DETAILED DESCRIPTION

[0026] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0027] A bundled wire connector in accordance with a non-limiting example, is indicated generally at 10 in FIG. 1. Bundled wire electrical connector 10 includes a connector 14 that supports a plurality of electrical conductors 16. In a non-limiting example, each of the plurality of electrical conductors 16 includes an outer insulating layer or insulation portion 19 that envelops an electrically conductive portion 21 (FIG. 3). In a non-limiting example, electrically conductive portion 21 may take the form of copper wire (not separately labeled). However, it should be understood that electrically conductive portion 21 may take on a variety of forms. In a non-limiting example, electrically conductive portion 21 of each of the plurality of electrical conductors 16 includes a terminal end, such as shown at 23, that are joined by an electrically conductive material 28.

[0028] In a non-limiting example shown in FIG. 2, connector 14 includes a first axial end 38 and a second axial end 40. Second axial end 40 is opposite to first axial end 38 which defines an axial outer surface 42. An outer surface 44 extends between first axial and 38 and second axial end 40. An inner surface 46 extends between first axial end 38 and second axial end 40 radially inwardly of outer surface 44. Inner surface 46 defines a passage 50. In a non-limiting example, plurality of electrical conductors 16 are placed in passage 50 such that the insulation portion 19 extends within passage 50.

[0029] In a non-limiting example, the insulation portion 19 of outer ones of the plurality o conductors is in contact with inner surface 46 and terminal ends 23 of the electrically conductive portion 21 may project axially outwardly of axial outer surface 42 as shown in FIG. 3. At this point, connector 14 may be swaged or crimped with insulating portion 19 of the outer ones of the plurality of conductors 16 remaining in passage 50 in contact with inner surface 46.

[0030] Terminal ends 23 of each of the plurality of electrical conductors 16 may be trimmed to be substantially co-planar with first axial end 38 as shown in FIG. 4. In a non-limiting example, after being trimmed, each terminal end 23 of each of the plurality of electrical conductors 16 is exposed. Electrically conductive material 28 may now be deposited onto each of the terminal ends 23 of each of the plurality of electrical conductors 16 as shown in FIG. 1. The deposition of electrically conductive material 28 onto terminal ends 23 electrically connects each of the plurality of electrical conductors 16. The electrically conductive material 28 may also be deposited onto axial outer surface 42. By avoiding the removal of insulating portion 19 and only connecting terminal ends 23, a bundle of electrical conductors 16 may be joined without the need for costly mechanical devices or the use of harsh chemicals to needed to perform a wire stripping operation.

[0031] In a non-limiting example, electrically conductive material 28 may be deposited through a variety of techniques including dipping, soldering, plating and the like. In addition, electrically conductive material 28 may be additively applied to axial outer surface 42 and terminal ends 23. Electrically conductive material 28 may be additively applied to have a substantially constant cross-section such as shown in FIG. 1, or may be applied to form an electrical connector element 60 that projects axially outwardly of first axial end 38 such as shown at FIGS. 5 and 6. In one non-limiting example, electrical connector element 60 may be added in layers to form a pin connector 62 (FIG. 5). In another non-limiting example, electrical connector element 60 may be added in layers to form a socket connector 70 (FIG. 6). In a non-limiting example, socket connector 70 may include an inner wall or bore 72 that defines an internal passage 74. In a non-limiting example, a plurality of threads 78 may be formed on inner wall 72.
