Systems for establishing electrical interconnections for helmet-mounted devices

Systems (100) for establishing electrical interconnections for helmet- mounted devices are disclosed. A system for establishing an electrical interconnection for a helmet-mounted device is comprises a first interconnect mechanism (110) coupled to one of a helmet and the helmet-mounted device, and a second interconnect mechanism (160) coupled to the other one of the helmet and the helmet-mounted device. The first interconnect mechanism (110) comprises a first frame (120), a biasing member (140), a plurality of first electrical contacts (130), and a first projection (150). The second interconnect mechanism (160) comprises a second frame (170), a plurality of second electrical contacts (180), and a second projection (190). As the first interconnect mechanism (120) is moved toward the second interconnect mechanism (160), the contact between the first projection (150) and the second projection (190) causes rotation of the first frame (110) in a direction opposite the predetermined rotational direction.
