  Round Shell Connectors  
     
 

Cylindrical Threaded Coupling Connectors are available for manu applications from commercial / industrial use to the most stringent, high reliability military and space applications. They provide for minimum effort in usage and therefor, high economy upgrades for existing applications and provide for simplified design for new and interface equipments. High quality manufacturing processes and materials combine with exacting design standards to ensure optimum performance and reliability under an extreme range of hostile environment conditions. These threaded coupling connectors are designed and manufactured in conformance with JSS 50812 and MIL-C-5015.

JSS 50812/MIL-C-5015 designates serval classes of connectors to meet different requirement. Class designations and brief descriptions are listed below

  
     
 
A- Solid Shell for general, non-environmental applications.
C- Pressurized- for use on pressurized bulkheads or pressure barriers; limits air leakage regardless of type and class of plug mated with them.
E/F- Environmental Resisting with Strain Relief - designed for applications where connectors will be exposed to moisture, vibration and rapid changes in pressure and temperature.
R- Lightweight Environmental Resisting - shorter in length and lighter in weight than E and F classes, the R offers a high degree of reliability under adverse conditions; recommended for new design applications.
 
     
  Series SEE CYlindrical Connectors are manufactured in conformance to class E/F.  
     
 

Features
Series SEE connectors satisfy all the prformance requirements of JSS 50812 / MIL-C-5015 and are recommanded for conditions where vibration, moisture, pressure and/or temperature are extreme. Strain relief is supplied on most shell sizes.

Shells: Shell components are fabricated from high grade aluminium alloy. The standard hardware plating is electrically conductive cadmium plated with an olive drab chromate passivation for corrosion resistance. Other plating options include nickel plating, chrome plating and black passivation.

Contacts: Contacts are silver plated copper alloy for maximum corrosion resistance, maximum current carrying capacity and low millivot drop. Crimp and solder termination are available.

Inserts: Resilient Polychloroprene inserts provide an outstanding moisture barrier, high dielectric strength and resistance to vibration. Either pin or socket inserts can be pressurized. Other inserts options include silicon.

Strain Relief Clamp: Strain Relief clamps minimize tension at the solder well connection and provide a positive mechanical moisture seal. Complete field serviceability is possible with the strain relief clamp.

Technical & Safety Information
Plug as that part which bears the coupling nut and which is free when unmated. The mating component we refer to as the receptacle. This is normally fixed to the equipment except for the line or cable connector where both mating parts are free.

The contacts themselves are known as pin or socket respectively.

No attempt has been made to recommend operating voltages. The designer must determine his own operating voltages by the application of a safety factor to compensate for circuit transients, surges and so on.

** Contact ratings as stated are test rating only. The connector cannot withstand full rated current through all contacts continuously. Please note that the electrical data given is not an establishment of electrical safety factors. This is left entirely in the designers hands as he can best determine which peak voltage, switching surges, transients, etc. can be expected in a particular circuit.

# The 10Sl. 14S and 16S connectors require short contacts.
