MIL-DTL-32628/01-X Reusable EMI Shield Termination Band on MIL-DTL-38999 Electrical Connector Accessory Braid Termination/Tensile Qualification Test

Reusable constant force spring force bands (CFSB), employed on shielded wire harness constructions to secure the shield onto the connector accessory/backshell banding platform in order to protect the wires in the bundle from electromagnetic interference (EMI), were evaluated for tensile strength performance as described in SAE AS85049™ and AS85049/128™.

Naval Air Warfare Center, Patuxent River, Maryland

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 M32628/01 shield termination 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 constant force spring bands were tested applied to eight shell sizes of connector accessories/backshells. The CFSBs were installed on A-A-59569 shield braid of suitable width, 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 braid retention/tensile test requirements are per AS85049/128F™, para 2a. To pass the test, the M32628/01-10 thru -13 constant force spring band test articles may not shift, loosen, break or slip after exposure to the prescribed linear force.
