Optical Link Card Guide/Retention System

      An optical link card guide and retention system is disclosed.
Mechanical assist and modular design functions are incorporated into
the system to allow for installation and replacement in a customer
environment.

      A single piece molded plastic housing is shown as the basic
building block for the guiding system.  It incorporates features for
the latching and mechanical advantage requirements in the customer
access area, provides keying in conjunction with the link card cover
features, minimizes airflow obstruction, and contains features for
adding electro-magnetic interference grounding points.

      The latching mechanism is a single plastic molded lever
arm/catch latch that assembles to the optical link card covers and
pivots on link card cover pins.  The latch, when closed, remains
outside of the optical cable access area but is low profile to allow
for stacking of link cards.

      Guiding tolerances are held sufficiently tight to meet
connector offset requirements for making blind connections.  The
basic guide housing can be molded as a single piece for multiple
cards as well as for single cards depending on the using system
package.  Features may be added to the mold to allow for fastening of
the housing to next level packaging.  Guide pins may be molded in the
housing to allow the housing to seat and position itself in
additional levels of packaging where necessary.
