Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0043] The following reference Figures 1 to 4 This application describes a high-voltage connector for new energy vehicles provided according to some embodiments.

[0044] Example

[0045] A high-voltage connector for new energy vehicles includes a high-voltage socket 1 and a high-voltage plug 2. The high-voltage plug 2 is nested on the outer surface of the high-voltage plug 1 and is snapped into the high-voltage socket 1. The high-voltage socket 1 includes a socket body 11, and the high-voltage plug 2 includes a plug body 21. The socket body 11 has a hollow structure, with a socket opening 111 at one end and a first terminal interface 112 at the end away from the socket opening 111. The plug body 21 has a hollow structure, with a plug opening 211 at one end and a second terminal interface 212 at the end away from the plug opening 211. After the high-voltage socket 1 and the high-voltage plug 2 are nested, the positions of the first terminal interface 112 and the second terminal interface 212 correspond.

[0046] Furthermore, by nesting the high-voltage plug 2 on the outer surface of the high-voltage plug 1, the high-voltage plug 2 and the high-voltage socket 1 are snapped together; this allows the high-voltage plug 2 and the high-voltage socket 1 to be separable, while the snap-fit ​​ensures the stability and reliability of the high-voltage plug 2 nested on the outer surface of the high-voltage plug 1; a first terminal interface 112 is provided at the end of the socket body 11 away from the socket opening 111, the first terminal interface 112 is used for the terminal of the device to be connected to pass through the first terminal interface 112 and enter the socket body 11, and is fixed inside the socket body 11 by the terminal of the device to be connected itself; a second terminal interface 212 is provided at the end of the plug body 21 away from the plug opening 211, the second terminal interface 212 is used for the cable terminal to pass through the second terminal interface 212 and enter the plug body 21, and is fixed inside the plug body 21 by the cable terminal itself; when the second high-voltage plug 2 and the high-voltage socket 1 are nested together, the plug... The cable terminal fixed inside the head body 21 contacts the terminal of the device to be connected inside the socket body 11; after the second crimp socket 1 and the high-voltage plug 2 are nested, the positions of the first terminal interface 112 and the second terminal interface 212 correspond, ensuring the accuracy and reliability of the electrical connection between the terminal of the device to be connected fixed at the first terminal interface 112 and the cable terminal fixed at the second terminal interface 212 after the crimp socket 1 and the high-voltage plug 2 are nested; in use, first pass the terminal of the device to be connected through the first terminal interface 112 into and fix it inside the socket body 11, then fix the high-voltage socket 1 on the device, and then pass the cable terminal through the second terminal interface 212 into and fix it inside the plug body 21; nest and snap the high-voltage plug 2 onto the outer surface of the high-voltage socket 1, at which point the terminal of the device to be connected and the cable terminal are precisely connected, realizing the connection between the device to be connected and the cable; at this time, fix the high-voltage plug 2 on the device to be connected as well, completing the connection of the device to be connected.

[0047] It should be noted that the high-voltage socket 1 also includes a first connecting plate 12 and a locking block 13; wherein, the first connecting plate 12 is arranged around the socket body 11 at the end away from the socket opening 111, the first connecting plate 12 is fixedly connected to the socket body 11, and the first connecting plate 12 is provided with a plurality of first mounting holes 121; two locking blocks 13 are arranged on two opposite outer surfaces of the socket body 11, and the locking blocks 13 are fixedly connected to the socket body 11.

[0048] Furthermore, the first connecting plate 12 is used to connect with the device to be connected. The first connecting plate 12 is arranged around the end of the socket body 11 away from the socket opening 111. The first connecting plate 12 is fixedly connected to the socket body 11. The first connecting plate 12 is provided with a plurality of first mounting holes 121. The first connecting plate 12 can be fixed to the device to be connected by bolts through the plurality of mounting holes 121, thereby realizing the fixing of the high-voltage socket to the device to be connected. Two locking blocks 13 are arranged oppositely on two opposite outer surfaces of the socket body 11 for locking the high-voltage socket 1 and the high-voltage plug 2 together.

