Filtered terminal block assembly

A terminal block assembly comprising:

• a terminal block housing;
• at least one terminal stud extending through said terminal block housing;
• a filter assembly coupled to said at least one stud, said filter assembly comprising at least two filtering elements, and at least one of said filtering elements being a discoidal capacitor;
• a first and second resilient contact element attached to a respective one of opposite ends of said filter assembly, each of said first and second contact elements electrically coupled to a respective one of said filter elements and to said at least one terminal stud, said first and second contact elements mechanically isolating said filter element from structural stress.

A terminal block assembly comprising:

• a terminal block housing;
• a plurality of terminal studs extending through said terminal block housing;
• a filter assembly coupled to each respective one of said plurality of studs, at least one of said filter assemblies comprising at least one discoidal capacitor;
• a resilient contact element electrically coupling each said filter element to the respective terminal studs, said contact element mechanically isolating said filter element from structural stress;
• and
• a second housing coupled to said terminal block housing over said filter assemblies, said filter assemblies enclosed between said housings.

A method for assembling a terminal block assembly including a base assembly, a filter assembly, a ground plate and a cover assembly;

• the base assembly including a terminal block housing having a terminal stud extending therethrough;
• the filter assembly including a resilient contact element and a filter element;
• and the cover assembly including a second housing and a fastener, said method comprising:
• positioning the filter assembly over the terminal stud wherein the resilient contact element electrically contacts the stud;
• positioning the ground plate over the filter assembly;
• electrically connecting the ground plate and the filter assembly;
• positioning the second housing over the filter element;
• and
• fastening the second housing to the terminal block housing such that the filter element is enclosed between the terminal block housing and the second housing.
