Description

Technical Field

[0002] A high-voltage box is a core power management device used in high-voltage circuit systems. Its main functions are to centrally distribute high-voltage electrical energy, provide safety protection and monitor its status. It is a hub connecting high-voltage power sources and loads and is an indispensable core device in high-voltage systems in the fields of new energy, energy storage and industry.

[0003] A high-voltage box with anti-misoperation wiring ports is a power device that integrates high-voltage power distribution, circuit protection and anti-misoperation functions. It is used in new energy vehicles, energy storage systems and industrial high-voltage circuit scenarios. Its core is to achieve physical isolation and operation restriction of high-voltage live parts by designing a special mechanical structure at the wiring port.

[0004] Early high-voltage boxes mainly consisted of a housing and terminals. The housing provided basic installation space, while the terminals were directly exposed. Because of the exposed terminals, personnel could accidentally touch them and get electric shocks. Non-dedicated plugs could be inserted into the terminals at will, causing short circuits. To solve these problems, existing high-voltage boxes added baffles to achieve a shielding effect and increased the stability of the baffles with clips. However, in actual use, the existing devices cannot guarantee connection stability when plugs are inserted into the terminals, and there is a risk of poor contact causing arcing and short circuits, which cannot meet the needs of users.

The rear ends of the two connecting rods are fixedly connected to sliding rods. The bottom of the two sliding rods are fixedly connected to protective plates. Ventilation openings are provided on the left and right sides of the outer wall of the box. Fixing components are provided on the left and right sides of the front end of the box cover.

Limiting grooves are formed on the left and right sides of the inner walls of the two rotating rings, and multiple limiting rods are engaged with the corresponding limiting grooves. A trigger rod is fixedly connected to the left side of the outer wall of the two rotating rings. Touch switches are provided on the top of the left and right sides of the front end of the fixed plate.

[0012] As a further description of the above technical solution:

[0013] The fixing component includes two fixing blocks. A spring is fixedly connected to one end of the inner wall of each fixing block. A locking block is fixedly connected to the other end of each spring. A sliding rod is fixedly connected to the upper and lower sides of each locking block. The two sliding rods are slidably connected to the inner wall of the corresponding fixing block. Fixing holes are provided at the front ends of the left and right sides of the outer wall of the box. Fixing holes are provided at the top ends of the left and right sides of the outer wall of the box. One end of each locking block engages with the corresponding fixing hole.

[0014] As a further description of the above technical solution:

At this time, the rotating ring is locked and cannot rotate. When the connector is fully inserted, the second spring resets and pushes the balls into the corresponding groove of the connector. The limiting rod disengages from the limiting groove along with the balls. Rotating the rotating ring causes the trigger rod to contact the touch switch, and the high-voltage box starts working. At the same time, the balls lock the connector because they cannot retract, preventing the connector from accidentally falling off during operation and ensuring connection stability.

[0024] 2. In this utility model, after pulling the lid forward, the lid is rotated 90 degrees around the connection between the right-angle rod and the connecting rod. Then, the lid is pushed backward to the top of the box. The movement of the lid transmits the force to the sliding rod through the connecting rod. The sliding rod slides backward along the groove, simultaneously moving the protective plate backward, so that the ventilation openings on both sides of the box are fully exposed, thus achieving internal heat dissipation.

[0033] 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.

[0034] Reference Figure 4 and Figure 5 An embodiment of this utility model is provided: a high-voltage box with an anti-accidental contact wiring port, including a box body 1, a fixing plate 2 fixedly connected to the front side of the inner wall of the box body 1, a connecting mechanism 3 provided on the front side of the fixing plate 2, and a protective mechanism 4 provided on the inner wall of the box body 1.

[0035] The connecting mechanism 3 includes two interface shells 301, which serve as the connection carrier between the connector and the internal circuitry of the high-voltage box. The rear ends of the two interface shells 301 are fixedly connected to the left and right sides of the front end of the fixing plate 2, respectively. The outer walls of both interface shells 301 are connected to housings 302 on their left and right sides. The housings 302 provide installation space for the ball bearings 304, springs 303, and limiting rods 305. Ball bearings 304 are slidably connected to one side of the inner wall of each housing 302. The ball bearings 304 slide radially along the housing 302. When the connector is inserted, the ball bearings 304 are compressed and retract into the housing 302, triggering the subsequent action of the limiting rods 305. After the connector is fully inserted, the ball bearings 304... 4. Under the action of spring 2 303, the ball 304 is inserted into the groove on the outer wall of the connector. One end of each ball 304 is fixedly connected to spring 2 303. Spring 2 303 resets and pushes the ball 304 into the groove of the connector. The other ends of multiple springs are fixedly connected to one side of the inner wall of the corresponding housing 302. One side of each ball 304 is fixedly connected to a limit rod 305. The limit rod 305 controls whether the rotating ring 3061 can rotate by engaging and disengaging with the limit groove 3062 of the rotating ring 3061. One end of each limit rod 305 passes through one side of the inner wall of the corresponding housing 302. A switch assembly 306 is provided on the rear side of each of the two interface housings 301.

