Description

Technical Field

[0001] This application relates to the technical field of connection terminals, and more particularly to a socket connection terminal. Background Technology

[0002] As the core conductive and connecting component of an electrical connector, the performance of the socket directly determines the transmission efficiency, safety, and service life of the entire circuit. Therefore, optimizing its current carrying capacity, contact stability, assembly convenience, and production cost is of great practical significance.

[0003] Existing socket connectors generally use a "fixed elastic contact" structure (such as corrugated springs or helical springs). The contact force is determined by the initial deformation of the elastic element and cannot be dynamically adjusted according to plug wear, temperature changes, or vibration conditions, which can easily lead to poor contact or difficulty in plug insertion and removal. At the same time, the heat dissipation path of the internal / external conductors of traditional terminals is singular, and under high current conditions, excessive temperature rise can easily lead to insulation aging. In addition, the connector is exposed and is easily deformed by external impacts during insertion and removal, affecting its service life. Summary of the Invention

[0004] The purpose of this invention is to provide a socket connection terminal that can solve the problems of existing technologies that cannot meet the requirements of high conductivity and high mechanical strength, as well as the lack of good heat dissipation.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On one hand, a socket connection terminal is provided, comprising:

[0007] An inner conductor having a socket for connecting a plug, the inner conductor comprising:

[0008] The first connecting segment consists of multiple connecting pieces evenly distributed along the axis of the socket; and

[0009] The second connecting section is a tubular structure, with one end used to connect to the connecting piece and the other end connected to a conductive terminal.

[0010] An outer conductor, covering the first connecting segment and the second connecting segment, is a tubular structure. The outer conductor has a first opening at the position of the first connecting segment corresponding to the connecting piece, and an abutment piece for abutting the connecting piece is connected to the first opening.

[0011] A housing is connected to the outer conductor, and the housing and the outer conductor are snap-fitted together.

[0012] An adjustment mechanism is provided on the housing and connected to the abutment piece. The adjustment mechanism is used to drive the abutment piece to move between a first position and a second position.

[0013] When the abutting piece moves from the first position to the second position, the abutting piece drives one end of the connecting piece to deflect towards the axial direction of the insertion hole.

[0014] Preferably, the contact surface of the connecting piece located on one side of the socket is bent, and the closest point of the contact surface to the axis of the socket is located on an arc of the first diameter;

[0015] The inner wall of the second connecting segment of the inner conductor is located on the arc of the second diameter, and the arc of the first diameter and the arc of the second diameter are coaxially arranged.

[0016] The first diameter is smaller than the second diameter.

[0017] Preferably, the contact surface of the connecting piece located on the side inside the socket further includes a guide end face, which extends outward from the axis of the socket.

[0018] Preferably, the abutting piece and the outer conductor are integrally formed, the abutting piece extends from the outer side of the outer conductor toward the axial direction of the socket, and the suspended end of the abutting piece abuts against the connecting piece.

[0019] Preferably, the outer conductor has a protective portion at the suspended end of the connecting piece for protecting the connecting piece;

[0020] The protective part includes multiple protective plates bent towards the axis of the socket, with the convex surfaces of the bent protective plates facing away from the insertion direction of the plug; and

[0021] The suspended end of the abutment piece is located within the protective zone formed by the bending of the protective piece.

[0022] Preferably, it further includes a snap-fit ​​mechanism for connecting the outer conductor and the housing, the snap-fit ​​mechanism comprising:

[0023] A slot is formed inside the housing, and a block is disposed on the outer conductor;

[0024] The outer conductor has a second opening, the locking block is disposed at the second opening, and the locking block and the outer conductor are disposed at an angle, the angle being directed toward the insertion direction of the plug.

