Electrically conductive bushing connection to structure for current path

摘要

An electrically conductive structural connection employs a pass through or fastener having a first diameter. A fastener hole, with a second diameter larger than the diameter of the pass through, extends through a thickness of a structure and receives the pass through. A bushing having a diameter and a thickness to fit between the first and second diameters extends though and past the thickness of said structure. When the feedthrough is compressively secured to the structure, the bushing expands radially between the first diameter and the second diameter to maintain at least one contact point between the fastener and the structure.

1. An electrically conductive structural connection, comprising:
a fastener having a first diameter; a carbon fiber resin composite structure having a fastener hole with a second diameter larger than the first diameter extending through a thickness of the structure and receiving the fastener; an electrically conductive bushing extending through and past the thickness of said structure between said first and second diameters in an uncompressed condition and wherein when said fastener is compressively secured to said structure, the bushing is elastically deformed to said thickness and between said first diameter and said second diameter to maintain at least one contact point between the fastener and the structure to conduct electrical current.
