O-ring bellows connection assembly with optional heat shield and lock and seal for bellows tube

Abstract

An improved connection apparatus for connecting a tube bellows to a spigot for a battery pack (of an electric vehicle “EV”) having a heat deflector including an outer sleeve and a wire mesh ring. The spigot is connected to a battery pack in an EV having a cooling system. The cooling spigot of the EV is configured to accept a flow of glycol to cool the battery. The connector of the bellows of the present application adds an o-ring groove to the bottom of the spigot. The apparatus is then hydroformed to include internal o-ring grooves and corresponding o-rings are positioned into those grooves. The top o-ring groove seals in a typical o-ring application and the bottom o-ring groove acts as a lock. When the cup assembly is pressed onto the spigot, the o-rings compress as part of their normal function when using o-rings as it moves down the spigot.
