Piezoelectric transformer device and housing for piezoelectric transformer and method of manufacturing them

1. Field of the Invention A housing having lead frames which are protruded to contact and to resiliently support a piezoelectric transformer and a method of manufacturing the housing is disclosed. The housing has an upper housing part having at least two first lead frames protruded to resiliently contact input and output portions of an upper surface of the piezoelectric transformer, and a lower housing part having at least two second lead frames protruded to resiliently come into contact with the input and output portions of a lower surface of the piezoelectric transformer. The first and second lead frames are outwardly extended from the upper and lower housing parts, and the piezoelectric transformer is received in the upper and lower housing parts such that the piezoelectric transformer is resiliently supported by the first and second lead frames. By integral construction of the housing and the lead frames of the piezoelectric transformer, the housing affords easy contact with the transformer and prevention of breakage of the contact.
