THIN SECTION INTERLOCK GEOMETRY FOR MOLDING PLASTIC

To address the issue of securely joining thin sections of magnesium housing, a computing device with a housing, a metal strip, and a plastic interlock structure is provided. The housing may include adjacently arranged first and second metal sections separated by a void. The metal strip may have a hole with an undercut region formed therein, and it may be joined to a surface of one of the metal sections. The plastic interlock structure may be positioned at least partially in the void, and the metal strip may be embedded in the plastic interlock structure to strengthen the joint between the metal sections of the housing. The plastic interlock structure may physically and electrically isolate adjacent metal sections from one another to form an antenna that permits transmission of radio waves.
