A shielded flat cable in response to a second embodiment is characterized by a building whereby the lower cover layer movie of a predetermined measurement is positioned over the base film at a predetermined location thereof so as to electrically insulate the higher floor of the circuit conductors, the circuit conductors being supplied in the higher floor of the base film, the bottom conductor is disposed on the lower cowl layer movie, the ground conductor being arranged in parallel with the circuit conductors, and the upper cover layer movie is positioned over the bottom film in an area together with the upper surfaces of the bottom conductor and the lower cover layer movie in order to form a cable body, whereby an area having no higher cowl layer movie is provided which extends alongside the intermediate portion of the decrease cover layer film and transversely of the cable body, whereby the shield tape is hooked up to the surface of the cable physique together with the world having no higher cover layer film so as to shield the cable physique, and wherein the ground conductor and the shield tape is conductively linked with each other by means of the realm having no higher cover layer movie.

A shielded flat cable in keeping with a first embodiment is characterized by a development wherein the lower cowl layer movie is positioned over the bottom film offered, in the higher surface thereof, with the circuit conductors juxtaposed thereon, the ground conductor is disposed on the decrease cowl layer movie in parallel relationship with the circuit conductors, and the upper cover layer movie is positioned over the lower cowl layer movie and the upper floor of the bottom conductor so as to kind a cable physique, wherein the cable body is provided, at predetermined places thereof, with areas having no upper cover layer film which prolong transversely of the cable body, whereby the shield tape is placed over the floor of the cable physique including the areas having no upper cover layer film so as to shield the cable body, and wherein the ground conductor and the shield tape are conductively related with one another by the areas having no upper cover layer movie. 7 and 8, circuit conductors 1 and ground conductors 2 that are alternately juxtaposed on a base movie 3. A cowl layer film four is adhesively placed over the conductors 1, 2, so that the conductors are sandwiched in between the bottom film 3 and the cowl layer movie 4. Several parts of the cover layer movie four are cut out to kind small connection windows 6 by way of which the ground conductors 2 are exteriorly exposed.

In order to achieve the above object, the invention provides a flexible, shielded flat cable having a basic development which contains a base movie, a plurality of strips of circuit conductor Juxtaposed on the bottom movie, a strip of floor conductor arranged in parallel with the strips of circuit conductor, a cover layer film hooked up to the strips of circuit conductor and ground conductor, and a shield tape of a conductive metal foil, made for example of aluminum, copper or the like, extending over the cover layer movie, the ground conductor being conductively related to the shield tape, whereby the cover layer film is of a double layered building comprised of an upper cover layer movie having an space supplied with no higher layer movie therein, and a decrease cover layer film, and wherein the ground conductor is uncovered, by means of the world supplied with no higher layer movie, to the shield tape in order to be connected with the shield tape. FIG. 1 is a perspective view illustrating the development of a shielded flat cable in accordance with a first embodiment of the invention.

Numeral varieties of shielded flat cables are identified within the art. Such grounding constructions may be categorized into two varieties as summarized beneath. For instance, the ground conductors 2 and the circuit conductors 1 may be organized in an acceptable manner other than the alternate association point out above. Accordingly, reduction in shielding impact as a result of limitation in association of the ground conductor(s) may be prevented. Thus, the circuit conductors and the bottom conductor could also be electrically insulated relative one another by way of the lower cover layer movie. The flat cable of an online-like configuration consists of circuit conductors 1 of an online-like configuration Juxtaposed on a base film 3, and floor conductors 2 of an internet-like configuration disposed on the bottom movie 3 in parallel relationship with the circuit conductors 1. The conductors 1, 2 are lined with a cover layer movie 4. A pair of shield tapes 5 of a conductive metal foil, product of aluminum, copper, for example, are shieldingly hooked up to the cowl layer movie 4, so that the ground conductors 2 and the shield tapes 5 are conductively linked.
