[0035] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] like Figures 1 to 12As shown, an embodiment of this utility model provides a high-voltage connector, including a plug 1 and a socket 38. The plug 1 includes a plug housing 2, a locking handle 6, a first stop structure, and a second stop structure. The plug housing 2 is provided with a latch 3. The latch 3 includes a rotating part 14, a middle part 18, and a locking part 19. The middle part 18 is connected between the rotating part 14 and the locking part 19. The rotating part 14 is rotatably assembled with the plug housing 2. The locking handle 6 can swing between a locked position and a starting position. In the locked position, the locking part 19 is locked with the latch 3. In the starting position, the locking part 19 is disengaged from the latch 3.

[0037] The socket 38 includes a socket housing 39, on which a rack 41 is provided. The rotating part 14 is provided with a gear 15. The rack 41 engages with the gear 15 and drives the gear 15 to rotate when the socket housing 39 is inserted into the plug housing 2, causing the locking handle 6 to swing between the starting position and the locked position. A first stop structure is connected to the plug housing 2, and a second stop structure is connected to the locking handle 6. The first stop structure and the second stop structure engage to hold the locking handle 6 in the starting position.

[0038] Specifically, the rotating part 14 is rotatably mounted on the rotating shaft 10 of the plug housing 2. The gear 15 is mounted on the rotating part 14. The plug housing 2 has a insertion groove 11 for the rack 41 to be inserted. The rack 41 passes through the clearance hole 12 at the bottom of the insertion groove 11 and meshes with the gear 15. The rack 41 extends along the insertion direction of the socket housing 39 and the plug housing 2. When the socket housing 39 is inserted into the plug housing 2, the rack 41 meshes with the gear 15. As the socket housing 39 gradually goes deeper, the rack 41 drives the gear 15 to rotate. The rotation of the gear 15 drives the rotating part 14 to rotate. When the socket housing 39 is fully inserted into the plug housing 2, the locking handle 6 swings to the locked position. By using the meshing transmission of the rack 41 and the gear 15, it is not necessary to design a separate power source to drive the first drive part to rotate, which can save production costs.

[0039] The first stop structure is connected to the plug housing 2, and the second stop structure is connected to the middle part 18 of the lock handle 6. In the starting position of the lock handle 6, the first stop structure and the second stop structure cooperate to keep the lock handle 6 in the starting position when the socket housing 39 and the plug housing 2 are not plugged in, so as to prevent the swing angle of the lock handle 6 from being too large. Thus, when the socket housing 39 and the plug housing 2 are plugged in, the rack 41 on the socket housing 39 meshes with the gear 15 on the plug housing 2, driving the rotating part 14 to rotate, so that the lock handle 6 swings to the locked position.

[0040] In one embodiment, the inner wall of the plug housing 2 is provided with a guide groove 13, and the outer periphery of the socket housing 39 is provided with a guide block 40. The guide block 40 and the guide groove 13 extend along the insertion direction of the socket housing 39 and the plug housing 2, and the guide block 40 is slidably connected to the guide groove 13.

[0041] Specifically, the inner wall of the plug housing 2 is provided with a guide groove 13, which extends along the insertion direction of the socket housing 39 and the plug housing 2. The outer peripheral surface of the socket housing 39 is provided with a guide block 40, which extends along the insertion direction of the socket housing 39 and the plug housing 2. The guide block 40 is slidably inserted into the guide groove 13, which can play a guiding role and prevent the socket housing 39 from tilting during the insertion process.

[0042] In one embodiment, the first stop structure includes a first stop 4, which protrudes from the plug housing 2 on the side facing the lock handle 6. The second stop structure includes a second stop 5, which protrudes from the middle portion 18 of the lock handle 6 on the side facing the plug housing 2. The second stop 5 is used to engage with the first stop 4 at the starting position of the lock handle 6.

