Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-voltage electrical connection technology, specifically a high-voltage connector docking structure with floating compensation function. Background Technology
[0002] In high-voltage electrical systems, connectors serve as core nodes for energy and signal transmission, and their reliability directly impacts the safety and stability of system operation. These connectors typically consist of a socket and a plug, and the precision of their mating is a crucial prerequisite for ensuring efficient power transmission.
[0003] Traditional high-voltage connectors typically employ a rigid design for their mating structure, meaning the plug and socket are positioned relatively fixed, allowing for effective connection only within a very small range of installation errors. However, this design faces numerous challenges in practical applications and has become a significant bottleneck restricting system reliability.
[0004] On the one hand, modern high-voltage systems are rapidly evolving towards modularity. Whether it's the battery swapping mode for new energy vehicle battery packs or the modular rapid repair of industrial equipment, both place rigid demands on connectors for rapid insertion and removal and blind mating. However, traditional rigid connectors require extremely high installation and positioning accuracy. In blind mating scenarios lacking precise guidance, problems such as pin misalignment and misalignment are highly likely to occur. This not only significantly extends equipment maintenance time and reduces operational efficiency but may also cause irreversible structural damage to the connector, directly affecting the subsequent operational stability of the system.
[0005] On the other hand, during equipment assembly, due to objective factors such as deviations in component machining accuracy and inconsistent installation benchmarks, the actual mating positions of connectors often deviate in the X and Y axes. Traditional rigid structures cannot accommodate such errors. If mating is forced, the pins and sockets will bear additional radial stress. This not only significantly increases assembly difficulty and reduces production efficiency, but also accelerates wear of contact parts due to long-term stress concentration, significantly shortening the connector's service life and posing a hidden danger to the safe operation of high-voltage systems.
[0006] To address this, this solution proposes a high-voltage connector mating structure with floating compensation function, aiming to specifically solve the technical pain points of the traditional rigid mating structure. Summary of the Invention
[0007] The purpose of this invention is to provide a high-voltage connector mating structure with floating compensation function to solve the problems mentioned above, such as the need for quick insertion and blind insertion, easy occurrence of pin misalignment and misalignment, difficulty in compatibility with X and Y axis offset errors during assembly, forced mating will generate radial stress, increase assembly difficulty, accelerate contact wear, shorten lifespan, and affect system safety.
[0008] This utility model provides the following technical solution:
[0009] A high-voltage connector mating structure with floating compensation function includes a connector body and a floating compensation device. The connector body includes a plug and a socket. The plug has a pin on its top. The socket has an L-shaped structure and a slot on its inner wall that matches the position of the pin. The floating compensation device is located on the socket. The floating compensation device includes a radial horizontal compensation component that allows the socket to move relative to the plug in a horizontal direction perpendicular to the mating axis, and an axial compensation component that moves along the mating axis. The axial compensation component is located on the radial horizontal compensation component.
[0010] Preferably, the radial horizontal compensation component includes a first support base plate, a first slide rail, a first sliding block, and a radial compensation abutment. The first support base plate is installed on the top of the socket, and first support uprights are installed on the top of both sides of the first support base plate. The first slide rail is installed on the top of the first support base plate, and the first sliding block slides on the first slide rail. The radial compensation abutment is symmetrically installed on the inner wall of the first support uprights on both sides of the first sliding block.
[0011] Preferably, each of the radial compensation abutment components includes a first sleeve, a first spring, a first sliding rod, and a first limiting flange. One end of the first sleeve is connected to the inner wall of the first support plate. The inner walls on both sides of the first sleeve are symmetrically provided with first limiting grooves. One end of the first sliding rod slides inside the first sleeve. The outer walls on both sides of the end of the first sliding rod inside the first sleeve are provided with first sliding protrusions. The first sliding protrusions slide inside the first limiting grooves. The first limiting flange is sleeved on the outer circumferential wall of the first sliding rod near the first sliding block. The first spring is sleeved between the first sleeve and the first limiting flange outside the first sliding rod. One end of the first spring is connected to the outer wall of the end of the first sleeve, and the other end is connected to the outer wall of the first limiting flange.
[0012] Preferably, the axial compensation assembly includes a second support base plate, a second slide rail, a second sliding block, and an axial compensation abutment. The second support base plate is installed on the top of the socket, and second support uprights are installed on the top of both sides of the second support base plate. The second slide rail is installed on the top of the second support base plate, and the second sliding block slides on the second slide rail. The axial compensation abutment is symmetrically installed on the inner wall of the second support uprights on both sides of the second sliding block.
[0013] Preferably, each of the axial compensation abutment components includes a second sleeve, a second spring, a second sliding rod, and a second limiting flange. The two ends of the second sleeve are connected to the inner wall of the second support plate. The inner walls on both sides of the second sleeve are symmetrically provided with second limiting grooves. The two ends of the second sliding rod slide inside the second sleeve. The outer walls on both sides of the end of the second sliding rod inside the second sleeve are provided with second sliding protrusions.

[0014] Preferably, the bottom of the second support base plate is mounted on the top of the first sliding block, and the second support base plate is perpendicular to the first support base plate.
