MIL-DTL-32628/01-X Reusable EMI Shield Termination Band on MIL-DTL-38999 Electrical Connector Accessory Braid Termination / Tensile Qualification Test
Abstract
Reusable constant force spring force bands (CFSB) M32628/01-10 thru 13 (ISOTDS1 thru 4) shield termination bands were evaluated for tensile strength performance as described in SAE AS85049 and AS85049/128. The shield bands are employed on shielded wire harness constructions to secure the shield on to the connector accessory/backshell banding platform in order to protect the wires in the bundle from electromagnetic interference (EMI). Four sizes of CFSBs (M32628/01-X, ISOTDS1-X) shield termination bands were tested on the eight shell sizes of connector accessories, thus eight test articles. The shield bands were installed on shield braid of suitable width A-A-59569, on shell size A- H of M85049/88 backshells, mated to interface connector fixtures. The M85049/88 backshells mate to the Mil-Dtl-38999 Series 3 connectors, the most common electrical connector types employed in aerospace applications. The braid retention / tensile tests were performed as per AS85049/128F, para 2a requirements. All shield bands, configurations and sizes tested in this effort passed tensile test requirements. None of the M32628/01-10 thru -13 constant force spring band configuration test articles exhibited shifting, loosening, or other damage after exposure to prescribed linear force. All CFSB test articles passed tensile testing.