[0043] Specifically, the socket housing 39 is inserted into the plug 1 from the front end of the plug housing 2. The first stop 4 protrudes from the side of the plug housing 2 facing the locking handle 6. The first stop 4 is located at the front end of the plug housing 2. The second stop 5 protrudes from the middle part 18 of the locking handle 6, located on the side of the locking handle 6 facing the plug housing 2. When the socket housing 39 and the plug housing 2 are not plugged in, the first stop 4 can cooperate with the second stop 5 to prevent the locking handle 6 from passing the first stop 4, thereby preventing the swing angle of the locking handle 6 from being too large. Before the socket housing 39 is inserted into the plug housing 2, the locking handle 6 is first swung to the position of the first stop 4 so that the locking handle 6 is in the starting position. Then, when the socket housing 39 is fully plugged into the plug housing 2, the locking part 19 of the locking handle 6 can cooperate with the latch 3 to lock.

[0044] In one embodiment, the plug housing 2 has a support step at the end away from the latch 3, the support step being used to support the locking part 19 at the starting position.

[0045] Specifically, the support step is set at the front end of the plug housing 2, and the locking part 19 is a plate structure. When the locking handle 6 is not in the starting position, the locking part 19 is perpendicular to the upper side of the plug housing 2. The support step supports the locking part 19 and further supports the locking part 19.

[0046] In one embodiment, the rack 41 is provided with at least two teeth, including a first tooth 42 and a second tooth 43. The side of the first tooth 42 facing away from the lock handle 6 is flush with the side of the second tooth 43 facing away from the lock handle 6. The thickness of the first tooth 42 is greater than the thickness of the second tooth 43. The first tooth 42 and the second tooth 43 are arranged alternately.

[0047] The gear 15 is provided with at least two tooth grooves, including a first tooth groove 16 and a second tooth groove 17. The depth of the first tooth groove 16 in the thickness direction of the rotating part 14 is greater than the depth of the second tooth 43 in the thickness direction of the rotating part 14. The first tooth groove 16 and the second tooth groove 17 are arranged alternately.

[0048] The first tooth 42 corresponds one-to-one with the first tooth groove 16, and the first tooth 42 is used to mesh with the first tooth groove 16. The second tooth 43 corresponds one-to-one with the second tooth groove 17, and the second tooth 43 is used to mesh with the second tooth groove 17.

[0049] Specifically, in this embodiment, the rack 41 is provided with two teeth, including a first tooth 42 and a second tooth 43. The second tooth 43 is located at the front end of the first tooth 42. The side of the first tooth 42 facing away from the lock handle 6 is flush with the side of the second tooth 43 facing away from the lock handle 6. The thickness of the first tooth 42 is greater than the thickness of the second tooth 43.

[0050] The gear 15 has two tooth grooves, including a first tooth groove 16 and a second tooth groove 17. The first tooth groove 16 is located at the rear end of the second tooth groove 17. The depth of the first tooth groove 16 in the thickness direction of the rotating part 14 is greater than the depth of the second tooth 43 in the thickness direction of the rotating part 14.

[0051] The first tooth 42 corresponds to the first tooth groove 16, and the second tooth 43 corresponds to the second tooth groove 17. When the socket housing 39 is inserted into the plug housing 2, the second tooth 43 first engages with the second tooth groove 17, and the first tooth 42 then engages with the first tooth groove 16. If the locking handle 6 is not in the starting position when the socket housing 39 is inserted into the plug housing 2, then the second tooth 43 cannot be inserted into the second tooth groove 17, and thus cannot drive the gear 15 to rotate, thereby preventing the locking handle 6 from being fooled. Only when the locking handle 6 is in the starting position can the second tooth 43 engage with the second tooth groove 17.

[0052] In one embodiment, the latch 3 is provided with a lock hole 8, and the lock handle 6 further includes a locking member 7. One end of the locking member 7 is slidably connected to the locking part 19, and the other end of the locking member 7 is inserted into the lock hole 8.

[0053] The locking part 19 is provided with a slot 20, the end of the locking groove away from the latch 3 has an opening, and the groove wall of the end of the locking groove near the latch 3 is provided with a through hole 25.

[0054] The locking member 7 includes a insert plate 30, which is inserted into the slot 20 through the opening. The insert plate 30 has a plug-in part 31 at one end near the latch 3. The insert plate 30 has a plug-in position and a clearance position. In the plug-in position, the plug-in part 31 is plugged into the lock hole 8 through the through hole 25. In the clearance position, the plug-in part 31 is withdrawn from the lock hole 8.

