Claims

[Claims for Utility Model Registration] (1) A main body including a magnetic core around which a primary coil and a coil forming a secondary coil are wound with a predetermined number of turns; A plurality of terminals that are connected electrically and mechanically and are attached to a printed circuit board are formed to protrude from an end surface portion of the lower part of the main body to which the plurality of terminals are fixed, and the protrusion height is equal to that of the coil and the plurality of terminals. The printed circuit board is held between a protrusion having a height higher than a height of a connection portion with a terminal and a protruding end of the protrusion provided on each of the plurality of terminals when attached to the printed circuit board. A small transformer characterized by having a positioning means for positioning the transformer. (2) The protruding portion has a side end portion that comes into contact with the connection portion between the coil and the terminal.
The small transformer described in section. (3) The small transformer according to claim 1, wherein the positioning means is a bent portion that passes through the terminal mounting hole provided in the printed circuit board while coming into contact with the terminal mounting hole. (4) The small transformer according to claim 1, wherein the positioning means is a dipping portion that passes through the terminal mounting hole provided in the printed circuit board while coming into contact with the terminal mounting hole.