[0025] Preferably, the adjustment mechanism includes:

[0026] An adjusting ring, sleeved on the second connecting section of the inner conductor and located in the gap between the outer conductor and the inner conductor, has a rigid adjusting rod fixedly connected to it, the end of which abuts against the outside of the abutment piece; and

[0027] A driving unit is used to drive the adjusting ring to move toward the suspended end of the connecting piece;

[0028] When the adjusting ring moves from the first adjusting position to the second adjusting position on the inner conductor, the force applied by the adjusting rod to the abutment piece increases linearly due to the angle design between the adjusting rod and the axis of the socket.

[0029] Preferably, the driving unit includes:

[0030] An adjusting bolt, perpendicular to the axis of the insertion hole and threadedly connected to the housing, has a spherical end; and

[0031] An adjusting block is integrally formed on the adjusting ring, and a guide surface is provided on the adjusting block;

[0032] The end of the adjusting bolt acts on the guide surface, which is used to convert the first directional force of the adjusting bolt perpendicular to the adjusting ring into a second directional force along the axis of the insertion hole, which can drive the adjusting block to move.

[0033] Preferably, a thermally conductive layer is provided on the outer side of the inner conductor, the thermally conductive layer extending from the first connecting segment to the second connecting segment; and

[0034] The housing is provided with a heat dissipation structure, which is located in the corresponding area of ​​the second connecting section.

[0035] Preferably, the heat dissipation structure includes:

[0036] A heat-conducting ring is attached to the outer conductor, and multiple parallel heat dissipation fins are connected to the heat-conducting ring;

[0037] Multiple heat dissipation cavities are provided inside the housing, and the heat dissipation fins are located inside the heat dissipation cavities;

[0038] A sealing element is provided at the connection between the heat dissipation fins and the heat dissipation cavity for sealing.

[0039] The beneficial effects of this application are as follows:

[0040] 1. The clamping force can be dynamically replenished according to the wear of the connecting piece. When the elasticity of the connecting piece decreases due to long-term insertion and removal, there is no need to replace the terminal. Simply turn the adjusting bolt to drive the connecting piece to shift towards the X-axis and restore tight contact with the plug, fundamentally solving the problem of "wear equals scrap" of traditional terminals.

[0041] 2. The inner conductor is covered with a graphene thermal conductive layer, which, together with the thermal conductive ring and heat dissipation fins attached to the outer conductor, forms a complete heat dissipation path of "heat generation in the inner conductor, conduction in the thermal conductive layer, convergence in the thermal conductive ring, and convection in the fins". Under high current conditions, the terminal temperature rise can be controlled within 45K, avoiding aging of insulating components due to high temperature.

[0042] 3. The angle design between the adjusting rod and the X-axis enables a linear increase in contact force, preventing damage to the connecting piece due to inaccurate force control. The linear force change can be precisely predicted by adjusting the number of rotations of the adjusting bolt. Operators can control the clamping force by the number of rotations without specialized instruments, significantly reducing the technical barrier to adjustment operations.

[0043] 4. The protective zone formed by the protective plates perfectly covers the suspended end of the contact plate, effectively preventing external dust and foreign objects from covering the contact plate. Traditional terminal contact plates are prone to increased pushing resistance due to dust accumulation. In this solution, the contact plate remains in a clean environment, improving the response sensitivity of the adjustment mechanism.

[0044] 5. After the axial and radial positions of the inner and outer conductors are precisely fixed, the electromagnetic shielding range of the outer conductor is completely matched with the conductive path of the inner conductor, which can reduce electromagnetic leakage to a certain extent and further improve electromagnetic compatibility.

[0068] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0069] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0070] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0071] like Figures 1 to 10 As shown, this disclosure provides a socket connection terminal 1, which can be used to improve the current socket terminals that cannot be dynamically adjusted according to plug wear, temperature changes or vibration conditions, which easily leads to poor contact or difficulty in plug insertion and removal, as well as the problem that the heat dissipation path of the internal / external conductors of traditional terminals is single, which easily leads to insulation aging due to excessive temperature rise under high current conditions.

