For clarity, previously identified features retain their reference numbers in subsequent drawings.
In a particular embodiment of the invention, the through-holes 11 are of a much smaller bore size (circular or rectangular) than the cross-sectional area of the intended stator leads 3 which are to be inserted therethrough. For example, one or more of the bore sizes of the through-holes 11 is less than 90% of the cross-sectional area or diameter of the stator leads 3, or more particularly, less than 75% of the cross-sectional area or diameter of the stator leads 3, or even more particularly, less than 50% of the cross-sectional area or diameter of the stator leads 3. The elastic properties of the stator lead retainer body 1 allows the insertion, and facilitates securing of a larger cross-section/diameter stator lead 3 within a smaller bore size through-hole 11.
Further particularly, the through-holes 11 may have any particular cross-sectional bore shape, e.g., be of a circular, elliptical, square, or rectangular cross-section shape, which may be the same or different from the cross-sectional shape of the stator lead which is to be inserted within the through-hole 11. The elastic properties of the stator lead retainer 1 allows the insertion, and facilitates securing of a larger and/or differently shaped cross-section/diameter stator lead 3 within the through-hole 11. In this manner, the elastic properties also permit a wide range and cross-sectional shapes of stator leads to be used with the stator lead retainer body 1. As an example, the bore shape of the through-holes 11 may be circular (e.g., circular or elliptical), and the cross-sectional shape of the stator leads 3 may be non-circular (e.g., square or rectangular-shaped).
In an exemplary embodiment, the stator leads 3 is constructed from copper material and the through-holes 11 are circularly-shaped and sized to be 75% less than the cross-sectional area of the rectangular stator leads 3 which are to be inserted therethough. Those skilled in the art will appreciate that other materials, as well as other bore sizes and cross-sections of the through-holes 11 may be implemented in alternative embodiments of the present invention.
Further exemplary, the stator lead retainer body 1 further includes a flanged end 12 and a beveled end 15; both, in a particular embodiment, integrally constructed with the stator retainer body 1 from the aforementioned elastic materials. In a particular embodiment, the flanged end 12 is constructed from the aforementioned elastic material, such that it can be compressibly secured between a generator casing and a rectifier casing, as will be further illustrated below. In such an embodiment, the elastic properties of the flanged end advantageously provides a shock absorbing interface between the generator and rectifier casings to minimize wear and tear on each unit.
In a particular embodiment, the stator lead retainer body 1 is formed from a material having a modulus of elasticity in the range of 0.0007 to 0.004 Gpa. For example, the stator retainer body 1 may be constructed from polysiloxane. In other embodiments, operation 510 includes constructing the stator lead retainer body 1 to have a flanged end, or alternatively, a beveled end.
In a particular embodiment of operation 512, the cross-section of at least one of the plurality of through-holes 11 is formed in a different shape/geometry as compared with the cross-section of a stator wire 3 which is to be inserted therein. For example, one or more of the through-holes 11 may be formed of a circular (or elliptical) cross-sectional shape, and a stator wire 3 which is to be inserted therein may be of a rectangular (or square) cross-sectional shape, or visa versa. Of course, other cross-sectional shapes such as triangular, pentagon, octagon, etc. may be used as well for either of the through-hole cross-sectional shapes or the stator wire cross-sectional shapes. More generally, operation 512 may include the formation of one or more through-holes 11 having a cross-sectional shape which is different from the cross-sectional shape of a stator wire 3 which is to be inserted therein.
Alternatively, or in addition to a mis-match in the cross-sectional shapes of at least one of the through-holes 11 and a stator wire 3 which is to be inserted therein, the bore size of at least one of the plurality of through-holes 11 may also be mismatched to the bore size of a stator wire 3 which is to be inserted therein. In a particular embodiment of operation 512, one or more of the through holes 11 is formed having a bore size which is 90% or less of the cross-sectional area of a stator wire 3 which is to be inserted therein. In another embodiment of operation 512, one or more of the through-holes 11 is formed having a bore size which is 75% or less, or even more preferably, 50% or less than the cross-sectional area of of a stator wire 3 which is to be inserted therein.
