Abstract
A flex cable has a number of conductive wirings for electrically coupling electrical leads of an electrical component to a wiring board. The flex cable has a conductive tab for electrically coupling one of the conductive wirings to one of the leads. The flex cable is bendable to form an essentially horizontal portion and an essentially vertical portion. The conductive tab is disposed at a transition between the horizontal portion and the vertical portion.
Claims16
A flex cable, comprising:
- a conductive wiring, bent to form an angled shape, defining first and second substantially perpendicular regions with a bend region therebetween;
- and
- a conductive tab electrically coupled to said conductive wiring extending from the bend region coplanar with the first region;
- and,
- a through opening in the second region providing access to the conductive tab.
An electro-optical device comprising:
- an optical sub-assembly for converting optical signals into electrical signals or for converting electrical signals into optical signals, the optical sub-assembly including electrical leads extending from a rear end thereof;
- a wiring board including electronic circuitry for operating the optical sub-assembly;
- and
- a flex cable comprising:
- a first region extending parallel to the rear end of the optical sub-assembly above an upper surface of the wiring board;
- a second region extending parallel to the upper surface of the wiring board and perpendicular to the first region;
- a bend region between the first and second regions;
- a tab coplanar with the first region extending outwardly from proximate the bend region for electrical connection with one of the leads from the optical sub-assembly that extends below the upper surface of the wiring board;
- and
- a through opening proximate the bend region for accessing the electrical lead electrically connected by the tab;
- wherein conductive wiring extends from the first region to the second regions for electrically connecting at least one of the electrical leads from the optical sub-assembly to the wiring board;
- and
- wherein conductive wiring extends from the tab to the second region for electrically connecting one of the electrical leads from the optical sub-assembly to the wiring board.
An electro-optical device comprising:
- an optical sub-assembly for converting optical signals into electrical signals or for converting electrical signals into optical signals, the optical sub-assembly including electrical leads extending from a rear end thereof;

- and
- a flex cable, comprising:
- a conductive wiring, bent to form an angled shape, defining a first region extending parallel to the rear end of the optical sub-assembly, a second region substantially perpendicular to the first region extending parallel to an upper surface of the wiring board, and a bend region therebetween;
- a conductive tab electrically coupled to said conductive wiring coplanar with the first region, extending from the bend region into electrical contact with one of the optical sub-assembly leads;
- and,
- a through opening in the second region providing access to the conductive tab and the contacted lead.
