Abstract

An insulation displacement connection contact has a base plate extending along a longitudinal axis and having a mating end and an opposite terminating end. The base plate has a contacting portion positioned proximate to the mating end, a plate-like wire supporting portion integrally extending outward from the base plate at the terminating end, and an insulation displacement connection member positioned between the contacting portion and the wire supporting portion, proximate to the terminating end.

First claim

What is claimed is:

1. An insulation displacement connection contact comprising:
a base plate extending along a longitudinal axis and having a mating end and an opposite terminating end, the base plate having
a contacting portion positioned proximate to the mating end,
a plate-like wire supporting portion integrally extending from the terminating end perpendicularly to the longitudinal axis of the base plate, and
an insulation displacement connection member positioned proximate to the terminating end between the contacting portion and the wire supporting portion, the insulation displacement connection member including a first plate having a cutting slit, the first plate extending from the base plate parallel to the wire supporting portion.

2. The insulation displacement connection contact of claim 1 , wherein a height of the wire supporting portion is lower than a height of the insulation displacement connection member.

3. The insulation displacement connection contact of claim 1 , wherein the wire supporting portion has a wire receiving notch positioned on an outermost end from the base plate.

4. The insulation displacement connection contact of claim 3 , wherein the first plate is positioned proximate to the mating end of the base plate, and the insulation displacement connection member further includes
a second plate positioned proximate to the terminating end of the base plate.

5. The insulation displacement connection contact of claim 4 , wherein the first plate and the second plate are separated by a distance along the longitudinal axis and face each other.

6. The insulation displacement connection contact of claim 5 , wherein the second plate has a cutting slit, the cutting slit on each of the first plate and the second plate extending along a central region perpendicular to the longitudinal axis.

7. The insulation displacement connection contact of claim 6 , wherein each cutting slit has:
a pair of opposing insulation cutting edges positioned a first distance apart on an outer end; and
a pair of opposing conductor contacting edges positioned a second distance apart on a lower end.

8. The insulation displacement connection contact of claim 7 , wherein the first distance is greater than the second distance.

9. The insulation displacement connection contact of claim 8 , wherein the insulation displacement connection member further includes a coupling portion connecting the outer ends of the first plate and the second plate.

10. The insulation displacement connection contact of claim 9 , wherein the insulation cutting edges of the first plate and the insulation cutting edges of the second plate are in communication with each other through a notch cut longitudinally through the coupling portion.

11. The insulation displacement connection contact of claim 1 , wherein the contacting portion includes:
a first base plate;
a first sidewall bent upward from an edge of the first base plate; and
a top plate bent from an upper edge of the first sidewall to extend substantially parallel with the first base plate.

12. The insulation displacement connection contact of claim 11 , wherein the contacting portion is substantially C-shaped.

13. The insulation displacement connection contact of claim 12 , wherein a resilient contacting member is positioned on a mating end side of the top plate.

14. The insulation displacement connection contact of claim 13 , wherein the resilient contacting member extends firstly towards a terminating end side of the first base plate before bending to extend towards a mating end side of the first base plate.

15. An electrical connector comprising:
a housing having a plurality of contact receiving passageways; and
a plurality of insulation displacement connection contacts positioned in the contact receiving passageways, each insulation displacement connection contact having
a base plate extending along a longitudinal axis and having a mating end and an opposite terminating end, the base plate having
a contacting portion positioned proximate to the mating end,
a plate-like wire supporting portion integrally extending from the terminating end perpendicularly to the longitudinal axis of the base plate, and
an insulation displacement connection member positioned proximate to the terminating end between the contacting portion and the wire supporting portion, the insulation displacement connection member including a first plate having a cutting slit, the first plate extending from the base plate parallel to the wire supporting portion.

16. The electrical connector of claim 15 , wherein each of the contact receiving passageways extend longitudinally through the housing, each having:
a contact portion receiving space on the mating end; and
an insulation displacement connection member receiving space on the terminating end.

17. The electrical connector of claim 16 , wherein each contact receiving passageway is separated by opposing partition walls.

18. The electrical connector of claim 17 , wherein a pair of wire movement restricting portions are positioned on the opposing partition walls on both sides of each insulation displacement connection member receiving space.

19. The electrical connector of claim 18 , wherein the pair of wire movement restricting portions are positioned above the wire supporting portion of the base plate.
