When the plug 8 is plugged into the plug interface 3, it may be affected by vibration and gravity during use, causing the plug 8 to loosen at the plug interface 3, affecting the use of the inverter body 1. The overall idea is as follows: a high-voltage electrical interface for the inverter includes an inverter body 1, a plug interface 3 and a plug 8. The number of the plug interfaces 3 is at least two, each of which is electrically connected to the side end of the inverter body 1, and the plug 8 is plugged into the inner side wall of the plug interface 3.

After completing the adjustment of the inverter body 1, the user can plug the plug 8, and the user can insert the plug 8 into the plug interface 3. When the plug 8 approaches the plug interface 3, when the plug 8 contacts the limiting plate 41, the two limiting plates 41 will be pushed away from each other.

The two limiting plates 41 move and reset to limit the plug 8, so that when the support is used, the plug 8 is always firmly plugged into the inner wall of the plug interface 3 to limit the plug 8. When the user needs to pull out the plug 8, the user only needs to press the push column 37 to move downward, and the downward movement of the push column 37 will drive the push block 35 to move downward. At this time, the L-shaped pressure rods 43 on both sides will be pushed away from each other, and the two L-shaped pressure rods 43 will move away from each other, which will drive the baffles 4 on both sides to move away from each other, and then drive the limiting plates 41 on both sides to move away from each other, and the plug 8 will no longer be limited, and the user can pull out the plug 8;

[0029] A push column 37 is fixedly installed on the upper end of each push block 35, a cylindrical groove 34 is penetrated through the upper end of each vertical rod 33, each push column 37 is slidably installed on the inner side wall of the cylindrical groove 34, a third spring 36 is fixedly installed between each push column 37 and the vertical rod 33, and the end of each push block 35 is a chamfered surface.

The temperature detector 2 fixed at the side end of the inverter body 1 will perform real-time detection of the temperature of the inverter body 1 when it is working. When the temperature of the inverter body 1 exceeds a certain threshold, the temperature detector 2 will start the wires 21 on both sides through the two heat dissipation fans 22. The start of the wires 21 will dissipate heat for the inverter body 1, so as to avoid the inverter body 1 from being overheated and affecting its use;

[0030] The adjustment mechanism includes a base 6, a rectangular cross plate 7, a fixed block 12 and a pull rod 5. The base 6 is located below the inverter body 1. Support rods 64 are fixedly installed on both side ends of the base 6. Rotating shafts 13 are fixedly installed on both side ends of the inverter body 1. The side ends of the two support rods 64 are penetrated with circular grooves 65. The two rotating shafts 13 are rotatably installed on the inner side walls of the circular grooves 65. Two rectangular blocks 14 are fixedly installed on the circumferential end of the rotating shaft 13 on one side. The side ends of the two rectangular blocks 14 are penetrated with through grooves 15.

Suction cups 71 are fixedly mounted on the lower ends of the two rectangular cross plates 7. When the user inserts the plug 8, the user can first limit and fix the inverter body 1 according to the use requirements on site. The user can rotate the threaded rod 74. The threaded rod 74 rotates through the threaded groove 72 to drive the connecting rod 73 to move downward. The connecting rod 73 moves downward to drive the two rectangular cross plates 7 to move downward in the second rectangular groove 61. When the rectangular cross plate 7 moves downward to drive each suction cup 71 on the rectangular cross plate 7 to leave the inner side wall of the second rectangular groove 61, the user can stop rotating the threaded rod 74. The user can press the suction cup 71 to adsorb on a plane according to the use requirements. In some specific use environments, the plane may be a vertical or inclined surface.

The user can pull the pull rod 5, and the pull rod 5 moves to drive the two plug rods 51 to move. The second spring 52 is stretched, and when the insertion rod 51 is driven to leave the inner wall of the limiting groove 66, the user can rotate the pull rod 5, and the rotation of the pull rod 5 drives the insertion rod 51 to rotate. The rotation of the insertion rod 51 drives the rectangular block 14 to rotate through the through groove 15, and the rotation of the rectangular block 14 drives the inverter body 1 to rotate through the rotating shaft 13. After adjusting the angle of the inverter body 1, the user can stop rotating the pull rod 5. The user can release the pull rod 5. At this time, the second spring 52 will rebound and drive the insertion rod 51 to move and reset. The insertion rod 51 will be inserted into the inner wall of the limiting groove 66 again, completing the fixed adjustment of the inverter body 1.

