[0001] The invention belongs to the technical field of connectors, in particular to a high-voltage and high-current connector. Background Art

[0002] High-voltage, high-current connectors are used in power systems and equipment. They are electronic components that connect two active devices.

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

[0009] Preferably, one end of the cross bar away from the fixed plate is fixedly connected to the side wall of the sliding plate, the side of the cross bar close to the fixed plate is fixedly connected to a compression spring, one end of the compression spring is fixedly connected to one side of the outer wall of the fixed shell, and one side of the sliding plate is respectively penetrated and slidably connected with four first elastic members.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a combination of anti-electric components. When the plug housing is pulled out, the connecting block is first pushed toward the working box. During the movement of the connecting block, the sliding plate is pushed, causing the sliding plate to push nitrogen inside the fixed shell into the interior of the cone head air pipe. The nitrogen enters the interior of the socket housing and the plug housing through the cone head air pipe, effectively suppressing the generation of arcs by utilizing the chemical stability of nitrogen. When the high-voltage terminal piece is separated from the high-voltage terminal line, the injection of nitrogen can quickly consume the arc energy and prevent the arc from damaging the equipment. The gas injection can also inflate the internal areas of the socket housing and the plug housing, reducing the mechanical stress during extraction, which helps to improve the durability and reliability of the equipment.

[0016] The present invention cooperates with an anti-electric component, a protective component, and a stabilizing component. Before insertion, nitrogen is injected into the interior of the fixed shell through a one-way air inlet pipe. Subsequently, when the plug shell is inserted into the socket shell, the high-voltage terminal wire is docked with the high-voltage terminal piece. At this time, the high-voltage terminal piece contacts the rubber sleeve on the outer wall of the high-voltage terminal wire, causing the rubber sleeve to drive the fixed plate and the cross bar to move into the interior of the fixed shell. The cross bar drives the sliding plate to slide inside the fixed shell, causing the nitrogen inside the fixed shell to move through the circular hole to another area of the fixed shell. When the sliding plate stops moving, it is elastically deformed by the first elastic member. The first elastic member drives the circular plate and the sealing ring to seal the opening of the circular hole, preventing nitrogen from returning to another area inside the fixed shell during removal, thereby improving the stability of the device. During the insertion process, when the sliding plate moves, the sliding plate drives the connecting plate and the elastic telescopic rod to move. The elastic telescopic rod drives the sealing ball to move. The sealing ball continuously blocks the conical inner wall of the cone head air pipe, preventing the circulating nitrogen from moving into the interior of the plug shell and the socket shell, thereby improving the accuracy of the device's arc protection.

[0017] The present invention provides a combination of an anti-electricity component and a stabilizing component. During the insertion process, the protruding rod is docked with the square hole. At this time, the plug housing is continuously pushed toward the socket housing. The protruding rod slides along the inner wall of the arc hole, causing the rotating shell to rotate around the fixed rod. The rotating shell drives the locking plate to rotate to the top of the plug housing. At this time, when the sliding plate moves, the sliding plate pushes the moving plate inside the fixed shell. The moving plate drives the connecting block in the anti-electricity component to move. The connecting block drives the second elastic member and the locking block to move. When the locking block moves, it contacts the side wall of the locking plate, thereby locking the locking plate. This can effectively form a stable fixation between the plug housing and the socket housing, preventing the plug housing from loosening or falling off during use. The device prevents poor contact during use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 9 As shown, the present invention provides a high-voltage and high-current connector, comprising a working box 1 and a plug housing 2, wherein the inner wall of the working box 1 is fixedly connected to a socket housing 3, and high-voltage terminal pieces 4 are fixedly connected to both ends of one side of the inner wall of the socket housing 3, and protruding rods 5 are fixedly connected to both sides of the outer wall of the socket housing 3, and further comprising; The current connection mechanism 6 includes a fixed rod 62 fixedly connected to both sides of the outer wall of the plug housing 2, and the outer wall of one end of the fixed rod 62 is rotatably connected to a rotating shell 63, and 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 arcs from occurring during the plugging and unplugging process. The anti-electric component 64 includes a fixed shell 642 fixedly connected to the inner wall of the plug housing 2 for accommodating nitrogen. The inner wall of the fixed shell 642 is slidably connected to a sliding plate 643 for pushing and injecting nitrogen.

