Description

Technical Field

[0001] This invention relates to the field of nuclear fusion engineering technology, and more particularly to an electrical connection assembly and a fusion device having the electrical connection assembly. Background Technology

[0002] Magnetic confinement controlled nuclear fusion energy is an inexhaustible, clean, and safe new energy source. The China Fusion Engineering Test Reactor (CFETR), currently under construction in my country, is a major project to verify the feasibility of future commercial fusion reactors. Its fusion reactor blanket system, as one of the key systems of the CFETR, is installed inside a ring-shaped, sealed vacuum chamber. It consists of numerous shielding blocks, a first wall, piping systems, and other connecting components. Individual shielding blocks and first wall components are large in size and weigh several tons. The fusion reactor blanket is the first point of contact with the reacting plasma. Under harsh environments such as high temperature, high magnetic field, and high radiation, the fusion reactor blanket is prone to damage and requires regular inspection and replacement. In nuclear fusion devices, the fusion reactor blanket is often installed in separate modules. These modules are numerous, large in size and weight, and have irregular curved surfaces, which leads to large and inconsistent processing and assembly errors. In addition, traditional electrical connection structures require screw fixing, which limits the working space in a confined space. Furthermore, the poor conductivity of bolts makes them prone to burning and damage under high current loads, making bolt disassembly and assembly difficult or impossible. This makes disassembly and assembly operations extremely challenging and leaves room for improvement. Summary of the Invention

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] The following is for reference. Figures 1-11 The electrical connection assembly 100 according to an embodiment of the present invention can shorten the disassembly and assembly time of the fusion reactor blanket and the vacuum chamber in a confined working space by means of direct plug-in installation. Moreover, the position of the fusion reactor blanket can float relative to the mounting base 13 along the plugging direction, which can realize the self-adjustment capability of the fusion reactor blanket, reduce the difficulty of disassembly and assembly, and improve the versatility of the electrical connection assembly 100.

[0033] like Figures 1-11 As shown, according to an embodiment of the present invention, an electrical connection assembly 100 is adapted to be connected between the fusion reactor blanket and the vacuum chamber, and the electrical connection assembly 100 includes: a socket assembly 1 and an electrical connection plug 2.

[0034] Specifically, an electrical connection assembly 100 is provided between the fusion reactor blanket and the vacuum chamber. That is, the fusion reactor blanket and the vacuum chamber can be connected through the electrical connection assembly 100, and the electrical connection assembly 100 has a conductive function. In this way, the current at the fusion reactor blanket can be guided and output through the electrical connection assembly 100. Thus, the electrical connection assembly 100 has two functions, reducing the number of connection structures between the fusion reactor blanket and the vacuum chamber and the conductive structures for current conduction, thereby reducing processing costs and installation costs.

[0035] In this configuration, one of the socket assembly 1 and the electrical connector 2 is connected to the fusion reactor blanket and the other is connected to the vacuum chamber. That is, the socket assembly 1 can be connected to the fusion reactor blanket and the electrical connector 2 can be connected to the vacuum chamber, or the socket assembly 1 can be connected to the vacuum chamber and the electrical connector 2 can be connected to the fusion reactor blanket. With both configuration methods, the connection and fixation between the fusion reactor blanket and the vacuum chamber can be achieved through the plugging and matching of the socket assembly 1 and the electrical connector 2. The configuration methods are diverse and can be flexibly selected.

[0036] In this embodiment, a socket assembly 1 is connected to the vacuum chamber, and an electrical connector 2 is connected to the fusion reactor blanket. The socket assembly 1 can be detachably connected to the inner wall of the vacuum chamber, facilitating the installation and disassembly of the two. The electrical connector 2 can be detachably connected to the fusion reactor blanket, facilitating the installation and disassembly of the two. This achieves both the convenience and detachability of the connection between the fusion reactor blanket and the vacuum chamber.

[0037] It should also be noted that the fusion reactor blanket, as one of the key structures of the nuclear fusion engineering test reactor, is installed inside a ring-shaped sealed vacuum chamber. The fusion reactor blanket is the first contact surface with the reactive plasma. During the nuclear fusion reaction, a large amount of current is generated and acts on the fusion reactor blanket. Thus, by connecting the fusion reactor blanket with the electrical connector 2, an electrical connection between the two can be achieved, allowing the large amount of current generated to be discharged from the fusion reactor blanket through the electrical connector 2, thereby reducing damage to the fusion reactor blanket.

[0038] The socket assembly 1 includes a socket 11, a flexible connector 12, and a mounting base 13. The flexible connector 12 is installed in the socket 11 and is used to connect and engage with the electrical connector plug 2.

[0039] Specifically, the socket assembly 1 is used for plugging into the electrical connector 2. The flexible connector 12 is installed inside the insert 11, allowing the flexible connector 12 to be fixed relative to the insert 11. The flexible connector 12 can be installed in the insert 11 by plugging it in. The flexible connector 12 is used to plug into the electrical connector 2, allowing the electrical connector 2 to connect to the flexible connector 12, and thus to the insert 11. This plug-in connection simplifies the connection between the flexible connector 12 and the insert 11, and also simplifies the connection between the electrical connector 2 and the fusion reactor blanket. Since the electrical connector 2 is connected to the fusion reactor blanket, the connection between the fusion reactor blanket and the insert 11 is also simplified, and the disassembly and reassembly of the fusion reactor blanket and the insert 11 are made easier and more convenient.

[0040] Furthermore, the flexible connector 12 has a certain elastic deformation capacity, allowing the electrical connector 2 to extend into the flexible connector 12 and elastically press against it. This elastic pressing ensures a tight fit between the electrical connector 2 and the flexible connector 12, improving the tightness and reliability of the connection. The elastic pressing also allows for adjustment of the installation position of the electrical connector 2 relative to the flexible connector 12, enabling adjustable installation and further enhancing connection reliability. The flexible connector 12 can be made of copper, i.e., it can be constructed as a copper spring, making it conductive and improving the smoothness of current flow between the electrical connector 2 and the flexible connector 12.

[0041] It should be noted that the fusion reactor blanket comprises numerous shielding blocks, a first wall, piping systems, and other connecting components. Individual shielding blocks and first wall assemblies are large in size and weigh several tons. The fusion reactor blanket is the first point of contact with the reactive plasma, and under harsh environments such as high temperature, high magnetic field, and high radiation, damage is common during use, making regular inspection and replacement of fusion reactor blanket components unavoidable. The plug-in connection between the electrical connector 2 and the socket assembly 1 facilitates the easy assembly and disassembly of the shielding blocks, enabling convenient removal and replacement when the shielding blocks are damaged, thus improving the maintenance efficiency of the fusion reactor blanket. Furthermore, traditional electrical connection structures require screw fixation, making assembly and disassembly in confined spaces difficult and cumbersome. Bolts also have poor conductivity and are prone to burning out under high current loads, leading to difficulties or even inability to remove them. The plug-in connection facilitates operation of the fusion reactor blanket, reduces operating space, lowers operational difficulty, and eliminates the need to consider bolt removal, improving operational feasibility.

