Abstract
A composite cable has a reinforcing layer with conductors disposed on opposed planar surfaces. Dielectric film layers electrically separate the conductors on the planar reinforcing layer from respective layers of additional conductors. The flexible cable is manufactured by laminating a layer of dielectric film and a layer of electrically conductive material onto both sides of a double clad core which provides a strain relief reinforcement for the cable.
Claims8
A flexible cable for conducting electrical signals comprising:
- a planar core member formed of a first dielectric material for strain relief reinforcement and bending flexibility, said planar core member having upper and lower planar surfaces;
- two layers of a first electrically conductive metallic material which are respectively disposed on the upper and lower planar surfaces of the core member in contiguous relationship with the planar surfaces, wherein the two layers of the first electrically conductive metallic material are securely attached to the planar core member;
- two layers of dielectric film comprised of a second dielectric material and which are superimposed on and in contiguous relationship with said layers of the first electrically conductive metallic material;
- and
- two layers of a second electrically conductive metallic material which are respectively disposed on the layers of dielectric film in contiguous relationship with the layers of the dielectric film.
