Patent attributes
A conductive contact includes a variable-diameter spring and a post. The variable-diameter spring includes a spiral body having a plurality of rotations, a first end, and a second end configured for securing with the spiral body. The first end and the second end are arranged at two opposite ends of the spiral body. An axis is defined across the first end and the second end, radial intervals are defined between every two adjacent rotations measured substantially perpendicularly to the axis. The post is secured to the first end and configured for detachably and conductively contacting with a conductive pad. Every two adjacent rotations are kept away from each other in response to compression along the axis direction of the spiral body applied on the post.
