Abstract
A latching connector having a pin, a housing, and a canted coil spring is disclosed. The housing has an opening that slidably receives the pin. The housing and the pin each have a groove that is sized and dimensioned to receive a portion of the canted coil spring. The pin groove and housing groove have a curved surface with a radius that is equal to or larger than the major axis of the canted coil spring. The canted coil spring has an outer diameter that is equal to or larger than the diameter of the housing groove. Together, the pin, housing, and canted coil spring provide a latching connector with a reliable and consistent connect force and disconnect force. The latching connector provides improved electrical conductivity from the pin to the housing by providing multiple contact points with the canted coil spring.
Claims8
A connector comprising:
- a pin having an insertion end and a pin groove disposed radially around the pin, wherein the pin groove has a first curved surface comprising a first constant radius of curvature;
- a housing having an opening sized and dimensioned to slidably receive the pin, and a housing groove disposed radially within the opening, wherein the housing groove has a second curved surface comprising a second constant radius of curvature that is substantially equal to the first radius of curvature of the first curved surface of the pin groove,
- wherein the housing groove comprises a first sidewall and a second sidewall extending from opposite ends of the second curved surface of the housing groove, and
- wherein the first sidewall and the second sidewall are parallel to each other and perpendicular to a longitudinal axis of the opening;
- and
- a canted coil spring having an outer diameter, a major axis, and a minor axis, wherein the outer diameter is equal to or greater than a diameter of the housing groove and wherein the major axis is sized and dimensioned to fit in the housing groove.
