3.4.5.4 Mounting and Mating Hardware. Mounting and mating hardware shall be corrosion
resistant steel per QQ-S-763, ASTM A484 or ASTM A582. Hardware parts for use
with anodic and electroless nickel shell finishes shall be passivated per QQ-P-35.
Hardware parts for use with cadmium plated shells shall be cadmium plated per QQ-P-
416.
3.4.5.5 Elastomeric Seals. Elastomeric seals shall be resilient dielectric material per the
applicable specification control drawing.
3.4.5.6 Connector Inserts. Connector inserts shall be rigid thermoplastic dielectric material per
the applicable specification control drawing.
3.5 Design and Construction Requirements. Connectors shall be designed and constructed
to withstand handling during installation and maintenance. Complete connectors shall
consist of a rectangular plug or receptacle shell; fixed or removable insert(s) with fixed
pin or socket contacts; mounting/mating hardware and, where appropriate, a cable
clamp.
3.5.1 Shells. Plug and receptacle shells shall meet the following requirements:
3.5.1.1 Shells for EME-Shielded Connectors. Plug shells for EME-shielded connectors shall
have spring fingers which contact the receptacle shell prior to engagement of the
contacts.
3.5.1.2 Shells for Pressure-Maintaining Connectors. Shells for pressure maintaining connectors
shall have mounting flanges and elastorneric gaskets for sealing the flange to a panel.
3.5.1.3 Coupling.
Coupling between mating connectors shall be accomplished by means of
two captive jackscrews on the plug shell. Jackscrew threads shall conform to FED-
STD-H28 and shall be self-locking per MIL-F-18240. Jackscrews shall provide
sufficient force to effect a moisture seal between the socket contact insert and the
elastomeric interfacial seal on the pin contact insert. Complete coupling shall occur
when the jackscrews are torqued to 9 lbf-inch (1.0 N-m) as prescribed in Raychem ES
61115 (MTC100) or ES 61257 (MTC50).
3.5.1.4 Polarozation. Shell polarization shall prevent the mating of any plug and receptacle
shells if the connectors are not in the correct mating position. Polarization of shells
shall occur before connector keying.
3.5.1.5 Connector Keying.
Insertable keying pins shall provide a minimum of 16 different
keying combinations. Keying shall prevent the mating of any plug and receptacle not
properly keyed. Connector keying shall occur before engagement of contacts or
coupling hardware.
