The plug terminals 6 and the socket terminals 37 are engaged. The first locking assembly can cooperate with the second locking assembly to lock the socket housing 35 onto the plug housing 1.

[0038] Specifically, when the plug housing 1 and the socket housing 35 are inserted, the first locking component and the second locking component cooperate to lock the socket housing 35 onto the plug housing 1, which improves the connection strength between the socket housing 35 and the plug housing 1 and prevents the socket housing 35 from separating from the plug housing 1. This ensures the stability of the insertion between the plug terminal 6 and the socket terminal 37, prevents the plug 46 from disconnecting from the socket 34, and improves the stability of the high-voltage connector.

[0039] In one embodiment, the first locking assembly includes a locking handle 5 and a locking buckle 3, the locking buckle 3 being connected to the plug housing 1, the locking handle 5 including a first mating part 12, a transition part 14 and a locking part 15, the transition part 14 being connected between the first mating part 12 and the locking part 15, and the first mating part 12 being rotatably mounted on the plug housing 1.

[0040] The first mating part 12 is rotatable between a locking angle and an unlocking angle. At the locking angle, the locking part 15 is locked to the latch 3, and at the unlocking angle, the locking part 15 is disengaged from the latch 3. The first mating part 12 is provided with a first mating structure.

[0041] The second locking component includes a second mating part 57 disposed on the socket housing 35. The second mating part 57 is provided with a second mating structure, which engages with the first mating structure.

[0042] Specifically, the latch 3 of the first locking component is connected to the plug housing 1. The locking handle 5 includes a connected first mating part 12, a transition part 14, and a locking part 15. The transition part 14 is located between the first mating part 12 and the locking part 15. A rotating shaft 11 is provided on the side of the plug housing 1. The first mating part 12 is rotatably mounted on the rotating shaft 11. The locking part 15 is a plate-shaped structure. The locking part 15 is located above the upper side of the plug housing 1 and is parallel to the upper side of the plug housing 1. The first mating structure is provided on the first mating part 12.

[0043] The second locking assembly includes a second mating part 57 disposed on the socket housing 35. A second mating structure is disposed on the second mating part 57. When the socket housing 35 is inserted into the first pair of socket holes 7 of the plug housing 1, the second mating structure engages with the first mating structure, driving the first mating part 12 to rotate to the locking angle. The structure is simple and easy to design.

[0044] In one embodiment, the first mating structure includes a gear 13 disposed on the first mating portion 12;

[0045] The second mating structure includes a rack 38 disposed on the second mating part 57. The rack 38 extends along the mating direction of the socket housing 35 and the plug housing 1. The rack 38 is used to mesh with the gear 13 and drive the gear 13 to rotate when the socket housing 35 is inserted into the first pair of socket holes 7.

[0046] Specifically, the first mating structure includes a gear 13 mounted on the first mating part 12, and the second mating structure includes a rack 38 mounted on the socket housing 35. The rack 38 extends along the insertion direction between the socket housing 35 and the plug housing 1. When the socket housing 35 is inserted into the first pair of socket holes 7, the rack 38 meshes with the gear 13. As the socket housing 35 is gradually inserted into the first pair of socket holes 7, the rack 38 drives the gear 13 to rotate, and the rotation of the gear 13 drives the first mating part 12 to rotate. When the socket housing 35 is fully inserted into the first pair of socket holes 7, the first mating part 12 rotates to the locking angle. By using the meshing transmission of the rack 38 and the gear 13, it is not necessary to design a separate power source to drive the first drive part to rotate, which can save production costs.

[0047] In one embodiment, the outer periphery of the plug housing 1 is provided with a guide groove 8, and the outer periphery of the socket housing 35 is provided with a guide block 36. The guide block 36 and the guide groove 8 extend along the insertion direction of the socket housing 35 and the plug housing 1, and the guide block 36 is slidably connected to the guide groove 8.

[0048] Specifically, the inner wall of the first pair of sockets 7 of the plug housing 1 is provided with a guide groove 8. The guide groove 8 extends along the insertion direction of the socket housing 35 and the plug housing 1. The outer peripheral surface of the socket housing 35 is provided with a guide block 36. The guide block 36 extends along the insertion direction of the socket housing 35 and the plug housing 1. When the socket housing 35 is inserted into the first pair of sockets 7, the guide block 36 slides into the guide groove 8, which can play a guiding role and prevent the socket housing 35 from tilting during the insertion process.

