[0023] In one embodiment, see Figure 1 , Figure 2 and Figure 3 A new energy vehicle high-voltage line electrical connector comprises an access end 2 and an insertion end 1, wherein the end of the access end 2 is integrally formed with a plurality of guide rods 6 distributed in a circumference, and the end of the insertion end 1 is provided with a plurality of guide grooves 7 distributed in a circumference and adapted to the guide rods 6, wherein the guide rods 6 are rotatably connected with a rotating rod 8 inside, wherein one end of the rotating rod 8 is located inside the access end 2 and is connected with a rotating mechanism 3, wherein the rotating mechanism 3 is used to drive the rotating rod 8 to rotate, wherein a self-locking mechanism 4 is provided between the guide rod 6 and the guide groove 7, and a sealing mechanism 5 is provided between the access end 2 and the insertion end 1, wherein when the rotating mechanism 3 drives the rotating rod 8 to rotate, the self-locking mechanism 4 is used to fix the guide rod 6 inside the guide groove 7, and the sealing mechanism 5 is used to seal the access end 2 and the insertion end 1.

[0024] In this embodiment, when the electrical connector is in use, the insertion end 1 is inserted into the access end 2 until the conductive terminal at the end of the insertion end 1 completely enters the terminal groove inside the access end 2. During the insertion of the insertion end 1 into the access end 2, the guide rod 6 at the end of the access end 2 enters the guide groove 7 inside the insertion end 1.

When the gear ring 32 rotates, the rotating rod 8 is driven to rotate by meshing with the gear 31, so that the self-locking mechanism 4 can fix the guide rod 6 in the guide groove 7, and the sealing mechanism 5 can complete the sealing of the access end 2 and the insertion end 1. When the lever 34 moves, it will also squeeze the first elastic member 35, so that the first elastic member 35 is in a compressed state. The first elastic member 35 can be a spring. When the self-locking mechanism 4 fixes the guide rod 6 in the guide groove 7 When the access end 2 and the insertion end 1 need to be separated, the positioning of the toothed ring 32 by the positioning assembly is released. At this time, the first elastic member 35 releases its elastic potential energy, thereby driving the toothed ring 32 to reset through the lever 34, thereby releasing the fixation of the guide rod 6 by the self-locking mechanism 4 and the sealing mechanism 5 on the access end 2 and the insertion end 1, so as to facilitate the staff to separate the access end 2 from the insertion end 1.

[0026] See also Figure 3 The positioning assembly includes a pin rod 37 penetrating the side wall of the insertion end 1, one end of the pin rod 37 is in contact with the side wall of the gear ring 32, and a stopper 36 is fixed to the other end of the pin rod 37. The stopper 36 is connected to the outer wall of the access end 2 through a second elastic member 38, wherein a pin groove 39 adapted to the pin rod 37 is provided on the side wall of the gear ring 32; When the self-locking mechanism 4 fixes the guide rod 6 in the guide groove 7, and the sealing mechanism 5 completes the sealing of the access end 2 and the insertion end 1, the pin rod 37 is aligned with the pin groove 39 on the side wall of the toothed ring 32. At this time, under the action of the stop block 36 and the second elastic member 38, the end of the pin rod 37 automatically enters the pin groove 39, thereby fixing the toothed ring 32. The second elastic member 38 can be a spring. When it is necessary to separate the insertion end 1 and the access end 2, the pin rod 37 can be moved to the outside of the pin groove 39 through the stop block 36.

[0027] See also Figure 3A plurality of limiting blocks 310 for limiting the gear ring 32 are fixed on the inner wall of the access end 2 and are distributed in a circumference. A limiting groove is provided inside the limiting block 310. The gear ring 32 passes through the limiting groove and is slidably connected to the limiting groove. The gear ring 32 slides inside the limiting groove while moving, and the limiting groove can limit the gear ring 32, thereby effectively improving the stability of the gear ring 32 when moving.

[0028] See also Figure 4 The self-locking mechanism 4 is arranged in a groove body inside the guide rod 6, and a block 44 is penetrated on the side wall of the groove body, wherein a groove 45 adapted to the block 44 is arranged on the inner wall of the guide groove 7, and the block 44 is connected with a pushing component, and when the rotating rod 8 rotates, the pushing component is used to push the block 44 into the groove 45; When the insertion end 1 is connected to the access end 2, the block 44 inside the guide rod 6 is aligned with the slot 45 on the inner wall of the guide groove 7. At this time, the rotating rod 8 can be rotated while the end of the block 44 can be pushed into the slot 45 through the pushing component. The slot 45 fixes the guide rod 6 through the block 44, and then connects the access end 2 and the insertion end 1, effectively improving the stability between the two.

