Abstract:
1. A female electrical contact, comprising: 1) at least one pair of elongated blades comprising opposing planar members having opposing faces pivotally connected, the blades having a gap there between into which a male prong can be inserted to make electrical contact with the blades, and further, the blades having at least one extension with a wiping surface; and, 2) a shaped member having at least one fixed wiping surface to engage the wiping surface of the at least one extension at least one predetermined angle; and, 3) a resilient member including a deflectable section and a fixed section in communication with the deflectable section, one section being mechanically referenced to the blades, and the other section being mechanically fixed relative to the shaped member; and further, the resilient member being configured to urge the extensions into increasing contact with the shaped member resulting in increased side pressure on the male prong being inserted into the contact; whereby upon insertion of the male prong into the gap between the blades, the female electrical contact suddenly accepts the male prong when full insertion pressure is reached, and then, upon application of substantially a predetermined extraction force to the male prong, the female electrical contact abruptly releases the male prong.