[0049] In one embodiment, the latch 3 is provided with a lock hole 9, and the lock handle 5 further includes a locking member 22. One end of the locking member 22 is slidably connected to the locking part 15, and the other end of the locking member 22 is inserted into the lock hole 9.

[0050] The locking part 15 is provided with a slot 16, the end of the slot 16 away from the latch 3 has an opening, and the slot wall of the end of the slot 16 near the latch 3 has a through hole 21.

[0051] The locking member 22 includes a plug plate 27, which is inserted into the slot 16 through the opening. The plug plate 27 has a plug-in part 28 at one end near the latch 3. The plug plate 27 has a plug-in position and a clearance position. In the plug-in position, the plug-in part 28 is plugged into the lock hole 9 through the through hole 21. In the clearance position, the plug-in part 28 is withdrawn from the lock hole 9.

[0052] Specifically, the locking part 15 is provided with a slot 16, and the locking member 22 includes an insert plate 27. The insert plate 27 is slidably inserted into the slot 16. The slot wall of the slot 16 is provided with a through hole 21. The end of the insert plate 27 near the latch 3 is a plug-in part 28. At the plug-in position, the insert plate 27 is inserted into the lock hole 9 of the latch 3 through the through hole 21, thereby limiting the locking part 15 in the thickness direction. At the clearance position, the insert plate 27 moves away from the latch 3, so that the plug-in part 28 exits from the lock hole 9, thereby unlocking the locking part 15.

[0053] In one embodiment, the locking member 22 further includes a driving structure for driving the insert plate 27 to move between the insertion position and the clearance position. The driving structure is connected to the insert plate 27 and is used to drive the insert plate 27 to move between the insertion position and the clearance position, so as to facilitate the operation of the insert plate 27.

[0054] In one embodiment, the driving structure includes a transition plate 23 and a driving plate 24. The transition plate 23 is connected to the end of the insert plate 27 away from the latch 3. The driving plate 24 is located above the insert plate 27. The transition plate 23 is connected between the insert plate 27 and the driving plate 24. The driving plate 24 is used to drive the insert plate 27 to move between the insertion position and the clearance position.

[0055] Specifically, the transition plate 23 is vertically arranged with the insertion plate 27, and the drive plate 24 is located above the insertion plate 27. The drive plate 24 is parallel to the insertion plate 27. By pushing the drive plate 24 to move, the drive plate 24 drives the insertion plate 27 to move between the insertion position and the avoidance position through the transition plate 23. The structure is simple and easy to design.

[0056] In one embodiment, the drive plate 24 has a booster stripe 25 on the side facing away from the insert plate 27, and the transition plate 23 has a booster step 26 at the position where it connects with the drive plate 24.

[0057] Specifically, the drive plate 24 has a push stripe 25 on the side facing away from the insert plate 27. The push stripe 25 can increase the friction of the drive plate 24, making it easier to push the drive plate 24 to move. The push step 26 is provided on the side of the drive plate 24 facing away from the insert plate 27. The push step 26 faces the latch 3 and can assist the operator in pushing the insert plate 27 away from the latch 3.

[0058] In one embodiment, the locking member 22 further includes a locking arm 29, which is connected to the transition plate 23. The locking arm 29 is arranged parallel to and spaced apart from the insert plate 27. The locking arm 29 is provided with a locking block 30, and the slot 16 is provided with a slot 20 on its groove wall. The locking block 30 engages with the slot 20.

[0059] Specifically, the slot 16 has a slot 20 on its side wall. The slot 20 is located at the junction of the side wall and the bottom wall of the slot 16. When the insert plate 27 moves close to the latch 3, the locking block 30 of the locking arm 29 will move into the slot 20 to lock the insert plate 27 and prevent it from coming out of the slot 16. In addition, the locking arm 29 is an elastic structure with an elongated hole 31, which allows the side of the locking arm 29 with the locking block 30 to float towards or away from the slot 20. When unlocking is required, the drive plate 24 is pushed outward, and the drive plate 24 drives the insert plate 27 to move away from the latch 3. When the locking hole contacts the slot wall of the slot 20, the slot wall of the slot 20 will force the side of the locking arm 29 with the locking block 30 to deform, so that the locking block 30 crosses the slot wall of the slot 20 and exits from the slot 20. At this time, the insert plate 27 of the insert plate 27 exits from the locking hole 9, thereby unlocking the locking part 15 and the latch 3.

