Abstract
A sealing mechanism is provided to seal a lead from a closed cavity of an apparatus. The sealing mechanism includes a mounting portion sealingly connected to the apparatus, a cap member having a recess defined therein with an elastomeric grommet compressively disposed in the recess. The elastomeric grommet has a passageway defined therethrough for the lead from the closed cavity to past through. The compressive forces induced into the elastomeric grommet applies a compressive force on the lead to provide a seal. The cap member is sealingly connected to the mounting portion. Consequently, the closed cavity in the apparatus is effectively sealed from the atmosphere and contaminants cannot enter the closed cavity and create premature failure of the component therein, such as, for example, an electrical coil.
