Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to high-voltage connectors and vehicles. Background Technology

[0002] With the development of new energy vehicles, their functional configurations are becoming increasingly diversified. Among these, high-voltage electrical components are becoming more prevalent, including existing systems such as vehicle power supply units, vehicle air conditioning compressors, vehicle PTC heaters, and vehicle-mounted steering systems. These high-voltage electrical components are connected to the battery pack via high-voltage connectors to supply power. For electrical safety, fuses are required in the circuit connecting the high-voltage electrical components and the battery pack to disconnect the electrical connection in case of overload, ensuring the safety of the high-voltage electrical components.

[0003] In existing new energy vehicles, fuses are typically located inside the high-voltage distribution box within the battery pack, or inside the casing of high-voltage electrical appliances. When a fuse blows during use, it needs to be replaced to ensure protection of the high-voltage appliances. For fuses located inside the high-voltage distribution box within the battery pack, replacing the fuse requires disassembling the battery pack; for fuses located inside the casing of high-voltage electrical appliances, replacing the fuse requires disassembling the high-voltage appliances, resulting in lengthy maintenance times and high costs.

[0004] To address the aforementioned issues, the current solution involves housing the fuse within the high-voltage connector. The high-voltage connector includes a base housing and a cover atop the base housing, with a cavity inside the base housing for holding the fuse. For easy disassembly, the cover is secured to the connector with clips, sealing the cavity. When the fuse needs replacement, the clips are released, allowing the cover to be removed and the fuse exposed. This eliminates the need to disassemble the high-voltage appliance or battery pack, reducing maintenance time and costs.

[0005] Existing high-voltage connectors use a latching mechanism for locking the cover, which involves a conventional locking ring and a locking protrusion, both of which are exposed. Therefore, both professional maintenance personnel and ordinary people can easily unlock the connector by manually prying open the locking ring and separating it from the locking protrusion. This ease of unlocking results in poor security.

[0006] Therefore, how to solve or improve the problem of poor safety caused by the fact that the latch used to lock the cover of the high-voltage connector can be unlocked by hand has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, this application provides a high-voltage connector and vehicle to solve or improve the problem that the safety is poor because the latch on the high-voltage connector used to lock the cover can be unlocked by hand.

[0008] In a first aspect, this application provides a high-voltage connector, comprising:

[0009] The shell has a cavity, and the cavity has an opening;

[0010] A fuse is disposed within the cavity, and the fuse is used to connect to the battery pack and the high-voltage electrical appliance, respectively.

[0011] A cover is provided on the opening and seals the opening. One of the housing and the cover is provided with a receiving groove, and a first snap-fit ​​structure is provided in the receiving groove. The other of the housing and the cover is provided with a second snap-fit ​​structure, which is located in the receiving groove and is detachably snapped into the first snap-fit ​​structure.

[0012] Optionally, one of the first snap-fit ​​structure and the second snap-fit ​​structure includes a spring piece and the other includes a protrusion, wherein the first end of the spring piece is a fixed end and the second end is a movable end;

[0013] The spring is engaged with the protrusion under normal conditions, and the spring can undergo elastic deformation under external force to disengage from the protrusion.

[0014] Optionally, the housing includes a first outer shell, a first shielding layer, and a first insulator arranged sequentially from the outside to the inside, wherein the first shielding layer is used to shield electromagnetic interference;

[0015] The cavity is disposed within the insulator, and the cover is adapted to cover the first outer shell and seal the opening.

[0016] Optionally, it also includes:

[0017] An input connector is disposed on the housing and electrically connected to the fuse; the input connector is used for electrical connection to the battery pack.

[0018] An output connector is disposed on the housing and electrically connected to the fuse; the output connector is used to connect to a high-voltage electrical appliance.

[0019] Optionally, the output connector includes a first output connector and a second output connector, and the fuse is connected between the input connector and the first output connector, and between the input connector and the second output connector.

[0020] Optionally, the fuse includes a first fuse and a second fuse, with the first fuse connected between the input connector and the first output connector, and the second fuse connected between the input connector and the second output connector.

[0021] Optionally, the first output connector and the second output connector are oriented in opposite directions;

[0022] Alternatively, the first output connector and the second output connector are oriented perpendicularly.

[0023] Optionally, a sealing ring is provided on the cover, and when the cover is placed on the housing, the sealing ring is pressed between the cover and the housing.

[0024] Optionally, the output connector includes a second housing, a second shielding layer, a second insulator, and a power connection terminal. The second housing, the second shielding layer, and the second insulator are arranged sequentially from the outside to the inside. The power connection piece is disposed inside the second insulator and is energized and connected to the fuse.

[0025] Secondly, this application also provides a vehicle including any of the high-voltage connectors described above.

[0026] This application provides a high-voltage connector, including a housing, a fuse, and a cover. The housing has an open cavity. The fuse can be installed into the cavity through the opening. After the fuse is installed in the cavity, a high-voltage electrical appliance is connected to a battery pack through the fuse inside the housing. The cover, when placed over the opening on the housing, seals the opening, thus enclosing the fuse within the cavity. A receiving groove is provided on one of the housing and the cover, and a second snap-fit ​​structure is provided on the other. A first snap-fit ​​structure is provided in the receiving groove, and a second snap-fit ​​structure is provided on the housing. After the cover is placed over the opening, the second snap-fit ​​structure enters the receiving groove and detachably snaps into the first snap-fit ​​structure. When the fuse blows, it needs to be replaced. In this case, the first snap-fit ​​structure must first be detached from the second snap-fit ​​structure to release the snap-fit. Then, the cover can be removed from the housing, exposing the opening, allowing the fuse to be replaced. After removing the discarded fuse and replacing it with a new one, the cover is placed over the opening on the housing. At this point, the second snap-fit ​​structure enters the receiving groove and snaps into the first snap-fit ​​structure, ensuring that the cover is fixedly snapped into the housing and sealing the opening.

[0027] Because the first and second locking structures are interlocked in the receiving groove, it increases the difficulty of manually removing the first and second locking structures. Tools are required to remove the first and second locking structures, thereby increasing safety and preventing non-professional maintenance personnel from accidentally removing the cover and damaging the fuse.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The following is combined Figures 1 to 7 This describes an embodiment of the present application.

[0040] According to embodiments of this application, in one aspect, a high-voltage connector is provided, such as... Figures 1 to 7 As shown, the device includes a housing 1, a fuse 2, and a cover 3. A cavity 4 is provided inside the housing 1, with an opening. The fuse 2 can be inserted into the cavity 4 through the opening for installation. A threaded mounting hole is provided inside the cavity 4; after the fuse 2 is inserted into the cavity 4, it is installed in the cavity 4 using screws. An input terminal and an output terminal are provided inside the cavity 4. After the fuse 2 is installed in the cavity 4, its first end is electrically connected to the input terminal, and its second end is electrically connected to the output terminal.

[0041] After the housing 1 is connected to the battery pack, the input connector is electrically connected to the battery pack. An output connector is also provided inside the housing 1; when a high-voltage electrical appliance is connected to the housing 1 via a line, the output connector is electrically connected to the high-voltage electrical appliance via the line. After the fuse 2 is detachably installed in the cavity 4, the first end of the fuse 2 is energized to the input connector, and the second end of the fuse 2 is energized to the output connector. Thus, the high-voltage electrical appliance is energized to the battery pack through the fuse 2 inside the housing.

[0042] After the cover 3 is placed over the opening on the housing 1, it can seal the opening, that is, seal the fuse 2 inside the cavity 4. A receiving groove 6 is provided on one of the housing 1 and the cover 3, and a second snap-fit ​​structure is provided on the other. A first snap-fit ​​structure is provided in the receiving groove 6, and a second snap-fit ​​structure is provided on the housing 1. After the cover 3 is placed over the opening, the second snap-fit ​​structure enters the receiving groove 6 and is detachably snapped into place with the first snap-fit ​​structure.

[0043] After fuse 2 blows, it needs to be replaced. To do this, the first snap-fit ​​structure must be detached from the second snap-fit ​​structure to cancel the snap-fit. Then, the cover 3 can be removed from the housing 1, exposing the opening, allowing for the replacement of fuse 2. After removing the discarded fuse 2 and replacing it with a new one, the cover 3 is finally placed over the opening on the housing 1. At this point, the second snap-fit ​​structure enters the receiving groove 6 and snaps into the first snap-fit ​​structure, ensuring the cover 3 is securely snapped onto the housing 1 and seals the opening.

[0044] Because the first and second locking structures are interlocked within the receiving groove 6, it increases the difficulty of manually disengaging them. Tools are required to disengage them, thus increasing safety and preventing unauthorized personnel from accidentally removing the cover 3 and damaging the fuse 2. It also prevents accidental disengagement of the first and second locking structures due to impacts from other objects.

[0045] As an optional embodiment, such as Figure 2 and Figure 6 As shown, one of the first and second snap-fit ​​structures includes a spring piece 5, and the other includes a protrusion 7. The first end of the spring piece 5 is a fixed end, and the second end is a movable end. A snap-fit ​​block 8 is provided at the movable end of the spring piece 5.

