Bobbin bracket structure of transformer

The invention discloses a structure for transformer bobbin bracket, which takes a shape of a hollow pipe body. A plurality of separators are arranged on the transformer bobbin bracket and at least one trans-line groove is arranged on the separator and used for providing space for the coil to cross the separator; the trans-line groove is designed to be slantingly tangent with the separator so as to increase the laying distance of the coil, and the depth of the trans-line groove presents a slant shape or ladder shape which is higher at one side and lower at the other side to ensure that the line of the coil enters at a higher position and goes out at a lower position when the lines of the coil are laid so as to increase the relative distance between two neighboring groups of coils of the separator, thereby effectively increasing the withstanding voltage of the separator of the bobbin bracket and relatively shortening the thickness of the separator of the bobbin bracket so as to further shorten the size of the t
