Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.
Referring to fig. 1 to 3, the present embodiment discloses a transformer convenient for alignment, which includes a transformer bobbin 100, a coil 200 and a magnetic core 300, wherein the transformer bobbin 100 has a hollow winding portion 110, a pin mounting portion 120 and a metal pin 130 bent in two directions, and two ends of the winding portion 110 are both provided with flanges 140; the pin mounting part 120 is arranged at the bottom of the rib 140, the bottom of the pin mounting part 120 is provided with a mounting hole (not shown) and a limiting groove 121, and the limiting groove 121 is communicated with the mounting hole and extends out of the edge of the pin mounting part 120; the first end 131 of the metal pin 130 is inserted into the mounting hole, the bent portion 132 of the metal pin 130 is nested in the limiting groove 121, the second end 133 of the metal pin 130 is located at the edge of the pin mounting part 120 and extends in the direction far away from the pin mounting part 120, and the coil 200 is wound on the outer side of the winding part 110; the magnetic core 300 is inserted at both sides of the winding part 110.
The metal pin 130 is a bidirectional bending structure, so that the second end 133 of the metal pin 130 is located at the edge of the pin mounting part 120 and does not exceed the edge of the pin mounting part 120, the occupied area of the transformer is not increased, the metal pin 130 can be prevented from being shielded by the pin mounting part 120, and alignment is facilitated when a circuit board is plugged in.
