Description

Technical Field

[0001] This invention belongs to the field of connector technology, specifically a high-voltage, high-current connector. Background Technology

[0002] High-voltage, high-current connectors are used in power systems and equipment. They are electronic components that connect two active devices. Connectors are primarily used to transmit current and optical signals, preventing signal distortion and energy loss between systems. Their function is to ensure stable and safe electrical connections between power equipment, and to withstand high voltage and high current, preventing equipment damage or accidents caused by overload, overheating, or arcing. They are commonly installed in automobiles as important interfaces for signal or current transmission.

[0003] In the prior art, during the insertion and removal process of high-voltage current connectors, arcing may occur at the high-voltage contact surface. When the connector terminals come into contact, arcing may occur due to large instantaneous changes in current and voltage, which may lead to damage or fire. Summary of the Invention

[0004] To address the problem of arcing at the contact surface mentioned in the background art, where the current is not interrupted in time, causing the current to continue flowing at the moment of contact separation, generating an arc and damaging the device, this invention provides a high-voltage, high-current connector.

The outer wall of the fixed housing is fixedly connected to the inner wall of the plug housing. A movable plate is slidably connected to the bottom of the inner wall of the fixed housing.

[0007] Preferably, a curved plate is fixedly connected to one side of the movable plate, one end of the curved plate penetrates through the fixed shell and extends to the outside of the plug shell, a horizontal plate is fixedly connected to the end of the curved plate away from the movable plate, a connecting block is fixedly connected to the top of one end of the horizontal plate, and a conical air tube is connected to both ends of one side of the fixed shell.

[0008] Preferably, a protective component is provided at one end of the high-voltage terminal line. The protective component includes a rubber sleeve that is slidably connected to the outer wall of one end of the high-voltage terminal line. Two rubber sleeves are provided, and a fixing plate is fixedly connected between the two rubber sleeves. A crossbar is fixedly connected to one side of the fixing plate.

[0009] Preferably, the end of the crossbar away from the fixed plate is fixedly connected to the side wall of the sliding plate, and a compression spring is fixedly connected to the side of the crossbar near the fixed plate. One end of the compression spring is fixedly connected to one side of the outer wall of the fixed shell, and four first elastic elements are respectively slidably connected through one side of the sliding plate.

[0010] Preferably, two of the first elastic elements are arranged in a group, and a circular plate is fixedly connected to one end of the group of first elastic elements. A sealing ring is fixedly connected to the side of the circular plate near the first elastic element, and two circular holes are respectively opened on the side of the sliding plate near the first elastic element.

[0011] Preferably, the sidewall of the sliding plate is provided with a stabilizing component, the stabilizing component including connecting plates fixedly connected to both ends of one side of the sliding plate, and an elastic telescopic rod fixedly connected to the side of the connecting plate away from the sliding plate, the elastic telescopic rod being disposed inside the conical trachea.

[0012] Preferably, a sealing ball is fixedly connected to the end of the elastic telescopic rod away from the connecting plate, the outer wall of the sealing ball is in contact with the inner wall of one end of the conical trachea, and a second elastic element passes through one side of the connecting block.

[0013] Preferably, one end of the second elastic element is fixedly connected to a locking block, the locking plate has a strip groove on the side near the rotating shell, and the outer wall of the rotating shell has a square hole.

[0014] Preferably, one end of the square hole is connected to an arc-shaped hole, one side of the arc-shaped hole is opened on one side of the rotating shell, and one end of the plug shell near the high-voltage terminal line is connected to a one-way air inlet pipe, one end of the one-way air inlet pipe is connected to the inner wall of the fixed shell.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention, through the coordination of anti-electric shock components, first pushes the connecting block towards the working box when the plug housing is pulled out. During this movement, the connecting block pushes the sliding plate, causing it to push nitrogen gas from inside the fixed housing into the conical gas inlet tube. The nitrogen gas then enters the socket and plug housings through the conical gas inlet tube, effectively suppressing arc generation due to the chemical stability of nitrogen. When the high-voltage terminal is separated from the high-voltage terminal line, the injection of nitrogen gas quickly dissipates the arc energy, preventing damage to the equipment. Furthermore, the gas injection inflates the internal areas of the socket and plug housings, reducing mechanical stress during pull-out and contributing to improved equipment durability and reliability.

