摘要:
A connecting configuration for a flexible wired circuit board includes a first terminal member, a second terminal member, and a flexible wired circuit board having a conductive pattern for electrically connecting the first terminal member and the second terminal member. The first terminal member and the second terminal member are provided such that at least one of the terminal members is linearly movable to be adjacent to and apart from the other terminal member. The flexible wired circuit board is provided to be wound or twisted in the middle of the moving direction.

A wired circuit board has an insulating layer extending in a longitudinal direction, a conductive layer having a plurality of signal wirings covered with the insulating layer and arranged in mutually spaced-apart and parallel relation in a perpendicular direction to the longitudinal direction and a thickness direction of the insulating layer, and connecting terminals provided on both longitudinal ends of each of the signal wirings and exposed from the insulating layer, and a ground layer covered with the insulating layer and formed to surround each of the signal wirings in a perpendicular direction to the longitudinal direction. A slit along the longitudinal direction is formed between each of the signal wirings in the insulating layer.

A substrate for mounting a preamp chip thereupon, fabricated using a stiffener layer made of a conductive material; an insulating layer provided over the circuitry area of the substrate; a circuitry made of a conductive material provided over the insulating layer; and a flap which is an extension of the stiffener layer having no insulating layer provided thereupon. The flap is fabricated to fold over the preamp chip to remove heat therefrom.