[0042] Furthermore, the insertion base 11 can float relative to the mounting base 13 along the insertion direction of the electrical connector 2, so that the insertion base 11 can float relative to the mounting base 13. The insertion base 11 can also float and adjust relative to the mounting base along the insertion direction of the electrical connector 2. The insertion base 11 is connected to the electrical connector 2 through the elastic connector 12. In this way, the position of the electrical connector 2 can float relative to the mounting base 13 along the insertion direction. Since the electrical connector 2 is connected to the fusion reactor blanket, the fusion reactor blanket can float with the electrical connector 2 relative to the mounting base 13.

[0043] It should be noted that the fusion reactor blanket is large in size, and the machining error of the parts also increases accordingly. In addition, there are many mating parts, which makes it impossible to install the traditional rigid connection structure under the cumulative error. By setting the position of the electrical connection plug 2 to float relative to the mounting base 13 along the insertion direction, the installation error between the fusion reactor blanket and the mounting base 13 can be compensated, ensuring a stable connection under different error conditions and improving the installation reliability of the fusion reactor blanket.

[0044] According to the electrical connection assembly 100 of the present invention, the connection between the fusion reactor blanket and the insertion base 11 is simple and convenient through the plug-in cooperation of the electrical connection plug 2 and the elastic plug 12. This direct plug-in installation method ensures that the current transmission connection is normal without the need for disassembly and assembly of fasteners such as screws, which can greatly reduce the disassembly and assembly time in confined working spaces, improve the convenience of operation and assembly efficiency. Moreover, the elastic pressing cooperation between the electrical connection plug 2 and the elastic plug 12 makes the connection between the two highly tight, which can improve the installation reliability of the fusion reactor blanket. Furthermore, by floating the insertion base 11 relative to the mounting base 13, the position of the electrical connection plug 2 can float relative to the mounting base 13 along the plugging direction, which can realize the self-adjustment capability of the electrical connection plug 2 within a certain range, so as to compensate for the cumulative errors generated during the processing and assembly of various parts of the fusion reactor blanket, avoid problems such as repeated installation and secondary processing of parts, greatly reduce the difficulty of disassembly and assembly, improve the versatility of the electrical connection assembly 100, and the connection process is simple and the use effect is good.

[0045] In some embodiments, the socket assembly 1 further includes a guide cylinder 15, an insert 11 is tunably mounted on the guide cylinder 15, a mounting base 13 is connected to one end of the guide cylinder 15, and the insert 11 is electrically connected to the mounting base 13.

[0046] Specifically, the insertion seat 11 is installed in an adjustable position on the guide cylinder 15, allowing the insertion seat 11 to be adjusted relative to the guide cylinder 15, thus achieving a floating connection between the insertion seat 11 and the guide cylinder 15. The insertion seat 11 is connected to the electrical connector 2 through the elastic plug 12, thereby allowing the position of the electrical connector 2 to be adjusted relative to the guide cylinder 15. In actual installation, the electrical connector 2 can be adjusted by floating with the insertion seat 11 relative to the guide cylinder 15, and the guiding effect of the guide cylinder 15 can improve the adjustment accuracy of the position of the electrical connector 2. Furthermore, the electrical connector 2 is connected to the fusion reactor blanket, thereby improving the installation accuracy of the fusion reactor blanket.

[0047] Thus, through the above settings, the electrical connection plug 2 can achieve self-adjustment within a certain range to compensate for the cumulative errors generated during the processing and assembly of various parts of the fusion reactor blanket, avoid problems such as repeated installation and secondary processing of parts, greatly reduce the difficulty of disassembly and assembly, and improve the versatility of the electrical connection assembly 100.

[0048] The mounting base 13 is connected to one end of the guide cylinder 15, and the mounting base 13 is connected to the vacuum chamber, so that the guide cylinder 15 is fixed relative to the vacuum chamber. Thus, the guide cylinder 15 is a fixed end, and the insertion seat 11 can move relative to the guide cylinder 15. The mounting base 13 and the guide cylinder 15 can be detachably connected by fasteners such as bolts, which can improve the connection strength between the mounting base 13 and the guide cylinder 15, and facilitate the disassembly, assembly and maintenance of the mounting base 13 and the guide cylinder 15.

[0049] Furthermore, the insertion socket 11 is electrically connected to the mounting base 13. The insertion socket 11 can be connected to the mounting base 13 through an electrical connection structure, which enables circuit conduction between the insertion socket 11 and the mounting base 13. The insertion socket 11 is also electrically connected to the electrical connection plug 2 through the elastic connector 12, which allows current to be sequentially conducted between the electrical connection plug 2, the elastic connector 12, the insertion socket 11, and the mounting base 13. This facilitates the discharge of current from the fusion reactor blanket through the electrical connection assembly 100, thereby reducing the damage of current to the fusion reactor blanket.

[0050] In some embodiments, a guide cavity 151 is formed in the guide cylinder 15, the guide cavity 151 is open at one end away from the mounting base 13, the insertion seat 11 is movably mounted in the guide cavity 151, and at least a portion of the insertion seat 11 extends out from the open end of the guide cavity 151.

[0051] Specifically, the guide cavity 151 is used for the installation and movement of the insertion seat 11, such as... Figure 2 and Figure 7 As shown, the guide cavity 151 is open at one end away from the mounting base 13, allowing the insertion seat 11 to be avoided at the end of the guide cavity 151 away from the mounting base 13. At least a portion of the insertion seat 11 can extend from the open end of the guide cavity 151, and the insertion seat 11 is used to connect with the electrical connector 2. The structure of at least a portion of the extended insertion seat 11 is close to the electrical connector 2, which facilitates the connection between the end of the insertion seat 11 away from the mounting base 13 and the electrical connector 2. The insertion seat 11 can move along the length of the guide cavity 151, so that the electrical connector 2 moves with the insertion seat 11.

[0052] Furthermore, by extending at least a portion of the insertion seat 11 out of the guide cavity 151, a portion of the insertion seat 11 can extend out of the guide cavity 151 while the other portion remains within the guide cavity 151, thereby limiting the insertion seat 11.

[0053] The guide cylinder 15 is cylindrical, and the guide cavity 151 can also be cylindrical, extending axially along the guide cylinder 15 to form an open end at the end of the guide cylinder 15 away from the mounting base 13, thus avoiding the insertion seat 11. The insertion seat 11 can also be cylindrical, allowing its shape to better match the shape of the guide cavity 151, facilitating connection between the insertion seat 11 and the guide cylinder 15 along the length of the guide cavity 151. Furthermore, the guide cavity 151 has an open side at the end near the mounting base 13, allowing the insertion seat 11 to be inserted from the end of the guide cavity 151 near the mounting base 13 to the end of the guide cavity 151 away from the mounting base 13, achieving a guiding connection between the insertion seat 11 and the guide cylinder 15. This design is simple in structure, easy to manufacture, and has low manufacturing costs.

