A planar filter array is completely isolated from mechanical and thermal stresses by an arrangement of resilient planar gaskets which sandwich said array and electrical contact springs which also serve to isolate the array from mechanical and thermal stresses and which permit electrical connection of the individual filters in the array to external devices. The filter array and gaskets are inserted into a housing to form a filtered electrical connector the filters in the, array being connected to the housing via grounding springs and to connector pins via contact springs placed in apertures in the array.

Why it's free to use
- Filed May 4, 1990 and granted November 9, 1993. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 4, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 4, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