[0049] It should be noted that the high-voltage plug 2 also includes a second connecting plate 22, a bayonet 23, and a pressing block 24; wherein, the second connecting plate 22 is disposed on the side surface of the plug body 21 near the end of the plug opening 211, and the second connecting plate 22 is fixedly connected to the plug body 21, and the second connecting plate 22 is provided with a second mounting hole 221; two bayonet 23s are disposed on two opposite surfaces of the socket body 11, and the positions of the two bayonet 23s correspond one-to-one with the positions of the two locking blocks 13; one end of each of the two pressing blocks 24s is disposed on the end of each of the two bayonet 23s near the plug opening 211, and the other end of each of the two pressing blocks 24s passes through the top of each of the two bayonet 23s and is suspended at the end of each of the two bayonet 23s away from the plug opening 211; the ends of the two pressing blocks 24s disposed on the bayonet 23s near the plug opening 211 are both fixedly connected to the plug body 21; when the high-voltage socket 1 and the high-voltage plug 2 are nested, the two locking blocks 13s on both sides of the high-voltage socket 1 pass through the bayonet 23s on both sides of the high-voltage plug 2 and contact the two pressing blocks 24s on both sides of the high-voltage socket 1.

[0050] Furthermore, the second connecting plate 22 is used to connect with the device to be connected. The second connecting plate 22 has a second mounting hole 221. After the high-voltage socket 1 is fixed to the device to be connected by bolts, and the high-voltage plug 2 is nested in the high-voltage socket 1, and the terminals of the device to be connected contact with the cable terminals, the second connecting plate 22 can be fixed to the device to be connected by bolts through the second mounting hole 221, thus fixing the high-voltage plug 2 to the device to be connected. Two latches 23 are respectively provided on opposite surfaces of the plug body 21, corresponding one-to-one with two latches 13 on the high-voltage socket 1, used to latch the two latches 13 on the high-voltage socket 1, thereby achieving the latching connection between the high-voltage socket 1 and the high-voltage plug. One end of each of the two pressing blocks 24 is fixedly disposed at one end of each of the two latches 23 near the plug opening 211, and the other end of each pressing block 24 passes through the top of each of the two latches 23 and is suspended at the end of each latch 23 away from the plug opening 211. The ends of the latches 23 near the plug opening 211 are fixedly connected to the plug body 21. When the high-voltage socket 1 and the high-voltage plug 2 are nested, the two latches 13 on both sides of the high-voltage socket 1 pass through the latches 23 on both sides of the high-voltage plug 2 and contact the two pressing blocks 24 on both sides of the high-voltage socket 1. When it is necessary to separate the high-voltage plug 2 and the high-voltage socket 1 after they are latched, simply press the ends of the pressing blocks 24 on both sides that are suspended in the latches 23 and away from the plug opening 211, so that the pressing blocks 24 contact the latches 13. Using the point as the fulcrum, an outward pulling force is applied to the end of the pressing block 24 connected to the plug body 21, causing the pressing blocks 24 on both sides to pull outward simultaneously at the part where the plug body 21 is fixedly connected to the pressing block 24. This causes the plug opening 211 on both sides of the plug body 21 to be subjected to an outward pulling force, thereby expanding the socket opening 211. At this time, the locking blocks 13 on both sides of the high-voltage socket 1 separate from the locking slots 23 on both sides of the high-voltage plug 2, allowing the high-voltage plug 2 to be pulled off the high-voltage socket 1, thus completing the separation of the high-voltage socket 1 and the high-voltage plug 2.

[0051] It should be noted that the mating surface between the card block 13 and the card slot 23 is an inclined guide surface.

[0052] Furthermore, since the mating surface of the locking block 13 and the locking slot 23 is an inclined guide surface, it is easier for the locking block 13 to enter the locking slot 23 through the plug body 2, making the locking process of the high-voltage socket 1 and the high-voltage plug 2 more effortless.

[0053] It should be noted that the surface of the socket body 11 is provided with multiple guide blocks 113; the surface of the plug body 21 is provided with multiple raised guide grooves 213. When the high-voltage socket 1 and the high-voltage plug 2 are nested, the multiple guide blocks 113 slide into the multiple guide grooves 213 one by one. After the high-voltage socket 1 and the high-voltage plug 2 are nested, the multiple guide blocks 113 are set in the multiple guide grooves 213 one by one.