[0072] Specifically, the socket connection terminal 1 provided in this disclosure includes an inner conductor 2, an outer conductor 3, and a housing 4.

[0073] The inner conductor 2 has a socket 21 for connecting a plug. Power is conducted when the plug is inserted into the socket 21. To improve the power transmission efficiency between the inner conductor 2 and the plug, the inner conductor 2 is made of copper. Along the axis of the socket 21, the inner conductor 2 is divided into a first connecting segment 22 and a second connecting segment 23. The axis of the socket 21 is defined as the X-axis, and the direction of the axis of the socket 21 is defined as the X-axis direction. The first connecting segment 22 consists of multiple connecting pieces 221 evenly distributed along the axis of the socket 21, with at least six connecting pieces 221. For example, in one embodiment, eight connecting pieces 221 are provided. The second connecting segment 23 is a tubular structure, with one end connected to the connecting pieces 221 and the other end connected to a conductive terminal 24. The connecting pieces 221 are used to mate with the plug to achieve circuit conduction, while the conductive terminal 24 is used to connect to external lines to achieve power supply.

[0074] The outer conductor 3, made of 6061 aluminum-magnesium alloy, serves as both electromagnetic shielding and structural support for the inner conductor 2. This material allows for lightweight terminals and provides a shielding effectiveness of ≥80dB. It is understood that the use of 6061 aluminum-magnesium alloy for the outer conductor 3 achieves an electromagnetic shielding effectiveness of ≥80dB, preventing external electromagnetic interference from affecting power transmission and making it suitable for applications with high electromagnetic compatibility requirements, such as new energy vehicles and aerospace. Furthermore, it covers the first connecting segment 22 and the second connecting segment 23 of the inner conductor 2, providing physical protection and isolating the conductive structure from dust and minor impacts.

[0075] Specifically, the outer conductor 3 covers the outside of the inner conductor 2 and is snapped into the housing 4. The inner conductor 2 can be fixed by the cooperation between the outer conductor 3 and the housing 4.

[0076] The outer conductor 3 has multiple first openings 31 at positions corresponding to the first connecting segment 22, and each first opening 31 corresponds to a position of the connecting piece 221. Each first opening 31 is connected to an abutment piece 32 for abutting against the connecting piece 221. By providing the abutment piece 32 on the outside of the connecting piece 221, the structural strength of the connecting piece 221 can be effectively improved, thereby ensuring the connection effect between the connecting piece 221 and the plug.

[0077] The housing 4 is connected to the outer conductor 3, and the two are connected by a snap-fit ​​mechanism. Designing the housing 4 and the outer conductor 3 as a snap-fit ​​structure facilitates their assembly and connection.

[0078] It should be noted that the housing 4 is provided with an adjustment mechanism 5, which is connected to the abutment piece 32 and is used to drive the abutment piece 32 to move between the first position 3a and the second position 3b. When the abutment piece 32 moves from the first position 3a to the second position 3b, it can drive one end of the connecting piece 221 to shift in the X-axis direction. Therefore, when the plug and socket 21 are plugged in for a long time and at a high frequency, causing wear on the inner side of the connecting piece 221, and thus making the clamping force of the connecting piece 221 on the plug insufficient, the clamping force of the connecting piece 221 on the plug can be adjusted by the adjustment mechanism 5 to restore a stable connection.

[0079] Understandably, by driving the abutment piece 32 to move through the adjustment mechanism 5 on the housing 4, the connecting piece 221 can be offset towards the axis of the socket 21. When the connector piece 221 wears down and the clamping force decreases due to long-term plugging and unplugging, the clamping force can be replenished by the adjustment mechanism 5, avoiding power failures, overheating and other faults caused by loose contact, and greatly improving the service life and adaptability of the terminal.

