Patent ID: 7195418

Claim:
A joining assembly, comprising: a junction element including: a first longitudinal partition wall fastened to a metallic panel, the metallic panel integral with a stiffener and comprising a vertical core and at least one baseplate, a second longitudinal partition wall fastened to a composite panel, and a lower branch coupled to a proximal portion of an extension of each of the first and second longitudinal partition walls; a first fitting element including a first strain relief body fitting fastened to the stiffener and having a first heel; and a second fitting element including a second strain relief body fitting on the composite panel and having a second heel, wherein the first and second heels of the first and second fitting elements, respectively, are fastened to opposing sides of the lower branch of the junction element, wherein a lower rib is disposed directly adjacent the lower branch and interposed between one of the first and second heels and the lower branch, and wherein the lower rib, the lower branch, and the first and second heels are fastened together by a fastener that passes through the lower rib, the lower branch, and the first and second heels, thereby reducing compression stress on the junction element.