[0017] This invention, through the coordinated arrangement of anti-electric shock components, protective components, and stabilizing components, injects nitrogen gas into the interior of the fixed housing via a one-way inlet pipe before insertion. Then, when the plug housing is inserted into the socket housing, the high-voltage terminal wire aligns with the high-voltage terminal piece. At this point, the high-voltage terminal piece contacts the rubber sleeve on the outer wall of the high-voltage terminal wire, causing the rubber sleeve to move the fixed plate and crossbar into the interior of the fixed housing. The crossbar then moves the sliding plate within the fixed housing, allowing the nitrogen gas inside to move through the circular hole to another area of ​​the fixed housing. When the sliding plate stops moving, it is elastically deformed by a first elastic element. This first elastic element causes the circular plate and sealing ring to seal the opening of the circular hole, preventing nitrogen gas from returning to another area inside the fixed housing during removal, thus improving the stability of the device. Furthermore, during insertion, as the sliding plate moves, it moves the connecting plate and elastic telescopic rod, which in turn moves the sealing ball. The sealing ball continuously seals the conical inner wall of the conical gas tube, preventing the flowing nitrogen gas from moving into the interior of the plug and socket housings, thus improving the accuracy of the device's anti-electric arcing.

[0018] This invention, through the cooperation of an anti-electric shock component and a stabilizing component, ensures that during insertion, the protruding rod aligns with the square hole. As the plug housing is pushed closer to the socket housing, the protruding rod slides along the inner wall of the arc-shaped hole, causing the rotating shell to rotate around the fixed rod. This rotating shell drives the locking plate to rotate to the top of the plug housing. Simultaneously, the sliding plate moves, pushing a moving plate inside the fixed shell. This moving plate then moves the connecting block in the anti-electric shock component, which in turn moves the second elastic element and the locking block. As the locking block moves, it contacts the side wall of the locking plate, thus locking the locking plate in place. This effectively creates a stable fixation between the plug housing and the socket housing, preventing the plug housing from loosening or falling off during use. It also prevents poor contact during device operation. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 9As shown, the present invention provides a high-voltage, high-current connector, including a working box 1 and a plug housing 2. A socket housing 3 is fixedly connected to the inner wall of the working box 1. High-voltage terminal pieces 4 are fixedly connected to both ends of one side of the inner wall of the socket housing 3. Protruding rods 5 are fixedly connected to both sides of the outer wall of the socket housing 3. The connector also includes:

[0031] The current connection mechanism 6 includes a fixing rod 62 fixedly connected to both sides of the outer wall of the plug housing 2. A rotating shell 63 is rotatably connected to one end of the outer wall of the fixing rod 62. A locking plate 61 is fixedly connected between the two rotating shells 63. An anti-electric component 64 is provided at one end of the plug housing 2 to prevent electric arc during insertion and removal. The anti-electric component 64 includes a fixing shell 642 fixedly connected to the inner wall of the plug housing 2 to contain nitrogen gas. A sliding plate 643 is slidably connected to the inner wall of the fixing shell 642 to push and inject nitrogen gas.

[0032] The anti-electric component 64 includes two high-voltage terminal wires 641 that penetrate one side wall of the plug housing 2. The outer wall of one end of the high-voltage terminal wire 641 is fixedly connected to the inner wall of the fixed housing 642. The outer wall of the fixed housing 642 is fixedly connected to the inner wall of the plug housing 2. A movable plate 644 is slidably connected to the bottom of the inner wall of the fixed housing 642.

