With the rapid development of power systems and new energy fields, the performance requirements for such connectors are becoming increasingly higher.

[0003] In actual applications, the power cord of the connector is often twisted due to some external forces, such as improper operation during installation, vibration during equipment operation, or human error. If this twisting force is not effectively blocked, it will directly lead to damage to the connection position of the power cord and even cause more serious safety accidents, which is not conducive to stability and safety of use.

If this twisting force is not effectively blocked, it will directly lead to damage to the power cord connection position and even cause more serious safety accidents, which is not conducive to stability and safety of use.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-current power cord connector, comprising a fixed socket and a movable plug, wherein the movable plug is provided with pins, and the movable plug is plugged into the fixed socket through the pins, and the fixed socket is provided with an anti-twisting component, which is used to prevent the pins from being twisted and disconnected;

[0008] The anti-screwing assembly includes a fixed connecting plate, a fixed nut, a clamping block, a double-sided rack, a C-shaped fixing frame, a clamping column, a hexagonal sleeve and a nut sleeve;

[0009] The fixed connecting plate in the anti-twisting assembly is sleeved on the outer surface of the fixed socket, and a plurality of fixing pins are fixedly connected on both sides of the fixed connecting plate. The fixing pins are used to connect the fixed socket and the housing of the installed device, and the fixing nut is threadedly sleeved on the outer surface of the fixed socket;

[0010] The plurality of card blocks are respectively fixedly connected to the outer surface of the fixed connection plate, and two adjacent card blocks are arranged in a mirror image. The outer surfaces of the two adjacent card blocks are both provided with insertion holes.

[0012] Preferably, springs are fixedly connected between both sides of the C-shaped fixing frame and the hexagonal sleeve, and a plurality of clamping columns are fixedly connected to the outer surface of the gear respectively.

[0013] Preferably, the plurality of double-sided racks are fixedly connected to the lower surface of the hexagonal sleeve, and gears are meshed and connected to the teeth on both sides of the double-sided racks.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a high current power line connector with the following advantages:

[0018] 1. This high-current power cord connector drives the two gears and the clamping column thereon to rotate outward together through the double-sided rack until the angle of the clamping column matches the socket, and the clamping column will enter the socket. At this time, when the power cord of the movable plug is subjected to external twisting force, the force will be transmitted to the double-sided rack through the nut sleeve and the hexagonal sleeve, and the double-sided rack will transmit the force to the corresponding clamping column. Since the clamping column is tilted in the socket, the force can better act on multiple rotating shafts, so that the fixed connecting plate can receive the force, and when the fixed connecting plate is subjected to force, it will directly transmit the force to the casing of the installed device through multiple fixing pins. This ultimately allows the power cord to be blocked by the installation casing when it is subjected to torsional force, thereby avoiding damage to the power cord caused by the torsional impact force and improving the stability and safety of the connector.

[0019] 2. The high-current power cord connector is constructed by putting the fixed connecting plate of the connector on the fixed socket, then inserting the fixed socket into the installation hole, and then putting on the fixed connecting plate. At this time, the fixed socket can be driven to move upward by tightening the fixing nut. At this time, the fixed socket will move upward under the force of the fixing nut. At this time, the boss position of the fixed socket and the shell of the installed device will be close to each other. At this time, the fixing pin will be inserted into the installed shell to fix the boss of the fixed socket. This installation and fixing method avoids the problem that when a single thread is tightened and fixed in the traditional method, the power cord is driven by the external twisting force to drive the fixed connecting plate to rotate at the same time, causing the connecting wire in the fixed socket to twist and disconnect. This can improve the rotation stability of the fixed socket to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-3 The utility model provides a new technical solution: a high-current power cord connector, comprising a fixed socket 1 and a movable plug 3, wherein the movable plug 3 is provided with pins, and the movable plug 3 is plugged into the fixed socket 1 through the pins, and the fixed socket 1 is provided with an anti-twisting component, which is used to prevent the pins from being twisted and disconnected;

[0029] Furthermore, the anti-screwing assembly includes a fixed connecting plate 2, a fixing nut 5, a clamping block 6, a double-sided rack 7, a C-shaped fixing frame 8, a clamping column 11, a hexagonal sleeve 13 and a nut sleeve 14;

[0030] Furthermore, the fixed connecting plate 2 in the anti-twisting assembly is sleeved on the outer surface of the fixed socket 1, and a plurality of fixing pins 4 are fixedly connected on both sides of the fixed connecting plate 2. The fixing pins 4 are used to connect the fixed socket 1 and the housing of the installed device, and the fixing nut 5 is threadedly sleeved on the outer surface of the fixed socket 1;

[0031] Furthermore, a plurality of card blocks 6 are respectively fixedly connected to the outer surface of the fixed connection plate 2 , and two adjacent card blocks 6 are arranged in a mirror image, and the outer surfaces of the two adjacent card blocks 6 are both provided with a socket 16 .