[0054] In addition, it should be noted that the insertion seat 11 and the guide cylinder 15 can also be constructed as other guiding structures, as long as the insertion seat 11 can float relative to the mounting base 13.

[0055] In some embodiments, the inner peripheral wall of the guide cavity 151 away from the mounting base 13 is provided with a first limiting part 152, and the outer peripheral wall of the insertion seat 11 near the mounting base 13 is provided with a second limiting part 111. The second limiting part 111 limits and presses against the side of the first limiting part 152 facing the mounting base 13.

[0056] In other words, by limiting and pressing the first limiting part 152 and the second limiting part 111, at least a part of the structure of the insertion seat 11 can be limited within the guide cavity 151, so as to limit the insertion seat 11 along the axial direction of the guide cavity 151, prevent the insertion seat 11 from extending out of the guide cavity 151, and improve the installation reliability of the insertion seat 11 and the guide cylinder 15.

[0057] Specifically, such as Figure 2 and Figure 7As shown, the guide cavity 151 is provided with a first limiting part 152, which is located at the end of the guide cavity 151 away from the mounting base 13, that is, the first limiting part 152 is close to the electrical connector 2. The first limiting part 152 is constructed to protrude inward on the inner peripheral wall of the guide cavity 151, and the first limiting part 152 has a side facing the mounting base 13. In actual design, the first limiting part 152 can be constructed to form a stepped surface on the inner peripheral wall of the guide cavity 151. The insertion seat 11 is provided with a second limiting part 111, which is located at the end of the insertion seat 11 close to the mounting base 13. The second limiting part 111 is constructed to protrude from the insertion seat 11... The outer peripheral wall protrudes outward, and the second limiting part 111 has a limiting surface that is opposite to the mounting base 13. During installation, after the insertion seat 11 is inserted into the guide cylinder 15 along the length direction of the guide cavity 151 from the end of the guide cavity 151 near the mounting base 13, when the limiting surface of the second limiting part 111 is pressed against the side of the first limiting part 152, the insertion seat 11 and the guide cylinder 15 are axially limited. At this time, the distance between the insertion seat 11 and the mounting base 13 is the farthest, which can limit the farthest installation position of the insertion seat 11 and the mounting base 13. This position is also the maximum floating position of the insertion seat 11 relative to the mounting base 13 along the insertion direction of the electrical connector 2.

[0058] Therefore, by using the side of the first limiting part 152 to axially limit the limiting surface of the second limiting part 111, the limiting mating area of ​​the first limiting part 152 and the second limiting part 111 can be increased, thereby improving the axial limiting reliability of the insertion seat 11 and the guide cylinder 15.

[0059] The first limiting part 152 can extend circumferentially along the guide cavity 151, and the second limiting part 111 can extend circumferentially along the insertion seat 11, increasing the circumferential mating area between the first limiting part 152 and the second limiting part 111, thereby improving the limiting reliability between them. Furthermore, the first limiting part 152 and the second limiting part 111 are correspondingly distributed, facilitating the limiting mating of the first limiting part 152 and the second limiting part 111. There can be multiple first limiting parts 152 and second limiting parts 111, such as... Figure 7 As shown, there are four first limiting parts 152, which are evenly spaced apart along the circumference of the guide cylinder 15, and as... Figure 4 As shown, there are four second limiting parts 111, and the four second limiting parts 111 are distributed in a one-to-one correspondence with the four first limiting parts 152.

[0060] In some embodiments, the sidewall of the guide cavity 151 is formed with a guide groove 153 extending axially, and the outer end of the insertion seat 11 is formed with a guide protrusion 112, which extends into the guide groove 153 and guides the guide cylinder 15 axially.

[0061] In other words, through the guiding engagement of the guide protrusion 112 and the guide groove 153, the insertion seat 11 and the guide movable cavity 151 can be guided and connected. Furthermore, through the guiding engagement, the axial insertion engagement between the insertion seat 11 and the guide movable cavity 151 can be highly reliable, preventing the insertion seat 11 from circumferentially moving relative to the guide movable cavity 151. This makes the axial position change of the insertion seat 11 relative to the guide movable cavity 151 stable and reliable, thereby improving the reliability of the floating adjustment of the insertion seat 11 relative to the mounting base 13.

[0062] Specifically, such as Figure 7 As shown, a guide groove 153 is formed on the sidewall of the guide cavity 151. The guide groove 153 can penetrate radially through the sidewall of the guide cavity 151, such as... Figure 4 As shown, a guide protrusion 112 is formed at the outer end of the insertion seat 11. The guide protrusion 112 protrudes outward on the surface of the insertion seat 11. The size of the guide protrusion 112 is smaller than the size of the guide groove 153, so that the guide protrusion 112 can extend into the guide groove 153. The guide groove 153 extends along the axial direction of the guide movable cavity 151, so that the guide protrusion 112 can be guided and engaged axially when it extends into the guide groove 153, thereby realizing the axial insertion connection between the insertion seat 11 and the guide movable cavity 151.

[0063] By extending the guide protrusion 112 into the guide groove 153, the radial insertion area between the guide protrusion 112 and the guide groove 153 is increased, improving the reliability of the guiding fit between the guide protrusion 112 and the guide groove 153. Furthermore, the guide groove 153 has an open end near the mounting base 13, facilitating the extension of the guide protrusion 112 into the guide groove 153. The guide groove 153 can extend to connect with the first limiting part 152, meaning the end of the guide groove 153 away from the mounting base 13 is flush with the end of the first limiting part 152 near the mounting base 13. This facilitates axial positioning of the guide protrusion 112 by the guide groove 153 and also facilitates the machining of the guide groove 153 and the first limiting part 152. Additionally, the end of the guide protrusion 112 away from the mounting base 13 is flush with the end of the second limiting part 111 away from the mounting base 13, further facilitating the machining of both the guide protrusion 112 and the second limiting part 111.

[0064] Furthermore, the protrusion height of the guide protrusion 112 relative to the insertion seat 11 is greater than the protrusion height of the second limiting part 111 relative to the insertion seat 11. In this way, the limiting cooperation between the second limiting part 111 and the first limiting part 152 in the guide movable cavity 151 can be realized, and the insertion cooperation between the guide protrusion 112 and the guide groove 153 can also be realized.

[0065] The guide protrusion 112 and guide groove 153 can each be provided in multiples, that is, the guide protrusion 112 and guide groove 153 can each be provided in two, three, four, etc. In this embodiment, for example... Figure 7 As shown, there are two guide grooves 153, and the two guide grooves 153 are evenly spaced apart along the circumference of the guide cylinder 15, that is, they are distributed opposite each other along the side wall of the guide cylinder 15. Correspondingly, there are two guide protrusions 112, and the two guide protrusions 112 are distributed one-to-one with the two guide grooves 153, so that the two guide protrusions 112 can be inserted into the two guide grooves 153 one-to-one.

