(SSI) Expandable Power & Signal Connectors
INTRODUCTION
Molex’s successfully introduced a new series of power connectors
that conform to Server System Infrastructure (SSI) open specification
(http://www.ssiforum.org). The DPS and MPS offer a standard
variation of 2 & 11 power blades with mixed layout of 24 signal
pins. The contact support up to 30 amperes of current. With demand
for more flexibility and options in variations, Molex have further
expanded the series to cater to the needs and requirement from our
customers.
They feature recessed signal-pins and sequential mating (Last-Mate-
First-Break) that allows hot-swapping of power supply units on the
male side. The receptacle could also provide for LMFB with recess
power blade. The selection options include any number of power (up
to 20) or signals (up to 128), placing power or signal at different
location, fork lock or screw mount, AC or DC current (different pitch),
Guide post option, Standard and Long Power blades. Molex offers
standard through-hole right angle headers and receptacles as well as
through- hole and press fit vertical receptacles.
FEATURES AND BENEFITS
Recessed pins-sequential mating (Last-Mate-First-Break) allows
hot swapping of power supply units
Guide Pockets (headers) or guide posts (receptacles) facilitate
easy blind-mating
Shrouded headers prevent contact damage
Stamped and selectively plated power contacts provide greater
electrical reliability
Rigid tails for easy PCB insertion
Metal forklocks or screw mounts for strong board retention
reduce board warpage during soldering
High temperature thermoplastic housing material ensures
thermal reliability
