Abstract

The invention provides a flat shielded cable, capable of preventing the obstacle due to the whisker generated on a grounding part for grounding a shielded film with low cost. The flat shielded cable is formed in the way that a plurality of flat conductors (13) are arranged in parallel and coated by an insulated film (14), one surface of the flat conductors (13) is exposed from at least the end at one side to form a cable end part (12), the external surface of the insulated film (14) is covered by a shielded film (17). a grounding conductor (15) with the width of 0.15 to 1.0 mm is arranged on the insulated film near the exposed flat conductor portion of the cable and electrically contacts with the shielded film (17), a gold coating (19) is formed at least on the part exposed from the shielded film (17).

Description

technical field [0001] The invention relates to a shielded flat cable, which is composed of a plurality of conductors arranged in parallel and covered with an insulating film, and shielded by covering the outer side with a common shielding film, and at least one end has a The end portion of the connector to which the connection is made. Background technique [0002] Flexible flat cables (FFC) are used in many fields such as AV equipment such as CD and DVD players, OA equipment such as copiers and printers, and internal wiring of other electronic and information equipment for the purpose of space saving and easy connection. In addition, as the frequency used by the equipment increases, the influence of noise will increase, so a shielded flat cable with shielding is used. The shielding of the cable is formed, for example, by covering the outside of the FFC with a shielding film (for example, refer to Patent Document 1). [0003] In addition, the shielded flat cable has a ter...
