Crimp Contacts
Rear-insertable, front-releasable, crimp style contacts are machined
from a copper alloy material, plated gold over nickel, and are qualified
to specification SAE AS39029.
Contacts are crimp terminated outside the connector assembly and
inserted into the appropriate cavity by means of a hand tool. Socket
contacts utilize a multi-tined construction and feature a “C” spring
which grips the tines, and ensures consistent and repetitive insertion/
withdrawal forces. Contact tines are protected by a
stainless steel shroud.
An optional pencil-clip thermocouple socket design is also offered.
See page 422 for more information on thermocouple contacts.
In addition, a dynamic “O” ring seal engages the front of the plug shell
when connectors are mated and offers yet another barrier to moisture
and containments.

Alternate Keying
All MIL-DTL-26500 Series Connector shells can be furnished with
normal or any of five alternate key positions. (See page 400). Each plug
shell has a master key and four alternate keys. The position of the
alternate keys in relation to the fixed master key determines the key
identification. Inserts are bonded to the shell in relation to the master
key, thus allowing positive protection against mis-mating when differing
circuits exist side by side.
Fluid/Temperature Resistance
The fluorosilicone compound elastomer, developed by Pyle-National,
exceeds all specification requirements and provides excellent resistance
to tear, compression set, fluids, and high temperatures.
Amphenol/Pyle’s fluorosilicone compound offered in Class R, G, E and
K is capable of reliability resisting:
- MIL-H-5606 hydraulic fluid
- MIL-L-9236 lubricating oil
- MIL-L-7808 and MIL-L-23699 lubricating oils
- MIL-J-5624 (JP-5) jet fuel
- Glycol
- Alkaline cleaning solutions of pH 10 or higher.
Test methods are as defined in MIL-DTL-26500 specification. Alternate
compounds have been developed by Pyle-National to solve unique
user requirements not addressed by the specifications.
Connectors have the capability of resisting high ambient temperatures
up to 200°C (392°F) for long periods of time, thus contributing to an
extended connector life. Connectors will withstand a combined ambient
and internal temperature due to thermal rise of current carrying
capacity of 238°C (469°F).

Firewall, Class K, connectors have the inherent ability
to resist high temperatures up to 460°F (total temperature) for extended
periods of time and can resist short time exposures (20 minutes) to
prevent passage of a direct 2000°F flame.

Connector Sealing
The insert design utilizes a combination of resilient and rigid insulators
to offer a connector with total sealing capabilities. Bonded interfaces
between the resilient and rigid dielectric components eliminate air voids
and thus protect the connector from potential degradation due to
moisture and altitude conditions.
In Firewall Class K connectors, the resilient insert forms the primary
contact seal and is bonded to a molded ceramic rigid insert. The insert
assembly is physically bonded and mechanically retained to the inside
surface of the stainless steel shell, providing a void-less, mono-block
configuration impervious to adverse environments.
A pressure seal at the connector interface is accomplished through the
aid of a coupling device which compresses the front resilient insulations
and thus offers a seal around each contact which prevents the passage
of air or moisture through the contact cavity.
Back resilient insulators are designed with a triple sealing grip at each
wire hole to offer positive sealing and prevent wicking of moisture
through the connector without the use of external clamping rings
or adapters.
