Description

Electronic transformer skeleton convenient to weld dress Technical Field The utility model relates to the technical field of electronic transformers, in particular to an electronic transformer framework convenient to weld. Background The electronic transformer has an electronic device for converting alternating voltage of mains supply into direct current and then forming a high-frequency alternating voltage output through a semiconductor switching device, an electronic element and a high-frequency transformer winding, and is also an alternating-current-direct-current-alternating-current inverter circuit taught in the electronics theory. In brief, it is mainly composed of a high-frequency transformer core (iron core) and two or more coils, which are not changed in position from one or more electric loops, and are converted into alternating voltage and current by alternating current power through electromagnetic induction. And at the output end of the high-frequency transformer, one or more than two power circuits are supplied with high-frequency alternating current or direct current with different voltage levels. The pin of current electronic transformer skeleton department is slice or needle structure, through inserting the pin to corresponding circuit board department, uses soldering to weld pin and transformer dress on the circuit board, and such transformer skeleton pin is comparatively smooth because its surface, therefore the pin when welding with the wire of coil and pin and circuit board welding, the adhesive force of soldering tin is not strong enough, the condition of rosin joint appears easily, influences the electronic transformer skeleton and welds on the circuit board quality, can't satisfy user's user demand.
