Electronic filter assembly

Abstract

A filter assembly, comprising first and second terminal caps in opposing relation to each other. The caps are physically and electrically coupled to each other. First and second circuit boards are physically coupled to the first cap. The first circuit board includes—(i) front and rear surfaces, (ii) a first circuit located on either or both of the front and rear surfaces, (iii) a ground lead connected to the first circuit, and (iv) a first electrical terminal coupled to the first circuit. The second circuit board includes—(i) front and rear surfaces, (ii) a second circuit located on either or both of the front and rear surfaces, (iii) a ground lead connected to the second circuit, and (iv) a second electrical terminal coupled to the second circuit. The first and second circuits are electrically coupled to each other, and each are electrically coupled to the first terminal cap.

We claim:  
     
         1 . An electronic filter assembly of the type that includes a female terminal cap having a fitting portion and containing a terminal passage through the fitting portion, and a collet assembly secured in and substantially closing the terminal passage of said female terminal cap, wherein said collet assembly comprises: an insulator, made from a single piece of insulator material, containing a bore therethrough; a collet terminal extending through the bore of the insulator; and a seal located inside the terminal passage of said female terminal cap, between the collet terminal and said female terminal cap.  
     
     
         2 . The electronic filter assembly of  claim 1 , wherein the collet terminal has at least one barb which penetrates the insulator material of the insulator, to help prevent moisture from entering said filter housing between the bore of the insulator and the collet terminal.  
     
     
         3 . The electronic filter assembly of  claim 1 , wherein the insulator of said collet assembly has a substantially cone-shaped nose portion.
