rotate.

[0059] Refer to Figure 5 、 Figure 6 And Figure 12, in some embodiments, the plug 200 includes two sets of locking components. The locking member 220 in one set of locking components has a first connecting arm 223, and the locking member 220 in the other set of locking components has a second connecting arm 224. The first connecting arm 223 and the second connecting arm 224 are engaged with each other.

[0060] Specifically, there are two sets of the button 230, the locking member 220, the elastic mechanism 240, etc. When any one set of the buttons 230 is pressed, the locking members 220 in the two sets of locking components both rotate from the locked position to the unlocked position. Components such as the locking member 220, the button 230, the elastic mechanism 240, the pressing plate 251, and the abutting block 261 are all provided in a matching manner. The two sets of locking components are symmetrically arranged on both sides of the plug housing 260, and the structures of the components in each set are the same as those in the foregoing embodiments. Correspondingly, clamping grooves 131 are provided on the two opposite inner side walls of the socket housing 130, and there are also two sets of the first elastic members 121 correspondingly. When the plug 200 is inserted into the socket 100, the clamping blocks 2211 in each set of locking members 220 are all clamped into the corresponding clamping grooves 131, and each set of the first elastic members 121 is compressed and abuts against the corresponding abutting block 261.

[0061] By providing two sets of locking components, the stability after the plug 200 is inserted into the socket 100 can be increased, and the electrical connection between the two can be made more reliable. In addition, when any one set of the buttons 230 is pressed, linkage occurs between the two sets of locking members 220, so that the two sets of locking members 220 both rotate from the locked position to the unlocked position. In this way, it is convenient for the operator to operate. Of course, in other embodiments, the two sets of locking components are independent of each other and may not be set as a linkage structure.

[0062] Refer to Figure 6 , Figures 9 to 11 , in some embodiments, the first connecting arm 223 has a groove 2231, and the second connecting arm 224 has a protrusion 2241. The protrusion 2241 extends into the groove 2231. When one set of the buttons 230 is pressed to drive the corresponding locking member 220 to rotate, the protrusion 2241 abuts against the groove wall of the groove 2231 to drive the other set of locking members 220 to rotate synchronously and in the opposite direction.

[0063] Specifically, one set of locking members 220 has a first connecting arm 223 extending outward from the rotating shaft 222. A groove 2231 is provided at one end of the first connecting arm 223 facing away from the rotating shaft 222. The other set of locking members 220 has a second connecting arm 224 extending outward from the rotating shaft 222. A protrusion 2241 is provided at one end of the second connecting arm 224 facing away from the rotating shaft 222. When pressing the button 230 corresponding to one set of locking members 220, the button 230 will push the rod portion 221 of this set of locking members 220 to rotate inwardly towards the plug housing 260 around its rotating shaft 222. At the same time, the first connecting arm 223 of this set of locking members 220 rotates synchronously, so that the groove wall of the groove 2231 abuts against the protrusion 2241, lifting the protrusion 2241, causing the second connecting arm 224 of the other set of locking members 220 to also rotate inwardly towards the plug housing 260 around its rotating shaft 222, thereby enabling the locking blocks 2211 of the two sets of locking members 220 to disengage from the corresponding card slots 131.

[0064] Alternatively, in other embodiments, the meshing structure of the protrusion 2241 and the groove 2231 in the above embodiment can be replaced with a tooth meshing structure. Thus, when the first connecting arm 223 rotates, the second connecting arm 224 can also rotate synchronously and in the opposite direction through meshing.

[0065] Refer to Figure 6 、 Figures 9 to 11 In some embodiments, each locking member 220 in each set of locking assemblies includes a first connecting arm 223 and a second connecting arm 224. The first connecting arms 223 in each set of locking assemblies are meshed with the second connecting arms 224 in the other set of locking assemblies.

