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.

• Patented Torq-Tite™ contact

keeps conductor under constant

tension. Assures a mechanically

and electrically, sound, gas-tight

connection.

• Sturdy cover posts

provide protection

against cable pulls of

25 lb or more.

• Recessed slot

provide means for

non-destructive

removal of cover.

Card Edge Connectors

Con tact

• Lead-in on contact

helps align the conductor

with the IDC slot.

• Patented, offset tines

produce Torq-Tite™

termination for added

reliability.

• Long cantilever

produces less angular

deflection as PC board

is inserted.

• Contact with the PC

board is made near the

face of the connector for

increased wiping action.

• Unsupported contact tail

allows for self-adjustment

to compensate for PC board

irregularities.

Car d Edge Con n ector Featur es

• 10, 20, 26, 34, 40, and 50 contact versions.

• Compatible with various PC board thicknesses, from .032 in. to

.070 in. thick.

• Standard gold-plated phosphor bronze contacts; tin-lead plated

contacts optional.

• 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.

• Self-adjusting contact compensates for variations in PC board

thickness.

• Closed entry protection prevents possible damage caused by 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.

Polar ization

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.
