VIBRATION LEVELS
Not all connector coupling nuts are the same when it comes to vibration and shock Connector couplings designed for vibration and shock resistance include locking and ratcheting technologies such as used on Glenair SuperNine® connectors. This technology is a high-performance benchmark of this series. SuperNine is the only available MIL-DTL-38999 Series III qualified to the Bell 299-100-B29 high-vibration specification. 1 Backshell-to-connector attachment interfaces vary from series to series. For heavy-duty applications such as large form-factor power cables, a splined interface such as is used on MIL-DTL-28840 shipboard connectors and the Glenair PowerTrip™ series are preferred, particularly if resistance to high levels of vibration and shock is an application requirement. Cable strain-relief utilizing appropriate backshells, boots, banding solutions, connector types, overmolded cable design, and so on is critical to interconnect performance in harsh vibration and shock applications. The reduction of severe bend moment forces on cables through appropriate routing is a powerful tool in ensuring long-term durability. 2 3