[0054] Furthermore, by having multiple guide blocks 113 on the surface of the socket body 11 correspond one-to-one with multiple guide grooves 213 on the surface of the plug body 21, a guiding function can be provided for the nesting process of the high-voltage plug 2 and the high-voltage socket 1, making the nesting process of the high-voltage plug 2 and the high-voltage socket 1 more convenient.

[0055] It should be noted that guide grooves 213 are provided on the surface of the plug body 21 away from the second connecting plate 22 and on the two sides where the bayonet 23 is provided; and multiple guide blocks 113 are provided on the surface of the socket body 11, which correspond one-to-one with the multiple guide grooves 213 on the plug body 21.

[0056] Furthermore, by setting guide grooves 213 and guide blocks 113 on the three corresponding surfaces of the plug body 21 and the socket body 11, an asymmetrical structure is achieved, which can prevent the high-voltage plug 2 and the high-voltage plug 1 from being reversed during the nesting process, thereby further improving the safety and reliability of the high-voltage connector.

[0057] It should be noted that the cross-sections of the guide groove 213 and the guide block 113 are either rectangular or trapezoidal.

[0058] Furthermore, the trapezoidal or rectangular guide block 113 and guide groove 2131 have simple structures and are easy to clean and maintain.

[0059] It should be noted that there are two of each of the first terminal interface 112 and the second terminal interface 212.

[0060] Furthermore, there are two of each of the first terminal interface 112 and the second terminal interface 212, so that both the first terminal interface 112 and the second terminal interface 212 can be connected to two terminals at the same time.

[0061] It should be noted that both the socket body 11 and the plug body 21 are made of elastic plastic.

[0062] Furthermore, due to its excellent elastic properties, the elastic plastic makes it easier to separate the high-voltage plug 2 and the high-voltage socket 1 by pressing the pressing block 24 to enlarge the plug opening 211 of the plug body 21, thereby making it easier to separate the high-voltage socket 1 and the high-voltage plug 2.

[0063] According to an embodiment of a high-voltage connector for new energy vehicles, during use, the terminals of the device to be connected pass through the first terminal interface 112 into the socket body 11 and are fixed inside the socket body 11 by the terminals of the device to be connected themselves. The cable terminals pass through the second terminal interface 212 into the plug body 21 and are fixed inside the plug body 21 by the cable terminals themselves. Multiple mounting holes 121 are provided on the first connecting plate 12, allowing the first connecting plate 12 to be fixed to the device to be connected by bolts. Multiple guide grooves 213 on the high-voltage plug 2 are aligned one-to-one with multiple guide blocks 113 on the high-voltage socket 1. The guide blocks 113 slide within the guide grooves 213, allowing the high-voltage plug 2 and the high-voltage socket 1 to be nested. After nesting, the terminals of the device to be connected and the cable terminals are in contact and connected. At this time, the second mounting holes 221 on the second connecting plate allow the second connecting plate 22 to be connected. The high-voltage plug 2 and high-voltage socket 1 are fixed to the device to be connected by bolts. When it is necessary to separate the high-voltage socket 1 and high-voltage plug 2 of the high-voltage connector, first unscrew the bolts connecting the high-voltage plug 2 to the device to be connected, and at the same time press the ends of the pressing blocks 24 on both sides that are suspended in the slots 23 away from the plug opening 211. The pressing blocks 24, with the point of contact between the pressing blocks 24 and the slots 13 as the fulcrum, apply an outward pulling force to the end of the pressing blocks 24 connected to the plug body 21. This causes the pressing blocks 24 on both sides to pull the part of the plug body 21 that is fixed to the pressing blocks 24 outward, so that the plug opening 211 on both sides of the plug body 21 is subjected to an outward pulling force, thereby expanding the socket opening 211. At this time, the slots 13 on both sides of the high-voltage socket 1 separate from the slots 23 on both sides of the high-voltage plug 2, and the high-voltage plug 2 can be pulled off the high-voltage socket 1, completing the separation of the high-voltage socket 1 and the high-voltage plug 2.
