Connector

      Referring to the figure, the disclosed connector provides
a method for attaching a mass terminated cable to surface mount pads
1 on a printed circuit card or board.

      The connector consists of any multiple of contacts from 6 to 72
positions 2 molded into flame-retardant glass filled thermoplastic 3.
The contact base material consists of beryllium copper with an
overplate of nickel and tin lead. The contacts can be spaced on .100-
or .050-inch spacing depending on the pitch of the flat bulk wire
cable used to attach to the insulation displacement contacts (IDC) 4.
The connector contacts 5 are spaced and formed to allow for soldering
to the surface mount printed circuit pads on the cards or boards.
This depends on the density and selection of bulk wire and the number
of signal or power lines required.

      Staking pins or mechanical locking hardware is molded at the
ends of the connector 6 to provide support for the connector and to
eliminate mechanical stress on the surface mount solder connections.

      The cable terminations (IDC) consist of blades 4 that are
designed to accommodate mass termination of wire by piercing through
the insulation and making contact with the copper wire.  A cover 7
and strain relief 8 are used to hold the wires in place and help to
reduce mechanical movement of the wires in the IDC contact.  The
strain relief and cover would be installed after the cable is
terminated into the IDC...