[0032] In view of the problems existing in the prior art, the present invention provides a high-voltage electrical interface for a frequency converter. The device is provided with a baffle 4, a limit plate 41 and a first spring 42, and when the plug 8 is inserted into the plug-in interface 3, the first springs 42 on both sides pull the baffle 4 to drive the limit plates 41 to move, so that the two limit plates 41 limit the plug 8 plugged into the plug-in interface 3, ensuring that the plug 8 is always firmly plugged into the plug-in interface 3, and preventing the plug 8 from loosening and affecting the use of the frequency converter body 1:

[0033] Working principle:

[0034] In the first step, when the user plugs in the plug 8, he can first limit and fix the inverter body 1 according to the on-site usage requirements. The user can rotate the threaded rod 74, and the threaded rod 74 rotates through the threaded groove 72 to drive the connecting rod 73 to move downward. The connecting rod 73 moves downward to drive the two rectangular cross plates 7 to move downward in the second rectangular groove 61. When the rectangular cross plate 7 moves downward to drive each suction cup 71 on the rectangular cross plate 7 to leave the inner side wall of the second rectangular groove 61, the user can stop rotating the threaded rod 74. The user can press the suction cup 71 to adsorb on the plane according to the usage requirements. In some specific usage environments, the plane may be a vertical or inclined surface. At this time, the user needs to adjust the angle of the inverter body 1. , so that it can adapt to the insertion of the plug 8, the user can pull the pull rod 5, the movement of the pull rod 5 drives the two plug rods 51 to move, at this time the second spring 52 is stretched, when the plug rod 51 is driven to leave the inner wall of the limit groove 66, at this time the user can rotate the pull rod 5, the rotation of the pull rod 5 drives the plug rod 51 to rotate, the rotation of the plug rod 51 drives the rectangular block 14 to rotate through the through groove 15, the rotation of the rectangular block 14 drives the inverter body 1 to rotate through the rotating shaft 13, after adjusting the angle of the inverter body 1, the user can stop rotating the pull rod 5, the user can release the pull rod 5, at this time the second spring 52 will rebound and drive the plug rod 51 to move and reset, the plug rod 51 will be inserted into the inner wall of the limit groove 66 again, completing the fixed adjustment of the inverter body 1;

[0035] In the second step, after completing the adjustment of the inverter body 1, the user can plug the plug 8. The user can insert the plug 8 into the plug-in interface 3. When the plug 8 approaches the plug-in interface 3, the plug 8 contacts the limit plate 41, which pushes the two limit plates 41 away from each other. At this time, the baffles 4 on both sides will move away from each other, and the first spring 42 will be stretched by the force. After the plug 8 is fully inserted into the plug-in interface 3, the first spring 42 will rebound and pull the baffles 4 on both sides closer to each other. At this time, the two limit plates 41 are close to each other, and the two limit plates 41 move back. The plug 8 is limited in position, so that when the support is used, the plug 8 is always firmly plugged into the inner side wall of the plug interface 3 to limit the plug 8. When the user needs to pull out the plug 8, the user only needs to press the push column 37 to move downward, and the push column 37 moves downward to drive the push block 35 to move downward. At this time, the L-shaped pressure rods 43 on both sides are pushed away from each other, and the two L-shaped pressure rods 43 move away from each other to drive the baffles 4 on both sides to move away from each other, and then drive the limiting plates 41 on both sides to move away from each other, and the plug 8 is no longer limited, and the user can pull out the plug 8;

[0036] In the third step, when the plug 8 is connected to the socket 3 on the inverter body 1 for use, it will generate more heat during operation. The temperature detector 2 fixed on the side end of the inverter body 1 will perform real-time detection of the temperature of the inverter body 1 during operation. When the temperature of the inverter body 1 exceeds a certain threshold, the temperature detector 2 will start the wires 21 on both sides through two cooling fans 22. The start of the wires 21 will dissipate heat for the inverter body 1 to prevent the inverter body 1 from being overheated and affecting its use.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