[0036] The switch assembly 306 includes two rotating rings 3061. The rotating rings 3061 control the working state of the high voltage box by rotating. The rear ends of the two rotating rings 3061 are rotatably connected to the left and right sides of the front end of the fixed plate 2, respectively. Limiting grooves 3062 are opened on the left and right sides of the inner wall of the two rotating rings 3061. When the limiting rod 305 is engaged, the rotating ring 3061 is locked. After the limiting rod 305 is disengaged, the rotating ring 3061 can rotate. Multiple limiting rods 305 are engaged with the corresponding limiting grooves 3062. A trigger rod 3063 is fixedly connected to the left side of the outer wall of the two rotating rings 3061. A touch switch 3064 is provided on the top of the left and right sides of the front end of the fixed plate 2. When the rotating ring 3061 rotates to a preset angle, the trigger rod 3063 contacts the touch switch 3064 to transmit a signal.

[0037] The top of each of the two interface shells 301 is connected to a guide shell 13. The front ends of both the interface shells 301 and the guide shell 13 are chamfered. When the connector is inserted, it is guided by the bevel to enter the connecting shell at a preset angle to correct the insertion deviation. The chamfering at the front end reduces the friction between the connector and the edge of the guide shell 13 and reduces the insertion resistance.

[0038] Specifically, when using the high-voltage box and inserting the connector into the interface housing 301, the guide housing 13 uses its structure to limit the insertion angle of the connector. Simultaneously, the chamfered design of the front ends of the interface housing 301 and guide housing 13 reduces insertion deviation. During insertion, the connector squeezes the balls 304 on both sides, causing the balls 304 to contract inwards into the housing 302. The second spring 303 deforms under pressure, which in turn drives the limiting rod 305 to move synchronously and engage with the limiting groove 3062 of the rotating ring 3061. At this time, the rotating ring 3061 is locked and cannot rotate, preventing accidental triggering of the working state when the connector is not fully inserted, and preventing the risk of arcing or short circuit due to poor contact. When the connector is fully inserted, the second spring 303 returns to its original position, pushing the balls 304 into the corresponding grooves of the connector, and the limiting rod 305... 05. As the ball bearing 304 disengages from the limiting groove 3062, the rotating ring 3061 unlocks and can rotate. Rotating the rotating ring 3061 causes the trigger rod 3063 to contact the touch switch 3064, and the high-voltage box starts working. At the same time, the inner wall of the rotating ring 3061 adheres to the limiting rod 305, restricting its movement. The ball bearing 304 cannot retract and locks the connector, preventing the connector from accidentally falling off during operation, thus ensuring the stability of the connection. After the operation is completed, the rotating ring 3061 must be rotated first to disengage the trigger rod 3063 from the touch switch 3064 and deactivate the working state. At this time, the inner wall of the rotating ring 3061 separates from the limiting rod 305. Applying external force can cause the ball bearing 304 to retract again, and the connector can be pulled out smoothly, avoiding the safety hazards caused by misinsertion, incomplete connection, and dislodgement during operation of the existing interface.

[0039] Reference Figure 3 , Figure 4 and Figure 6The protective mechanism 4 includes two connecting rods 401, with right-angle rods 402 and sliding rods 404 connected to their ends respectively. These rods are force transmission components. The outer walls of the two connecting rods 401 are slidably connected to the top of the left and right sides of the inner wall of the box 1. The front ends of both connecting rods 401 are rotatably connected to right-angle rods 402. The rotational characteristics at the corners of the right-angle rods 402 allow the lid 403 to rotate 90 degrees around the connection point, achieving a state switch from closed to stored on top of the box 1. The bottom ends of the two right-angle rods 402 are fixedly connected to the same lid 403. When the lid 403 is closed, it completely covers the wiring ports to prevent accidental contact during non-operational states. When rotated to the top, it exposes... The port facilitates wiring operations, and its position change drives the protective plate 405 to move through the connecting rod 401. The rear ends of the two connecting rods 401 are fixedly connected to the sliding rods 404. The sliding rods 404 drive the protective plate 405 to move synchronously through their own linear movement, thereby realizing the opening and closing control of the vent 406. The bottom of the two sliding rods 404 is fixedly connected to the protective plate 405. The protective plate 405 is located inside the vent 406, completely covering the channel to prevent dust and moisture from entering. Ventilation vents 406 are opened on the left and right sides of the outer wall of the box 1. The ventilation vents 406 are air circulation channels for heat dissipation of internal components. Fixing components 407 are provided on the left and right sides of the front end of the box cover 403.

