A connector for connecting together rigid structures. The connector includes a stack of coupling contacts pivotably disposed within a housing. Each coupling contact is generally H-shaped and defines opposing first and second spaces. The first and second spaces are aligned to form first and second receiving grooves in the stack, respectively. The connector may also include one or more mounting contacts partially disposed within the housing. Each mounting contact has one or more fastening structures joined to a bar section. The fastening structures are adapted for securement to the substrate and the bar section is disposed in the second receiving groove of the stack of coupling contacts.