[0022] The anti-electric component 64 includes two high-voltage terminal wires 641 that pass through the side wall of one end 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 shell 642. The outer wall of the fixed shell 642 is fixedly connected to the inner wall of the plug housing 2. The bottom of the inner wall of the fixed shell 642 is slidably connected to a movable plate 644.

[0023] 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, and the end of the bent plate 645 away from the movable plate 644 is fixedly connected to a horizontal plate 646, and the top of one end of the horizontal plate 646 is fixedly connected to a connecting block 647, and both ends of one side of the fixed shell 642 are connected to a cone-shaped air pipe 648.

[0024] The above scheme is adopted: the sliding plate 643 pushes the nitrogen inside the fixed shell 642 into the interior of the cone head air pipe 648, and the nitrogen enters the interior of the socket shell 3 and the plug shell 2 through the cone head air pipe 648. The chemical stability of nitrogen is used to effectively suppress the generation of arcs and consume arc energy to prevent equipment damage. When the high-voltage terminal piece 4 is separated from the high-voltage terminal wire 641, the injection of nitrogen can quickly consume the arc energy to prevent the arc from damaging the equipment.

[0025] like Figures 1 to 9 As shown, a protective component 65 is provided at one end of the high-voltage terminal wire 641. The protective component 65 includes a rubber sleeve 651 slidably connected to the outer wall of one end of the high-voltage terminal wire 641. Two rubber sleeves 651 are provided. A fixing plate 652 is fixedly connected between the two rubber sleeves 651, and a cross bar 653 is fixedly connected to one side of the fixing plate 652.

[0026] The above solution is adopted: the rubber sleeve 651 is made of rubber, which is an insulator. During the insertion operation, it can prevent arcing when the high-voltage terminal wire 641 contacts the high-voltage terminal piece 4, thereby preventing damage to the device.

[0027] One end of the cross bar 653 away from the fixed plate 652 is fixedly connected to the side wall of the sliding plate 643, and the side of the cross bar 653 close to the fixed plate 652 is fixedly connected to the extrusion spring 654. One end of the extrusion spring 654 is fixedly connected to one side of the outer wall of the fixed shell 642. Four first elastic members 655 are respectively passed through and slidably connected to one side of the sliding plate 643.

[0028] With the above solution, when the extraction operation is performed, the extrusion spring 654 drives the fixed plate 652 and the cross bar 653 to move through the extrusion force of the extrusion spring 654, and the cross bar 653 drives the sliding plate 643 to move inside the fixed shell 642, so that the nitrogen inside the fixed shell 642 enters the interior of the cone head air pipe 648, making it easier for the nitrogen to be discharged into the interior of the plug housing 2 and the socket housing 3, thereby improving the arc protection effect.

[0029] The two first elastic members 655 are arranged in a group. One end of a group of first elastic members 655 is fixedly connected to a circular plate 656. A sealing ring 657 is fixedly connected to the side of the circular plate 656 close to the first elastic member 655. Two circular holes 658 are respectively provided on the side of the sliding plate 643 close to the first elastic member 655.

[0030] With the above solution, the sealing ring 657 has a sealing effect, which can prevent the nitrogen from resetting and flowing inside the circular hole 658, thereby facilitating the subsequent arc prevention work of the nitrogen.

[0031] A stabilizing assembly 66 is provided on the side wall of the sliding plate 643. The stabilizing assembly 66 includes a connecting plate 661 fixedly connected to both ends of one side of the sliding plate 643. The side of the connecting plate 661 away from the sliding plate 643 is fixedly connected to an elastic telescopic rod 662, and the elastic telescopic rod 662 is provided inside the cone head air pipe 648.