[0040] The fixing component 407 includes two fixing blocks 4071, which serve as structural supports and component positioning. A spring 4072 is fixedly connected to one end of the inner wall of each fixing block 4071. The spring 4072 provides a restoring force through its own elastic deformation. A locking block 4073 is fixedly connected to the other end of each spring 4072. A sliding rod 4076 is fixedly connected to the upper and lower sides of each locking block 4073. The sliding rod 4076 restricts the locking block 4073 to move only in the horizontal direction. Two sliding rods 4076 are slidably connected to the inner wall of the corresponding fixing block 4071. Fixing holes 4074 are provided on the front left and right sides of the outer wall of the box body 1, and fixing holes 4075 are provided on the top left and right sides of the outer wall of the box body 1. One end of the two locking blocks 4073 is engaged with the corresponding fixing hole 4074. By selectively engaging with fixing holes 4074 and 4075, the locking blocks 4073 can lock the lid 403 in both closed and top-folded states.

[0041] The top of the left and right sides of the inner wall of the box 1 is provided with a sliding groove 5. The sliding groove 5 provides a linear motion guide for the sliding rod 404. The two sliding rods 404 are slidably connected to the inner wall of the corresponding sliding groove 5 on opposite sides.

[0042] Specifically, when the high-voltage box is needed, pull the locking blocks 4073 of the two fixing components 407, causing the locking blocks 4073 to stretch the spring 4072 and disengage it from the fixing hole 4074. At this time, the sliding rod 4076 provides guidance for the movement of the locking blocks 4073, thereby releasing the locked state of the box cover 403. After pulling the box cover 403 forward a certain distance, with the rotational connection between the right-angle rod 402 and the connecting rod 401 as the axis, the box cover 403 is rotated ninety degrees. Then, the box cover 403 is pushed backward to the top of the box body 1. At this time, the locking blocks 4073 are released, the spring 4072 returns to its original position, and the locking blocks 4073 engage with the fixing hole 4075, thus fixing the box cover 403 at the top. During the process, the force generated by the movement of the cover 403 is transmitted to the sliding rod 404 through the connecting rod 401. The sliding rod 404 slides backward along the slide groove 5, simultaneously driving the protective plate 405 to move backward, so that the ventilation openings 406 on both sides of the box body 1 are fully exposed to achieve internal heat dissipation. The slide groove 5 guides and limits the sliding rod 404 to ensure the precise movement of the protective plate 405. When the high-pressure box is not in use, the reverse operation is performed to close the cover 403, and the locking block 4073 re-engages with the fixing hole 4074. At the same time, the sliding rod 404 drives the protective plate 405 to move forward, completely blocking the ventilation openings 406 to achieve dust protection. The opening and closing state of the cover 403 changes synchronously with the position of the protective plate 405, realizing the synergistic function of heat dissipation during use and dust protection when idle.

[0043] Reference Figure 1 , Figure 2 and Figure 4 Dustproof mesh 6 is installed on both the left and right sides of the outer wall of the housing 1. During ventilation and heat dissipation, the dustproof mesh 6 filters dust and fibrous impurities from the air, preventing them from entering the housing 1 and adhering to the surface of the high-voltage components. Gaskets 7 are fixedly connected to the outer walls of both dustproof meshes 6. The gaskets 7 distribute the pressure of the screws 8, preventing deformation of the housing 1 surface due to bolt tightening. Screws 8 are threaded to one side of the outer wall of multiple gaskets 7. One end of each screw 8 passes through one side of the corresponding gasket 7 and is threaded to the outer wall of the housing 1. The screws 8 allow for the removal and fixing of the dustproof mesh 6 through threaded connection, ensuring a secure installation. Connecting blocks 9 are fixedly connected to the outer walls of the housing 1. Connecting block 9 transmits the vibration of box 1 to guide rod 10, while restricting box 1 to move only along the direction of guide rod 10. Guide rod 10 is slidably connected to the inner wall of multiple connecting blocks 9. Guide rod 10 limits the vibration direction of box 1 to avoid lateral shaking that could cause internal wiring to loosen or components to collide. Connecting piece 11 is fixedly connected to the bottom of multiple guide rod 10. Spring 3 12 is provided at the bottom of the outer wall of multiple guide rod 10. Spring 3 12 absorbs vibration energy through elastic deformation. The top of multiple spring 3 12 is fixedly connected to the bottom of the corresponding connecting block 9, and the bottom of multiple spring 3 12 is fixedly connected to the top of the corresponding connecting piece 11.

