Abstract
An anti-bounce dampener assembly for dampening the closing impact force between vacuum interrupter contacts. The dampener assembly includes a dampening spring positioned within a contact adapter, a guide tube extending through the contact adapter and the spring, where the guide tube is coupled to a fixed contact stem, and a bolt extending through the guide tube and being rigidly secured to the fixed contact stem. An impact force caused when the vacuum interrupter contacts contact each other when the vacuum interrupter is closed causes the fixed contact stem, the guide tube, the bolt and the vacuum interrupter to move against the bias of the spring and dampen the impact force. A flexible strap is electrically coupled to the fixed contact stem and the contact adapter, and flexes when the stem moves so as to maintain electrical coupling between the fixed contact stem and the contact adapter.
