Referring now to FIGS. 1–3, a first or harness-side terminal of an electrical connection system, for attachment to a high power cable or wire harness 12, is illustrated. The harness has an insulative jacket 14 surrounding a conductor or conductors 16. The conductors 16 are exposed at an end 18 of the harness. A harness-side terminal 20 has a first, wire-connect section 22 including two sets of tabs. An outer set of tabs 24 is for crimping around the insulative jacket 14 of the cable or harness 12 to secure the terminal and harness together. An inner set of tabs 26 is for crimping around the exposed conductor 16 of the cable to make electrical contact between the wire and terminal. A relatively flat, straight second or stem section 28 of the terminal integrally extends from the wire-connect section. The stem section has two parallel, opposite sides 30 a and 30 b and makes an integral junction with a third, mating section 32.
A second terminal of the connection system designed for assembly with the harness-side or first terminal 20 is illustrated in FIGS. 4–6. The second terminal extends from a bus bar 62. The bus bar 62 has a main part 64 with branched arms 66 in the same plane. Multiple contact blades or prongs 68 are bent at right angles to ends of the arms. A straight, flat elongated part 70 also extends from the main part 64. The component-side or bus-side second terminal 72 is formed at an end of the part 70 distal from the bus bar 62. The terminal 72 is an integral part 74 of the bus bar and has a generally oval or semi-circular shape. The semi-circular part 74 has a centrally located short tube or annular collar 76 raised or protruding above a focal plane or upper surface of the part. The collar 76 has an outer diameter that is slightly smaller than a diameter of the aperture 34 in the first terminal 20.
In the assembly of the electrical connection system according to the present invention, illustrated in FIGS. 7–9, the first terminal 20 is positioned over the second terminal 72. The cut-out portions 38 and 40 are aligned with the overhanging plates 88 and 90, respectively, of the folded-over members. The planar ring 32 of the first terminal is lowered onto the semi-circular part 74 of the second terminal (FIG. 7). The central aperture 34 in the planar ring of the first terminal 20 receives the collar 76 on the second terminal, as depicted in FIG. 8. The underside of the mating section 32 of the harness-side terminal rests upon the upper surface of the part 74 of the bus-side terminal. A longitudinal axis of the harness-side terminal would be at about a forty-five degree angle relative to a longitudinal axis of the bus-side terminal. However, this configuration is for illustration purposes only and the folded-over members and cut-out portions could be arranged at different locations to change the initial alignment angle.
