Abstract

The metal shroud for a connector provides a ground path to the mating connector, a surface for thumbscrew retention, a surface for attaching the shield, and a feature that provides adhesion to the overmold. This is a method by which the small computer system interface (SCSI) as well as other high density connectors that are used for external cables or terminators can be packaged.

High Density "D" Shell to Cable Shield Termination

       The metal shroud for a connector provides a ground path
to the mating connector, a surface for thumbscrew retention, a
surface for attaching the shield, and a feature that provides
adhesion to the overmold. This is a method by which the small
computer system interface (SCSI) as well as other high density
connectors that are used for external cables or terminators can be
packaged.

      In Fig. 1, the metal shroud 1 is deepdrawn to form a shield
around the pins.  There are numerous detents 2 on each side of the
metal shroud.  These detents provide a low resistance connection and
form a ground path to the mating connector.  A flat surface 3 with
holes at each end of the metal shroud provide proper spacing and a
surface area for the thumbscrews 4 to secure the connectors when
mated.

      The terminator card assembly 5 or terminated cable connector 6
is then attached to the metal shroud 1 and premold 7 is added around
the terminator card 5 or terminated cable connector 6, but does not
cover the metal shroud 1.

      In Fig. 2, the premold assembly 8 is wrapped with copper tape.
The copper tape is soldered 9 to the metal shroud to form continuous
shielding around the card assembly or terminated cable connector,
providing a ground path to the metal shroud.  The copper tape is
soldered to the cable shield when using a shielded cable.  This
provides a continuous shield and ground path.