[0046] Under normal conditions, the spring piece 5 is engaged with the locking block 8 and the protrusion 7. Applying external force to the spring piece 5 can cause it to undergo elastic deformation, causing the locking block 8 and the protrusion 7 to disengage.

[0047] Specifically, in the first example, such as Figure 2 and Figure 6 As shown, the receiving groove 6 is formed on the cover 3. The first snap-fit ​​structure includes a spring piece 5, the fixed end of which is connected to the inner wall of the receiving groove 6, and the movable end of which is located inside the receiving groove 6. The second snap-fit ​​structure includes a protrusion 7, which protrudes from the outer wall of the housing 1.

[0048] When the cover 3 is not on the housing 1, the spring piece 5 is in its normal state. During the process of placing the cover 3 on the housing 1, the protrusion 7 extends into the receiving groove 6 and continues to extend in the direction of extension. At this time, the locking block 8 is located in the direction of extension of the protrusion 7. As the protrusion 7 continues to extend, the side of the protrusion 7 closest to the direction of extension abuts against the first side of the locking block 8 and pushes the spring piece 5, causing it to gradually deform. Until the cover 3 is completely placed on the housing 1 and the opening is sealed, the protrusion 7 just moves away from the locking block 8, the spring piece 5 returns to its normal state, and the second side of the locking block 8 abuts against the side of the protrusion 7 opposite to the direction of extension, forming a locking action. This prevents the protrusion 7 from dislodging from the receiving groove 6, thus securing the cover 3.

[0049] When it is necessary to release the card, insert the tool into the receiving groove 6 and use the tool to move the spring 5 to deform it, so that the locking block 8 is separated from the protrusion 7, and the protrusion 7 can be withdrawn from the receiving groove 6 in the opposite direction of its insertion, so that the cover 3 can be separated from the shell 1.

[0050] In the second embodiment, the receiving groove 6 is formed on the cover 3, and the first snap-fit ​​structure includes a protrusion 7, which protrudes from the outer wall of the housing 1. The second snap-fit ​​structure includes a spring piece 5, the fixed end of which is connected to the outer wall of the housing 1.

[0051] When the cover 3 is not on the housing 1, the spring piece 5 is in its normal state. During the process of placing the cover 3 on the housing 1, the spring piece 5 extends into the receiving groove 6 and continues to extend in the direction of extension. At this time, the protrusion 7 is located in the direction of extension of the locking block 8. As the locking block 8 continues to extend, the side of the locking block 8 closest to the direction of extension abuts against the first side of the protrusion 7 and pushes the spring piece 5, causing it to gradually deform. Until the cover 3 is completely placed on the housing 1 and the opening is sealed, the locking block 8 just separates from the protrusion 7, the spring piece 5 springs back to its normal state, and the side of the locking block 8 opposite to the direction of extension abuts against the second side of the protrusion 7 to form a lock. This prevents the spring piece 5 from dislodging from the receiving groove 6, thus securing the cover 3.

[0052] When it is necessary to release the card, insert the tool into the receiving groove 6 and use the tool to move the spring 5 to deform it, so that the locking block 8 is separated from the protrusion 7, and the spring 5 can be withdrawn from the receiving groove 6 in the opposite direction of its insertion, so that the cover 3 can be separated from the shell 1.

[0053] In the third embodiment, the receiving groove 6 is formed on the housing 1. The first snap-fit ​​structure includes a spring piece 5, the fixed end of which is connected to the inner wall of the receiving groove 6, and the movable end of which is located inside the receiving groove 6. The second snap-fit ​​structure includes a protrusion 7, which protrudes from the outer wall of the cover 3.

[0054] When the cover 3 is not on the housing 1, the spring piece 5 is in its normal state. During the process of placing the cover 3 on the housing 1, the protrusion 7 extends into the receiving groove 6 and continues to extend in the direction of extension. At this time, the locking block 8 is located in the direction of extension of the protrusion 7. As the protrusion 7 continues to extend, the side of the protrusion 7 closest to the direction of extension abuts against the first side of the locking block 8 and pushes the spring piece 5, causing it to gradually deform. Until the cover 3 is completely placed on the housing 1 and the opening is sealed, the protrusion 7 just moves away from the locking block 8, the spring piece 5 returns to its normal state, and the second side of the locking block 8 abuts against the side of the protrusion 7 opposite to the direction of extension, forming a locking action. This prevents the protrusion 7 from dislodging from the receiving groove 6, thus securing the cover 3.