[0015] This utility model has the following beneficial effects:
[0016] 1. Solve the adaptation problem of traditional rigid structures. Through the synergistic effect of radial horizontal compensation components and axial compensation components, it can flexibly compensate for installation errors in the horizontal direction perpendicular to the docking axis and in the front and back directions along the docking axis, respectively. This avoids radial stress caused by forced docking, reduces assembly difficulty and improves efficiency.
[0017] 2. The floating compensation device can achieve automatic alignment adjustment through the cooperation of the slide rail and spring assembly. When there is a misalignment between the plug and the socket, the compensation assembly can guide the pin to accurately insert into the slot through the displacement of the sliding block and the elastic buffer of the spring, effectively avoiding problems such as pin misalignment and misalignment. This not only shortens equipment maintenance time and improves operation and maintenance efficiency, but also prevents irreversible structural damage to the connector caused by hard impact, ensuring the long-term stability of the system.
[0018] 3. Extend connector life and reduce safety hazards. The spring structure reduces wear on contact parts, and the limiting groove and sliding protrusion ensure stable and controllable compensation movement, avoiding excessive displacement and damage to components.
[0019] 4. The structure is simple and practical, adopting a modular design with similar component structures and clear logic, which facilitates production and assembly and meets the needs of modular system development. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see the appendix Figure 1 - Figure 6 As shown, a high-voltage connector mating structure with floating compensation function includes a connector body 1 and a floating compensation device 2. The connector body 1 consists of a plug 11 and a socket 12. The plug 11 has a pin 111 on its top. The socket 12 has an L-shaped structure. The inner wall of the socket 12 has a slot that matches the position of the pin 111. This structural design can provide a basic framework for the mating of the pin 111 and the slot. The L-shaped socket 12 facilitates the installation of the floating compensation device 2 for compensation.
[0029] This application solves the adaptation problem of traditional rigid structures. Through the synergistic effect of radial horizontal compensation component 21 and axial compensation component 22, it can flexibly compensate for installation errors in the horizontal direction perpendicular to the docking axis and in the front-to-back direction along the docking axis, respectively, avoiding radial stress caused by forced docking, reducing assembly difficulty and improving efficiency.
[0030] Please see the appendix Figure 2 - Figure 6 As shown, the floating compensation device 2 is located on the socket 12. The floating compensation device 2 includes a radial horizontal compensation component 21 that can move relative to the plug 11 in a horizontal direction perpendicular to the docking axis, and an axial compensation component 22 that can move in the direction of the docking axis. The axial compensation component 22 is located on the radial horizontal compensation component 21. The floating compensation device 2 can realize multi-directional floating compensation, which greatly improves the flexibility of connector docking.
[0031] The radial horizontal compensation assembly 21 includes a first support base plate 211, a first slide rail 212, a first sliding block 213, and a radial compensation abutment member 214. The first support base plate 211 is installed on the top of the socket 12. First support uprights 215 are installed on the top of both sides of the first support base plate 211. The first slide rail 212 is installed on the top of the first support base plate 211, providing a stable support foundation for the entire radial horizontal compensation assembly 21. The first sliding block 213 slides on the first slide rail 212. The radial compensation abutment member 214 is symmetrically installed on both sides of the first support uprights 215. On the inner wall of plate 215, the cooperation between the slide rail and the sliding block makes the horizontal movement smoother and more stable, reducing the jamming during the movement and ensuring smooth displacement compensation. Each radial compensation abutment 214 includes a first sleeve 216, a first spring 217, a first sliding rod 218, and a first limiting flange 219. One end of the first sleeve 216 is connected to the inner wall of the first support plate 215. The inner walls on both sides of the first sleeve 216 are symmetrically provided with first limiting grooves 230. One end of the first sliding rod 218 slides inside the first sleeve 216. The first sliding rod 218 located inside the first sleeve 216... The sliding rod 218 has first sliding protrusions 231 on both sides of its outer wall. These protrusions slide within the first limiting groove 230. This design limits and guides the movement of the first sliding rod 218, preventing it from shifting during movement. A first limiting flange 219 is fitted onto the outer circumferential wall of the first sliding rod 218 near the first sliding block 213. A first spring 217 is fitted between the first sleeve 216 and the first limiting flange 219 on the outside of the first sliding rod 218. One end of the first spring 217 is connected to the outer wall of the end of the first sleeve 216. One end is connected to the outer wall of the first limiting flange 219. When the connector is subjected to external force, the plug 11 pushes the socket 12 to move. At the same time, the first slide rail 212 moves at the bottom of the first sliding block 213 to compensate. During compensation, it pushes the first sliding rod 218 on one side to move, thereby compressing or stretching the first spring 217 to ensure stable position. When the connector is separated, the elastic force of the spring will generate a reverse restoring force. The two first springs 217 drive the first sliding rod 218 to reset, so that the first sliding block 213 returns to the middle of the first slide rail 212 to prepare for the next compensation.
