MOUNTING STRUCTURE OF TRANSFORMER ON PRINTED BOARD

摘要

PURPOSE:To reduce the vibration level of a transformer main body by a method wherein the transformer main body is mounted on a printed board via a buffer material. CONSTITUTION:A transformer main body 1 is constituted by mounting a core 4 in a bobbin 3 wound with a coil 2. A buffer material 6 is mounted on a printed board 5 via a bonding agent and the main body 1 is mounted on this material 6. There, in the case where a current is made to flow through the main body 1, the current is made to flow through the coil 2 and the bobbin 3 and the core 4 are vibrated. This vibration noise of the main body 1 is not transmitted to the board 5 and can be reduced to a vibration level which is audibly caused no problem.
