Embodiment Construction

[0042] The technical content and detailed description of the present invention are now described as follows in conjunction with the accompanying drawings:

[0043] see figure 2 , a three-dimensional schematic diagram of the appearance of the winding frame of the transformer of the present invention. As shown in the figure: the transformer of the present invention has a winding frame 1, and the winding frame 1 has a winding part 11, and the winding part 11 has a perforation 12, and the perforation 12 is for iron The core (not shown in the figure) penetrates. The two ends of the through hole 12 of the winding portion 11 have two symmetrical bearing portions 13, and the two wings of the bearing portion 13 have symmetrical side portions 14, and the winding portion 11 is connected to the bearing portion 13 and the side portions 14. Form the assembly space 15 that can accommodate iron core to install between. In addition, there is a conductive pin 16 on one side of the side port...

Abstract

The invention discloses a transformer and an electronic device comprising the same. The electronic device comprises a circuit board and the transformer, and an opening is arranged on the circuit board. The transformer is provided with a winding frame arranged in the opening, and a winding portion for winding a coil is arranged on the winding frame. In addition, two ends of the winding portion are provided with two symmetrical bearing portions, two wings of each bearing portion are provided with symmetrical side portions, and an assembly space capable of containing an iron core is formed among the winding portion, the bearing portions and the side portions. Besides, a conductive pin is arranged on one side surface of each side portion, and a boss is arranged on the other side surface of each side portion and is arranged on the surface of the circuit board in a crossover manner, so that the overall height of the transformer mounted on the circuit board is adjusted or reduced by the bosses.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer capable of adjusting the mounting height on a circuit board. Background technique [0002] A transformer is a kind of power that can be converted from the outside into the working voltage required by the internal circuit board of the electronic device, so that the electronic device can operate normally. Therefore, the transformer is an indispensable and important electronic component for current electronic devices. [0003] When the traditional E-shaped iron core transformer is in use, the transformer is directly welded and stood on the surface of the circuit board, and the external power is input to the transformer, and the transformer converts the power into the working voltage required by the circuit board to make the circuit board work. Electronics are functioning normally. Since the transformer is mounted on the circuit board in a standing manner, it must have a certain heigh...