[0033] A bent plate 645 is fixedly connected to one side of the movable plate 644. One end of the bent plate 645 passes through the fixed shell 642 and extends to the outside of the plug shell 2. A horizontal plate 646 is fixedly connected to the end of the bent plate 645 away from the movable plate 644. A connecting block 647 is fixedly connected to the top of one end of the horizontal plate 646. Both ends of one side of the fixed shell 642 are connected to a conical trachea 648.

[0034] Using the above scheme: the sliding plate 643 pushes the nitrogen gas inside the fixed shell 642 into the conical gas tube 648. The nitrogen gas enters the socket shell 3 and plug shell 2 through the conical gas tube 648. The chemical stability of nitrogen gas effectively suppresses the generation of electric arc and consumes electric arc energy, preventing equipment damage. When the high-voltage terminal 4 is separated from the high-voltage terminal line 641, the injection of nitrogen gas can quickly consume the electric arc energy and prevent the electric arc from damaging the equipment.

[0035] like Figures 1 to 9 As shown, a protective component 65 is provided at one end of the high-voltage terminal line 641. The protective component 65 includes a rubber sleeve 651 that is slidably connected to the outer wall of one end of the high-voltage terminal line 641. Two rubber sleeves 651 are provided, and a fixing plate 652 is fixedly connected between the two rubber sleeves 651. A crossbar 653 is fixedly connected to one side of the fixing plate 652.

[0036] The above solution is adopted: the rubber sleeve 651 is made of rubber, which is an insulator. When the insertion is performed, it can prevent the high-voltage terminal wire 641 from contacting the high-voltage terminal piece 4 and prevent damage to the device.

[0037] The end of the crossbar 653 away from the fixed plate 652 is fixedly connected to the side wall of the sliding plate 643. A compression spring 654 is fixedly connected to the side of the crossbar 653 near the fixed plate 652. One end of the compression spring 654 is fixedly connected to the outer wall of the fixed shell 642. Four first elastic elements 655 are respectively slidably connected through one side of the sliding plate 643.

[0038] Using the above scheme: When pulling out the device using the squeezing force of the compression spring 654, the compression spring 654 drives the fixed plate 652 and the crossbar 653 to move. The crossbar 653 drives the sliding plate 643 to move inside the fixed shell 642, allowing the nitrogen gas inside the fixed shell 642 to enter the conical gas tube 648, facilitating the discharge of nitrogen gas into the plug shell 2 and the socket shell 3, thus improving the anti-arc effect.

[0039] Two first elastic elements 655 are arranged in a group. One end of the first elastic element 655 is fixedly connected to a circular plate 656. A sealing ring 657 is fixedly connected to the side of the circular plate 656 near the first elastic element 655. Two circular holes 658 are respectively opened on the side of the sliding plate 643 near the first elastic element 655.

[0040] Using the above solution: the sealing ring 657 has a sealing effect, which can prevent nitrogen from resetting and flowing inside the round hole 658, and facilitate subsequent nitrogen anti-arc work.

[0041] The side wall of the sliding plate 643 is provided with a stabilizing component 66. The stabilizing component 66 includes a connecting plate 661 fixedly connected to both ends of one side of the sliding plate 643. An elastic telescopic rod 662 is fixedly connected to the side of the connecting plate 661 away from the sliding plate 643. The elastic telescopic rod 662 is located inside the conical air tube 648.

[0042] A sealing ball 663 is fixedly connected to the end of the elastic telescopic rod 662 away from the connecting plate 661. The outer wall of the sealing ball 663 contacts the inner wall of one end of the cone-shaped air tube 648. A second elastic element 664 passes through one side of the connecting block 647.

[0043] One end of the second elastic element 664 is fixedly connected to a locking block 665. The locking plate 61 has a strip groove 667 on the side near the rotating shell 63, and a square hole 668 is opened on the outer wall of the rotating shell 63.

