PV
MIL-C-26482, Series 2 Connectors
• Intermatable with MIL-C-26482 Series I
• Operating temperature – 55 C to + 200 C
The PV Connector is designed to meet the rugged require-
ments of MIL-C-26482, Series 2/MIL-C-83723 Series I*, the
specification which delineates the critical requirements of
space-age applications. PV Connectors have been used
extensively on major aerospace programs requiring gener-
al-purpose, miniature cylindrical bayonet coupling connec-
tors such as Space Shuttle, Apollo, ATM, OWS
Minuteman, Skylab, Thor-Delta, Titan IIIC and Viking.

The PV series is an important member of the Universal
Interconnect System (UIS) – the only system that can per-
form all interconnection missions. This system is adapt-
able for use with connectors of all shapes and sizes,
including circular and rectangular configurations, stan-
dard, miniature, and subminiature sizes. UIS is a rear serv-
icing s system that evolved form the LITTLE CAESAR ®
rear release contact retention assembly, pioneered and
developed by ITT Cannon. Since this time, ITT Cannon,
and its licensees, have supplied to industry over 250 mil-
lion interconnections utilizing this system.
PV7 connectors are available under numerous industrial
specifications, some of which are listed below:
- CS512089 Jet Propulsion Laboratory
- 40M39569 NASA, George C. Marshall Space Flight
Center
- 81D52 Martin Marietta, Denver Division
- MG414-0365 Rockwell International Space Division
- AC414-0013 Rockwell International Autonetics Division
- STS0003 McDonnell Douglas Astronautics
This connector series is manufactured to accommodate
the following backshells: M85049/31 (MS3416),
M85049/51 (MS3418), and M85049/52 (MS3417).
Backshells are not included with connector and must be
ordered separately. Backshells on page A-67 are Non-MS
type.

1. Universal Insertion / Extraction Tool Style
– A single, expendable
plastic tool is used for insertion and extraction of both pins and
sockets.
2. Simple, Strong Contact Design
– One basic configuration
eliminates undercuts and maximizes bend resistance for
positive contact mating.
Closed-Entry Socket Insert
– Hard dielectric socket face of
mating connector has lead-in chambers for positive alignment
of pins and sockets.
3. Interfacial Pin Insert Seal
– Universal interconnect permits design
of raised moisture barriers around each pin which mate into
lead-in chambers of hard face sockets insert for individual contact
sealing. Interfacial sealing is never touched by service tools.
4. Superior Contact Stability
- Rear Contact Release System (LITTLE
CEASAR contact assembly) features a stamped metal retaining clip
captivated by molded-in shoulders of each contact cavity in the
insulator. A rear-inserted plastic tool expands at tines beyond the
contact shoulder, releasing the contact.
Polarized Backshells
– Interlocking teeth on the front of the
backshell and rear portion of the shell allow endbells to be
positioned as desired, eliminating chafing of wire during assembly.