[0055] When it is necessary to release the card, insert the tool into the receiving groove 6 and use the tool to move the spring 5 to deform it, so that the locking block 8 is separated from the protrusion 7, and the protrusion 7 can be withdrawn from the receiving groove 6 in the opposite direction of its insertion, so that the cover 3 can be separated from the shell 1.

[0056] In the fourth embodiment, the receiving groove 6 is formed on the housing 1, and the first snap-fit ​​structure includes a protrusion 7, which protrudes from the outer wall of the cover 3. The second snap-fit ​​structure includes a spring piece 5, the fixed end of which is connected to the outer wall of the housing 1.

[0057] When the cover 3 is not on the housing 1, the spring piece 5 is in its normal state. During the process of placing the cover 3 on the housing 1, the spring piece 5 extends into the receiving groove 6 and continues to extend in the direction of extension. At this time, the protrusion 7 is located in the direction of extension of the locking block 8. As the locking block 8 continues to extend, the side of the locking block 8 closest to the direction of extension abuts against the first side of the protrusion 7 and pushes the spring piece 5, causing it to gradually deform. Until the cover 3 is completely placed on the housing 1 and the opening is sealed, the locking block 8 just separates from the protrusion 7, the spring piece 5 springs back to its normal state, and the side of the locking block 8 opposite to the direction of extension abuts against the second side of the protrusion 7 to form a lock. This prevents the spring piece 5 from dislodging from the receiving groove 6, thus securing the cover 3.

[0058] When it is necessary to release the card, insert the tool into the receiving groove 6 and use the tool to move the spring 5 to deform it, so that the locking block 8 is separated from the protrusion 7, and the spring 5 can be withdrawn from the receiving groove 6 in the opposite direction of its insertion, so that the cover 3 can be separated from the shell 1.

[0059] In some other embodiments, such as Figure 6 As shown, a first inclined surface 9 is provided on the side of the protrusion 7 opposite to the point where it engages with the locking block 8. After the locking block 8 abuts against the first inclined surface 9 on the protrusion 7, the locking block 8 slides along the first inclined surface 9, thereby causing the elastic piece 5 to deform elastically. This prevents jamming between the locking block 8 and the protrusion 7.

[0060] Alternatively, a second inclined surface 10 can be provided on the side of the latching part opposite to the latching point of the protrusion 7. After the protrusion 7 abuts against the second inclined surface 10 on the latching block 8, the protrusion 7 slides along the second inclined surface 10, thereby causing the spring piece 5 to undergo elastic deformation. This prevents jamming between the latching block 8 and the protrusion 7.

[0061] It is worth noting that the first inclined plane 9 and the second inclined plane 10 can be set simultaneously.

[0062] In another embodiment, such as Figures 1 to 7 As shown, two first-type snap-fit ​​components are provided, one on each side, and two second-type snap-fit ​​components are also provided, one on each side. The first and second snap-fit ​​components are detachably snapped together to form a first snap-fit ​​structure, and the second and third snap-fit ​​components are detachably snapped together to form a second snap-fit ​​structure. These two sets of snap-fit ​​structures simultaneously engage to secure the cover 3, resulting in a more stable connection.

[0063] It is worth noting that multiple first and second connectors can be provided on each side, with each first connector corresponding to and detachably connected to a second connector.

[0064] As an optional embodiment, such as Figure 7As shown, the housing 1 includes a first outer shell 101, a first shielding layer 102, and a first insulator 103. The first outer shell 101 covers the outside of the first shielding layer 102, and the first shielding layer 102 covers the outside of the first insulator 103, such that the first outer shell 101, the first shielding layer 102, and the first insulator 103 are arranged sequentially from the outside in. A cavity 4 is formed in the first insulator 103. The first shielding layer 102 is made of metal. A cover 3 is placed on the first outer shell 101 and seals the opening of the cavity 4.

[0065] With this configuration, the presence of the first shielding layer 102 made of metal not only prevents external electromagnetic interference to the fuse 2, the input terminal and the output terminal, but also prevents electromagnetic interference to the outside world.

[0066] As an optional embodiment, the high-voltage connector further includes an input connector 11 and an output connector 12. The input connector 11 is connected to the bottom of the housing 1 and electrically connected to the input contact plate. The input connector 11 is inserted into a pre-set socket on the battery pack, thereby electrically connecting the input connector 11 to the battery pack. The output connector 12 is connected to the side wall of the housing 1 and electrically connected to the output contact plate. The power supply harness of the high-voltage appliance is plugged into the output connector 12, thereby electrically connecting the high-voltage appliance to the output connector 12.

[0067] After this connection, the high-voltage connector is electrically connected to the battery pack through fuse 2, thereby providing power to the high-voltage connector. At the same time, fuse 2 provides protection between the high-voltage connector and the battery pack.