[0044] One end of the square hole 668 is connected to an arc-shaped hole 669. One side of the arc-shaped hole 669 is opened on one side of the rotating shell 63. The end of the plug shell 2 near the high-voltage terminal line 641 is connected to a one-way air inlet pipe 660. One end of the one-way air inlet pipe 660 is connected to the inner wall of the fixed shell 642.

[0045] The above scheme is adopted: the design of the one-way air inlet pipe 660 ensures that gas can only enter the pipe and cannot leak or flow out of the pipe, so that nitrogen gas is injected into the interior of the fixed shell 642 through the one-way air inlet pipe 660.

[0046] The working principle and usage process of this invention are as follows: Before insertion, nitrogen gas is injected into the interior of the fixing shell 642 through the one-way inlet pipe 660. Then, when the plug shell 2 is inserted into the socket shell 3, the high-voltage terminal wire 641 is connected to the high-voltage terminal piece 4. At this time, the high-voltage terminal piece 4 will contact the rubber sleeve 651 on the outer wall of the high-voltage terminal wire 641, causing the rubber sleeve 651 to move the fixing plate 652 and the crossbar 653 into the interior of the fixing shell 642. The crossbar 653 drives the sliding plate 643 to slide, allowing the nitrogen gas inside the fixing shell 642 to move through the round hole 658 to another area of ​​the fixing shell 642. When the sliding plate 643 stops moving... Due to the elastic deformation of the first elastic element 655, the first elastic element 655 drives the circular plate 656 and the sealing ring 657 to seal the opening of the circular hole 658, preventing nitrogen from returning to another area inside the fixed shell 642 during the pulling process, thus improving the stability of the device. During the insertion process, when the sliding plate 643 moves, the sliding plate 643 drives the connecting plate 661 and the elastic telescopic rod 662 to move. The elastic telescopic rod 662 drives the sealing ball 663 to move. The sealing ball 663 will continuously seal the conical inner wall of the conical gas tube 648, preventing the flowing nitrogen from moving into the interior of the plug shell 2 and the socket shell 3, thus improving the accuracy of the device's anti-arc function.

[0047] During insertion, the protruding rod 5 aligns with the square hole 668. As the plug housing 2 is pushed closer to the socket housing 3, the protruding rod 5 slides along the inner wall of the arc-shaped hole 669, causing the rotating shell 63 to rotate around the fixed rod 62. The rotating shell 63 drives the locking plate 61 to rotate to the top of the plug housing 2. Simultaneously, as the sliding plate 643 moves, it contacts the moving plate 644 inside the fixed shell 642, pushing the moving plate 644 to move. The moving plate 644 drives the bent plate 645 and the horizontal plate 646 to move. The horizontal plate 646 drives the connecting block 647 to move. The connecting block 647 drives the second elastic element 664 and the locking block 665 to move. When the locking block 665 moves, it contacts the side wall of the locking plate 61, thus locking the locking plate 61. This effectively forms a stable fixation between the plug housing 2 and the socket housing 3, preventing the plug housing 2 from loosening or falling off during use. To prevent poor contact during use of the device.

[0048] When the plug housing 2 is pulled out, the connecting block 647 is first pushed towards the working box 1. The connecting block 647 drives the horizontal plate 646 and the bent plate 645 to move. The bent plate 645 drives the moving plate 644 to push the sliding plate 643, causing the sliding plate 643 to push the nitrogen gas inside the fixed shell 642 into the conical gas inlet pipe 648. The nitrogen gas then enters the socket housing 3 and the plug housing 2 through the conical gas inlet pipe 648. The chemical stability of nitrogen gas effectively suppresses the generation of electric arcs and consumes arc energy, preventing equipment damage. When the high-voltage terminal 4 is separated from the high-voltage terminal line 641, the injection of nitrogen gas can quickly consume the arc energy, preventing the arc from damaging the equipment. Furthermore, the injection of gas can inflate the internal areas of the socket housing 3 and the plug housing 2, reducing the mechanical stress during pull-out and helping to improve the durability and reliability of the equipment.
