Abstract
A core is capable of being utilized within a conduit in a push-pull type remote control cable assembly. The core has a metallic wire member and includes a coating around the wire member which has an outer layer of TFE resin. An inner layer of the coating includes FEP resin which is bonded to the wire member to secure the coating thereabout.
Claims13
A core capable of being utilized within a conduit in a push-pull type remote control cable assembly, said core comprising:
- a metallic wire member including a plurality of helically wound strands of wire having at least one flat wire helically wound about an outer surface of plurality of said strands with axial space between adjacent convolutions to provide a substantially even outer surface for said wire member;
- at least a partial coating on said wire member including an outer layer of TFE resin;
- and an inner layer of said coating include FEP resin bonded to said wire member to secure said coating to said wire member, said FEP resin layer extending into said space.
A push-pull type remote control cable assembly comprising:
- a conduit having an inner surface of nylon;
- a core disposed inwardly of said conduit and capable of being axially displaced relative to said conduit;
- said core having a base metallic material and at least a partial coating about said metallic material;
- and
- said coating having an outer surface of TFE resin to provide a low-friction contact between said coating and said inner surface of said conduit and an inner surface of FEP resin which is bonded to said metallic material to secure said coating thereabout.
A core capable of being utilized within a conduit in a push-pull type remote control cable assembly, said core comprising:
- a metallic wire member;
- at least a partial coating on said wire member;
- said metallic wire member including a plurality of helically wound strands of wire having at least one flat wire helically wound about an outer surface of a plurality of said strands to provide a substantially even outer surface for said wire member with an axial space between adjacent convolutions of said flat wire and said coating extending into said space.
