Abstract

In electrical equipment it is necessary to provide a good electrical connection between parts such as the cover and the frame. To provide a good continuous connection or seal it is necessary to control the dimensional cross-section of the seal and to provide a seal having good conductivity therethrough which includes the interface between the seal mounting means and the seal. It is also necessary that the seal installation cost be kept to a minimum.

Conductive Flexible Seal and Mounting Strip

In electrical equipment it is necessary to provide a good electrical connection between parts such as the cover and the frame. To provide a good continuous connection or seal it is necessary to control the dimensional cross-section of the seal and to provide a seal having good conductivity therethrough which includes the interface between the seal mounting means and the seal. It is also necessary that the seal installation cost be kept to a minimum.

A conductive rubber or rubber-like gasket material 10 is extruded in a continuous manner onto a metal strip 12 to provide a dimensionally stable gasket surface for proper electrical contact to an adjacent surface. The interface 14 between the conductive gasket material 10 and the metal strip 12 results in an improved electrical path through the gasket or seal from the mounting surface to the adjacent contact surface. The adhesive used in the interface 14 between the rubberlike gasket material 10 and the metal strip 12 must have sufficient adhesion such that any separation failure would occur in the material of which the rubber gasket 10 is made rather than in the adhesive itself. The metal strip 12 can be shaped and provided with a set of holes or slots or formed into clips to mount the combination of the seal 10 and mounting strip 12 with a reduction in labor. A variety of shapes of conductive gaskets and mounting strips are possible; therefore, a combination must be select...