[0066] Specifically, each set of locking members 220 has a set of first connecting arms 223 and also has a set of second connecting arms 224. The protrusions 2241 on the first connecting arms 223 in each set of locking members 220 extend into the corresponding grooves 2231 on the second connecting arms 224 in the other set of locking members 220. When pressing one set of buttons 230 to drive the corresponding locking members 220 to rotate, each protrusion 2241 abuts against the groove wall of the groove 2231 it extends into, so as to drive the other set of locking members 220 to rotate synchronously and in the opposite direction.

[0067] Specifically, the first connecting arm 223 and the second connecting arm 224 are respectively connected to both ends of the rotating shaft 222. In this way, synchronous reverse rotation can be achieved between the two sets of locking members 220 through the two sets of cooperating convex blocks 2241 and grooves 2231, which can improve the smoothness and reliability of the linkage rotation of the two sets of locking members 220. In addition, when each set of locking members 220 has a first connecting arm 223 and a second connecting arm 224, the structural consistency of the two sets of locking members 220 can be achieved, that is, the structures of the two sets of locking members 220 are completely the same, and only symmetric assembly is required during assembly. In this way, the manufacturing cost can be reduced.

[0068] Of course, in other embodiments, the structures of the two sets of locking members 220 can also be set differently. For example, one set of locking members 220 has two first connecting arms 223, and the other set of locking members 220 has two second connecting arms 224.

[0069] Refer to Figure 3 In some embodiments, the plug 200 includes a plug housing 260 and a protective member 270. A part of the button 230 protrudes outward from the outer wall of the plug housing 260, and the protective member 270 is disposed around the button 230 on the plug housing 260.

[0070] Specifically, the protective member 270 is disposed around the outer circle of the button 230 and protrudes from the outer wall of the plug housing 260, and the size of the button 230 protruding from the outer wall of the plug housing 260 is not greater than the size of the protective member 270 protruding from the outer wall of the plug housing 260.

[0071] Further, the area of the outer wall of the plug housing 260 corresponding to the button 230 is hollowed out to allow the button 230 to protrude and be exposed, so that the operator can press the button 230. The protective member 270 protrudes outward from the outer wall of the plug housing 260. The protective member 270 is annular and sleeved on the outside of the button 230. The size of the button 230 protruding from the outer wall of the plug housing 260 is not greater than the size of the protective member 270 protruding from the outer wall of the plug housing 260, that is, the top surface of the protective member 270 is not lower than the top surface of the button 230. In this way, the button 230 can be protected by the protective member 270, making the button 230 not easily knocked and damaged, and preventing the operator from accidentally touching the button 230.

[0072] Refer to Figures 4 to 6 , in some embodiments, the socket 100 includes a top block 122. When the plug 200 is inserted into the socket 100, one end of the first elastic member 121 abuts against the top block 122, and the other end abuts against the socket housing 130. The pressing plate 251 compresses the first elastic member 121 through the top block 122.

[0073] Specifically, when the locking member 220 reaches the unlocking position, the first elastic member 121 pushes the abutting block 261 through the top block 122, and then pushes the pressing plate 251 fixed to the abutting block 261, so that the plug 200 is withdrawn from the socket 100. Further, a support platform 123 spaced from the top block 122 is further provided in the socket housing 130, and the support platform 123 is fixed to the socket housing 130. The top block 122 is hollow inside, the first elastic member 121 extends into the top block 122, one end abuts against the top block 122, and the other end abuts against the support platform 123. When the plug 200 is inserted into the socket 100, the abutting block 261 will press down the top block 122, causing the first elastic member 121 to deform and compress. When separating the plug 200 from the socket 100, the first elastic member 121 stretches and returns, pushing the top block 122 to reset, and the top block 122 will push the abutting block 261, and then push the plug 200 out of the socket 100.

[0074] The magnetic resonance imaging device provided by an embodiment of the present application includes the coil plugging module in any of the foregoing embodiments, and further includes a magnetic resonance coil and a control system. One of the magnetic resonance coil and the control system is connected to the socket 100, and the other is connected to the plug 200.

[0075] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0076] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