[0066] In some embodiments, the socket assembly 1 further includes an elastic adjustment piece 16 and an elastic pretensioner 14, the elastic adjustment piece 16 being located within the guide cavity 151, and the elastic pretensioner 14 being elastically pressed between the elastic adjustment piece 16 and the insertion seat 11.

[0067] That is, the elastic pretensioner 14 elastically presses against the elastic adjusting piece 16 and the insertion seat 11 respectively. The elastic pretensioner 14 has elastic compressibility, and the elastic adjusting piece 16 has adjustability. That is, by adjusting the position of the elastic adjusting piece 16 relative to the insertion seat 11, the deformation of the elastic pretensioner 14 can be adjusted, thereby adjusting the pretension force of the elastic pretensioner 14 on the insertion seat 11 to ensure the installation reliability of the insertion seat 11.

[0068] Specifically, the elastic adjustment piece 16 is located inside the guide cavity 151, that is, the elastic adjustment piece 16 is installed inside the guide cavity 151 and is distributed close to the mounting base 13. The elastic pre-tightening member 14 is located between the elastic adjustment piece 16 and the insertion seat 11. One end of the elastic pre-tightening member 14 elastically abuts against the elastic adjustment piece 16 and the other end elastically abuts against the insertion seat 11. Both the elastic pre-tightening member 14 and the elastic adjustment piece 16 are located on the side of the insertion seat 11 close to the mounting base 13, so that the elastic adjustment piece 16 and the elastic pre-tightening member 14 can elastically abut against the end of the insertion seat 11 close to the mounting base 13, thereby achieving pre-tightening of the insertion seat 11.

[0069] In some embodiments, the mounting base 13 is provided with a movable adjustment member 131, at least a portion of which extends into the guide cavity 151 and presses against the elastic adjustment piece 16, and is used to adjust the distance between the elastic adjustment piece 16 and the insertion seat 11.

[0070] Specifically, the mounting base 13 is provided with a movable adjusting member 131. For example, the adjusting member 131 can be detachably connected to the mounting base 13, and the adjusting member 131 can move relative to the mounting base 13. At least a portion of the adjusting member 131 extends into the guide movable cavity 151. That is, a part of the structure of the adjusting member 131 can be arranged to extend axially into the guide movable cavity 151, and the part of the adjusting member 131 extending into the guide movable cavity 151 can press against the side of the elastic adjusting piece 16 away from the elastic pre-tightening member 14. Thus, the adjusting member 131 can apply a force to the elastic adjusting piece 16, thereby causing the elastic adjusting piece 16 to apply a force to the elastic pre-tightening member 14. By adjusting the axial length of the adjusting member 131 extending into the guide movable cavity 151, the magnitude of the force exerted by the adjusting member 131 on the elastic adjusting piece 16 can be adjusted, thereby changing the distance between the elastic adjusting piece 16 and the insertion seat 11, so as to adjust the elastic force of the elastic pre-tightening member 14.

[0071] Among them, such as Figure 6 As shown, the elastic preload 14 can be constructed as a compression spring, and the compression spring can be a circular spring. When the axial length of the adjusting member 131 extending into the guide movable cavity 151 increases, that is, the force on the elastic adjusting piece 16 increases, causing the elastic adjusting piece 16 to move towards the insertion seat 11, which can reduce the distance between the elastic adjusting piece 16 and the insertion seat 11, thereby increasing the compression amount of the elastic preload 14, and thus increasing the force of the elastic preload 14 on the insertion seat 11, so as to improve the preload force of the elastic preload 14 on the insertion seat 11. Conversely, when the axial length of the adjusting member 131 extending into the guide movable cavity 151 decreases, that is, the force on the elastic adjusting piece 16 decreases, causing the elastic adjusting piece 16 to move away from the insertion seat 11, which can increase the distance between the elastic adjusting piece 16 and the insertion seat 11, thereby reducing the compression amount of the elastic preload 14, and thus reducing the force of the elastic preload 14 on the insertion seat 11, so as to reduce the preload force of the elastic preload 14 on the insertion seat 11. Compression springs can also be constructed as rectangular springs, etc.

[0072] Therefore, through the above-mentioned setting and adjustment methods, the adjustment of the pre-tightening force of the elastic pre-tightening member 14 on the insertion seat 11 can be made simpler, making the installation of the insertion seat 11 more convenient and reliable, and the structure is simple and the cost is low.

[0073] Furthermore, the guide cylinder 15 is provided with a guide groove 153, and the insertion seat 11 is provided with a guide protrusion 112. Through the guiding cooperation of the guide protrusion 112 and the guide groove 153, it is ensured that the insertion seat 11 only compresses the elastic preload 14 in the axial direction, so as to avoid improper installation, the elastic preload 14 generating torque, and damaging the components.

[0074] In some embodiments, the mounting base 13 is provided with an adjustment hole 132, and the adjustment member 131 passes through the adjustment hole 132 and is threadedly engaged with the mounting base 13.

[0075] Specifically, the adjustment hole 132 is used to install the adjustment member 131. The adjustment hole 132 passes through the mounting base 13 axially, allowing the adjustment member 131 to pass through the adjustment hole 132. The adjustment member 131 is threadedly connected to the mounting base 13, that is, the adjustment member 131 is threadedly engaged with the adjustment hole 132. Thus, the adjustment member 131 can be constructed as an adjustment bolt. By rotating the adjustment bolt, the adjustment bolt can be extended into the guide movable cavity 151, and the adjustment bolt extended into the guide movable cavity 151 can be adjusted to move closer to or further away from the elastic adjustment piece 16.

[0076] Thus, by rotating the adjusting bolt closer to the elastic adjusting plate 16, the compression amount of the elastic adjusting plate 16 can be increased, thereby increasing the preload of the elastic preload 14 on the insertion seat 11. By rotating the adjusting bolt away from the elastic adjusting plate 16, the compression amount of the elastic adjusting plate 16 can be reduced, thereby reducing the preload of the elastic preload 14 on the insertion seat 11.

[0077] Among them, such as Figure 8 As shown, the adjustment hole 132 can be located in the middle of the mounting base 13, allowing the portion of the adjusting member 131 extending into the guide cavity 151 to press against the middle of the elastic adjusting piece 16. This allows the adjusting member 131 to apply force to the elastic adjusting piece 16 from the middle, improving the uniformity of force distribution on the elastic adjusting piece 16 and ensuring that the elastic adjusting piece 16 reliably presses the elastic preload member 14 along the axial direction. The adjustment hole 132 is constructed as a bolt mounting hole to achieve threaded engagement between the adjusting bolt and the adjustment hole 132. Through the threaded connection, the adjustment process of the adjusting member 131 is simple and convenient, and it is easy to adjust the compression amount of the elastic preload member 14 by the elastic adjusting piece 16.

