A shielded electric cable having a core including an insulated conductor. A first shielding member formed of an elongated ribbon of insulating material and a pair of elongated metal foil strips arranged in a parallel relationship with the ribbon and bonded to the opposite sides of the ribbon is applied longitudinally to the core and wrapped circumferentially therearound forming two concentric substantially closed shielded layers. A layer of plastic material, preferably foamed, surrounds the first shielding member and a second shielding member surrounds the plastic layer, the second shielding member being formed of non-braided metallic material. The layer of plastic material is bonded to the shielding members. The shielded electric cable is provided with an outer jacket of non-conducting material and having an appropriate O.D. for receiving a standard connector.
A shielded electric cable of predetermined diameter for assembly with a standard connector comprising a core comprising an insulated conductor, a first shielding member comprising an elongated ribbon of insulating material and a pair of elongated metallic foil strips arranged in a parallel relationship with the ribbon and bonded to opposite sides of the ribbon, the first shielding member being applied longitudinally to the core and wrapped circumferentially around the core in a generally parallel relationship forming two concentric, substantially closed shielding layers, a layer of plastic material of predetermined thickness surrounding said first shielding member, and a second shielding member surround said layer of plastic material, said second shielding member being formed of non-braided metallic material to facilitate assembly of the cable with a standard connector.
A method of making a shielded electric cable of predetermined diameter for assembly with a standard connector said cable having a core comprising an insulated conductor including the steps of applying a first shielding member to the core, the first shielding member comprising an elongated ribbon of insulating material and a pair of elongated metal foil strips arranged in a parallel relationship with the ribbon and bonded to the opposite sides of the ribbon, the first shielding member being applied longitudinally to the core and wrapped circumferentially around the core in a generally parallel relationship forming two concentric substantially closed shielding layers, applying a layer of plastic material of predetermined thickness surrounding the first shielding member, applying a second shielding member surrounding the layer of plastic, the second shielding member being formed of non-braided metallic material to facilitate assembly of the cable with a standard connector, and applying an outer jacket of non-conductive material to the second shielded member to complete the shielded electric cable.
A method of assembling a shielded electric cable with a connector wherein the connector comprises a central connector post surrounded by a crimp ting and a connector nut and the shielded electric cable comprises a core having an insulated conductor, a first shielding member extending longitudinally of the core and wrapped circumferentially around the core, a layer of plastic material surrounding the first shielding member and a second shielding member surrounding the layer of plastic material, the second shielding member being formed of non-braided metallic material, said method comprising the steps of:
