Description

Technical Field

[0001] This invention relates to the field of terminal technology, specifically to a high-voltage connection terminal for new energy vehicles. Background Technology

[0002] High-voltage connection terminals for new energy vehicles are core conductive connectors in the high-voltage circuit of new energy vehicles. They are mainly used to reliably connect high-voltage components such as power batteries, motors, electronic controls, and OBCs to transmit high-current high-voltage electrical energy. They also have insulation, anti-misinsertion, sealing, vibration resistance, high temperature resistance, and high-voltage interlocking functions to ensure the stability of the high-voltage power supply path of the whole vehicle, prevent leakage and arcing, and take into account driving safety and disassembly and maintenance protection.

[0003] A Chinese patent with publication number CN115101992A discloses a vehicle-mounted power connector, including a socket, a connecting assembly, a safety assembly, and a plug. The socket includes a first insulating shell and a first terminal block. The connecting assembly includes a connecting block, an elastic positioning element, and a cover plate. The connecting block has a through mounting channel. The safety assembly includes a rotating ring and an operating part. One end of the rotating ring has a rotating hole and a clearance groove, and the outer surface of the rotating ring has a positioning groove for connection with the elastic positioning element. The plug includes a second insulating shell, a second terminal block, and a stop part. The second insulating shell and the stop part pass through the rotating hole and the clearance groove into the mounting channel. The second terminal block is electrically connected to the first terminal block. The vehicle-mounted power connector provided by this invention prevents damage to the plug, socket, and cables, avoiding potential safety hazards such as electrical leakage, and also prevents external dust and other impurities from corroding the first terminal block.

[0004] However, existing vehicle-mounted high-voltage power distribution terminals and power distribution units mostly adopt a fixed branch structure. The number of output branches is determined at the factory, and it is impossible to switch the power distribution mode from one input to one to five outputs as needed. When adapting to different models or high and low versions of the same model, it is necessary to redesign parts and open molds. The variety of parts results in high development and inventory costs. It is not convenient to add or remove output branches during production line assembly and debugging or later maintenance. It is difficult to disconnect faulty branches individually. Maintenance operations are cumbersome. The overall structure occupies a large chassis space, which reduces the reliability of the high-voltage power distribution system.

[0005] Therefore, the present invention provides a high-voltage connection terminal for new energy vehicles. Summary of the Invention

[0006] The purpose of this invention is to provide a high-voltage connection terminal for new energy vehicles to solve the problems mentioned in the background art.

[0007] A high-voltage connection terminal for new energy vehicles includes a male connector and a female connector. The male and female connectors are equipped with limit mechanisms and positioning mechanisms for positioning wires. A conductive component is disposed within the female connector. A support block is fixedly disposed within the male connector. Conductive blocks are arrayed above the support block. A conductive copper pillar is fixedly disposed on the side of the conductive block, with one end of the conductive copper pillar extending into the male connector. A connecting groove is fixedly disposed on the side of the conductive block. An insulating block is engaged within the connecting groove. A conductive sheet is fixedly disposed within the insulating block, with its side abutting the connecting groove. A conductive groove is fixedly disposed within the insulating block. A conductive copper strip is disposed within the insulating block, and both the conductive copper strip and the conductive groove are electrically connected to the conductive sheet. An adjustment mechanism for adjusting the position of the insulating block is disposed within the male connector. A support plate is fixedly disposed within the male connector, positioned directly above the insulating block. A conductive plate is fixedly disposed on the support plate, and a current-carrying plate corresponding to the conductive groove is fixedly disposed on the conductive plate, positioned directly above the conductive groove.

