Power Connectors & Interconnection Systems
Domino Series Connectors
The ELCON Domino
connector system is a
modular high-current
connector system consisting
of interchangeable modules
which can provide AC,
DC, logic and signal,
float mounting, and pin
sequencing. All Domino
modules incorporate
CROWN BAND technolo-
gies, tried and tested under
the most arduous conditions.
The high current capabilities
virtually eliminate the need
for bussing or splitting
current, with resulting space
savings and economies.
The Domino connector
system allows the user to
configure a connector
specific to an application,
from off-the-shelf
components. It can be
purchased as separate
modules and assembled
by the user, but is more
generally ordered as a

connector assembly using
an assembly part number
which Tyco Electronics
assigns to a specific
configuration. Consult
Tyco Electronics for
assistance in laying out a
new connector. If required,
Domino connector
assembly is simple: once
the locking rails are cut to
size, the only tool required
is a Phillips screwdriver for
tightening the end-caps.
Most Domino contacts
are the same as used in
ELCON drawer connectors.
Modules A through E and R
are sold as housings with
retention clips; the contacts
are ordered separately.
See page 80 for available
contact options and plating
information, page 67 for
tooling. Modules K, L, and
M are sold pre-loaded
with contacts. Domino
assemblies are shipped
complete with contacts.

The Domino system is ideal
for use with hot-pluggable
power supplies of the type
employed for load-sharing
and/or redundant power for
computer systems. Current
interruption capability is
standard in the L module
and an available option in
the A module.
The CROWN BAND contact
is a small louvered cylindri-
cal receptacle of beryllium
copper. Manufactured on
progressive dies to allow
consistent, even insertion
and withdrawal forces,
its design helps ensure
maximum surface contact
area for minimum voltage
drop and minimum heat
generation. CROWN BAND
contacts also provide excel-
lent shock and vibration
resistance.
