Design and Construction
The plug connector shall be a multi-piece assembly having single row of contacts in the mating
area which dividing into signal segment (S1-S7) and power segment (P1-P15) or either one which
transition out to either surface mount style or solder style soldertail to accommodate various P.C.
board thickness. The contact pattern in the mating area will have short and long terminals in a
specific pattern that results in a 0.5mm (0,020’) differential between contact points in the long and
short terminals. (This allows for first mate-last break capability - see respective product prints for
location of short and long terminals.)
The receptacle connector shall be a multi-piece assembly having single row of contacts in the
mating area which dividing into signal segment (S1-S7) and power segment (P1-P15) which
transition out to a in-line or stagger through hole pattern or surface mount pad. The contact pattern
in the mating area will have short and long terminals in a specific pattern that results in a 0.5mm
(0.020”) differential between contact points in the long and short terminals. (This allows for first
mate-last break capability – see respective product prints for location of short and long terminals.)
The receptacle hold down terminal has the board retention features that secure the connector to
the board in preparation for solder reflow (through-hole) or board termination (press-fit).
A polarization peg (optional) on the bottom of the connector housing assures proper connector
orientation during board mounting. The receptacle through hole connector and press fit connector
are designed to terminate to board thickness of 1.57mm (0.062”), 2.36mm (0.093”) and 3.18mm
(0.125”). Visual examination of connectors to be done per EIA 364-18.
5.4.1
5.4.2
Mating. The connectors shall be capable of mating and unmating manually without the
use of special tools.
Workmanship. Connectors shall be uniform in quality and shall be free from burrs,
scratches, cracks, voids, chips, blisters, pin holes, sharp edges, and other defects that
will adversely affect product’s life or serviceability.
