MIL-C-26482 Series I Connectors
KPT connectors are a series of general - purpose,
environment - resistant, miniature circular connec-
tors, qualified for use in industrial applications
calling for quick - disconnect connectors with fixed
contacts
for
solder
termination.
These miniature circular connectors are grouped
into two series ranging from general purpose solder
pot connectors . . . to high performance, crimp con-
nectors . . . to connectors with high contact densi-
ty. This broad range provides the most complete
family of 26482 connectors available today. The
versatility of these connectors is proven by the
fulfillment of requuirements ranging from general
purpose to space environmental.
KPT/KPSE
In addition to the two basic series, connectors for
special applications are also available. They include
RFI filtering versions (with loss pass internal filter
pin contacts), hermetic connectors for high pres-
sure watertight requirements, and twist - on pull - off
couplers for MIL-C-26482 plugs.
This series is intermateable and intermountable
with all MIL-C-26482 connectors, whether solder
or crimp type and is available with many materials,
finishers and configurations.

KPSE High Performance Crimp Contact Connectors
Environment -resistant
Voidless integrally molded insulator
Front-release, crimp snap-in contacts
Closed entry socket contacts
4 moisture seals for complete sealing
Contact clip protected in hard dieletric
Positive insert-to-shell mechanical retention
KPSE environment-resistant, miniature circular,
quick
disconnect
connectors,
qualified
to
MIL-C-26482, are designed for the exacting re-
quirements of today's electronic industry. The KPSE
features an insulator which is mechanically retained
in the shell by a positive, hard plastic-to-metal lock
retention augmented by a reliable adhesive bond.
Complete moisture sealing is achieved by four
seal; shell, peripheral, interfiacial and wire seals.
Crimp snap-in contacts are retained in clips that are
completely encased in a tough hard dieletric wafer,
thus protecting the clips tines from damage. Closed-
entry socket contacts facilitate positive mating.
The KPSE series is intermateable, intermountable
and interchangeable with all MIL-C-26482 connec-
tors, whether crimp or solder type, and is avialiable
with many materials, finishes and configurations.

MIL-C-26482.
mates with any connector designed to
CRIMP, SNAP-IN CONTACTS
are designed to MIL-C-39029 and can be crimped
with the standard M22520/1 crimp tool.
CLOSED-ENTRY SOCKET CONTACTS eliminate damage from abuse by test
probes and help to correct any misaligned pins during engagement.
CONTACT INSERTION is accomplishted from the rear of the connector.
When the contact is fully inserted, the clip tines snap securely behind
the contact shoulder.
CONTACT EXTRACTION is accomplished with a front-inserted extraction
tool. Pressing the tool plunger pushes the contact out thru the rear of
the connnector.
CONTACT RETAINING CLIP
is completely encased in a tough plastic wafer to
protect the clip from damage.
COMPLETE MOISTURE SEALING
is achieved by combining four seals: shell,
peripheral, interfacial and wire seals.
SHELL SEAL is effected when the plug shell pushes against the sealing
ring in the receptacle when the connectors are mated.
PERIPHERAL SEAL around the edge of the pin insulator is designed so
that mating the connector puts tension on the seal and greatly reduces
compression set.
INTERFACIAL SEAL is achieved by the insulator faces meeting when the
plug and receptacle are mated.
WIRE SEAL is accomplished by a mulitiple ripple design, exceeding the
wire sealing requirements of MIL-C-26482.
POSITIVE INSERT-TO-SHELL MECHANICAL RETENTION
with hard plastic wafer
firmly locked into a groove in the shell, in addition to a strong adhesive
bond between the insert and shell.