[0060] In one embodiment, a spring arm 32 is provided between the insert plate 27 and the locking arm 29. The spring arm 32 is connected to the transition plate 23. A protrusion 33 is provided on the lower side of the spring arm 32. A guide groove 19 is provided on the bottom wall of the slot 16. The lower end of the protrusion 33 slides in the guide groove 19. A first through hole 17 is provided at the bottom of the slot 16. A second through hole 18 is provided near the first through hole 17. The second through hole 18 is located behind the first through hole 17. An upper top block 10 is provided on the upper side of the plug housing 1. When the lock handle 5 is in the locked position, the upper top block 10 is inserted into the second through hole 18 and pushes the protrusion 33 and the spring arm 32 upward. When the insert plate 27 moves to the insertion position, the protrusion 33 is inserted downward into the first through hole 17, thereby achieving further locking of the insert plate 27 and the slot 16.

[0061] In one embodiment, the plug 46 further includes a plug sealing ring 49, a plug shield 51, a plug core 52, a riveted outer ring 53, a riveted inner ring 54, a tail waterproof ring 55, a tail cap 56, a core baffle 50, a front baffle 48, and a signal spring 47. The plug sealing ring 49 is installed in the insertion groove 2 at the front end of the plug housing 1, the signal spring 47 is installed on the front baffle 48, and the front baffle 48 is installed at the front end of the plug housing 1. One end of the external cable 4 is welded and fixed to the plug terminal 6, and the other end of the external cable 4 is... The inner riveting ring 54 is fitted onto the external cable 4, and the outer riveting ring 53 is fitted onto the inner riveting ring 54. The inner riveting ring 54 and the outer riveting ring 53 are pressed tightly onto the external cable 4 by riveting. The plug core 52 is inserted into the plug shield 51. The core baffle 50 is installed at the front end of the plug core 52. The plug terminal 6 is inserted into the plug core 52 from back to front. The plug core 52 and the plug shield 46 are inserted into the plug housing 1. Finally, the tail waterproof ring 55 and the tail cap 56 are installed at the rear end of the plug housing 1.

[0062] In one embodiment, the socket 34 further includes a terminal spring clip 40, a socket shield 39, a socket signal pin 41, a terminal sealing ring 44, a signal core 42, a signal jack 43, and a socket sealing ring 45.

[0063] The working principle of the high-voltage connector of this utility model embodiment is as follows:

[0064] The socket housing 35 is inserted into the first pair of socket holes 7 of the plug 46. During the insertion process, the rack 38 on the socket housing 35 is inserted into the insertion groove 2 of the socket housing 35 and passes through the clearance hole at the bottom of the insertion groove 2 to mesh with the gear 13 on the lock handle 5. When the socket housing 35 is pushed toward the plug housing 1, the rack 38 drives the gear 13 to rotate. The gear 13 drives the lock handle 5 to rotate from the unlocked position to the locked position. After the insertion is completed, the locking part 15 is attached to the upper side of the plug housing 1. Then, the drive plate 24 is pushed toward the latch 3 so that the insertion plate of the insertion plate 27 is inserted into the lock hole 9 of the latch 3. At the same time, the protrusion 33 of the spring arm 32 is inserted downward into the first through hole 17, and the locking block 30 on the locking arm 29 is engaged in the slot 20 on the side wall of the slot 16, so as to realize the locking between the locking member 22, the locking part 15 and the latch 3.

[0065] According to the present invention, when the plug housing 1 and the socket housing 35 are inserted, the first locking component and the second locking component cooperate to lock the socket housing 35 onto the plug housing 1, thereby improving the connection strength between the socket housing 35 and the plug housing 1 and preventing the socket housing 35 from separating from the plug housing 1. This ensures the insertion stability between the plug terminal 6 and the socket terminal 37, prevents the plug 46 from disconnecting from the socket 34, and improves the stability of the high-voltage connector.
