Cryocooler Thermal Links / Straps

In addition to our popular CuTS® Standard Product Line, Technology Applications, Inc. designs and manufactures thousands of custom OFHC copper thermal straps for space, airborne and ground-based/terrestrial use in aerospace, commercial, laboratory and defense applications.  Custom CuTS® typically have the same unit cost as their standard counterparts, but with the addition of a small NRE/design fee.

In many cases, a simple, standardized rectangular end fitting will not work for certain applications, especially those with very restricted interface geometry and/or "end fitting envelopes," as in electronics boxes and cold head / cryocooler applications, for example.

As well as unique & exacting end fitting/terminal block design and machining requirements in many custom programs, CuTS® customers often have a need for a comprehensive range of custom "add-ons," or options, including: helicoil inserts, different copper/cabling rope diameters and types, serialization, etc.

Custom End Fitting and Strap Design Options

End fittings can be designed into a number of complex shapes, and incorporating a wide range of features. From circular end fittings (commonly used on strap assemblies designed for use on cold heads / cryocooler applications), to offset fittings (in which the flexible portion of the strap must sit higher or lower than the fittings), pipe interfaces, "c-clamp" and "battery terminal-type" fittings, nested configurations, and multiple armed straps (TAI has designed and fabricated straps with 2 - 8 arms), the possibilities are endless; and TAI has built them all!