[0008] By adopting the above scheme, when using the high-voltage connection terminal for new energy vehicles, the male and female connectors are fixedly connected to the corresponding power lines through positioning mechanisms. After the male and female connectors are connected, they cooperate with the positioning mechanism of the male connector, allowing current to be introduced into the conductive copper strip. The conductive plate fits into the connecting groove, allowing the current to be conducted to the conductive block. After the conductive copper column connects with the conductive cylinder, the current is transmitted to the positioning mechanism of the female connector through the coordinated conduction of the conductive components, and finally delivered to the output power line to complete the power transmission. It is necessary to realize the power distribution ratio of single input and multiple output on the same base, and switch the number of output channels as needed to support input or multiple outputs. Multiple power distribution modes realize power transmission. The position of the corresponding insulating block can be adjusted by adjusting the movement of the adjustment mechanism, so that when the insulating block moves upward, it drives the conductive groove to move synchronously. After the conductive groove engages with the corresponding power board, the conductive plate cooperates to conduct, so that the corresponding conductive block establishes an electrical connection. Then, after the positioning mechanism is connected to the single power line, the power is transmitted through... The wires and copper sheets are fed to the conductive copper strips, and then sequentially pass through the conductive plates, conductive grooves, and energizing plates to establish electrical connections with the corresponding conductive blocks. Power is then transmitted to the female connector via conductive copper pillars and conductive cylinders. Through the coordination of these conductive components, configurable power distribution with single input and multiple outputs can be achieved. The linked conductive structure allows for flexible switching between one input and one to five outputs. Compared to traditional fixed-branch high-voltage power distribution components, this design offers greater versatility; a single unit can be adapted to different vehicle configurations without requiring new molds, reducing component development and inventory costs. During assembly, the linked structure allows for the addition or removal of output branches, facilitating debugging and maintenance. Conversely, adjusting the mechanism lowers the insulating blocks, separating the conductive sheets and connecting grooves to disconnect the corresponding branch. Faulty branches can be isolated without affecting other circuits. The integrated structure reduces space requirements and enhances the safety and reliability of vehicle-mounted high-voltage power distribution.

[0009] Preferably, the conductive component includes a conductive cylinder and a conductive wire. The conductive cylinder corresponding to the conductive copper pillar is fixed inside the female head, and one end of the conductive cylinder extends out of the female head. One end of the conductive wire is connected to the end of the corresponding conductive cylinder.

[0010] By adopting the above scheme, after the conductive copper column is connected to the corresponding conductive cylinder, the male and female connectors are connected. The power is conducted to the conductive cylinder through the conductive copper column, and then transmitted outward through the conductive wire, thereby completing the power distribution.

[0011] Preferably, the limiting mechanism includes a limiting groove, a connecting block, a positioning bolt, a concave groove, and a limiting hole. The limiting groove is symmetrically fixed on the female head, the connecting block is engaged inside the corresponding limiting groove, the positioning bolt is threaded inside the connecting block, the concave groove is symmetrically arranged on the male head, and the limiting hole is arranged inside the concave groove.

[0012] By adopting the above scheme, after the male and female heads are connected, the concave groove and the limiting groove can be aligned. Pushing the connecting block allows it to slide into the concave groove. After the connecting block moves to the predetermined position, the positioning bolt is positioned on one side of the limiting hole. Rotating the positioning bolt allows one end of the positioning bolt to enter the limiting hole, thereby positioning the connecting block and fixing the connection state of the male and female heads.

[0013] Preferably, the positioning mechanism includes a frame, a positioning cylinder, a limiting bolt, and a copper sheet. Both the male and female heads are provided with frames, the positioning cylinder array is arranged on the frame, the limiting bolt is threaded to the positioning cylinder, and the copper sheet corresponding to the positioning cylinder is fixed inside the frame, with the copper sheet located on one side of the positioning cylinder.

[0014] By adopting the above scheme, after the power cord is inserted into the positioning cylinder, the limiting bolt is rotated to fix the power supply. The copper plate is connected to the positioning cylinder, and the power is turned on through the copper plate.

[0015] Preferably, one end of the copper sheet is connected to one end of the corresponding conductive copper strip, and one end of the conductive wire is electrically connected to the corresponding copper sheet.

[0016] By adopting the above scheme, the conductive copper strips and conductive wires are electrically connected to the corresponding copper sheets, and power can be transmitted through the cooperation of the copper sheets.