[0080] In one embodiment, the contact surface 2211 of the connecting piece 221 near the X-axis is curved, and the closest point of the contact surface 2211 near the X-axis is located on the first diameter arc A; simultaneously, the inner wall of the second connecting section 23 of the inner conductor 2 is located on the second diameter arc B, and the first diameter arc A and the second diameter arc B are coaxially arranged, with the first diameter being smaller than the second diameter. Therefore, when the plug is inserted into the socket 21, the plug body drives the connecting piece 221 to unfold, causing the first diameter to expand towards the second diameter; under the action of the abutment piece 32, the connecting piece 221 can fit tightly against the outer wall of the plug body, ensuring that the plug and the contact surface 2211 form "multi-point surface contact", reducing contact resistance, improving power transmission efficiency, and reducing local temperature rise caused by excessive contact resistance.

[0081] It should be noted that the contact surface 2211 of the connecting piece 221 located on the inner side of the socket 21 is also provided with a guide surface 2212, which extends outward from the X-axis. By providing the guide surface 2212, the plug can be inserted into the socket 21 more smoothly.

[0082] In one embodiment, the abutment piece 32 is integrally formed with the outer conductor 3. The abutment piece 32 extends from the outer side of the outer conductor 3 towards the axial direction of the socket 21, and its suspended end abuts against the connecting piece 221. The abutment piece 32 and the outer conductor 3 are integrally formed, which on the one hand avoids the problems of uneven abutment force and loosening after long-term use caused by gaps in traditional splicing structures, ensuring that the abutment force of the abutment piece 32 against the connecting piece 221 is continuously stable, thereby ensuring that the contact pressure between the connecting piece 221 and the plug is constant and reducing the risk of poor contact; on the other hand, the integral forming eliminates additional assembly processes, which simplifies the production process and improves the overall structural strength of the outer conductor 3, preventing the abutment piece 32 from falling off due to external force or vibration and extending the service life of the terminal.

[0083] At the suspended end of the connecting piece 221, the outer conductor 3 is provided with a protective part 33 for protecting the connecting piece 221. The protective part 33 includes a plurality of protective pieces 331 that are bent toward the axis of the socket 21, and the protruding surface of the bent protective piece 331 faces away from the insertion direction of the plug.

[0084] It is understandable that the suspended end of the contact piece 32 is located within the protective area 332 formed by the bending of the protective piece 331. Therefore, when the plug is inserted into the socket 21, it will first contact the protective part 33, and then enter the socket 21 through the guide surface 2212 of the connecting piece 221. By setting the protective part 33, the plug can be prevented from directly impacting the connecting piece 221, effectively buffering the impact force when the plug is inserted, preventing the connecting piece 221 from deforming and wearing due to frequent impacts, solving the problem of "the connecting piece is easily bent by the plug, resulting in contact failure" in traditional terminals, and significantly extending the service life of the connecting piece 221.

[0085] In addition, the protective part 33 can also protect the contact piece 32: the suspended end of the contact piece 32 is located in the protective area 332 formed by the protective piece 331, which can isolate the influence of external dust, foreign objects or slight collisions on the contact piece 32, ensuring that the contact piece 32 can always act stably on the connecting piece 221, without affecting the subsequent contact force adjustment function, and ensuring the reliability of the terminal for long-term use.

[0086] Furthermore, the outer conductor 3 covers the first connecting segment 22 and the second connecting segment 23 of the inner conductor 2, providing effective protection for the inner conductor 2. The second connecting segment 23 of the inner conductor 2 has at least one connecting port 231, and the outer conductor 3 is connected to a card 34 corresponding to each connecting port 231. The card 34 is stamped onto the outer conductor 3 body by a stamping device and can be snapped into the connecting port 231. By snapping the card 34 into the connecting port 231, both misalignment between the outer conductor 3 and the inner conductor 2 can be prevented, and the stability of their connection can be improved. The outer conductor 3 is snapped into the connection port 231 of the second connecting section 23 of the inner conductor 2 by a stamped card 34. Compared with the traditional "no positioning or bolt positioning" method, firstly, it can accurately limit the radial and axial relative displacement of the inner conductor 2 and the outer conductor 3, avoid the two from shifting under long-term vibration or high current conditions, and ensure the stability of the conductive path of the inner conductor 2 and the accuracy of the electromagnetic shielding range of the outer conductor 3; secondly, no additional fasteners are required, and fixation can be achieved simply by snapping the card 34 into the connection port 231. While simplifying the assembly process, it can also avoid connection failure caused by loosening or corrosion of fasteners, and improve the long-term stability of the connection between the inner and outer conductors.

