Meritec Design Win: Military Cable Assembly

Meritec Design Win: Military Cable Assembly
Battlefield ready, Meritec’s “Houdini” Custom
Cable Assembly allowed the use of their Medical
Division technology to solve a Military application.
The product calls for a 5-pin cable harness to
be mated to a rechargeable battery pack worn by
a soldier during training exercises. The device
powered the targeting laser mounted on their
weapons, similar to Laser Tag.
The unique requirement was to mate to a
standard female connector mounted to the battery
and not only have it be shielded for EMI purposes
but, to have it be waterproof under one meter of
water for 30 minutes.
From clean room precision requirements of
an operating room to the harsh environment of a
battlefield, Meritec’s Xtreme High-Speed Xperts
rise to the innovation demands of Customer
commands.

The heart of the assembly is the
overmolded rubber shield and gasket.
Instead of having to use the conventional steel
stamped housings and O-rings to terminate the
connection along with potentially having to pot
the entire assembly to achieve waterproofing
we achieved all of the above with one simple
overmold.
The cable shield is exposed and the
conductive rubber bonds to it forming a low
resistance ground path. The rubber gasket
design is integral to the overmolding and is
proven to The Customer waterproofing
requirement.
The Customer was impressed enough that
they waived a test of prototypes between
vendors and awarded us the contract directly.
The following slide shows the details of
the design.
