Abstract

An electrical cable assembly is presented herein. The electrical cable assembly includes a multiconductor flat cable including a first and second electrically conductive wire arranged in a coplanar fashion with each other and encased within a planar dielectric structure. A slot is defined in the planar dielectric structure intermediate the first and second wires, thereby forming first wing features in the dielectric structure extending from the first wire and second wing features extending from the second wire. Exposed portions of the first and second wires extend beyond the first and second wing features. A method of forming the electrical cable assembly, an apparatus for forming the electrical cable assembly, and an electrical terminal configured for use in the electrical cable assembly is also presented. The wing features may include holes and the terminals may include prongs to be received in the holes.

First claim

We claim:

1. An electrical cable assembly, comprising:
a multiconductor flat cable including a first and second electrically conductive wire encased within a planar dielectric structure, wherein a slot is defined in the planar dielectric structure intermediate the first and second wires, thereby forming first wing features in the dielectric structure extending from the first wire and second wing features extending from the second wire and wherein exposed portions of the first and second wires extend beyond the first and second wing features; and
first and second electrical terminals, wherein the exposed portion of the first wire is attached to the first terminal and the exposed portion of the second wire is attached to the second terminal, wherein the first and second terminals define prongs that are received within holes defined in portions of the first and second wing features.

2. The electrical cable assembly according to claim 1 , further comprising:
a connector comprising a housing formed of a dielectric material; wherein the first and second electrical terminals are disposed within the housing.

3. The electrical cable assembly according to claim 1 , wherein the prongs retain the first and seconds wires to the first and second terminals.

4. The electrical cable assembly according to claim 1 , wherein the prongs are a pair of triangular prongs.

5. The electrical cable assembly according to claim 4 , wherein the pair of triangular prongs is a pair of right triangular prongs and wherein a first prong in the pair of right triangular prongs is arranged in reverse of a second prong in the pair of right triangular prongs.

6. The electrical cable assembly according to claim 2 , wherein the second wire is shorter than the first wire, wherein the first wire is bent such that it crosses over the second wire, and wherein the first terminal is laterally offset from the first wire within the connector.

7. The electrical cable assembly according to claim 2 , further comprising:
a cover formed of dielectric material attached to the housing, thereby enclosing the first and second terminals.

8. The electrical cable assembly according to claim 2 , wherein the first and second terminals each define a groove configured to receive the first and second wires and are sized to provide a friction fit between the first and second terminals and the first and second wires.

9. The electrical cable assembly according to claim 2 , wherein the first and second wires are attached to the first and second terminals using a welding process.

10. The electrical cable assembly, comprising:
a multiconductor flat cable including a first and second electrically conductive wire encased within a planar dielectric structure, wherein a slot is defined in the planar dielectric structure intermediate the first and second wires, thereby forming first wing features in the dielectric structure extending from the first wire and second wing features extending from the second wire and wherein exposed portions of the first and second wires extend beyond the first and second wing features;
a connector comprising a housing formed of a dielectric material; and
an electrical terminal disposed within the housing, wherein the first wire is bent such that the exposed first wire is aligned with the second exposed wire; wherein the exposed portion of the second wire is attached to the electrical terminal, and wherein the exposed portion of the first wire is attached to the exposed second wire, thereby attaching the exposed first wire to the electrical terminal.

11. The electrical cable assembly according to claim 10 , wherein the electrical terminal defines prongs, wherein a portion of the second wing features is attached to the electrical terminal by inserting the prongs within holes defines in portions of the second wing features, thereby retaining the second wire to the electrical terminal, and wherein the portion of the first wing features is attached to the electrical terminal by inserting the prongs within the holes defined in portions of the first wing features, thereby retaining the first wire to the electrical terminal.

12. The electrical cable assembly according to claim 1 , wherein the first and second wires have a substantially round cross section and wherein the first wire has a different cross-sectional area than the second wire.
