This application relates to a frequency converter unit, a frequency converter, and industrial
control equipment. The frequency converter unit includes: a
capacitor body, a bottom shell, a
signal connector, and a cable connection
assembly. The
capacitor body includes an upper shell and a
capacitor. The capacitor is disposed inside the upper shell, and a cavity is formed between the capacitor and the upper shell. The bottom shell has a mounting cavity. The bottom shell is detachably connected to the bottom of the upper shell. The
signal connector is disposed on the upper shell and is positioned corresponding to the cavity. The cable connection
assembly is disposed on the bottom shell and is positioned corresponding to the mounting cavity. The
signal connector and the cable connection
assembly are located on the same side of the outer shell. This utility model has the
advantage of solving the problem of
signal lines and output cables crossing and overlapping, and reducing the
failure rate of the frequency converter.
