Abstract
A conductive terminal for receiving a conductor is disclosed. The terminal includes a base and two resilient beams extending from the base. Generally distal the base, the beams define a mouth for receiving the conductor. The beams have facing inner edges which define a slot extending from the mouth. The beams define a generally egg-shaped aperture in an area extending between the slot and the base.
Claims15
A conductive terminal for receiving a conductor, said terminal comprising:
- a base;
- and
- a pair of resilient beams extending from said base, said beams defining a mouth at an end thereof for receiving the conductor and for providing a force normal to the conductor, said beams having facing inner edges defining a slot extending from said mouth toward said base and an egg-shaped aperture between said slot and said base and defined by said beams, said slot opening to said aperture and said egg-shaped aperture being structured and dimensioned to provide a predetermined stress distribution in the beams, said egg-shaped aperture being symmetrical about a central longitudinal axis of said terminal and being asymmetrical about an axis perpendicular to said central longitudinal axis, said central longitudinal axis dividing said egg-shaped aperture into two halves, each half of said egg-shaped aperture being defined by an arcuate edge along a corresponding one of said pair of beams, said arcuate edge being defined by a plurality of radii, wherein said radii defining said arcuate edge of each half of said egg-shaped aperture are symmetrical about said central longitudinal axis with respect to the radii defining said arcuate edge of the other half of said egg-shaped aperture, wherein a majority of said radii commence in said aperture and a minority of said radii commence outside said aperture.
An insulation displacement connector comprising:
- a base;
- a pair of alms extending upwardly from said base, each of said arms having an upper portion and a lower portion;
- a first central opening extending between said arms and being located between the upper portions thereof, said first opening being defined by parallel sides and being adapted to receive an insulated conductor, to remove a portion of the insulation from the conductor and to deform the conductor between said two arms;
- a second central opening located between the lower portions of said arms, said second opening being in communication with said first opening and having an upper portion with a first width dimension, a middle portion with a smaller second width dimension and a lower portion with a still smaller third width dimension;
- and
- said second opening being formed from three radii, a top radius in the upper portion, a middle radius in the middle portion and a bottom radius in the lower portion, and said second opening being defined by the following radii ratios:
- 0.05<top radius/middle radius<0.28, and
- 1.3<top radius/bottom radius<4.3, and
- 0.1<top radius/height<0.35 in which the height is the dimension of the second opening measured along its central longitudinal axis from an end of the first opening to the base.
