Abstract
A coil bobbin () that comprises a housing () with an interior () and including a floor () with at least one electrical lead-in () projecting through an aperture () in the floor. The lead-in () has one end () formed for attachment to a printed circuit board (). The electrical lead-in () has a given diameter Dand is provided with thermal-strain relief () positioned within the interior () of housing (). The aperture () has a diameter Dlarger than the given diameter Dof the lead-in. The larger diameter Dof the aperture allows free movement of the lead-in during thermal cycling and contributes to the desired result. This construction also allows the use of round lead-ins over the previously employed square lead-ins, which were required to provide the rigid interference fit previously necessary.
