MIL CONTACTS
PRECI-DIP has tapped its unique expertise and tested know-
how to develop new MIL socket contacts based on the clip
technology.
Two socket contact technologies are available:
hooded contacts using the reversed clip
hoodless contacts using the Eagle Grip clip.
These contacts have successfully passed all the qualification
tests according to AS39029 and are listed on the QPL.
We are also manufacturing the corresponding precision-
machined pin contacts.
Hooded contacts using the reversed clip patented
technology
CONTACT DESIGN
The contact consists of three parts, separately
manufactured and made of different base materials. This design
allows to optimise the performance and to select the most
appropriate production process individually:
Contact body made of machined brass
Beryllium-copper clip insert achieved by precision stamping
process
Protection hood made of deep-drawn stainless steel
Separate electroplating processes of body and clip allow the
best cost-performance ratio (localized finish). The assembly of
the three parts is then carried out on dedicated, fully automatic
assembly lines.
Reversed clip contacts are presently available in size 12, 16, 20
and 22. This proprietary technology developed by PRECI-DIP, is
protected by international patents.
ADVANTAGES AND CHARACTERISTICS
In comparison with the alternative slotted contact body design,
the reversed clip concept has several advantages:
Smaller difference between insertion and extraction force
Reduced dispersion of the force values
Higher redundancy at the level of the contact point, thanks to
6 or 8 contact fingers
Hoodless contacts using the eagle grip clip patented
technology

CONTACT DESIGN
The hoodless contact consists of two parts: the contact
body and the clip (separate pressure member) are made
from different base materials.
The high-speed screw machined contact body is made of
brass.
The use of quality crimping brass renders the
annealing operation unnecessary.
The precision stamped and formed Eagle Grip clip is
made of beryllium-copper.
Separate electroplating processes of the body and clip
offer the best cost-performance ratio.
Automatic assembly lines are designed by our engineers to
conduct the body and clip assembly.
The clip is precisely positioned in the outer shell and firmly
held in place between a shoulder and the crimp lip.
In-line mechanical check is carried out on the assembly
machine.
Eagle Grip clip hoodless contacts are presently available in
sizes 16, 20 and 22.
This PRECI-DIP proprietary technology is protected
by international patents.
ADVANTAGES AND CHARACTERISTICS
2-piece contact without hood
Fully automatic assembly process with in-line mechanical
check
Localized finish: body and clip are plated separately
High surface quality with a stamped and formed clip
Precision rolling surface finish in the contact area
Better contact redundancy thanks to 3 or 4 contact fingers
Repeatability in the manufacturing process of the
clip (tooling and stamping)
Limited difference between insertion and extraction mating
forces
Narrow range of the force values
Fully integrated manufacturing process on one single production site
