摘要
A detector/seeker assembly which includes an electrically conductive molded plastic two-piece housing including a relatively rigid bulkhead portion having a groove and a dome portion having a sidewall extending over and adjacent to the 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 first chamber within the housing for containing equipment to be shielded from electromagnetic radiations therein. A second chamber for containing optics therein is provided by a groove disposed in the barrel and one in the dome with an o-ring disposed in the groove and contacting the barrel and the dome to provide a seal therebetween.
