Abstract

The invention discloses a transformer winding bobbin. The transformer winding bobbin comprises a primary end, a secondary end and a winding shaft, wherein the primary end and the secondary end are fixed on two opposite sides of the upper end of the winding shaft respectively; a plurality of PIN seats are fixed to each of the primary end and the secondary end; a plurality of first lead wire grooves are formed in the outer surface of each of the primary end and the secondary end; a lower baffle is arranged at the lower end of the winding shaft; a tail wire lead-down groove is formed in the lower baffle; a hook block is arranged in the tail wire lead-down groove; a tail wire of a wire group is pulled out of the tail wire lead-down groove formed in the lower baffle; and the tail wire is wound around the hook block to be fixed, so that the tail wire does not need to be buried in a copper coil, a short circuit is difficultly caused, the safety performance of the wire group is improved, a winding mode is improved, automated winding can be realized, and the assembling processing efficiency is improved.

Description

technical field

[0001] The invention relates to the field of electrical equipment, in particular to a low-power high-frequency transformer, in particular to a transformer winding skeleton. Background technique

[0002] The high-frequency transformer is the most important part of the switching power supply. The transformer skeleton is the main structural part of the electronic transformer. Its main function is to provide winding space for the shielding winding in the transformer, and the insulation performance of the transformer shielding winding is to affect the transformer. important factor in job performance. Originally, the tail wires of transformer shielding windings were usually cut and buried in the copper wire package in order to fix them conveniently. Operators were required to insert the tail wires. However, this method of embedding wires cannot be automated, and the operation is inconvenient and takes a lot of man-hours, which greatly affects The processing effici...