[0087] Furthermore, the socket connection terminal 1 provided in this disclosure also includes a snap-fit ​​mechanism 6 for connecting the outer conductor 3 and the housing 4. The snap-fit ​​mechanism 6 includes a slot (not shown in the figure) opened inside the housing 4 and a snap-fit ​​block 62 disposed on the outer conductor 3; the outer conductor 3 has a second opening 35, the snap-fit ​​block 62 is disposed at the second opening 35, and the snap-fit ​​block 62 and the outer conductor 3 are arranged at an angle, with the angle direction facing the insertion direction of the plug.

[0088] It is understandable that designing the locking block 62 and the outer conductor 3 at an angle allows the outer conductor 3 to be smoothly inserted into the housing 4; at the same time, the interlocking of the locking block 62 and the slot prevents the outer conductor 3 from easily falling off the housing 4.

[0089] Specifically, when the outer conductor 3 is inserted into the housing 4, the locking block 62 can elastically deform along the included angle direction, smoothly pass through the entrance of the housing 4 and lock into the slot, without the need for tools or forced pressing, greatly reducing assembly difficulty and improving production efficiency; when the outer conductor 3 is subjected to reverse pulling force (such as attempting to detach from the housing 4), since the included angle direction is opposite to the pulling force direction, the locking block 62 will tightly abut against the inner wall of the slot, forming a "reverse locking" effect, avoiding the problem of traditional locking mechanisms easily falling off due to vibration or external force, ensuring that the connection between the housing 4 and the outer conductor 3 is firm for a long time, and ensuring the overall structural stability of the terminal.

[0090] In one embodiment, the adjusting mechanism 5 includes an adjusting ring 51 and a driving unit 52. The adjusting ring 51 is sleeved on the outside of the second connecting section 23 of the inner conductor 2 and is located in the gap between the outer conductor 3 and the inner conductor 2. A rigid adjusting rod 511 is fixedly connected to the adjusting ring 51, and the end of the adjusting rod 511 abuts against the guide block 321 disposed on the outside of the abutment piece 32. Therefore, the rigid adjusting rod 511 can provide a certain support for the abutment piece 32.

[0091] Specifically, the adjusting ring 51 is fitted onto the second connecting section 23 of the inner conductor 2 and is located in the gap between the outer conductor 3 and the inner conductor 2. This design utilizes the existing "inner and outer conductor gap" of the terminal, without increasing the overall volume of the terminal or interfering with the conductivity of the inner conductor 2 and the shielding function of the outer conductor 3, achieving the design goal of "functional integration without occupying extra space" and adapting to the installation requirements of the terminal in various precision equipment such as aerospace electrical connectors and industrial sensor interfaces.

[0092] Furthermore, the drive unit 52 is used to drive the adjusting ring 51 to move towards the suspended end of the connecting piece 221. In the X-axis direction, a first adjusting position 5a and a second adjusting position 5b are defined. When the adjusting ring 51 moves from the first adjusting position 5a to the second adjusting position 5b on the inner conductor 2, the angle design between the adjusting rod 511 and the axis of the socket 21 causes the force applied by the adjusting rod 511 to the abutment piece 32 to increase linearly, thereby driving the abutment piece 32 to drive the connecting piece 221 to shift in the X-axis direction. This linear force change allows operators to predict the clamping force by adjusting the number of rotations of the adjusting bolt 521 (e.g., the force increases by 0.2N for each rotation), reducing the technical threshold of adjustment operations and improving maintenance convenience. Therefore, when the clamping force between the connecting piece 221 and the plug fails due to wear, the clamping force between the connecting piece 221 and the plug can be increased by adjusting the position of the adjusting rod 511, ensuring stable plug insertion.

