Connectors Business Unit Fast Facts MIL-DTL-38999 SERIES III SCREEN TRAPTM BACKSHELLS Originally designed, and proven by TT electronics New Chapel Electronics, the trademarked ‘Screen Trap’ backshell is now adapted for use with all MIL-DTL-38999 Series III connectors. The concept is contained in patents, GB2427079B, GB2427080B, GB2427081B and subject of other patent applications. This series of adapters provides a simplified method of grounding over all shields. The shield/braid is secured between a male and female thread providing a good bonding joint. No additional tooling is required to terminate Screen TrapTM backshells. Simple but effective EMI/RFI and environmental protection. Market Segments Adoption in high reliability applications including traditional applications associated with MIL-DTL-38999 Series III connectors Applications Defence Surveillance systems Thermal imaging Aerospace Fixed wing Rotary wing Landing gear Missile systems Features No tooling required for assembly Grounded backshell, shield termination, environmental sealing and mechanical strain relief Tested to the American Specification AS85049 for connector backshells Base materials & finishes Aluminium Cad, Electroless Nickel, Nickel PTFE, Zinc Cobalt Passivated Stainless Steel (not in AS85049) Our advantage All Screen Trap™ adaptors are capable of terminating single, double or optimised screens thereby making the Screen-Trap™ ideal where RFI, EMI, EMP, Tempest or HIRF conditions apply. Not widely promoted by competition that may prefer to offer more their own designs, ie Constant Force Springs, Tinel Ring, Banding Style Lower material cost than Banding Style termination Fast termination and therefore lower installation cost than other technologies Ease of repair © Copyright TT electronics, 2012.
