Description

Technical Field

[0001] This utility model relates to the field of high-voltage connectors, specifically a high-voltage connector with high-voltage interlock. Background Technology

[0002] High-voltage interlock is a safety design method that uses low-voltage signals to monitor the integrity and continuity of high-voltage circuits. High-voltage connectors with high-voltage interlock can detect abnormal disconnection or damage to the high-voltage circuit through low-voltage signals before the high-voltage system is de-energized, and promptly send alarm signals to the battery management system (BMS) or vehicle control unit (VCU), enabling the system to take countermeasures, such as cutting off high-voltage power output or reducing power, thereby effectively preventing arcing and reducing safety risks.

[0003] However, the locking structure of most traditional high-voltage connectors is relatively complex, usually using two to three locking designs. Although this can improve the robustness, when the high-voltage connector is unexpectedly de-energized, it requires users to take more steps and have more skills, which increases the difficulty and time of disassembly and reduces the user experience. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most traditional high-voltage connectors have relatively complex locking structures, usually employing two to three locking designs. While this can improve robustness, it also increases the difficulty and time required for disassembly when the high-voltage connector is unexpectedly de-energized. This invention proposes a high-voltage connector with high-voltage interlock.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-voltage connector with high-voltage interlock, including a first connector and a second connector. A spacer sleeve is fixedly connected to one side of the first connector, and a spacer groove is opened on one side of the second connector. The surface of the spacer sleeve is movably inserted into the inner wall of the spacer groove. A locking structure is provided on one side of both the first connector and the second connector.

[0006] The locking structure includes a housing, one side of which is fixedly connected to one side of the first connector, a lock head is fixedly connected to one side of the housing, a lock groove is provided on one side of the housing, the inner cavity of the lock head is fixedly connected to an interlocking cavity, and a latch is movably connected to the inner wall of the interlocking cavity.

[0007] Preferably, the surface of the interlocking cavity is provided with a first clearance groove, and one side of the outer shell is provided with a second clearance groove.

[0008] Preferably, a lever is fixedly connected to the surface of the latch, and one side of the lever is slidably connected to the inner wall of the first clearance groove and the second clearance groove.

[0009] Preferably, the inner wall of the housing is movably connected to an elastic telescopic rod, one end of which is movably connected to one side of the lever.

[0010] Preferably, the inner wall of the spacer sleeve is fixedly connected to a mating post, one end of which is provided with an insertion hole, and the inner wall of the spacer groove is fixedly connected to a plug-in post, the surface of which is fixedly connected to the inner wall of the insertion hole.

[0011] Preferably, the inner wall of the spacer sleeve is fixedly connected to an interlocking connector, an interlocking slot is provided on one side of the interlocking connector, a high-voltage slot is provided on one side of the interlocking connector, an interlocking pin is fixedly connected to the inner wall of the spacer slot, the surface of the interlocking pin is fixedly inserted into the inner wall of the interlocking slot, and a high-voltage pin is fixedly connected to the inner wall of the spacer slot, the surface of the high-voltage pin is fixedly inserted into the inner wall of the high-voltage slot.

[0012] Preferably, one side of both the first connector and the second connector is fixedly connected to a suction pad, and one side of the suction pad is in contact with the other.

[0013] The advantages of this utility model are:

[0014] This utility model utilizes a first connector and a second connector, with the locking structure interconnected while the first and second connectors are connected. Lock heads on the outer shell are inserted into lock grooves on another set of outer shells. The latches are all semi-circular. As the lock head enters the lock groove, it pushes the latch in the interlocking cavity to rotate. When the first and second connectors abut, the two sets of latches engage to form a full-circular latch, which then resets and engages in the interlocking cavity. The rotation of the semi-circular latch simultaneously lifts the lever along the first and second clearance grooves. This allows for easy unlocking by simply moving the lever to release the interlock between the first and second connectors, improving the stability of the high-voltage connector installation and the ease of disassembly. It solves the problem that traditional high-voltage connectors often have complex locking structures, typically employing two to three locking designs. While these designs improve stability, they also require more steps and skills from the user when the high-voltage connector experiences an unexpected power outage, increasing the difficulty and time of disassembly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a high-voltage connector with high-voltage interlock. (Refer to...) Figures 1 to 4 A high-voltage connector with high-voltage interlock includes a first connector 1 and a second connector 2. A spacer sleeve 3 is fixedly connected to one side of the first connector 1, and a spacer groove 4 is opened on one side of the second connector 2. The surface of the spacer sleeve 3 is movably inserted into the inner wall of the spacer groove 4. A locking structure 5 is provided on one side of both the first connector 1 and the second connector 2.