[0017] Preferably, the adjusting mechanism includes a threaded cylinder, a threaded rod, a limiting ring, and a rotating disk. The threaded cylinder is fixed directly below the insulating block. The threaded rod is threadedly connected inside the threaded cylinder. The limiting ring corresponding to the threaded rod is fixed on the inner wall of the male end, and the threaded rod is engaged with the inner ring of the limiting ring. One end of the threaded rod extends out of the male end, and the rotating disk is fixed on one end of the threaded rod.

[0018] By adopting the above scheme, the threaded rod is driven to rotate by a rotating disk, and the limiting ring is used to support and limit the threaded rod, so that the threaded rod rotates smoothly. When the threaded rod rotates, the position of the threaded cylinder can be adjusted, and the vertical position of the insulating block can be adjusted through the threaded cylinder, thereby adjusting the position of the conductive groove and the conductive sheet.

[0019] Preferably, the adjustment mechanism further includes a guide plate and a guide groove. The guide plate is symmetrically fixed below the insulating block and is located on one side of the threaded cylinder. The guide groove corresponding to the guide plate is fixed inside the male end, and one end of the guide plate passes through the guide groove.

[0020] By adopting the above scheme, when the vertical position of the insulating block is adjusted, the guide plate can be moved synchronously. With the cooperation of the guide groove, the insulating block can be guided, so that the insulating block can move smoothly.

[0021] Preferably, the insulating block has a cavity, the cavity and the conductive groove are concentrically arranged, pressure blocks are symmetrically arranged in the cavity, the pressure blocks have strip grooves, and a limiting strip passes through the strip grooves, with one end of the limiting strip fixedly connected to the inner wall of the cavity.

[0022] By adopting the above scheme, the cavity facilitates the movement of the pressure block. When the pressure block moves, the strip groove and the limiting strip work together to guide the pressure block, allowing it to move smoothly.

[0023] Preferably, a concave plate is provided in the cavity, and the concave plate is fixedly connected to the bottom end of the pressure block. One side of the pressure block is arc-shaped. A through groove is provided in the center of the conductive groove. A driving block is inserted in the through groove and is fixedly connected to the center position of the concave plate. A reset spring is arranged in an array in the cavity, and the end of the reset spring is fixedly connected to the concave plate.

[0024] By adopting the above scheme, after the energized plate enters the conductive groove and contacts the top of the driving block, it applies pressure to the driving block, which will drive the concave plate to move down. The movement of the concave plate will pull the pressure block to move. When the pressure on the top of the driving block is no longer applied, the reset spring will reset the concave plate.

[0025] Preferably, flexible strips are symmetrically arranged in the conductive groove, and the flexible strips are connected to energized blocks, which are conical and located on one side of the pressure block.

[0026] By adopting the above scheme, both the flexible strip and the energized block are made of conductive material. The pressure block moves downward and abuts against the side of the energized block, pushing the energized block to deform. When the energized plate enters the conductive groove, the energized block moves with the action and fits tightly against the side of the energized plate. The energized plate is placed in the conductive groove, which can ensure a reliable energizing contact effect.

[0027] Compared with the prior art, the beneficial effects of the present invention are: 1. The high-voltage connection terminal for new energy vehicles described in this invention allows for adjustment of the position of the corresponding insulating block via an adjustment mechanism. When the insulating block moves upward, it drives the conductive groove to move synchronously. After the conductive groove engages with the corresponding energizing plate, the conductive plate facilitates conduction, establishing an electrical connection between the corresponding conductive block and the power supply. After the positioning mechanism connects to a single power line, the power supply is transmitted to the conductive copper strip via a wire and copper sheet. Then, it is sequentially connected via a conductive sheet, conductive groove, energizing plate, and conductive plate, establishing an electrical connection between the corresponding conductive block and the power supply. Subsequently, the power is transmitted to the female connector via a conductive copper column and conductive cylinder. The configurable power distribution with single input and multiple outputs can be achieved through the cooperation of the conductive components. The linkage conductive structure allows for flexible switching between one input and one to five outputs. Compared to traditional fixed-branch high-voltage power distribution components, this invention offers greater versatility. One main body can adapt to different vehicle configurations without requiring new molds, reducing component development and inventory costs. During assembly, only the linkage structure needs to be operated to add or remove output branches, facilitating debugging and maintenance.

