Let’s Do the Twist

The first step in TwistPin manufacturing is fabri-cation of the pin bundle. Three strands of copper wire are wound together to make a core, then seven strands of beryllium copper are wound over the core. The wire is heat treated, then cut into short lengths and welded at each end. The inert gas weld process utilized in the manufacture of the pin creates a hemispherical radius at both ends of the bundle.

Next, pin bundles and crimp sleeves are loaded into feeder bowls on an automatic assembly machine. The machine inserts the bundle into the sleeve and crimps the two parts together. The machine then deforms the wire bundle to create a precision bulge. Finally, the contact is machine inspected, and plated. This fully automated process allows Microway to produce connectors which utilize superior TwistPin contacts as quickly as other manufacturers can produce conventional stamped contact connectors. The difference is not lost on the many OEMs who have come to rely on Microway as the supplier of choice for high reliability microminiature connectors. Ideally suited for applications which require reduced size and weight, Microway’s TwistPin connectors serve in missile systems, avionics, battlefield gear, radar and other demanding military applications. The rugged design also permits a select range of commercial applications, such as in satellite telecommunications systems, geophysical exploration, medical diagnostics and industrial equipment.
