Torsionally-induced contact-force conductors for electrical connector systems
View Patent ↗An electrical connector. An electrical connector comprising a connector body having a first channel and a first conductive element extending through the first channel in a first tip section. The first tip section having a first moment arm that, when forced in contact with a first conductive surface, twists the first conductive element to produce a torsion force. The torsion force holds the first tip section in contact with the first conductive surface.
1. An electrical connector comprising:
a rigid torsion bar conductor with
i) a linear central section aligned on a longitudinal axis, the linear central section extending between a first bend and a second bend;
ii) a first moment arm aligned on a first axis and extending outward from the linear central section at the first bend; and
iii) a second moment arm aligned on a second axis and extending outward from the linear central section at the second bend; and
a first contact forcibly engaged with the first moment arm and exerting a first force that is transmitted through the first moment arm and twists the linear central section in a first direction circumferential to the central axis; and,
a second contact forcibly engaged with the second moment arm and exerting a second force that is transmitted through the second moment arm, twisting the linear central section circumferential to the central axis and in a direction opposite the first direction;
the rigid torsion bar conductor and the first and the second contacts arranged such that the rigid torsion bar conductor is free to rotate about the longitudinal axis in response to said first and said second forces.
2. The electrical connector of claim 1 , wherein the rigid torsion bar conductor consists essentially of a bent metal rod.
3. The electrical connector of claim 2 , wherein at least a portion of the bent metal rod is comprises a cylindrical shape.
4. The electrical connector of claim 1 , further comprising a connector body configured to align the longitudinal axis of the linear central section along the longitudinal a predetermined axis.
5. The electrical connector of claim 1 wherein the linear central section is symmetrically formed around the longitudinal axis.
6. The electrical connector of claim 1 wherein a mid-point defines a point on the linear central section half way between the first and second bends, and wherein the linear central section extends symmetrically from the mid point outward, along the longitudinal axis.
7. The electrical connector of claim 1 wherein the first and second moment arms are approximately parallel to each other; and further wherein the first and second contacts are arranged such that said first and said second forces have directions approximately perpendicular to each other.
