  • Patent number: 6551125
    Abstract: A connecting structure for a portable electronic device cord comprises a substantially arc-shaped binding member having an outwardly convex surface projecting toward the interior of the device case from an opening in the case through which the cord passes, the binding member forming an integrated single unit with an interior wall of the case. The cord, one end of which is secured to a board within the device, is wrapped around the surface of the arc-shaped binding member and thereby bent at substantially a right angle as it extends through the binding member by which it is securely held and out the case opening. By firmly securing the cord to the case in this fashion the need for an external bush is eliminated and the cord can be wrapped snugly around the device without bending at sharp angles, thus increasing ease of transport and reducing the possibility of the cord breaking loose from the device.
