Abstract
The utility model relates to a keyboard assembly structure of a frequency converter comprising a keyboard, a keyboard bottom supporting plate, a cover plate, a keyboard support, a shielding plate, a keyboard control plate, and a pressing plate. The keyboard bottom supporting plate is connected with the keyboard support in a buckled manner. The bottom part of the keyboard support is provided with a second positioning pin, and the shielding plate is provided with a second positioning hole. The second positioning pin is inserted in the second positioning hole, and the diameter of the second positioning pin is smaller than the diameter of the second positioning hole. One end of the pressing plate is fixedly connected with the bottom part of the keyboard support, and the other end is movably connected with the shielding plate by a screw, and a certain gap is arranged between the pressing plate and the shielding plate. The keyboard control plate is fixedly connected with the bottom part of the keyboard support, and the keyboard is disposed on the keyboard bottom supporting plate, and is electrically connected with the keyboard control plate. The keyboard bottom supporting plate is connected with the keyboard support in a buckled manner, and during the maintenance, only the cover plate is required to be taken down for the maintenance. The keyboard control plate is directly disposed on the keyboard support, and is integrated with the keyboard support, and therefore the efficient and stable connection between the keyboard and the keyboard control plate can be formed.
