Abstract
A self-leaded, surface mountable component package is provided for holding a wide variety of electrical components having widely variant conductor wire sizes in a manner achieving standardized conductor contact positioning. The general box-like configuration provides for component style variability and has a set of progressively stepped or tapered winding bosses to position and secure component conductors of multiple wire size, thereby ensuring proper registration with conductive traces of surface mount printed circuit boards and substrates.

A self-leaded surface mount component holder comprising:
- a unitary housing formed of a plastic material for containing a particular electrical component,
- the housing including a substantially planar top wall portion and at least two sidewall portions depending downwardly from opposite edge regions of the top wall portion thereby defining a component cavity for receiving an electrical component therein,
- a plurality of winding bosses extending outwardly from each sidewall portion and including bottom faces lying in a bottom plane substantially parallel with a plane of the top wall portion,
- each winding boss also including an outer wall segment including an outer winding post projecting upwardly from a bottom segment including the bottom face and an inner wall segment, interior faces of the outer wall segment and the inner wall segment lying in converging planes in a direction substantially normal to the bottom plane and defining an interior groove being sized to receive and clinch a component connection wire of the electrical component after being first wrapped across the bottom face, the winding post for receiving at least a portion of one wrap of the connection wire after it has been wrapped across the bottom face.
A self-leaded surface mount component holder comprising:
- a unitary housing formed of a plastic material for containing a particular electrical component,
- the housing including a substantially planar top wall portion and at least two sidewall portions depending downwardly from opposite edge regions of the top wall portion thereby defining a component cavity for receiving an electrical component therein,
- a plurality of winding bosses extending outwardly from each sidewall portion and including bottom faces lying in a bottom plane substantially parallel with a plane of the top wall portion,
- each winding boss also including an outer wall segment including an outer winding post portion projecting upwardly from the bottom face and an inner wall segment, interior faces of the outer wall segment and the inner wall segments converging in two directions thereby defining an interior groove, the groove for receiving and clinching a component connection wire of one of a plurality of predetermined different diameters.
A surface mount electrical assembly comprising self-leaded surface mount component holder including a unitary housing and an electric component therein, the holder being formed of a plastic material for containing a particular electrical component and having a substantially planar top wall portion, two sidewall portions depending downwardly from opposite edge regions of the top wall portion and extending outwardly of the top wall portion, two end wall portions joining outer edge regions of the sidewall portions thereby defining two top wall access/vent openings on either side of the top wall portion and a component cavity for receiving the electrical component therein,
- a plurality of winding bosses extending outwardly on opposite outer sides of the unitary housing and including bottom faces lying in a bottom plane substantially parallel with a plane of the top wall portion, each winding boss also including an outer wall segment including an outer winding post portion projecting upwardly from the bottom face and an inner wall segment, interior faces of the outer wall segment and the inner wall segments converging in two directions thereby defining an interior groove, the groove being sized to receive and clinch a component connection wire having one of a plurality of predetermined different diameters capable of being received within the groove, and
- the electrical component in the component cavity having plural component connection wires of one of the predetermined diameters, each component connection wire being first wrapped across the bottom face of a said winding boss, then being dressed through said groove and clinched by the converging interior faces of the outer wall segment and the inner wall segment and then being wound at least partially around the winding post portion.
