MIL-C-26482, Series 2 Connectors

• Intermatable with MIL-C-26482 Series I

• Operating termperature - 55˚C to + 200˚C

The PV connector is designed to meet the rugged

requirements 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 general-purpose,

miniature cylindrical bayonet coupling connectors

such as Space Shuttle, Apollo, ATM, OWS Min-

uteman, 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 perform all interconnection mis-

sions. This system is adaptable for use with connec-

tors of all shapes and sizes, including circular and

rectangular configurations. standard, miniature and

subminiature sizes. UIS is a rear servicing system

that evolved from the LITTLE CAESAR® rear re-

lease contact retention assembly, pioneered and

developed by ITT Cannon. Since this time,

ITT Cannon, and its licensees, have supplied to

industry over 250 million interconnections utilizing

this system.

PV7 connectors are available under numerous in-

dustrial 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 accommo-

date the following backshells: M85049/31

(MS3416), M85049/51 (MS3418) and M85049/

52 (MS3417). Backshells are not included with

connector and must be ordered separately. Back-

shells on page 161 are Non-MS type.

Universal Insertion / Extraction Tool Style

- A

single,expendable plastic tool is used for insertion and

extraction of both pins and sockets.

Simple, Strong Contact Design

- One basic config-

uration eliminates undercuts and maximizes bend re-

sistance for positive contact mating.

Closed-Entry Socket Insert

- Hard dielectric socket

face of mating connector has lead-in chamfers for

positive alignment of pins and sockets.

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.

Superior Contact Stability

- Rear Contact Release

System (LITTLE CAESAR 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 the 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 chaf-

ing of wire during assembly.
