Electronic magnetic interference and radio frequency interference protection of airborne missile electronics using conductive plastics

摘要

A detector assembly which includes an electrically conductive, two-piece, molded plastic housing including a relatively rigid bulkhead portion having a groove and a second dome portion having a sidewall extending over an adjacent bulkhead portion. The dome portion has a plurality of relatively flexible tabs, a part of each tab extending into the groove and making mechanical contact with the bulkhead portion via the groove to provide a press fit therebetween. An electrically conductive barrel is disposed within the housing and is electrically connected via an electrically conductive o-ring to the bulkhead to form an electrically shielded chamber within the housing in conjunction with the bulkhead and the dome portions. Equipment to be shielded is disposed within the chamber and is secured to the barrel.
