Abstract

Disclosed is a method of inserting a relatively limp cable through confined channel apertures by first placing the cable within a semiflexible tube that supplies stiffness to enable threading of the tube with cable through otherwise inaccessible spaces. Cable kinking is avoided and easy negotiation of gentle channel curves achieved while pushing from one end. This is suitable for a rapid change of a defective cable section during servicing, also for Plant customization of electronic/electric machines by interchange of feature cables.

Cable Tubes

      Disclosed is a method of inserting a relatively limp cable
through confined channel apertures by first placing the cable within
a semiflexible tube that supplies stiffness to enable threading of
the tube with cable through otherwise inaccessible spaces.  Cable
kinking is avoided and easy negotiation of gentle channel curves
achieved while pushing from one end.  This is suitable for a rapid
change of a defective cable section during servicing, also for Plant
customization of electronic/electric machines by interchange of
feature cables.

      Cable tubes comprise a surrounding structure not necessarily
closed, with varying degrees of rigidity to suit conditions of
congestion and curvature of a channel, that can be pushed or pulled
down said conduit or channel taking the cable contained in the tube
from one end of the conduit or channel to the other.

      This concept of loading cables into a tube and then fitting the
tube through a conduit permits cable replacement through a confined
space without the use of special tools, or drawstrings, nor the need
to replace complete wiring harnesses.  It allows cable forms to be
modularized with ensuing advantages.

      By fitting a cable into a stiffening structure that may also be
flexible to varying degrees, allows considerable reduction in
serviceability cost through the facility with which sections of cable
can be removed and replaced as required, particularly through curved
ducts.  It is...
