IDC connector preserves signal integrity
Patented connector mates with ribbon cable for high-density,
high-performance applications
W.L. Gore's Transconnect connector corrects a problem with its
several-years-old Ribbon-Ax cable (Electronic Products, Oct. 1989, p. 55).
The cable broke ground by offering users the performance of a coaxial
cable with the mass-termination ease of a ribbon cable. However, the
cable's high signal performance often degraded at the connector. The new
connector preserves the high-speed, controlled impedance throughout the
entire signal path. The Transconnect connector is designed primarily for
use with the Ribbon-Ax cable. But it can also mate with other 28 to
30-gauge ribbon cables in applications requiring controlled impedance and
high frequency. The connector has a metallized connector body and
dielectric insert. This patented design brings the cable shields into
close proximity with the connector body and maintaining a controlled 50-
or 75-ohm impedance, thus preserving signal integrity throughout the
mated connection (see diagram). Moreover, it allows all positions in the
connector to function as signals. Signal density can be up to 100
signals/in. Completing the connector assembly is a board-mounted PGA
socket with a latch-and-eject lever. This makes it possible to replace the
connector without desoldering it from the pc board. The connector
maintains line isolation under -60 dB at a 1-ns rise time. Contact rating
is 3 A. Contact resistance is just 0.008 ohms. Frequency rating is 1,000
MHz, and maximum temperature 150 degreesC. ($1.50 to $2 per mated
line/small qty–8 weeks.) W.L. Gore & Associates, Inc. Phoenix, AZ
