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.

[ What is claimed is:] [1.]1. An apparatus, comprising:a housing which includes first and second housing portions, and fastening structure operative to releasably couple said first and second housing portions together, said first and second housing portions defining a housing chamber within said housing when coupled by said fastening structure, and said second housing portion being made of an electrically conductive material;a member supported within said housing chamber so as to divide said housing chamber into a first chamber and a second chamber, said member being made of an electrically conductive material, and said second chamber being defined by said member and said second housing portion, said housing including structure facilitating an electrical coupling of said member to said second housing portion so that said second chamber is electrically shielded; anda circuit which is provided within said second chamber.