[0055] Specifically, the locking part 19 is provided with a slot 20, and the locking member 7 includes an insert plate 30. The insert plate 30 is slidably inserted into the slot 20. The slot wall of the slot 20 is provided with a through hole 25. The end of the insert plate 30 near the latch 3 is the insertion part 31. At the insertion position of the insert plate 30, the insert plate 30 is inserted into the lock hole 8 of the latch 3 through the through hole 25, thereby limiting the locking part 19 in the thickness direction. At the clearance position of the insert plate 30, the insert plate 30 is moved away from the latch 3, so that the insertion part 31 is withdrawn from the lock hole 8, thereby unlocking the locking part 19.

[0056] In one embodiment, the locking member 7 further includes a driving structure for driving the insert plate 30 to move between the insertion position and the clearance position. The driving structure is connected to the insert plate 30 and is used to drive the insert plate 30 to move between the insertion position and the clearance position, so as to facilitate the operation of the insert plate 30.

[0057] In one embodiment, the driving structure includes a transition plate 27 and a driving plate 28. The transition plate 27 is connected to the end of the insert plate 30 away from the latch 3. The driving plate 28 is located above the insert plate 30. The transition plate 27 is connected between the insert plate 30 and the driving plate 28. The driving plate 28 is used to drive the insert plate 30 to move between the insertion position and the clearance position.

[0058] Specifically, the transition plate 27 is set perpendicular to the insertion plate 30, and the drive plate 28 is located above the insertion plate 30. The drive plate 28 is set parallel to the insertion plate 30. By pushing the drive plate 28, the drive plate 28 drives the insertion plate 30 to move between the insertion position and the clearance position through the transition plate 27. The structure is simple and easy to design.

[0059] In one embodiment, the drive plate 28 has a booster stripe 29 on the side facing away from the insert plate 30, and a booster step 26 on the side facing away from the insert plate 30.

[0060] Specifically, the drive plate 28 has a push stripe 29 on the side facing away from the insert plate 30. The push stripe 29 can increase the friction of the drive plate 28, making it easier to push the drive plate 28 to move. The push step 26 is provided on the side of the drive plate 28 facing away from the insert plate 30, and the push step 26 faces the latch 3. It can assist the operator in pushing the insert plate 30 away from the latch 3.

[0061] In one embodiment, the locking member 7 further includes a locking arm 33, which is connected to the transition plate 27. The locking arm 33 is arranged parallel to and spaced apart from the insert plate 30. The locking arm 33 is provided with a locking block 34, and the slot 20 is provided with a slot 24 on its groove wall. The locking block 34 engages with the slot 24.

[0062] Specifically, the side wall of the lock groove is provided with a slot 24. The slot 24 is provided at the position where the side wall of the lock groove meets the bottom wall of the groove. When the insert plate 30 moves close to the latch 3, the locking block 34 of the lock arm 33 will move into the slot 24 to achieve the locking of the locking block 34 and the slot 24, thus preventing the insert plate 30 from coming out of the slot 20. In addition, the locking arm 33 is an elastic structure with an elongated hole 35, which allows the side of the locking arm 33 with the locking block 34 to float towards or away from the slot 24. When unlocking is required, the drive plate 28 is pushed outward, and the drive plate 28 drives the insert plate 30 to move away from the latch 3. When the locking hole contacts the slot wall of the slot 24, the slot wall of the slot 24 will force the side of the locking arm 33 with the locking block 34 to deform, so that the locking block 34 crosses the slot wall of the slot 24 and exits from the slot 24. At this time, the insert plate 30 of the insert plate 30 exits from the lock hole 8, thereby unlocking the locking part 19 and the latch 3.

