Abstract
The utility model belongs to the technical field of variable-frequency transformers, and particularly relates to a variable-frequency transformer outlet pin structure which comprises a variable-frequency transformer, outlet pins are arranged on the variable-frequency transformer and sleeved with copper sleeves, and wire inlet grooves are formed in the side walls of the copper sleeves so that the outlet pins can be assembled in the copper sleeves conveniently. And the inner surface of the wire inlet groove is an arc surface, so that the wire outlet pin is prevented from being cut. The limiting assembly is used for preventing the wire inlet groove from becoming larger gradually, and the limiting assembly is arranged on the copper sleeve. The limiting assembly comprises a circular ring, the copper sleeve penetrates through the circular ring, the annular rubber pad is fixedly installed on the inner surface of the circular ring, and the inner surface of the annular rubber pad is in close contact with the outer surface of the copper sleeve. According to the utility model, the pin strength of the variable frequency transformer is improved, and the deformation resistance is stronger.
