Abstract
An electrical contact assembly including a housing defining a bore having an internal groove formed therein; an axial canted coil spring having a plurality of spring coils, each spring coil having a spring coil length, the plurality of spring coils disposed in the internal groove with a groove width having a width dimension; wherein at least one spring coil comprises a minor axis length that is greater than the width dimension. An insertion object sized for insertion into the bore of the housing; wherein a clamping force of the axial canted coil spring retains the insertion object within the bore; and wherein the axial canted coil spring provides an electrical conductive path between the insertion object and the housing that is less than 50% of the spring coil length.