[0078] In some embodiments, the end of the insertion seat 11 is provided with a first mounting boss 113, the elastic adjustment piece 16 is provided with a second mounting boss 161, and one end of the elastic pre-tightening member 14 is sleeved outside the first mounting boss 113 and the other end is sleeved outside the second mounting boss 161.

[0079] In other words, by fitting one end of the elastic pretensioner 14 onto the first mounting boss 113, one end of the elastic pretensioner 14 can be fixed to achieve the connection between the elastic pretensioner 14 and the insertion seat 11. By fitting the other end of the elastic pretensioner 14 onto the second mounting boss 161, the other end of the elastic pretensioner 14 can be fixed to achieve the connection between the elastic pretensioner 14 and the elastic adjusting piece 16. Thus, the elastic pretensioner 14 is installed between the insertion seat 11 and the elastic adjusting piece 16. The installation process is simple and facilitates the assembly and disassembly of the three components.

[0080] Specifically, such as Figure 2As shown, the first mounting boss 113 is located at the end of the insertion seat 11 near the mounting base 13, and the second mounting boss 161 is located at the end of the elastic adjusting piece 16 away from the mounting base 13. That is, the first mounting boss 113 and the second mounting boss 161 are distributed close to each other. The first mounting boss 113 and the second mounting boss 161 both protrude in the direction of being close to each other, and the first mounting boss 113 and the second mounting boss 161 can be constructed as circular bosses. The elastic pretensioner 14 is constructed as a compression spring. The structure of the first mounting boss 113 and the second mounting boss 161 can be the same, that is, the outer diameter of the first mounting boss 113 and the second mounting boss 161 can be set to be smaller than the inner diameter of the compression spring. In this way, the two ends of the elastic pretensioner 14 can be respectively sleeved on the first mounting boss 113 and the second mounting boss 161.

[0081] The insertion seat 11 has a circular structure. The side of the second limiting portion 111 near the first mounting boss 113 forms a first abutting surface. One end of the elastic pre-tightening member 14 is sleeved outside the first mounting boss 113 and elastically abuts against the first abutting surface, thus fixing one end of the elastic pre-tightening member 14. The elastic adjusting piece 16 can also be circular, such as... Figure 9 As shown, the elastic adjustment piece 16 is provided with a third limiting part 162 connected to the second mounting boss 161. The third limiting part 162 is formed as a second pressing surface on the side near the second mounting boss 161. The other end of the elastic pretensioner 14 is sleeved on the second mounting boss 161 and elastically presses against the second pressing surface, so as to fix the other end of the elastic pretensioner 14.

[0082] In some embodiments, the mounting base 13 includes a base body 133 and a positioning boss 134. The positioning boss 134 protrudes and is connected to one end of the base body 133 facing the insertion seat 11. The positioning boss 134 is inserted and engaged with the guide cavity 151. The end face of the guide cylinder 15 is limited and pressed against the base body 133.

[0083] Specifically, such as Figure 8As shown, the positioning boss 134 is axially connected to the base body 133, and the positioning boss 134 protrudes from the end of the base body 133 facing the insertion seat 11, so that the positioning boss 134 is close to the insertion seat 11. The positioning boss 134 can be inserted into the guide movable cavity 151 axially, which can circumferentially position the mounting base 13. The outer diameter of the positioning boss 134 can be set to be smaller than the inner diameter of the guide movable cavity 151, so that the positioning boss 134 can extend into the guide movable cavity 151 for insertion. The positioning boss 134 can be tolerance-fitted with the guide movable cavity 151 to improve the reliability of the insertion fit. The end face of the guide cylinder 15 is limited and pressed against the side of the base body 133 near the positioning boss 134, which can realize the limiting fit between the guide cylinder 15 and the base body 133. Specifically, a limiting surface can be formed on the side of the base body 133 near the positioning boss 134, and the end face of the guide cylinder 15 and the limiting surface of the base body 133 are circumferentially limited and pressed together, thereby increasing the pressing area between the two and improving the limiting and pressing reliability between the guide cylinder 15 and the base body 133.

[0084] The guide cylinder 15 can be detachably connected to the base body 133 via bolts or other fasteners. Multiple bolts can be used, spaced apart and connected circumferentially to both the guide cylinder 15 and the base body 133, improving the tightness and reliability of the connection. Furthermore, multiple bolt holes can be provided at the end of the guide cylinder 15 near the mounting base 13, and the base body 133 has multiple through holes 136. These through holes 136 are distributed one-to-one with the bolt holes, facilitating the threaded engagement of multiple bolts through the through holes 136 and bolt holes.

[0085] In some embodiments, the electrical connection assembly 100 further includes a conductive strip 3, through which the insertion socket 11 and the mounting base 13 are electrically connected. The conductive strip 3 has good conductivity, so that the insertion socket 11 and the mounting base 13 can be electrically connected through the conductive strip 3, and the current at the insertion socket 11 can flow to the mounting base 13 through the conductive strip 3. The insertion socket 11 is connected to the electrical connection plug 2 through the elastic plug 12, and the electrical connection plug 2 is connected to the fusion reactor blanket. The current generated at the fusion reactor blanket can be transmitted to the mounting base 13 in sequence through the electrical connection plug 2, the elastic plug 12, the insertion socket 11 and the conductive strip 3, so as to discharge the current at the fusion reactor blanket.

[0086] Both the conductive strip 3 and the electrical connector 2 can be made of copper, which provides conductivity. Therefore, the conductive strip 3 can be constructed as a copper conductive strip, and the electrical connector 2 can be constructed as a copper connector. Furthermore, the conductive strip 3 can be replaced with other conductive structures such as conductive rings; its configuration is not limited. Similarly, the insertion socket 11 can be made of copper, which also provides conductivity. Therefore, the insertion socket 11 can be constructed as a copper insertion socket 11, enabling circuit connection between the elastic connector 12 and the conductive strip 3.

[0087] In some embodiments, the conductive strip 3 is detachably connected to the insertion seat 11 via the first connector 4, and / or the conductive strip 3 is detachably connected to the mounting base 13 via the second connector 5.

[0088] Specifically, one end of the conductive strip 3 can be detachably connected to the insertion seat 11 via the first connector 4, and the other end of the conductive strip 3 can be detachably connected to the mounting base 13 via the second connector 5. This allows the conductive strip 3 to be detachably connected to both the insertion seat 11 and the mounting base 13. The detachable connection also facilitates the removal of the conductive strip 3 from the insertion seat 11 and the mounting base 13 if it is damaged.

[0089] The first connector 4 and the second connector 5 can both be constructed as copper bolts, with the following structure: Figure 10 As shown, the copper bolt has good electrical conductivity. Thus, connecting the conductive strip 3 to the insertion seat 11 via the copper bolt enables circuit continuity between the insertion seat 11 and the conductive strip 3. Similarly, connecting the conductive strip 3 to the mounting base 13 via the copper bolt enables circuit continuity between the mounting base 13 and the conductive strip 3. This allows the current at the insertion seat 11 to be transmitted through the copper bolt to the conductive strip 3, and then through the copper bolt to the mounting base 13. Furthermore, the good conductivity of the copper bolt reduces the possibility of damage from high currents, and the installation and removal of the copper bolt can be performed normally. The first connecting member 4 and the second connecting member 5 can be the same or different. In this embodiment, the first connecting member 4 and the second connecting member 5 have the same specifications and materials.