[0028] 2. The new energy vehicle high-voltage connection terminal of the present invention can drive the insulating block to move downward through the action of the adjustment mechanism. The movement of the insulating block causes the conductive sheet to separate from the connection groove, cutting off the corresponding branch. It can disconnect the faulty branch separately without affecting the other circuits. The integrated design reduces space occupation and improves the safety and reliability of vehicle high-voltage power distribution.

[0029] 3. The new energy vehicle high-voltage connection terminal of the present invention, after the energizing plate enters the conductive groove and contacts the top of the driving block, applies pressure to the driving block, which drives the concave plate to move downward. The movement of the concave plate pulls the pressure block to move. The pressure block moves downward and abuts against the side of the energizing block, pushing the energizing block to deform. When the energizing plate enters the conductive groove, the energizing block moves with the action and fits tightly against the side of the energizing plate. The energizing plate is placed in the conductive groove, which can ensure a reliable energizing contact effect. The contact clamping is completed simultaneously in the branch selection action. When switching the power distribution mode of one input corresponding to one to five outputs, each activated branch can obtain a stable and uniform contact pressure, avoiding the problem of large contact resistance difference or local overheating when multiple power distributions are used, and ensuring the reliability of high voltage conduction under multi-branch configuration.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Conductive copper pillars 14 are fixedly disposed on the side of the conductive blocks 16, with one end of the conductive copper pillars 14 extending out of the interior of the male connector 1. A connecting groove 17 is fixedly disposed on the side of the conductive blocks 16, and an insulating block 18 is engaged within the connecting groove 17. An insulating block 18 is fixed within the insulating block 18. A conductive sheet 19 is provided, and the side of the conductive sheet 19 is attached to the connecting groove 17. A conductive groove 27 is fixedly provided inside the insulating block 18. A conductive copper strip 20 is provided inside the insulating block 18, and both the conductive copper strip 20 and the conductive groove 27 are electrically connected to the conductive sheet 19. An adjustment mechanism for adjusting the position of the insulating block 18 is provided inside the male connector 1.

A current-carrying plate 30 corresponding to the conductive groove 27 is fixedly provided on the conductive plate 29, and the current-carrying plate 30 is located directly above the conductive groove 27. When using the high-voltage connection terminal for new energy vehicles, male connector 1 and female connector 2 are fixedly connected to the corresponding power lines through positioning mechanisms. After male connector 1 and female connector 2 are connected, they cooperate with the positioning mechanism of male connector 1, and the current can be introduced into the conductive copper strip 20. The conductive sheet 19 is fitted into the connecting groove 17, so that the current is conducted to the conductive block 16. After the conductive copper column 14 is connected to the conductive cylinder 3, the current is transmitted to the positioning mechanism of female connector 2 through the coordinated conduction of the conductive components, and finally delivered to the output power line to complete the power transmission. The system requires a single-input, multi-output power distribution configuration on the same base, allowing for on-demand switching of output channels. It supports 1-in-1 or 1-in-multiple-output power distribution modes. The position of the corresponding insulating block 18 can be adjusted via a regulating mechanism. When the insulating block 18 moves upward, it drives the conductive groove 27 to move synchronously. After the conductive groove 27 engages with the corresponding energizing plate 30, it conducts electricity through the conductive plate 29, establishing an electrical connection with the corresponding conductive block 16. Then, after the positioning mechanism connects to a single power line, power is transmitted via wires and copper sheets 13 to the conductive copper strip 20. It then sequentially passes through the conductive sheet 19, conductive groove 27, energizing plate 30, and conductive plate 29, establishing an electrical connection with the corresponding conductive block 16. Finally, the power is transmitted through the conductive copper column 14 and conductive cylinder 3. The power is fed to the mother head 2. With the cooperation of the conductive components, a configurable power distribution with single input and multiple outputs can be achieved. The linkage conductive structure allows for flexible switching of the power distribution mode from one input to five outputs. Compared with traditional fixed branch high-voltage power distribution components, it is more versatile. One set of components can be adapted to different vehicle configurations without the need for new molds, reducing the cost of component development and inventory. During the assembly stage, the output branches can be added or removed by operating the linkage structure, which is convenient for debugging and maintenance. Conversely, by adjusting the movement of the mechanism, the insulating block 18 can be moved down. After the insulating block 18 moves down, the conductive piece 19 and the connecting groove 17 are separated, and the corresponding branch can be disconnected. The faulty branch can be cut off separately without affecting the other circuits. The integrated structure reduces the space occupied and improves the safety and reliability of vehicle high-voltage power distribution.