[0044] Specifically, the dustproof net 6 is tightly installed at the ventilation openings 406 on both sides of the box 1 by means of the gasket 7 and screws 8. The dustproof net 6 can filter dust and impurities in the air and prevent them from entering the box 1 and adhering to the electronic components. The screws 8 facilitate the regular disassembly, cleaning or replacement of the dustproof net 6. The box 1 is slidably connected to the guide rod 10 by the connecting blocks 9 around the perimeter. The connecting piece 11 fixed at the bottom of the guide rod 10 is used for rigid connection with the workbench. When the workbench vibrates, the vibration energy is transmitted to the connecting piece 11. At this time, the connecting block 9 slides along the guide rod 10, and the spring 12 absorbs the vibration energy through deformation, reducing the vibration impact transmitted to the box 1.

[0045] Working principle: When using the high-voltage box, the connector needs to be inserted into the interface housing 301. The guide housing 13 limits the insertion angle of the connector through its structure. Combined with the chamfered design of the front end of the interface housing 301 and the guide housing 13, insertion deviation is reduced. During insertion, the connector squeezes the balls 304 on both sides, causing them to contract inwards into the housing 302. The second spring 303 deforms under pressure, driving the limit rod 305 to move synchronously and engage in the limit groove 3062 of the rotating ring 3061. At this time, the rotating ring 3061 is locked and cannot rotate, preventing accidental triggering of the working state when the connector is not fully inserted, and preventing the risk of arcing or short circuit caused by poor contact. When the connector is fully inserted, the second spring 303 resets, pushing the balls 304 into the corresponding slots of the connector. The retaining rod 305 disengages from the retaining groove 3062 along with the ball 304, unlocking the rotating ring 3061 so it can rotate. Rotating the rotating ring 3061 causes the trigger rod 3063 to contact the touch switch 3064, starting the high-voltage box. At the same time, the inner wall of the rotating ring 3061 adheres to the retaining rod 305, restricting its movement. The ball 304 cannot retract and thus locks the connector, preventing accidental dislodgement during operation and ensuring connection stability. After operation, the rotating ring 3061 must be rotated first to disengage the trigger rod 3063 from the touch switch 3064, deactivating the operating state. At this time, the inner wall of the rotating ring 3061 separates from the retaining rod 305, and applying external force can cause the ball 304 to retract again, allowing the connector to be pulled out smoothly.

[0046] Furthermore, when the high-voltage box is needed, by pulling the locking blocks 4073 of the two fixing components 407, the locking blocks 4073 stretch the spring 4072 away from the fixing hole 4074. At this time, the sliding rod 4076 provides motion guidance for the locking blocks 4073, releasing the locking state of the box cover 403. After pulling the box cover 403 forward to a certain distance, the right-angle rod 402 and the connecting rod 401 are rotated together, and the box cover 403 is rotated 90 degrees around the connection point of the right-angle rod 402 and the connecting rod 401. Then, the box cover 403 is pushed backward to the top of the box body 1. At this time, the locking blocks 4073 are released, the spring 4072 returns to its original position, and the locking blocks 4073 and the fixing hole 4074 are locked together. The cover 403 is fixed at the top by engaging 75. During this process, the movement of the cover 403 is transmitted to the sliding rod 404 through the connecting rod 401. The sliding rod 404 slides backward along the slide groove 5, simultaneously moving the protective plate 405 backward, so that the ventilation openings 406 on both sides of the box body 1 are fully exposed to achieve internal heat dissipation. The slide groove 5 guides and limits the sliding rod 404 to ensure the precise movement of the protective plate 405. When the high-pressure box is not needed, the operation is reversed to close the cover 403. The locking block 4073 re-engages with the fixing hole 4074. At the same time, the sliding rod 404 moves the protective plate 405 forward to completely block the ventilation openings 406, achieving dust protection.
