Strain Relief Mechanism for Discrete Wire Cables

      Described is a strain relief mechanism for discrete wire
cables.  The mechanism is designed to provide a low cable bend radius
so as not to damage the discrete wires and to meet international
safety requirements for restraining strength.

      Strain relief mechanisms are readily available for restrain
relief of flat ribbon cables.  However, strain relief mechanisms are
not readily available to restrain cables made up of discrete wires
and to provide a low bend radius for cable harnesses.  The concept
described herein provides a strain relief mechanism to restrain
discrete wires and provides a low bend radius for the cable.  It also
provides restraint so as to meet international safety pull test
requirements.

      The strain relief mechanism consists of two parts.  Fig. 1a
shows the bottom part and Fig. 1b shows the top part.  In the bottom
part (Fig. 1a), two openings 10 provide for nine discrete wire
sections to be inserted into each opening. When the two nine wire
sections are positioned in a flat row, the top part (Fig. 1b) is
secured over the wire sections and held by three screws (not shown).
When the strain relief mechanism is placed onto the next assembly
(not shown), the flat discrete row positions provide a low bend
radius for the cable.

      The international pull test requirements are satisfied as a
result of groove 11 (Fig. 1a).  Groove 11 extends the entire length
of the bottom...