[0032] The end of the elastic telescopic rod 662 away from the connecting plate 661 is fixedly connected to a sealing ball 663 , the outer wall of the sealing ball 663 contacts the inner wall of one end of the cone head air pipe 648 , and a second elastic member 664 passes through one side of the connecting block 647 .

[0033] One end of the second elastic member 664 is fixedly connected to a clamping block 665 . A strip groove 667 is formed on one side of the clamping plate 61 close to the rotating shell 63 . A square hole 668 is formed on one side of the outer wall of the rotating shell 63 .

[0034] 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 , and one end of the plug shell 2 close to the high-voltage terminal line 641 is connected to a one-way air intake pipe 660 , and one end of the one-way air intake pipe 660 is connected to the inner wall of the fixed shell 642 .

[0035] The above solution is adopted: the design of the one-way air inlet pipe 660 allows gas to only enter the pipe and not leak or flow out of the pipe, so that nitrogen is injected into the interior of the fixed shell 642 through the one-way air inlet pipe 660 .

[0036] The working principle and usage process of the present invention are as follows: before insertion, nitrogen is injected into the interior of the fixed shell 642 through the one-way air inlet pipe 660, and then when the plug shell 2 is inserted into the interior of the socket shell 3, the high-voltage terminal wire 641 is docked with the high-voltage terminal piece 4. At this time, the high-voltage terminal piece 4 will come into contact with the rubber sleeve 651 on the outer wall of the high-voltage terminal wire 641, so that the rubber sleeve 651 drives the fixed plate 652 and the cross bar 653 to move toward the interior of the fixed shell 642, and the cross bar 653 drives the sliding plate 643 to slide, so that the nitrogen inside the fixed shell 642 moves to another area of the fixed shell 642 through the circular hole 658. When the sliding plate 643 is no longer moving, Due to the elastic deformation of the first elastic member 655, the first elastic member 655 drives the circular plate 656 and the sealing ring 657 to seal the opening of the circular hole 658, thereby preventing the nitrogen from returning to another area inside the fixed shell 642 during the removal process, thereby improving the stability of the device. In addition, 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, and the elastic telescopic rod 662 drives the sealing ball 663 to move. The sealing ball 663 will continue to seal the conical inner wall of the cone head air pipe 648, thereby preventing the circulating nitrogen from moving into the interior of the plug housing 2 and the socket housing 3, thereby improving the accuracy of the device's arc protection.

[0037] During the insertion process, the protruding rod 5 is docked with the square hole 668. At this time, the plug housing 2 continues to be pushed toward the socket housing 3. The protruding rod 5 will slide along the inner wall of the arc 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. At the same time, during the movement of the sliding plate 643, the sliding plate 643 will contact the movable plate 644 inside the fixed shell 642 and push the movable plate 644 to move. The movable plate 644 drives the bent plate 645 and the cross plate 646 to move. The cross plate 646 drives the connecting block 647 to move. The connecting block 647 drives the second elastic member 664 and the locking block 665 to move. When the locking block 665 moves, it will contact the side wall of the locking plate 61, thereby locking the locking plate 61, which can effectively form a firm fixation between the plug housing 2 and the socket housing 3, preventing the plug housing 2 from loosening or falling off during use. Prevent the device from having poor contact during use.

[0038] When the plug housing 2 is pulled out, the connecting block 647 is first pushed toward 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 movable plate 644 to push the sliding plate 643, so that the sliding plate 643 pushes the nitrogen inside the fixed shell 642 into the interior of the cone head air pipe 648. The nitrogen enters the interior of the socket housing 3 and the plug housing 2 through the cone head air pipe 648. The chemical stability of nitrogen is used to effectively suppress the generation of arcs and consume arc energy, thereby preventing damage to the equipment. When the high-voltage terminal piece 4 is separated from the high-voltage terminal line 641, the injection of nitrogen can quickly consume the arc energy and prevent the arc from damaging the equipment. In addition, the injection of gas can inflate the internal areas of the socket housing 3 and the plug housing 2, reducing the mechanical stress during extraction, which helps to improve the durability and reliability of the equipment.
