Abstract
A one-piece frame is provided for a core/coil assembly of a transformer. The frame includes a first wall, a second wall integral with the first wall, a third wall integral with the second wall and in opposing relation to the first wall, and a fourth wall integral with the third wall and in opposing relation to the second wall. Mounting structure secures the fourth wall to the first wall. The walls define a generally rectangular enclosure having open sides communicating with an interior space. The interior space is constructed and arranged to house at least a portion of a core/coil assembly of a transformer.
Claims9
A method of providing a frame and a core/coil assembly for a transformer, the method comprising the steps of:
- providing a linear, single piece of metal as a frame having first, second, and third notches disposed in spaced relation, the frame having opposing ends,
- bending a first portion of the frame about the first notch to define a first wall of the frame,
- bending a second portion of the frame about the second notch to define a second wall and a third wall of the frame and defining an opened end communicating with an interior space of the frame,
- moving the frame or the core/coil assembly so that the core/coil assembly is engaged by a surface of the second wall, with the core/coil assembly being disposed in the interior space, and
- bending a third portion of the frame about the third notch to define a fourth wall of the frame and to close the opened end, thereby defining a generally rectangular enclosure about a portion of the core/coil assembly having open sides, with the opposing ends of the frame being adjacent to each other.
