TRANSFORMER

摘要

PURPOSE: A transformer is provided to implement electric connection with an external conductor without a separate connector by employing a detachable connecting part. CONSTITUTION: A bobbin(10) includes a coil winding part(2) for winding a coil(20). The coil winding part has a through hole(2a) for insertion of a core(30) forming a magnetic path, a primary winding part(2b) for winding a primary coil(22), a secondary winding part(2c) for winding a secondary coil(23), and insulating partition(2d) formed between the primary and secondary winding parts. A connecting part(40) is detachably attached into an insertion groove formed in the bobbin. The insertion groove has a coupling projection corresponding to a coupling groove formed in the connecting part.