[0093] Specifically, the adjustment mechanism 5 drives the adjustment ring 51 to move, which in turn drives the rigid adjustment rod 511 to push the contact piece 32, thereby driving the connecting piece 221 to shift in the X-axis direction. When the connecting piece 221 experiences insufficient clamping force with the plug due to wear and tear from long-term insertion and removal, the terminal does not need to be replaced. The clamping force can be replenished simply by adjusting the mechanism 5, fundamentally solving the problem of "wear equals scrap" for traditional terminals and significantly extending the overall service life of the terminals. This design is particularly suitable for scenarios with frequent plug insertion and removal, such as industrial equipment interfaces and vibration conditions, such as wiring harnesses in new energy vehicles. The contact force can be flexibly adjusted according to the actual wear level to ensure that the plug is always stably connected, avoiding malfunctions such as power outages and overheating caused by loose contact.

[0094] Furthermore, the drive unit 52 includes an adjusting bolt 521 and an adjusting block 522. The adjusting bolt 521 is perpendicular to the axis of the insertion hole 21 and threaded onto the housing 4; the end of the adjusting bolt 521 has a spherical structure. The adjusting block 522 is integrally formed on the adjusting ring 51, and a guide surface 5221 is provided on the adjusting block 522. The end of the adjusting bolt 521 acts on the guide surface 5221, which converts the "first directional force" of the adjusting bolt 521 perpendicular to the adjusting ring 51 into a "second directional force" along the axis of the insertion hole 21, capable of driving the adjusting block 522 to move.

[0095] Understandably, the rigid adjusting rod 511 can limit the excessive deformation of the abutment piece 32, ensuring that the abutment piece 32 always maintains effective contact with the connecting piece 221 and maintains the stability of the contact force; at the same time, the fixed connection between the adjusting rod 511 and the adjusting ring 51 can avoid the risk of the adjusting rod 511 shifting or falling off during the adjustment process, and ensure the reliability of the adjusting mechanism 5 for long-term use.

[0096] In one embodiment, a spring 7 can be provided between the housing 4 and the adjusting ring 51. The elastic force of the spring 7 counteracts the driving force applied by the adjusting bolt 521 to the adjusting block 522, thereby ensuring the stability of the adjusting ring 51 during movement. At the same time, the spring 7 can buffer the contact pressure between the spherical structure at the end of the adjusting bolt 521 and the guide surface 5221 of the adjusting block 522, reducing frictional losses between the two.

[0097] In one embodiment, to improve the heat dissipation effect of the socket connection terminal 1 provided in this disclosure during actual use, a heat-conducting layer 8 can be provided on the outer side of the inner conductor 2, and the heat-conducting layer 8 extends from the first connection segment 22 to the second connection segment 23. The heat-conducting layer 8 can be made of graphene. Therefore, the heat generated during the electrical connection between the plug and the inner conductor 2 can be transferred to the heat-conducting layer 8; at the same time, a heat dissipation structure 9 is also provided on the housing 4, which is located in the area corresponding to the second connection segment 23.