[0090] And such as Figure 4 As shown, the outer peripheral wall of the insertion seat 11 has a connecting plane 117, and the insertion seat 11 has a threaded hole 1171 at the connecting plane 117. Correspondingly, as shown... Figure 11As shown, the conductive strip 3 has a connecting mating surface 32 at both ends. A through hole 31 is provided at the connecting mating surface 32 at one end of the conductive strip 3. In this way, the conductive strip 3 can fit with the connecting plane 117 through the connecting mating surface 32. The first connector 4 is threaded through the through hole 31 and threaded into the threaded hole 1171, so that one end of the conductive strip 3 can be connected to the insertion seat 11. By setting the connecting plane 117, the connection between the conductive strip 3 and the insertion seat 11 can be made tight, which can improve the connection stability and conductive area.

[0091] Additionally, a through hole 31 is provided at the connecting mating surface 32 at the other end of the conductive strip 3, and a bolt hole 138 is provided on the mounting base 13. The second connector 5 is threaded through the through hole 31 and into the bolt hole 138, so that the other end of the conductive strip 3 can be connected to the mounting base 13.

[0092] In some embodiments, the first connector 4 is movably inserted into the insert 11, the elastic plug 12 is provided with a limiting engagement hole 126, and at least a portion of the first connector 4 extends into the insert 11 to be inserted into and limited by the limiting engagement hole 126.

[0093] Specifically, the first connector 4 is movably inserted into the insertion seat 11, that is, the first connector 4 can extend into or out of the insertion seat 11. When the first connector 4 extends into the insertion seat 11, the conductive strip 3 can be connected to the insertion seat 11, and when the first connector 4 extends out of the insertion seat 11, the conductive strip 3 can be detached from the insertion seat 11.

[0094] Furthermore, after at least a portion of the first connector 4 extends into the insert seat 11, the extended portion of the first connector 4 can be inserted into the limiting engagement hole 126. This allows the first connector 4 to limit the insertion of the elastic connector 12, and the elastic connector 12 and the insert seat 11 can be inserted into each other. In other words, the first connector 4 can limit the elastic connector 12 and the insert seat 11 along the insertion direction to ensure the installation reliability of the elastic connector 12 and the insert seat 11.

[0095] Among them, such as Figure 5 As shown, the limiting fitting hole 126 can be constructed as a circular hole with a diameter greater than the outer diameter of the first connector 4, which facilitates the insertion and engagement of the first connector 4 with the limiting fitting hole 126. Furthermore, the length of the first connector 4 needs to be greater than the wall thickness of the insert seat 11, so that the first connector 4 has sufficient length and can extend into the limiting fitting hole 126 to achieve the insertion and engagement of the first connector 4 with the limiting fitting hole 126.

[0096] In actual installation, the socket assembly 1 needs to be assembled first. The elastic plug 12 is inserted into the insert 11. Then, the two guide protrusions 112 on the insert 11 are guided and fitted along the guide groove 153 on the side wall of the guide cylinder 15. After that, the elastic pre-tightening member 14 and the elastic adjusting plate 16 are inserted into the guide movable cavity 151 of the guide cylinder 15 in sequence. Then, the mounting base 13 is connected to the end face of the guide cylinder 15 by bolts. The adjusting member 131 with nut 135 is screwed into the adjusting hole 132 of the mounting base 13. The adjusting member 131 is pressed against the elastic adjusting plate 16. Rotating the adjusting member 131 closer to or away from the elastic adjusting plate 16 can adjust the compression of the elastic pre-tightening member 14, thereby adjusting the pre-tightening force of the elastic pre-tightening member 14. After the adjustment is completed, the nut 135 is locked. After the socket assembly 1 is assembled, the two ends of the conductive strip 3 are fixed to the insert 11 and the mounting base 13 respectively with copper bolts.

[0097] In some embodiments, a limiting groove 155 is formed on the outer side of the guide cylinder 15, at least a portion of the conductive strip 3 passes through the limiting groove 155, and the conductive strip 3 and the inner wall of the limiting groove 155 are mutually limiting and engaged along the circumferential direction of the guide cylinder 15.

[0098] Specifically, such as Figure 7 As shown, a limiting groove 155 is formed on the outer side of the guide cylinder 15. The limiting groove 155 can penetrate radially through the side wall of the guide cylinder 15, so that the guide cylinder 15 can be connected inside and outside at the limiting groove 155. In this way, at least part of the conductive strip 3 can be inserted into the limiting groove 155, that is, the limiting groove 155 can avoid the conductive strip 3. Moreover, the size of the limiting groove 155 is larger than the size of the conductive strip 3, so that the conductive strip 3 can extend into the limiting groove 155. The inner wall of the limiting groove 155 can circumferentially limit the conductive strip 3 located inside it, so that the conductive strip 3 can be distributed along the limiting groove 155, improving the installation reliability of the conductive strip 3.

[0099] Furthermore, there can be multiple conductive strips 3, which are distributed circumferentially in the guide cylinder 15. That is, there are also multiple limiting grooves 155. The multiple limiting grooves 155 are distributed one-to-one with the multiple conductive strips 3, so that the multiple limiting grooves 155 can respectively limit the conductive strips 3 located inside them circumferentially.

[0100] Multiple conductive strips 3 allow the insertion seat 11 to be electrically connected to the mounting base 13 at multiple circumferential positions, forming multiple current conduction paths connected to the mounting base 13 in the circumferential direction of the insertion seat 11. This allows current at the insertion seat 11 to be transferred from multiple circumferential positions to the mounting base 13 via the conductive strips 3, thereby enabling the output of current from the fusion reactor blanket through multiple paths and improving the efficiency of current extraction from the fusion reactor blanket. Figure 1 As shown, there are four conductive bands 3, as follows: Figure 7 As shown, there are four limiting slots 155. Furthermore, the conductive strip 3 and the limiting slots 155 can also be set to two, three, five, six, or more. The number of conductive strips 3 can be determined according to the actual conductivity requirements.

[0101] Furthermore, multiple limiting slots 155 are spaced apart, and the multiple limiting slots 155 are spaced apart from the guide slots 153 along the circumferential direction, so that multiple conductive strips 3 can be installed through the multiple limiting slots 155 respectively, and the insertion seat 11 can be guided and engaged with the guide slot 153 through the guide protrusion 112. In this way, interference between the limiting slots 155 and the guide slots 153 can be avoided.