[0063] In one embodiment, a spring arm 36 is provided between the insert plate 30 and the locking arm 33. The spring arm 36 is connected to the transition plate 27. A protrusion 37 is provided on the lower side of the spring arm 36. A guide groove 23 is provided on the bottom wall of the lock groove. The lower end of the protrusion 37 slides in the guide groove 23. A first through hole 21 is provided at the bottom of the slot 20. A second through hole 22 is provided near the first through hole 21. The second through hole 22 is located behind the first through hole 21. An upper top block 9 is provided on the upper side of the plug housing 2. When the lock handle 6 is in the locked position, the upper top block 9 is inserted into the second through hole 22 and pushes the protrusion 37 and the spring arm 36 upward. When the insert plate 30 moves to the insertion position, the protrusion 37 is inserted downward into the first through hole 21 to achieve further locking of the insert plate 30 and the lock groove.

[0064] In one embodiment, the plug 1 further includes a plug sealing ring 53, a plug shield 55, a plug core 54, a riveted outer ring 58, a riveted inner ring 59, a tail waterproof ring 60, a plug tail clip 61, a tail cap 62, a core baffle 56, a front baffle 52, and a signal spring 51. The plug sealing ring 53 is installed in the insertion groove 11 at the front end of the plug housing 2, the signal spring 51 is installed on the front baffle 52, the front baffle 52 is installed at the front end of the plug housing 2, one end of the external cable is welded and fixed to the plug terminal 57, and the other end of the external cable is... The inner riveting ring 59 is fitted onto the external cable, and the outer riveting ring 58 is fitted onto the inner riveting ring 59. The inner riveting ring 59 and the outer riveting ring 58 are pressed tightly onto the external cable by riveting. The plug core 54 is inserted into the plug shield 55. The core baffle 56 is installed at the front end of the plug core 54. The plug terminal 57 is inserted into the plug core 54 from back to front. The plug core 54 and the plug shield 1 are then inserted into the plug housing 2. Finally, the plug tail clip 61, the tail waterproof ring 60, and the tail cover 62 are installed at the rear end of the plug housing 2.

[0065] In one embodiment, the socket 38 further includes a terminal spring clip 44, a socket shield 45, a socket signal pin 46, a terminal sealing ring 48, a signal core 47, a signal jack, a socket sealing ring 50, and a copper sleeve 32.

The socket shield 45 is installed on the front side of the socket housing 39, the terminal sealing ring 48 is fitted over the middle of the socket terminal 49, the socket terminal 49 is inserted into the socket housing 39, the terminal spring clip 44 is installed on the front end of the socket housing 39, the socket sealing ring 50 is installed on the front side of the socket housing 39, and finally the socket signal pin 46 is inserted into the signal jack of the signal core 47.

[0066] The working principle of the high-voltage connector of this utility model embodiment is as follows:

[0067] Before insertion, swing the lock handle 6 to the starting position so that the first stop 4 and the second stop 5 are stopped. Then, insert the socket housing 39 into the socket housing 39. During insertion, the rack 41 on the socket housing 39 will insert into the insertion slot 11 of the socket housing 39 and pass through the clearance hole 12 at the bottom of the insertion slot 11 to mesh with the gear 15 on the lock handle 6. When the socket housing 39 is pushed toward the plug housing 2, the rack 41 will drive the gear 15 to rotate, and the gear 15 will... When the moving lock handle 6 is rotated from the starting position to the locked position, after the insertion is completed, the locking part 19 is attached to the upper side of the plug housing 2. Then, the drive plate 28 is pushed towards the latch 3, so that the plug plate of the plug plate 30 is inserted into the lock hole 8 of the latch 3. At the same time, the protrusion 37 of the spring arm 36 is inserted downward into the first through hole 21, and the locking block 34 on the locking arm 33 is engaged in the slot 24 on the side wall of the lock groove, thereby realizing the locking between the locking member 7, the locking part 19 and the latch 3.

[0068] According to the high-voltage connector of this utility model embodiment, compared with the prior art, the first stop structure and the second stop structure cooperate to keep the locking handle 6 in the starting position when the socket housing 39 and the plug housing 2 are not plugged in, so as to avoid the swing angle of the locking handle 6 being too large. When the socket housing 39 and the plug housing 2 are plugged in, the rack 41 on the socket housing 39 meshes with the gear 15 on the plug housing 2, thereby driving the rotation to make the locking handle 6 swing to the locked position.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