[0029] See also Figure 4 The pushing assembly includes a pressing plate 42 fixedly connected to the end of the clamping block 44, the pressing plate 42 is connected to the inner wall of the tank body through a third elastic member 43, and a convex block 41 for pressing the pressing plate 42 is fixed to the end of the rotating rod 8; When the insertion end 1 is connected with the access end 2, the rotating rod 8 is driven to rotate by the rotating mechanism 3, and the rotating rod 8 drives the protrusion 41 at its end to rotate inside the groove body. When the protrusion 41 rotates to a certain extent, the protrusion 41 contacts and squeezes the pressure plate 42. At this time, the pressure plate 42 drives the card block 44 to move, so that the end of the card block 44 enters the card slot 45, thereby connecting the access end 2 and the insertion end 1. When the access end 2 and the insertion end 1 need to be disassembled, the rotating mechanism 3 drives the rotating rod 8 to rotate in the opposite direction, and the degree of squeezing of the pressure plate 42 by the protrusion 41 is reduced. The pressure plate 42 drives the card block 44 to move to the inside of the positioning rod under the action of the third elastic member 43. At this time, the card slot 45 does not fix the positioning rod through the card block 44, which facilitates the separation of the access end 2 and the insertion end 1. The third elastic member 43 can be a spring.

[0030] See also Figure 2 , Figure 3 and Figure 5The sealing mechanism 5 comprises a circular groove arranged on the inner wall of the access end 2, a circular airbag 51 is installed inside the circular groove, wherein the circular airbag 51 is connected to an inflatable component, and when the rotating rod 8 rotates, the inflatable component is used to inflate the circular airbag 51; When the insertion end 1 is connected to the access end 2, the rotating rod 8 is driven to rotate by the rotating mechanism 3. While the rotating rod 8 rotates, air is inflated into the circular airbag 51 through the inflation component, so that the circular airbag 51 expands and fits tightly with the outer wall of the insertion end 1. At this time, the circular airbag 51 can seal the gap between the access end 2 and the insertion end 1, thereby preventing moisture in the air from entering the terminal slot inside the access end 2.

[0031] See also Figure 5 The inflatable component includes an air cavity 57 arranged inside the access end 2, the air cavity 57 is connected with an air pipe 58, the other end of the air pipe 58 is connected with the circular air bag 51, the air cavity 57 is slidably connected with a piston 56, the piston 56 is connected to the inner wall of the air cavity 57 through a fourth elastic member 55, wherein the piston 56 is fixedly connected with a slide rod 54, the end of the slide rod 54 away from the piston 56 passes through the inner wall of the access end 2 and is fixedly connected with a trapezoidal block 53, wherein the outside of the rotating rod 8 is fixed with an extrusion block 52 for extruding the trapezoidal block 53; When the rotating rod 8 rotates, it also drives the extrusion block 52 outside it to rotate. When the extrusion block 52 rotates to a certain extent, the extrusion block 52 squeezes the inclined surface of the trapezoidal block 53, so that the trapezoidal block 53 drives the piston 56 to slide inside the air cavity 57 through the sliding rod 54. The piston 56 squeezes the gas inside the air cavity 57, so that the gas inside the air cavity 57 enters the circular air bag 51 through the air pipe 58, thereby making the circular air bag 51 expand and fit tightly with the outer wall of the insertion end 1. The fourth elastic member 55 can be a spring. When the extrusion block 52 no longer squeezes the trapezoidal block 53, it can play a resetting role on the piston 56, and a negative pressure is formed inside the air cavity 57, so that the gas inside the circular air bag 51 flows back to the air cavity 57.

[0032] Working principle: When the electrical connector is in use, the insertion end 1 is inserted into the access end 2 until the conductive terminal at the end of the insertion end 1 completely enters the terminal slot inside the access end 2, and during the insertion of the insertion end 1 into the access end 2, the guide rod 6 at the end of the access end 2 will enter the guide slot 7 inside the insertion end 1. When the access end 2 and the insertion end 1 are connected, the lever 34 is toggled to drive the gear ring 32 to rotate. While the gear ring 32 rotates, it drives the rotating rod 8 to rotate through the engagement with the gear 31. The rotating rod 8 drives the protrusion 41 at its end to rotate inside the groove body. When the protrusion 41 rotates to a certain extent, the protrusion 41 contacts and squeezes the pressure plate 42. At this time, the pressure plate 42 drives the block 44 to move, so that the end of the block 44 enters the card slot 45. The card slot 45 fixes the guide rod 6 through the block 44, thereby connecting the access end 2 and the insertion end 1. It effectively ensures the stability between the access end 2 and the insertion end 1, and when connecting the line, the staff does not need to fix the access end 2 and the insertion end 1 by tightening the screws, which saves time and improves the connection efficiency of the high-voltage line of new energy vehicles. In addition, the rotation of the rotating rod 8 also drives the extrusion block 52 outside it to rotate. When the extrusion block 52 rotates to a certain extent, the extrusion block 52 squeezes the inclined surface of the trapezoidal block 53, so that the trapezoidal block 53 drives the piston 56 to slide inside the air cavity 57 through the sliding rod 54. The piston 56 squeezes the gas inside the air cavity 57, so that the gas inside the air cavity 57 enters the circular airbag 51 through the air pipe 58, and then the circular airbag 51 expands and fits tightly with the outer wall of the insertion end 1, which plays a sealing role in the gap between the access end 2 and the insertion end 1, thereby preventing moisture in the air from entering the terminal slot inside the access end 2, and improving the service life of the high-voltage line.