[0032] The axial compensation assembly 22 includes a second support base plate 221, a second slide rail 222, a second sliding block 223, and an axial compensation abutment 224. The second support base plate 221 is installed on the top of the socket 12. Second support uprights 225 are installed on the top of both sides of the second support base plate 221. The second slide rail 222 is installed on the top of the second support base plate 221. The second sliding block 223 slides on the second slide rail 222. The axial compensation abutment 224 is symmetrically installed on the inner walls of the second support uprights 225 on both sides of the second sliding block 223. The bottom of the second support base plate 221 is installed on the top of the first sliding block 213. The second support base plate 221 is perpendicular to the first support base plate 211. The vertical arrangement allows the axial compensation and radial horizontal compensation to work independently and collaboratively, achieving a reasonable spatial layout. The cooperation between the slide rail and the sliding block ensures smooth axial movement. Axial compensation abutment parts 224 are symmetrically installed on the inner walls of the second support plates 225 on both sides of the second sliding block 223. The symmetrical structure ensures the balance of axial compensation force. Each axial compensation abutment part 224 includes a second sleeve 226, a second spring 227, a second sliding rod 228, and a second limiting flange 229. The two ends of the second sleeve 226 are connected to the inner walls of the second support plates 225. The inner walls on both sides of the second sleeve 226 are symmetrically provided with second limiting grooves 240, which play a good limiting and guiding role. The two ends of the second sliding rod 228 slide inside the second sleeve 226. The outer walls on both sides of the ends of the second sliding rod 228 located inside the second sleeve 226 are provided with second sliding protrusions 241. The second sliding protrusions 241 slide inside the second limiting grooves 240. The second limiting flange... 229 is sleeved on the outer circumferential wall of the second sliding rod 228 near both sides of the second sliding block 223. The second spring 227 is sleeved between the second sleeve 226 and the second limiting flange 229 outside the second sliding rod 228. Two ends of the second spring 227 are connected to the outer wall of the end of the second sleeve 226, and the other two ends are connected to the outer wall of the second limiting flange 229. When the connector is subjected to external force, and there is an axial error in the displacement of the plug 11 pushing the socket 12, the second slide rail 222 moves at the bottom of the second sliding block 223 to compensate, causing one side of the second spring 227 to deform. When the connector is separated, the compensating deformation force of the second spring 227 disappears, and the two second springs 227 drive the second sliding rod 228 to reset, so that the second sliding block 223 returns to the middle of the second slide rail 222, preparing for the next compensation.
[0033] Workflow: When the plug 11 and socket 12 are mated, if there is an installation error, the floating compensation device 2 will activate the corresponding compensation mechanism. If there is a horizontal error perpendicular to the mating axis, the radial horizontal compensation component 21 will start working, and the plug 11 will push the socket 12 to move. At this time, the first slide rail 212 will slide at the bottom of the first sliding block 213. During the displacement, it will push the first sliding rod 218 on one side to move. The first sliding protrusion 231 at the end of the first sliding rod 218 will slide along the first limiting slide groove 230 in the first sleeve 216 to ensure the accuracy of the movement direction. At the same time, the first limiting flange 219 on the first sliding rod 218 will compress or stretch the first spring 217. The elastic force of the first spring 217 will form a reverse compensation force, so that the socket 12 can adapt to the horizontal error and ensure that the pin 111 can be accurately aligned with the slot in the socket 12, avoiding radial stress caused by forced mating.
[0034] If an error exists along the docking axis, the axial compensation component 22 activates, causing the plug 11 to push the socket 12 to generate axial displacement. The second slide rail 222 slides at the bottom of the second sliding block 223, which causes the second sliding rod 228 on one side to move. The second sliding protrusion 241 at its end slides along the second limiting groove 240 inside the second sleeve 226, ensuring the stability of the axial movement. At the same time, the second limiting flange 229 on the second sliding rod 228 causes the second spring 227 on one side to deform. The elastic force of the second spring 227 compensates for the axial error, further ensuring the smooth docking of the pin 111 and the socket.
[0035] Since the axial compensation component 22 is located on the radial horizontal compensation component 21, and the second support base plate 221 is perpendicular to the first support base plate 211, the two compensation components can work together to cope with both horizontal and axial errors, greatly improving the flexibility and accuracy of docking.
[0036] When the connector body 1 is separated, the external force disappears, and each compensation component begins to reset. In the radial horizontal compensation component 21, the first spring 217, which was compressed or stretched, recovers its deformation. Its elastic force drives the first sliding rod 218 to move, and the first sliding protrusion 231 resets along the first limiting groove 230, thereby causing the first sliding block 213 to slide on the first slide rail 212 and finally return to the middle of the first slide rail 212, preparing for the compensation of the next docking.
[0037] In the axial compensation assembly 22, the deformed second spring 227 also recovers its deformation, driving the second sliding rod 228 to move. The second sliding protrusion 241 resets along the second limiting groove 240, causing the second sliding block 223 to slide on the second slide rail 222 and return to the center, waiting for the next compensation operation.
[0038] The high-voltage connector docking structure with floating compensation function of this application can flexibly cope with various errors in the docking process, ensuring the reliability and efficiency of docking, and automatically reset after separation to ensure the normal operation of subsequent docking.

[0040] The above description is only a preferred embodiment of the present utility model.