[0102] In some embodiments, there are two resilient plugs 12, and the two resilient plugs 12 are spaced apart and distributed opposite each other in the insert 11. A plug hole 121 for engaging with the electrical connector 2 is formed between the two resilient plugs 12, and the electrical connector 2 presses against the surfaces of the two resilient plugs 12 facing each other.

[0103] Specifically, two elastic connectors 12 are spaced apart and distributed opposite each other within the insertion base 11, allowing the two elastic connectors 12 to be connected to the interior of the insertion base 11 at a distance. A insertion hole 121 is formed between the two elastic connectors 12 for connecting the electrical connector 2. That is, the electrical connector 2 can be connected to the two elastic connectors 12 respectively through the insertion hole 121, and the electrical connector 2 presses against the surfaces of the two elastic connectors 12 facing each other. This allows the exterior of the electrical connector 2 to elastically press against the surfaces of the two elastic connectors 12 that are close to each other, thereby enabling the two elastic connectors 12 to press the electrical connector 2 tightly. This improves the reliability of the elastic pressing between the electrical connector 2 and the inner wall of the insertion hole 121, and thus improves the tightness of the connection between the electrical connector 2 and the two elastic connectors 12.

[0104] Among them, such as Figure 3As shown, the electrical connector 2 can be constructed as a circular structure. The electrical connector 2 includes a plug portion 22, the outer diameter of which is smaller than the inner diameter of the plug hole 121. The end of the plug portion 22 can be provided with a ball head chamfer 23, which facilitates the plug portion 22 to be plugged into the plug hole 121. Alternatively, the outer diameter of the plug portion 22 can be set to be smaller than or equal to the inner diameter of the plug hole 121, which facilitates the outer periphery of the plug portion 22 to effectively press against the inner wall of the plug hole 121, thereby ensuring the reliability of the elastic pressing of the two elastic plug members 12 against the electrical connector 2. Furthermore, the electrical connector 2 has a stepped portion 24 that protrudes from the outer wall of the electrical connector 2 and extends circumferentially along the electrical connector 2. This allows the step portion 24 to press against the end face of the insert 11 when the plug portion 22 is inserted into the plug hole 121. This improves the reliability of the connection between the electrical connector 2 and the insert 11.

[0105] The number of flexible connectors 12 is not limited to two; the number can be determined according to the actual conductivity requirements.

[0106] In some embodiments, the insertion seat 11 has a insertion cavity 114 and two insertion grooves 115, the two insertion grooves 115 are connected to both sides of the insertion cavity 114, and the two elastic insertion members 12 are inserted into the two insertion grooves 115 in a one-to-one correspondence.

[0107] Specifically, the insertion groove 115 is used to install the elastic connector 12, and the insertion cavity 114 is used for the insertion connection between the elastic connector 12 and the insertion seat 11, wherein, as Figure 4 As shown, two insertion grooves 115 are located on both sides of the insertion cavity 114 and are connected to both sides of the insertion cavity 114 respectively. Both insertion grooves 115 and the insertion cavity 114 are hollow structures, which can realize the installation of the elastic plug 12 and the electrical connector 2. In this way, the two elastic plugs 12 can be inserted into the two insertion grooves 115 one by one, and the two insertion grooves 115 are relatively distributed, which can make the two elastic plugs 12 relatively distributed. In addition, the two insertion grooves 115 and the insertion cavity 114 have an open side on the side away from the mounting base 13, which allows the two elastic plugs 12 and the electrical connector 2 to be inserted into the insertion socket 11 from the open end respectively.

[0108] Furthermore, the shapes of the two insertion grooves 115 need to match the shapes of the two elastic plugs 12 to facilitate reliable insertion of the two elastic plugs 12 into the corresponding insertion grooves 115. The two insertion grooves 115 and the insertion cavity 114 can be processed by material removal to form a cavity structure of two insertion grooves 115 and insertion cavity 114 in the insertion seat 11.

[0109] The insertion cavity 114 forms two insertion walls 116 between two insertion grooves 115, and the two insertion walls 116 and the surfaces of the two elastic insertion members 12 facing each other together define the insertion hole 121.

[0110] Specifically, the two plug-in walls 116 can be used for connecting the electrical connector 2. The two plug-in walls 116 are formed between the two plug-in grooves 115 and are distributed opposite to each other. After the two elastic plugs 12 are installed in the two plug-in grooves 115 in a one-to-one correspondence, the surfaces of the two elastic plugs 12 facing each other and the two plug-in walls 116 can jointly define the plug hole 121. In this way, the surfaces of the two elastic plugs 12 facing each other and the two plug-in walls 116 can be used for plug-in connection with the electrical connector 2.

[0111] Among them, the two elastic plugs 12 have elastic compressibility, while the two plug walls 116 do not have elastic compressibility. By having the surfaces of the two elastic plugs 12 facing each other elastically press against the electrical connector 2, the circumferential adjustment of the electrical connector 2 during the plugging process can be realized, so as to realize the adjustable installation of the electrical connector 2 and the plug hole 121, which can improve the plugging reliability of the electrical connector 2 and the insert 11. The plugging process is simple and can reduce the difficulty of disassembly and assembly.

[0112] In some embodiments, both plug walls 116 have a first arcuate surface 1161, and the surfaces of the two resilient plugs 12 facing each other are both configured as second arcuate surfaces 122. The axes of the first arcuate surface 1161 and the second arcuate surface 122 coincide and the plug hole 121 has a circular cross-section.

[0113] Specifically, the two plug-in walls 116 each have a first arc-shaped surface 1161 on the side closest to each other, that is, they are plugged into the electrical connector 2 through the first arc-shaped surface 1161, and the two elastic plug-in members 12 each have a second arc-shaped surface 122 on the side closest to each other, that is, they are plugged into the electrical connector 2 through the second arc-shaped surface 122.

[0114] Specifically, the axes of the first arc-shaped surface 1161 and the second arc-shaped surface 122 are aligned, meaning that the centers of the two first arc-shaped surfaces 1161 and the two second arc-shaped surfaces 122 are the same. This results in the plug hole 121 having a circular cross-section. Correspondingly, the electrical connector 2 is at least partially cylindrical, which improves the structural compatibility between the plug hole 121 and the electrical connector 2, thereby enhancing the plug-in reliability between the electrical connector 2 and the plug hole 121.

[0115] With the above configuration, the connection between the first arc-shaped surface 1161 and the second arc-shaped surface 122 can be improved, thereby enhancing the roundness of the insertion hole 121 formed by the first arc-shaped surface 1161 and the second arc-shaped surface 122, making it easier for the surfaces of the two elastic insertion members 12 facing each other and the two insertion walls 116 to be inserted and engaged with the electrical connection plug 2 respectively.

[0116] In some embodiments, the two elastic plug members 12 are distributed opposite to each other along a first direction, so that the two second arc-shaped surfaces 122 can be symmetrically distributed, and the two first arc-shaped surfaces 1161 are symmetrically distributed, which is beneficial for symmetrically pressing the electrical connector 2. The two plug walls 116 can be distributed opposite to each other along a second direction, so that the two first arc-shaped surfaces 1161 are distributed opposite to each other along the second direction, and the two second arc-shaped surfaces 122 are symmetrically distributed, which is beneficial for symmetrical connection of the electrical connector 2. Both the first and second directions can be radially along the insertion base 11, and the first and second directions are perpendicular to each other.

