Abstract
Abstract A bifurcated electrical contact having a pair of resiliently deflectable arms having end portions adapted to contact each other. The restorative force of the deflected arms is increased by projections (17) spaced from the end portions (16), which contact each other before the surfaces (19) of the end portions contact each other thereby increasing the restorative force on the arms.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
268 words
An electrical contact formed from sheet metal into a single unitary structure, said contact comprising: a shaft having a central axis, a forward end, a rear end; a first elongated member integrally connected to said shaft and extending transverse to the central axis of said shaft; and a pair of resiliently deflectable arms arranged in spaced relationship about said central axis, said arms including: a first elongated portion having one end integrally connected to said first elongated member, said first elongated portion extending in a direction away from said shaft and first member and parallel to the central axis of said shaft; a second elongated portion having one end integrally connected to the other end of said first elongated portion, said second elongated portion extending in a direction away from said first member and at an angle to the central axis of said shaft; a third elongated portion having one end integrally connected to the other end of said second elongated portion, said third elongated portion extending in a direction away from said shaft and first member and parallel to the central axis of said shaft; and a fourth elongated portion having one end integrally connected to the other end of said third elongated portion, said fourth elongated portion extending in a direction transverse to the central axis of said shaft, the fourth elongated portion of each arm arranged so that the other ends of each fourth elongated portion face each other; and a first projection located at the junction between the first and second elongated portions of one of said arms and extending towards said other arm.
Claim 2
Dependent Claim
268 words
An electrical contact formed from sheet metal into a single unitary structure, said contact comprising: a shaft having a central axis, a forward end, a rear end; a first elongated member integrally connected to said shaft and extending transverse to the central axis of said shaft; and a pair of resiliently deflectable arms arranged in spaced relationship about said central axis, said arms including: a first elongated portion having one end integrally connected to said first elongated member, said first elongated portion extending in a direction away from said shaft and first member and parallel to the central axis of said shaft; a second elongated portion having one end integrally connected to the other end of said first elongated portion, said second elongated portion extending in a direction away from said first member and at an angle to the central axis of said shaft; a third elongated portion having one end integrally connected to the other end of said second elongated portion, said third elongated portion extending in a direction away from said shaft and first member and parallel to the central axis of said shaft; and a fourth elongated portion having one end integrally connected to the other end of said third elongated portion, said fourth elongated portion extending in a direction transverse to the central axis of said shaft, the fourth elongated portion of each arm arranged so that the other ends of each fourth elongated portion face each other; and a first projection located at the junction between the first and second elongated portions of one of said arms and extending towards said other arm.
Claim 3
Dependent Claim
39 words
The electrical contact as recited in claim 1 including: a second projection on said other arm, said second projection located at the junction between the first and second elongated portions of said other arm and facing said first projection.
Claim 4
Dependent Claim
48 words
An electrical contact as recited in claim 2 wherein said projections are spaced apart from each other a distance B and said other ends of said fourth elongated portions are spaced apart from each other a distance A and wherein the distance A is greater than distance B.
Claim 5
Dependent Claim
24 words
The electrical contact as recited in claim 3 wherein a cross-section taken transverse to the longitudinal axis of said elongated portions is generally square-shaped.
