Pull Tab/Strain Relief

      This device eliminates cable damage caused by handling.
The damage occurs primarily during plugging and unplugging of the
connector, or a nearby connector on the same cable.

      This device (Fig. 1) combines several features (available
separately by other means) into one part.  It is a handle for
installing a connector, a handle for removing a connector and a
strain relief to eliminate cable damage.

      This device is used on IDC (insulation displacing connector)
connectors.  It would be installed between the IDC connector and a
commercially available strain relief, as shown in Fig. 2.  This
device is substantially taller than the catalog "strain relief".  The
additional height combined with the shape offers the service person a
better grip for inserting and extracting the connector.  This easier
to grip part encourages the service person to use the pull tab
instead of pulling on the cable and subsequently damaging the cable.

      The "wings" are part of the device lay on the cable and are
taped to the cable to afford further protection from damaging the
cable.  Serious cable damage is common because of uncontrolled
flexing and/or stress at the junction of the cable and connector.
Attaching the cable to the "wings" distributes these forces away from
the critical failure area.

      In areas that require different cable routing, the wings can be
folded back against the handle with the cable trapped between the