[0024] The locking structure 5 includes a housing 501. One side of the housing 501 is fixedly connected to one side of the first connector 1. A lock head 502 is fixedly connected to one side of the housing 501. A lock groove 503 is formed on one side of the housing 501. An interlocking cavity 504 is fixedly connected to the inner cavity of the lock head 502. A latch 505 is movably connected to the inner wall of the interlocking cavity 504. A first clearance groove 6 is formed on the surface of the interlocking cavity 504. A second clearance groove 7 is formed on one side of the housing 501. A lever 8 is fixedly connected to the surface of the latch 505. One side of the lever 8 is slidably connected to the inner wall of the first clearance groove 6 and the second clearance groove 7. In this high-voltage connector with high-voltage interlock, the first connector 1 and the second connector 2 are connected by a spacer sleeve 3 and a spacer groove 4. The spacer sleeve 3 can improve the insulation effect of the connector. While connector 1 and connector 2 are connected, the locking structures 5 on connector 1 and connector 2 are connected to each other. The lock head 502 on the outer shell 501 is inserted into the lock groove 503 of another set of outer shell 501. The latches 505 are all set in a semi-circular shape. When the lock head 502 enters the lock groove 503, it pushes the latches 505 in the interlock cavity 504 to rotate. When connector 1 and connector 2 abut, the two sets of latches 505 bite together to form a full circular latch 505 and reset and lock into the interlock cavity 504. When the semi-circular latches 505 rotate, they drive the lever 8 to lift along the first relief groove 6 and the second relief groove 7. When unlocking, simply move the lever 8 to lift so that connector 1 and connector 2 can be released from interlock, which improves the firmness of the high voltage connector installation and the convenience of disassembly.

[0025] In addition, the outer shell 501 of the first connector 1, the second connector 2, the spacer sleeve 3, and the locking structure 5 are all made of insulating plastic material, which has good insulation and flame retardant effects.

[0026] Reference Figure 4 The inner wall of the outer shell 501 is movably connected to an elastic telescopic rod 9. One end of the elastic telescopic rod 9 is movably connected to one side of the lever 8. When the lock 505 is connected, the lever 8 is rotated and the elastic telescopic rod 9 is stretched. After the lock 505 is engaged, the lever 8 is pulled back to its original position by the rebound characteristic of the elastic telescopic rod 9, which improves the engagement stability of the lock 505.

[0027] Reference Figure 2 and Figure 3 The inner wall of the spacer sleeve 3 is fixedly connected to a docking post 10, and one end of the docking post 10 is provided with a socket 11. The inner wall of the spacer groove 4 is fixedly connected to a plug-in post 12, and the surface of the plug-in post 12 is fixedly connected to the inner wall of the socket 11. Through the docking post 10 and the plug-in post 12, the cable can be connected through one end of the first connector 1 and the second connector 2. The plug-in post 12 is inserted into the socket 11 of the docking post 10 to realize the connection between the cables.

[0028] Reference Figure 2and Figure 3 An interlocking connector 13 is fixedly connected to the inner wall of the spacer sleeve 3. An interlocking slot 14 is provided on one side of the interlocking connector 13, and a high-voltage slot 15 is provided on one side of the interlocking connector 13. An interlocking pin 16 is fixedly connected to the inner wall of the spacer slot 4. The surface of the interlocking pin 16 is fixedly inserted into the inner wall of the interlocking slot 14. A high-voltage pin 17 is fixedly connected to the inner wall of the spacer slot 4. The surface of the high-voltage pin 17 is fixedly inserted into the inner wall of the high-voltage slot 15. Through the interlocking pin 16 and the high-voltage pin 17, two sets of interlocking pin 16 and high-voltage pin 17 are respectively provided. The high-voltage pin 17 can be divided into high-voltage positive and high-voltage negative. The length of the interlocking pin 16 is shorter than the length of the high-voltage pin 17. When the first connector 1 and the second connector 2 are connected, the high-voltage pin 17 is first connected to the high-voltage slot 15, and the interlocking pin 16 is then connected to the interlocking slot 14 before being energized. When disassembling, because the interlocking pin 16 is shorter, it will first disconnect from the interlocking slot 14 and then de-energize, improving the safety of user operation.

[0029] Reference Figure 1 A suction pad 18 is fixedly connected to one side of both the first connector 1 and the second connector 2. The sides of the suction pads 18 are in contact with each other. The suction pads 18 are made of rubber. After the first connector 1 and the second connector 2 are connected, the rubber suction pads 18 fit together and seal the ports of the first connector 1 and the second connector 2, thereby improving the waterproof and dustproof effect.

[0030] Working principle: The cable can be connected through one end of the first connector 1 and the second connector 2. The first connector 1 and the second connector 2 are connected by a spacer sleeve 3 and a spacer slot 4. The connection between the cables is achieved by inserting the plug post 12 into the socket 11 of the mating post 10. The length of the interlocking pin 16 is shorter than the length of the high voltage pin 17. When the first connector 1 and the second connector 2 are mated, the high voltage pin 17 first connects to the high voltage slot 15, and the interlocking pin 16 then connects to the interlocking slot 14 before power is supplied. The locking structures 5 on the first connector 1 and the second connector 2 are interconnected, and the lock heads 502 on the outer casing 501 are respectively inserted into... In the locking groove 503 of another set of housings 501, the latches 505 are all set in a semi-circular shape. When the lock head 502 enters the locking groove 503, it pushes the latches 505 in the interlocking cavity 504 to rotate. When the first connector 1 and the second connector 2 abut, the two sets of latches 505 engage to form a full circular latch 505 and reset and lock into the interlocking cavity 504. When the semi-circular latches 505 rotate, they drive the lever 8 to lift along the first clearance groove 6 and the second clearance groove 7. When unlocking, simply move the lever 8 to lift so that the first connector 1 and the second connector 2 can be released from interlocking, which improves the firmness of the high-voltage connector installation and the convenience of disassembly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
