Patent ID: 7544895

Claim:
A wire duct tray comprising at least two successive segments extending one after another in a general longitudinal direction and each comprising longitudinal wires parallel to the longitudinal direction that are crossed by transverse wires extending across said longitudinal direction, the two successive segments presenting mutually adjacent ends interconnected by at least one sheet metal fishplate, the fishplate comprising, a core extending in the longitudinal direction between two lateral portions, said core presenting first and second edges parallel to said longitudinal direction; and two tabs extending respectively from said lateral portions of the core perpendicularly to the longitudinal direction, the two tabs being made integrally with the core; wherein the two tabs extend in the same direction from the first edge of the core up to a free end, said tabs being in alignment with one another in the longitudinal direction and each presenting a length of not less than 5 mm, and the tabs being shiftable from an uncrimped state in which the tabs cooperate with the base to form a U-shaped cross-section, and a crimped state, the core of the fishplate bearing against two end transverse wires belonging to each of the two successive segments, respectively, and each of the two tabs of the fishplate being shiftable to the crimped state in which the tabs are crimped respectively about a corresponding one of the two longitudinal wires that are mutually in line and that belong to the two duct tray segments, respectively, each of the tabs and the corresponding lateral portion of the core being wrapped around the corresponding longitudinal wire and in contact with more than 180° of the corresponding longitudinal wire when the tabs are shifted to the crimped state, and wherein the free end of each tab is at a first distance from said corresponding longitudinal wire and the second edge of the core is at a second distance from said corresponding longitudinal wire, said first and second distances being measured perpendicularly to said corresponding longitudinal wire, said first distance being greater than said second distance when each tab is in the uncrimped state.