[0032] Furthermore, the clamping column 11 is adapted to the corresponding jack 16 , the plug end of the movable plug 3 is fixedly connected to the hexagonal boss 15 , and the hexagonal sleeve 13 is slidably connected to the outer surface of the hexagonal boss 15 .

[0033] Furthermore, springs 12 are fixedly connected between the two sides of the C-shaped fixing frame 8 and the hexagonal sleeve 13 , and a plurality of clamping columns 11 are fixedly connected to the outer surface of the gear 10 .

[0034] Furthermore, a plurality of double-sided racks 7 are fixedly connected to the lower surface of the hexagonal sleeve 13 , and the gears 10 are meshed and connected to the teeth on both sides of the double-sided racks 7 .

[0035] Furthermore, the two gears 10 are both rotatably connected with a rotating shaft 9, the C-shaped fixing frame 8 is fixedly connected to the two rotating shafts 9, and the double-sided rack 7 is slidably connected to the middle end of the C-shaped fixing frame 8.

[0036] Furthermore, the nut sleeve 14 is threadedly sleeved on the outer surface of the movable plug 3, the hexagonal sleeve 13 is rotatably connected to the nut sleeve 14, and the nut sleeve 14 is used to drive the hexagonal sleeve 13 to move up and down.

[0037] Furthermore, when in use, the fixed connecting plate 2 of the connector is sleeved on the fixed socket 1, and then the fixed socket 1 is inserted into the installed hole, and then the fixed connecting plate 2 is sleeved. At this time, by tightening the fixing nut 5, the fixed socket 1 can be driven to move upward. At this time, the fixed socket 1 will move upward under the force of the fixing nut 5. At this time, the boss position of the fixed socket 1 and the shell of the installed device will be close to each other. At this time, the fixing pin 4 will be inserted into the installed shell to fix the boss of the fixed socket 1. This installation and fixing method avoids the problem that when a single thread is tightened and fixed in the traditional method, the power cord is subjected to the external twisting force to drive the fixed connecting plate 2 to rotate at the same time, causing the connecting wire in the fixed socket 1 to twist and disconnect. This can improve the rotation stability of the fixed socket 1 to a certain extent.

[0038] Furthermore, after the active plug 3 is inserted into the fixed socket 1, by screwing the nut sleeve 14, the nut sleeve 14 can drive the hexagonal sleeve 13 to move toward the fixed connecting plate 2 until the clamping column 11 can contact the corresponding clamping block 6. At this time, the spring 12 will be compressed until the double-sided rack 7 drives the two gears 10 and the clamping column 11 thereon to rotate outward together, until the angle of the clamping column 11 matches the socket 16, and the clamping column 11 will enter the socket 16. At this time, when the power cord of the active plug 3 is subjected to the external twisting force, the force will be transmitted to the double-sided rack 7 through the nut sleeve 14 and the hexagonal sleeve 13. On the double-sided rack 7, the double-sided rack 7 will transfer the force to the corresponding card column 11. Since the card column 11 is tilted in the socket 16, the force can be better applied to the multiple rotating shafts 9, so that the fixed connecting plate 2 can receive the force, and when the fixed connecting plate 2 is subjected to the force, it will directly pass through the multiple fixing pins 4 to transfer the force to the housing of the installed device. This ultimately makes the power cord when subjected to the torsional force. Its impact force can be blocked by the installation housing, which avoids the damage to the power cord caused by the torsional impact force and improves the stability and safety of the connector.

[0039] Working principle: When in use, the fixed connecting plate 2 of the connector is put on the fixed socket 1, and then the fixed socket 1 is inserted into the installed hole, and then the fixed connecting plate 2 is put on. At this time, by tightening the fixing nut 5, the fixed socket 1 can be driven to move upward. At this time, the fixed socket 1 will move upward under the force of the fixing nut 5. At this time, the boss position of the fixed socket 1 and the shell of the installed device will be close to each other. At this time, the fixing pin 4 will be inserted into the installed shell to fix the boss of the fixed socket 1.

[0040] Furthermore, after the movable plug 3 is inserted into the fixed socket 1, by screwing the nut sleeve 14, the nut sleeve 14 can drive the hexagonal sleeve 13 to move toward the fixed connecting plate 2 until the post 11 can contact the corresponding block 6. At this time, the spring 12 will be compressed until the double-sided rack 7 drives the two gears 10 and the post 11 thereon to rotate outward together, until the angle of the post 11 matches the socket 16, the post 11 will enter the socket 16. At this time, when the power cord of the movable plug 3 is subjected to external twisting force, the force will be transmitted to the double-sided rack 7 through the nut sleeve 14 and the hexagonal sleeve 13, and the double-sided rack 7 will transmit the force to the corresponding post 11. Since the post 11 is tilted in the socket 16, the force can better act on multiple rotating shafts 9, so that the fixed connecting plate 2 can receive the force.
