A second embodiment of a flat cable in line with the invention shall be defined under with reference to FIGS. So as to achieve the above object, the invention offers a versatile, shielded flat cable having a primary building which includes a base film, a plurality of strips of circuit conductor Juxtaposed on the base movie, a strip of ground conductor organized in parallel with the strips of circuit conductor, a cowl layer movie hooked up to the strips of circuit conductor and ground conductor, and a shield tape of a conductive metallic foil, made for instance of aluminum, copper or the like, extending over the cowl layer movie, the ground conductor being conductively connected to the shield tape, wherein the cover layer film is of a double layered development comprised of an higher cover layer movie having an space supplied with no higher layer film therein, and a lower cover layer movie, and wherein the ground conductor is uncovered, by means of the realm supplied with no upper layer film, to the shield tape so as to be connected with the shield tape. A pair of shield tapes 5 of a conductive steel foil are attached to the outer surfaces of the cowl layer film 4 and base movie, respectively, so as to shield the cable.

The flat cable of a web-like configuration includes circuit conductors 1 of a web-like configuration Juxtaposed on a base movie 3, and floor conductors 2 of a web-like configuration disposed on the base movie three in parallel relationship with the circuit conductors 1. The conductors 1, 2 are lined with a cowl layer film 4. A pair of shield tapes 5 of a conductive steel foil, fabricated from aluminum, copper, for instance, are shieldingly connected to the cowl layer movie 4, so that the bottom conductors 2 and the shield tapes 5 are conductively connected. FIG. 1 is a perspective view illustrating the development of a shielded flat cable in keeping with a first embodiment of the invention. A shielded flat cable in accordance with a second embodiment is characterized by a building wherein the decrease cover layer film of a predetermined dimension is positioned over the bottom film at a predetermined location thereof so as to electrically insulate the upper surface of the circuit conductors, the circuit conductors being provided within the upper surface of the bottom movie, the bottom conductor is disposed on the lower cover layer film, the ground conductor being arranged in parallel with the circuit conductors, and the higher cover layer movie is positioned over the base movie in an area together with the upper surfaces of the ground conductor and the lower cover layer movie in order to type a cable body, wherein an area having no higher cowl layer film is provided which extends alongside the intermediate portion of the decrease cowl layer movie and transversely of the cable physique, whereby the shield tape is connected to the floor of the cable body together with the realm having no higher cover layer movie so as to shield the cable body, and wherein the bottom conductor and the shield tape is conductively connected with each other via the realm having no higher cover layer film.

A shielded flat cable in response to a primary embodiment is characterized by a building whereby the lower cowl layer film is placed over the base movie provided, in the upper surface thereof, with the circuit conductors juxtaposed thereon, the bottom conductor is disposed on the decrease cover layer film in parallel relationship with the circuit conductors, and the higher cowl layer film is positioned over the lower cowl layer film and the higher floor of the bottom conductor in order to type a cable body, whereby the cable physique is provided, at predetermined locations thereof, with areas having no higher cowl layer movie which prolong transversely of the cable body, whereby the shield tape is positioned over the floor of the cable physique including the areas having no higher cowl layer film so as to shield the cable body, and whereby the bottom conductor and the shield tape are conductively linked with one another through the areas having no upper cowl layer movie. Several embodiments of a shielded flat cable in line with the invention will likely be explained under with reference to FIGS.

For comfort of illustration, shielded flat cables in prior artwork will be defined under with reference to FIGS. Thus, any such flat cable is disadvantageous, since it doesn't meet the requirement in the artwork in view of miniaturization and value financial savings of the flat cables. With the secondly talked about shielded flat cable in prior art, the ground conductor, 2 exposed exteriorly alongside the size thereof, could also be straight connected to the shield tape 5. Thus, the "less workability", "limitation in the house between the conductors", and "much less reliability in electrical connection", because of the presence of the connection home windows 6, talked about above could also be eliminated. Thus, connection home windows within the prior artwork may be obviated. The bottom conductor and the shield tape could also be electrically related with one another via the area having no upper cover layer movie, without the use of connection home windows in the prior art. The invention also permits surface-to-floor contact between the bottom conductors and shield tape, in order to extend stability of efficiency in electrical connection and shielding capacity. The performance in electrical connection between the bottom conductor and the shield tape is improved due to the surface-to-floor contact therebetween.
