Introduction
The High Current Edge
family of connectors
provides high reliability and
economy in packages
compatible with industry
standards. While many new
card edge connectors for
signal applications have
moved toward higher density
configurations (0.050"
and 1 mm centerlines),
Tyco Electronics has
redesigned the 0.100"
standard edge product
family to carry more current,
for low power distribution.
This product family includes
the following:
■

■
R
The connectors serve low
durability cycle applications
which do not have the
available room for a
traditional 2-piece power
distribution connector. In
other applications, a low-
profile connector is needed
to allow for better airflow /
less airflow restriction.
This grouping of power card
edge connectors is focused
on providing high current
density with the favored
multi-point contact design
which reduces contact
interface resistance.
The connectors were
used originally in the ISA
Standard for computer
expansion cards. Today
these connectors are being
used in applications such
as; DC-to-DC converters,
low-wattage power
supplies, industrial grade
card extenders and general
low cost I/O applications
requiring durable/rugged
card edge contacts. The
improvements made still
allows use in the original
applications and they
provide a lower resistance
connection due to the high
conductivity contacts
plated with a minimum
30 micro inches gold.
The options include vertical
or right-angle PCB mounting
as well as straddle-mount
configurations for co-planar
PCB applications.

CROWN EDGE connectors
are a board-to-board power
interconnect solution that
uses ELCON high perform-
ance CROWN BAND
contact technology config-
ured to mate directly with
a printed circuit board edge
or — for higher currents —
with a solid bus bar. Power
and signal can be combined
and mounted end-to-end to
meet the requirements of
the applications.
Flexible Modular Design
To make easy work of
power distribution design,
CROWN EDGE connectors
are available in modules of
2 and 3 contact segments
with power or signal con-
tacts or a combination of
both in a single module.
Modules can be placed
end-to-end for assemblies
up to 8" (203.20 mm) long.
Custom molded configura-
tions are possible on high-
volume projects. Consult
Tyco Electronics or your
local Tyco Electronics sales
representative for details.
Versatile Power Arrangements
Opposing contacts are
isolated, so power connec-
tions at different voltage
levels can be on one side
of the board, with ground or
power return on the other
side.
True Hot-Plug Support
CROWN EDGE power mod-
ules that support current
interruption under load as
defined by safety regulatory
agencies are also available
for mating to a metal blade
or bus bar tab. These true
hot-plug modules allow cur-
rent interruption under load
by incorporating a contact
design that restricts the
effects of arcing to areas
that do not compromise the
integrity of the connection.
Product Highlights
High-current Card Edge
Interface
CROWN EDGE connectors
use Tyco Electronics proven
ELCON CROWN BAND
contacts that provide
multiple points of contact
for high current, and low
voltage drop and minimal
heat generation. The
desired current rating
for most applications can
be achieved by bussing
multiple contacts or even
modules. For even higher
currents, CROWN EDGE
connectors can be
mounted onto a bus bar,
and mate directly with a
bus bar tab. Optimum inter-
face to the mounting PC
board is achieved through
five termination tails.

Current Ratings
The chart below demonstrates the performance of the
CROWN EDGE power contact by showing the temperature
rise at different current levels applied to two power con-
tacts connected in series.
Current rating for any given application will depend,
among other things, on the module combination, PCB
copper trace volume, and internal equipment tempera-
ture/air flow. Mounting and mating to a bus bar will
increase current ratings.
Safety Regulatory Compliance
CROWN EDGE connectors have been evaluated by
Underwriters Laboratories and have been found to comply
with the requirements of U.S. standard UL1997 and
Canadian standard C22.2 No. 182.3-M1987.
Compliance with Current Interruption Requirements
Hot-plug CROWN EDGE modules are available for appli-
cations that require current interruption as defined by
safety regulatory agencies. These power-only modules
have been evaluated and recognized by Underwriters
Laboratories for current interruption up to 50 cycles as
per the UL1977 standard. See hot-plug requirements on
page 180.
