Abstract
A choke-coil fixture for miniature motors of a type having choke coils housed in recesses formed in an end bell closing an end of a motor housing, characterized in that choke-coil housing recesses are formed in such a manner as to lock ends of the choke coils when the choke coils are inserted into the recesses in the longitudinal direction, terminals having flat portions for pushing the other ends of the choke coils at portions electrically connecting the lead ends of the choke coils, and engaging portions for locking to the end bell is disclosed. The terminals for miniature motors can have positioning portions for positioning the terminals with respect to the lead ends of the choke coils, and cylindrical portions for engaging with the connecting power-feeding connecting pins; the cylindrical portion adapted to be flexible in size by being plastically deformed. A choke-coil fixture for miniature motors having insulating washers for insulating the other lead ends from the terminals by engaging with the choke coils inserted into recesses for housing the choke coils is disclosed.
