Embodiment Construction

[0018] see figure 1 , the flat flexible cable provided by the present invention includes an electrical transmission unit, an optical transmission unit, an elastic support 3 and a multi-layer protective layer 1 covering the electrical transmission unit, the optical transmission unit and the elastic support 3, the multiple The cross-section of the protective layer 1 is elliptical, the elastic support 3 extends along the short axis of the ellipse and supports the multi-layer protective layer 1, and the electrical transmission unit and the optical transmission unit are respectively arranged on the Both sides of the elastic support 3 are symmetrically distributed along the long axis of the ellipse, and neither the electrical transmission unit nor the light transmission unit contacts the multi-layer protective layer 1 and the elastic support 3 . The multi-layer protective layer 1 is filled with a filling material 2 , and the elastic modulus of the filling material 2 is smaller than ...

Abstract

The invention provides a flat type flexible cable. The flat type flexible cable comprises an electrical transmission unit, an optical transmission unit, an elastic supporting piece and a multilayer protection layer coated outside the electrical transmission unit, the optical transmission unit and the elastic supporting piece, wherein the cross section of the multilayer protection layer is in the shape of an ellipse; the elastic supporting piece extends along the short axis of the ellipse and is used for supporting the multilayer protection layer; the electrical transmission unit and the optical transmission unit are arranged on two sides of the elastic supporting piece respectively, and are symmetrically distributed along the long axis of the ellipse; and the electrical transmission unit or the optical transmission unit is not in contact with the multilayer protection layer and the elastic supporting piece respectively.

Description

technical field [0001] The invention relates to a cable, in particular to a flexible cable provided with an optical cable tube and a photoelectric integrated cable used for dual transmission of electric power and digital signals between communication equipment and user terminals. Background technique [0002] In international application WO 97 / 40504 a self-supporting cable is described which has a shielding band around an insulated electrical conductor which effectively protects the cable when it is suspended from a fixed point. The cables can be equipped with tubes in the above mentioned areas. International application WO 2004 / 006272 describes a cable having a shielding strip of partially conductive material which is laid along the cable in the region between the insulated electrical conductor and the cable sheath. Conductive wires are laid in the strip along its entire length and form an effective shield to cut off the cable voltage if the cable is penetrated by a conduc...
