<p>A kind of electronic transformer used in low-voltage lamps mainly includes case, electronic control circuit, voltage switch isolating transformer. Therein, the case consists of upper cover plate (1) and lower cover plate (2). The electronic control circuit and the magnetic core loop (6) of voltage switch isolating transformer are put between the upper cover plate (1) and lower cover plate (2). The outside of lower cover plate (2) provides grooves(9) adapting to coil winding, corresponding overline hole (10) and center hole (12) of lower cover plate. The winding of voltage switch isolating transformer is inlayed into the grooves (9) through the center hole (12) of lower cover plate, overline hole (10) and center hole of magnetic core loop (6). Then button up upper cover plate (1) and lower cover plate (2). This kind of transformer is portable, thin, beautiful, convenient, with better heat dispersion, and up to the correlative international safety standard.</p> |
