45711-1000 Datasheet, PDF (1/2 Pages) Molex Electronics Ltd. – Bus Bar Connector (BBC)

FEATURES AND SPECIFICATIONS
Hot-Pluggable, High-Current Bus Bar Connector
(BBC) Provides An Easy Blind-Mate Connection
New telecommunication and high-end computing
equipment require increasing amounts of current
from power supplies. To meet this challenge, Molex is
pleased to expand its product offering of high-current
connector solutions with the BBC.
The BBC is a compact, high current connector for
direct mating of two perpendicular power bus bars in
a power supply or switching power supply application.
Rated up to 320.0A, the BBC offers over 20% more
current than competing products. The higher current
provides increased power or safety factor for customer
applications. The high performance, contact design
offers true hot pluggability. The parallel contacts free-
float within the BBC housing to facilitate blind mating
with the bus bar tab.
The BBC’s mounting dimensions are identical to
competing connectors for easy second sourcing
opportunities.

Features and Benefits
■ Top entry of the connector mates with a standard
25.40mm (1.000”) wide by 3.18mm (.125”) thick
bus bar tab which facilitates mating with de facto
output blades for typical power supply applications
■ Rated up to 320.0A for high-current applications
■ Isolated left and right contacts provide option for
power feed and return when BBC is mounted to a
laminated bus bar
■ Rated for current interruption (Safety agency
approvals pending) to match true hot-plugging
requirements
■ Low-voltage drop for minimal heat generation
■ Float-mount design provides up to 6° of
misalignment to blind-mate with bus bar tab
■ Mounts to a bus bar via two, 4.32mm (.170”)
diameter holes using customer supplied (8”x32”
thread) machine screws providing screw-mount
design for secure fastening to bus bar
■ Dimensionally compatible with competitive
connectors assures drop-in replacement for second
source opportunities
