Single Arm backshell is designed for reliable grounding
Souraiu-Sunbank has developed the Single Arm Composite Backshell specifically for a robust, reliable performance for defence, aerospace and other harsh environments to protect cable connections from damage and provide better strain relief. The Single Arm backshell family is available in three types of configurations, straight, 45, and 90 degrees. It is designed to satisfy requirements for all sizes of MIL-DTL-38999 Series I, II, and III connectors.
The Single Arm provides support and strain relief to open wire bundles and also offers a reliable grounding option with its solderable ground lug, says Souraiu. It is flexible, allowing it to also support different plating combinations to suit the needs required for specific applications.
The Single Arm is designed to be economically cost-effective but highly reliable, says Souraiu, with high-grade thermoplastic materials intended for critical applications and environments, especially on military and commercial EWIS applications that require weight per part savings, corrosion resistance and electromagnetic interference protection.
Advantages compared to its die casted metallic counterpart include the fact that the composite families which use high-grade engineered thermoplastic are not prone to electromagnetic disturbance and stealth ability. They are also stronger in terms of vibrations due to less harmonic resonance because of the weight reduction, says Souraiu – 40 per cent lesser compared to aluminum. The weight savings of the backshell will have a positive impact on the total weight of the electrical system and contribute to fuel savings and a lighter environmental footprint per aircraft, Souraiu adds.
The Single Arm technology also provides detent self-locking. This is a ratcheting coupling ring using non-corrosive clips located within. The audible ratcheting noise during the installation process guarantees correct engagement.
Souraiu-Sunbank specialises in interconnect solutions engineered to withstand the harshest of environments (aeronautics, space, defence, transport, energy, industrial equipment, healthcare devices, and lighting).
It invests in R&D and manufacturing facilities to produce solutions that comply with environmental requirements and international trade rules.
The company’s range of products are designed using advanced electrical and optical connection technologies. All are suitable for use in non-hazardous environments as well as those involving extreme temperatures, strong vibrations and corrosive liquids, and meet specific international market standards.
