A hinge assembly (200) for a clamshell-type electronic device includes a spindle (201) and casing sleeve (202). The hinge assembly (200) facilitates a single-split hinge. In addition to providing the mechanical hinging action, the hinge assembly (200) provides a reliable electrical connection between a first portion (502) and a second portion (601) of the clamshell device. The spindle (201) includes a nock (203) through which a linking member (304) of a flexible substrate (301) passes. The nock (203), having a semi-circumferential stop (206) bridging a first nock wall (204) and second nock wall (205), facilitates the electrical connection between an electrical circuit disposed in the first portion (502) of the electronic device and an electrical circuit disposed within the second portion (601) of the electronic device. In one embodiment, a hinge assembly (700) facilitates other components, such as an image capture device (720) being disposed within the hinge region of an electronic device.
