Description

Technical Field

[0001] This utility model relates to the field of magnetic resonance technology, and in particular to a current lead plug structure for a magnetic resonance superconducting magnet. Background Technology

[0002] Magnetic resonance refers to the phenomenon of spin magnetic resonance. Its meaning is broad, encompassing nuclear magnetic resonance, electron paramagnetic resonance, or electron spin resonance.

[0003] However, in the existing technology, the power plug of the existing magnetic resonance does not protect the superconducting internal insert when not in use, which can lead to the accumulation of debris in the recess of the plug and around the insert, thus affecting the power transmission. In order to address the above problems, we have introduced a current lead plug structure for magnetic resonance superconducting magnets. Utility Model Content

[0004] This utility model discloses a current lead plug structure for a magnetic resonance superconducting magnet, aiming to solve the technical problem that when the power plug of a magnetic resonance is not in use, the internal inserts are not protected, which leads to debris accumulating in the recess of the plug and around the inserts, thus affecting the power transmission.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A current lead plug structure for a magnetic resonance superconducting magnet includes a plug, power rods fixedly connected at equal intervals inside the plug, and a sliding groove formed on the inner wall of the plug. A first sliding rod is fixedly connected inside each of the sliding grooves, and a first slider is slidably connected to the outer side of each of the first sliding rods. A first spring is fixedly connected between the first slider and the sliding groove and to the outer side of each first sliding rod. A movable plate is fixedly connected between multiple first sliders, and the power rods all penetrate the movable plate. Protective tubes are fixedly connected at equal intervals to one side of the movable plate, and the power rods are all located inside the protective tubes.

[0006] By design, during the transportation of the plug, some external debris will be blocked by the elasticity of the first spring, preventing it from entering the plug's interior. The protective tube protects the power rod, preventing debris from adhering to its surface. By connecting the power rod to the corresponding socket, during insertion, it will press against the protective tube, causing the connecting plate to retract inward, thus allowing for normal power connection.

[0007] In a preferred embodiment, a T-groove is provided on the outer side of the plug, a connecting plate is slidably connected to the inner wall of the T-groove, and second slide rods are equidistantly slidably connected to the outer side of the connecting plate, with connecting sleeves fixedly connected between one end of a plurality of second slide rods.

[0008] By setting up the connection sleeve to connect with the docking device, rotating the connection sleeve allows the threads on the inner wall to connect with the docking device, thus fixing the plug in place.

[0009] In a preferred embodiment, a second slider is fixedly connected at equal intervals to both sides of the connecting plate, and the sliders are slidably connected to the T-groove.

[0010] By configuring the second slider to slide inside the T-slot, it is ensured that the connecting plate will not fall off during rotation.

[0011] In a preferred embodiment, a limiting block is fixedly connected to the end of the second slide rod away from the connecting sleeve, and a second spring is fixedly connected between the limiting block and the connecting plate and located on the outside of the second slide rod.

[0012] By utilizing the elasticity of the second spring, the connection sleeve can be easily mated.

[0013] In a preferred embodiment, a sealing ring is fixedly connected to one end of the plug.

[0014] By setting up a sealing ring, a sealing effect can be achieved during connection.

[0015] In a preferred embodiment, one end of the plug is fixedly connected to a lead wire, and a protective block is fixedly connected to one end of the plug and outside the lead wire.

[0016] By configuring the protection block, the connection between the lead wire and the plug can be protected.

[0017] The current lead plug structure of the magnetic resonance superconducting magnet provided by this utility model has the following advantages: Firstly, during the transportation of the plug, some external debris will be blocked by the elasticity of the first spring, preventing it from entering the plug. The protective tube protects the power rod, preventing debris from adhering to its surface. By connecting the power rod to the corresponding socket, during insertion, it will press against the protective tube, causing the connecting plate to retract inward, thus allowing normal power connection. Secondly, the connecting sleeve is connected to the docking device. By rotating the connecting sleeve, the threads on the inner wall can be threaded to the docking device, thus fixing the plug. The elasticity of the second spring facilitates the docking of the connecting sleeve. The second slider slides inside the T-groove, preventing it from falling off during the rotation of the connecting plate. The protective block protects the connection between the lead wire and the plug. The sealing ring provides a sealing effect during connection. Attached Figure Description

The protective tube 7 protects the power rod 2, preventing debris from adhering to the surface of the power rod 2. By connecting the power rod 2 to the corresponding socket, during the insertion process, it will press against the protective tube 7, causing the connecting plate 9 to retract inward, thus allowing normal power connection.

[0036] In this embodiment, the connection between the lead wire 16 and the plug 1 can be protected by the protective block 15.

[0037] Working principle: During use, when the plug 1 is being transported, some external debris will be blocked by the elasticity of the first spring 5, which allows the connecting plate 9 to prevent it from entering the interior of the plug 1. The protective tube 7 protects the power rod 2, preventing debris from adhering to the surface of the power rod 2. By connecting the power rod 2 to the corresponding socket, during the insertion process, it will press against the protective tube 7, causing the connecting plate 9 to retract inward, thus allowing normal power connection. The connecting sleeve 12 is connected to the docking device. Rotating the connecting sleeve 12 allows the threads on the inner wall to connect with the docking device, thus fixing the plug 1. The elasticity of the second spring 14 facilitates the docking of the connecting sleeve 12. The second slider 10 slides inside the T-groove 8, preventing it from falling off during the rotation of the connecting plate 9. The protective block 15 protects the connection between the lead wire 16 and the plug 1. The sealing ring 18 provides a sealing effect during connection.