[0098] Specifically, the heat dissipation structure 9 includes a heat-conducting ring 91 and multiple heat dissipation fins 92 connected to the heat-conducting ring 91. The heat-conducting ring 91 is attached to the heat-conducting layer 8 of the outer conductor 3, allowing heat from the heat-conducting layer 8 to be transferred to the heat-conducting ring 91. Simultaneously, multiple heat dissipation cavities 41 are formed within the housing 4, and the heat dissipation fins 92 are located within these cavities. The heat dissipation cavities 41 provide independent "heat exchange space" for the heat dissipation fins 92, preventing them from being exposed and deformed by impacts, and guiding directional air convection without affecting heat dissipation efficiency. A sealing element 10 is provided at the connection between the heat dissipation fins 92 and the heat dissipation cavities 41, effectively sealing the connection between the heat dissipation fins 92 and the heat dissipation cavities 41.

[0099] Understandably, the heat-conducting ring 91 is directly attached to the outer conductor 3. Utilizing the high thermal conductivity of the metal material, the heat transferred from the heat-conducting layer 8 to the outer conductor 3 is quickly "converged" to the heat-conducting ring 91, avoiding high resistance loss of heat during conduction due to contact gaps such as air layers. Multiple parallel heat dissipation fins 92 are connected to the heat-conducting ring 91, which can significantly increase the heat dissipation surface area. Moreover, the fins are located in the heat dissipation cavity 41 of the housing 4, which can fully convect and exchange heat with the air, accelerating the dissipation of heat to the external environment.

[0100] Efficient heat dissipation can reduce oxidation and creep of the inner conductor 2 caused by high temperature, and reduce the elasticity decay of components such as connecting piece 221 and abutment piece 32 caused by thermal stress. At the same time, the protection of the sealing component 10 can prevent the core components from being damaged by moisture. It can extend the overall service life of the terminal from the aspects of "reducing thermal damage" and "isolating environmental corrosion", and reduce the maintenance cost of frequent terminal replacement.

[0101] In summary, this disclosure provides a socket connection terminal 1 that can dynamically supplement the clamping force according to the wear degree of the connecting piece 221. When the elasticity of the connecting piece 221 decreases due to long-term insertion and removal, there is no need to replace the terminal. Simply turning the adjusting bolt 521 can drive the connecting piece 221 to shift towards the X-axis, restoring tight contact with the plug, thus fundamentally solving the problem of "wear equals scrap" of traditional terminals.

[0102] The inner conductor 2 is covered with a graphene thermal conductive layer 8, which, together with the outer conductor 3, forms a thermal conductive ring 91 and heat dissipation fins 92, thus constructing a complete heat dissipation path of "heat generation by the inner conductor 2 - conduction by the thermal conductive layer 8 - convergence by the thermal conductive ring 91 - convection by the fins". Under high current conditions, the temperature rise of the socket connection terminal 1 can be controlled within 45K, avoiding aging of the insulating components due to high temperature.

[0103] By adjusting the angle between rod 511 and the X-axis, the contact force increases linearly, preventing damage to the connecting piece 221 caused by inaccurate force control. The linear force change can be accurately predicted by adjusting the number of rotations of bolt 521. Operators can control the clamping force by the number of rotations without the need for professional instruments, greatly reducing the technical threshold for adjustment operations.

[0104] The protective area 332 formed by the protective plate 331 precisely covers the suspended end of the abutment plate 32, which can isolate the abutment plate 32 from external dust and foreign objects. The abutment plate of traditional terminals is prone to increased pushing resistance due to dust accumulation. In this solution, the abutment plate 32 is kept in a clean environment for a long time, and the response sensitivity of the adjustment mechanism 5 can remain stable for a long time.

[0105] After the axial and radial positions of the inner conductor 2 and the outer conductor 3 are precisely fixed by the card 34 and the connector 231, the electromagnetic shielding range of the outer conductor 3 is completely matched with the conductive path of the inner conductor 2, which can reduce electromagnetic leakage by more than 15% and further improve electromagnetic compatibility.

[0106] This solution achieves adjustable contact, efficient heat dissipation, reliable protection, and convenient assembly through structured design, achieving breakthroughs in "ease of use, environmental adaptability, and long-term reliability." It can effectively adapt to high-end scenarios such as new energy, aerospace, and industrial control.
