  • Patent number: 5435052
    Abstract: A motion transmitting remote control assembly (10) includes a flexible remote control core element (12) and a conduit (14) which slideably supports the core element. The conduit (14) has a jacket (16) defining an outer surface and an inner bore. A liner (18) lines the inner bore and includes an end protruding from an end of the jacket. The conduit (14) also includes a plurality of lay wires (20) having ends protruding from an end of the jacket (16) together with the liner (18). The ends of the lay wires (20) are formed to have an arch-shaped protrusion (22,26) which protrudes radially from the end of the liner (18). Such a protrusion (22,26) forms a mechanical lock between the conduit (14) and an end fitting (24) which is molded over the end of the conduit, preventing axial movement between the end fitting and the conduit.