After the conductive copper post 14 is connected to the corresponding conductive cylinder 3, the male head 1 and the female head 2 are connected. The power is conducted to the conductive cylinder 3 through the conductive copper post 14, and then transmitted to the outside through the conductive wire 4, thereby completing the power distribution.

[0035] Furthermore, the limiting mechanism includes a limiting groove 5, a connecting block 6, a positioning bolt 7, a concave groove 8, and a limiting hole 9.

After the male head 1 and female head 2 are connected, the concave groove 8 and the limiting groove 5 can be aligned. Pushing the connecting block 6 allows it to slide into the concave groove 8. After the connecting block 6 moves to the predetermined position, the positioning bolt 7 can be positioned on one side of the limiting hole 9. Rotating the positioning bolt 7 allows one end of the positioning bolt 7 to enter the limiting hole 9, thereby positioning the connecting block 6 and fixing the connection state of the male head 1 and female head 2.

The limiting bolts 12 are threadedly connected to the positioning cylinders 11. The copper sheet 13 corresponding to the positioning cylinder 11 is fixed inside the frame 10, and the copper sheet 13 is located on one side of the positioning cylinder 11. After inserting the power cord into the positioning cylinder 11, rotate the limiting bolt 12 to fix the power supply.

[0038] Furthermore, the adjustment mechanism includes a threaded cylinder 21, a threaded rod 22, a limiting ring 23, and a rotating disk 24. The threaded cylinder 21 is fixed directly below the insulating block 18. The threaded rod 22 is threadedly connected inside the threaded cylinder 21. The limiting ring 23, corresponding to the threaded rod 22, is fixed on the inner wall of the male head 1, and the threaded rod 22 is engaged with the inner ring of the limiting ring 23. One end of the threaded rod 22 extends out of the male head 1, and the rotating disk 24 is fixed on one end of the threaded rod 22. When the position of the insulating block 18 needs to be adjusted, the threaded rod 22 is driven to rotate by the rotating disk 24. The limiting ring 23 is used to support and limit the threaded rod 22, so that the threaded rod 22 rotates smoothly. When the threaded rod 22 rotates, the position of the threaded cylinder 21 can be adjusted. The vertical position of the insulating block 18 can be adjusted through the threaded cylinder 21, and then the positions of the conductive groove 27 and the conductive sheet 19 can be adjusted.

[0039] Furthermore, the adjustment mechanism also includes a guide plate 25 and a guide groove 26. The guide plate 25 is symmetrically fixed below the insulating block 18 and is located on one side of the threaded cylinder 21. The guide groove 26 corresponding to the guide plate 25 is fixed inside the male head 1, and one end of the guide plate 25 passes through the guide groove 26. When adjusting the vertical position of the insulating block 18, the guide plate 25 can move synchronously.

The cavity 31 facilitates the movement of the pressure block 32. When the pressure block 32 moves, the strip groove 33 and the limiting strip 34 cooperate to guide the pressure block 32, so that the pressure block 32 moves smoothly.

[0041] Furthermore, a concave plate 35 is provided inside the cavity 31, and the concave plate 35 is fixedly connected to the bottom end of the pressure block 32. One side of the pressure block 32 is arc-shaped. A through groove 36 is provided in the center of the conductive groove 27.

[0043] Working principle: First, when using the high-voltage connection terminal for new energy vehicles, male connector 1 and female connector 2 are fixedly connected to the corresponding power lines through positioning mechanisms. After male connector 1 and female connector 2 are connected, the concave groove 8 and the limiting groove 5 can be aligned. Pushing the connecting block 6 allows it to slide into the concave groove 8. After the connecting block 6 moves to the predetermined position, the positioning bolt 7 is positioned on one side of the limiting hole 9. Rotating the positioning bolt 7 allows one end of the positioning bolt 7 to enter the limiting hole 9, thereby positioning the connecting block 6 and fixing the connection state of male connector 1 and female connector 2. With the help of the positioning mechanism of male connector 1, current can be introduced into the conductive copper strip 20. The conductive sheet 19 is fitted into the connecting groove 17, allowing the current to be conducted to the conductive block. 16. After the conductive copper column 14 is connected to the conductive cylinder 3, the current is transmitted to the positioning mechanism of the female connector 2 through the coordinated conduction of the conductive components, and finally delivered to the output power line to complete the power transmission. It is necessary to realize the power distribution ratio of single input and multiple output on the same base, and switch the number of output channels as needed to support 1 input to 1 or 1 input to multiple outputs. Multiple power distribution modes realize power transmission. The rotating disk 24 drives the threaded rod 22 to rotate. The limiting ring 23 is used to support and limit the threaded rod 22 to make the threaded rod 22 rotate smoothly. When the threaded rod 22 rotates, the position of the threaded cylinder 21 can be adjusted. The upper and lower positions of the insulating block 18 can be adjusted through the threaded cylinder 21, and then the positions of the conductive groove 27 and the conductive plate 19 can be adjusted. After the conductive groove 27 is engaged with the corresponding energized plate 30, Through the conductive plate 29, the corresponding conductive block 16 is electrically connected. After the positioning mechanism is connected to the single power line, the power is delivered to the conductive copper strip 20 via the wire and copper sheet 13. Then, it is sequentially connected to the conductive plate 29, conductive groove 27, and energizing plate 30, and the corresponding conductive block 16 is electrically connected. Subsequently, the power is delivered to the female connector 2 via the conductive copper column 14 and conductive cylinder 3. Through the cooperation of the conductive components, a configurable power distribution with single input and multiple outputs can be achieved. The linkage conductive structure allows for flexible switching between one input and one to five outputs. Compared with traditional fixed branch high-voltage power distribution components, it has stronger versatility. One set of components can be adapted to different vehicle configurations without the need for new molds, reducing the development of parts. Compared to inventory costs, during the assembly stage, only the linkage structure needs to be operated to add or remove output branches, facilitating debugging and maintenance. Conversely, by adjusting the movement of the mechanism, the insulating block 18 can be moved downwards. After the insulating block 18 moves downwards, the conductive sheet 19 and the connecting groove 17 are separated, and the corresponding branch can be disconnected. The faulty branch can be cut off independently without affecting the other paths. The integrated structure reduces the space occupied and improves the safety and reliability of vehicle-mounted high-voltage power distribution. After the energizing plate 30 enters the conductive groove 27 and contacts the top of the driving block 37, it applies pressure to the driving block 37, which drives the concave plate 35 to move downwards. The movement of the concave plate 35 pulls the pressure block 32 to move. The pressure block 32 moves downwards and abuts against the side of the energizing block 40, pushing the energizing block 40 to deform. When the energizing plate 30 enters the interior of the conductive groove 27...The energizing block 40 moves with the action and fits tightly against the side of the energizing plate 30. The energizing plate 30 is placed inside the conductive groove 27, ensuring reliable energizing contact.