[0117] Each resilient connector 12 includes an inner pressing portion 123 and an outer fixing portion 124 distributed along a first direction. The inner pressing portion 123 and the outer fixing portion 124 are spaced apart and their ends are connected by a connecting portion 125. The inner pressing portion 123 is pressed into the electrical connector 2.

[0118] Specifically, such as Figure 5 As shown, each elastic connector 12 includes an inner pressing part 123 and an outer fixing part 124 distributed radially. The inner pressing part 123 and the outer fixing part 124 are spaced apart in the inner and outer directions, so that an elastic pressing deformation space can be formed between the inner pressing part 123 and the outer fixing part 124. The two ends of the inner pressing part 123 and the two ends of the outer fixing part 124 are connected by a connecting part 125, that is, the connecting part 125 is located between the inner pressing part 123 and the outer fixing part 124. The inner pressing part 123 and the outer fixing part 124 can be connected into one unit through the connecting part 125.

[0119] The inner pressing part 123 is distributed close to the center line of the insertion seat 11, while the outer fixing part 124 is distributed away from the center line of the insertion seat 11. This allows the inner pressing part 123 to be close to the electrical connector 2, facilitating the elastic pressing fit between the inner pressing part 123 and the electrical connector 2. It also allows the outer fixing part 124 to be close to the inner wall of the insertion cavity 114, enabling the outer fixing part 124 to be pressed and connected to the insertion cavity 114 of the insertion seat 11.

[0120] Thus, during actual installation, when the electrical connector 2 is inserted into the socket 121, the electrical connector 2 and the inner pressing parts 123 of the two elastic connectors 12 elastically press against each other, allowing the inner pressing parts 123 to elastically deform in the direction of the outer fixing part 124. In this way, the inner pressing parts 123 and the electrical connector 2 can elastically press against each other radially, which can prevent the electrical connector 2 from coming out of the insertion seat 11 and improve the reliability of the fit between the elastic connectors 12 and the electrical connector 2.

[0121] And such as Figure 5 As shown, an opening groove 127 is provided on the outer fixing part 124. The opening groove 127 extends along the axial direction of the outer fixing part 124 and passes through both ends of the outer fixing part 124. In this way, the opening groove 127 can form a deformation gap, so that the elastic plug 12 can undergo elastic deformation after being subjected to the pressure of the electrical connector 2. The opening groove 127 can prevent the stress in the elastic plug 12 from being excessively concentrated in a certain area, thereby playing a buffering role, avoiding premature fatigue failure of the elastic plug 12 caused by stress concentration, and extending the service life of the elastic plug 12.

[0122] In some embodiments, the electrical connector 2 has a mounting hole 21 at one end away from the insertion seat 11, the mounting hole 21 being used to connect to the fusion reactor blanket or vacuum chamber via a third connector.

[0123] Specifically, such as Figure 3 As shown, by providing an installation hole 21 at the end of the electrical connector 2 away from the insertion seat 11, the installation hole 21 can be positioned close to the fusion reactor blanket or vacuum chamber, facilitating the connection between the installation hole 21 and the fusion reactor blanket or vacuum chamber. Furthermore, the installation hole 21 can be connected to the fusion reactor blanket or vacuum chamber via a third connector, meaning that the electrical connector 2 can be detachably connected to the fusion reactor blanket or vacuum chamber via the third connector. The connection process is simple and convenient.

[0124] In this embodiment, the electrical connector 2 is connected to the fusion reactor blanket. The electrical connector 2 has a mounting hole 21, and correspondingly, the fusion reactor blanket has a connection mating hole. The connection mating hole and the mounting hole 21 are distributed accordingly. The mounting hole 21 can be constructed as a threaded connection hole or a through hole. The third connector can be constructed as a connecting bolt. By threading the connecting bolt through the through hole and the mounting hole 21, the electrical connector 2 and the fusion reactor blanket can be connected by thread. The mounting base 13 is connected to the vacuum chamber. The mounting base 13 has multiple mounting through holes 137, and correspondingly, the inner wall of the vacuum chamber has multiple mounting mating holes. The multiple mounting through holes 137 and the multiple mounting mating holes are distributed one-to-one. Thus, by sequentially threading multiple bolts through the multiple mounting through holes 137 and the multiple mounting mating holes, the mounting base 13 can be connected to the vacuum chamber.

[0125] In this way, the mounting base 13 of the assembled socket assembly 1 is fixed to the inner wall of the vacuum chamber with bolts, and the threaded hole 1171 at the end of the electrical connector plug 2 is fixed to the corresponding position of the shielding block of the fusion reactor blanket by the third connector. When the shielding block is damaged and needs to be disassembled, the electrical connector plug 2 can be inserted or pulled out relative to the insertion seat 11. The operation is simple and convenient.

[0126] It should be noted that, depending on the conductivity requirements, the electrical connection assembly 100 can be used individually or in multiples (two or more). That is, a single shielding block can be equipped with one or more electrical connection assemblies 100 connected to the vacuum chamber.

[0127] The present invention also proposes a fusion device.

[0128] According to an embodiment of the present invention, a fusion device includes a fusion reactor blanket, a vacuum chamber, and an electrical connection assembly 100 of any of the above embodiments. The fusion reactor blanket is connected to the vacuum chamber through the electrical connection assembly 100. The fusion reactor blanket includes a plurality of shielding blocks, and each shielding block can be connected to the vacuum chamber through the electrical connection assembly 100, thereby realizing the connection between the fusion reactor blanket and the vacuum chamber.

[0129] The electrical connection assembly 100 includes a socket assembly 1 and an electrical connection plug 2. The electrical connection plug 2 is engaged with the flexible plug 12, making the connection between the fusion reactor blanket and the insertion base 11 simple and convenient. This direct plug-in installation method ensures that the current transmission connection is normal without the need for disassembly and assembly of screws or other fasteners, which can greatly reduce the disassembly and assembly time in confined working spaces, improve operational convenience and assembly efficiency. The electrical connection plug 2 and the flexible plug 12 have a high degree of tightness, which can improve the installation reliability of the fusion reactor blanket. Furthermore, by allowing the insertion base 11 to float relative to the mounting base 13, the position of the electrical connection plug 2 can float relative to the mounting base 13 along the insertion direction. This enables the electrical connection plug 2 to have a certain range of self-adjustment capability, which can compensate for the cumulative errors generated during the processing and assembly of various parts of the fusion reactor blanket, avoid problems such as repeated installation and secondary processing of parts, greatly reduce the difficulty of disassembly and assembly, improve the versatility of the electrical connection assembly 100, and the connection process is simple and the use effect is good.
