Abstract: The present invention proposes a cap having a collar portion with three or more contact regions arranged to contact the end of a fastener around which the collar portion is provided, the collar portion having a lobed shape in cross-section such that an outwardly projecting lobe extends between each neighbouring pair of contact regions. An advantage of this lobed arrangement is that the cap can tolerate relatively large manufacturing tolerances at the fastener end. For example, the cap may be for fitting over a nut or fastener head, with the contact regions of the cap being arranged to contact corresponding contact regions on a cylindrical collar base portion of the nut or fastener head. The diameter of this cylindrical collar portion may not be well controlled, so that the manufacturing tolerance is high. The lobed shape of the cap base ensures that the contact regions will always provide a good frictional engagement with the nut, whether the cylindrical collar is undersized, oversized, or at its nominal diameter.
Abstract translation: 本发明提出一种具有凸缘部分的盖子，其具有三个或更多个接触区域，该接触区域布置成接触紧固件的端部，所述紧固件的所述套环部分围绕该端部设置，所述凸缘部分的横截面具有凸起形状，使得向外突出的凸角延伸 在每个相邻的接触区域对之间。 这种裂纹布置的一个优点是盖可以容忍紧固件端部的相对较大的制造公差。 例如，盖可以用于装配在螺母或紧固件头部上，其中盖的接触区域布置成接触螺母或紧固件头部的圆柱形套筒底座部分上的对应的接触区域。 该圆柱形套环部分的直径可能不能很好地控制，因此制造公差很高。 帽基部的裂片形状确保接触区域始终与螺母始终提供良好的摩擦接合，无论圆柱形套环是否尺寸过小，尺寸过大或其公称直径。

Abstract: The present invention proposes a cap for forming a sealed cavity around one end of a fastener to thereby contain out-gassing and sparking events in the event of a lightning strike to the fastener. The invention also proposes a joint comprising such a cap, and a kit of parts and method for installing such a cap. A cap according to the invention comprises: an inner cap member having an annular base terminating at an edge which surrounds an opening into an air cavity for enclosing the one end of a fastener; and an outer cap member having an annular skirt or flange which extends radially outwardly away from the annular base, the annular skirt or flange and annular base between them defining an annular sealing cavity. The cap also comprises a sealing material inlet comprising an opening in the outer cap member that is in fluid communication with the annular sealing cavity, the opening being arranged to interconnect with a sealing material injection device to provide a flow of curable sealing material from the sealing material inlet into the annular sealing cavity. The inner cap member and outer cap member are welded together.

Abstract: A cap for forming a sealed cavity around an end of a fastener is disclosed. The cap has a cap body with an annular base terminating at a base rim which surrounds an opening into a central cavity. The cap also has an annular skirt providing an annular pocket between the skirt and the base. An inlet hole is provided in the skirt which is in fluid communication with the annular pocket. A protuberance protrudes in the annular pocket and faces the inlet hole to promote a flow of sealant injected through the inlet hole to flow annularly around the annular pocket.

Abstract: A joint having a structure and a fastener passing through the structure. A cap has a body portion with an annular base terminating at an edge, the body portion forming an enclosure around an end of the fastener. The cap also has an annular flange which extends outwardly from the body portion and is set back from the edge of the base so as to define a pocket between the flange and the base. A sealant is provided in the pocket between the flange and the base, the sealant bonding the cap to the structure via a sealant/cap interface with the cap and a sealant/structure interface with the structure. The surface area of the sealant/cap interface is greater than the surface area of the sealant/structure interface.
