Abstract
There is provided a fastener able to prevent damage due to environmental factors such as ultraviolet rays, and impact from sanddust, lumps of ice, and raindrops without obstructing a flow of electric shock current that flows along a top surface of an outer skin. The fastener connects an outer skin of an aircraft to a structural member positioned inside this outer skin, and is provided with a dielectric layer arranged to cover one end surface of a head section, and a conductive layer arranged to cover one end surface of this dielectric layer.
Claims10
A fastener for connecting an outer skin of an aircraft to a structural member positioned inside the outer skin, comprising:
- a head section;
- a dielectric layer arranged such that a first end surface of the dielectric layer covers an end surface of said head section, said end surface of said head section and said first end surface of said dielectric layer having a substantially same shape;
- a conductive layer arranged to cover a second end surface of said dielectric layer;
- and
- wherein an outer diameter of said dielectric layer is substantially equal to an outer diameter of said end surface of said head section.
An aircraft assembly part comprising:
- an outer skin constructed with a conductive plastic material as a main component;
- a structural member that supports said outer skin from an inside thereof;
- and
- a fastener that connects said outer skin to said structural member, wherein said fastener comprises
- a head section
- a dielectric layer arranged such that a first end surface of the dielectric layer covers an end surface of said head section, said end surface of said head section and said first end surface of said dielectric layer having a substantially same shape;
- a conductive layer arranged to cover a second end surface of said dielectric layer;
- and
- wherein an outer diameter of said dielectric layer is substantially equal to an outer diameter of said end surface of said head section.
An aircraft assembly part comprising:
- an outer skin constructed with a conductive plastic material as a main component;
- a structural member that supports said outer skin from an inside thereof;
- and
- a fastener that connects said outer skin to said structural member, wherein said fastener comprises,
- a head section;
- a dielectric layer arranged such that a first end surface of the dielectric layer covers an end surface of said head section, said end surface of said head section and said first end surface of said dielectric layer having a substantially same shape;
- a conductive layer arranged to cover a second end surface of said dielectric layer;
- wherein said dielectric layer has a disc shape, and an outer diameter of said conductive layer is greater than an outer diameter of said end surface of said head section;
- and
- wherein an outer diameter of said dielectric layer is substantially equal to the outer diameter of said end surface of said head section,
- and wherein a back surface of a circumferential portion of said conductive layer is in contact with a surface of said outer skin.
