The card edge connector provides a fast means for
connecting/disconnecting single, double-sided or multi-
layer printed circuit boards.
Contact force consistency is obtained through the use
of a long cantilevered contact having a minimum
deflection angle and an extended self-cleaning, wiping
action. These contacts ensure positive connection to the
board, even when pad surfaces are irregular.
Good contact pressure is maintained with minimum
wear on PC board pads, even in hostile environments,
and after numerous insertions and withdrawals or shock
and vibration.
• Insulator protects contacts
from possible damage when
mated with PC board.
• Polarizing key slots allow
positive polarization without
loss of a contact position.
• Contact and cover
design provides for
reuse. Connector can
be reterminated easily
and reliably to a new
section of cable.
• Sturdy cover posts
provide protection
against cable pulls of
25 lb or more.
• Patented Torq-Tite™ contact
keeps conductor under constant
tension. Assures a mechanically
and electrically, sound, gas-tight
connection.
• Recessed slot
provide means for
non-destructive
removal of cover.

Card Edge Connector Features
• Compatible with various PC board thicknesses, from .032 in. to
• 10, 20, 26, 34, 40, and 50 contact versions.
• Lead-in on contact
helps align the conductor
with the IDC slot.
.070 in. thick.
• Standard gold-plated phosphor bronze contacts; tin-lead plated
contacts optional.
• Patented, offset tines
produce Torq-Tite™
termination for added
reliability.
• Can be daisy-chained or applied in cable end terminations.
• Factory pre-assembled cover minimizes assembly time.
• Available with or without mounting flanges.
• Dependable long cantilever contact design maintains consistent
pressure even after repeated matings with PC boards. Insures a
long insertion/withdrawal cycle life and a good self-cleaning wipe
on each PC board pad.
• Long cantilever
produces less angular
deflection as PC board
is inserted.
• Self-adjusting contact compensates for variations in PC board
thickness.
• Contact with the PC
board is made near the
face of the connector for
increased wiping action.
• Closed entry protection prevents possible damage caused by PC
board irregularities.
• Unsupported contact tail
allows for self-adjustment
to compensate for PC board
irregularities.
Strain Relief
Strain relief is an integral part of CW Card Edge connector. A
strain relief lip is molded into the connector body. Upon installation
of the cover, this lip causes a strain relief bend in the cable that
prevents forces applied to the cable from being transferred to the
IDC termination.
Polarization
Positive polarization is available on all CW card edge connectors.
A polarizing key, inserted into a V-slot located between any two
contacts, fits into a corresponding .037 in. slot cut into the PC
board. This technique not only provides positive polarization
without loss of a contact position, but also helps ensure precise
alignment of the contacts to the PC board’s pads.
Assembly
Assembling these connectors is both fast and easy using only a
simple bench press. The connector body is designed to orient the
cable to the contact tines, and the factory preassembled cover
permits termination of all conductors in one step–simply apply
opposing parallel forces on the connector cover and base.