[0068] In a further embodiment, such as Figures 1 to 5 As shown, the output connector 12 includes a first output connector and a second output connector. Both the first output connector and the second output connector are connected to the fuse 2, so that both the first output connector and the second output connector are electrically connected to the input connector 11 through the fuse 2.

[0069] In this way, two different high-voltage electrical appliances can be connected to the first and second output terminals respectively via wiring harnesses, enabling simultaneous power supply to both high-voltage electrical appliances. Furthermore, both high-voltage electrical appliances are electrically connected to the battery pack via fuse 2, ensuring that both appliances are protected by fuse 2.

[0070] Furthermore, fuse 2 includes a first fuse and a second fuse. Both the first fuse and the second fuse are installed in the receiving slot 6. The first ends of the first fuse and the second fuse are electrically connected to the input contact piece, and the second end of the first fuse is electrically connected to the first output connector through the first output contact piece. The second end of the second fuse is electrically connected to the second output connector through the second output contact piece.

[0071] In this way, two different high-voltage electrical appliances are connected to the first and second output terminals respectively via wiring harnesses. One high-voltage electrical appliance is electrically connected to the battery pack through the first fuse, and the other high-voltage electrical appliance is electrically connected to the battery pack through the second fuse. If one of the first and second fuses blows, the other will still function to protect the connected high-voltage electrical appliance.

[0072] It is worth noting that the output connector 12 may also include a third output connector, or more output connectors 12. Correspondingly, the fuse 2 may include a third fuse, or more fuses. Each output connector 12 is electrically connected to each fuse 2 in a one-to-one correspondence. This allows for the supply of power and protection to more high-voltage electrical appliances.

[0073] In other embodiments, such as Figures 1 to 5 As shown, the first output connector and the second output connector are oriented in opposite directions. Alternatively, the first output connector and the second output connector are oriented perpendicularly. This arrangement facilitates the routing of the wire harnesses that are plugged into the output connector 12 and avoids interference between the wire harnesses.

[0074] It is worth noting that the orientation of the first and second output connectors can be arranged according to the location of the high-voltage electrical appliances, so as to facilitate the connection between the high-voltage electrical appliances and the output connector 12 and reduce the bending of the wiring harness.

[0075] In an optional embodiment, a sealing groove is provided on the cover 3, and a sealing ring is installed in the sealing groove. In this way, after the cover 3 is placed on the housing 1, the sealing ring is pressed between the cover 3 and the housing 1, thereby achieving a sealing effect between the cover 3 and the housing 1 to achieve an IP68 protection level.

[0076] In an optional embodiment, a sealing groove is provided at the bottom of the housing 1, and a sealing ring is provided in the sealing groove. In this way, after the input connector 11 at the bottom of the housing 1 is inserted into the socket on the battery pack, the sealing ring at the bottom of the housing 1 abuts against the socket, thereby sealing between the housing 1 and the socket to achieve an IP68 protection level.

[0077] In optional embodiments, such as Figure 3As shown, the output connector 12 includes a second housing 1201, a second shielding layer 1202, a second insulator 1203, and a power connection terminal 1204. The second housing 1201 covers the outside of the second shielding layer 1202, and the second shielding layer 1202 covers the outside of the second insulator 1203, such that the second housing 1201, the second shielding layer 1202, and the second insulator 1203 are arranged sequentially from the outside to the inside. The power connection terminal 1204 is disposed inside the second insulator 1203 and connected to the output power connection piece, thereby connecting the power connection terminal 1204 to the second end of the fuse 2. After the high-voltage electrical appliance is plugged into the output connector 12 via a wire harness, the high-voltage electrical appliance is connected to the second end of the fuse 2 sequentially through the power connection terminal 1204 and the output power connection piece. The second shielding layer 1202 is made of metal.

[0078] With this configuration, the presence of the second shielding layer 1202 made of metal not only prevents electromagnetic interference from the external electrical terminals 1204, but also prevents electromagnetic interference from the outside world.

[0079] It is worth noting that a sealing groove can be provided in the output connector 12, and a sealing ring can be installed in the sealing groove. In this way, after the wiring harness used to connect high-voltage electrical appliances is inserted into the output connector 12, the sealing ring abuts against the connector of the wiring harness, thereby sealing the output connector 12 and the connector to achieve the IP68 protection level.

[0080] According to an embodiment of this application, another aspect is that a vehicle is also provided, which includes any of the high-voltage connectors described above. The technical effects brought by this vehicle are the same as those of the high-voltage connector, so they will not be described again.

[0081] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by this application.
