Claims
- 1. An electrical connector for interconnecting electrical signals, the connector comprising:
- a housing having terminal receiving cavities therein; and
- a plurality of terminals, disposed in said cavities, having an insulation displacement portion comprising plate means having a contiguous radiused portion, said plate means including a slot profiled to terminate a conductor of an insulated wire and finger portions separated from said radiused portion thereby defining free ends which lie substantially in the plane of said plate means, adjacent to the radiused portion and flanking the conductor receiving slot, the finger portions having edges aligned with, and colinear with, edges of the conductor receiving slot, whereby the finger portions effectively increase the slot length without increasing the height of said terminal.
- 2. The connector of claim 1 wherein the electrical terminals further comprise a normal force contact portion.
- 3. The connector of claim 2 wherein the normal force contact portion comprises two elongate arms radially twisted about an axial center line of said arms to dispose surfaces of the same plane in opposed relationship with one another.
- 4. The connector of claim 1 wherein the plate means comprise first and second substantially parallel plates having a bight portion therebetween.
- 5. The connector of claim 4 wherein the bight portion comprises an opening stamped therein profiled for receiving laterally thereof an insulated wire.
- 6. The connector of claim 5 wherein the opening in said bight portion defines two strap portion connected to said parallel plates.
- 7. The connector of claim 5 wherein the wire receiving opening is continuous with the conductor receiving slots.
- 8. The connector of claim 1 wherein the finger portions are beveled inwardly to progressively receive insulation of a wire.
- 9. The connector of claim 1 wherein the finger portions comprise means for severing insulation of a wire to be terminated.
- 10. The connector of claim 9 wherein the severing means comprises pointed sections on said finger portions.
- 11. The connector of claim 1 further comprising a relief area disposed between said finger portions and said radiused portion for receiving insulation of an insulated wire.
- 12. The connector of claim 4 wherein a first longitudinal portion extends from said first plate, and a second longitudinal portion extends from said second plate and the conductor receiving slots extend downwardly through the plate portions and partially into the longitudinal sections.
- 13. The connector of claim 12 wherein the second longitudinal portion connects the insulation displacement portion with a normal force contact portion.
- 14. The connector of claim 12 further comprising tang portions extending from said first longitudinal portion profiled to wrap around a wire for strain relief.
- 15. The connector of claim 1 wherein the housing cavities include a base and sidewalls upstanding thereof, and a top wall at least partially enclosing said cavity.
- 16. The connector of claim 15 wherein the terminals are profiled to fit within the housing cavities, the width of the terminals profiled to fit between the sidewalls and the insulation displacement portions profiled to fit below the top wall.
- 17. The connector of claim 16 wherein the top wall is profiled to expose the opening in said bight portion allowing mass termination of the wires to the insulation displacement portion while the terminals are fully inserted within the housing.
- 18. An electrical connector for interconnection to an array of pins, the connector comprising:
- a housing having terminal receiving cavities therein, the cavities including a base and sidewalls upstanding thereof and a top wall at least partially enclosing said cavity; and
- a plurality of terminals disposed in said cavity, the terminals being stamped and formed to define a first flat portion lying adjacent to the base, then extending upwardly to define a first flat plate, and extending downwardly to define a second flat plate with a bight portion between said flat plates, the flat plates and the bight portion being continuous through radiused portions, the bight portion having an opening stamped to extend longitudinally of said terminal and profiled to receive laterally thereof an insulated wire, the opening in said bight portion defining two strap portions interconnecting said plates, the first and second plates having slots contiguous with said wire receiving opening extending downwardly towards said base, the slots in said plates profiled to terminate a conductor of said insulated wire, the plates including finger portions separated from said strap portions to define free ends, the finger portions lying closely adjacent to the radiused portions and flanking the conductor receiving slots, the finger portions having edges colinear with edges of the slots, a second flat portion extending from said second flat plate lying adjacent to said base, two arms extending from said second flat portion formed upwards orthogonally to the base then flattened to lie substantially parallel to said base, the arms then twisted to dispose surfaces initially in the same plane into parallel and opposed relationship with one another.
